Cymbionotum (Procoscinia) negrei Perrault 1994

( Fig. 15F , 16 )

Cymbionotum negrei Perrault 1994: 208 . TYPE MATERIAL: three specimens, card­mounted (MNHP). HOLOTYPE male, labeled: "MUSEUM PARIS/ VENEZUELA / BAS SARARE / F. GEAY 33­96"; "Sous les écorce/ darbres" [handwritten]; " HOLOTYPE " [red paper] . PARATYPES, male and female. Male, labeled: " MUSEUM PARIS / VENEZUELA / HAUT APURE / F. GEAY 33­96"; " PARATYPE " [red paper]; Cymbionotum / negrei m. [handwritten]/ PARATYPE / G. G. Perrault det. [printed] 1992" [handwritten]. Female, "Venezuela, S. Fern. do Apure, L. Laglaize 1896"; " MUSEUM PARIS / ex. Coll./ R. Oberthur " [pale green paper]; " PARATYPE " [red paper]; " PARATYPE / Cymbionotum /negrei m. [handwritten]/ G. G. Perrault det. [printed] 1992" [handwritten] .

Type area. Venezuela: Bas Sarare .

Recognition. Adults of this species are markedly similar to those of C. fernandezi , differing in absence of microlines from most of the dorsal surface, and by average smaller size, narrower vertex, narrower head in relation to pronotum, and narrower pronotal base (lower values for PWB/PWA, Table 12). The phalli of these two species are similar in form, but that of C. negrei ( Fig. 15F ) is narrower, with the preapical portion of the shaft bent more distinctly ventrad, and ventral surface generally pale (cf. Fig. 15B ).

Description. With recognition features as specified above, and in the subgeneric treatment; similar generally to C. fernandezi . Male genitalia with phallus as in Fig. 15F .

Habitat. The holotype was collected from under bark of a (presumably fallen) tree. From the locality data, we infer that C. negrei is mesophilous, living in the rain forest vegetation zone (Table 17), at an altitude of less than 200 m. We do not believe that the species is subcortical, but that is a possibility.

Geographical distribution ( Fig. 16 ). This species is known only from two localities in the Apure River Basin of Venezuela.

Relationships and chorological affinities. Based on shared morphological features, geographical proximity, and allopatric ranges, C. negrei is inferred to be the adelphotaxon of C. fernandezi , new species.

Material examined. We have seen the type series, only. For details, see the synonymical section, above.
