Anisophlugis Chamorro-Rengifo & Olivier  n. gen.

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