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).
Male: Unknown.
OTHER MATERIAL EXAMINED: None.
DISTRIBUTION: Known only from a single cave in the
type
