Silva, Estevam Luís Cruz Da & Lise, Arno Antonio, 2006, Description of two new spider genera of Trechaleidae (Araneae: Lycosoidea) from Northern Brazil, Zootaxa 1275, pp. 61-68 : 62-64

Amapalea gen. n.

Figs 1–5 , 13–17

Type species. Amapalea brasiliana sp. n.

Etymology. The generic name is a noun and refers to the type locality. The grammatical gender is feminine.

Diagnosis. This genus resembles the Trechaleidae genera Dossenus , Enna and Paradossenus by the presence of short and straight tarsi. The bulbus of male palpus is small, compared to the length of cymbium; the tegulum presents a prominent projection ( Figs 3 , 14 ) not found in any other Trechaleidae genera, like Paratrechalea Carico, 2005 and Paradossenus F. O.P.­Cambridge, 1903 without tegular projection. The guide of median apophysis are small, compared to the length of tegulum and subtegulum, and conspicuous in ventral view ( Figs 3–4 , 14 ); the ventral division of median apophysis is dilated at the basal portion ( Figs 3 , 14 ).

Description. Carapace moderately elevated. Chelicerae, almost glabrous. Legs yellowish, brownish dorsally. Anterior and posterior eye rows moderately procurved, ALE the smallest, PLE the largest. Chelicerae with 3 teeth on the promargin of the fang furrow and 3 on the retromargin, being the median the largest. Pairs of ventral macrosetae in tibia: I 4, II 4, III 3, IV 3.

VP—ventrodistal protuberance of male palpal tibia.

Palpus tibia ( Figs 2–5 ) with strong spines ( Figs 2–5 , 15 ). The retrolateral tibial apophysis with one branch ( Figs 3–5 , 15 ).

Distribution. Brazil (Amapá).
