Type material.
Holotype: ♀ (IZCAS-Ar44696), Laos, Bolikhamxay: Khamkeut Dist., 17.11 km west of Ban Laksao Town, Tham Mankone, Dragon Cave, 18.2216°N, 104.8127°E, ca 495 m, 27.XI.2012, Z. Yao leg.
Diagnosis.
The female of Typhlohnia banlaksao sp. nov. can be distinguished from T. sondoong sp. nov. by the length of copulatory ducts 4 × longer than diameter of primary spermathecae (Fig. 21B View Figure 21 ) [vs 1.5 × (Fig. 26B View Figure 26 )], copulatory ducts strongly curved to almost 60° angle (Fig. 21B View Figure 21 ) [vs 80° (Fig. 26B View Figure 26 )] and secondary spermathecae larger than primary spermathecae (Fig. 21B View Figure 21 ) [vs as wide as primary spermathecae (Fig. 26B View Figure 26 )].
Description.
Female (holotype; Figs 21A, B View Figure 21 , 28A View Figure 28 , 29A View Figure 29 ). Total body length 1.73. Carapace 0.74 long, 0.49 wide; opisthosoma 0.99 long, 0.77 wide. Eye sizes and interdistances: ALE 0.02, PME 0.01, PLE 0.03; PME-PME 0.05, PME-PLE 0.02, ALE-PLE 0.02. Clypeus 0.09 high. Chelicerae with three promarginal and two retromarginal teeth. Leg measurements: I 3.03 (0.84, 0.26, 0.71, 0.67, 0.55); II 2.80 (0.79, 0.26, 0.62, 0.64, 0.49); III 2.58 (0.70, 0.22, 0.57, 0.62, 0.47); IV 3.09 (0.91, 0.26, 0.81, 0.84, 0.57). Leg spination: femur I p1; patellae I-IV d1; tibiae I-II p1 d2, III-IV r1 d1.
Coloration (Figs 28A View Figure 28 , 29A View Figure 29 ). Carapace pale yellow, with a few long brown hairs. Fovea longitudinal, reddish-brown. Six eyes, white. Chelicerae, labium, and gnathocoxae pale yellow, with long brown hairs; sternum yellowish. Legs white with some spines. Opisthosoma oval, grey. Spinnerets white.
Epigyne (Fig. 21A, B View Figure 21 ). Epigynal plate 1.55 × wider than long. Depression obvious, ends with copulatory openings. Copulatory ducts long, almost 4 × longer than width of primary spermathecae, strongly curved to almost 60° angle, base bifurcate. The short one connected to secondary spermathecae, the other connected to primary spermathecae. Secondary spermathecae oval, 1.5 × wider than primary spermathecae. Fertilization ducts directed at 11:00 o’clock position from spermathecae.
