Pholcus buatong  species group

This species group is newly proposed to include one species previously part of the Ph. halabala  group ( Ph. satun Huber, 2011  ), one species previously tentatively assigned to the Pholcus ethagala  group ( Ph. schwendingeri Huber, 2011  ), and a newly described species ( Ph. buatong Huber  , sp. nov.). They share three putative synapomorphies, (1) the complete reduction of distal anterior apophyses on the male chelicerae ( Fig. 156View Figs 154 – 158); (2) the very distinctive dorsal bulging of the male palpal patella ( Fig. 155View Figs 154 – 158; angle between femur and patella ~120–125° rather than ~180° as in typical pholcids); and (3) the large, heavily sclerotized ‘knob’ on the epigynum ( Figs 184, 187, 190View Figs 184 – 192). The group is strongly supported by preliminary molecular data (A. Valdez-Mondragón, B.A. Huber & D. Dimitrov unpublished data). Pholcus schwendingeri  and Ph. buatong  sp. nov. also share a distinctive whitish membranous process retrolatero-distally on the procursus (arrows in Figs 155View Figs 154 – 158, 180View Figs 173 – 183). Otherwise this group appears rather inhomogeneous: Pholcus schwendingeri  males have extremely long eye stalks ( Fig. 173View Figs 173 – 183) while males of the other two species have short eye stalks ( Fig. 155View Figs 154 – 158); Pholcus buatong  sp. nov. is rock-dwelling while the other two species are leaf litter dwelling; Pholcus satun  has small AME, while the other two species lack AME; Pholcus satun  males have only one bulbal process (sclerotized embolus), while males of the other two species have a membranous embolus plus an appendix. In all three species, egg-sacs are carried in front of the body ( Figs 145, 152View Figs 143 – 152) as in typical pholcids. This species group is known from southern Thailand and northern mainland Malaysia ( Fig. 153View Fig. 153).
