Himalayana parbat Grismado , new species

Figures 79– 81 , 82E–F

TYPES: Male holotype from Nepal: Dhawalagiri: Parbat: zw. Deorali u. Chitre , 2700 m, May 1–2, 1995, J. Martens and W. Schawaller ( SGN PBI_OON 15983 ), two female paratypes with same data ( SGN PBI _OON 15729) ; one additional male paratype from Parbat Dist., Chitre, gebüschreiches Bachbett , 2400 m, May 4, 1980, Martens and Ausobsky ( SGN PBI _OON 15717) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males of H. parbat are almost indistinguishable from those of H. siliwalae , but are larger sized (total length>1.7 mm) and have a thickened palpal femur (fig. 81C, E); females are distinguished from all congeners by the anterior T-shaped sclerite, which has a narrow stalk and thin, longer, acute transverse extensions (fig. 82E).

DESCRIPTION: Male (holotype, PBI_OON 15983). Total length 1.86. Cephalothorax: Carapace pars cephalica strongly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, sides granulate; lateral margin rebordered; nonmarginal pars cephalica setae dark, needlelike, in U-shaped row; nonmarginal pars thoracica setae dark, needlelike; marginal setae absent. Eyes all subequal, PME circular, PLE circular; posterior eye row recurved from above, straight from front; ALE separated by more than their diameter, ALE–PLE separated by less than ALE radius, PME touching for less than half their length. Sternum longer than wide, precoxal triangles present, lateral margins unmodified, orange; setae evenly scattered. Mouthparts: chelicerae, endites, and labium orange; fangs directed medially. Abdomen: Book lung covers elliptical. Pedicel tube medium, unmodified. Dorsal scutum orange. Epigastric scutum not protruding. Postepigastric scutum orange. Setae of dorsum and epigastric and postepigastric light. Spinneret scutum without fringe of setae. Colulus represented only by 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, circular. Palp: femur enlarged; cymbium narrow in dorsal view; bulb pale orange; embolus flanked by one retrolateral and one prolateral accompanying laminae with filiform projections (more numerous in the latter, figs. 81C–E, 82F).

Female (paratype, PBI_OON 15729). Total length 1.76. As in male except as noted. Cephalothorax: Carapace pale orange. Eyes PLE–PME separated by less than PME radius. Palp without spines. Abdomen: Dorsum soft portions white. Dorsal scutum lightly sclerotized, covering more than 3/4 of abdomen. Epigastric scutum lightly sclerotized. Postepigastric scutum lightly sclerotized, not fused to epigastric scutum. Legs: Patella plus tibia I shorter than carapace. Leg spination as in male. Genitalia: Dorsal view: similar to those of H. siliwalae , but the anterior T-shaped sclerite has a narrower stalk and the thin transverse extensions are longer (fig. 82E).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Parbat District (Dhawalagiri, Nepal).
