Anisophlugis Chamorro-Rengifo & Olivier   n. gen.

( Figs. 1–6 View FIGURE 1 View FIGURE 2 View FIGURE 3 View FIGURE 4 View FIGURE 5 View FIGURE 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 View FIGURE 1 A, B and 2A, B). Males with asymmetric mandibles ( Fig. 1 View FIGURE 1 C) and female with symmetric mandibles ( Fig. 2 View FIGURE 2 C). Tegmina almost totally covered by the pronotum ( Figs. 1 View FIGURE 1 D, E and 2D, E). Male cerci simple, devoid of ramifications ( Figs. 3 View FIGURE 3 A and B). Male epiproct bilobed and elongated, paraprocts elongated ( Figs. 3 View FIGURE 3 B and C). Male subgenital plate elongated with long true styli ( Fig. 3 View FIGURE 3 D). Female subgenital plate with an appendix at apex ( Figs. 2 View FIGURE 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.
