Stigmatica incerta (Kuester, 1861)

Figs 60.5, 60.6, 61.7

Distribution.

Stigmatica incerta is found in the Madonie and Nebrodi mountains in Sicily and in southern Calabria.

Specimens examined.

Italy, Calabria, Vibo Valentia, Serra San Bruno. 945 m asl, 38°32'42.36"N, 16°19'09.42"E, W. De Mattia and J. Macor leg. and det., 3 dissected spm .

External morphology of the genital organs

(Fig. 60.5). The FO is 2.5 × as long as the V. The FDBC is remarkably longer than the SDBC+BC. The BC+SDBC is short, bulky, club-like in shape, with a more or less clear distinction between the SDBC and the BC. The D is much longer than the SDBC+BC and thinner. The PC is ~ 4 × longer than the V. The P is moderately wide in diameter and swollen. The transition between P and EP is clearly visible. The PR is long and robust. The E is longer than the P but thinner in diameter.

Internal morphology of the genital organs

(Fig. 60.6). The V presents few smooth longitudinal pleats, distally merging one into another, that stop immediately before entering the A. The P shows three or four slightly fringed pleats that continue almost as far as the A. These penial pleats tend to distally merge one into the other. The pseudopapilla is moderately long and smooth. It originates directly from the E wall, which is connected with the ELP by thin smooth longitudinal pleats. The two ELP are moderately fringed. The epiphallar formula is: PP(ER)+ELP.

Remarks.

This species is restricted to higher altitudes from 800 m asl up. It is found in mixed Fagus and Picea forests on barks and moss in humid habitats. Benoit (1876: 152) reports this taxon also on barks of Acer campestre (maple) from the Madonie and Quercus sp. (oak) from Gibilmanna (Palermo).
