Abstract

A new genus, Teramnonotus n. gen., is erected for Elamena gordonae Monod, 1956. The new genus includes two new species, T. johnlucasi n. gen., n. sp. and T. monodi n. gen., n. sp., described herein from eastern Australia (Queensland) and the southwestern Atlantic (Brazil), respectively. Teramnonotus n. gen. superficially resembles Elamena H. Milne Edwards, 1837, and Trigonoplax H. Milne Edwards, 1853, of which it can be easily distinguished by a combination of characters: eyes and ocular peduncle, rostrum, carapace, thoracic sternite 8 and thoracic pleurite 8, and the inhalant water openings. The validity of the obscure species Elamena mexicana H. Milne Edwards, 1853, is not supported and it is synonymised with Halicarcinus planatus (Fabricius, 1775).

摘要

一个新属，即Teramnonotus新属，为1956年的戈尔登伊拉梅纳蟹（Elamena gordonae Monod）而设立。该新属包括两个新物种，即分别在此描述的来自澳大利亚东部（昆士兰）的约翰·卢卡斯氏Teramnonotus蟹（T. johnlucasi新属、新种）和来自西南大西洋（巴西）的莫诺氏Teramnonotus蟹（T. monodi新属、新种）。Teramnonotus新属表面上类似于1837年的H. 米尔恩·爱德华兹的伊拉梅纳蟹属（Elamena）和1853年的H. 米尔恩·爱德华兹的三角板蟹属（Trigonoplax），通过以下特征组合可轻松将其区分：眼睛和眼柄、吻部、头胸甲、第8胸腹板和第8胸侧板以及进水口。1853年的墨西哥伊拉梅纳蟹（Elamena mexicana H. Milne Edwards）这一模糊物种的有效性未得到支持，它被同义化为扁平硬壳蟹（Halicarcinus planatus (Fabricius, 1775)）。
