Lewindromia unidentata (Rüppell, 1830)

Female without dorsal surface of the carapace, Perim, Jousseaume coll. (MNHN-B 6940).

Sternites 7 and 8 are tilted, being almost perpendicular in relation to the precedent ones. The sternal sutures 7/8 are wide apart posteriorly, get abruptly close to each other at the level of the P3, where they are marked by a thick ridge; the rounded apertures of the spermathecae end together on a slight prominence between the P2 coxae. The bulb of the spermatheca is tapering and prolongs in the form of a basal thickening; its dorsal surface has a raised part forming a flat, well defined and circular area; no anterior visible prominence. The chamber has its two sheets lacking a marked space between them; its walls are weakly ornamented. The narrow tube shows an abrupt change of direction and is only sligthly widened distally.
