Genus Uthina Simon, 1893 View in CoL View at ENA

Uthina Simon 1893: 476 View in CoL . Type species Uthina luzonica Simon, 1893 View in CoL , by original designation.

Diagnosis. This genus can be distinguished from all known pholcid genera by the combination of a cylindrical opisthosoma, the presence of six eyes, two pairs of apophyses (proximo-lateral and disto-frontal) on the male chelicerae ( Figs 48 View FIGURES 48 – 52 , 55 View FIGURES 53 – 56 ), a ‘knee’ and the absence of dorsal spines on the procursus ( Figs 44–45 View FIGURES 44 – 47 , 53–54 View FIGURES 53 – 56 ), a curved uncus ( Figs 44 View FIGURES 44 – 47 , 53 View FIGURES 53 – 56 ) and a usually slender bulbal appendix ( Figs 45 View FIGURES 44 – 47 , 54 View FIGURES 53 – 56 ), as well as by the presence of a ‘knob’ on the barely sclerotized epigyne ( Huber 2011a).
