Schistoneurus paraimpressus Jaschhof, 2024, sp. nov.

Schistoneurus paraimpressus sp. nov. urn:lsid:zoobank.org:act: 812EC0F3-671B-40BA-B0A9-39D077CCAC0D Fig. 29 Differential diagnosis Morphology In terms of male morphology, S. paraimpressus sp. nov. bears a close resemblance to S. impressus (Jaschhof & Jaschhof 2013: fig. 119), the very few differences in terminalia structures being as follows. In the new species, the gonocoxal ventral emargination is markedly shallower, resembling the shape of a watch glass (↓ 1, Fig. 29A); each of the parameres ends in a single small knob (↓ 2, Fig. 29A) rather than in several knobs of various sizes; and the gonostylus is slightly more elongate and more slender, and has a larger area covered by thick black spines, especially along the inner margin (↓ 3, Fig. 29B). Also, in S. impressus the gonostylar inside has a transverse ridge, which in S. paraimpressus is absent so that the inner surface is fairly evenly concave (↓ 4, Fig. 29B). Larvae and females of the new species are unknown. DNA barcode CO1 sequences (651‒653bp) of the type specimens are available in BIN BOLD:AEO6710.

Etymology The name ‒ the Latin prefix ‘ para -’ means ‘beside’ ‒ refers to the resemblance of this species to S. impressus.
