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 140View Figs 140 – 144, 150View Figs 148 – 156, 157View Figs 157 – 160), by shape of procursus (presence of dorsal process; absence of distal spine-like process; Figs 141View Figs 140 – 144, 158View Figs 157 – 160), 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. 139View Figs 131 – 139); eight eyes; male chelicerae almost unmodified (indistinct lateral humps proximally; Fig. 142View Figs 140 – 144); male genital bulb without uncus; epigynum weakly sclerotized, with numerous transversal folds ( Figs 143View Figs 140 – 144, 156View Figs 148 – 156, 159View Figs 157 – 160).
