(Fig. 9 B, C)

O. P.-Cambridge, 1894. Biologia Centrali-Americana, Araneidea, vol. 1, p. 125. Type species by monotypy: S. bicolor O. P.- Cambridge, 1894, ibid., pl. 17, fig. 5.

Diagnosis. Species of Stemmops present the posterior median eyes closer to the lateral eyes (Levi 1955) than between themselves (Fig. 6 C, D). In all other spintharines their posterior median eyes are far from the lateral eyes. A sclerotized ring around the spinnerets is exclusive of this genus (Aganarsson 2004, figs. 63 B, 74 A).

Distribution . Mostly occur in warm parts of America, from U. S. A. to Brazil. Two species are found in China, Japan and Korea (Levi 1964b; Yaginuma 1969; Platnick 2013).
