Introduction
The typhlocybine leafhopper genus Anaka Dworakowska & Viraktamath, 1975 belonging to the tribe Dikraneurini was erected by Dworakowska and Viraktamath (1975) with Anakacolorata from India as the type species. Thapa and Sohi (1986) added A.nepalica and A.spinosa from Nepal. Dworakowska (1993) added A.blada (India), A.sumatrana (Indonesia), A.shashidhari (India), A.burmensis (Upper Burma), and A.roryi (China). Thus, eight species of the genus have been reported to date. Here, we review the previously known species and describe five new species, Anakaauricula sp. nov., Anakacruciata sp. nov., Anakacurvata sp. nov., Anakarosacea sp. nov. and Anakaspiralis sp. nov. from China. We also provide a key to males of all recognized species of the genus.
Material and methods
All specimens identified in this study were collected by net trapping in southern China and are housed at the Institute of Entomology, Guizhou University, Guiyang, Guizhou, P. R. China (GUGC:10657).
Dry specimens were used for preparing descriptions and illustrations. External morphology was observed under a stereoscopic microscope. Body length was measured with an ocular micrometer, in millimeters, from the apex of the head to the apex of the forewing in repose. The genital segments of the specimens examined were macerated in 10% NaOH, washed in water and transferred to glycerin. Male specimens were dissected under a MOTIC B1 SMS-168 SERIES microscope. Figures were made using an OLYMPUS CX41 compound microscope. Photographs were taken with Keyence VHX-1000 and an Olympus E-520 digital camera. The digital images were then imported into Adobe Photoshop CS6 for labeling and figure composition.
