Joetjien (coll. RMNH ). Diagnosis . The new species is easily separable externally from its continental twin species, P. fola , by its somewhat shorter forewings with much darker brown ground colour, considerably narrower straight longitudinal stripe and paler hindwing. The genitalia show also striking differences between the two species. In the male genitalia, the new species has more evenly tapering uncus (that of P. fola is tapered more suddenly in its apical quarter); conspicuously narrower valva; short, broadly rounded lobe-like harpe covered distally with a row of robust spines (the harpe of P. fola is a largely elongate, apically pointed process covered densely with hair-like spinules); and much shorter and more pointed vinculum. The aedeagus of P. brunneostriata is much longer than that of its congener, being considerably thinner and more strongly curved. In the female genitalia, the new species has, as compared with those of P. fola , somewhat thicker apophyses, considerably longer eighth segment, V-shaped ostium bursae, longer ductus bursae and conspicuously larger needle-like signum bursae. Bionomics and Distribution . A poorly known species, only two specimens have been collected rather recently, the other examples of the type-series lack even the period of the year from the labels. These two specimens were found by Dr Diehl in the vicinity of his hospital in Dolok Merangir, at a low altitude forest area. All but one of the known specimens was found in Sumatra and Java, a single specimen has been collected in Singapore more than one hundred years ago.
