Diagnosis.
A
Cryptops
species
, about
2 cm
long with antenna extending back to tergite 6; incomplete paramedian sutures on cephalic plate; anterior transverse suture on tergite 1; labrum tridentate; prefemur and femur of ultimate leg at least 4 times longer than wide, femur and tibia of ultimate leg lacking distal spinose processes; tibia with 7, tarsus 1 with 4 saw teeth.
Description.
Length
19 mm
(
holotype
). In ethanol stored specimen, head pale yellow and trunk (including legs) whitish with pale yellow posteromedian parts of tergites (
Fig. 2
).
Length and width of cephalic plate nearly equal (
1.2 mm
), posterior corners rounded, sides weakly convex outwards for much of their length; two paramedian sutures on cephalic plate are incomplete, expressed anteriorly and posteriorly up to one fourth of cephalic plate length only. Antennae
7 mm
long (
holotype
), with 17 elongated articles; basal article stout, articles then gradually increasing in length to a maximum along articles 6–14 (ca 2 times longer than their width), then gradually shortening along articles 15–17. Articles 1–3 bearing strong setae of various length, these setae round proximal end of articles 4–5; from article 6, short fine setae form a fur-like covering.
Clypeus well defined anteriorly, with a triangular group of about 16 setae (
Fig. 4
), about 10 of them arranged in line along the posterior border. Labrum with side-pieces notched at their medial angle, tridentate, although the middle tooth is shorter (
Fig. 4
).

with the speleologist descending.
Forcipular coxosternum with anterior edge slightly rounded with weak median notch (
Fig. 3
). Coxosternum bearing only a few sparse, moderately long or short setae. Trochanteroprefemur scattered with long, fine setae. Tarsungulum long, slender. Apical claw of second maxilla with slender hook and a flange along its inner edge. Dorsal brush dense, running along distal two-thirds of article 3.
Tergites 2–7 broader than long, tergites 8–19 longer than broad. Overlap of tergite 1 by cephalic plate hides complete anterior transverse suture. Tergites 2–20 with anterior transverse suture hidden by preceding tergite. Tergites 3–20 with longitudinal paramedian sutures; oblique lateral sutures on tergites 3–5. Tergite of ultimate legbearing segment slightly longer than wide, posterior margin rounded; shallow longitudinal median depression on its posterior half. Sternites sparsely scattered with moderately long, thin setae. Posterior margin of sternite of ultimate leg-bearing segment rounded.
Legs relatively long and slender. All tarsi strongly bipartite. All legs covered by sparse long setae, ventral face of tarsi with row of slender setae. Pair of accessory spurs half-length of pretarsus on legs 1–20. Ultimate leg of
holotype
(
Fig. 8
): prefemur
1.5 mm
long, femur
1.2 mm
, tibia
0.8 mm
, tarsus 1
0.6 mm
, tarsus 2
0.9 mm
; prefemur and femur ca 4 times and 5 times longer than their maximal widths at distal ends, respectively. Robust setae on anterior, posterior and ventral sides of prefemur and femur, mostly slender setae on dorsal side; tibial and tarsal setae slender; 7 saw teeth on tibia, 4 on tarsus 1 (
Fig. 9
, the same situation on
paratypes
); inner margin of tarsus 2 a ridge. Apical claw well developed, without basal sensory spur.
Coxopleural pore field elliptical, with ca 35–40 pores and 4–5 slender, short setae interspersed among the pores.
Etymology.
The specific name originates from the
type
locality.
Distribution.
The new species is known from the
type
locality only. Probably it can be found in the neighbouring caves.
