One new species of Bundoksia Lucañas, 2021 from China is described. We construct a haplotype network from 21 COI sequences to display the relationships amongst populations of Bundoksia longissima sp. nov., mainly from Hainan Island, Yunnan Province and Guangxi Province, China. For the first time, we provide the details of female genitalia in addition to the known external morphology and male genitalia of the genus. Six molecular markers (12S, 16S, 18S, 28S, COI and COII) from a total of 38 samples, including three samples of Bundoksia longissima sp. nov., are used to reconstruct phylogenetic trees using Maximum Likelihood (ML) and Bayesian Inference (BI) to assess the phylogenetic affinities of Bundoksia. Photographs of the morphology and a key to the three Bundoksia species are also provided.

Bundoksia longissima sp. nov.

Diagnosis: Bundoksia longissima sp. nov., differs from the two known species, B. rufocercata (Shelford, 1911) and B. sibuyania Lucañas, 2021 by the following characteristics: 1) pronotum: with slightly thickened lateral margin; 2) mid- and hind- femur with only distal spines on ventral margin; 3) the first abdominal tergite unspecialised. In addition, Bundoksia longissima sp. nov. can be distinguished from B. rufocercata as follows: pronotum black and female tegmina triangular in the former, whereas pronotum with yellow orange marking and female tegmina quadrate in B. rufocercata.
Etymology: The scientific epithet is derived from the Latin word longissimus, referring to the long and narrow body.

Ecology: According to our collecting information, Bundoksia longissima is active at night to forage and mate. It is distributed mainly on tree trunks, a few on leaves (Fig. 4). Once frightened, the female will emit an acidic liquid (lemon smell), whose specific components have not been analysed.
