Anisophlugis Chamorro-Rengifo & Olivier n. gen.

( Figs. 1–6 )

Etymology. The name is composed of the Greek prefix Aniso (άνισος) which refers to the asymmetric mandibles of males, and Phlugis , the name of the type genus of the tribe.

Type-species. Phlugiola appendicula Gorochov, 2015 , here designated.

Diagnosis description. Anisophlugis features the following combination of characteristics: Male and female brachypterous ( Figs. 1 A, B and 2A, B). Males with asymmetric mandibles ( Fig. 1 C) and female with symmetric mandibles ( Fig. 2 C). Tegmina almost totally covered by the pronotum ( Figs. 1 D, E and 2D, E). Male cerci simple, devoid of ramifications ( Figs. 3 A and B). Male epiproct bilobed and elongated, paraprocts elongated ( Figs. 3 B and C). Male subgenital plate elongated with long true styli ( Fig. 3 D). Female subgenital plate with an appendix at apex ( Figs. 2 F and G).

This new genus of Phlugidini differs from Cephalophlugis Gorochov, 1998 by larger head and pronotum in relation to body size. In Neophlugis Gorochov, 2012 there is a small and shallow concavity along the dorsomedial edges of the antennal cavities, and the male subgenital plate bears subapically located styli. In Odontophlugis Gorochov, 1998 the male cerci have teeth and hooks. In Paraphlugiola Cadena-Castañeda & Gorochov, 2014 the male subgenital plate has long pseudostyle projections. In Phlugiola Karny, 1907 males have simple epiprocts and paraprocts. In Phlugis Stål, 1861 the wings are well developed.

A comparison of characters across genera can be found in Table 1.
