Name

Type material

Holotype female: Mun. Zapotitlan de las Salinas, Puebla, México, 18°22'48.3"N, 97°30'23.9"W, 2473 m, 29.V.2005, U.O.G. Vázquez, under rock (CNAN sel_1005). Paratypes: Female, same data as holotype (CNAN sel_1002).

Other material examined

MÉXICO: Morelos: Cuernavaca, Colonia Chamilpa, University of Morelos, 18°58'45.84"N, 99°'39.17"W, 11.II.2005, 1850 m, U.O.G. Vázquez, on wall at night, 1p♂ (EME sel_1010); Cuernavaca, 1♀ - Muma (1953)[1] placed this specimen in Selenops gracilis (AMNH).

Etymology

The specific epithet comes from the Nahua goddess Malinalxochitl, the goddess of desert-dwelling snakes and arthropods, and refers to the type locality and the indigenous Nahua people of this species' distribution. It is to be treated as a noun in apposition.

Diagnosis

This species is most similar to Selenops gracilis, but the posterior sclerotized area is u-shaped, with the lateral indentations directed anteriorly, and the posteromedian area of the caudal margin is rounded, rather than pointed (Fig. 25). Internally, the posterodorsal fold is medially depressed and the internal ducts are branched (Fig. 26). Males unknown.

Remarks

As in other closely related species, there is some epigynal variation. The internal ducts and posterodorsal fold are uniform across specimens examined.

Very dark and over half of tibiae, making lighter area appear very light. Cephalothorax: 0.83 times longer than broad; fovea longitudinal, broad, very shallow. Eyes:AER nearly straight; PER recurved; PME larger than AME, PLE largest, ALE smallest; eye diameters, AME 0.20, ALE 0.13, PME 0.30, PLE 0.55; interdistances AME-PME 0.03, PME-ALE 0.25, ALE-PLE 0.48.

Legs:leg I much shorter than legs II, III and IV; leg formula unknown (at least one leg missing); scopulae present on tarsi of all legs and metatarsi of legs I and II; tarsi I-IV with strong claw tufts; pr claw toothed, rl claws with fewer teeth; spination: leg I, Fm pr 1–1–1, d 1–1–1, rl 1–1–1; Ti d 0, v 2–2–2; Mt v 2–2; leg II, Fm pr 1–0–0, d 1–1–1, rl 1–1–1; Ti v 2–2–2; Mt v 2–2; leg III, Fm pr 1–0–0, d 1–1–1, rl 1–0–1; Ti v 2–2–0; Mt v 2–1. Abdomen:without terminal setal tufts. Epigyne:lateral lobes indistinct, hyaline median field with median septum terminating at heavily sclerotized posterior margin, lateral indentations directed anteriorly, posteromedian area u-shaped, genital openings located at posterolateral margins of median septum, internally ducts located posteriorly, directed laterally, branched, large heavily sclerotized posterodorsal fold covering nearly all of the internal ducts, medially depressed, rounded anterolaterally (Figs 25–26). Dimensions: Total length 9.33. Carapace length 4.73, width 5.75. Sternum length 2.75, width 2.00. Abdomen length 4.60, width 5.50. Pedipalp: Fm 1.00, Pt 0.70, Ti 0.75, ta 1.45, total 3.90. Leg I: Fm 4.75, Pt 2.00, Ti 4.00, Mt 3.00, Ta 1.00, total 14.75. Leg II: Fm 5.75, Pt 1.50, Ti 4.75, Mt 3.50, Ta 1.50, total 17.00. Leg III: Fm 5.80, Pt 1.75, Ti 4.75, Mt 3.75, Ta 1.00, total 17.05.
