Description. Male. Body (Fig. 4) reddish-brown, abdomen darker, maxillary palpi and tarsi lighter in color; body length 3.49–3.54 mm, combined width of elytra 1.30–1.33 mm.
Head about as long as wide, frontal margin anterior to eyes straight. Antenna (Fig. 92) with scape very long, three times as long as wide and three times as long as next antennomere, antennomeres from pedicel to antennomere VI about equal in length, VII elongate, longer than VI, VIII shorter than VII, but slightly longer than VI, IX–XI strongly modified, IX similar to that of P. walkeri, but with apex forming a spine, antennomere X as long as IX, similar to that of P. miraculum, but more curved medially, XI large, strongly pedunculate, with apical half distinctively enlarged. Maxillary palpus (Fig. 140) similar to that of P. walkeri, with basal part of segment II slightly expanded. Mandibles (Fig. 134) most similar to those of P. walkeri.
Pronotum as long as wide, coarsely punctured and densely pubescent, with anterior one-fourth of lateral sides angulate. Elytra (Fig. 15) most similar to those of P. walkeri. Hind wing (Fig. 87) much smaller and slenderer than in P. miraculum. Legs long and slender, protrochanter (Fig. 56) with a pin-like apical spine, profemur strongly thickened near middle, with a large apical spine, mesotrochanter (Fig. 57) elongate, with three minute protuberances, mesofemur without spines, hind legs not armed. Abdomen (Figs. 29, 30) with tergite IV transverse, more than twice as long as next, tergite VIII (Fig. 107) and sternite VIII (Fig. 106) similar to those of P. cornutus, but sternite VIII with basal half slightly more straight. Metaventrite (Figs. 78, 79) with two horn-like processes that are broadened and rounded at apices.
Aedeagus (Figs. 154, 155) most similar to that of P. miraculum, but with median lobe less expanded near apex; endophallus (Fig. 185) with three erect spines, left one shortest and median one longest, both well sclerotized at apex; all three spines curved right; parameres paired and almost symmetrical, with basal spine very elongate.
Female. Slightly smaller than male, similar in shape, basal metaventral process absent.
Remarks. This species is characterized by the pronotum with the lateral margins angulate at apical onefourth; antennal club uniquely modified and aedeagus with median lobe less expanded.
Distribution. China (Shanxi and Henan Provinces).
Etymology. We are happy to dedicate the specific name to Dr. Shûhei Nomura (Japan) for his continuous encouragement and guidance. The species name is a noun in the genitive case.
