Peltoperlopsis spec. Ph A

( Figs. 71-74 )

Material examined. Philippines: Palawan: Port Barton waterfall, 13 March 1995, A. Zwick, 1 ♀ (Zwick/Illies/LFS collection) .

Adult habitus. Biocellate. General color brown. Head dark brown except for pale area around compound eyes from posterolateral occipital margin forward to near antennal bases. Pronotum mostly dark but with paler area near anterolateral margin, along median suture and midlaterally ( Fig. 71 ). Wings and veins dark brown except bases of costa, subcosta and radius pale from wing base to first costal cross vein. Legs banded; femora pale basally, dark over apical half; tibiae dark brown but with pale base ( Fig. 74 ).

Male. Unknown.

Female. Forewing length 8.5 mm. Subgenital plate covers most of sternum 9; apex of plate strongly constricted to a narrow, ventrally directed, tongue shaped structure ( Figs. 72-73 ). Sternum 9 covers most of sternum 10 and is strongly keeled along meson, under subgenital plate.

Egg. Unknown.

Larva. Not definitely associated.

Diagnosis. The apically narrowed subgenital plate is similar to that of P. malickyi , but in that species the plate is not curved ventrad ( Stark & Sivec 1999) and the two species may not be closely related. Four larvae taken with this female and three others taken at two other nearby sites (Salakat Falls, road to Napsan, upper waterfall; Pasadenia, waterfall Nagkalit-kalit) could not definitely be associated with this female even though one pharate female larva was dissected. The larvae have Cryptoperla type gills and the larval thoracic sterna have a short intercalary setal row on the pro and metasterna and a pair of intercalary rows on the mesosternum; the anterior prosternal row and posterior metasternal rows are complete. If larvae of this type can be associated with this female, the generic placement is very questionable.
