## TL;DR

This paper describes a new species of longhorn beetle from China and provides a revised key to identify the four species in the genus Trichorondonia.

## Contribution

The discovery and description of a new species, Trichorondonia wenkaii, and the first description of the male of T. kabateki.

## Key findings

- A new species, Trichorondonia wenkaii, was identified and described from China.
- The male of Trichorondonia kabateki was described for the first time with a new locality record in Hubei province.
- Diagnostic features distinguishing the new species from others in the genus were detailed.

## Abstract

The genus Trichorondonia Breuning, 1965 currently comprises three species. The type species, Trichorondonia hybolasioides Breuning, 1965, is distributed in Laos and China. The other two species, Trichorondonia pilosipes (Pic, 1907) and Trichorondonia kabateki Viktora, 2024, are both endemic to China. This paper provides a brief revision of the genus and describes a new species: Trichorondonia wenkaii sp. nov. Additionally, the male of Trichorondonia kabateki is described for the first time with the new locality record, and a key to the four species is provided.

This paper provides a brief review of the genus Trichorondonia Breuning, 1965. A new species, Trichorondonia wenkaii sp. nov. (文凯毛郎氏天牛), is described and illustrated. Trichorondonia kabateki Viktora, 2024 is newly recorded in Hubei province, with the first description of the male. Additionally, photographs of the holotypes of three previously described species are presented. A key to the four species is given. The new species differs from T. pilosipes and T. hybolasioides in having elytra with rounded lateral apical angles and a vertex with blackish-brown pubescence medially behind the eyes. The new species can also be easily distinguished from T. kabateki by the antennae being ventrally fringed with sparse hairs only on segments 1–8, the greyish-yellow pubescence on the pronotum being unevenly distributed and particularly sparse in the posterior half, the elytra having rather thin greyish-yellow pubescence and hardly visible greyish-white pubescence, elongated blackish-brown spots on the elytral longitudinal carinae, and a small tuft of black setae at the centre of the elytral base where there is no obvious tubercle. The type specimen of the new species was collected in Dianping village, Xinhua town, Leye county, Guangxi Zhuang Autonomous Region of China, and deposited at Insect Collection, College of Agriculture, Yangtze University, Jingzhou, Hubei, China (ICYZU).
