Material examined

Syntypes BRAZIL • 1 ♀; Mato Grosso do Sul, Corumbá, Urucum ; [-19.200684, -57.599997]; 20 Oct. 1900; A. Borelli leg.; USNM 2021 .

Distribution

Comments

According to Sierwald & Reft (2004), the type material of some species described by Silvestri is deposited in American and European museums. In subsequent works, not one reference was made for Pseudonannolene brevis or in which museum its types were supposedly deposited (see Viggiani 1973). The male syntypes of P. brevis described by ( Silvestri 1902) were not found, but through consultations and visits made to some museums one female syntype was found and examined (USNM 2021; see article #73, ICZN) ( Fig. 161 ). The original description of P. brevis does not provide illustrations or diagnostic features for the species. Nonetheless, the species clearly belongs to Pseudonannolene by having the longitudinal suture on promentum ( Fig. 176C ).
