Parayuanamia producta Xing & Li, in Li, Dai & Xing, 2011: 171.
Length. Male: 4.6–5.1mm.
Description. Ground color stramineous marked with orange and brown; dorsum with pair of orange longitudinal submedial bands extended from crown apex to scutellum. Fore margin of head white bordered with dark brown, crown apex with pair of thin brown bands between midline and eyes, coronal suture dark brown (Fig. 5 A); face mostly brown, with paired white arcs (Fig. 5 C). Pronotum with two pairs of longitudinal bands laterad of submedial bands, midline of pronotum and scutellum brown (Fig. 5 A). Forewing brown, becoming paler toward costal margin, veins contrastingly pale; legs light brown with few darker transverse bands on femora (Figs. 5 A–B).
Head wider than pronotum, crown depressed, anterior margin parabolically rounded in dorsal view, distinctly shorter than minimum distance between eyes; ocellus closely adjacent to and nearly touching eye; antenna longer than head width (Figs. 5 A–B); anteclypeus parallel-sided, not extended to ventral margin of face; lorum semicircular, slightly narrower than anteclypeus, well separated from lateral margin of face (Fig. 5 C). Forewing with anterior branches of vein R not strongly reflexed; with four apical and three anteapical cells, apical cells shorter than half length of anteapical cells, inner anteapical cell very long; claval veins connected to each other by 0–2 crossveins, vein Pcu connected to claval suture by crossvein; appendix present but narrow (Figs. 5 A–B). Front femur with AM1 seta large, stout, situated at mid-height of apex, intercalary row with ~8–10 fine pale setae, row AV with ~16 short, stout, slightly curved setae in basal half; tibia rows AD and PD each with 4 macrosetae. Hind femur macrosetal formula 2+2+1, tibia rows PD, AD and AV with 8, 10 and 13 macrosetae, respectively; AD and PD with 0–5 and 1–4 shorter setae between successive macrosetae; PD with intercalary setae longer than those in AD; row PV with ~22 fine, close-set setae; tarsomere I with 2 ventral longitudinal rows well differentiated, pecten with 3–4 platellae.
Male genitalia. Pygofer lobes fused dorsomedially for considerable distance near base, forming long, unbroken tergite (Fig. 6 B); lobes without processes, with numerous macrosetae in distal half (Figs. 6 A–B). Valve and subgenital plates articulated (Fig. 6 C). Subgenital plates separate throughout length but with medial margins closely appressed, lateral margin nearly straight, with uniseriate row of marginal macrosetae (Fig. 6 C). Style with very long articulatory arm, preapical lobe short, angular, apex simple, tapered, without process (Fig. 6 D). Connective elongate, slender, arms each with lateral lobe near anterior end (Figs. 6 E–F). Aedeagal shaft extremely elongate and slender,>3 times longer than connective, slightly curved dorsad, distal processes very slightly divergent in dorsal view, gonopore apical on dorsal surface (Figs. 6 E–F).
Remarks. This species is similar to the type species of the genus, Y. anastoma Zhang & Duan, in overall structure, color pattern and male genitalia but differs in having a shorter, broader crown, male subgenital plates separate throughout their length and the aedeagus much more elongate, with the shaft more than three times longer than the connective (less than two times longer in Y. anastoma Zhang & Duan).
