Megaphyllum glossulifer: Enghoff & Kime 2009; Lazányi et al. 2012: 13, 41.

Distribution. Bulgaria (Vagalinski & Stoev 2007, Lazányi et al. 2012).

Diagnosis. Differs from other members of the species group by the wider, stouter posterior opisthomere process (pp) (Figs 10a–b, 10d) compared to its generally slender, elongated condition in the remaining species.

Opisthomere’s (Figs 10a–b, 10d) posterior process (pp) broad, gradually narrowing, with a pointed tip, subequal to solenomere’s posterior process (psp). Anterior solenomere process (asp) very short.

Body length and height: males: 19–24mm, 1.4–1.85mm; females: 25–27mm, 2.2–2.4mm.

Remarks. This seems to be the smallest species of the subgenus, challenged only by M. sjaelandicum, for which similar though somewhat smaller values were measured. It is endemic to Bulgaria known only from the highest regions of Rila, Stara Planina and the Rhodope Mountains (Lazányi et al. 2012). Individuals collected from these three mountains showed no significant differences in their external morphometry and gonopodal details. The species is most similar to M. dentatum, considering the shape of the opisthomere. In M. glossulifer, however, the posterior opisthomere process is stouter, and the posterior solenomere process is shorter; the promere in contrast to M. dentatum is plain—rounded—, distally gradually narrowing, and without apical protrusions (see Fig. 10c in comparison with Fig. 9c).
