Type locality. INDONESIA, Java, Soekaboemi [Sukabumi]

Distribution. Java, Malay Peninsula (Perak, SINGAPORE [new locality]), Sumatra

Remarks. Specimens from different parts of its distribution require further study to establish its species boundaries.Additionally, the male genitalia of the holotype from Java is not well-described and was not available for examination ( Gorochov, 2007 [2006]). Whether Gorochov’s specimens (2007[2006]) from Java, Perak and Sumatra are indeed Mistshenkoana bilineata is questionable. The genitalia of the specimen from Singapore compares well with specimens from Java (compared to from Perak and Sumatra) by its more elongated epiphallus, the shape of posterolateral epiphallic lobe and the shape of ectoparameres.
