Assing, Volker, 2007, A revision of the species of Pronomaea E of the Western Palaearctic region, including Middle Asia (Coleoptera: Staphylinidae: Aleocharinae: Pronomaeini), Beiträge Zur Entomologie = Contributions to Entomology 57 (2), pp. 367-396 : 383

Pronomaea sardoa sp. n. ( Figs 32-34 , Map 1 )

Type material:

Holotype ♂: "I-Sardinia, 5, XI.85, H. Winkler / Holotypus ♂ Pronomaea sardoa sp. n. det. V. Assing 2007 " (cAss) . Paratypes: 1 ♂: " Sinnai ( CA), Riu longu, 15.VI.1974, Meloni" (cZan) ; 1 ♀: "9.9.92, Sardinien, Lago Coghinas, leg. Wunderle " (cWun) ; 1 ex.: " Sorgono , Sardinien, 1911 [name of collector illegible]" ( SMNS) .

Description:

External characters as in P. picea ; distinguished only by the morphology of the aedeagus.

♂: median lobe of aedeagus small, approximately 0.38 mm long; general morphology similar to that of P. picea , but ventral process more slender in ventral view, in lateral view more strongly bent, apex of ventral process more slender, and projection at base of of ventral process much less prominent ( Figs 32-34 ).

♀: spermatheca similar to those of P. piceapicea and P. corsicana .

Etymology: The name (Latin, adjective) is derived from the name of the island where the species is endemic.

Comparative notes:

The aedeagus of P. sardoa is most similar to that of P. sicula , but distinguished by smaller size, a less slender apex of the ventral process, the more pronounced angular projection at the base of the ventral process, and by the shorter flagellum in the internal sac.

Distribution and bionomics:

The species is the only representative of the genus in Sardinia, where it appears to be endemic ( Map 1 ). The types were collected in June, September, and November, one of them apparently on a lake shore. Additional bionomic data are not available .
