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.  相似文献

Two new species of the genus Eumyllocerus Sharp, 1896, of the subfamily Entiminae Schoenherr, 1823, are described from China. Eumyllocerus longisetus sp. n. may be distinguished from other species of the genus by its long bristle-like, erect setae on the intervals, each of which is longer than the width of the second interval, the setae arrangedin double rows, and its shell-like, shiny, dense, metallic green scales. Eumyllocerus rotundicorpus sp. n. may be distinguished from any other Eumyllocerus species by its oval and inflated elytral shape, short stout metepisternum, small humeri, elytral setae shorter than 0.5 times the width of the second interval, the setae arranged in double rows, and its golden copper and pearl gray scales. The taxonomy of the genus is discussed. The two new species are described and habitus photographs and figures of diagnostic characters are provided. The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China (holotype and paratypes) and the Korean Entomological Institute, Korea University, Seoul, Korea (paratypes).  相似文献

A new genus Amblomma gen. nov. of fossil beetles is erected and can be assignedto the family Ommatidae because its two procoxal cavities are contiguous and the articulations of the abdominal ventrites are abutting. The new genus is similar to Zygadenia Handlirsch, 1906 (=Notocupes Ponomarenko, 1964), Tetraphalerus Waterhouse, 1901,Rhobdocupes Ponomarenko, 1966 and Sinocupes Lin, 1976, but can be distinguished from other genera according to the following characters: the second segment of antennae is shorterthan the third one in length; the posterior tarsi with the basal segment is obviously shorter than the three following taken together in length; the antennae reach the posterior ridge of prothroax in length, and the sides of the prothroax with serrulate margin. Four new species of the new genus are described and figured: Amblomma psilata gen. et sp. nov., Amblomma rudis gen. et sp. nov., Amblomma epicharis gen. et sp. nov., and Amblomma stabilis gen. etsp. nov. A key to species within this new genus is provided. All the specimens are collected from the Late Jurassic Yixian Formation of western Liaoning and are now housed in the College of Life Science, Capital Normal University, Beijing, China.  相似文献

Glycosmis longipetala F. J. Mou & D. X. Zhang is described from Guangxi and Yunnan provinces in southwestern China. The new species is similar to G. cochinchinensis (Lour.) Pierre ex Engl. by its simple leaves, but distinguishable in having long-elliptic or oblanceolate (vs. ovate) leaves, long-ovoid to ellipsoid (vs. ovoid) floral buds, ovaries with many tubercles (vs. smooth) and glabrous (vs. pubescent) stamens. The pollen grains of the new species are 23.9±3.09 (20.8-27.0)×22.0±1.80 (20.4-24.4)μm in size with reticulate exine ornamentation in equatorial area and foveolate in polar area. The chromosome number of the new species is 2n=72.  相似文献

A new kind of marattialean raches are reported from the coal balls in Coal Seam No.7 in the upper part of the Taiyuan Formation (early Early Permian) from Taiyuan, Shanxi, China and are assigned to the genus Stipitopteris Grand'Eury (Psaroniaceae). The present specimens are different from all six reported species of the genus, and are therefore proposed as a new species: Stipitopteris shanxiensis. The raches of the new species are generally dorsi-ventrally flattened. The main raches usually exhibit scales of different forms on their surface. Beneath the epidermis is a zone of parenchymatous cells, some of which contain tannin-like contents. Inside this is a zone of small sclerenchymatous cells. Inward are the ground tissue and vascular bundles. The vascular bundles are continuous and are in two circles: the outer circle assumes a transversely elliptical shape with the gap and pinna trace, and the inner circle assumes a shallow C.shape with inrolled ends. The ground tissue located at the inner side of the vascular bundle is composed of thicker-walled parenchymatous cells. The cells of the ground tissue are vertically elongated in longitudinal sections. Subordered raches are smaller and have simpler structures than the main raches. The parenchyma zone beneath the epidermis is thinner, usually one to two cells wide and the sclerenchyma zone is usually absent. The scales are poorly developed and there is only one C-shaped vascular bundle. The new species is comparable to the crosiers of Psaroniaceae of the Euramerican Flora in some aspects, for example, it has a dorsi-ventrally flattened rachis and scales on the surface of the rachis. However, the other features and the preservative conditions of the present specimens indicate that they are not crosiers, but fully developed or mature raches. The new species is the first well-studied anatomically-preserved rachis of Psaroniaceae from the Cathaysian Flora and bears significance not only in understanding the anatomy and taxonomy of Psaroniaceae in the Cathaysian Flora, but also in the relationship between the Euramerican Flora and the Cathaysian Flora.  相似文献

