Type material: Male holotype from New Mexico, 4-5 miles N of Jemez, C.C. Hoff (AMNH). EXAMINED.

Etymology: The specific name is a patronym in honor of Dr. Pierre Paquin, arachnologist and cave biologist.

Diagnosis: Males are differentiated from all species in the genus by their elongated, L-shaped lamella characteristica (Fig. 439) and their squared and rugose cymbial tubercles (Fig. 440).

Description: Male: Total length 1.53; carapace length 0.70, width 0.58.

CEPHALOTHORAX: Carapace light yellow-orange, shiny, finely reticulate; margin suffused with dark gray; trident mark present. Sternum light yellow-orange, suffused with gray. Clypeus height 2. Chelicerae light yelloworange, with transverse dark gray suffused band, not excavated; seta-tipped tubercles absent; promargin four teeth, retromargin one denticle. Cheliceral stridulatory organ ~35 striae, well spaced slowly getting closer basally. ABDOMEN: Uniformly light to dark gray. LEGS: Light yellow; leg I total length: 2.58; leg III total length: 2.01; Tm I: 0.54, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis large, pointed and smooth; dorsal tibial apophysis large, rugose; two retrolateral trichobothria and one dorsal (Fig. 439). Cymbium triangular; glabrous depression present (Fig. 439); dorsal and ventral cymbial tubercles squared and rugose; prolateral notch medium (Fig. 440). Paracymbium apical pocket long, anterior pocket long and curved making a medium cover, posterior pocket absent (Fig. 439). Embolus tip pointed, no retrolateral extension; basally with rows of spines; ventrally with numerous small spines; Fickert’s gland absent; ventral lamella reduced or absent; thumb going slightly over the embolus proper (Fig. 441). Embolus proper set apically, dorsal part larger, not serrated with associated large prong (Fig. 441). Anterior terminal apophysis with wide tip and long protrusions plus two basal, small prongs; posterior terminal apophysis with elongated tip; lamella characteristica with small, pointed tip and rounded extension (Fig. 442).

Female: Unknown.
