H. quadripicta species group

This group comprises six species ( H. brevis , H. brunnifacialis , H. knighti , H. quadripicta , H. sandakanensis and H. singaporensis ) with the following combination of characters: vertex and thorax dorsally yellow; pronotum, mesonotum and scutellum with one small brown spot laterally; forewing veins brown, more heavily marked with brown on some veins including a spot on apex of claval veins, on veins of fifth apical cell and on apical cells and on wing apex; vertex smooth or with indistinct longitudinal or oblique striations; pronotum smooth or with indistinct transverse striations; aedeagus separated from connective, without preatrium and with long basal apodeme with side lobes, shaft elongate, cylindrical, with or without processes. One species tentatively included in the group ( H. brevis ) has similar markings to other species but its connective is distinctly different.
