Escaphiella pocone , new species Figures 750–797 ; map 15

TYPES: Female holotype and male allotype taken by fogging at Fazenda Retiro Novo, Pocone´, Mato Grosso, Brazil (I. Marques; 2003), deposited in IBSP (67028, PBI_OON 27744) .

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

DIAGNOSIS: This species resembles E. aratau in having a patterned abdomen, but males have an embolus bent at about half its length (figs. 781–784) and females have a very narrow anterior epigynal sclerite (fig. 795).

MALE (PBI_OON 27740): Total length 1.57 (figs. 772, 773, 778). Carapace pale orange, surface of elevated portion of pars cephalica smooth, sides smooth, granulate microsculpture along margins and surface of pars thoracica nearly reaching apex; lateral margins with blunt denticles (figs. 750, 774, 780). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 776). Sternum pale orange, with radial furrows between coxae I– II, II–III, III–IV, furrow smooth, surface smooth, microsculpture absent (figs. 752, 785). Chelicerae (figs. 753, 754), endites,

and labium (fig. 755) pale orange. Endites anteromedially modified, with thickened, rounded tip (figs. 757–761). Abdomen ovoid; striped pigmentation visible under dorsal scutum; book lung covers large, ovoid; pedicel tube medium, ribbed, scutopedicel region unmodified, scutum extending far dorsal of pedicel (figs. 777, 786), sperm pore flanked with pair of depressions (figs. 762, 779); dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above, middle surface smooth, sides smooth (fig. 751); postepigastric scutum pale orange, sides smooth (fig. 775). PMS present (figs. 763, 764). Legs pale orange. Right and left palps symmetrical, proximal segments pale orange; embolus dark, embolus thick, bent at half its length (figs. 781–784); femur normal size; cymbium and bulb pale orange.

FEMALE (PBI_OON 27740): Total length 1.62 (figs. 765–770, 789, 790, 793, 794, 796, 797). Abdomen with soft portions of dorsum white, with striped pigmentation (figs. 787,

788, 791). Epigynum with very narrow anterior sclerite (figs. 771, 792, 795).
