Figures 13 , 14D

TYPES: Female holotype from India: Meghalaya: Jaintia Hills, near Musianglamare , cave Synrang Pamiang , cave, 25.21333 ° N, 92.36333 ° E, Feb. 16, 1999, Christian Fischer ( NMB Ar 2548 PBI_OON 30637 ) ; deposited in NMB.

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

DIAGNOSIS: The female of D. synrang resembles those of D. typhlos by its large size and well-sclerotized teguments and by having a small dorsal abdominal scutum and two transverse genital plates (figs. 13A, H, 14D), but differs by the T-shaped anterior genital sclerite narrower anteriorly and by the elongated tracheal spiracles (figs. 13H, 14D).

DESCRIPTION: Female (holotype, PBI_ OON 30637). Total length 2.26. Cephalothorax: Carapace pale orange, nonmarginal pars cephalica setae light, needlelike, in three rows; nonmarginal pars thoracica setae light, needlelike. Clypeus vertical in lateral view; setae absent. Remnants of eyes visible beneath the cuticle (fig. 13G). Sternum pale orange, posterior margin extending posteriorly beyond anterior edges of coxae IV as single extension; setae dark, evenly scattered. Mouthparts: chelicerae, endites, and labium pale orange. Cheliceral setae light; paturon inner margin unmodified. Labium anterior margin deeply incised (fig. 13E). Abdomen: Dorsum soft portions pale orange. Book lung covers round. Pedicel tube medium sized, ribbed. Dorsal scutum weakly sclerotized, pale orange, without color pattern, covering less than 1/2 of abdomen, between 1/4 and 1/2 of abdomen width. Postepigastric scutum pale orange. Spinneret scutum present, incomplete ring. Dorsum setae light. Epigastric area setae dark. Postepigastric area setae dark. Spinneret scutum with fringe of stout setae. Legs: Pale orange. Leg spination (all spines longer than segment width): leg I: femora pv0-1-0, tibiae v2-2-2-2-0, metatarsi v2-2-0; leg II: tibiae v2-2-2-2-0, metatarsi v2-2-0; leg III: tibiae p1-1, v2ap, metatarsi p1-1; leg IV: tibiae p1-1, v2ap, metatarsi p1-1. Tarsi I–IV superior claws tooth not examined in detail. Trichobothria not examined. Genitalia: Two procurved, transverse, well-sclerotized plates, posterior one with short lateral apodemes; anterior sclerite long, less widened anteriorly than in D. typhlos ; posterior receptacle small, round; copulatory opening inconspicuous (figs. 13H, 14D).
