GENUS EROTIS MEYRICK (LEPIDOPTERA: OECOPHORIDAE) NEW FOR CHINA

Abstract  This paper reports the genus Erotis Meyrick for the first time from China. Two new species Erotis expansa sp. nov. and Erotis punctalosa sp. nov. are described. E. expansa sp. nov. is related to E. phosphora Meyrick both in appearance and in the male genitalia, but can be differentiated from the latter by uncus broader and slightly concave at middle of caudal margin, gnathos nearly as long as uncus and valva with costa almost straight in the male genitalia. E. punctalosa resembles E. expansa sp. nov. externally, but can be easily distinguished from the latter by the female genitalia: eighth tergite caudally almost straight; two signa large thorn-like, basal plate irregularly triangular in shape, with fine spines along anterior margin. The photographs of the adults and the genital structures of the new species are provided. A key to all the known species of Erotis is given.

水蜡蛾一新属一新种：（鳞翅目：水蜡蛾科）

Brahmaea属是Walker(1855)以Bombyx certhia Fabricius为模式种成立的。Mell(1929)根据成虫形态特征、后翅翅脉的差异(有无连接Sc+R_1和Rs脉的横脉),将亚洲的水蜡蛾分为二群,建立一个新亚属 Brahmophthalma Mell并绘有Brahmaea Walker属与新亚属内每个种的翅脉简图以示区别;Bryk(1949)将Brahmophthalma提升为属。我们在整理和研究水蜡蛾的标本中,发现Brahmaea Walker属中实际存在着成虫形态和外生殖器差别很大的两个类群,作者认为有必要将其分为两个属,建立一个新属,并记述一新种。     

Poorly known stonefly species, <Emphasis Type="Italic">Isoperla pseudornata</Emphasis> and <Emphasis Type="Italic">Kaszabia nigricauda</Emphasis> (Plecoptera,Perlodidae), from the Eastern Palaearctic

The previously unknown male of Isoperla pseudornata Zhiltzova and nymph of Kaszabia nigricauda (Navás) of the family Perlodidae are described. Sternite VIII of the male of I. pseudornata has no vesicle, the posterior margin is covered medially with strong short brownish setae. Sternite IX forms a subgenital plate. The everted aedeagus is upcurved, turned towards the dorsum, with two rounded lobes and one finger-shaped apical lobe terminating with a membranous funnel depressed medially. The aedeagus membrane is covered with small fine pointed sclerotized spinules; spinules absent on the tip of the funnel. The funnel basally and the finger-shaped apical lobe ventrally are covered with fine pointed sclerotized spinules and rounded sclerotized formations. I. pseudornata differs from the other Eastern Palaearctic congeners in the shape of spots on the head, pronotum, and abdominal tergites. The head of K. nigricauda nymph bears a large brown M-shaped spot forming along the anterior margin two fine stripes widened on the frontoclypeus; the interocular area bears a small pale spot merged with the large transverse W-shaped spot on the occiput. The lacinia is narrowed to the apex, bidentate; the tip of the galea reaches the base of the subapical tooth. The pronotum bears a pale cruciform medial spot, the lateral fields are dark, the lateral margins are pale. The meso-and metanotum exhibit a pale complicated pattern widened to the base of the wing pads. The legs are pale. The abdominal tergites are brown, with a pale transverse stripe widened laterally on the last tergites. Tergite X bears a large pale heart-shaped spot medially. The cerci bear a silky hair fringe dorsally; in the apical part, the apical whorl of cerci has short setae; one ventral and one dorsal seta are longer than the others; the dorsal setae are longer than ventral ones.

A new species, Chenia zanderi C.Feng & J.Kou, from Xishan Forest Park in Yunnan Province, China is described and illustrated. Particularly distinctive features of the new species are the fragile stems and leaves fragile along their insertions, narrow leaves usually constricted near the middle, broadly rounded leaf apices with a long apiculus, large distal laminal cells with numerous solid and bifurcate papillae, a narrow groove on the distal ventral surface of the costa, and absence of a costal stereid band. A key for the species recognised in Chenia R.H.Zander is also provided.     

A new genus and species of darkling beetles of the tribe Helopini (Coleoptera,Tenebrionidae) from Turkey

A new genus and species Microdocnemis xerophilicus gen. et sp. n. of the tenebrionid-beetle tribe Helopini is described from southwestern Turkey. The new genus belongs to the cylindrinotoid group of genera and is closely related to the genus Odocnemis Allard, 1876 in the structure of the male genitalia and female genital tubes and in the denticulation of the inner margin of the fore tibia. Microdocnemis differs from Odocnemis in the following characters: body very weakly flattened dorsally and ventrally; apical part of elytra, body ventrally, and epipleura with hairs; anal sternite with double bordering; apical margins of tibiae with short thick spines. The only species of the new genus inhabits xerophytic stony biotopes and has been found under stones; the species of the genus Odocnemis live on tree trunks covered with lichens.     

