Miopsalis globosa ( Schwendinger & Giribet, 2004) View in CoL new comb.

Stylocellus globosus Schwendinger & Giribet, 2004: 1423 , figs. 1–29.

Comments: This highly troglomorphic species has moved between Fangensinae subfam. nov. and Miopsalis in various morphometric phylogenetic analyses ( Clouse et al. 2009). Although it has placed most commonly with the former, the case for its placement in Miopsalis appears stronger in light of the subfamily features identified here. The extremely rounded opisthosoma, with its lateral flange and shortened posterior, surely complicate morphometric studies and may push analyses to combine M. globosa new comb. with convergently troglomorphic species (which includes all of Fangensis ). It does not, however, present the most distinct feature of Fangensinae subfam. nov., which is the enormous size of the fourth coxae. Three other discrepancies could be attributable to the opisthosoma of M. globosa new comb. being enlarged and widened, but they further weaken the case for placement in Fangensinae subfam. nov.: the ozophores are not perpendicular to the long body axis, the posterior prosoma is not enlarged, and the fourth coxae do not have lateral edges parallel to the long body axis. Once we no longer consider Fangensinae subfam. nov. (nor, obviously, Meghalaya) as options for a generic placement, we have to consider two characters that might ally M. globosa with Stylocellus or Leptopsalis : the strongly concave posterior gonostome and the rounded profile. But these are relatively variable characters across the family and contradicted by a combination of Miopsalis -like charactacter states: tapered ozophores, straight sternal opisthosomal sulci, large anal gland pore, large and flat ventral prosomal complex, and significant cheliceral sculpturing.
