Escaphiella cachimbo , new species Figures 675–696 ; map 14

TYPE: Female holotype from Campo de Provas Brigadeiro Velloso , Serra do Cachimbo, 9 ° 219890S, 55 ° 029010W, Novo Progresso, Pará, Brazil (A. Bonaldo, D. Santos-Souza, D. Guimarães; Sept. 7–17, 2003), deposited in MPEG (11711, PBI_OON 29510) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Females of this species can easily be recognized by the epigynal atrium, which has rebordered anterior and lateral (but not posterior) margins, and which has a distinct anterior, procurved depression (figs. 690, 695); males resemble those of E. aratau but have an embolus that is more distinctly bent near the tip (figs. 683–687).

MALE (PBI_OON 29509): Total length 1.15 (fig. 675). Carapace pale orange, surface of elevated portion of pars cephalica smooth, sides granulate, with obvious granulations restricted to pars cephalica margins, almost reaching apex on pars thoracica; lateral margins without denticles (figs. 676, 679). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 678). Sternum pale orange, with radial furrows between coxae I–II, II–III, III– IV, furrow smooth, surface smooth, microsculpture absent (fig. 681). Chelicerae, endites, and labium pale orange. Endites anteromedially modified, with spiniform tip. Abdomen ovoid; book lung covers large, ovoid; pedicel tube medium, ribbed, scutum extending far dorsal of pedicel, long scutal ridge situated far above pedicel (fig. 688); dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above, middle surface smooth, sides smooth; postepigastric scutum pale orange, sides smooth (figs. 677, 680, 682). PMS present (compound microscope). Legs pale orange. Right and left palps symmetrical, proximal segments pale orange; embolus dark, distinctly bent near tip (figs. 684–687); femur normal size (fig. 683); cymbium and bulb pale orange.

FEMALE (PBI_OON 29511): Total length 1.17 (figs. 690, 693, 694, 696). Abdomen with soft portions of dorsum white (fig. 689, 691, 692). Epigynal atrium with anterior, procurved depression (fig. 695).
