Laos
; adjective.
Diagnosis:
Notiocoelotes laosensis
sp. nov.
resembles
N. vietnamensis
sp. nov.
from
Vietnam
in having distinct, long spermathecal heads but can be easily distinguished by the relatively small, distinctly separated copulatory ducts (
Figs 1–2
,
8
), whereas
N. vietnamensis
sp. nov.
has large, medially adjacent copulatory ducts.
Description:
Female
holotype
: Small sized coelotine, total length 4.32. Dorsal shield of prosoma 1.92 long, 1.44 wide; opisthosoma 2.40 long, 1.60 wide. Body pale, without distinct color pattern (
Figs 3
,
6
). Eye sizes and interdistances: anterior row with only two eyes, AME absent, other eyes subequal (AME missing, ALE 0.10, PME 0.08, PLE 0.10); ALE and PME slightly separated, other eyes distinctly separated (ALE– ALE 0.12, ALE–PLE 0.04, PME–PME 0.06, PME–PLE 0.04) (
Figs 4
,
7
). Chelicera with 3 promarginal and 2 retromarginal teeth. Legs slightly long and slender comparing to other coelotines, with length of first leg about 5.67 times dorsal shield of prosoma length (I 10.88; II 8.48; III 7.52; IV 10.56). Epigynum without teeth; atrium small, length subequal to width, with distinct scape on posterior edge; copulatory ducts large, rounded, folded posterolaterally; spermathecae small, widely separated; spermathecal heads long, strong, extending anteriorly and covered by copulatory ducts from dorsal view (
Figs 1–2
,
8
).
Male: Only immatures were collected, adults are unknown.
Habitat:
The spider was collected from a limestone cave in a Karstic region.
Distribution:
Laos
(Khammouan) (
