Genus Glodianus Cameron, 1902

Glodianus Cameron 1902: 369 .

Type species: Glodianus bombycivorus Cameron, 1902 , by monotypy.

The genus Glodianus belongs to the small subtribe Glodianina comprising three exclusively Neotropical genera ( Townes 1970: 232, Yu et al. 2016). All species of the subtribe are characterized by a small, rectangular or slightly trapeziform areolet in the fore wing ( Fig. 5 ), polished first metasomal tergite ( Figs 6, 7 ) and ovipositor apex with oblique grooves on dorsal valve ( Fig. 9 ). Within the subtribe Glodianina , Glodianus is easily distinguished from two other genera by having a median compressed horn on the frons ( Fig. 2 ).

Glodianus comprises ten species distributed from Mexico to Venezuela and Brazil, including one species described in this paper and another one resurrected. Seven species of Glodianus are restricted to South America and three species are known only from Mexico. Nothing is known about the distribution of any species in Central America.

An identification key to all known species of Glodianus is provided. However, Townes (1970: 235) noted that the genus is large; Central and South American faunas of Glodianus require revision, therefore additional comparison of species with their original descriptions or types is strongly recommended. Two species, G. dimidiatus (Brullé) and G. xanthostomus Cameron , are known only from males, the type of the former species is lost, and original descriptions of both species are brief and incomplete. Thus, these two species cannot be distinguished from each other until the South American fauna of the genus is revised, and therefore both species are placed in one couplet of the key.
