Sesieutes schwendingeri Deeleman-Reinhold, 2001: 461, figs 771–774, description of ♂ ♀.

Type material

Holotype: ♂, Thailand, Chiang Mai Province, Chiang Dao District, Doi Chiang Dao Wildlife Sanctuary, 510 m, pitfall trap, 22 September–25 October 1990, P.J. Schwendinger leg. (MHNG, examined, Figures 1A, 4A–C, 9A–C).

Paratype: From type locality, 450 m, 7 March 1987, P.J. Schwendinger leg., 1♀ (MHNG, examined, Figures 2A, 7A, 8F).

Diagnosis

Males of J. schwendingeri comb. nov. can be recognised by the large and curved conductor that is divided into a heavily sclerotised outer margin and a semi-transparent inner membrane (Figures 4A, 9A–C); the apex of conductor is gradually tapered and abruptly bent anteriorly (Figures 4C, 9B). Females can be distinguished by the large copulatory orifices that are situated at the centre of the epigynal region (Figure 7A), and by the middle portion of the internal ducts, which are greatly enlarged, whereas the anterior part of the spermathecae is spherical (Figure 8F).

Distribution

Known only from the type locality in northern Thailand. Other specimens from different localities previously known (Deeleman-Reinhold 2001: 461) were misplaced (see J. lunulata sp. nov. for more details).
