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 : 32

Adelopsis szymczakowskii , new species

( Figs. 143–149 )

Adelopsis benardi ; Szymczakowski, 1963: 670 (as “? bernardi ” [sic]) [and Figs. 8–9 ] (misidentification—Gnaspini, 1996: 540, and see Notes under A. benardi , above).

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 benardi ( Portevin, 1923) in Szymczakowski (1963: 670) — Gnaspini , 1996: 540, and see Notes under A. benardi, above.

Length: 2.5 mm (our measurement; agrees with Szymczakowski, 1963).

Short Description. Data on eyes and wings not observed.Apex of the right lobe of the aedeagus subquadrate and bearing two triangular projections at the sides ( Fig. 145 ), with a sinuate margin ending almost blunt with a pointy projection, in lateral view ( Fig. 143 ). Flagellum almost as long as aedeagus, strongly curved and projected laterally, forming a tape-shaped coil longer than 1-turn ( Fig. 143 ). Proportion aedeagus/elytron = 0.33. 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. 147 ). Female unknown.

Etymology. The name is given in honor of Wacław Szymczakowski, who examined the specimen, for his large contribution to systematics of cholevines.

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

Taxonomic Remarks. The lateral view of the aedeagus ( Fig. 143 ), together with the frontal view of the tip of the right lobe of the aedeagus ( Fig. 145 ) and the coiled tape shaped flagellum ( Fig. 143 ), seems to help in the recognition of this species.
