Megaphyllum projectum Verhoff, 1894

Figs 4a–l

Diagnosis. M. projectum differs from all consubgeners by the longitudinal anterior process of the opisthomere (ap) (i.e. directed parallel to main opisthomere body, best seen from lateral view, see Fig. 4f) together with the cockscomb-like posterior solenomere process (psp), best seen from mesal view (Fig. 4k).

The species shows sexual dimorphism in body colour: males are uniformly dark grey, while females are brownish-yellow with two bright dorsal bands divided by a wide dark band.

Remarks. Type species of the genus Megaphyllum and one of the most frequent Megaphyllum species in Central European deciduous forests. Originally, Verhoeff described five nominal subspecies: M. p. alticolum (Verhoeff, 1897), M. p. deubeli (Verhoeff, 1899), M. p. dioritanum (Verhoeff, 1907), M. p. kochi (Verhoeff, 1907) and the nominotypical subspecies M. p. projectum Verhoeff, 1894 . Their validity was discussed by Lazányi & Korsós (2011) where only three of them proved to be valid. This is the only species within the subgenus Megaphyllum sensu stricto for which valid subspecies are recognized. They are further discussed in separate sections.
