A new species of paracalanid calanoid copepod Parvocalanus leei sp. n., is described from specimens collected in shallow waters of Western Korea. The new species is closely similar to Parvocalanus arabiensis (Kesarkar & Anil, 2010), Parvocalanus crassirostris (F. Dahl, 1894), Parvocalanus latus Andronov, 1972, and Parvocalanus scotti (Früchtl, 1923) in having two short terminal spines on the distal segment of the fifth leg and a similar rostrum in the female, but can be readily distinguished from its congeners by the body size, relative length of antennules, segmentation of endopod of leg 1, and pattern of ornamentation of spinules on legs 1 to 4 in the female. The taxonomic position of Parvocalanus arabiensis and the validity of the genus Parvocalanus Andronov, 1970 are also discussed.  相似文献

Previous attempts to resolve the Ceratitis FAR complex (Ceratitis fasciventris, Ceratitis anonae, Ceratitis rosa, Diptera, Tephritidae) showed contrasting results and revealed the occurrence of five microsatellite genotypic clusters (A, F1, F2, R1, R2). In this paper we explore the potential of wing morphometrics for the diagnosis of FAR morphospecies and genotypic clusters. We considered a set of 227 specimens previously morphologically identified and genotyped at 16 microsatellite loci. Seventeen wing landmarks and 6 wing band areas were used for morphometric analyses. Permutational multivariate analysis of variance detected significant differences both across morphospecies and genotypic clusters (for both males and females). Unconstrained and constrained ordinations did not properly resolve groups corresponding to morphospecies or genotypic clusters. However, posterior group membership probabilities (PGMPs) of the Discriminant Analysis of Principal Components (DAPC) allowed the consistent identification of a relevant proportion of specimens (but with performances differing across morphospecies and genotypic clusters). This study suggests that wing morphometrics and PGMPs might represent a possible tool for the diagnosis of species within the FAR complex. Here, we propose a tentative diagnostic method and provide a first reference library of morphometric measures that might be used for the identification of additional and unidentified FAR specimens.  相似文献

Exosphaeroma amplicauda (Stimpson, 1857) from the west coast of North America is reviewed and redescribed and revealed to be a group of closely related species. A neotype is designated and the species redescribed based on the neotype and topotypic specimens. Exosphaeroma amplicauda is known only from the coast of California, at Marin, Sonoma and San Mateo Counties. Exosphaeroma aphrodita (Boone, 1923), type locality La Jolla, California and previously considered nomen dubium is taken out of synonymy and re-validated. A further three species: Exosphaeroma paydenae sp. n., Exosphaeroma russellhansoni sp. n., and Exosphaeroma pentcheffi sp. n. are described herein. Sphaeroma octonctum Richardson, 1899 is placed into junior synonymy with Exosphaeroma amplicauda. A key to the Pacific West Coast Exosphaeroma is provided.  相似文献

The genus Eadmuna Schaus, 1928 is revised to include four species. Eadmuna guianensis sp. n., is described from French Guiana and Guyana. The holotype of Perophora pulverula Schaus, 1896, currently placed in Cicinnus Blanchard, 1852, is determined to be a previously unrecognized female Eadmuna, and is transferred accordingly as Eadmuna pulverula comb. n.. Eadmuna paloa Schaus, 1933, rev. status, is removed from synonymy with the type species Eadmuna esperans (Schaus, 1905). Eadmuna esperans, Eadmuna paloa, and Eadmuna pulverula may be of conservation concern due to their limited extent of occurrence and endemicity to the highly imperiled Brazilian Atlantic forest.  相似文献

Among polychaetes, polynoids have the highest number of symbiotic species found living with a wide variety of marine invertebrates, including other polychaetes. Lepidasthenia Malmgren, 1867 and Lepidametria Webster, 1879 were regarded as synonyms but belong to different subfamilies, although both have species associated with thelepodid or terebellid polychaetes. In this contribution Lepidasthenia loboi sp. n. is described from several specimens associated with the thelepodid Thelepus antarcticus Kinberg, 1867, collected on a rocky shore near Puerto Madryn, Argentina. Lepidasthenia loboi sp. n. can be confused with Lepidasthenia esbelta Amaral & Nonato, 1982 because both live with Thelepus, are of similar sizes with similar pigmentation patterns, and have giant neurochaetae. However, in Lepidasthenia loboi sp. n. all eyes are of the same size, cephalic and parapodial cirri are tapered and mucronate, the second pair of elytra is larger than the third, the ventral cirri arise at the base of parapodia such that they do not reach chaetal lobe tips, and neuraciculae are tapered. On the contrary, in Lepidasthenia esbelta the posterior eyes are larger than anterior ones, cephalic and parapodial appendages are swollen subdistally, the second and third pairs of elytra are of the same size, the ventral cirri arise medially such that their tips reach the neurochaetal lobe tips, and the neuraciculae have falcate tips. Some comments about other genera in the Lepidastheniinae, a simplified key to its genera, and a key to Lepidasthenia species with giant neurochaetae are also included.  相似文献

