美蓝蚜蝇属二新种记述(双翅目,蚜蝇科)

在整理美蓝蚜蝇属标本时发现2新种：缺纹美蓝蚜蝇Melangyna evittata sp.nov.,秦岭美蓝蚜蝇Melangyna qinlingensis sp.nov.,模式标本保存于陕西理工学院资源生物重点实验室,文中列出中国已知种的检索表。 缺纹美蓝蚜蝇,新种Melangyna evittata sp.nov.（图1 ～3） 雌性 未知。 ♂体长12mm;翅长10mm。 正模♂, 2004-05-05,陕西长安（太兴森林公园） ,霍科科采。 本种近似于Melangyna olsufjevi Violovitsh,但新种颜面暗棕褐色,缺黑色条纹,各足胫节棕褐色,缺亚端暗色环。新种以颜面暗棕褐色,缺暗色条纹命名,取拉丁字e（x）-（失去）和（vittatus）（具条纹的）构成新种名。 讨论新种颜面不具暗色条纹,符合亚属Meligramma特征,但后足基节后腹端角具毛簇,与该亚属特征不符;另一方面,后足基节后腹端角具黑色毛簇,符合亚属Melangyna特征,但颜面无黑色中条,与该亚属特征不符。所以其特征介于亚属Melangyna和Meligramma之间,其分类地位还有待进一步研究。 秦岭美蓝蚜蝇,新种Melangyna qinlingensis sp.nov.（图4 ～11） 雌性 未知。 ♂体长9.5mm;翅长9mm。 正模♂, 2002-07-07,陕西眉县（太白山） ,霍科科采。 本种近似于Melangyna olsufjevi Violovitsh,但新种复眼裸,颜面中条伸达触角基部,宽,小盾片被毛全黑色,足主要黑色,尾器不同。 新种以模式产地命名。

Review of Indian species of Monoceromyia Shannon (Diptera: Syrphidae) with description of two new species

Flower fly species of the genus Monoceromyia Shannon (Diptera: Syrphidae) in India are reviewed and two new species, M. flavoscutata Sankararaman, Anooj and Mengual, sp. nov. and M. nigra Sankararaman, Anooj and Mengual, sp. nov., are described from Tamil Nadu and Arunachal Pradesh (India), respectively. A new synonym is proposed: M. multipunctata (Hull, 1941) is synonymised under M. polistoides (Brunetti, 1923). Moreover, lectotypes are designated for Ceria patricia Brunetti, 1923 and Ceria tredecimpunctata Brunetti, 1923. An identification key to the Indian Monoceromyia species is also provided.     

Black-tie dress code: two new species of the genus Toxomerus (Diptera, Syrphidae)

Toxomerus hauseri Mengual sp. n. and Toxomerus picudus Mengual sp. n. are described from Peru and Ecuador respectively. Toxomerus circumcintus (Enderlein, 1938) is treated as a valid species and not considered synonym of Toxomerus marginatus, and Toxomerus ovatus (Hull, 1942) is considered junior synonym of Toxomerus nitidus (Schiner, 1868). An identification key for the Toxomerus species with dark abdomens is given along with diagnoses for each studied species.     

迷蛱蝶属及相关物种细胞色素b基因序列及其分子系统学研究

迷蛱蝶属Mimathyma隶属于蛱蝶科Nymphalidae闪蛱蝶亚科Apaturinae,该属所包含的种类复杂,其分类学地位存在争议.本文对迷蛱蝶属、闪蛱蝶属Apatura和带蛱蝶属Athyma7个种共19个个体的线粒体DNA细胞色素b基因部分序列进行测定分析,并以花斑螯蛱蝶Charaxes kahruba (Moore)作为外群用PAUP软件构建MP和NJ分子系统树.结果显示迷蛱蝶Mimathyma chevana(Moore)、夜迷蛱蝶Mimathyma nycteis(Ménétriès)、白斑迷蛱蝶Mimathyma schrenckii (Ménétriès)和环带迷蛱蝶Mimathyma ambica Kollar形成1个聚类簇,支持Moore将这4个种由闪蛱蝶属移出并建立迷蛱蝶属的观点.同时,尽管迷蛱蝶在形态上与该属其余3种相似,但研究发现聚类簇Ⅰ中夜迷蛱蝶、白斑迷蛱蝶和环带迷蛱蝶首先相聚,然后再与迷蛱蝶聚在一起,表明迷蛱蝶与这3种亲缘关系较远.此外,本文的研究结果还显示迷蛱蝶属与闪蛱蝶属关系密切,而与带蛱蝶属的关系较远.     

Terrestrial gastropods zoogeography in Southern Tamaulipas, México

Biogeography of Mexican terrestrial mollusks is poorly known, although many studies have described some of their biological aspects. This study aimed to contribute with new information on the distribution of terrestrial mollusks in this region of high altitudinal, topographic and climatic variations of Southern Tamaulipas State, México. For this, terrestrial gastropods were surveyed from December 1990 to November 2006. A total of 525 samples were obtained from 121 localities, characterized with different vegetation types. The primary zoogeographical feature was the presence of many endemic taxa, with 45 species or subspecies, representing the 43%, the highest value for Northeastern México. In addition, a total of 24 species (23%), were of Neotropical and Neartic distributions, and 15 species or subspecies (14%) exhibited Neotropical distributions. Furthermore, the family Spiraxidae showed the largest number of endemic species, with 17 species and two subspecies, and had the largest number of endemic species (27) for Northeastern México.

Paracreptotrema profundulusi n. sp. and P. blancoi Choudhury, Pérez-Ponce De León, Brooks, and Daverdin, 2006 (Trematoda: Allocreadiidae) from freshwater fishes of the genus Profundulus (Teleostei: Profundulidae) in southern México

Paracreptotrema profundulusi n. sp. (Trematoda: Allocreadiidae) is described from the intestine of the freshwater fishes Profundulus punctatus and P. balsanus (Teleostei: Profundulidae) from the Tehuantepec and the Atoyac-Verde River basins, in Oaxaca, México, in the western extreme of Central America. The new species is distinguished from Paracreptotrema blancoi Choudhury, Pérez-Ponce de León, Brooks, and Daverdin, 2006 , to which it is most similar, and from P. mendezi (Sogandares-Bernal, 1955) Choudhury, Pérez-Ponce de León, Brooks, and Daverdin, 2006 , by the caeca extending beyond the testes, vitelline follicles that invade the postesticular area, and uterus with transverse loops located mainly between the testes and the genital pore. Paracreptotrema blancoi was collected from the same host species and also from Profundulus oaxacae. Here, we provide data that show its broad distribution in several river basins of Neotropical southern México, including the Papagayo River basin, Guerrero, México, and the Atoyac-Verde and Tehuantepec river basins, and other rivers in Oaxaca, México. Freshwater fishes of the Profundulidae are endemic to Central America and host a helminth fauna that includes at least 4 species found only in these hosts.
