Description:

Habitus as in Fig. 17. Highly similar to P. picea ;

distinguished only by the darker coloration and

the morphology of the aedeagus. Coloration

of body blackish; legs usually dark brown;

antennae uniformly dark brown to blackish, basal

antennomeres at most only slightly paler than

remainder of antennae. External characters as in

P. picea ; distinguished only by the morphology of

the aedeagus.

♂: median lobe of aedeagus 0.40-0.42 mm long

similar to that of P. picea , but basal projection

of ventral process acute or rounded apically, not

truncate ( Figs 18-24 ).

♀: spermatheca similar to that of P. piceapicea ( Fig. 25 )

Etymology: The name (adjective) is derived from

Corsica, where the species is apparently endemic.

Comparative notes:

From other Pronomaea species , except P. picea ,

P. corsicanacorsicana is readily distinguished by the

pronounced projection at the base of the ventral

process of the aedeagus (lateral view). In contrast

to P. picea , this projection is apically acute or

rounded, not truncate. A comparison of males

of P. picea and P. corsicanacorsicana from various localities

suggests that this difference is constant (compare Fig. 17: Pronomaea corsicana sp. n.: habitus Figs 9-13 and 18-23 ). (photo by Marc Tronquet). Scale bar: 1.0 mm.

Distribution and bionomics:

Pronomaea corsicanacorsicana is apparently endemic to Corsica ( Map 2 ). Previous records of P. rostrata from this island probably refer to this species, at least in part. The type specimens were collected at altitudes of up to 2020 m, some of them were sifted from the litter of subalpine shrubs or found in moss near streams, during the period from April through August. Two specimens were caught on the wing (car-net) in May.
