Introduction

This species has been recorded more widely than its congenor but this might simply mean it is more common rather than more widespread. An examination of specimens in collections will establish its distribution with greater accuracy. P. stalii is generally smaller than P. reticulata but otherwise is quite similar in appearance.

Diagnosis

Pallide subolivaceo-flavescens, subtus cum pedibus obscurior, interdum fusco-ferrugineus, limbo costali tegminum ad basin cuneatim fusco-maculato, dorso abdominis fere toto et mesostethio nigris, his valde nitidis, tegminibus late flavescente-limbatis, in disco decoloribus, subvitreis, hyalinis, alis vitreo-hyalinis. ♂: long. corp. 3,5 mill., long. corp. c. tegm. 6 mill., lat. 2 mill., ♀: long. corp. 5 mill., long. corp. c. tegm. 7 mill., lat. 2.75 mill. Haec species, praecedenti quoad structuram et formam simillima et valde affinis, magnitudine, venis tegminum, pronoto antice magis angulatim producto, fronte ad latera costis obliquis, transversis instructa facile differt (Spångberg 1878).

Female. Greenish yellow, rarely yellowish brown. Postclypeus brown, with about 10 transverse impressed brownish black lines at each side (incl. 2 on tylus), the upper ones narrower and paler. Pronotal punctures, especially those at anterior 1/2, slightly darker than ground color. Venter of mesothorax largely brown. Fore tibia and femur brown, tarsus and extreme apex of tibia black. Mid leg black, knee brown. Hind leg brown, darker toward apex, tibial and tarsal spines apically shining black. Postclypeus finely and rather densely punctate; rugae at intervals of impressed lines rather prominent and about as broad as latter; lower area with fine feeble transverse striae; discal area with few short fine longitudinal striae. Pleurostome and lorum densely, minutely punctate; relative breadths of pleurostome and lorum and length of gena proper 5.75 : 3.5 : 4. Crown coarsely, shallowly, irregularly wrinkled; tylus slightly flattened, distinctly more elevated than side piece of vertex; the latter weakly concave; tentorial pit large roundish, scarcely depressed; ocellar area depressed, anteriorly a little more elevated than tylus; occipital margin strongly reflexed throughout; supra-antennal triangle depressed, about 2/3 as long as broad. Pronotum strongly convex, coarsely and deeply reticulate-punctate, with meshes approximately as long as broad; calli shallow. Scutellum coarsely rugose, often with distinct punctures intermixed; apical 1/5 feebly foveate. Tegmen coarsely reticulate-punctate throughout; venation variable in details, R branched beyond middle of costal margin, very rarely at middle; R1 usually divergent from costal margin near apex; ir 2-4 in number, all far from base of preapical cell 1; rm1 short or replaced by adnation of Rs and M near middle; preapical cell 3 basally often with 1-2 supernumerary oblique stubs or crossveins; basicostal triangle weakly depressed; preapical and apical cells in teneral specimens distinctly concave, in fully matured ones almost plane; corial appendix as large as or slighly smaller than claval appendix. Relative lengths and breadths of head, pronotum and scutellum 10 : 27.5 : 30 and 39 : 40 : 17 respectively. Tegmen 4.7-5.8 mm long.
Male. Duller than female, clavus and apical corial margin of tegmen tinted with yellowish brown to dark brown. Postclypeus with short weak keel near top. Scutellum more coarsely and deeply sculptured. Tegmen 3.4-4.3 mm long. (Maa 1963)