Dyrithiopsis lakefuxianensis gen. et sp. nov. from Fuxian Lake, Yunnan, China, and notes on the taxonomic confusion surrounding Dyrithium

A new taxon with Dyrithium-like characteristics was collected from Lake Fuxian in China. The taxon is typical of the Amphisphaeriaceae in that it has relatively large, ostiolate, immersed ascomata, unitunicate asci with a J+ subapical ring, and brown ascospores. It is similar to Dyrithium in that it has muriform ascospores, but considerable confusion surrounds this genus. In Dyrithium asci are bitunicate and lack a J+ subapical ring, while this was not true of our species. A new genus, Dyrithiopsis, therefore is established to accommodate this new taxon. Details of its anamorph also are provided, based on cultural studies. Parsimony analyses of part of the large-subunit rDNA provide further evidence to support the familial placement of this new genus in the Amphisphaeriaceae. The taxonomic position of Dyrithium also is discussed.     

Two new species of Panorpa (Mecoptera,Panorpidae) from the Hengduan Mountains in Yunnan,China

Two new species of the genus Panorpa Linnaeus, 1758 are described from the Hengduan Mountains in Yunnan, China. Panorpa diqingensis sp. n. can be distinguished from its congeners by vertex dark brown, and occiput yellow; pleura dark brown; gonocoxites bearing a cluster of stout black setae on inner apex; parameres S-shaped in male genitalia. Panorpa dispergens sp. n. can be readily differentiated from other Panorpa species by apical band with a hyaline spot in wings; gonocoxites with a cluster of stout dark brown setae and 3–5 long setae on inner apex; female medigynium with a pair of basal plates. The number of Panorpa species in Yunnan is raised to six. A key to Yunnan species of Panorpa is presented.     

TWO NEW SPECIES OF SUBGENUS CALCEORHOPALUM TSUNEKI FROM CHINA (HYMENOPTERA: SPHECIDAE)

Abstract  Two new species of the subgenus Calceorhopalum Tsuneki of the genus Rhopalum Stephens are described. The new species, Rhopalum ( Calceorhopalum) odontodorsale sp. nov. from Sichuan and Guizhou Province, is similar to R . (C.) spinicollum Tsuneki, but can be distinguished from the latter in the shape of clypeus, vertex with denser and larger punctures, anterior lateral corner of collar with a small tooth, tarsomere I of fore legs rather broad in male, and the shape of male genitalia. Holotype (♂) is deposited in the Insect Collections of Institute of Zoology, Chinese Academy of Sciences. Paratypes (9 ♂♂ 14 2 2 ) are deposited in the Insect Collections of Institute Zoology, Chinese Academy of Sciences and the Insect Collections of Zhejiang Agricultural University separately. The other new species, Rhopalum ( Calceorhopalum) rubigabdominale sp. nov. from Sichuan Province, is similar to R (C.) spinicollum Tsuneki also, but can be distinguished from the latter by the characters of the vertex concave, anterior lateral comer of collar rounded, posterior lateral corner of propleuron with a coarse and long tooth, prepectus with blunt comer medially, head and thorax with denser and larger punctures, abdomen yellowish or reddish brown, and the shape of male genitalia. Holotype (♂) and paratypes (3♀♀) are kept in the Insect Collections of Institute Zoology, Chinese Academy of Sciences.

New species and new stage descriptions of Campsurus major species group (Polymitarcyidae: Campsurinae), with first report of silk-case construction in mayfly nymphs

Campsurus major, C. argentinus and C. amapaensis sp. nov. form a monophyletic group supported by the following apomorphies in the male genitalia: robust pedestals with a widely rounded inner-posterior margin and a more acute and thinner outer margin, penes strongly sclerotised and curved ventrally, each lobe twisted outwards, and with a small membranous lobe on ventral margin. The nymphs of Campsurus major and C. argentinus and the female adult of C. major are described for the first time and illustrated here; the male adults of both species are redescribed. A new species, C. amapaensis, is described from male imagos. The following new synonymies are proposed: Campsurus argentinus Esben-Petersen (= C. pallidus Needham & Murphy, junior synonym) and C. major Needham & Murphy (= C. brasiliensis Traver, junior synonym). The nymphs of both species are reported to use silk to build soft cases and to glue substrate particles. A list of characters useful to distinguish the treated species from others in the genus is given.
