A new genus and two new species of Pterostichini from China, with “sphodrine-like” parameres (Coleoptera, Carabidae)

Abstract

These two species share a unique combination of characters, not known in any other Pterostichini. The new genus can be distinguished by having (1) a left paramere without transverse apophysis; (2) a falcate right paramere, with styloid apex, broadened medial part and subbasal hasp; (3) a median lobe with dorsal ostium; (4) metatarsomeres 1-2 setose on the medioventral surface, in addition to the lateroventral setae; (5) meso-and metatarsomeres 1-4 with two dorsolateral grooves diverging distally; and (6) elytral striae with shining isodiametric microreticulation, which is in contrast to less shining transversemesh microreticulation on the elytral intervals.

“…In comparison, faunistic studies on the country's ground beetle fauna are rare. Bosnian carabid material is occasionally considered in the context of revisions (e. g. Jaeger 2007;Guéorguiev & Lohaj 2008;Bonavita & Vigna Taglianti 2010) and there are frequent descriptions of new species from caves (Ćurčić et al 2012;Lohaj & Mlejnek 2012;Quéinnec & Ollivier 2021). Some papers also deal with the distribution of individual species within the genus Carabus (e. g. Jambrošić Vladić et al 2018;Rapuzzi & Kleinfeld 2018;Kulijer et al 2019).…”
