概述基因序列在双翅目蚤蝇科分子系统学研究中的应用。对蚤蝇科已测序的分类单元和基因序列进行了总结,12S rDNA和16S rDNA应用最广泛,涉及蚤蝇科17个属;获得基因序列最多的是Melaloncha属。蚤蝇科分子系统学研究内容为高级阶元系统发育分析、物种鉴定和隐存种发现。今后蚤蝇科分子系统学研究应增加蚤蝇标本的种类与数量,选择标准化基因。  相似文献

双翅目的蚤蝇科(Phoridae)属种繁多、分布广泛、形态特殊、习性多样,是一个研究较多又很不完善的类群。世界已知1500余种,我国只记载过57种,绝大部分在台湾,大陆仅广东、甘肃等省有零星记录。蚤蝇科有不少种类是为害菌蕈的,我们结合食用菌害虫的研究而积累了蚤蝇科的标本与资料;本文报道的屹蚤蝇属(Puliciphora)2新种就是在贵州得自蘑菇上的,新种模式标本保存在北京农业大学,虫标本室。  相似文献

The Phora of Costa Rica were reviewed and three species, all belonging to Schmitz's Group III, were recognized: P. americana Schmitz and Wirth, P. truncata new species and P. paramericana new species. Of the three species, P. americana is by far the most abundant, with the other two species being rarely collected. All specimens were collected in the central highlands of the country. The previous record of the Holarctic Region species P. stictica Meigen from Costa Rica was found to be based on a misidentification of P. truncata.  相似文献

A new genus is described for a new species, Obscuriphora sheppardi , collected in Warwickshire, England. The genus shows some resemblance to Plethysmochaeta Schmitz and Kuenburgia Schmitz. In the British fauna Obscuriphora is most likely to be confused with Conicera Meigen and Gymnoptera Lioy.  相似文献

The genus Phora (Diptera, Phoridae) includes more than 50 species widely distributed in temperate regions of Eurasia and Africa. Taxonomic identification of most species is based upon the morphology of the male hypopygium: hence for many species, including the type species of the genus, females are unknown. We used mitochondrial 16S ribosomal RNA sequences to match males with previously unidentified females from Phora atra , P. stictica , and P. holosericea . We then identified morphological characters that allow identification of females of P. atra and P. stictica without recourse to DNA sequencing. Our results show that small scale sequencing can aid in the development of taxonomic characters for use in the field to identify previously cryptic females. This iterative method of identifying populations genetically followed by re-examination of morphology should allow development of better keys for rapid identification of heretofore cryptic populations of insects. We also found that sequences from individual of P. holosericea from Cambridge, England and Malakhovka, Russia, were more similar to each other than to sequences from a conspecific fly also collected in Cambridge. This result suggests that there is previously un-suspected population structuring in this species.  © 2002 The Linnean Society of London, Biological Journal of the Linnean Society , 2002, 77 , 267–273.  相似文献

Three members of the red algal family Halymeniaceae (Thamnoclonium dichotomum (J. Ag.) J. Ag., Codiophyllum flabelliforme (Sond.) Schmitz, and C. decipiens (J. Ag.) Schmitz) are investigated. All are endemic to southern and southwestern Australia, possess basal stalks of substantial size and firmness, and are consistently associated with specific sponge taxa. In each case, the sponges are bonded by collagen-like fibrils to the host cuticle without modifying the algal tissue at the ultrastructural level. Secondary cortication and prominent growth rings occur in the stalks of all three species, and in each the pit plugs between cells become wider, more convoluted and less electron dense with increasing distance from the surface. Such pit plugs are apparently a unique attribute of the stalked Halymeniaceae. The three species share pit plug, sponge association and stalk morphological features but are not otherwise closely related, as they actually represent three distinct genera.  相似文献
