( Figures 3 H, 16 A,B)

Diagnosis

Females of T. leptothecus sp. nov. can be recognized by the anteriorly narrowed, elliptic spermathecae and the simple curved ducts ( Figure 16 A,B).

Type material

Holotype. ♀, Malaysia: Johor State: Kota Tinggi Waterfalls, at the foot of Mt Muntahak , 170 m, rainforest along stream , 24–26 June 2001, leg. P.J. Schwendinger ( MHNG, SIM-01 / 07) .

Paratype. Data as holotype, 1♀, ( MHNG, SIM-01 / 07) .

Etymology

The specific epithet is a nominative form of an adjective (leptos = thin; thecus = sac), and refers to the shape of spermathecae.
