Remarks. The new records are from sites in the central and southern regions of Vietnam, generally north of the Lam Dong site where a paratype was collected ( Zwick 1986). The females are associated on the basis of occurrence together with males of P. vietnamensis at two sites and on the basis of slightly larger size for this species than for others found at Cat Tien National Park.

Female. Forewing length 10-11 mm. Body pale, without distinctive dark pigment except on margins and median suture of pronotum. Subgenital plate lobes directed inward and apically narrowed; notch U-shaped ( Fig. 36 View Fig ). Plate generally similar to that of P. maindroni (Navas) and Phanoperla sp. D ( Zwick 1982) but the notch appears to be somewhat narrower and more rounded anteriorly than for either of these species.

Egg. Length ca. 435 µm, equatorial width ca. 205 µm. Collar short and ca. 84 µm wide at rim; basal constriction ca. 74 µm wide diameter ( Fig. 33 View Figs ). Chorion punctate over most of surface but smooth in a narrow equatorial ring ( Fig. 35 View Figs ); chorionic pits absent in zone along ribs extending from collar ( Fig. 34 View Figs ); pits deeper and more distinct on lid ( Fig. 35 View Figs ). Micropyles appearing evenly spaced in specimens examined; orifices surrounded by smooth circular rims. The egg of P. vietnamensis is similar to that of P. wedda ( Zwick 1982) but varies in lacking pits along the chorionic ribs associated with the collar.
