Adelopsis brunnea Jeannel, 1936

Adelopsis brunneus Jeannel, 1936: 66 [and Figs. 86–87 ].

Adelopsis brunneus brunneus ; Szymczakowski, 1975: 15 [and Fig. 2 ] (type seen).

Adelopsis brunnea brunnea ; Gnaspini, 1996: 539 (spelling corrected to feminine gender); Gnaspini and Peck, 2001: 429 (assignment to group), 430.

Holotype male [a single specimen in original description, assumed as holotype] in BMNH [not presently in BMNH (when we requested it for analysis), not examined].

Length: 2.2 mm (original description and Szymczakowski, 1975).

Type locality: “ Colombie ”.

Distribution. Colombia: known only from “ type locality” (original description; Szymczakowski, 1975).

Taxonomic Remarks.

1) See Taxonomic Remarks under Adelopsis ascutellaris , above.

2) Szymczakowski (1975: 14) stated that it is very probable that A. ovalis is a synonym of A. brunnea ; and he proposed to use the latter as the valid name [but the former has page precedence] if this synonymy is proved right. However, this ‘potential synonymy’ has never been used in the literature afterwards. We here presently consider both as valid species, and do not propose a revalidation because we understand that Szymczakowski´s statement is not a valid taxonomic act.

3) As proposed in Gnaspini (1996: 539) and Peck et al. (1998: 62), all subspecies of A. brunnea Jeannel 1936 are here raised to species status. The combination of the variation observed on aedeagus, genital segment, eyes, antenna, male mesotibia, and spermatheca allow taxon recognition (see discussion under each of these taxa). As a result, this would be the only subspecies left in the species. Therefore, we here abandon the use of subspecies in A. brunnea .

4) This species is tentatively assigned to subgroup, since the genital segment (which is here considered important for subgroup assignment) is unknown.
