摘要
摘要描述了贵州省北部遵义市近郊区黑洞石灰岩岩洞的Casaleaphaenops liyunchuni n. gen.， n. sp.和黔西攀州子木洞岩洞的Panaphaenops guixicus n. gen.， n. sp.两个新属和新种。Casaleaphaenops n. geng具有显著的变异，具有非常细长的身体和薄薄的附属物，但前凸短且明显凸出;特别是，鞘翅的每一个肱骨角都格外地向上突出，就像一根锋利的脊椎，这种特征只有在意大利trechine Italaphaenops物种中才知道，尽管它们更小更瘦。Panaphaenops n. gen也是一种aphaenopses，尽管它与Aspidaphaenops u， 2006和Tianeotrechus Tian & Tang, 2016有一定的关系，但其在Trechini中的系统发育位置仍然未知。
Two remarkable new genera and species of cavernicolous ground beetles from Guizhou Province, southwestern China (Coleoptera: Carabidae: Trechinae)
Summary Two new genera and two new species of troglobitic trechine beetles are described and illustrated: Casaleaphaenops liyunchuni n. gen., n. sp. from the limestone cave Hei Dong in the suburb of Zunyi City, northern Guizhou Province, and Panaphaenops guixicus n. gen., n. sp. from the cave Zimu Dong in Panzhou, western Guizhou. Casaleaphaenops n. gen. is remarkably modified, with a very elongated body and thin appendages, but pronotum short and markedly convex; in particular, each humeral angle of elytra extraordinarily protruding upwardly as a sharp spine, a character only known in Italian trechine Italaphaenops species though smaller and thinner. Panaphaenops n. gen. is also an aphaenopsian, remaining unknown for its phylogenetical position in Trechini though it is somewhat related to Aspidaphaenops Uéno, 2006 and Tianeotrechus Tian & Tang, 2016.
