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 : 54-55

Paulipalpina coatepec , new species

( Figs. 250–255 )

Adelopsis simoni ; Szymczakowski, 1968: 14 [and Fig. 4 ] (misidentification—Gnaspini, 1996: 540, and see Notes under P. simoni , above).

Holotype, male ( ZMHB). Type locality and data: Mexico: Veracruz State: Coatepec 6, Flohr coll. Note: specimen misidentified as Paulipalpina simoni ( Portevin, 1923) in Szymczakowski (1968: 14) —Gnaspini, 1996: 540, and see Notes under P. simoni , above). Specimen here illustrated.

Length: 1.95 mm (our measurement).

Short Description. Eyes normal. Winged. Right lobe of the aedeagus slightly longer and thicker than left lobe ( Figs. 250, 251 ). Right lobe pointy, with apex enlarged, slightly curved and shortly projected ventrad, in lateral view ( Fig. 250 ). Dorsal opening of the aedeaus round and taking about 1/7 of aedeagus length ( Fig. 251 ). Flagellum shorter (about 3/ 4 in length) than aedeagus ( Fig. 251 ). Proportion aedeagus/elytron = 0.39. Spiculum gastrale of the genital segment short and straight ( Fig. 253 ). Male mesotibia medially bent internally ( Fig. 255 ). Female unknown.

Etymology. The name is given as a noun in apposition, referring to the type locality.

Distribution. Mexico: Veracruz State: known only from type locality.

Taxonomic Remarks. In lateral view, the tip of the aedeagus of P. coatepec sp. n. resembles that of P. consuelo sp. n., from Peru, and, slightly, that of P. claudicans (Szymczakowski, 1980) , from Brazil. However, in frontal view, it markedly differs from that of the remaining species described so far in the genus, except for its slight resemblance to that of P. arcuata Salgado, 2014 , from Peru, from which it differs in lateral view.
