description: Adelopsis luculenta Szymczakowski, 1963
(Figs. 190–195)
Adelopsis luculentus Szymczakowski, 1963: 673 [and Figs. 14–17].
Adelopsis luculenta; Gnaspini, 1996: 539 (holotype seen; spelling corrected to feminine gender); Salgado, 2010: 213 (assignment to group).
Note: see Taxonomic Note for erroneous/doubtfull citations of this species.
Type material examined: Holotype male in NMPC (Gnaspini, 1996: 541). Labels: “ São Paulo / Bras. Mráz lgt. / Mus. Pragense”. Note: the specimen was previously dissected, and the genital segment was missing. Specimen here illustrated.
Length: 3.7 mm (original description and our measurement). It is a very large size when compared to other species in the genus.
Type locality: São Paulo, [São Paulo State], Brazil.
Taxonomic Note. Salgado (2005: 971 [and Figs. 21–22], 2015: 34) recorded this species from Santa Catarina State, Brazil. Unfortunately, he did not illustrate the aedeagus (which is “mandatory” for the proper recognition of species in Adelopsis) and the genital segment illustrated (his Fig. 21) fits any species in the subgroup grouvellei here established. The spermatheca illustrated (his Fig. 22) is a 2-turns spermatheca, common to several species of the genus (as can be seen in several species here illustrated). Salgado (2005) recorded size range as ‘2.60–3.70 mm’, the latter being exactly the size recorded in the original description; however, he did not state if this measurement was taken from the specimens he had at hand or from the original description—in other words, it is not possible to know if he had specimens as large as the holotype (which seems to be a diagnostic feature of the species) or not. Yet, this record is far from the “type locality”, and other species occur in the area. Therefore, this record from Santa Catarina should, at least, be considered doubtfull. Other species of the subgroup grouvellei nov. recorded in Santa Catarina are A. grouvellei (type from Bahia) and A. asperoides (type from São Paulo) (both recorded for the first time in Santa Catarina also by Salgado, 2005), and A. aspera (type from São Paulo), recorded by Jeannel (1936) based on a female, all here considered doubtful records (see Taxonomic Note for each species). On the other hand, A. triangulifer is indeed recorded in both Santa Catarina and São Paulo States, based on the similarities of the aedeagus and genital segments based on illustrations, reinforcing the need for illustrating these features from several views, which was not done for the species cited in the previous phrase.
Short Redescription. Eyes normal. Winged. (It seems to have) No posterior projections on male ventrites. Right lobe of the aedeagus with a long arm and apex as an upside-down trapezoid with the apical margin straight (Figs. 191, 193), with a curved margin ending bluntly, in lateral view (Figs. 190, 192). Flagellum almost as long as aedeagus, strongly curved and projected laterally, forming a tape-shaped 1-turn coil (Fig. 190). Proportion aedeagus/ elytron = 0.24. Genital segment missing.
Female originally unknown. Salgado (2005) recorded this species from Santa Catarina, here considered a doubtful record, illustrating the spermatheca (his Fig. 22).
Distribution. Brazil: São Paulo State (original description; here).
Note: Doubtfull records (see Taxonomic Notes above): Santa Catarina State (Salgado, 2005, 2015).
Taxonomic Remarks.
1) The lateral view of the aedeagus (Figs. 190, 192), together with the frontal view of the tip of the right lobe of the aedeagus (Figs. 191, 192), seems to help in the recognition of this species.
The original illustration of the aedeagus (Szymczakowski, 1963: Fig. 17) is somewhat confusing because he did not highlight the presence of a coiled tape-shaped flagellum, but the axis of the flagellum is highlighted and resembles our figures.
This species is also distinctive by its large size when compared to other species in the genus and by the pointy tip of the antenna (Fig. 194), which has been rarely recorded in the genus (especially when the group benardi is considered).
2) This species is tentatively assigned to subgroup, since the genital segment (which is here considered important for subgroup assignment) is unknown.
