Introduction
The genus Hemopsis was erected by Kirti and Rose (1987) with Botysdissipatalis Lederer, 1863 as the type species, and Botysangustalis Snellen, 1890 was transferred to Hemopsis simultaneously. Both species were previously placed in the genus Syllepte Hübner, 1825 (= as misspelling Sylepta) by Hampson (1896). So far, Hemopsis is comprised of only these two species (Nuss et al. 2003–2024), and only Hemopsisdissipatalis has previously been recorded in China as “Sylepta” by Caradja (1925).
In appearance, the adults of Hemopsis species have faintly yellow wings with brown or fuscous markings, with an orbicular stigma, discoidal stigma, and postmedial line, which are common markings in Spilomelinae, as well as distinct broad brown bands along the outer margins of both wings. In addition, the reduced uncus in the male genitalia and the arc-shaped signum in the female genitalia are also markedly diagnostic characteristics of the genus.
Four Hemopsis species, including three new species from China, are recorded in the present study, with descriptions of their external and genitalia morphology.
Materials and methods
Taxon sampling
Specimens were collected by light trap at night and killed by ammonium hydroxide or ethyl acetate. Some specimens were soaked in anhydrous alcohol and stored at −20 °C or −80 °C in a refrigerator.
For phylogenetic analyses based on the mitochondrial COI barcode region, the outgroup taxon, Nomophilanoctuella (Denis & Schiffermüller, 1775), is very different from Hemopsis species in appearance. Based on the adult photos from the National Center for Biotechnology Information (NCBI) and description of the genital characteristics of Ategumia Amsel, 1956 (Kirti and Rose 1986: figs 4–7; Mally et al. 2019: fig. 13B), we found this genus was very similar to Hemopsis in external adult morphology and genitalia characteristics. Therefore, we chose the South American Ategumiamatutinalis (Guenée, 1854), the type species of Ategumia, as the ingroup taxon together with Hemopsis species.
The preparation of genitalia mainly follows Li and Zheng (1996). Morphological terminology mainly refers to Maes (1995) and Mally et al. (2019). The photographs of the adults were taken with a digital camera (Canon EOS 5D), and the genitalia photographs were obtained with a digital camera (Leica DFC 450) attached to a stereomicroscope (Leica M205 A).
The specimens, including the types of new species, are deposited in the Insect Collection, Southwest University, Chongqing, China (SWU). The type specimen photos of Ategumiaadipaliskwantungialis (Caradja) and Ategumiaadipalisnigromarginalis (Caradja), which we referred to in “Discussion”, are from the “Grigore Antipa” National Museum of Natural History, Bucharest, Romania (MNHGA).
DNA extraction, PCR amplification, and sequencing
Three Hemopsis species and one outgroup species were sequenced in the present study. Total DNA was extracted from the dried legs using a TIANGEN DNA kit, following the manufacturer’s instructions. The mitochondrial COI gene’s 658-base-pair (bp) barcode region (Hajibabaei et al. 2006) was PCR amplified using the LepF1 and LepR1 primers. After verifying PCR products by running them on a 1% agarose gel, sequencing was conducted by Shanghai Sangon Biotech Co., Ltd (Shanghai, China) using the same primers as those used in PCR. In total, eight sequences from three Hemopsis species and three sequences from the outgroup species Nomophilanoctuella were obtained and uploaded to the NCBI. In addition, three sequences of another ingroup species, Ategumiamatutinalis, recorded as Ategumiasp.matutinalis DHJ03 in NCBI, were downloaded from the NCBI. Details of the specimens used for mitochondrial COI gene sequencing and phylogenetic analysis are provided in Table 1.
Data analysis
The obtained sequences were searched for similarity using the BLAST tool of the NCBI database to compare nucleotide sequences between our specimens and the database. All COI sequences were manually aligned using MEGA X and then were translated into amino acid sequences for visual correction. Intraspecific and interspecific genetic distances were calculated using the Kimura 2-parameter (K2P) distance model (Kimura 1980). A phylogenetic tree was constructed using the maximum-likelihood (ML) method with 1,000 bootstrap replications (Stamatakis et al. 2008) based on the data of COI sequences. Hemopsis species and Ategumiamatutinalis were the ingroups, and Nomophilanoctuella, was regarded as the outgroup.
Results
DNA sequence analysis
A total of 14 COI sequences, including three sequences of the outgroup species, were analysed. Three monophyletic clades for Hemopsis were observed in the phylogenetic tree and well separated from the outgroup species (Fig. 1). The pairwise genetic distances within and between these lineages are given in Table 2. In Hemopsis, the intraspecific genetic distance is 0.00%, and the interspecific genetic distance ranged from 6.84% to 8.15%. The genetic distances between the ingroup and outgroup species ranged from 9.12% to 10.41%. The maximum intraspecific COI genetic distance was much less than the minimum interspecific distance (Table 2). The results of the phylogenetic analysis were in full agreement with our morphological hypotheses for the investigated species.

