Paraneanias gen. nov.

Figs. 98

Type species: Paraneanias striatus sp. nov.

Diagnosis. The general habitus of the new genus is similar to Neanias and Monseremus , the latter genus is also apterous. It differs from Neanias by the complete absence of wings while Neanias still has small remnants of wings. From Monseremus it differs by the simple shape of the subgenital plate that is greatly modified in Monseremus while Paraneanias gen. nov. has the apex of the seventh sternite modified. From both genera, Paraneanias differs further by the lower number of only three pairs of spines on fore and mid tibiae plus one pair of apical spurs and by the absence of a ventral pre-apical spine on the hind tibiae. This situation resembles the situation in Papuogryllacris and related genera and differs from most other genera of Gryllacrididae . Moreover, the tibial spines are rather small. The hind femora are very thick and have the narrow apical area greatly reduced. The ovipositor is straight has a bend just behind base. From Papuoneanias the new genus differs by the complete absence of wings and the short and strongly thickened hind femora and from Papuoneanias , which is only known from a male, by the complete absence of wings. Details of general morphology are as described under the type species.

Included species. So far only known from the type species, P. striatus sp. nov. Etymology. The name of the new genus is built from Neanias adding the prefix para, referring to the superficial similarity to that genus.
