( Figs 2–6View FIGURES 2 – 6)

Diagnosis. This new species belongs to the bellottii species group ( Chant & McMurtry, 2004), characterised by having seta z 4 shorter than 2 / 3 the distance between its base and the base of s 4. Within this group, it belongs to the msabahaensis  species subgroup, by having a spermatheca with calyx elongate, with sides approximately parallel.

The new species is similar to Transeius msabahaensis Moraes et al., 1989  and Transeius rufus  Denmark & Evans, 1999. It differs from T. msabahaensis  by having Z 4, Z 5 and s 4 shorter (ratio: 0.41; 0.63; 0.26, respectively); s 4 serrate; all macrosetae on leg IV Sg IV and Sti IV longer (ratio: 0.27; 0.13, respectively); calyx of spermatheca shorter (ratio: 0.53) and movable cheliceral digit with seven teeth.

The new species differs from T. rufus  by having Z 4, Z 5 and s 4 shorter (ratio: 0.46; 0.64; 0.3, respectively); s 4 serrate; all macrosetae on leg IV Sg IV and Sti IV longer (ratio: 0.24; 0.76, respectively) and movable cheliceral digit with seven teeth.

Adult female. Five females examined. Idiosomal setal pattern 10 A: 9 B / JV- 3 / ZV ( Chant & Yoshida-Shaul, 1992).