C0D710DB-AEA4-577F-9ECB-B70904C299FC
Hemopsis Kirti & Rose, 1987: 379. Type species: Botysdissipatalis Lederer, 1863, by original designation.
Diagnosis.
This genus is externally similar to Mecyna Doubleday, 1849 in appearance, but it can be distinguished by having the uncus reduced to a flat arch and by the long, balloon-shaped corpus bursae with a well-sclerotized arciform signum, while in Mecyna, the uncus is conical, and the corpus bursae is oval and has a longitudinal banded signum composed of granules. In addition, Hemopsis is very similar to Ategumia in external adult morphology and genitalia characteristics, but it can be distinguished by the forewing having the postmedial line excurved and merged with the outside broad band between wing veins M_2_ and CuA_2_; in Ategumia, the postmedial line of the forewing is slightly excurved and intersects with, or is separated from, the outside broad band between M_2_ and CuA_2_.
Redescription.
Adult. Body yellowish brown; wings faintly yellow with brown or fuscous markings. Frons rounded. Antenna filiform; male with short cilia ventrally. Labial palpus obliquely upturned, with basal two-thirds white, brown distally; the third joint short, projecting forward (Fig. 2A). Maxillary palpus filiform. Forewing and hindwing with broad brown band along outer margin. Forewing with postmedial line from proximal two-thirds of costa and excurved between M_2_ and CuA_2_, then incurved to discoidal stigma below and sinuous to inner margin; cell somewhat less than half length of wing; R from cell at three-fourths above; R_S1_ very close to R_S2+S3_; R_S2_ anastomosed with R_S3_ about three-fifths beyond cell; R_S4_ slowly curved and close to R_S3+S4_ at base; M_2_, M_3_ and CuA_1_ from posterior angle of cell and uniformly spaced at the base; CuA_2_ from cell at three-quarters below. Hindwing with outer margin slightly protruded at Rs; cell less than one-third length of wing; discocellulars slightly incurved; Rs with one-quarter length anastomosed with Sc+R at base; M_2_, M_3_ and CuA_1_ from posterior angle of cell; CuA_1_ curved and approximated to M_3_ at base; CuA_2_ from cell at two-thirds below (Fig. 2B). Legs long and slender; middle tibia with inner spur about twice length of outer spur; hind tibia with outer proximal spurs one-third length of inner proximal spurs.
Hemopsisdissipatalis, male A head B wing venation, wing slide no. YCJ23003.
Male genitalia. Uncus reduced to a flat arch; gnathos absent; valva tongue-shaped, bearing dense, long setae. Costa well sclerotized, inflated near base. Sacculus broad, protruded to base of fibula. Fibula hook-shaped, directed toward sacculus and distally curved toward costa. Saccus developed, triangular, with rounded end. Juxta U-shaped and sclerotized. Phallus cylindrical, with multiple cornuti.
Female genitalia. Papillae anales densely setose. Antrum slightly sclerotized. Ductus bursae marked with well-developed and sclerotized colliculum. Ductus bursae shorter than corpus bursae. Corpus bursae long balloon-shaped, with a well-sclerotized, arciform signum.
Distribution.
China, India, Indonesia, Sri Lanka, Japan (Hampson 1896; Caradja 1925; Kirti and Rose 1987).
Remarks.
Although Ategumia is very similar to Hemopsis in external adult morphology and genitalia characteristics, we found they can be distinguished by the pattern of postmedial line of forewing. Moreover, they were well separated from each other in ML tree based on DNA barcodes.

Distribution.
China (Chongqing, Hunan, Yunnan, Guangxi, Guangdong, Hainan, Fujian, Taiwan), Indonesia, India, Sri Lanka, Japan (Hampson 1896; Caradja 1925; Kirti and Rose 1987).
Remarks.
Hemopsisnr.dissipatalis of Matsui et al. (2022) is quite different from H.dissipatalis (Lederer, 1863) described and illustrated by Kirti and Rose (1987). According to Matsui et al. (2022), H.dissipatalis identified in Japan, is characterized by the conical uncus and the corpus bursae having a transverse signum. However, according to the description and illustration by Kirti and Rose (1987), the uncus of Hemopsis species is reduced and the female genitalia of H.dissipatalis has a longitudinal signum. In addition, we found H.nr.dissipatalis illustrated by Matsui et al. (2022; supplementary file S1) has a spindle-shaped valva; the fibula is well developed, with its tip curved downward toward sacculus; and the phallus has claw-like, larger, leaf-like cornuti. However, in H.dissipatalis, the valva is tongue-shaped; the fibula is short and small, tip curved upward toward the costa; and the phallus has a bunch of small, spine-like cornuti. Therefore, we do not consider H.nr.dissipatalis of Matsui et al. (2022) to be a species of Hemopsis.

