Copepoda Cyclopoida

The genus Critomolgus Humes and Stock, 1983 represents a group of 34 species of copepods associated with marine invertebrates. Most of these species have been collected in associations with species of the phyla Cnidaria and Echinodermata in several localities in the Indian, Pacific and Atlantic Oceans with three species reported in the Mediterranean Sea. This is the first occasion in which a species belonging to the genus Critomolgus and the family Rhynchomolgidae Humes and Stock, 1972 is recorded for the Gulf of Mexico. Here, we describe a new species of marine copepod, Critomolgus walteri Varela, Price, Middlebrooks et Ambrosio, associated with the octocorals Leptogorgia virgulata (Lamarck, 1815) and L. hebes Verrill, 1869 in 3.3 meters of water in Tampa Bay, Florida. This species possesses characters that unite it with other members of the genus; however, it differs from all other species due to the body length and unique leg 5 and maxilla l characters. This new species provides evidence that much diversity remains to be discovered in the waters of the Gulf of Mexico and future sampling efforts should target this region.

A New Species

A new species of caridean shrimp of the family Alpheidae, Automate isabelae sp. nov., found in stomach analysis contents of the lane snapper Lutjanus synagris (Linnaeus, 1758), from the Keys and SW coast of Florida, Gulf of Mexico, is described. The abdomen and portions of the cephalic appendages were damaged in holotype, but remainder of the body and the chelipeds, whith the most important diagnostic characters are in decent or perfect condition, the description was further supplemented based on intact morphological parts of the paratypes. The presence of tubercles on the dorsal and ventral margins of the major chela palm, shows this new species to be related to the eastern Pacific Automate rugosa Coutière, 1902. Both congeners can be easily discriminated by the proportions and shape of the third maxilliped, the proportions and ornamentation of the carpus, merus, and chela of the major cheliped, the ventral seta of the carpus of the minor cheliped, the presence of a distoventral spine on the propodi of third and fourth pereopods, the armature of dorsal surface of telson, and their geographical distribution. The description of this new species increases the number of worldwide valid species known of the genus Automate to 12.

A New Species

Characidium samurai, a species of the family Crenuchidae apparently endemic to rio das Almas and rio Vermelho basins, Bahia, Brazil, is described. The new species is readily distinguishable from its congeners, except C. lanei, by having a dark lateral band along the head and body that is particularly broad from the rear of the head to the end of the caudal peduncle (1.5 or 2 scales wide) and by the absence of dark bars or blotches on the ventral half of the body. Characidium samurai differs from C. laneiby having the lateral band with straight borders overall (vs.lateral band with somewhat irregular borders due to blotches extending dorsally or ventrally), anal fin ii,7-8 (vs. ii,6), and 4 horizontal scale rows above the lateral line and 4 below (vs. 5/3). It further differs from congeners by a series of features, including isthmus completely covered by scales, lateral line complete with 34-37 perforated scales, 9 scales on the transversal line, 14 scale rows around the caudal peduncle, anal fin ii,7-8, and the absence of dark bars or spots on the fins, except by a faded dorsal-fin bar. The presence of pseudotympanum in four species of Characidium is discussed.

A New Species

A new species of the genus Thalassironus de Man, 1889 was discovered during several surveys of the offshore marine ecosystem in Korea. This new species belonging to the family Ironidae, Thalassironus koreanus sp. nov., shares general morphological traits of the genus such as an optically smooth cuticle, buccal cavity consisting of two parts with three movable teeth and thick cuticularized walls, six rounded lips with ten cephalic setae, slit-like amphid and short conical tail with caudal glands present. The new species is most closely related to T. bohaiensis, first discovered in the Bohai Sea, in terms of body ratio (a, b, c, c’) and general morphology, but differs by its generally longer and larger body structures, cervical setae at the level of the buccal cavity, paired somatic setae distributed along the body, and longer/larger spicule. A description of Thalassironus koreanus sp. nov., diagnosis of the genus, emended pictorial key for the genus and discussion of important characteristics for the genus is provided.

A New Species

In this paper we report a new species of Dendrocoelum from the chemoautotrophic ecosystem of the Frasassi hypogenic cave complex in the northeastern Apennines of Italy. Dendrocoelum leporii Stocchino & Sluys, sp. nov. is characterized by the presence of a muscular atrial valve, which is unique within the genus. Moreover, the new species is characterized also by a penis papilla with a pseudoflagellum, numerous testes situated in the ventral, dorsal and median body regions with the follicles extending to the far posterior end of the body, and a large adenodactyl with the so-called Balkan type of musculature. The new species represents the twelfth dendrocoelid species recorded for Italy. A summary is provided of the species of the family Dendrocoelidae Hallez, 1892 thus far reported for the mainland and the isles of Italy.

