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 : 55-56

Paulipalpina jeanneli , new species

( Figs. 256–261 )

Adelopsis simoni ; Jeannel, 1936: 66 [and Fig. 97 ; and maybe also Fig. 79 —see Note] (misidentification—Gnaspini, 1996: 540, and see Notes under P. simoni , above).

Holotype, male ( BMNH). Type locality and data: Brazil: São Paulo State: Santo André, Parque Estadual de Paranapiacaba [given on type label as “ Alto da Serra ”], G.E. Bryant. 12.iii.1912, G. Bryant Coll. 1919-147. Note: specimen misidentified as Paulipalpina simoni ( Portevin, 1923) in Jeannel (1936: 66) —his Figs. 79 and 97 referred to the illustrated male as “from Venezuela ”, but he had at hand 1 female from Venezuela and 1 male from Brazil; therefore at least his Fig. 97 (and maybe also Fig. 79 ) refers to this male from Brazil, and not from Venezuela, as already mentioned in Szymczakowski (1968: 14) —see also Gnaspini, 1996: 540, and Notes under P. simoni , above. Note: the specimen was previously dissected, and the aedeagus was missing (but considered to be the one illustrated in Fig. 97 in Jeannel, 1936) [see Note under MNHN, in ‘Methods and Materials’ – this specimen aedeagus might refer to a glass slide at MNHN collection, labeled ‘ Adelopsis simoni Alto della Sierra, Brésil (édéage)’]. Specimen here illustrated.

Length: 1.8 mm (our measurement—very different from the values from Jeannel, 1936 —either 2.2 or 2.5 mm—see Note under P. simoni ).

Short Description. Eyes normal ( Fig. 257 ). (Seemingly) Wingless.Aedeagus missing. Spiculum gastrale of the genital segment short and straight ( Fig. 256 ). Male mesotibia slightly curved internally ( Fig. 260 ). Female unknown.

Etymology. The name is given in honor of René Jeannel, who examined the specimen, and for his large contribution to systematics of cholevines and many other beetles.

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

Taxonomic Remarks. Considering the illustration in Jeannel (1936: Fig. 97 ), the tip of the aedeagus of P. jeanneli sp. n. seems different from that of the remaining species described so far in the genus, although having a slight resemblance to that of P. claudicans (Szymczakowski, 1980) , also from Brazil, and P. clavigera Gnaspini and Peck, 1996 , originally described from Costa Rica and Panama. However, male specimens of the latter two species have mesotibia bent medially, whereas the specimen of P. jeanneli sp. n. does not.
