Two new species of the genus Uloma Dejean, 1821, Uloma fengyangensis sp. n. and Uloma acrodonta sp. n., are described and figured from Zhejiang Province of China. Uloma bonzica Marseul, 1876 is recorded from China for the first time. A key to the known Uloma species from Zhejiang of China and a list of Uloma species from China are provided.

The tenebrionid genus Uloma was established by
Two new species of Uloma, Uloma fengyangensis sp. n. and Uloma acrodonta sp. n., were collected from Mt. Fengyangshan in Zhejiang Province of China. Uloma bonzica Marseul, 1876, a species newly recorded from China, was also sampled at the same locality. The two new species are described and figured in this paper, and a dorsal habitus of the new record is also presented. In order to help with the identification of the Uloma species from Zhejiang, a key to its species known from Zhejiang Province is provided.
The terminology of morphological structures follows that of
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).
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.
Male (Fig.
Pronotum (Fig.
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.
Abdominal ventrites finely densely punctate, punctuation larger and subcontiguous towards lateral portions.
Aedeagus (Fig.
Female. Unknown.
Body length: 11.0 mm; elytral width at widest point: 4.5 mm.
The species epithet refers to the Mt. Fengyangshan where the species was collected.
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 U. 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 U. 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 U. reticulata); (4) male metatarsomere 1 significantly longer than 4 in the new species (1 almost as long as 4 in U. 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 U. reticulata).

Holotype, ♂, labelled “19 July 2012; China, Zhejiang, Longquan County, Mt. Fengyangshan; X. Wang and J. Jiao lgt.; the Museum of Hebei University” (white, rectangular, printed, in Chinese). Paratypes, 1♂1♀, labelled as holotype. All types have additional label “Holotype (and Paratype, respectively), Uloma acrodonta sp. n. Liu & Ren det. 2015” [red (and Paratype with yellow, respectively), rectangular, printed and handwritten], and all of them are deposited in MHBU.
The new species is characterized by the following: clypeus slightly elevated with two small ridges; antennomeres 5 and 7 obviously sharply protruding at inner border; pronotum with a small and shallow anterior impression; protibia broader, with 8–9 sharp large denticulations at apical 2/3 of outer edge; last ventrite with a shallow impression.

The species epithet refers to the sharply protruding at inner border of antennomere 5 and 7.
The new species is most similar to Uloma quadratithoraca Liu & Ren, 2008, but can be distinguished from the latter by the following characters: (1) male clypeus slightly elevated with two small ridges in the new species (without ridge in U. quadratithoraca); (2) male antennae long, reaching to the middle of pronotum, antennomeres 5 and 7 obviously sharply protruding at inner border in the new species (5 and 7 not protruding in U. quadratithoraca); (3) male pronotum with a small and shallow anterior impression in the new species (without anterior impression in U. quadratithoraca); (4) male protibia distinctly broader, with 8–9 sharp large denticulations at apical 2/3 of outer edge in the new species (narrower, with 8–9 undulant denticulations at apical 1/2 in U. quadratithoraca); (5) male last ventrite with a shallow impression in the new species (without impression in U. quadratithoraca).
Moreover, five additional species (U. intriconicula Liu, Ren & Wang, 2007, U. metogana Ren & Yin, 2004, U. takagii Masumoto & Nishikawa, 1986, U. rubripes rubripes (Hope, 1831) and U. rubripes minor Gebien, 1914) are known to occur in China and its surrounding areas with antennomere 5 and 7 obviously sharply protruding at inner border. The new species is easily distinguished from them based on shape differences in the male pronotum, pronotal anterior impression, protibia, metatibia, ridges of clypeus, and whether or not the pronotal anterior impression exists in female.
