Type material.

Holotype female: from a rocky outcrop at night at kilometer 13 along Carretera ALCOA, Pedernales, Dominican Republic, 18°01.962' N, 71°38.748' W, 24XI.2004, S. Crews, SCC04_079 (EME sel_166).

Other material examined.

DOMINICAN REPUBLIC: same data as holotype, 6 imm. (EME sel_148-149, 161-163, 165, 167); Boca de la Cañada off Hwy. Pedernales-Oviedo, 17°55'00.5"N, 71°30'03.4"W, 9.X.2006, 64 m, S. Crews, on rocks at night, SCC06_071, 5 imm. (CAS sel_629-631, MNHNSD 635-636).

Etymology.

The specific epithet refers to a locality where the species is found, La Boca de la Cañada. It is to be treated as a noun in appostion.

Diagnosis.

The females of Selenops bocacanadensis sp. n. are similar to S. insularis in size and coloration, but females can be distinguished by the epigynal plate, as it is not as straight along the posterior margin, the genital opening is more rounded, rather than v-shaped, the posterodorsal fold is smaller, and the internal ducts are shaped differently (Figs 127-128). Males unknown.

Description.

Holotype female: Color: Carapace uniformly brownish-red with white setae; sternum light orange-brown; chelicerae uniformly dark reddish-brown; maxillae light orange-brown, darker on outer distal edge, white on inner distal edge; labium orange-brown, lightening distally; abdomen dorsally grey-tan, dark festoon pattern caudally; ventrally dusky grey with no markings; legs: femora red-brown with darker annulations, hardly visible, patella to tibia very dark (black in live specimens). Carapace:0.91 times longer than broad. Eyes:AER nearly straight; PER recurved; PME larger than AME, PLE largest, ALE smallest; eye diameters, AME 0.38, ALE 0.13, PME 0.48, PLE 0.55; interdistances AME-PME 0.10, PME-ALE 0.13, ALE-PLE 0.60. PME-PME 1.68 mm. ALE-ALE 2.85; ocular quadrangle AME-AME 0.60, PLE-PLE 2.98; clypeus 0.09 high. 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 only slightly shorter than legs II, III and IV; leg formula 2341; legs I and II with tarsal and metatarsal scopulae; tarsi I-IV with strong claw tufts; claws without teeth; spination: leg I, Fm pr 2 –1– 0, d 1 –1– 1, rl 1 –1– 1; 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 –1– 1; Ti v 2 –2– 0; Mt v 2-2; leg IV, Fm pr 1 –0– 0, d 1 –1– 1, rl 0 –0– 1; Ti v 2 –2– 0; Mt v 2-2. Abdomen:without terminal setal tufts. Pedipalp:claw with 11 teeth. Epigyne:lateral lobes abut one another, ¾ the length of plate, extending from caudal margin to bottom of genital opening; opening small, slightly ovoid, epigynal pockets present; caudal margin sinuous, lobes extend posteromedially; internally, sperm ducts extend posteriorly, then separate laterally to oblong, cylindrical spermathecae, the fertilization ducts located laterally, directed anterolaterally, posterodorsal fold small, sinuous, does not completely cover spermathecae (Figs 127-128). Dimensions: The abdomen was damaged during collection, however, the specimen falls on the larger end of the spectrum for this genus (>10.00). Carapace: length 5.25, width 5.75. Pedipalp: Fm 2.00, Pt 0.30, Ti 0.75, Ta 1.75, total 4.80. Leg I: Fm 6.00, Pt 2.00, Ti 6.00, Mt 4.25, Ta 2.00, total 20.25. Leg II: Fm 8.00, Pt 2.25, Ti 6.50, Mt 5.00, Ta 2.00, total 23.75. Leg III: Fm 7.75, Pt 2.00, Ti 6.00, Mt 5.00, Ta 2.00, total 22.75. Leg IV: Fm 6.50, Pt 2.00, Ti 5.75, Mt 5.75, Ta 2.00, total 22.00.
