Etymology.
This species is named in honor of Denia Veloz for all of her work on arthropod biodiversity in the Dominican Republic. It is to be treated as a noun in apposition.
Diagnosis.
Males can be separated from all other species by the conductor which arises anteromedially on a short stalk with a rounded projection. The conductor is directed opposite the RTA and is hammer shaped (Figs 135-136). Females unknown.
Description.
Holotype male: Color: carapace brownish-orange; sternum, brownish-yellow, darker around border; chelicerae dark red-brown; maxillae light orange-brown, lightening distally; labium orange-brown, lightening toward distally edge; abdomen dorsally brownish-orange, dark at anterior margin, lanceolate stripe extending nearly 3/4th the length of abdomen, line extending across entire abdomen below stripe, laterocaudal festoon present; ventrally yellow-grey, darker laterally; legs yellowish-brown to orange-brown, darkening slightly distally, annulations conspicuous on femora, patellae and tibiae. Carapace: as long as broad; fovea, longitudinal, narrow, shallow. Eye: AER nearly straight; PER slightly recurved; PME the same size as AME, PLE largest, ALE smallest; eye diameters, AME 0.40, ALE 0.23, PME 0.40, PLE 0.55; interdistances AME-PME 0.10, PME-ALE 0.20, ALE-PLE0.40, PME-PME 1.15, ALE-ALE 2.30; ocular quadrangle AME-AME 0.20, PLE-PLE 2.35; clypeus 0.10 high; chillum absent. Mouthparts: chelicerae with stout setae medially and anteriorly; maxillae longer than broad with tuft of conspicuous setae distally; labium distally rounded. Sternum: as long as broad, posteriorly indented. Legs: leg I much shorter than leg II and slightly shorter than leg III; leg formula 2314; scopulae present on all 4 tarsi; tarsi I-IV with strong claw tufts; pr claw per foot slightly toothed; spination: leg I, Fm pr 1-1-0, d 1-1-1, rl 1-1-1; Ti d 0, v 2-2-2; Mt v 2-2; leg II, Fm pr 1-1-1, d 1-1-1, rl 1-1-1; Ti v 2-2-2; Mt v 2-2; leg III, Fm pr 1-1-0, d 1-1-1, rl 0-1-1; Ti v 2-2; Mt v 2-2; leg IV, Fm pr 1-1-0, d 1-1-1, rl 0-0-1; Ti v 1-1; Mt v 2-1. Abdomen: without terminal setal tufts. Pedipalp: Fm spination 0-1-3; cymbium oval in ventral view, slightly angled posterolaterally; basal cymbial process absent, scopulae scattered, denser distall; conductor arising anterolaterally on short stalk with rounded lateral projection, hammer shaped, directed opposite RTA, forming circular space between hammer shape and stalk, embolus shorter, slender, directed
anteriorly
, straight, arising at 6 o'clock, terminating at 11 o'clock; MA wider at base, narrowing, curving into small hook, originating at 4 o'clock, directed anterolaterally; RTA barely reaching cymbium in ventral view; posterior branch directed anteriorly, quadrangular, truncate terminally; ventral branch quadrangular in ventral view, flattened in lateral view; RTA looks u-shaped in lateral view (Figs 135-136). Dimensions: Total length 9.50. Carapace length 5.00, width 5.00. Sternum length 2.00, width 2.00. Abdomen length 4.50, width 4.00. Pedipalp: Fm 1.75, Pt 1.00, Ti 1.00, Ta 1.30, total 5.05. Leg I: Fm 7.00, Pt 2.00, Ti 6.00, Mt 5.00, Ta 2.50, total 22.50. Leg II: Fm 7.00, Pt 2.50, Ti 6.75, Mt 6.00, Ta 2.75, total 25.00. Leg III: Fm 7.00, Pt 2.00, Ti 6.00, Mt 5.50, Ta 2.50, total 23.00. Leg IV: Fm 6.00, Pt 2.00, Ti 5.00, Mt 5.00, Ta 2.00, total 20.00.
Natural history.
This species has been collected under bark and on buildings and fence posts at night, primarily at higher elevations (> 550 m).
Distribution.
Endemic to the Dominican Republic, though seems to be widespread across the country (Map 13).
