Diagnostic notes.

Glomeremus mediopictus differs markedly from G. capitatus and G. pileatus . It is much smaller, has tiny scale-like wings, has a much more delicate appearance and has different black markings on the body and legs (Uvarov in Uvarov and Popov (1957)) (Fig. 196 View Figure 196 ). The most important difference with the other two species is the terminalia of males and females. In males of G. capitatus and G. pileatus , the hooks on the posterior margin of the 10 th tergite are directed backwards and slightly upwards. Conversely, in G. mediopictus , these hooks point downwards and inwards (Fig. 188 View Figure 188 ). In female G. mediopictus , the subgenital plate has a transverse crescentic swelling in the middle, whereas G. capitatus and G. pileatus have an anteflexed, bifid structure (Fig. 189 View Figure 189 ).

Distribution and occurrence.

The species is endemic to Socotra. Only a few records are known, scattered over the island (Fig. 197 View Figure 197 ), but the species is probably overlooked. Uvarov (in Uvarov and Popov (1957)) mentioned that the collection site of the holotype is at 3000 ft [914 m a. s. l.]; Popov (1984) noted 100 m a. s. l. (300 ft) as elevation, as also stated on the label. We consider the latter to be correct (see Discussion).

Habitat and biology.

All records are from high scrubland with succulents. The species occurs at low elevations from 10–350 m a. s. l. In 2009, it was found at night in various shrubs, like Senna socotrana , Jatropha unicostata and Cissus subaphylla (Fig. 198 View Figure 198 ). Massa (2009) collected the species in Croton socotranus . It is possibly associated with more humid localities than G. pileatus . Records are from February to April.
