Male
  • Both sexes are easily recognized by the presence of two equal, well-separated spurs on coxa I
  • The male features a smooth and shiny scutum with a few scattered, large punctations, unfused festoons, and lacks both lateral grooves and a caudal depression
  • Ventrally, it possesses very large adanal shields, whereas the subanal shields are very small or sometimes entirely absent
  • While the overall size range is variable (with Afghan specimens being the smallest noted), most specimens are comparatively large.
