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.

To the systematics and nomenclature of tenebrionid beetles of the tribes Phaleriini, Lachnogyini, Klewariini, and Blaptini (Coleoptera, Tenebrionidae)

The following new synonymies are established: Paranemia Heyden, 1892 = Taklamakania Ferrer et Yvinec, 2004, syn. n.; Paranemia schroederi Heyden, 1892 = P. argiropuloi A. Boga?ev, 1965 = P. argyropuloi A. Boga?ev, 1967, syn. n.; Paranemia bicolor Reitter, 1895 = Taklamakania lepetzi Ferrer et Yvinec, 2004, syn. n.; Lachnogya squamosa Ménétriés, 1849 = L. skopini Ferrer et Yvinec, 2004, syn. n. Placement of the genus Lachnodactylus Seidl. in the tribe Lachnogyini and the distinctness of the tribe Klewariini are substantiated. The larva of Agnaptoria anthracina G. Medv. is described.     

Révision de la tribu des Lachnogyini Reitter, 1904 sensu nov. et description d’un nouveau genre et d’une espèce nouvelle du désert de Taklamakan,Chine (Coleoptera : Tenebrionidae,Pimeliinae)

La tribu des Lachnogyini Reitter, 1904 sensu nov. est révisée. Les caractères distinctifs et la position systématique des genres Lachnogya Ménétriés, 1849, Netuschilia Reitter, 1904, Klewaria Reitter, 1916 et Lachnodactylus Seidlitz, 1898 sont discutés. La rotation de l’édéage dans l’abdomen, face ventrale visible de dessus, permet de l’inclure dans la sous-famille des Pimeliinae. Un genre nouveau de Lachnogyini, sous-famille des Pimeliinae (sensu Doyen & Tschinkel 1982), est créé pour recevoir une nouvelle espèce du désert froid de Taklamakan (Xing Kiang, Chine) : Taklamakania lepetzi, n. gen., n. sp. Une nouvelle espèce d’Afghanistan : Lachnogya skopini n. sp., est décrite. En revanche, le genre Lachnodactylus est transféré à la tribu des Trachyscelini en raison de la position ventrale de son édéage.     

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.     

New genera of philopotine spider flies (Diptera, Acroceridae) with a key to living and fossil genera

Information on the three previously described species of Halocoryza Alluaud is updated and a new species for the genus from Isla Carmen, Sea of Cortés, Baja California Sur, México is described. Halocoryza whiteheadianasp. n. was found at UV light on a beach of that island. This species does not fit the profile of the other three species, i.e., living on coralline beach sands, or in the Mangrove intertidal zone. Two alternative possibilities as to why this is so are suggested and a study plan for testing these possibilities is proposed.

A new cucullanid from the black grouper Mycteroperca bonaci (Osteichthyes: Serranidae) off the coast of Yucatán, México

Cucullanus mycteropercae n. sp. is described from the intestine of the black grouper, Mycteroperca bonaci Poey, from the northern coast of Yucatán, México. The new species is readily distinguishable from other Cucullanus species because it possesses an ellipsoidal papilla-like structure situated medially on the anterior cloacal lip of males. Other differentiating characters include the variable position of postcloacal pair 8 in males, the subventral position of phasmids, a slightly ventrally hooked posterior end of gubernaculum, and the presence of a large, cylindroconical sclerotized tail end in both sexes. This is the fourth record of a marine cucullanid off the Yucatán Peninsula in México belonging to Cucullanus Müller, 1777.     

Epigenetic heredity in mice: involvement of RNA and miRNas.

By contrast with a wide definition of the 'epigenetic variation', including all changes in gene expression that do not result from alteration of the gene structure, a more restricted class had been defined, initially in plants, under the name 'paramutation'. It corresponds to epigenetic modifications distinct from the regulatory interactions of the cell differentiation pathways, mitotically stable and sexually transmitted with non-Mendelian patterns. This class of epigenetic changes appeared for some time restricted to the plant world, but examples progressively accumulated of epigenetic inheritance in organisms ranging from mice to humans. Occurrence of paramutation in the mouse and possible mechanisms were then established in the paradigmatic case of a mutant phenotype maintained and hereditarily transmitted by wild type homozygotes. Together with recent findings in plants indicative of a necessary step of RNA amplification in the reference maize paramutation, the mouse studies point to a new role of RNA, as an inducer and hereditary determinant of epigenetic variation. Given the known presence of a wide range of RNAs in human spermatozoa, as well as a number of unexplained cases of familial disease predisposition and transgenerational maintenance, speculations can be extended to possible roles of RNA-mediated inheritance in human biology and pathology.La paramutation est une modification épigénétique héréditaire, découverte chez des plantes et récemment, chez la souris. C'est un changement héréditaire du phénotype associé avec un allèle sauvage à la suite de son passage dans une structure hétérozygote avec un allèle mutant (phénomène quelquefois appelé "conversation interchromosomique"). Souvent il est considéré comme une exception à la base de lois de Mendel, "les allèles sont retrouvés inchangés lors des ségrégations au cours des croisements". Au contraire la paramutation observée chez la souris résulte d'une modification de l'allèle sauvage du gène Kit après transmission à partir d'un hétérozygote avec un allèle mutant "insertion". Le phénotype des taches blanches visibles aisément par la couleur du pelage est transmis en absence de l'allèle inducteur sur plusieurs générations. Il est corrélé avec une diminution du niveau d'ARNm de Kit et une accumulation d'ARN de taille variable de Kit dans les spermatozo?des des souris paramutantes. La micro-injection de l'ARN de l'hétérozygote, ou de l'ARN et des microARN spécifiques de Kit dans l'oeuf fécondé induit le phénotype "taches blanches". Le r?le de l'ARN dans l'établissement et le maintien d'un état épigénétique héréditaire est proposé et discuté.     

Description of nine South American species of the genus Neralsia cameron, with low scutellar carina (Hymenoptera: Cynipoidea: Figitidae)

In this study a total of nine new species of the genus Neralsia are described for South America: N. desantisi Jiménez & Pujade-Villar n. sp., N. equilatera Jiménez & Pujade-Villar n. sp., N. hermafrodita Jiménez & Pujade-Villar n. sp., N. marioi Jiménez & Pujade-Villar n. sp., N. moisesi Jiménez & Pujade-Villar n. sp., N. obelix Jiménez & Pujade-Villar n. sp., N. parafossulata Jiménez & Pujade-Villar n. sp., N. pseudoneralsia Jiménez & Pujade-Villar n. sp. and N. rauli Jiménez & Pujade-Villar n. sp., all of them have in common the low carina separating the scutellar foveae. Other six known Neralsia species, N. albipennis (Kieffer), N. bogotensis (Kieffer), N. flavidipennis (Kieffer), N. fossulata (Kieffer), N. pilosa (Borgmeier) and N. striaticeps (Kieffer) have the same scutellar character. The morphological characters to differentiate all mentioned species are presented.
