Species groups

The genus currently includes the following species groups, at least 25 of which are known from China:[3]

  • Hercostomus abnormis group – China
  • Hercostomus absimilis group[4][5] – China
  • Hercostomus albidipes group – China
  • Hercostomus apiculatus group[6] – China
  • Hercostomus baishanzuensis group[7] – China
  • Hercostomus biancistrus group[6] – China
  • Hercostomus crassivena group[8] – China
  • Hercostomus curvus group[9] – China
  • Hercostomus cyaneculus group – China
  • Hercostomus digitatus group – China
  • Hercostomus digitiformis group[4] – China
  • Hercostomus fatuus group[10] – China
  • Hercostomus flavimaculatus group[9] – China
  • Hercostomus flaviventris group – China
  • Hercostomus fluvius group[9] – China
  • Hercostomus hamatus group[11] – China(?)
  • Hercostomus incisus group[9][12] – China
  • Hercostomus intactus group – China
  • Hercostomus longicercus group[9] – China
  • Hercostomus longus group – China
  • Hercostomus nanlingensis group[13] – China
  • Hercostomus plagiatus group[14] – Palearctic
  • Hercostomus prolongatus group[9] – China
  • Hercostomus quadriseta group[6] – China
  • Hercostomus shennongjiensis group[9] – China(?)
  • Hercostomus subnovus group[9] – China
  • Hercostomus takagii group – China
  • Hercostomus ulrichi group[15][3] – China

The Palearctic species of Hercostomus are traditionally separated into five numbered groups, based on the coloration of the femora, postocular setae and antennae:[2]

  • Group I: Femora yellow; lower postocular setae yellow or white; antennae partly yellow
  • Group II: Femora yellow; lower postocular setae yellow or white; antennae black
  • Group III: Femora yellow; lower postocular setae black
  • Group IV: Femora black; lower postocular setae yellow or white
  • Group V: Femora black; lower postocular setae black

In 1999, Igor Grichanov divided the Afrotropical species of Hercostomus into three numbered groups.[16] Two of these have since been separated into their own genera:[17]
