Abstract Delavalia qingdaoensis, a new species of harpacticoid copepod of the family Miraciidae is described based on specimens sorted from sediment samples collected in Jiaozhou Bay, Qingdao, Shandong Peninsula, Yellow Sea, in May 2008. The new species is easily distinguished from its congeners by the combined characters of the antennulary segments, an apomorphic setal formula of the swimming legs, and the shape of P5 in both sexes. It is remarkably similar to D. bocqueti (Soyer, 1971) and D. latioperculata (Itô, 1981), but it differs from D. bocqueti by features of the caudal rami, antennule, antennary endopod, mandibular exopod, maxillipedal basis, and P5 endopodal lobe; from D. latioperculata by the caudal rami, the inner setae of P1-P4 enp-1, P2 enp-2, and P4 exp-3, and the shape of P5 in both sexes.

A New Species

A new species of the continental shelf hyperbenthic genus Pilarella is described, the first from the Indo-Pacific. This is the second species of Pilarella known, and the first description of a male in the genus. The new species is easily distinguished from other species of Pilarella (P. longicornis) based on: (1) short caudal rami, approximately 1.5 times longer than wide; (2) 2 setae on the mandibular endopod; (3) 6 setae on the maxillular coxal epipodite; and (4) in the female, a short left antennule reaching the posterior border of the genital double-somite. The new diagnosis of Pilarella differs from Metacalanus in the separation of ancestral segments IX–XII and XIV–XV of the antennule, and the presence of 5–6 setae on the maxillular praecoxal arthrite. Pilarella is also separated from Metacalanalis based on the absence of a seta on the third ancestral segment of the antennary exopod, the symmetry of legs 1–3, the presence of a medial basal seta on the female leg 5, and 2 lateral exopodal spines on the female leg 5. A molecular phylogenetic analysis of some representative genera of the family Arietellidae, including the present new species, recovers two arietellid clades (Metacalanus- and Arietellus-clades) as in previous studies. Dichotomous keys for the genera of Arietellidae and the species of Pilarella are included.

AbstractA new anisakid nematode, Hysterothylacium liparis sp. nov., is described from the intestine and stomach of the fish, Liparis tanakae (Gilbert et Burke, 1912) (Scorpaeniformes, Liparidae), a fish endemic to the Yellow Sea, China. The new species can be distinguished from the congeners by the absence of lateral alae, the length of the intestinal caecum (1.94–3.35 mm, 58.84–82.47% of oesophageal length), the number and arrangement of the caudal papillae (20–29 precloacal subventral pairs, 1 adcloacal pair and 4 postcloacal pairs), the size of the spicules (1.94–3.74 mm, 4.85–7.30% of body length) and the morphology of the tail tip. This is the first species of adult ascaridoid nematodes to be reported from fishes of the family Liparidae in northern China.

A new harpacticoid copepod is described from the waters off Jeju Island, Korea. This species displays a unique set of characteristics including a rostrum that is clearly demarcated from the cephalosome, a setular (spinular) row on the rostrum, a well-developed frill along the posterior margins of each body segment except for the cephalosome, long and cylindrical caudal rami, four segmented female antennules, paired genital apertures in the female, the absence of sexual dimorphism in legs P1–P4, and highly reduced P5 and P6 in the male. This combination of characteristics allocates the specimen to the family Nannopodidae Por, 1986, but the new species belongs to none of the extant genera within the family. A new genus, Doolia, is proposed. Nannopus is suggested as a sister taxon of the new genus based on shared plesiomorphic characteristics in the maxilliped, legs P1–P4, and P5. Doolia gen. nov. is the eighth genus of Nannopodidae, and an amended key for the genus is provided herein.

A New Species

A new species of harpacticoid copepod, Dactylopusioides malleus sp. nov., belonging to the family Thalestridae is described from central Japan. The species is obligately endophagous in dictyotalean brown algae (Dictyota dichotoma (Hudson) J.V. Lamouroux, Dictyota maxima Zanardini and Dictyopteris undulata Holmes). The species nests by burrowing into the algal tissue during the copepod naupliar stages, while copepodids and adults reside in a dome-shaped, transparent capsule made of mucus and formed on the algal tissue. In laboratory experiments, the new species progressed through its complete life cycle (i.e. from egg to adult) while feeding only on unialgal dictyotalean tissues; this confirmed the obligate relationship with the host. The new species shares the following morphological characters with other species of Dactylopusioides: 1) antennary exopod 1-segmented; 2) first segment of P1 endopod in female elongated with a long seta on the inner proximal margin; 3) baseoendopod and exopod of P5 in female with five setae. It differs from other species in the following ways: 1) antennary exopod with six setae; 2) a stout hammer-shaped inner spine on the basis of P1 in male; 3) terminal short seta on third segment of P2 endopod in male is plumose.

A new species of harpacticoid copepod was discovered on submerged mosses of a high Andean lake in Colombia. The diagnostic characters of the male and female canthocamptidElaphoidella paramunan. sp. are based on the chaetotaxy of legs 1 to 4, morphology of leg 5, armature of anal urosomite, size and armature of anal operculum and morphology, armature and ornamentation of caudal rami. It belongs to the group X of Lang (1948); its relationships withElaphoidella pectinata,E. armataandE. brevifurcataare discussed. The 35 species and subspecies ofElaphoidellaknown in the Neotropical region are assigned to groups I, II, VII, VIII and X of Lang’s system (1948). Identification keys to ColombianElaphoidellaspecies are provided.

The genus Rapisma McLachlan, 1866 (montane lacewings) is a rare and little known group of the family Ithonidae (Insecta: Neuroptera). There have been 21 described species of Rapisma, and all of them are distributed from East Asia, South Asia and Southeast Asia. Here I report a new species of Rapisma from northwestern Yunnan, China, namely Rapisma weixiense sp. nov. The new species belongs to a group of Rapisma species with very short antennae.

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.
