TYPES: Male holotype from Nepal: Mechi: Ilam: Mai Pokhari , Castanopsis forest remnant, 2200 m, Apr. 9–10, 1988, J. Martens and W. Schawaller ( SGN PBI_OON 15978 ) . Three female paratypes with same data ( SGN PBI_OON 15747 ) .

ETYMOLOGY: The specific name is a noun in apposition referring the dominant trees in the forest where the types were collected.

DIAGNOSIS: Males of this species are easily recognizable by the conspicuous bunch of dark, thickened setaelike projections on the prolateral base of the embolus (figs. 71D–E, 72F). Females are distinguished by the very short lateral branches of the anterior sclerite, with rounded endings (fig. 72E).

DESCRIPTION: Male (holotype, PBI_OON 15978). Total length 1.60. Cephalothorax: Carapace pars cephalica slightly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, sides granulate; lateral margin rebordered; non-marginal pars cephalica setae needlelike, in U-shaped row; nonmarginal pars thoracica setae needlelike; marginal setae needlelike. Eyes all subequal, PME circular, PLE circular; posterior eye row straight from above, procurved from front; ALE separated by their radius to diameter, ALE–PLE touching, PME touching throughout most of their length. Sternum longer than wide, lateral margins unmodified, orange; setae evenly scattered. Cheliceral fangs directed medially. Abdomen: Dorsum soft portions not visible. Book lung covers round. Pedicel tube short. Dorsal scutum orange. Epigastric scutum not protruding. Postepigastric scutum orange. Dorsum setae dark. Postepigastric area setae dark, with enlarged forwardly directed setae, converging with similar epigastric setae around the furrow connecting the posterior spiracles. Spinneret scutum with fringe of needlelike setae. Colulus present, with two needlelike setae. Legs: Pale orange. Leg spination (all spines longer than segment width): leg I: tibiae v2-2-2-2-0, metatarsi v2- 2-0; leg II: tibiae v2-2-2-2-0, metatarsi v2-2-0. Tarsi I–IV superior claws tooth not examined in detail. Trichobothria not examined. Genitalia: Epigastric region with sperm pore small, oval, unmodified. Palp:femur normal size, slightly thickened; cymbium narrow in dorsal view; bulb yellow-brown, distal part with a prolateral bunch of many stout tickened, dark setaelike projections (figs. 71 D–E, 72F).

Female (paratype, PBI_OON 15747). Total length 1.76. As in male except as noted. Cephalothorax: Eyes PLE–PME separated by less than PME radius. Palp without spines. Abdomen: Dorsal scutum less sclerotized, covering more than 3/4 of abdomen. Epigastric and postepigastric scuta not strongly sclerotized, not fused. Legs: Patella plus tibia I shorter than carapace. Leg spination as in male. Genitalia: Copulatory opening not visible; anterior sclerite with very short lateral transverse projections with rounded endings (fig. 72E).
