Notiocoelotes vietnamensis sp. nov. , female paratype from Huong Son, Vietnam. 38 Colulus, representated by setae (indicated by arrows); 39 PMS; 40 PLS; 41 Tarsus of the fourth leg, showing position of tarsal organ and trichobothria. AC = aciniform gland spigots; CY = cylindrical gland spigots; mAP = minor ampullate gland spigot. Diagnosis: Males of this new species are similar to N. palinitropus in having a long, coiled conductor but can be distinguished by the presence of a large median apophysis and the presence of an indentation on the distal conductor ( Figs 32–34 ). Females are similar to N. palinitropus in having an elongated atrium, but this being much shorter than in N. palinitropus . Description: Female holotype : Medium sized coelotine, total length 5.20. Dorsal shield of prosoma 2.60 long, 1.77 wide; opisthosoma 2.60 long, 1.69 wide ( Fig. 36 ). Eye arrangements of N. vietnamensis sp. nov. is similar to that of N. lingulatus sp. nov. AME smallest, approximately half the size of other eyes which are subequal and clustered (AME 0.08, ALE 0.16, PME 0.16, PLE 0.16); AME–PME separated by approximately PME diameter ( Fig. 35 ). Chelicerae with 3 promarginal and 2 retromarginal teeth. Legs normal length (I 7.28; II 6.06; III 5.54; IV 7.82) (1st leg/ dorsal shield of prosoma = 2.79). Spinnerets with ALS short; PMS small, approximately 11 aciniform gland spigots, 2 cylindrical gland spigots, minor ampullate gland spigots not observed on the specimen examined; PLS second segment long, with approximately 11–12 aciniform gland spigots, and 2 cylindrical gland spigots ( Figs 38–40 ). Epigynal teeth absent; atrium small, elongated, with a tongue-shaped posterior extension; copulatory ducts broad, covering most of spermathecae; spermathecae small, rounded, widely separated; spermathecal heads extended anteriorly, with distinct stalks ( Figs 30–31 ). FIGURES 42–43. Notiocoelotes vietnamensis sp. nov. , female paratype from Huong Son, Vietnam. 42 Tarsal organ (indicated by black arrow) and the third trichobothrium (indicated by white arrow, the hair itself is absent); 43 Trichobothrium, base, from the tarsus of the fourth leg. FIGURE 44. Records of species of Notiocoelotes gen. nov. Male paratype : Small sized coelotine, total length 3.20. Dorsal shield of prosoma 1.80 long, 1.75 wide; opisthosoma 1.40 long, 0.90 wide ( Fig. 37 ). Eye sizes and interdistances: AME smallest, approximately half the size of other eyes which are approximately same size and clustered (AME 0.04, ALE 0.10, PME 0.09, PLE 0.10); AME–PME separated by approximately PME diameter. Chelicerae with 3 promarginal and 2 retromarginal teeth. Legs normal length (I 5.84; II 4.80; III 4.70; IV 6.12) (1st leg/ dorsal shield of prosoma = 3.24). Palpus without patellar apophysis; RTA occupying most of tibial length; lateral tibial apophysis large, strongly bifurcated; cymbial furrow long, slightly more than half of cymbial length; conductor long, extending proximally, coiling, semi-circular; conductor dorsal apophysis absent; conductor lamella large; median apophysis large, simple, not spoon-shaped; embolus filiform, originating proximally ( Figs 32–34 ). Habitats. The spiders were collected by sifting leaf litter and by pitfall trapping in montane rain forest between 700–1100 meters elevation. Distribution. Vietnam (Huong Son) ( Fig. 44 ).