New taxa of the family Ropalomeridae from Costa Rica are described, and additional records of ropalomerid flies fromMexico and Central America are provided. The new genus and species Acrocephalomyia zumbadoi can be easily distin-guished from all other ropalomerid genera by the following combination of characters: angular forward projection of head,absence of ocelli, flat face, bare arista, long scutum, and scutellum triangular-shaped and dorsally flattened with only onepair of apical bristles with bases approximated. The new species Ropalomera aterrima can be recognized from congenersby remarkable differences of the head, the shape of the scutellum, the absence of scutal vittae, fumose wings, and by theblack coloration of the body, ocellar bristles large, one postpronotal bristle, scutum without pollinose vittae and flat scutellum. Lenkokroeberia chryserea Prado and Kroeberia fuliginosa Lindner are newly confirmed for Costa Rica.

The first finding of the genus Greeffiella Cobb 1922 (Greeffiellinae, Desmoscolecidae) in the Black Sea is presented. Two mature females were collected in Northwestern Shelf of Crimea in strongly silted fine sand with detritus at a water depth of 56 m. Greeffiella sp. is described and illustrated. The absence of males in the collections does not allow the authors to present it as a new species for science or to identify it as one of the known species of the genus Greeffiella. Black sea specimen is distinguished from the other known species of the genus Greeffiella with the presence of 8 pairs of thicker specific setae along the body, the basis of which looks like a small lamina, but without hairs, which was previously described for G. pierri Schrage & Gerlach, 1975 and G. australis Schrage & Gerlach, 1975. The short esophagus at the base has two salivary glands and a cardia. Cardia has not been mentioned before for the known species of the genus Greeffiella.

AbstractEctoparasitic nematodes (Acugutturus, Vampyronema and Noctuidonema) of the family Acugutturidae from 13 species of Lepidoptera (moths) and one species of Blattodea (cockroaches) were collected, measured and analysed by discriminant analysis in order to identify conspecifics and to determine which morphological characters were useful in defining differences between nematodes on different host species. The position of the excretory pore posterior to the metacorpus clearly differentiates Acugutturus parasiticus from Noctuidonema and Vampyronema. Two populations of A. parasiticus on Periplaneta americana from the West Indian islands of St Lucia and Guadeloupe are conspecific. Nematodes resembling Vampyronema, collected from two genera of Sphingidae in Guadeloupe are characterised by extremely long stylets, equal to ca 37% of the body length, and may represent a new genus. Noctuidonema from four species of Spodoptera (Noctuidae) are conspecific. However, a somewhat different Noctuidonema from the noctuid Pseudaletia unipuncta may represent a new species, based primarily on its shorter stylet length. Simple spicule structure, a smaller V percentage, and a shorter stylet in Vampyronema are characters that best define its differences from Noctuidonema. Nematodes on the noctuids Anicla infecta and Eulepidotis addens probably represent two new species of Vampyronema. There was no clear differentiation between nematodes on the noctuids Mocis disseverans, M. latipes, Agrapha oxygramma and Orthodes crenulata, and they are all probably conspecific with V.dibolia. Thus far, Noctuidonema has been found only on the trifine noctuids Spodoptera and Pseudaletia, whereas Vampyronema has been found on both trifine and quadrifine noctuids. We found evidence for sequential evolution, but not co-evolution, between these ectoparasitic nematodes and their lepidopteran hosts.

Sterlet Acipenser Ruthenus

Abstract A new species, Skrjabinopsolus nudidorsalis sp. nov. is described from the sterlet Acipenser ruthenus, caught in the River Volga basin (Russia). This species differs from previously described congeners by the absence of vitelline follicles on the dorsal side of the body. The complete 18S rRNA and partial 28S rRNA gene sequences obtained for S. nudidorsalis are the first molecular data for the family Deropristidae. The results of phylogenetic analysis indicate that Deropristidae is sister to the Monorchiidae + Lissorchiidae group. The results of the phylogenetic study contradict the current taxonomic hypothesis that Deropristidae belongs to the superfamily Lepocreadioidea and allow inclusion of this family in Monorchioidea. The morphological similarity of deropristids to other monorchioids is recognizable from the presence of a bipartite internal seminal vesicle, spinous cirrus and a voluminous, armed metraterm.
