Ummidia salebrosa (Simon, 1892) Fig. 72 , Map 6

Pachylomerus salebrosus Simon, 1892: 530; HOLOTYPE: 1 ♀ (1894/300) from St Vincent, 13.2536 -61.187 6, 863 m a.s.l., coll. HH Smith, deposited in NHMUK, examined.

Diagnosis.

Ummidia salebrosa females can be differentiated from all geographically proximate species except U. asperula by having narrow stalked spermathecae which curve slightly medially and then coil with bulbs facing dorsally. Females can be differentiated from U. quijichacaca , U. asperula , U. tunapuna , and U. nidulans by having very large palpal endite and labial cuspules.
