( Figs. 128–136 )

Adelopsis insolitus Szymczakowski, 1961: 144 [and Figs. 8–10 ]; Salgado, 2005: 963.

Adelopsis insolita ; Gnaspini, 1996: 539 (holotype seen; spelling corrected to feminine gender); Salgado, 2005: 971 [and Fig. 20 ], 2010: 213 (assignment to group).

Type material examined: Holotype male in NHRS (Gnaspini, 1996: 541). Labels: “Sta Catharina / Nova Teutonia / Brasil. /5.1938 / Fr. Plaumann ”. Specimen here illustrated.

Length: 2.0 mm (original description); 2.05 mm (our measurement).

Type locality: Nova Teutônia , Santa Catarina State, Brazil .

Short Redescription. Eyes seem slightly reduced ( Fig. 133 ). Winged [differing from original description, as apterous]. Arm of the right lobe of the aedeagus elongate, with apex bent internally ( Fig. 131 ). Proportion aedeagus/ elytron = 0.40, considerably large in comparison with other species in the genus. Spiculum gastrale of the genital segment with a very short and wide base, with an almost straight margin, and divided at apex, with long branches ( Fig. 132 ). Male mesotibia regularly curved internally ( Fig. 135 ). Female unknown.

Distribution. Brazil: Santa Catarina State: known only from vicinity of type locality (original description; Salgado, 2005; here).

Taxonomic Remarks. The lateral view of the aedeagus ( Fig. 130 , with a prolonged projection, also seen in Fig. 10 in Szymczakowski, 1961), together with the frontal view of the tip of the right lobe of the aedeagus ( Fig. 131 ), seems to help in the recognition of this species, as well as a slightly reduced eye. Although our figures of the aedeagus are somewhat confusing because we did not add many details, we understand they are still useful for species recognition.
