Material examined. " Paratype ♀, Cayenne, Iles de Salut, K. Jelski, M. Warszawa". Label appears to refer to the syntype female from a series of 2 ♀ and 2 ♂ belonging to the Museum and Institute of Zoology, Polish Academy of Sciences, Warsaw. Note. The species is transferred to Corinnidae and not to the similar looking Trachelidae because it has numerous and well-developed spines, which are generally lacking in Trachelidae. Amaurobius rufipes does not fit into any genus presented in a key of the Neotropical Corinninae (Bonaldo 2000). We decided to provisionally place A. rufipes in Abapeba Bonaldo, 2000 due to similarities of the endogyne of A. rufipes and A. rioclaro Bonaldo, 2000, although A. rufipes lacks clavate hairs covering the body.
Diagnosis. The epigyne of A. rufipes is most similar to that of A. rioclaro (cf. Bonaldo 2000: figs. 200–201), although it differs by having a distinct anterior pocket, notch at the posterior margin (lacking in A. rioclaro) and shorter anterior receptacles.
Description. Female. Total length 8.55. Carapace 3.83 long, 3.15 wide. Carapace brown without pattern (Fig. 1). Chelicerae light brown, anterior margin with 3 teeth, posterior margin with 5 teeth (Fig. 2). Sternum, maxillae and labium light brown (Fig. 2). Dorsum of abdomen yellowish, grayish laterally and ventrally (Fig. 1). All leg segments uniformly yellowish-brown. Spination: leg I: femur 2 d, 1 p; tibia 4- 5 v, 2 a; metatarsus 2 - 2 v; leg II: femur 2 d; tibia 2- 3 v, 2 a; metatarsus 2 - 2 v; leg III: femur 2 d, 2 p, 1 (2)r; tibia 2 p, 2 r, 2 - 2 v, 2 a; metatarsus 1 p, 1 r, 2 - 2 v, 2 a; leg IV: femur 3 d, 1 r; tibia 3 p, 2 r, 2 - 1 v, 2 a; metatarsus 1 p, 2 r, 2 - 2 v, 2 a. Spines shorter than the diameter of the leg joints (Fig. 1). Spinnerets (Fig. 3), colulus large. Epigyne (Figs 4–10); epigynal plate lies in two plains: with ventral part visible in intact specimen (Fig. 4) and posterior part inside epigastral fold visible on dissected epigyne (Figs 9–10). Epigynal plate with distinct anterior (Ap) and posterior (Pp) pockets; anterior pocket bell-shaped, deep, with copulatory openings inside, with a nearly straight margin. Central part of plate with a shallow cavity (Mc) below anterior pocket; cavity with transverse ridges. Lateral sides of epigynal plate with two shallow cavities (Lc). Posterior pocket located above notch (No) and between two lateral lobes (Ll); in ventral view, pocket is hidden by a plate and only visible as a translucent dark spot. Copulatory openings lead to a short part of the fertilization duct (Fd) that is sclerotized, followed by a short, weakly sclerotized part. Receptacles are complex, each with two chambers, both weakly sclerotized: anterior chamber is bean shaped (Re1) and posterior chamber is round (Re2). Anterior chamber is at the sides of the anterior pocket. Fertilization duct (Fd) originates from the posterior chamber. Leg joint measurements (femur + patella + tibia + metatarsus + tarsus): I 10.75 (3.0 + 1.5 + 2.8 + 2.45 + 1.0), II 9.7 (2.85 + 1.4 + 2.45 + 2.1 + 0.9), III 8.7 (2.45 + 1.1 + 2.05 + 2.25 + 0.85), IV 12.05 (3.25 + 1.45 + 3.0 + 3.35 + 1.0).
Comments. Because A. rufipes is here transferred to Abapeba, and both Simon (1898) and Lehtinen (1967) believe that all Amaurobius described by Taczanowski (1874) from Guyana are congeneric, we also transfer three other species known from holotype females to Abapeba and establish the following new combinations: Abapeba brevis (Taczanowski, 1874)comb. n., Abapeba cayanus (Taczanowski, 1874)comb. n., and Abapeba hirtus (Taczanowski, 1874)comb. n. (all ex- Amaurobius).
