Diagnosis

Body oval, TL = 4.27–6.12 mm (5.41 ± 0.59 mm, n = 9) and clypeus with marginal bead very fine and complete across apex. Mycomystes nigriventris resembles its Mexican congener M. ferrugineus in the oval body shape and dilated tibiae. It differs in the black ventral colouration (yellowish to reddish-brown in M. ferrugineus ), elytral punctation with rows of punctures uniformly longitudinal and not confluent (in M. ferrugineus these punctures are more irregular and confluent at disc), the lack of a conspicuous angle at the outer side of protibiae (present in M. ferrugineus ) and the occurrence in the southern portion of the neotropics (while M. ferrugineus occurs in the northern portion). Male genitalia with head of penile flagellum horseshoe-shaped, with the anterior borders only shallowly fused medially. Female genitalia with vaginal process present, narrowed and elongate to the level of gonostyli.

Distribution

South and Southeast Brazil ( Figure 55 View Figure 55 ).

Natural history

Mycomystes nigriventris was recorded once in association with Pleurotus sp. ( Pleurotaceae ) (Pecci-Maddalena and Lopes-Andrade 2020).
