FIG. 10. —
Glyphiulus obliteratoides
n. sp.
, paratype ♀:
A
, telson, ventral view;
B
, midbody segment section;
C
, claw of midbody leg;
D
, claw. Scale bars: A, 0.2 mm; B, 0.5 mm; C, 0.05 mm; D, 0.02 mm.
ETYMOLOGY. — To emphasize the very close resemblance to
G. obliteratus
n. sp.
DIAGNOSIS. — Differs from congeners by the pigmented ocelli and body, coupled with the more distinctly undulate collum, the undivided crests, etc. (see also key below).
DESCRIPTION
Holotype
with 59p+1a+
T
, about
32 mm
long and
1.9 mm
wide; adult

(

) with 45-60p+2- 1a+
T
, length
22-35 mm
, width
1.3-1.9 mm
.
Coloration entirely pallid in young juvenile stadia, becoming marbled red-brown in adults, tergal crests dark castaneous brown; antennae, legs and venter light red-brown in adults. Adults with 7-9 blackish ocelli in a subtriangular eye patch.
Antennal sensilla, segment shape (
Fig. 10B
), tergal crests (including ozoporiferous ones) (
Figs 9
;
10B
), epiproct (
Fig. 9E, F
), paraprocts (
Fig. 9E
), male legs 2 and 3 (
Fig. 11D, E
), penes (
Fig. 11D
), gonopods (
Fig. 11G, H
) generally as in
G. obliteratus
n. sp.
, but antennae (
Figs 9A
;
11A
) slightly shorter, gnathochilarium (mentum divided, n = 3) (
Fig. 11B
) more polytrichous; collum (
Fig. 9A, B
) with 1a-4a+ma+4a-1a undulations at caudal margin, undulation ma being shortest; hypoproct (
Fig. 10A
) very faintly emarginate caudomedially, conspicuous pleurosternal crests on segments 2-4 wanting (
Fig. 9A
); tergal crests similarly low and undivided, even adding another lateral crest below ozoporiferous one, which is barely traceable as a low anterior tubercle, but anterior end of all dorsal crests broadened (
Fig. 9
); carinotaxy pattern thus 1/0+1+I/i+3+I/i+1+1/0 (
Figs 9C, D
;
10B
); a small accessory spine present at base of claw on legs 2 and 3 only (
Fig. 11D
), onward nearly missing (
Figs 10B
;
11F
); legs about as long as body diameter (
Fig. 10B
); male leg 1 with 5-segmented but shortened telopodites (
Fig. 11C
).

Glyphiulus obliteratoides
n. sp.
, paratype ♂:
A
, antenna;
B
, gnathochilarium;
C
, leg 1, frontal view;
D
, leg 2, caudal view;
E
, leg 3;
F
, leg 9;
G
, anterior gonopods, caudal view;
H
, right posterior gonopod, frontal view. Scale bar: A-F, 0.3 mm; G, H, 0.4 mm.
Head width = segment 2 = 6 <collum = 7(8)> segment 3 = 5 <7 <8 <9 <10 <11 = midbody segments; body gradually tapering toward telson. Postcollar constriction evident (
Fig. 9B
).
REMARKS
The samples contain five haplopodous juveniles with 30-33p+1-3a+T, each with the ozoporiferous tubercles fully developed only on segments 5 and 6. In general, even juveniles of later, diplopodous, stadia are easily recognised due to the ozoporiferous cones being especially well developed on segments 5 and 6 only.
In the absence of any troglomorphic traits, this species can only be considered troglophilic at most.
