Pholcus domingo Huber

Description

Pholcus domingo species group

Diagnosis

The two species included in this group are medium-sized, long-legged spiders (body length ~4.5, male leg 1 length:~35–40), distinguished from similar P. kerinci group by bipartite appendix (sclerotized retrolateral and whitish prolateral part; Figs 140, 150, 157), by shape of procursus (presence of dorsal process; absence of distal spine-like process; Figs 141, 158), and by dorsal trichobothrium of male palpal tibia in ‘usual’ position (i.e., at ~45% of tibia length, versus 55–60% in P. kerinci group); from other species groups in Pholcus by combination of the following characters: elongate abdomen angular dorso-posteriorly (Fig. 139); eight eyes; male chelicerae almost unmodified (indistinct lateral humps proximally; Fig. 142); male genital bulb without uncus; epigynum weakly sclerotized, with numerous transversal folds (Figs 143, 156, 159).
