D i s c u s s i o n: The macropterous morph of P. feuerborni was described from Sumatra by LUNDBLAD (1933) and redescribed by ANDERSEN (1983) from Java, Singapore, West Malaysia, and Thailand. The apterous morph was described by HECHER (2005). The Malaysian specimens differ from the descriptions by ANDERSEN (1983) and HECHER (2005), which were mainly based on specimens from Thailand, in some characters: (1) Row of long hairs on the first metatarsal segment of males usually with more hairs (5-7 vs. 4-5). (2) Apterous and macropterous females slightly larger. (3) Pronotum of macropterous specimens slightly wider. (4) Ratio of length/width of pronotum of apterous females larger (0.77 vs. 0.69-0.74). (5) Ratio of first and second metatarsomere of females smaller (0.68-0.69 vs. 0.73-0.82).

G e n e r a l d i s t r i b u t i o n: Thailand, West Malaysia, Singapore, Java ( ANDERSEN 1983). The record from the Philippines by ANDERSEN (1983) refers to an undescribed species ( SEHNAL 1999).