Diagnosis.
This species is similar to H.angustalis in appearance, but it can be distinguished by its wings which have relatively larger stigmas, and the centrally lighter brown discoidal stigma; postmedial lines are smooth and somewhat thinner; the male lack a black anal tuft; the phallus has three anteriorly connected cornuti, one short and laminar and two long bands (one curved and distally bilobed and the other relatively straight, longer and distally pointed). In H.angustalis, stigmas are relatively smaller, and the discoidal stigma is uniformly fuscous; postmedial lines are somewhat punctated and thicker; the male has a black anal tuft; the phallus has three cornuti, with one small and spine-like and two long bands (one curved and the other relatively straight, longer and distally pointed) (Kirti and Rose 1987: fig. 6).
Description.
Adult (Fig. 3B). Wingspan 23.0–27.0 mm, forewing length 12.0–14.0 mm. Frons brown. Vertex yellowish brown. Antenna yellowish brown, ventral cilia about one-quarter length of flagellomeres diameter in male. Maxillary palpus brown, white at base. Patagium yellowish brown. Tegula light brown, distally yellowish white. Forewing and hindwing pale yellow, with stigmas, lines, and broad bands along outer margin brown. Forewing diffused brown at base and proximal half of costal; orbicular stigma nearly round, sometimes light centrally; discoidal stigma reniform, centrally light; antemedial line closely accompanied by a brown square spot below orbicular stigma; postmedial line distinctly excurved and merged with outside broad band between M_2_ and CuA_2_. Hindwing with discoidal stigma reniform, centrally pale yellow; postmedial line distinctly excurved between M_2_ and CuA_2_, then incurved to discoidal stigma below and curved down to posterior margin, well separated from outer broad band; outer broad band narrowed at middle. Cilia pale yellow, with brown basal line. Legs off-white; front coax and femur light brown; tibia distally brown; hind tibia with outer distal spurs two-thirds length of inner distal spurs. Abdomen dorsally yellowish brown and terminally white at each segment; ventrally white.
Male genitalia (Fig. 4C, D). Valva very gradually narrowed distally, distal end rounded. Fibula comparatively well developed, with tip sharp. Phallus with three anteriorly connected cornuti: one short lamina and two long bands (one curved and distally bilobed and the other relatively straight, longer, and distally pointed).
Female genitalia (Fig. 4J). Apophyses anteriores about 1½ times length of apophyses posteriores. Ductus bursae approximately one-third length of corpus bursae. Corpus bursae elliptical anteriorly, posterior third slightly narrowed and weakly sclerotized; arciform signum longitudinal.
Etymology.
The specific name is derived from the Latin abstractus, meaning separated, in reference to the postmedial line of the hindwing well separated from the outer broad band.
Distribution.
China (Yunnan, Guangxi).

Diagnosis.
This species is very similar to H.dissipatalis in appearance, but it can be distinguished in having the hindwing with the postmedial line distinctly excurved between M_2_ and CuA_2_ and closely accompanied by three pale yellow spots outside; the valva with its distal end nearly triangular and apically pointed; the phallus with three anteriorly connected cornuti; the corpus bursae with its posterior half cystiform and slightly narrower than the anterior half; and a transverse arciform signum. While in H.dissipatalis, the postmedial line of hindwing is slightly excurved between M_2_ and CuA_2_ and has no spot accompanied outside; the valva is very gradually distally narrowed and apically rounded; the phallus has a bunch of small, spine-like cornuti; the posterior third of corpus bursae is distinctly narrowed; and the arciform signum is longitudinal. In addition, male genitalia of H.coalita are similar to H.abstracta, especially in the shape of the cornutus, but H.coalita can be differentiated by the valva which has its distal end nearly triangular and apically pointed, the corpus bursae which is distinctly medially constricted, and the transverse arciform signum. In H.abstracta, the distal end of valva is nearly semicircular and apical end rounded, the corpus bursae is slightly posteriorly constricted, and arciform signum is longitudinal.
Description.
Adult (Fig. 3C). Wingspan 22.0–28.0 mm, forewing length 12.0–14.0 mm. Frons brown. Vertex yellowish brown. Antenna yellowish brown; ventral cilia about one-quarter length of flagellomeres diameter in male. Maxillary palpus brown, white at base. Patagium yellowish brown. Tegula light brown, distally yellowish white. Forewing and hindwing pale yellow, with stigmas, lines, and broad bands along outer margin fuscous. Forewing diffused fuscous at base one-third; costal fuscous, pale near postmedial line; orbicular stigma nearly round; discoidal stigma reniform; antemedial line closely accompanied by a square spot below orbicular stigma; postmedial line distinctly excurved and merged with outside broad band between M_2_ and CuA_2_. Hindwing with discoidal stigma reniform, centrally pale yellow; postmedial line distinctly excurved between M_2_ and CuA_2_, closely accompanied by three pale yellow spots intersected with outside broad band, then straight to discoidal stigma below and curved down to posterior margin. Cilia fuscous, with pale-yellow basal line. Legs off-white, front coax and femur light brown, tibia distally brown; hind tibia with outer distal spurs two-thirds length of inner distal spurs. Abdomen yellowish-brown dorsally and terminally white mixed black at each segment, ventrally white.
