Figs. 26 F–I

Material examined. Indonesia: Sumatera Selatan, Palembang , (2°59'S, 104°45'E), 1902, leg. Dr. A. Fuchs— 1 female (Museum Wiesbaden) .

Description. Medium sized species. Head: Face oval; forehead nearly smooth; fastigium verticis moderately wider than scapus; ocelli indistinct ( Fig. 26G ). Abdominal tergites two and three without stridulatory pegs.

Wings little surpassing hind knees ( Fig. 26F ). Tegmen: Radius and RS forked near tip. Media anterior fused at base with radius; media posterior absent; cubitus anterior simply dividing into two branches; cubitus posterior unibranched and free throughout; with 4 anal veins, last two with common stem.

Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with 9–10 external and 7–8 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine each; with 3 apical spurs on both sides.

Coloration. General color light brown; vertex unicolored; disc of pronotum medium-dark brown in middle, pale towards margins; hind margin rim dark brown. Legs of general color. Face in upper area to about ventral margin of eyes light brown including a pair of comma-shaped dark spots between bases of antennae, lower area including anterior area of genae, labrum and mandibles dark chocolate brown with few light spots below compound eyes, at clypeo-frontal suture and tip of labrum. Tegmen semi-transparent white, very faintly suffused with yellow along midline; veins and veinlets yellow; hind wing semi-transparent white with yellow veins and veinlets.

Male. Very similar to that of P. p. personata but projections of ninth abdominal tergite little stouter and inserted more in midline (for details see Gorochov 2004).

Female. Seventh abdominal sternite convexly covering base of subgenital plate. Subgenital plate about flat pear-shaped; in basal half auricular on both sides, thereafter with converging margins; apex shortly bilobate; surface little structured ( Fig. 26 H–I). Base of ovipositor normal. Ovipositor falcate, strongly curved with margins faintly approaching posteriorly and with longitudinal furrow that ends at beginning of apical area; before tip dorsal margin with a slight pre-apical expansion, tip subacute.

Measurements (1 female).—body w/wings: 28; body w/o wings: 15; pronotum: 5; tegmen: 20.5; tegmen width: 6.7; hind femur: 14; antenna: 120; ovipositor: 11 mm.

Nomenclatural details: Justified emendation; since the taxon was named after a German person, the incorrect original spelling "möschi" should be emended to "moeschi".
