Material examined

Holotype FRENCH GUIANA • ♀ [fragmented]; Cayenne ; [4.936964, -52.312784]; ISNB.

Distribution

Known only from the type locality Cayenne, French Guiana ( Fig. 187 ).

Comments

Pseudonannolene rugosetta was described by Silvestri (1897d) based on an adult female apparently collected in French Guiana. Mauriès (1987) examined this holotype, confirming its generic position but questioning the doubtful location from the northernmost region of the Amazon basin. To date, this is the northernmost record of the genus, with the closer occurrence only by the troglobitic species P. spelaea from Pará State, Brazil. The female holotype of P. rugosetta is not sufficiently distinguished from all congeners ( Fig. 162 ). Nonetheless, the species clearly belongs to Pseudonannolene by having the longitudinal suture on promentum ( Fig. 176E ).
