Ordo: Araneae
Familia: Euctenizidae
Genus: Eucteniza
Name
Eucteniza golondrina Bond & Godwin, 2013 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Male holotype (UMM117) from Sótano de las Golondrinas, Aquismón, San Luis Potosí, Mexico, 21.6263, -99.02924, elev. 164m, coll. A. G. Grubbs xi.1987, deposited in AMNH.
Etymology
The specific epithet is a noun taken in apposition and is in reference to the type locality Sótano de las Golondrinas (= Cave of Swallows).
Diagnosis
The male Eucteniza golondrina type specimen differs from all other species of Eucteniza by virtue of a distinct leg I morphology that includes a unique group of distal spines on the ventral surface of metatarsus I (Figs 69, 70, 73); the palpal tibia of Eucteniza golondrina also has a retrolateral distal row of spines that is lacking in all other known species (Figs 72, 73).
Description of male holotype
Specimen preparation and condition. Specimen preserved in 70% EtOH. Pedipalp, legs I, II removed, stored in vial with specimen. Color faded. General coloration. Carapace dark reddish brown 2.5YR 2.5/4. Abdomen black 10YR 2/1. Cephalothorax. Carapace 8.478 long, 7.437 wide, sparsely setose, few heavy setae posteriorly, pars cephalica slightly elevated. Fringe of sparse, heavy setae at posterior corners of carapace. Foveal groove deep, procurved. Tubercle absent. AER straight. PER straight. AME slightly larger in diameter than PME. Sternum moderately setose, STRl 4.695, STRw 3.874. Posterior sternal sigilla very large, not contiguous, tapering posteriorly, anterior sigilla pairs small and marginal. Chelicerae with anterior tooth row comprising 11 large teeth, posterior margin with single row of 14 small teeth. Palpal endites with few cuspules across endite face, labium lacking cuspules, LBw 1.377, LBl 0.758. Rastellum consists of 4 small spines. Abdomen. Moderately setose. Legs. Leg I: 8.354, 4.595, 6.006, 5.792, 3.034; leg IV: 8.586, 4.081, 6.970, 7.841, 4.161. Dense scopulae on legs I-II. Tarsus I with wide band of approximately 23 trichobothria. Leg I spination pattern; TSp 8, TSr 0, TSrd 0 (Figs 69, 70, 73); Leg II spination Fig. 71. Pedipalp. PTw 1.877, PTl 3.729, Bl 1.556.
