Taxonomy of the genus Duolandrevus Kirby, 1906 (Orthoptera: Gryllidae; Landrevinae) from China with a new species of the subgenus Eulandrevus Gorochov, 1988 Author Zheng, Yanna Author Ma, Libin College of Life Sciences, Shaanxi Normal University, Xi’an, China, 710119 text Zootaxa 2021 2021-03-12 4942 2 252 268 journal article 7589 10.11646/zootaxa.4942.2.7 6bedee85-2f44-4799-a7fe-d5ad1e141575 1175-5326 4600564 4B0F7A80-97E8-4C32-8228-0CA2B63F1601 Duolandrevus (Duolandrevus) bannanus Zhang, Liu & Shi, 2017 Duolandrevus (Duolandrevus) bannanus Zhang, et al., 2017: 590 Holotype information . Type locality: China , Yunnan , Xishuangbanna. Deposited at Museum of Hebei University ( MHBU ), Baoding , China (not examined). Remark. After observing some specimens of the six species of Eulandrevus , we found they have hind wings. But these are small and undeveloped (almost reaching posterior margin of metanotal gland), and entirely covered by the forewings. Therefore, we suggest other species of Eulandrevus might possess this feature. Regarding species of the subgenus Duolandrevus , their hind wings are conspicuously longer than metanotal gland, but the species D. (D.) bannanus which was originally placed in this subgenus does not possess this feature (whose hind wings not longer than metanotal gland).
