Type material.

Holotype, female, 福建 崇安 1500m 芥桔子 1978.V.7 采集者:黄復生 [China: Fujian, Chong’an, 1500 m, 7.v.1978, Shuyong Wang, ex Fortunella margarita ] (NMNH). Paratypes, female, as holotype (IZAS, 1; NMNH, 1).

Diagnosis.

2.9 mm long (mean = 2.9 mm; n = 3); 2.23 × as long as wide. This species is distinguished by the mesonotal mycangial tuft the length of the scutellum; elytral disc flat; declivital interstriae punctate; declivital posterolateral margin carinate to interstriae 5; declivity moderately bisulcate; declivital margins ornamented by only two small sharp incurved spines at the base of interstriae 2 and 3; and declivital interstriae bearing fine erect hair-like setae.

Description

(female). 2.9 mm long (mean = 2.9 mm; n = 3); 2.23 × as long as wide. Body dark red-brown. Legs and antennae light brown. Head: epistoma entire, transverse, with a row of hair-like setae. Frons weakly convex to upper level of eyes, alutaceous, subshiny, punctate; punctures large, shallow, setose; punctures bearing a long, erect hair-like seta. Eyes shallowly emarginate just above antennal insertion, upper part smaller than lower part. Submentum large, distinctly triangular, slightly impressed. Antennal scape regularly thick, as long as club. Pedicel as wide as scape, shorter than funicle. Funicle 4-segmented, segment 1 as long as pedicel. Club longer than wide, obliquely truncate, type 1; segment 1 corneous, encircling anterior face; segment 2 narrow, concave, corneous on anterior face only; sutures absent on posterior face. Pronotum: 0.77 × as long as wide. In dorsal view rounded, type 1, sides convex, rounded anteriorly; anterior margin with a row of 6-8 serrations. In lateral view short and tall, type 3, disc shorter than anterior slope, summit at basal 2/5. Anterior slope with densely spaced, large coarse asperities, becoming lower and more strongly transverse towards summit. Disc subshiny with dense, fine punctures bearing moderate, semi-erect hair-like setae, some longer hair-like setae at margins. Lateral margins obliquely costate. Base transverse, posterior angles acutely rounded. Mycangial tuft present along basal margin, tuft moderately setose, approximately the width of scutellum. Elytra: 1.52 × as long as wide, 1.97 × as long as pronotum. Scutellum broad, large, linguiform, flush with elytra, flat, shiny. Elytral base transverse, edge oblique, humeral angles rounded, parallel-sided in basal 3/5, then narrowly rounded to apex; surface opalescent. Disc weakly convex, striae not impressed, with small, deep punctures separated by approximately one diameter of a puncture, setose, setae as long as two punctures, recumbent, hair-like; interstriae flat, punctate, punctures strongly confused, setose, setae 1-1.5 × width of interstriae 2, erect, hair-like, unarmed by granules. Declivity occupying approximately 1/2 elytra, steeply rounded, declivital face moderately bisulcate to interstriae 4; striae not impressed, strial punctures much larger and deeper than those of disc, and bearing setae as described for disc; interstriae minutely uniseriate punctate, setae 1-1.5 × width of interstriae 2, erect, hair-like, interstriae 2 as wide as interstriae 3 at midpoint of declivity, declivital margins ornamented by only two small sharp incurved spines at base of interstriae 2 and 3. Posterolateral margin carinate to interstriae 5. Legs: procoxae contiguous; prosternal coxal piece short, inconspicuous. Protibiae obliquely triangular, broadest at apical 1/3; posterior face smooth; apical 1/2 of outer margin with seven very large socketed denticles, their length much longer than basal width. Meso- and metatibiae flattened; outer margins evenly rounded with nine and ten large socketed denticles, respectively.
