Adelopsis bruchi ( Pic, 1926)  

( Figs. 196–208 View FIGURES 196–208 )

Ptomaphagus bruchi Pic, 1926: 1   .

Adelopsis bruchi   ; Jeannel, 1936: 66 [and Figs. 73–74 View FIGURES 62–75 ] (combination not stated as taxonomic change, because he did not mention the species was not described under Adelopsis   ) (type seen); Gnaspini, 1996: 539 (types seen); Salgado, 2010: 213 (assignment to group benardi). Here assigned to group bruchi nov.

Type material examined: 2 “ type ” males and 1 “ type ” female in MNHN and 3 “ type ” specimens in MACN (Gnaspini, 1996: 541); assumed as syntypes—sex and number of specimens not given in original description, but referred to Bruch and Pic collections [but Jeannel, 1936 referred to only “ 1 male, in Pic collection”]. Labels [ MNHN specimens]: “R. Argentine / Prov. B. Ayres / C. Bruch ” // “ Ptomaphagus bruchi   ” // “Jeannel vidit”. Additional 1 male and 1 female attached to the same pin with same data added of date “ 9.vii.1923 ”. All 3 MNHN specimens as well as one type male from MACN here illustrated   .

For taxonomic reasons, the MNHN male “type” singly attached to a pin is here designated as lectotype; and the remaining specimens as paralectotypes.

Length: 2.5 mm (original description); 2.8 mm ( Jeannel, 1936); 2.3 mm (our measurement, all 3 MNHN specimens).

Type locality: “ Argentina ” [ Jeannel, 1936 added “ Buenos Aires ”]   .

Additional material examined: 24 specimens in MACN (Gnaspini, 1996: 541). Labels: “ Prov. B. Aires / 09 vii 1923 / C. Bruch ”   .

Short Redescription. Eyes normal. Winged. Male ventrites with a pair of posterior projections.Apex of the right lobe of the aedeagus seemingly subquadrate in dorsal or ventral views ( Figs. 203, 205 View FIGURES 196–208 ), but clearly pointy, subtriangular in frontal view ( Fig. 196 View FIGURES 196–208 ), and pointy in lateral view ( Figs. 202, 204 View FIGURES 196–208 ). Flagellum thick and shorter (about 1/ 3 in length) than aedeagus, with a bent apex ( Fig. 203 View FIGURES 196–208 ). Proportion aedeagus/elytron = 0.27. Spiculum gastrale of the genital segment divided at apex, with long branches ( Fig. 206 View FIGURES 196–208 ). Male mesotibia curved, slightly bent internally ( Fig. 201 View FIGURES 196–208 ). Spermatheca with 3-turns placed close to the spermatheca base, followed by a short and curved body ending in a sharp curve before the elongate apical bulb ( Figs. 207, 208 View FIGURES 196–208 ). Proportion spermatheca/elytron = 0.12.

Distribution. Argentina: Buenos Aires Province: known only from type locality (from type labels [incomplete data in original description]; Jeannel, 1936; here).

Taxonomic Remarks. The pointy aedeagus in lateral view ( Figs. 202, 204 View FIGURES 196–208 ), together with the frontal view of the tip of the right lobe of the aedeagus ( Figs. 196, 203 View FIGURES 196–208 ), seems to help in the recognition of this species.

This species is another good example to show the need to illustrate as many views of the aedeagus as possible. For instance, the pointy nature of the apex of the right lobe of the aedeagus can be observed in frontal view of the apex ( Fig. 196 View FIGURES 196–208 ), but cannot be seen in dorsal view ( Fig. 203 View FIGURES 196–208 ), which is also different from Fig. 74 View FIGURES 62–75 in Jeannel (1936), illustrated with the adeagus slightly rocked towards its apex, in which the opening of the aedeagus appears deeper and the left lobe appears longer when compared to our Fig. 203 View FIGURES 196–208 .
