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 : 31

Adelopsis mrazi , new species

( Figs. 137–142 )

Adelopsis grouvellei ; Szymczakowski, 1963: 671 [and Figs. 10–12 or 13—it is not possible to recognize which one refers to the specimen here assigned to this species] (misidentification—Gnaspini, 1996: 540, and see Notes under A. grouvellei , below).

Holotype, male (NMPC). Type locality and data: Brazil: São Paulo State: São Paulo, Jaro Mráz leg. Labels : “ São Paulo / Bras. Mráz lgt / Mus. Pragense ”. Specimen here illustrated. Note : specimen misidentified as Adelopsis grouvellei Jeannel, 1936 in Szymczakowski (1963: 671) — Gnaspini , 1996: 540, and see Notes under A. grouvellei, below.

Length: 2.0 mm.

Short Description. Data on eyes and wings not observed. Apex of the right lobe of the aedeagus subrectangular, with the apical margin straight ( Fig. 140 ), with a rounded margin, in lateral view ( Figs. 137, 139 ). Flagellum shorter (about 3/ 4 in length) than aedeagus, strongly curved, almost forming a 1-turn coil. Proportion aedeagus/elytron = 0.39, considerably large in comparison with other species in the genus. Spiculum gastrale of the genital segment with a very short and wide base, with a curved margin, and divided at apex, with long branches ( Fig. 142 ). Female unknown.

Etymology. The name is given to honor Jaro Mráz, collector of the present species, and of many cholevines elsewhere.

Distribution. Brazil: São Paulo State: known only from type locality.

Taxonomic Remarks. The lateral view of the aedeagus ( Fig. 137 ), together with the frontal view of the tip of the right lobe of the aedeagus ( Fig. 140 ), seems to help in the recognition of this species.
