ON A NEWLY RECORDED GENUS AND TWO NEW SPECIES OF EUMOLPIDAE (COLEOPTERA) FROM FUJIAN PROVINCE,CHINA

本文记述福建省肖叶甲科二新种,其中一种属于国内新纪录属。新种模式标本保存于中国科学院动物研究所。粗角叶甲属 Clisitherella Chen, 1940 本属在国内系新纪录。本属过去仅知一种——Clisitherella suturalis Chen, 1940(模式产地:越南北部)。体长卵形。唇基前缘呈圆形凹切,两侧突出成尖齿状。雄触角粗大,第三、四两节宽而略扁,背面各有一浅圆凹洼,末端三节细狭。复眼完整,内缘稍弧弯。下颚须末节细。

In this paper two species of Eumolpid-beetles, of which one species belongs to a newly recorded genus (Clisitherella Chen) from China, are described as new. A11 the type specimens are kept in the Institute of Zoology, Academia sinica. Clisitherella fukienensis, sp. nov. (fig. 1) Elongate-oval, reddish-brown; elytra yellowish-brown, with lateral margins and suture black. Legs with apex of femora as well as tibiae and tarsi black. Antennae black, except three basal segments brownish. Head moderately densely and rather strongly punctate, epistome bounded an- teriorly on each side with a distinct ridge, anterior margin of clypeus roundly emarginate and produced on each side into a strong tooth. Antennae robust, in male about 3/4 the length of the body, the 1st segment very thick and cylindri- cal, slightly curved on the inner side; 2nd short, moniliform; 3rd and 4th broad and flat, each with an oblong fovea on upper surface; 5-7th thick, a little longer and narrower than the 4th; the last three segments slender; segments 4-10th dne- sely fringed with pale long hairs on underside; Antennae of female slender, ab- out half as long as the body. Pronotum about two times as broad as long, later- al margins explanate and rounded; disc with punctures rather scattered, distinct- ly larger anteriorly than posteriorly, being smaller and weaker than those of the head. Elytra with lateral margins explanate, coarsely and irregularly punctate. Anterior margin of pro-episternum straight. Prosternum oblong. Femora strong and thick, unarmed, external apical angle of tibiae strongly developed and curved in male, less developed in female; claws appendiculate. Body length 5.2-5.8mm; breadth 3.1mm. Holotype ♂:Xi-qin, Nanping County, Fujian Province, 25.iv.1981, collected by the Department of Forestry, Fujian Province. Allotype ♀: ditto. Distinguish- ed from C. suturalis Chen by the color of the legs being bicolorous instead of unicolorous, the basal three instead of six segments of antennae pale colored; the antennae of male fringed with long hairs, while in the latter species without long hairs. Hyperaxis phoebicola, sp. nov. (fig. 2) Narrowly oblong; dull black, entirely covered with greyish-white or grayish- yellow scales, intermixed with short, rigid and erect hairs on elytra, and with long soft white hairs on underside of thorax. Legs reddish piceous or reddish bro- wn; antennae brown, darker on intermediate segments. Head coarsely and rugo- sely punctate, with a longitudinal depressed line in the middle, frons triangularly depressed in the middle; clypeus convex, anterior margin slightly concave. Ant- ennae long and slender, exceeding half of the length of the body. Prothorax cylin- drical, slightly broader than long, sides parallel, obsoletely margined on basal half; disc rugged, punctures smaller and denser than those of the head, transver- sely rugose. Scutellum long, apex rounded. Elytra much broader than thorax at base, surface much more coarsely punctate than the head and pronotum, punct- ures arranged in close irregular rows and separated by 4 or 5 not very distinct Vittae. Anterior margin of pro-episternum straight. Femora each with a small tooth beneath, the anterior and posterior femora a 1ittle longer and thicker than the middle ones; tibiae not emarginate at apex; claws bifid. Body length 6-7mm; breadth 2.8—3.2mm. Holotype ♀: Xin-kou, Sanming Municipality, Fujian Province, 20.vi.1982, by Lin Ji-xing. Paratype ♀: ditto. Host: Phoebe Nees. Distinguished from all its congeners by the large, narrow and parallel-sided body, and the rugged surface of pronotum.
