Holotype (male). -
China: Fujian, Wuyishan, Kuatun [Guadun], elev. 2300 m, 27°40'N, 117°40'E, 4.ix.1938, leg. J. Klapperich - (Bonn, ZFMK).
Other specimens examined. -
Same locality as holotype, 31.vii.1938, leg. J. Klapperich, 1 female (paratype) (Bonn, ZFMK) .
Diagnosis. -
The male subgenital plate and paraproctal outgrowths of the new species are similar to those of Pteranabropsis infuscatus Wang et al., 2015; it differs by larger size, longer wings and longer ovipositor, by the metasternal plates that are roughly triangular without short conical tip instead of with conical tip in P. infuscatus . The female subgenital plate is similar in both species but in P. guadun sp. nov. has the narrow apical area for the greatest basal part rather wide and stout with parallel lateral margins and suddenly distinctly narrowed before tip instead of apical area regularly narrowed to tip.
Description. -
Medium to large sized species; habitus as genus. Prosternal lobes near base compressed, afterwards long spiniform, thin; mesosternal lobes in basal area wide, afterwards thin tubular with obtuse tip; metasternal lobes compressed triangular with faintly concave internal and convex external margins, towards tip swollen conical with obtuse tip; without narrow, roughly cylindrical area (Fig. 2P View Fig. 2 ).
Wings distinctly surpassing hind knees (Fig. 1H View Fig. 1 ). Fore wings 2.21-2.23 × longer than wide. Venation: radius with radius sector arising between middle and apical third of tegmen; media two-branched, branching between basal third and mid-length; cubitus anterior three-branched, branching before end of basal third and just before (male) or behind (female) mid-length; cubitus posterior free and undivided; with 5(-6) anal veins, the last one or two incomplete. Hind wings nearly semicircular, only slightly wider than long (about 1.3 ×).
Legs. Fore coxa with a strong spine at swollen anterior surface; mid coxa with a smaller spine at external margin. Fore femur with 4 (female) or 1 (male) small spines and mid femur with 3-4 (female) or 1 (male) spines at anterior-ventral margins, in the female only also with 0-1 spinules at posterior-ventral margin of mid femur. Hind femur with 2-5 external and 2-3 internal small spines on ventral margins; hind tibia with dorsal spines on inner margin slightly larger than on outer margin, ventral margins with few minute spinules; on both sides with 4 apical spurs, the dorsal two pairs very large, the following pair medium, the ventral-most pair small; internal spurs larger than corresponding external counterparts; ventral margin with 3 external and 1 internal spinules.
Male. Paraproctal outgrowths forming a long roughly cylindrical process with setose surface, slightly curved dorsad in subapical area, apex obtuse but with a small compressed pad at tip (Fig. 4J-K View Fig. 4 ). Subgenital plate in about little more than basal half with convex surface and approaching lateral margins; in somewhat less than apical half with faintly diverging lateral margins that, towards tip, form rounded lateral carinae that are slightly diverging posteriorly, at tip with insertion of stylus; otherwise apical area compressed with apical margin subtruncate and slightly oblique on both sides, interrupted by a V-shaped incision (Fig. 2G View Fig. 2 ). Phallus membranous, not well preserved in holotype (Fig. 7S-T View Fig. 7 ).
Female. Subgenital plate wide at base, triangularly narrowing posteriorly and terminating into a spiniform apical area that is distinctly longer than in P. carnarius , almost as long as the wide basal area and with sub-parallel lateral margins except for apical third with converging margins to acute tip (Fig. 5I View Fig. 5 ).
Coloration. -
General color medium brown, mixed with dark pattern; pronotum dark brown; legs marbled with light and darker flecks. Head: face light yellowish-brown with larger, indistinctly darker flecks and with smaller dark spots. Pronotum uniformly medium brown with light yellowish-brown rim. Tegmen light semi-transparent with dark brown spots; hind wings light semi-transparent with dark brown spots.
Measurements. -
(1 male, 1 female). In mm. Body w/wings: male 53, female 55; body w/o wings: male 29, female 30; pronotum: male 8.3, female 8.3; tegmen: male 41, female 42.5; hind femur: male 26, female 27; tegmen width: male 18.5, female 19; antenna: male 85, female 65; ovipositor: female 23.
Etymology. -
The name of the new species refers to the type locality; noun in apposition.