We describe a new species from the family Salamandridae from northeastern Hunan Province of China based on morphological and molecular genetic evidences.The new species,Tylototriton liuyangensis,is a member of the T.asperrimus group,and shares a number of similarities with T.wenxianensis and T.broadoridgus.The dorsal surface of the new Tylototriton species is completely black,with nodule-like warts distributed evenly along the lateral margin of dorsal body,and there is no transverse striae between the warts.There are several diagnostic characters of the new species that differ from those of T.wenxianensis and T.broadoridgus as follows:(1)the interorbital space(IOS)is comparatively wide;(2)there is a bony ridge present on the dorsal head surface,running along the upper eyelids;(3)the space between axilla and groin(AGS)is comparatively large,with the mean male AGS approximately equal to 50%of the snout-vent length(SVL)and the mean female AGS being 53%of SVL;and(4)there is a small genital armature on the anterior angle of labial folds present inside the anal fissure of adult males during the breeding season.The result from the molecular phylogenetic analysis of the genus Tylototriton(including the type specimen of the new species)based on the complete DNA sequence of the mitochondrial ND2 gene(1035 bp)indicated that the new species was similar to T.wenxianensis,T.dabienicus,and T.broadoridgus,but formed an independent clade.This result was consistent with the morphological analysis above,supporting that the Liuyang Population represented a distinct species.  相似文献

The genus Kisaura Ross, 1956 (Trichoptera, Philopotamidae, Philopotaminae) is reported from India the first time. Six new species are described and illustrated: Kisaura elongatasp. n., Kisaura eloctsp. n., Kisaura clavatasp. n., Kisaura gangtokensissp. n., Kisaura truncatasp. n., all from Gangtok (Sikkim) and Kisaura himachalicasp. n. from Barot (Himachal Pradesh). Male genitalia of this genus are distinguishable from those of other genera of the family by the pair of long lateral processes of tergum X, the well-developed mesoventral plates between two segments of the inferior appendages, and by the brush-like row of dark setae on the inner surfaces of the terminal segments (harpago) of the inferior appendages.  相似文献

Abstract. A revision and phylogenetic analysis of the Neotropical genus Chimarrhodella Lestage is presented. Four described species are recognized, C.galeata (Martynov), C.peruviana (Ross), C.ulmeri (Ross) and C.nigra Flint. In addition, five new species are described, C.costaricensis sp.n. (Costa Rica), C.tapanti sp.n. (Costa Rica), C.flinti sp.n. (Venezuela), C.pilcopata , sp.n. (Peru) and C.tobagoensis sp.n. (Tobago). These species are organized into two monophyletic species groups, designated here the Galeata Group and the Peruviana Group. The Galeata Group is characterized by having male genitalia with tergum X possessing well developed lateral lobes bearing sclerotized, spine-like processes and includes C.galeata, C.costaricensis, C.flinti, C.pilcopata and C.tapanti. The Peruviana Group is characterized by having male genitalia with tergum X only slightly divided apically, tergum IX bearing hook-like processes posteriorly, and female genitalia with segment VIII much elongated in comparison to the Galeata Group and includes C.peruviana, C.nigra, C.tobagoensis and C.ulmeri. Records of the genus from Costa Rica and Tobago represent significant extensions of the known range for the genus, previously unknown north of Panama. A key to males and known females and a species-level phylogenetic analysis are included.  相似文献

A new species, Ctenophthalmus (Euctenophthalmus) parthicus sp. n., is described from social vole (Microtus socialis Pallas) from four localities of the West Kopetdag Mountains of Turkmenia. The new species is close to C.(E.) secundus Wagner and C.(E.) congener nadimi Farhang-Azad. It differs from males of the other known species by the following characters. The movable process has an infra-acetabular process whose length is the same as the height of its supra-acetabular portion. The movable process has the straight front margin, right anterior apical angle. The anterior part of the dorsal margin of the movable process is elevated, the hind part is slightly concave. The posterior apical angle of the movable process is cut. The hind margin of the movable process is convex. The apex of the distal arm of sternum IX is straight, not oblique. The female differs by the following peculiarities. Sternum VII has a well developed dorsal lobe below which there is a smaller rounded lobe and a distinct small ventral process. Unciform sclerotization of tergum VIII (or the place of connection between tergum VIII and its internal lobe) resembles an arc. The front margin of the internal lobe of tergum VIII is not sclerotized. The bursa copulatrix is as long as the dorsal spines of pronotum.  相似文献

A new species of Baetidae, Gratia baibungensis sp. n., is described and illustrated based on nymphal stage collected from the southeastern Tibet (Xizang) and the genus is reported for the first time from China. This new species can be readily differentiated from its congeners by the absence of a protuberance on the posterior margin of the abdominal tergum X, glabrate simple submarginal setae on the labrum, and the posterior margin of sterna VI–IX having much longer spatulate setae.  相似文献
