记述中国围盾蚧属Fiorinia Targioni-Tozzetti 1新种:南宁围盾蚧Fiorinia nanningensis Zhang&Feng sp.nov.。该种近似于钩樟围盾蚧F.linderaeTakagi,1969,二者臀板均无腺刺分布,并且第2臀叶退化,略突起或全无,但是可以从以下特征区别:1)新种中臀叶狭小,末端截型,内缘无锯齿(钩樟围盾蚧中臀叶大而内缘多齿);2)躯干上无腺刺或腺瘤(钩樟围盾蚧后胸有1-3个腺瘤,第1腹节有3或4个腺瘤,第2腹节有1-2个腺刺);3)无触角间突(钩樟围盾蚧触角间突小圆锥形)。对其形态特征进行了详细描述,提供了玻片绘图。研究标本保存在西北农林科技大学昆虫博物馆。 相似文献

Coral taxonomy has entered a historical phase where nomenclatorial uncertainty is rapidly increasing. The fundamental cause is mandatory adherence to historical monographs that lack essential information of all sorts, and also to type specimens, if they exist at all, that are commonly unrecognizable fragments or are uncharacteristic of the species they are believed to represent. Historical problems, including incorrect subsequent type species designations, also create uncertainty for many well‐established genera. The advent of in situ studies in the 1970s revealed these issues; now molecular technology is again changing the taxonomic landscape. The competing methodologies involved must be seen in context if they are to avoid becoming an additional basis for continuing nomenclatorial instability. To prevent this happening, the International Commission on Zoological Nomenclature (ICZN) will need to focus on rules that consolidate well‐established nomenclature and allow for the designation of new type specimens that are unambiguous, and which include both skeletal material and soft tissue for molecular study. Taxonomic and biogeographic findings have now become linked, with molecular methodologies providing the capacity to re‐visit past taxonomic decisions, and to extend both taxonomy and biogeography into the realm of evolutionary theory. It is proposed that most species will ultimately be seen as operational taxonomic units that are human rather than natural constructs, which in consequence will always have fuzzy morphological, genetic, and distribution boundaries. The pathway ahead calls for the integration of morphological and molecular taxonomies, and for website delivery of information that crosses current discipline boundaries. © 2013 The Author.

A comparison among 20 genera, representatives of Sophoreae, Thermopsideae and Genisteae based on the serological cross reactivity of the seed proteins, indicates: (a) Sophoreae are highly heterogeneous – there is little similarity among genera of the New World, genera of tropical austral Africa, and genera of temperate Eurasia; (b) Sophora and Maackia are strictly related both to Thermopsidae and to Genisteae; (c) Thermopsideae are not intermediate between Sophoreae and Genisteae; (d) Primitive Thermopsideae and Genisteae (Anagyris, Hesperolaburnum) are serologically related among themselves and to the Sophoreae; (e) derived herbaceous genera (Baptisia, Lupinus) are serologically divergent. 相似文献

A revision of part of the genus Paratylenchus is reported covering those species with stylets averaging < 22 μm. Thirteen new species are described and further observations are given on the morphology and relationships of nine other species. Paratylenchus gahriciis transferred to the genus Hemicriconemoides. This article is the first of three parts: the second will treat Paratylenchus spp. with stylets averaging 24-40 μm (and include a key to the species described in parts 1 and2), the third will include species with stylets >40μm, respectively. 相似文献

The nematode Drilomermis leioderma n. gen., n. sp. (Merrnithidae) is described from larvae of Cybister fimbriolatus (Say) (Dytiscidae: Coleoptera) in Louisiana. Diagnostic characters of the genus Drilomermis are: medium-sized nematodes with the cuticle appearing smooth (lacking cross fibers) under the light microscope, six cephalic papillae, without mouth papillae, six hypodermal cords at midbody, 2 extremely long spicules (longer than 10 times body width at anus) which are separate and parallel (not twisted), an S-shaped vagina, medium-sized amphids located near head papillae, and postparasitic juvenile with a tail appendage. D. leioderma possesses a ventrally displaced mouth, very long vagina, and male genital papillae arranged in 3 double rows in the vicinity of the cloacal opening. Even when containing multiple parasites, about 40% of the hosts sulwived emergence of the memithids and lived several more days. In nature, some of these hosts may be able to continue their development, which is unusual since most mermithid-parasitized hosts die soon after the nematode emerges. 相似文献

Part III covers species with female stylet length >41 μm which are considered by this author to comprise the genus Gracilacus Raski, 1962. Seven new species of Gracilacus are described and further observations given on 14 other species. Paratylenchus strenzkei (Volz, 1951) Oostenbrink, 1960 is transferred to species inquirendae. A key to the species of Gracilacus is included. 相似文献

Four new species of the genus Hemicriconemoides (H. californianus n.sp., H. taiwanensis n.sp., H. annulatus n. sp., and H. nitida n.sp.) are described. The range of total length of H. mangiferae is increased on the basis of specimens collected in Israel, Observations on H. mangiferae and H. litchi support the validity of H. litchi as distinct from H. mangiferae. 相似文献

Antarctylus humus n. gen., n. sp. from peat soil in the subantarctic is proposed. It can be distinguished from the most closely related genus Helicotylenchus by the arrangement of the esophageal glands, the broadly rounded lip region, and the tapering pointed tail in the female. 相似文献

The classification of the Neotropical genera of the Geometrinae is reviewed and 38 genera are recognized (including one nomen dubium). Seven generic synonyms are newly established and the genus Gnathosocia is described as new. Other changes established in this work include 1 species synonym and 36 new or reinstated combinations. A key to genera, based on external features, is provided for their identification. External features and genitalia of representatives of each genus are illustrated. All the 506 known Neotropical species and subspecies of Geometrinae are catalogued and details of type material, examined extensively, are given. 相似文献
