Gnaspini, Pedro & Peck, Stewart B., 2019, Redescription of the ‘ older Adelopsis’ species (Coleoptera: Leiodidae: Cholevinae: Ptomaphagini) based on the analysis of type specimens, Zootaxa 4696 (1), pp. 1-62 : 6

Genus Adelopsis Portevin

Adelopsis Portevin, 1907: 71 ; Jeannel, 1936: 59 (redescription) (sensu Gnaspini, 1996: 533 and Gnaspini and Peck, 1996: 407, redescription). Type species: Catops ruficollis Portevin, 1903 , here considered a senior synonym of Adelopsis heterocera Portevin, 1907 , originally established as type species, by monotypy.

Iutururuca Gnaspini, 1993: 79 (as subgenus). Type species: Adelopsis leo Gnaspini (orig. des.). n. syn.

Excelsiorella Salgado, 2008a: 210 (as genus); Gnaspini et al., 2016: 274 (synonymy). Type species:

Excelsiorella latissima Salgado (orig. des.).

Note: Gnaspini (1993: 79) described the subgenus Iutururuca (as subgenus of Adelopsis ) for a group of Brazilian species having the spiculum gastrale of the genital segment divided at the apex. Gnaspini (1996) discussed that this feature also appears in other groups of species (e.g., in the group elephas), and that author decided not to assign species to subgenus until a proper phylogenetic analysis of Adelopsis is conducted, which is needed to assure that the remaining, non- Iutururuca , species of Adelopsis do form one (or more) monophyletic group(s) [namely, subgenus/subgenera]. Considering that this feature appears within different groups of species (for instance, in the group ascutellaris, in taxa that were formerly considered to belong in subspecies of the same species; see also our discussion about groups of species), we prefer to propose here the synonym.

Therefore, Adelopsis is now considered to have no subgenera.

Besides the typical characters of the tribe, species of Adelopsis are characterized by having (except when noted): Antenna reaching base of elytra when laid back. Abdominal ventrites (sternites), especially sternites V–VII (preceeding the genital segment VIII), may be altered. Aedeagus broad; base curved downwards, with the orifice somewhat facing ventrally, at an angle of 45° from the horizontal axis (but in a few species it follows the longitudinal axis of the aedeagus—see our discussion about species groups); apical orifice dorsally subterminal and cuting the left side of aedeagus; flagellum elongate, strongly developed. Parameres flat, curved, shorter than aedeagus, bearing 3 small terminal setae, inserted close to each other. Genital segment globular, slightly longer than broad; lateral lobes bearing several long and short setae; the spiculum gastrale may be straight and of the same width along its axis, or its anterior apex may be enlarged or divided. Spermatheca varies among species; it is frequently 2-turns coiled (and may have more turns) and always ends with a distinct bulb.
