( Figs 29–32 View FIGURES 29 – 32 )
Diagnosis. This species is similar to P. orientalis (Hendel, 1914) from eastern to southern China in the characters of paramere and aedeagus, but can be distinguished from it by two characters of gonopods: the anterior processes sclerotized, with apical branch ( Fig. 31 View FIGURES 29 – 32 , a) slightly longer than submedian branch ( Fig. 31 View FIGURES 29 – 32 , b); the posterior processes nearly membranous, with spherical, distal part slightly broader then base ( Fig. 31 View FIGURES 29 – 32 , c). On the contrary, in P. orientalis : apical branch of sclerotized processes much longer than submedian branch; the base of membranous process distinctly thinned, stalk-shaped [see Fig. 2 View FIGURES 1 – 3 D in Okada 1977; cited as Amiota (Phortica) antheria ].
Description. Frons brownish yellow, with a few thin, sparse interfrontal setae. Pedicel and first flagellomere yellow. Face grayish brown. Clypeus white medially, dark brown laterally. Thorax yellow, with dark brown patches and pollinose pattern. Scutellum yellow, with brown patch medially. Legs yellow, with 3 brown rings on each tibia. All abdominal tergites yellow; second tergite with 1 small, brown patch on lateral margin and 1 triangular dark brown patch submedially each side; third and fourth tergite each with medially and laterally slightly protruded, sublaterally nearly interrupted, dark brown band on posterior margin; fifth and sixth tergites each with short, blackish band medially along posterior margin. Male terminalia: Epandrium pubescent anteroventrally, with ca. 13–14 setae on dorsal to posterolateral portion each side ( Fig. 29 View FIGURES 29 – 32 ). Surstylus lacking pubescence, with several setae and wedge-shaped prensisetae ( Fig. 29 View FIGURES 29 – 32 ). Additional (hypocercal) plate pubescent and connected to tenth sternite ( Fig. 30 View FIGURES 29 – 32 ). Hypandrial posterolateral lobe lacking pubescence ( Fig. 31 View FIGURES 29 – 32 ). Paramere pubescent submedially, flattened distally, with 2 sensilla and 3 teeth apically, and 1 triangular lobe-shaped process medially ( Fig. 32 View FIGURES 29 – 32 ). Aedeagus with 1 pair of slightly sclerotized bridges connecting it to the gonopod.
