Type material examined

Lectotype, here designated: (RBINS, through photographs, Figure 4 View Figure 4 a-c): First label [red]: ‘TYPE’ [typeset with black border]. Second label [white]: ‘det. [typeset] Harold 1872 [unknown handwriting]/ Trox   /Borrei/Typ. Harold’ [Harold’s handwriting]. Third label [red]: ‘Coll. I. R. Sc. N. B./Uruguay: [typeset]/Montevidea/ex coll. de Borre [unknown handwriting]’. Paralectotype, here designated: (RBINS, through photographs): First label [orange, typeset]: ‘Para-/type’. Second label [white aged with green border]: ‘ Borrei / Har   ./ Montev. Ar.’ [unknown handwriting]. Third label [red]: ‘ Coll   . I   . R. Sc. N. B./ Uruguay: [typeset]/ Montevideo /ex col   . Candeze’   . Type locality: URUGUAY: Montevideo   .

Note: The type specimens of Trox borrei   cited by Scholtz (1990, p. 1418) as ‘holotype’ and ‘paratype’ are actually syntypes. When describing the species, Harold (1872) mentions one specimen from the collection of Preudhomme de Borre (without further indication of the location) and another specimen from the Candèze collection (from Montevideo), without distinguishing between primary and secondary types   . To avoid future confusion on this matter, and in order to keep a single name-bearing individual, we here designate the specimen considered as primary type by Scholtz (1990, p. 1418) as the lectotype.

Diagnosis

Omorgus borrei   is very similar to O. badeni   , from which it can be distinguished as discussed above. ( Figure 4 View Figure 4 a-b). For details of the morphology, see Vaurie (1962) and Scholtz (1990).

Geographic distribution

Here, we present the first record for Brazil based on five specimens, one from MS (Pantanal biome), another from RS (Pampa), and three others citing only ‘Matto Grosso’ as the collecting locality, which may refer to either MS, MT or RO ( Figure 9 View Figure 9 ). This species can also be found in Uruguay, Argentina and Bolivia (Scholtz 1990) as well as in Paraguay (Boquerón).
