Dioscoridillo melanoleucos Ferrara & Taiti, 1996

Dioscoridillo melanoleucos Ferrara & Taiti, 1996: 132, fig. 8; Taiti & Ferrara, 2004: 302, fig. 60, pl. 26.

Material examined. Socotra: many ♁♁ and ♀♀, Lem-chegeranit, 12°35'04.5"N 53°30'49.3"E, under stones in meadow near pool, 12.I.2003, leg. S. Taiti, MZUF- 9274 ; 5 ♁♁, 5 ♀♀, same data, NHCY (MZUF); 5 ♁♁, 3 ♀♀, Ma’lih, Fisreher, 12°37'38"N 53°30'42"E, along wadi, 690 m, 12.I.2003, leg. S. Taiti and A. K. Nasher, MZUF-9275 ; 2 ♁♁, 2 ♀♀, same data, NHCY (MZUF) .

Remarks. These specimens and those from SW of Qeysoh cited in Taiti and Ferrara (2004) have an uniformly pale instead of grey colour (see pl. 26 in Taiti and Ferrara 2004) as in the populations from Nojid, Wadi Ayhaft, Diksam, Hagghier Mts and Momi, while all morphological characters are identical. As in the case of Socotroniscus sacciformis, a molecular analysis is necessary to confirm that the pale and grey forms belong to the same species.

Distribution. The species is endemic to Socotra Island.