Male genitalia (Fig. 4E, F). Valva gradually narrowed distally, with distal end nearly triangular and apical end pointed; fibula slender. Phallus with three anteriorly connected cornuti, one short lamina, and two long bands (one curved, distally bilobed and the other relatively straight, longer, and distally pointed band).
Female genitalia (Fig. 4K). Apophyses anteriores about two times length of apophyses posteriores. Ductus bursae approximately one-third length of corpus bursae. Corpus bursae with anterior half nearly elliptical, posterior half cystiform and weakly sclerotized, distinctly constricted medially; arciform signum transverse.
Etymology.
The specific name is derived from the Latin coalitus, meaning connective, in reference to the three connected cornuti.

Diagnosis.
Externally this species is very similar to H.coalita sp. nov. and difficult to distinguish from each other except by genital characteristics. In H.heteroidea, the distal end of valva is nearly semicircular and the apical end is rounded; the phallus has two separate, banded cornuti; one is long and wide and the other is thin and short. The posterior half of corpus bursae is narrowed and about half the width of the anterior half. In H.coalita, the distal end of the valva is nearly triangular and the apical end is pointed; the phallus has three anteriorly connected cornuti, one short lamina, and two long bands; and the posterior half of the corpus bursae is cystiform and slightly narrower than the width of anterior half.
Description.
Adult (Fig. 3D). Refer to the adult description of H.coalita because it is externally identical.
Male genitalia (Fig. 4G, H). Valva very gradually narrowed distally, distal end nearly semicircular and apical end rounded; fibula slender. Phallus with two separate, banded cornuti, one long, wide, and distally pointed, the other thin and short.
Female genitalia (Fig. 4L). Apophyses anteriores about two times length of apophyses posteriores. Ductus bursae approximately one-quarter length of corpus bursae. Corpus bursae with anterior half nearly oval, posterior half sclerotized and narrowed, about half width of the anterior half; arciform signum transverse.
Etymology.
The specific name is derived from the Latin heteroideus, meaning different shapes, in reference to two different banded cornuti.
Distribution.
China (Chongqing, Hunan, Guangxi, Guangdong).
Discussion
The reduced uncus in the male genitalia in Hemopsis is also found in Ategumia, Bocchoris Moore, 1885, Diasemia Hübner, 1825, and Choristostigma Warren, 1892. Among these genera, Ategumia, Bocchoris, and Diasemia belong to Nomophilini (Mally et al. 2019). We found that the wing markings of Hemopsis were very similar to that of Ategumia and Mecyna in the tribe Nomophilini. Meanwhile, in Hemopsis, the reduced uncus, tongue-shaped valva, fibula directed toward sacculus, multiple cornuti, strongly sclerotized colliculum, slightly sclerotized antrum, and a transverse or longitudinal elongate signum are all consistent with the characteristics of the tribe Nomophilini. Therefore, we place the genus Hemopsis in the tribe Nomophilini.
Two subspecies of Ategumiaadipalis (Lederer, 1863), A.a.kwantungialis (Caradja, 1925) and A.a.nigromarginalis (Caradja, 1925), are very similar to Hemopsis species in appearance. Based on the original descriptions and type specimen photos of these two subspecies, we found A.a.kwantungialis was nearly identical with Hemopsisnr.dissipatalis of Matsui et al. (2022) in appearance. Moreover, according to our examination of Ategumiaadipalis and description by Kirti and Rose (1986), we do not think that A.a.kwantungialis is a subspecies of A.adipalis. Furthermore, we found that the lectotype specimen (MNHGA 177.705) of A.a.nigromarginalis was externally similar to H.dissipatalis and had some inconspicuous difference in wing markings, the allolectotype specimen (MNHGA 177.706) was externally similar to H.abstracta sp. nov. and had some inconspicuous difference in wing markings, and the paralectotype specimen (MNHGA 177.707) was more similar to H.coalita sp. nov. and H.heteroidea sp. nov. in appearance than to A.adipalis. Considering these observations and the original descriptions, we think that A.a.nigromarginalis is incorrectly associated as a subspecies of A.adipalis and that it may be misplaced in the genus Ategumia and may belong to Hemopsis instead. Therefore, further studies of these species and subspecies are needed to elucidate their generic placement and relationships among them.
