The male of Megacormusgranosus (Gervais, 1844) with comments on its hemispermatophore (Scorpiones, Euscorpiidae).

ABSTRACT

The male of Megacormusgranosus is described for the first time and the female redescribed. A homology scheme proposed recently is applied to hemispermatophore structures. The specimens were collected in an oak forest from Pico de Orizaba Volcano at an average altitude of 2340 m. All adult males were collected by pitfall traps, whereas all adult females and both sex immatures were collected using Berlese funnels, suggesting that males are comparatively more mobile within the leaf litter layer, probably due to mating season.
