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) [vs 1.5 × (Fig. 26B)], copulatory ducts strongly curved to almost 60° angle (Fig. 21B) [vs 80° (Fig. 26B)] and secondary spermathecae larger than primary spermathecae (Fig. 21B) [vs as wide as primary spermathecae (Fig. 26B)].

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.
