Adelopsis darwini Jeannel, 1936

( Figs. 220–222 )

Adelopsis darwini Jeannel, 1936: 66 ; Gnaspini, 1996: 539 (type seen). Type material examined: Holotype female [a single specimen in original description, assumed as holotype] in BMNH (Gnaspini, 1996: 541). Labels: “ Maldonado, Uruguay / C. Darwin // Darwin coll. 1885-119”. Specimen here illustrated.

Length: 3.0 mm (original description); 2.45 mm (our measurement).

Type locality: Maldonado, [Maldonado Department], Uruguay .

Short Redescription. Eyes normal. Winged. Female mesotibia curved ( Fig. 222 ). Spermatheca with 2-turns placed close to the spermatheca base, followed by a short body ending in a sharp curve before the elongate apical bulb ( Fig. 220 ). Proportion spermatheca/elytron = 0.10. Male unknown.

Distribution. Uruguay: Maldonado Department: known only from type locality (original description).

Taxonomic Remarks.

1) This species was not assigned to species group in Salgado (2010) (and kept here as not assigned) because it was based only on a female.

2) The specimen has a 2-turns spermatheca and a curved mesotibia, which fits in several species of Adelopsis . Therefore, although it is the only species recorded so far from Uruguay, we understand it should be considered a ‘nominal species’ (a species inquirenda), because it could probably not be recognized.
