Type material.

Holotype, ♂ (MHBU), labelled "25 July 2007; China, Zhejiang, Longquan County, Mt. Fengyangshan; H. Y. Liu and Z. H. Gao lgt.; the Museum of Hebei University" (white, rectangular, printed, in Chinese); "Holotype; Uloma fengyangensis sp. n. Liu & Ren det. 2015" (red, rectangular, printed and handwritten).

Diagnosis.

The new species is characterized by the following: mentum broadly cordate, with several short medial hairs and a pair of semi-circular hairy patches on near lateral margins; antennomere 5-10 sublinearly truncate, with one long groove on each inner side; pronotum with a pair of low protuberances on lateral margins and posterior margin of anterior impression respectively; metatarsomere 1 significantly longer than 4; apicale of aedeagus with a shallow depression on centre at basel 1/3, parallel–sided at apical 2/3 in dorsal view.

Description.

Male (Fig. 1A). Head transverse, with small punctures in apical half, and with sparse large punctures in basal half. Labrum trapezoidal, sparsely punctate, scattered with long and yellow hairs. Clypeus densely and distinctly punctate, anterior margin weakly emarginate, slightly elevated with two small ridges. Frontoclypeal suture deeply impressed. Genae slightly convex and extended, temples reduced. Eyes transverse, with at least 3-4 facets at narrowest point in lateral view; distance between eyes approximately 2.7 times longer than their diameter. Frons weakly convex but depressed on centre, with large punctures. Mentum (Fig. 2C) broad cordate, weakly emarginate at anterior margin, slightly concave with several short medial hairs, with a pair of semi-circular hairy patches on external sides. Ligula (Fig. 2C) deeply emarginate anteriorly, depressed in the middle with sparse long hairs. Terminal maxillary palpomere somewhat knife-shaped. Antennae (Fig. 2A) long, reaching to the middle of pronotum; antennomere 1 thick, 2 very short, 3 long and narrow, 4 short, 5 - 10 gradually widening, forming a more or less distinct club, 8-10 extremely transverse, nearly rectangular, 11 transverse-oval; 5-10 sublinearly truncate with one long groove at each innerside (Fig. 2B); ratio of the length (and the width) of antennomeres 2-11 as follows (mm): 8 (10): 9 (10): 7 (12): 7.5 (15): 7.5 (16): 8 (18): 8 (20): 9 (22): 9 (21): 12 (19).

Pronotum (Fig. 2D) transverse, nearly 1.5 times as wide as long, widest at middle, with small punctures widely spaced on centre and becoming denser toward sides, with reticulate microsculptures. Pronotum with a small and deep anterior impression and a pair of low protuberances on both sides and posterior margin of impression respectively, and with a shallow groove in the middle of posterior margin. Anterior margin emarginate with narrow border only at both apices, without border in the middle 1/3, and with dense short hair fringes. Lateral margins arcuate, strongly narrowing forward and less so from widest point to base, with narrow border. Basal margin slightly convex, with a pair of oblique shallow impressions. Anterior angles subrectangular, posterior angles obtuse. Prosternum with dense large and partly confluent punctures, posternal process (Fig. 2E) rounded in lateral view, smoothly descended at apex, with sparse small punctures centrally. Propleuron with long wrinkles and large confluent punctures.

Scutellum subtriangular, with very sparse small punctures. Elytra nearly parallel–sided; elytra distinctly punctato–striate, punctures of elytral rows small and only somewhat broader than stripes; intervals slightly convex, distinctly and sparsely punctate with several transverse wrinkles, lateral margins visible only at humeri in dorsal view. Hind wings developed.

Protibia (Fig. 2F) with two equal apical spurs; slightly concave, narrow at base, then strongly and gradually explanate on both inner and outer edges; inner edge weakly emarginate at base, slightly protruding to inner apex, fringed with yellow short hairs becoming denser and longer toward apex; outer edge with 8-9 sharp denticulations at apical 3/4 scattered with short hairs; dorsal surface with a long depression near apex and large sparse and confluent punctures; ventral surface with a row of several small sharp protuberances and short sparse hairs. Mesotibia feebly and gradually expanding toward apex, outer edge with small denticles and sparse long hairs. Metatibia feebly and gradually expanding toward apex, outer edge with sparse long hairs. Length ratios of metatarsomeres (Fig. 2G) 1 to 4 as follows: 35: 9: 9: 28.

Abdominal ventrites finely densely punctate, punctuation larger and subcontiguous towards lateral portions.

Aedeagus (Fig. 2 H–I) with basale subparallel–sided; apicale slender, gradually narrowing with a shallow depression on centre at basel 1/3, parallel–sided at apical 2/3, truncate at apex in dorsal view, with a longitudinal depression on centre in ventral view, slightly curved in lateral view.

Female. Unknown.

Body length: 11.0 mm; elytral width at widest point: 4.5 mm.

Etymology.

The species epithet refers to the Mt. Fengyangshan where the species was collected.

Remarks.

The new species is similar to Uloma reticulata Liu, Ren & Wang, 2007, but can be distinguished from the latter by the following characters: (1) male mentum broadly cordate, slightly concave with several short medial hairs, with a pair of semi-circular hairy patches on near lateral margins in the new species (subhexagonal, with cordate convex in middle, without hairy patch in Uloma reticulata ); (2) male antennomere 5-10 sublinearly truncate, with one long groove on each inner side in the new species (5-9 sublinearly truncate with one long groove in Uloma reticulata ); (3) male pronotum with a pair of low protuberances on lateral margins and posterior margin of anterior impression respectively, anterior angles subrectangular in the new species (anterior impression of pronotum without protuberance in Uloma reticulata ); (4) male metatarsomere 1 significantly longer than 4 in the new species (1 almost as long as 4 in Uloma reticulata ); (5) apicale of aedeagus gradually narrowing with a shallow depression on centre at basel 1/3, parallel–sided at apical 2/3 in dorsal view in the new species (gradually narrowing from base to apex, then slightly widening nearly apex in Uloma reticulata ).
