Wang, Xin-Ping, Xu, Xiang & Li, Shuqiang, 2008, Notiocoelotes, a new genus of the spider subfamily Coelotinae from Southeast Asia (Araneae, Amaurobiidae), Zootaxa 1853, pp. 1-17 : 7-8

Notiocoelotes lingulatus sp. nov.

Figs 9–16 , 44

Type material: Holotype female: China, Hainan Province, Diaoluoshan Mt., N18.7º, E109.8º, December 23, 1989 ( IZCAS).

Etymology: The species name is derived from the Latin “ lingulatus ”, meaning tongue-shaped, and refers to the tongue-shaped atrial scape; adjective.

Diagnosis: Notiocoelotes lingulatus sp. nov. resembles N. palinitropus from Hainan, China in having the strongly folded copulatory ducts and the small spermathecal heads but can be easily distinguished by the short, square-shaped atrium and the distinctly separated, semi-circular copulatory ducts ( Figs 9–12 ), whereas N. palinitropus has a strongly elongated atrium and large, fused, anteriorly extending copulatory ducts.

Description: Female holotype: Small sized coelotine, total length 4.20. Dorsal shield of prosoma 1.90 long, 1.40 wide; opisthosoma 2.30 long, 1.65 wide ( Figs 14–16 ). Eye sizes and interdistances: AME smallest, approximately half the size of other eyes which are subequal and clustered (AME 0.06, ALE 0.10, PLE 0.12, PME 0.12); AME–PME separated by approximately PME diameter ( Fig. 13 ). Chelicera with 3 promarginal and 2 retromarginal teeth. Legs normal length (I 5.50; II 4.80; III 4.50; IV 5.95) (1st leg/dorsal shield of prosoma = 2.90). Epigynum without teeth; atrium small, length and width subequal; atrial scape distinct, situated on posterior atrial edge; copulatory ducts large, anteriorly originating, extending and folding posteriorly semi-circular; spermathecae small, widely separated; spermathecal heads long, extending posteriorly, covered mostly by copulatory ducts and only their distal parts visible from dorsal view ( Figs 9–12 ).

Distribution: China (Hainan) ( Fig. 44 ).