There are four species of Gymnetron in China recorded to date including Gymnetron miyoshii Miyoshi, 1922, Gymnetron villosipenne Roelofs, 1875, Gymnetron auliense Reitter, 1907 and Gymnetron vittipenne Marseul, 1876, of which the last two are new country records. The pre-imaginal stages including eggs, mature larvae and pupae of Gymnetron miyoshii, Gymnetron auliense and Gymnetron vittipenne are described and illustrated. In addition, their diagnostic characters (larvae and pupae) are discussed and differentiated, and notes on some of their biological parameters are provided. Potential ecological impacts between Gymnetron weevils and their host Veronica spp. also are provided.  相似文献

The paper deals with Pheretima multitheca multitheca Chen, 1938 recorded from Vietnam (non Pheretima multitheca Chen, 1938 now in Metaphire from Hainan Island). As a result, a new species, Amynthas erroneous sp. n., is revealed from materials which were previously misidentified as Pheretima multitheca multitheca. The new species is obviously distinguished from other Amynthas species by multiple spermathecal pores lateroventral in intersegments 5/6/7/8/9, and presence of two pairs of crescentic genital markings in xviii. In addition, another new species, Amynthas nhonmontis sp. n., is described and easily recognized by multiple spermathecal pores ventral in intersegments 5/6/7/8 and three pairs of genital markings in xvii, xix and xx.  相似文献

This paper treats 13 species of the subgenus Microdota Mulsant & Rey of Atheta Thomson and 3 species of the genus Clusiota Casey in Canada and Alaska. We report here 4 species new to science, and 3 new provincial records. The following species are new to science: Atheta (Microdota) curtipenis Klimaszewski & Webster, sp. n., Atheta (Microdota) formicaensis Klimaszewski & Webster, sp. n., Atheta (Microdota) macesi Klimaszewski & Webster, sp. n., and Clusiota grandipenis Klimaszewski & Webster, sp. n. The new provincial records are: Atheta (Microdota) pseudosubtilis Klimaszewski & Langor, new to AB, and Atheta (Microdota) subtilis (Scriba), an adventive Palaearctic species new to North America, first reported in LB and NB. The two Clusiota Casey species are reviewed, and their distribution is revised. A female Clusiota impressicollis was discovered in Ontario and is illustrated here for the first time. A key to all Canadian species of the subgenus Microdota and genus Clusiota are provided. Atheta (Microdota) holmbergi Bernhauer and Atheta (Microdota) alesi Klimaszewski & Brunke are transferred here to the subgenus Dimetrota Mulsant & Rey.  相似文献

The taxa of the Lygephila lubrica (Freyer, 1846) species complex are revised. The genital features of all known taxa are described and illustrated, with special reference to the structure of the vesica. Genitalia of Lygephila lubrica from different places in Russia, Central Asia and China are studied, illustrated and compared with different Mongolian populations. Lygephila kazachkaratavika, described as a subspecies, is raised to a species level, stat. n. Neotypes of Lygephila lubrosa (Staudinger, 1901), Lygephila lubrosa kazachkaratavika Stshetkin YuL & Stshetkin YuYu, 1994 [1997] and Lygephila lubrosa orbonaria Stshetkin YuL & Stshetkin YuYu, 1994 [1997] are designated. The female genitalia of the type of Lygephila lupina (Graeser, 1890) is described and illustrated for the first time, and Lygephila mirabilis (Bryk, 1948) treated here as a junior subjective synonym, syn. n.  相似文献

Data on the morphology of the egg, mature larva (L3) and pupa of Squamapion elongatum (Germar, 1817) are presented. The development cycle of this species lasts 51–54 days: a 12-day egg period, a 30-day larval period, and a 12-day pupal period, on average. The larvae are attacked by parasitic hymenopterans of the superfamily Chalcidoidea.  相似文献

The taxonomy of Chamaedrilus glandulosus (Michaelsen, 1888) s. l., most commonly known previously as Cognettia glandulosa, is revised. A recent molecular systematic study has shown that this taxon harbours two cryptic, but genetically well separated lineages, each warranting species status. In this study these two lineages are scrutinized morphologically, on the basis of Michaelsen’s type material as well as newly collected specimens from Central and Northern Europe. Chamaedrilus glandulosus s. s. is redescribed and Chamaedrilus varisetosus sp. n. is recognized as new to science. The two species are morphologically very similar, differing mainly in size, but seem to prefer different habitats, with Chamaedrilus glandulosus being a larger aquatic species, and Chamaedrilus varisetosus being smaller and mainly found in moist to wet soil.  相似文献
