We describe a new harpacticoid, Stammericaris remotaepatriae sp. nov., collected from the hyporheic habitat of a stream in Nantucket, MA, USA. The new species is characterized by the size of the caudal rami of both sexes, which are shorter than the anal somite, by the morphology and armature of the P3 and, mainly, by the P4 endopod of males, represented by a curved plate with a strongly bifid tip, the distal proximal outgrowth of the distal margin spiniform and denticled, the proximal outgrowth missing. The study of the new species allowed us to review the systematic position of Parastenocaris palmerae Reid, 1992, which we transferred to Stammericaris Jakobi, 1972 as Stammericaris palmerae (Reid, 1992) comb. nov., based mainly on the structure of the male P4 endopod complex and the setation of the caudal rami. We also discussed the taxonomic position and affinities of Parastenocaris trichelata Reid, 1955, suggesting that this species is related to the two former ones for a set of diagnostic features, but can not be attributed to the genus due to the peculiar morphology of the male P4 endopod complex; P. trichelata is therefore considered species inquirenda. We also discussed Parastenocaris sp. 1 and Parastenocaris sp. 3, two taxa only partially described and drawn in Strayer (1988). In fact, Parastenocaris sp. 1 can be related to Stammericaris and might represent a third species of the genus in the Nearctic region. Remarkably, the structure of the male P4 endopod of Parastenocaris sp. 3 is typical of Proserpinicaris Jakobi, 1972; this hypothetical assignment of the species to Proserpinicaris, if confirmed, would be of relevant taxonomic and biogeographic value. Finally, we provide an updated distribution map of the genus Stammericaris and brief remarks on the faunistic and ecological characteristics of the taxa presented and discussed in this paper.

A New Species

A new aegisthid copepod, Cerviniopsis reducta sp. nov. is described from the deep sea in Sagami Bay, Japan. The newspecies has superficial resemblance to C. minutiseta Ito, 1983 in the armature formula of swimming legs. However theydiffer from each other in the shape of setae of the swimming legs, the distal margin of operculum, length of caudal rami,and the location of setae on P5 exopod. Also, the male of Neocervinia itoi Lee & Yoo, 1998 is described on the basis ofsamples collected from around the type locality in Sagami Bay, Japan. Sexual dimorphism of N. itoi male can be observedin the fused rostrum, atrophied mouthparts, P5, and P6. The sixth leg is symmetrical and both gonopores are presumablyactive, based on the presence of two spermatophores internally in the genital segment. This paper reports for the first timeon the sexually dimorphic characters in the genus Neocervinia Huys, Mobjerg & Kristensen, 1997, reinstating its generic status with the newly revealed male characters.

The Fannia carbonaria-subgroup belongs to the Fannia carbonaria-group Chillcott, 1961. The world fauna of this subgroup is reviewed, the diagnostic features of the subgroup are redefined, and a key to the males of the known species is given. Two new species from China are described: F. dorsovittata Wang sp. nov. and F. subfuscitibia Wang sp. nov.. To facilitate comparisons of the species, Fannia corvina (Verrall), Fannia imperatoria Nishida and Fannia xiaoi Fan are redescribed. Geographic distributions of the species of the subgroup are updated. The systematic position and distribution patterns of the F. carbonaria-subgroup are discussed.

AbstractThe Holarctic Scopula cajanderi (Herz) species group is revised on the basis of external and genitalic characters. The taxa included in the species group are Scopula cajanderi (Herz, 1903 [not 1904]) (= the Palaearctic Scopula elwesi sajanensis Prout, 1935 syn.nov., = the Palaearctic Scopula elwesi achlyoides Prout, 1935 syn.nov., = the Nearctic Scopula septentrionicola McDunnough, 1939 syn.nov.), thus making S. cajanderi Holarctic; Scopula mustangensis Yazaki, 1995; and Scopula aegrefasciatasp.nov. Lectotypes are designated for the following species which were described from more than one specimen without holotype designation: S. cajanderi, Scopula anaitaria (Herz, 1903), and S. e. achlyoides. The systematic position of Scopula elwesi elwesi Prout, 1922 within the genus Scopula is uncertain. A key to the species is presented with illustrations of the adults and genitalia, and a distribution map is presented for all taxa. An examination of the biogeography of S. cajanderi suggests that the Wisconsinan and Sartan glaciations may have played a part in the origin of the disjunct populations.

