Spermophora maculata Thorell 1898: 276 (preoccupied).

Spermophora thorelli Roewer 1942: 346 (replacement name).

Type material examined. Holotype: Female (MSNG), Bhamo, Myanmar, 1885–1889, L. Fea leg.

Diagnosis. The species can be distinguished from all known congeners by details of female genitalia ( Figs 5 A–B; presence of distinct, anterior marks on epigynum in ventral view, different position of epigynal pockets, different shape of sclerotized arch, and long pore plates).

Redescription. Female (holotype): Total length 1.65 (1.77 with clypeus), prosoma 0.63 long, 0.70 wide, opisthosoma 1.02 long, 0.79 wide. Leg I: – (2.55 + 0.31 + 2.53 + – + –), leg II: – (1.84 + 0.27 + 1.55 + – + –), leg III: 4.95 (1.41 + 0.23 + 1.13 + 1.59 + 0.59), leg IV: – (2.01 + 0.24 + 1.63 + – + –); tibia I L/d: 35. Dorsal shield of prosoma, ocular area, clypeus and legs yellowish, but marks beyond recognition; sternum light brownish. Opisthosoma pale grey, with spots dorsally and laterally. Distance PME-PME 0.06; diameter PME 0.10; distance PME-ALE 6 μm. Ocular area slightly elevated. No thoracic furrow, only median dark line. Sternum wider than long (0.47/0.45). Epigynum ( Fig. 5 A) simple and weakly protruding, with distinct marks anteriorly and pair of pockets posteriorly. Vulva ( Fig. 5 B) with a rainbow-shaped, sclerotized arch anteriorly and two long pore plates. Leg hairs lost.
