摘要

1970年在越南北部石灰岩山上发现的半陆栖蟹属Tiwaripotamon Bott新种。Tiwaripotamon bellum n. sp.是该属中已知最大的种之一，其外部形态与越南北部的T. viet icum (Đăng & hnguyen, 2002)最为相似。然而，Tiwaripotamon bellum n. sp.可以很容易地通过其生活中较深的颜色，甲壳上有明显的鳃外齿，相对较短的活动角，以及雄性第一性腺末端的轻微弯曲的末端，具有近截形的尖端和结构近端的背叶来区分。

A new semiterrestrial crab from limestone hills in Vietnam (Crustacea: Brachyura: Potamidae: Tiwaripotamon).

A new species of semiterrestrial crab of the potamid genus Tiwaripotamon Bott, 1970, is described from limestone hills in northern Vietnam. Tiwaripotamon bellum n. sp. is one of the largest known species in the genus, and its external morphology is most similar to T. vietnamicum (Đăng & Hồ, 2002), described from northern Vietnam. Tiwaripotamon bellum n. sp., however, can easily be separated by its much darker colour in life, possession of a distinct epibranchial tooth on the carapace, the proportionately shorter ambulatory meri, and the gently curved terminal segment of the male first gonopod, with a subtruncate tip and dorsal lobe on the proximal part of the structure.

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