Abstract Electromyrmex wheeleri sp. n., which belongs to the extinct ant genus is described based on males from the Baltic and Bitterfeld Ambers (Priabonian stage, 33.9-37.2 Ma). Until now only one species of this specialized genus based on a single worker was described and taxonomic position of this genus in the subfamily Myrmicinae remains uncertain. By the forewing venation, males of E. wheeleri resemble Aphaenogaster Mayr, Messor Mayr and Pheidole Westwood, but diff ers from the fi rst two genera by the presence of Mayrian furrows, and from the latter one - by the antennal structure. On the other hand, males of this genus have a set of specialized characters, e. g., subcylindrical petiole, mandibles with an only single apical tooth, quite peculiar shape of mesosoma, etc. and the morphological features of the males of E. wheeleri also do not shed light on its systematic position.

Hamadiana chapadensis gen. n. and sp. n. is described based on a single male specimen collected in Central Brazil. The new species belongs to the diving beetle tribe Laccophilini but could not be assigned to any existing genera, therefore a new genus is described to accommodate it. Hamadiana gen. n. is unique among Laccophilini in having the hind margin of the metacoxal process deeply incised and medially slightly protruded backwards. In addition, it differs from other genera of the tribe by having the antennomeres simple, not expanded, the metacoxal lines not straight, and the metatibiae with two simple apical spurs. The habitus, male genitalia, and diagnostic features are illustrated, and a distribution map is provided. A recently published key to Laccophilini is modified to include the new genus.

Maraenobiotus wellsi sp. nov. (Canthocamptidae) is described based on material collected in mosses in the “páramo” region of the Andean Cordillera of Colombia. The new species is closely related to M. australis Apostolov, 2001 from Tierra de Fuego in Argentina, but can be distiguished by the shape of the caudal rami, the insertion point of its terminal seta IV, and the chaetotaxy of distal segments of legs 3 and 4. We discuss morphological differences with other congeners inhabiting South America (Peru), i.e. M. naticochensis Delachaux, 1917, M. fontinalis Harding, 1955 and M. fontinaloides Löffler, 1960. Major distinguishing features were observed in the chaetotaxy of legs 2 and 3, the morphology and size of the caudal rami, and the ornamentation of the anal operculum. We also discuss morphological characters that distinguish the new species from those living exclusively in mosses, such as M. cuspidatus Štěrba, 1968 and M. canadensis Flössner, 1992, and those reported from mosses and other habitats i.e.. M. vejdovskyi Mrázek, 1893, M. brucei brucei (Richard, 1898), M. zschokkei Kreis, 1920, M. brucei himalayensis Chappuis, 1928b, M. truncatus (Gurney, 1932), M. insignipes elgonensis Chappuis, 1936, M. insignipes nepalensis Löffler, 1968 and M. kinabaluensis Löffler, 1973. A distribution map of American species and an identification key for females are provided.

Two new species of the genus Anatrichis LeConte, 1853 are described from Japan, A. morii, sp. n. (type locality: Fukuoka Prefecture, Shimotoubaru) and A. ryukyuensis, sp. n. (type locality: Okinawa Prefecture, Iriomote Island). Relevant diagnostic features of the new species are described, illustrated and compared with those of other species. A new combination is proposed: Anatrichis infima (Andrewes, 1936), comb. n. from Oodes infimus, and a lectotype designation is made for this species. The “indica” group of species is defined to include all the Asiatic congeners.

AbstractThe number of undescribed species belonging to Mesopolobus s.l. appears to be considerable within the Nearctic region. Quite a few new species were noticed in the collection of the Smithsonian Institution in Washington D.C. None of them appears to belong to species already known in Europe. Some of the already described species, however, could be identical with European MesopoLobus, but any measures regarding their taxonomic position should be deferred until the existing material has been supplemented with fresh specimens.

Two female specimens of the Neotropical genus Ophionthus Bernhauer were found during museum collection surveys, representing different species of the genus. These species are Ophionthus serpentinus Bernhauer, 1908 and O. asenjoi sp. nov. The genus Ophionthus was monotypic until the present study and only known from a single male specimen from Central Peru. The genus is redescribed with the inclusion of female characters from both the type species and the new species here proposed. Additionally, the systematic position of Ophionthus within the Neotropical lineage of Philonthina and its geographical distribution in Peru are reassessed. Descriptions, diagnoses, illustrations, pictures, a cladogram, and a distribution map are provided.
