Episinus Walckenaer, in Latreille, 1809

(Fig. 8D-F)

Walckenaer, in Latreille, 1809. Genera Crustaceorum et Insectorum, vol. 4, p. 371. Type species by monotypy: E. truncates Latreille, 1809, ibid.

Diagnosis. The opisthosoma is straight in relation to the location of the pedicel while in all other spintharine genera it is inclined. Also, the posterior portion of the opisthosoma is widest in dorsal view (Fig. 8D-E), while in the remaining genera the widest portion is anterior or in the middle. An “H” -like architecture of the web is shared with Thwaitesia and Spintharus . Levi (1954a, 1964a) included the characters horns between the anterior eyes, eyes often on tubercles, and eyes with reddish pigment, as diagnostic characters, all of which we could not observe in the specimens examined.

Distribution . Worldwide, mainly in warmer areas; relatively species rich in North, Central, and South America, poorly known from the Caribbean (Platnick 2013).
