Adelopsis brasiliensis Jeannel, 1936

( Figs. 26–27 )

Adelopsis brasiliensis Jeannel, 1936: 66 [and Figs. 75–76 ]; Gnaspini, 1996: 539 (type seen); Gnaspini and Peck, 2001: 429 (tentative assignment to group ascutellaris); Salgado, 2010: 214 (assignment to group capitanea). Here returned to group ascutellaris.

Type material examined: Holotype male [a single specimen in original description, assumed as holotype] in MNHN ( Gnaspini , 1996: 541). Labels : “Blumenau / S.O. [sud oeste = southwestern; but actually southern] Brasilien / (Reitter)” // “ Ptomaphagus braziliensis n. sp. ”. Note: the specimen was previously dissected, and both aedeagus and genital segment were missing [see Note under MNHN, in ‘Methods and Materials’]. Specimen here illustrated.

Length: 3.5 mm (original description); 3.15 mm (our measurement). It has a large size when compared to other species in the genus.

Type locality: Blumenau , Santa Catarina State, Brazil .

Short Redescription. Eyes normal, but slightly less than the usual height ( Fig. 26 ). Winged. No posterior projections on male ventrites. Aedeagus and genital segment missing. Female unknown.

Distribution. Brazil: Santa Catarina State: known only from type locality (original description; here).

Taxonomic Remarks.

1) Unfortunately, both aedeagus and genital segment of the specimen examined were missing, not allowing a proper recognition of the species, even using illustrations in Jeannel (1936: Figs. 75–76 ). The aedeagus seems similar to that of other species in the group (see also Taxonomic Remarks under Adelopsis ascutellaris , above). However, the species is very large when compared to other species in the group. It is from a locality where it is the only species of the group recorded so far, except for A. curvipes Salgado, 2005 (length 2.75 mm), from a close locality. Therefore, we prefer to keep it as a separate species, and, in the future, compare it to the type of A. curvipes , to check for synonymy.

2) This species is tentatively assigned to subgroup, since the genital segment (which is here considered important for subgroup assignment) is unknown.
