description: Adelopsis grouvellei Jeannel, 1936
(Figs. 152–163)
Adelopsis grouvellei Jeannel, 1936: 66 [and Figs. 90–91]; Szymczakowski, 1963: 671 (redescription—but see Taxonomic Notes) (holotype and “ paratype ” seen); Gnaspini, 1996: 539 (types seen); Salgado, 2010: 213 (assignment to group).
Note: see Taxonomic Notes for erroneous/doubtfull citations of this species.
Type material examined: Holotype male [a single specimen of the type locality in original description, assumed as holotype] in MNHN (Gnaspini, 1996: 541). Labels: “ Bahia, Brésil (tabacs) / A. Grouvelle, 1913”.
One additional female also labeled “ type ” in BMNH [listed under examined material in Jeannel, 1936, but not as type] (Gnaspini, 1996: 541). Labels: “ Rio de Janeiro, Brazil / C. Darwin / Darwin coll. 1885-119 / Rio—8?9” [there is possibly a number between 8 and 9, but it is where the pin hole is placed]. Note: Because this female is from a different locality, it is not possible to be sure that it belongs in the same species, and this should be considered a doubtful record. Both specimens here illustrated.
Length: 3.0 mm (original description); 2.25 mm (male) and 2.0 mm (female, doubtful record) (our measurement). Note: our measurement highly differs from that in the original description.
Type locality: “ Bahia (collected in Paris on tobacco from Bahia)”, Brazil.
Additional material examined (misidentification): 3 males (Szymczakowski det., 1963: 671 [and Figs. 10–13]— Brazil: São Paulo: São Paulo) in NMPC (Gnaspini, 1996: 541)—they belong in two different species (Gnaspini, 1996: 540), here described as Adelopsis mrazi sp. n. and Adelopsis waclawi sp. n.
Taxonomic Notes.
1) Szymczakowski (1963: 671) analysed the holotype and what he called a paratype (possibly the doubtful female “type” listed above), and three additional males from São Paulo [his Figs. 10–12 (one specimen) and 13 (a different specimen). The São Paulo records are here recognized as two different species (A. mrazi sp. n. and A. waclawi sp. n. see above), but we could not relate either of them to Szymczakowski (1963) figures. Therefore, Szymczakowski (1963: 671) citation for A. grouvellei is partly right (holotype seen) and partly in error. Yet, Szymczakowski (1963) gave a redescription of the species, based on all specimens he examined (i.e., based on [at least] three different species); therefore, it is not possible to recognize which part could be used as description of A. grouvellei.
2) Szymczakowski (1970: 329 [and Fig. 1]) recorded this species in Paraná State, Brazil, and comments (as he did in 1963) that the tip of the aedeagus of this species is very variable, what we here recognize actually to be different species. Unfortunately, we could not relate Szymczakowski (1970) figures to a species, and not even to his 1963 figures (see previous note), and we did not have access to the material he examined. Therefore, this record should be considered at least to be doubtful, but it is probably erroneous (especially because of the large distance from the “ type locality”).
3) Salgado (2005: 969 [and Figs. 18–19], 2015: 33) 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. 18) fits any species in the subgroup grouvellei here established. The spermatheca illustrated (his Fig. 19) is complex enough to possibly allow recognition of species, but differs from all spermatheca described so far. Yet, this record is distant 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. asperoides and A. luculenta (both recorded for the first time in Santa Catarina also by Salgado, 2005), and A. aspera, recorded by Jeannel (1936) based on a female, all with types from São Paulo and here considered doubtful records (see Taxonomic Note at 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. Data on wings not observed [apterous, according to original description (key couplet)]. Male ventrites with a pair of posterior projections. Apex of the right lobe of the aedeagus as an upsidedown trapezoid, with the apical margin curved outward and bearing a row of small tubercles (Figs. 154, 155), with a sinuate margin ending bluntly, in lateral view (Fig. 152). Flagellum shorter (about 3/ 4 in length) than aedeagus, strongly curved, almost forming a 1-turn coil (Fig. 152). Proportion aedeagus/elytron = 0.32. Spiculum gastrale of the genital segment divided at apex, with long branches (Fig. 158). Male mesotibia regularly curved internally (Fig. 161).
The doubtful record female has a spermatheca with many narrow turns followed by a short and curved body ending in a rounded apical bulb (Fig. 163). Proportion spermatheca/elytron = 0.13.
Distribution. Brazil: Bahia (original description; Szymczakowski, 1963; here),
Note: Doubtfull and Erroneous records (see Taxonomic Notes above): Brazil: Paraná (Szymczakowski, 1970), Rio de Janeiro (original description; Szymczakowski, 1963), Santa Catarina (Salgado, 2005, 2015), and São Paulo (Szymczakowski, 1963) States.
Taxonomic Remarks. The lateral view of the aedeagus (Fig. 152), together with the frontal view of the tip of the right lobe of the aedeagus (Fig. 155, which shows the diagnostic ‘tubercles’ along the apical margin of the right lobe), seems to help in the recognition of this species.
