Wang, Han-Qiang & Liu, Xian-Wei, 2020, A new genus and a new species of Anabropsinae (Orthoptera: Anostostomatidae) from China, Zootaxa 4809 (3), pp. 509-520 : 511

Genus Melanabropsis gen. nov. ḢDǿḁ

Generic diagnosis: Body size medium to large, dorsal surface glabrous and shining black. Fastigium of vertex narrow, more than half the width of the first antennal segment, without longitudinal furrow above ( Fig. 2D ). Occiput without longitudinal carina, but bearing indistinct suture in the middle. Disc of pronotum without flattened hind part, also with central sulcus, humeral sinus absent ( Figs. 2A, B ; 3A, B ). Prosternum unarmed, meso- and metasternum with widely rounded tubercular lobes ( Figs. 2F ; 3G ). Tegmen and wings reduced or absent ( Figs. 2E ; 3F ; 5 ). Fore and mid coxae with a spine, all femora unarmed; fore tibiae without tympana ( Figs. 2A ; 3E ); fore and mid tibiae armed with spurs, dorsal spine of fore tibiae ranging from several to none; hind tibiae with spines on the outside and inside. Male 9 th abdominal tergite protruded as a short broad lobe in central posterior margin, 10 th abdominal with a pair of distinct barbs, the area between these barbs slightly produced caudally. Male paraprocts elongate and upcurved; cerci simple; subgenital plate thick with a pair of large and swollen styli, narrowly separated ( Fig. 2G ~L). Female with well developed ovipositor, curved upwards and arcuate, with smooth margins ( Fig. 3I ).

Type species: Melanabropsis tianmuica sp. nov., here designated.

Included species: type species, Anabropsis yanbarensis , Apteranabropsis genetrix and Apteranabropsis murayamai .

Remarks: This new genus is closely related to Paterdecolyus , but differs from the latter and all the other Anabropsini by the unarmed sterna, absence of tibial tympana and characteristic styli. The new genus also shares unarmed sterna with genera of Brachyporini , but differences in male genital characters especially the 10 th abdominal tergite are significant.

Etymology: The generic name from mela plus an affix derived from generic name Anabropsis refers to its glossy black color.
