We describe Paradoxapseudes shimojiensis sp. nov. from a submarine limestone cave at Shimoji-jima Island, Ryukyu Islands, southwestern Japan. This species resembles five species (P. basibidens, P. bassoprofundo, P. bermudeus, P. edgari, and P. heroae, among 17 congeners) that bear a long pleotelson, but differs from them in having (i) a naked antennal article 1, (ii) the maxillipedal basis with one inner distal plumose seta, (iii) the chelipedal basis with one dorsodistal and one ventro-subproximal simple setae, (iv) the pereopod-1 basis with four dorsal simple setae longer than the width of the pereopod-1 basis, but without ventrodistal spiniform setae, (v) the pereopod-1 merus with three mid-inner ventral simple setae, and (vi) the pleopodal protopod with two inner plumose setae. We determined partial nucleotide sequences for the cytochrome c oxidase subunit I (COI) and 18S rRNA (18S) genes in P. shimojiensis for future use in DNA barcoding and phylogeny. Paradoxapseudes shimojiensis has serial ridges on the inner surfaces of the left and right chelipedal bases that quite resemble the stridulatory organs in harvestmen (Opiliones); by analogy, we speculate that these ridges may be stridulatory sound-producing organs. Two specimens had both a fully-developed marsupium and genital cone, suggesting that P. shimojiensis is simultaneously hermaphroditic.

我们描述了Paradoxapseudes shimojiensis sp。十一月 来自日本西南部琉球岛下岛岛的海底石灰岩洞穴。该物种与五种（P. basibidens，P. bassoprofundo，P. bermudeus，P. edgari和P. heroae）相似。，在17个同类动物中具有较长的胸骨，但与它们不同的是：（i）裸露的触角物品1，（ii）带有一个内侧远端羽状刚毛的set足基底，（iii）带有一个背背骨和一个的角膜基底腹旁近端简单的刚毛，（iv）有四个背侧简单刚毛的pereopod-1基，长于pereopod-1的宽度，但没有腹侧棘状刚毛，（v）腹腔近中的三个腹膜的pereopod-1简单的刚毛，和（vi）具两个内部羽状刚毛的腹足前足动物。我们确定了P. shimojiensis中细胞色素C氧化酶亚基I（COI）和18S rRNA（18S）基因的部分核苷酸序列，以供将来在DNA条形码和系统发育中使用。希莫吉悖论左右唇形基部的内表面有连续的脊，非常类似于收割者的毛状体器官（Opiliones）；通过类推，我们推测这些山脊可能是刺耳的发声器官。两个标本都具有成熟的有袋动物和生殖器锥，这表明西摩吉士同时具有雌雄同体的特性。
