“…But, as this species lacks remarkable troglomorphic features in the external morphology (such as the elongation of locomotory and sensory appendages; cf. García-Herrero et al, 2018 ), this species may also be found in open marine environments.…”

“… García-Herrero et al (2018) summarized the ecological information of tanaidaceans with reports from marine subterranean environments (e.g., submarine caves and anchialine pools), and showed that most species were not restricted to such environments, i.e., they have reports from open marine environments. In the Pacific, three of four species with report(s) from submarine caves were also collected from the outside of caves ( Bamber, 1997 ; García-Herrero et al, 2018 ). This study reported H. shimojiensis sp.…”

“…To date, submarine-cave tanaidaceans have been reported from six regions in the Northern Hemisphere ( Fig. 1 ), and 16 species in 14 genera (including one taxon identified at the genus level) have been recorded ( Table 1 ) ( Băcescu, 1980 ; Guţu & Iliffe, 1985 , 2001 , 2008 ; Bamber, 2000 ; Bird & Bamber, 2000 ; Bamber & Sheader, 2003 ; Akoumianaki & Hughes, 2004 ; Bamber, Evans & Robbins, 2008 ; Navarro-Barranco et al, 2013 , 2015 ; Gerovasileiou et al, 2016 ; García-Herrero et al, 2018 ). From the Pacific Ocean, four species have been reported so far: Paradoxapseudes mortoni ( Bamber, 1997 ) in Apseudidae; Tanapseudes ormuzana Băcescu, 1978 in Kalliapseudidae; Unguispinosus hodgsoni ( Bamber, 2000 ) in Parapseudidae; and Paratanais clarkae Bird & Bamber, 2000 in Paratanaidae.…”

We establish a new pseudozeuxid genus Haimormus gen. nov. based on a new species Haimormus shimojiensis sp. nov. which was collected from a submarine limestone cave with the entrance at 35 m depth, in the Northwestern Pacific Ocean. H. shimojiensis differs from the other confamilial members, Pseudozeuxo belizensis Sieg, 1982 and Charbeitanais spongicola Bamber & Bird, 1997, in having the pleonite 1 without the pleopod, the pereopods 2 and 3 propodus with a ventral spiniform seta, and the pereopods 4–6 propodus with one long and two short dorsodistal setae. A key to females of species of Pseudozeuxidae is presented. This is the first tanaidacean report from submarine caves around Japan.

“…Since the pioneering work by Băcescu (1980), 17 species of tanaidaceans in genera have been reported from submarine caves (Kakui and Fujita 2018;Kakui et al 2019), although most of these species are not restricted to caves (García-Herrero et al 2019).…”

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.

“…In taxonomic studies, the chaetotaxy of various appendages has been used for many crustaceans such as amphipods, isopods, ostracods, tanaidaceans, and copepods (Wells, 2007;Brad et al, 2015;Kim, Lee & Karanovic, 2017;García-Herrero, Sánchez & García-Gómez, 2019;Yoo et al, 2019). In taxonomy of copepods in particular, the arrangement, size, and type of setae and spines on the swimming legs are used as major keys for species identification (Huys et al, 1996;Chihara & Murano, 1997;Wells, 2007).…”

We collected an undescribed laophontid copepod from a coarse sand habitat on the east coast of Korea and named it Quinquelaophonte enormis sp. nov. We compared the detailed morphological characteristics of the new species with those of congeneric species. Among them, the new species shows a superficial resemblance to the Californian species Quinquelaophonte longifurcata Lang, 1965. However, the two species are easily distinguishable by the setation of the syncoxa on the maxilliped and the fourth swimming leg. The new species has the variable setation on the second to fourth swimming legs. The variations appear among individuals or between the left and right rami of a pair of legs in a single specimen. Although complex chaetotaxical polymorphism occur in this new species, we used myCOI and Cytb to confirm that the new species is not a species complex. Also, partial sequences of 18S and 28S ribosomal RNA genes were used to analyze the position of the new species within the family Laophontidae. The new speciesis the fourteenth Quinquelaophonte species in the world and the second species in Korea.
