Jäger leg. ( SMF). 1 female paratype from Laos, Khammouan Province, 2.5 km WNW Ban Tathot, entrance N17°37.897', E105°07.502', exit N17°37.994', E105°07.195', ca. 200 m alt., entrance area and in the Karst cave Tham Kamouk, February 19, 2003, P. Jäger leg. ( SMF). 1 female paratype from Laos, Khammouan, 2.5 km WNW Ban Tathot, entrance N17°37.897', E105°07.502', exit N17°37.994', E105°07.195', ca. 200 m alt., entrance area and in the karst cave Tham Kamouk, February 19, 2003, H. Steiner leg. ( SMF).

Additional material examined: 1 juvenile male and 1 juvenile female, in same vial as holotype ( SMF); 3 juvenile females from Laos, Khammouan Province, 2.5 km WNW Ban Tathot, entrance N17°37.897', E105°07.502', exit N17°37.994', E105°07.195', ca. 200 m alt., entrance area and in the karst cave Tham Kamouk, February 19, 2003, H. Steiner leg. ( SMF).

Etymology: The specific name refers to the type locality of the species, 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) ( Fig. 44 ).
