Pholcus sidorenkoi – Huber 2011b: 340 , figs 1538, 1642–1644 . Diagnosis This species resembles P. cophenius Senglet, 2008 (see Senglet 2008: 365 , figs 57–65) in having similar male chelicerae ( Fig. 6D ), appendix ( Fig. 6C ), and female external genitalia ( Fig. 6A ), but can be distinguished by slightly thicker male pedipalpal trochanter ( Fig. 5 A–B), by absence of distal sclerites on less curved procursus ( Fig. 5 C–D), by more elongate uncus ( Fig. 6C ) ( Huber 2011b ), and by more elongate vulval pore plates ( Fig. 6B ).

As in Fig. 6D , with pair of proximo-lateral apophyses, pair of distal apophyses provided with two teeth each, and pair of frontal apophyses. PEDIPALPS. As in Fig. 5 A–B; trochanter with long curved ventral apophysis; femur with small dorsal apophysis proximally and small ventral modification; procursus simple proximally but complex distally, with two prolatero-dorsal spines; uncus with scaly edge; appendix with scales distally and flat prolateral process; embolus short and weakly sclerotized, with some transparent projections distally. Retrolateral trichobothrium of tibia I at 6%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with approximately 5 distinct pseudosegments.
