Description
(Figs5─8, 17;Appendix II,Figs B 1─ B 4)
Diagnosis
Diagnosis:The male resembles those of A.diversipes and A.gamba sp.nov.by lacking a tibial apophysis on leg I.It differs from that of A.diversipes by the embolus being two to three times longer than the tegulum,with a curvature of less than180°(Figs5─7);from those of A.gamba sp.nov.by the presence of a small spiniform process on the cymbium and a longitudinal black stripe on the dorsocentral red abdomen(Fig.B 1).The female resembles A.gamba sp.nov.by retaining the characteristic juvenile color pattern on the abdomen(Fig.B 2)and by the spermathecae shape(Fig.8).It can be distinguished from those of A.gamba sp.nov.by having spermathecae with a multilobular apex(Fig.8)and a single red spot inside the central longitudinal black stripe on dorsal abdomen(Fig.B 2).
Etymology
Etymology:The specific name refers to the type locality,the Reserva Biologica de Sooretama.

Genitalia:Two spermathecae,at basal third curving to external side in90°angle,having folds in two thirds of distal part and ending in multilobular apex(Fig.8).

Color pattern ontogeny:Even though we examined only a few specimens in different stadia,the color pattern ontogeny of A.sooretama sp.nov.seems to be similar to that of A.diversipes(cf.Figs A 4─ A 5)and A.gamba sp.nov.(cf.Figs C 3─ C 5).The main difference in the color of the spiderlings is the shorter central long spot on the dorsal abdomen does not reach its most anterior portion(Fig.B 3)as in A.diversipes and A.gamba sp.nov.Other differences from A.diversipes are the lack of orange markings on the tarsi and metatarsi both in large juveniles and adults(Figs B 1─ B 3).Adult males of A.sooretama sp.nov.have a pinky sheen all over the body and present a longitudinal central black stripe over the red abdomen(Fig.B 1).Adult females of A.sooretama sp.nov.seem to retain the juvenile color pattern(Fig.B 2).
Distribution
