description: Goeldia goytacazes sp. nov.
(Figs 12; 27)
Type material. Holotype male, paratype female from Campos de Goytacazes (21°45’14”S 41°19’26”W), Rio de Janeiro, Brazil, 24.IX.2003, C.C.L. Teixeira coll., deposited at MCN 39868; Paratype female with same data as holotype, deposited at MCN 43434.
Additional material examined. None.
Etymology. The specific name is a noun in apposition in honor to the indigenous people of the Goytacazes tribe, who lived in the type locality.
Diagnosis. Goeldia goytacazes resembles G. mirim by the general shape of the male palp and epigynum (Fig. 16), but differs by the patellar apophysis pointing posteriorly (Fig. 12C); by the enlarged base of the MLT (Fig. 12C) and tegular process lanceolate (Fig. 12A) in the male palp. The female epigynum is also similar but in G. goytacazes it covers almost completely the copulatory duct wall (Fig. 12E) and the vertical spermathecae is much shorter than the copulatory duct (Fig. 12F).
Description. Male (Holotype). Coloration: carapace dark brown. Sternum and labium black, endites brown. Leg coxae and femora black, other leg segments yellowish brown except distal half of patella and tibia III and IV black and metatarsus IV grayish. Opisthosoma grayish brown. Total length 3.15. Carapace: lenght 1.59; width 1.16; height 0.75. Opisthosoma: length 1.65; width 1.38. Clypeus: height 0.13.

Leg spination: femur I pap; tibia I v1r-2(1r- 1m)- 2(1r- 1m)-0, p0-1-0, r0-1-0-1-0; III–IV: p1ap, r1ap; metatarsus I v1r-1r- 1m, p1ap, r1ap; II v1r-0-1r- 1m, p1ap, r1ap; IV v1r-1p-1map, p0-1-1ap, r1ap. Patellar apophysis pointing dorsally and posteriorly (Fig. 12C–D). RLT with an extra basal fold (Fig. 12C). Tegular process as in illustration (Fig. 12A). Pars pendula thickening subdistal (Fig. 12D).
Female (Paratype): Coloration as in male except, femora black, tarsus I and II reddish brown and other leg articles yellowish brown. Total length 3.84. Carapace: length 1.80; width 1.24; height 0.75.
