Diagnosis. Helopinina can be distinguished from other subtribes of Pedinini by the following characteristics ( KamiŃski et al. 2019a, 2021): supraorbital crest flat (carinated in Leichenina); antennae elongate (short in Leichenina); eyes not covered with scales (covered with scales in Leichenina); the basal margin of mentum wide and shiny (narrow and dull in Pedinina ); epistomal margin near maxillary fossa fold-like (flat in Pedinina ); metanepisternum triangular (rectangular in Pedinina ); abdominal process equal to or wider than hind coxae (narrower than hind coxae in Pedinina ).

From the remaining tribes of the opatrinoid clade ( KamiŃski et al. 2019a, 2021), Helopinina differs by having gula smooth or covered with irregular rugosities (with stridulatory surface in Platynotini ), mentum with lateral wings visible (mentum flat covering the wings in Dendarini), and protrochanter without elongate base (with elongate base in Opatrini ).

Taxonomic Diversity (13 genera, 239 species). Amatodes (33 spp.), Ametrocera (4), Anaxius (7), Aptila (4), Asidodema (3), Blastarnodes (6), Diestecopus (26), Drosochrus (40), Micrantereus (75), Nicandra (32), Oncopteryx (1), Piscicula (1), Psectes (7).

Distribution. Africa and Arabian Peninsula ( Figs. 5 , 6 ).
