Hyposoter bellus (Cresson, 1865) comb. nov.

Campoplex ? bellus Cresson, 1865: 44 .

Xanthocampoplex bellus Cresson, 1865 . Assigned by Townes and Townes (1966).

Holotype 3 (IES # 346) lacking wings; it is not a female as stated by previous workers. It is a very distinctive species as it is primarily yellow in colour with an inverted U-shaped black mark on the propodeum, and yellow spots on the mesoscutum, scutellum and anterodorsal part of the mesopleuron. Townes and Townes (1966) tentatively assigned it to Xanthocampoplex, presumably on the basis of its colour pattern. This species lacks any trace of a median ventral row of hairs characteristic of Xanthocampoplex, and has a more quadrate head than the very lenticular head characteristic of Old World Xanthocampolex. Although we cannot examine the wings we have no hesitation in placing this species in Hyposoter, where it resembles several other bright yellow Central American species.
