| Popis: | Acanthoctenus kollari (Reimoser, 1939) Figs 10A, 29–30 Phymatoctenus kollari Reimoser, 1939: 369, fig. 9 (female holotype from Reventazón River, Cartago [9°51’54.8”N, 83°44’09.8”W], Costa Rica, deposited in HMW 9276, examined).— World Spider Catalog 2020. Paracantheis kollari — Kraus 1955: 51 (Trans.). — World Spider Catalog 2020. Acanthoctenus kolleri (lapsus)— Lehtinen 1967: 208, 259 (Trans.).— World Spider Catalog 2020. Diagnosis. Females of Acanthoctenus kollari (Figs 29, 30 D–E) resemble those of A. chickeringi sp. nov. (Figs 39 C–D, 40D, 41) by the atrium with two strongly scletotized anterior borders, and the copulatory ducts bended anteriorly. It can be distinguished by the atrium subtriangular, and the median sector wider anteriorly, as wide as the margins of its lateral extensions. A. chickeringi sp. nov. presents a subquadrangular atrium, and an anterior thin median sector, half the width of the margins of its lateral extensions. Description. Male. Unknown. Female (holotype HMW 9276). Total length 13.00. Carapace 6.00 long, 5.00 wide. Clypeus 0.30 high. Eye diameters: AME 0.30, ALE 0.23, PME 0.30, PLE 0.37 Leg measurements: I: femur 7.00/ patella 4.00/ tibia 7.80/ metatarsus 6.20/ tarsus 2.00/ total 27.00; II: 6.20/ 3.00/ 6.00/ 5.20/ 2.00/ 22.40; III: 5.50/ 2.20/ 5.20/ 7.20/ 2.20/ 22.30; IV: 6.50/ 2.30/ 6.00/ 7.60/ 2.20/ 24.60. Leg formula 1423. Leg spination: tibia I and II v-2-2-2-2-2-2-2-2-2, p-2-2-1, r-1-0-1-1-1, III v-2-2-2, p-1-0-1-1, r-1-0-1-1, IV v-2-2-2, p-1-1, r-1.1; metatarsus I and II v-2-2-2-2-2, p-1, r-1 III v-1-1-1, p-1-1-1-1, r-1-1-1-1, IV v-1-1-1-1, p-1-1-1, r-1-1-1. Epigynum (Figs 29 A–B, 30D–E): median sector subpentagonal, as wide as long, wide anteriorly and extending into the atrium, projected posteriorly; anterior border of the lateral sectors straight; atrium large, subtriangular; copulatory ducts bended, S-shaped; spermathecae head quote-shaped, with apical glandular openings, spermathecae base curled; fertilization ducts tubular, slanting outwards. Distribution. Costa Rica (Fig. 10A).
