NEW MATERIAL: 1 ♀; Indonesia, Sumatra, West Sumatra Province, old secondary forest above Harau Canyon, north of Payakumbuh , 750 m; 7.VI.2006; leg. P.J. Schwendinger (MHNG, sample Sum-06/11) .

REMARKS: Deeleman-Reinhold (2001: 419) provided a description and illustrations of the female paratype. The female of this species is recognized by the absence of anterior membranous bursae, by the thick-walled copulatory ducts, and by the specific shape of the spermathecae (Fig. 33). We present here another unique character found only in the female of this species: a digitiform appendage situated on the anterior surface of each spermatheca (Figs 28, 33-34).
