Types: Scytodes rufipes Lucas, 1834 ♀ Holotype from Guatamala: No specific locality [not seen]. Scytodes omosites Walckenaer, 1837 ♀ Holotype from Guiana: No specific locality, Leschnault and Doumere [not seen].

Note: No specimens of this species were looked at, but it is included here for completeness, as it occurs in the Afrotropical region in published records.

Diagnosis: Male palp tibia long, cymbium short, similar to L. fontainei , L. foutadjalloni , L. rufescens and L. vonwredei ; differing from L. fontainei in the femur/cymbium ratio being more than 4.5; differing from L. foutadjalloni in the pulp bulb being about a third of tibia length; differing from L. rufescens and L. vonwredei in the palp tibia length/height ratio being less than 2.0 ( Fig. 9H). Female spermathecae consist of two long, finger-like sacs; median sac narrow, lateral sac wide; copulatory tubes wide, slightly narrowing to spermathecae, joined medially; differing from all other species in this respect, closest species being L. lacroixi from which it differs in the number and structure of the spermathecae ( Fig. 10H).

Female: (from Gertsch & Ennik 1983): TL = 6.5; CL = 2.6; CW = 2.3; CLL = 0.4. AME-LE 0.24; Eye diameter 0.16.
