Abstract
A new genus and new species of pilumnid crab, Ericiolumnus symbioticus (Decapoda: Brachyura), is described from the sponge Callyspongia Duchassaing & Michelotti, 1864 (Porifera: Callyspongiidae) in reefs in Lombok, Indonesia. The new taxon is characterized, among several characters, by the unusual shape of the carapace, which possesses sharp anterolateral teeth armed with secondary spinules, and prominently spinulous ambulatory legs. Another pilumnid, Pseudactumnus pestaeBalss, 1933, is shown to be a junior synonym of Actumnus asper (Rüppell, 1830). The pilumnid genus PseudactumnusBalss, 1933 is additionally synonymised with ActumnusDana, 1851. A review of symbiosis in Pilumnidae is also presented.

摘要
印度尼西亚龙目岛礁中的海绵Callyspongia Duchassaing&Michelotti,1864年(Porifera:Callyspongiidae)描述了一种新的属和新的pilumnid蟹,Ericiolumnus symbioticus(Decapoda:Brachyura)。这种新的分类单元的特征是,甲壳的形状不寻常,甲壳具有锋利的前齿,并带有次级小刺和显着的多动腿。另一个比目鱼,Pseudactumnus pestae Balss,1933年,显示为Actumnus asper次要同义词(Rüppell,1830年)。1933年的pilumnid属Pseudactumnus Balss也被称为Actumnus达纳(Dana),1851年。还介绍了Pi科中的共生。
