摘要

本文从系统发育的角度对湿足科(腹足纲:柱头足科)的染色体数目进行了综述。在吸湿体中，单倍体染色体数目在21到26之间。假设n = 21为家族祖先染色体数。湿螨科的模态单倍体数为23。本文首次从染色体数目和形态上描述了拟水蜗牛的核型。本种二倍体染色体数为2n = 46。核型是对称的，由21对常著心染色体和2对亚常著心染色体组成。核型公式为:2n = 42m + 4sm (n = 21m + 2sm)。基本数(FN)是92。染色体长度从最小的一对2.53 μm到最大的一对6.00 μm不等。二倍体互补体(TCL)染色体总长度为170.40±3.22 μm。

Check-list of chromosome numbers of the family Hygromiidae (Gastropoda: Stylommatophora) with new data on Circassina frutis

Chromosome number data on the Hygromiidae (Gastropoda: Stylommatophora) are summarized and reviewed briefly in the context of the phylogeny of the family. In hygromiids, the haploid chromosome numbers range from 21 to 26. It is supposed that n = 21 is the ancestral chromosome number in the family. The modal haploid number for Hygromiidae is 23. Description of karyotype in terms of chromosome number and morphology of hygromiid land snail Circassina frutis is provided for the first time. The diploid chromosome number of this species is 2n = 46. The karyotype is symmetric and consists of 21 pairs of metacentric and 2 pairs of submetacentric chromosomes. The karyotype formula is as follows: 2n = 42m + 4sm (n = 21m + 2sm). The fundamental number (FN) is 92. Chromosomes range in length from 2.53 μm for the smallest pair to 6.00 μm for the largest pair. The total length of chromosomes in diploid complement (TCL) is 170.40 ± 3.22 μm.

期刊介绍： Travaux du Muséum National d’Histoire Naturelle "Grigore Antipa" (The Journal of "Grigore Antipa" National Museum of Natural History) is an international, open access, peer-reviewed journal devoted to zoological research that is published biannually by the "Grigore Antipa" National Museum of Natural History from Bucharest (Romania). It publishes original research or review articles dealing with all aspects of general zoology (taxonomy, systematics, evolutionism, faunistics, zoogeography, palaeozoology, animal ecology, invasive species of animals, parasitism, biodiversity conservation). Also, some book reviews, anniversaries and obituaries of some personalities of science world can be accepted to be published in this journal. In the present, the only language accepted for this journal is English. The scope of the journal is to publish, disseminate and provide open access to the results of the original studies made in different zoological fields, in Romania and worldwide. Every submitted manuscript is subject to peer-review, being reviewed by at least two peers qualified to evaluate it. Distinguished authorities form the international advisory board which guarantees the high scientific profile of the journal.
