A new species of the calanoid copepod genus Paramisophria T. Scott, 1897 is described from the Egyptian sublittoral zone of the Red Sea. Paramisophria aegypti sp. nov. appears to be closely related to the species Paramisophria ammophila and Paramisophria platysoma. Paramisophria aegypti differs from P. ammophila in having two unequal lateral setae plus one long terminal process and two tiny equal lateral setae plus one long terminal process on the third exopodal segment on the male right and left fifth legs (vs three terminal processes increasing in size inward on both male fifth legs). Paramisophria aegypti can be distinguished from P. platysoma in the following characters: prosome symmetrical (vs extreme asymmetry); third exopod segment of the right leg completely separated from the second segment and bears two unequal lateral setae plus one long terminal process (vs partially fused to the second segment and bears four terminal processes increasing in size inward); third exopod segment of the left leg with two lateral setules and one long terminal process (vs two lateral setules, one short outer medial process and one long terminal process); endopodal lobes of the female legs 5 bear one long plumose seta (vs setae are lacking).http://www.zoobank.org/urn:lsid:zoobank.org:pub:C0A92BF9-2306-4A35-AA39-CE3B5865A396  相似文献

Three new species of rare benthopelagic clausocalanoidean genera with sensory setae on the maxilla are described from female specimens collected during the German Antarctic expeditions ANDEEP I–III in 2002 and 2005, mainly from abyssal depths close to the sea bed. Brodskius abyssalis sp. nov. differs from congeners by the lack of rostral filaments, two setae on the second segment of antenna exopod, thread‐like tips of maxillary worm‐like sensory setae, and the length of spines of P5 exopod. Rythabis assymmetrica sp. nov. is distinguished from other species in the genus by asymmetrical posterior corners of the prosome, the shape of spermathecae, and setal numbers on the maxillulary distal basal endite plus endopod. Omorius curvispinus sp. nov. is characterized by strongly curved setae of the maxillipedal syncoxa, a comparatively long seta on the basis of antenna, a slightly swollen genital double‐somite, and the shape of spermathecae. The genera Brodskius, Omorius, and Rythabis are recorded for the first time from the southern hemisphere.  相似文献

ABSTRACT

In the framework of faunistic research conducted along the Apulian coast of Italy, three new species of thelepodid polychaetes are reported: Streblosoma pseudocomatus sp. nov., S. nogueirai sp. nov. and S. hutchingsae sp. nov. The taxonomic position of S. comatus is clarified and emended as Thelepus comatus. The described species are characterised by their C-shaped arrangement of uncini. The species are compared with their closest congeners and a synoptic table is provided for the species of Streblosma with C-shaped tori.

ABSTRACT

A handful of benthic harpacticoid species are known from the Gulf of California. Here I describe Argestes analongises sp. n. (Argestidae), and Argestigens celibis sp. n. (Ameiridae) from the deep sea of the Tropical Eastern Pacific and Gulf of California. Argestes analongises sp. n. fits in the subfamily Argestinae (Argestidae) and was attributed to the genus Argestes by the presence of small spinules covering the body surface of, at least, the urosome, and by the presence of an extremely elongated distal seta on the sixth segment of the female antennule. This new species seems to be allied to A. angolaensis by the situation of all the caudal setae, and by the ventral position of caudal seta III. They differ in the relative length of the female caudal rami, size, shape and relative position of the sensilla-bearing tubercles associated to the anal somite, armature of the mandibular basis, shape of the exopodal and endopodal segments of swimming legs, and relative length of the setae on the female P5 endopodal lobe and position of the innermost seta of the exopod of the female fifth leg. Argestigens celibis sp. n. was attributed to the family Ameiridae based on the non-argestid maxilla, on the presence of a more or less well-developed endopodal lobe of the male fifth leg and three inner setae on the third endopodal segment of the third leg, and on the presence of the typically modified ameirid-like inner spine on the basis of the male first leg. The new species was attributed to Argestigens based on the non-prehensile endopod of first leg and presence of long inner spinules on the basis of second to fourth legs. Additionally, a new genus, Georgus gen. n., is proposed for Bodinia peterrumi, and some comments are given on the monophyly of that genus.

Intraspecific variation in the pore signature of calanoid copepods is evident between individuals within a single geographical area (within-sample variation) and between different geographical area (geographical variation). Previous studies, however, have tended to consider only geographical variation, neglecting within-sample variation; thus the question remains on how representative the data are of biogeographic divergence within a species. Eight species of the metridinid genus Pleuromamma are examined and the extent of intraspecific variation in pore signatures is assessed here in terms of within-sample variation. In general, the degree of intraspecific variation increases with increasing number of the total integumental pores and is limited to 10% or less of the total. Intraspecific variation reflects not only genetic variability within a species but also genetic similarities between the species within a genus. This paper also re-examines published data on intraspecific variation in pore signatures. Samples as small as five individuals will identify >95% of potential sites of pores.  相似文献

The majority of characters used to separate the nymphs of Ecdyonurus dispar, venosus and torrentis are related to the relative proportions of parts of the body. Extensive measurements suggest that at least certain of these characters are the consequence of heterogonic growth and are not of taxonomic significance. The characters of importance in the taxonomy of the imagines appear to be related either to the effect of the environment during nymphal development on the subsequent pigmentation, limb and body size of the adult, or to the changing spatial relationships between the sclerites of the genitalia during copulatory movements, relationships which are retained when the imago is killed.  相似文献

Twenty‐six marine benthic ciliates including seven new species were isolated from King George Island, Antarctic. The morphology and taxonomy of 19 of them are described in the present paper: Aegyriana paroliva, Amphileptus sp., Amphisiella antarctica nov. spec., Condylostoma cf. magnum, Dysteria parovalis nov. spec., Folliculina ? sp., Hartmannula cf. angustipilosa, Hemigastrostyla szaboi nov. spec., Heterostentor coeruleus, Holosticha sp., Intranstylum antarcticum nov. spec., Metaurostylopsis rubra, Orthodonella shenae, Philasterides cf. armatalis, Pithites pelagicus nov. spec., Pleuronema coronatum, Strombidium apolatum nov. spec., Telotrochidium sp., and Thigmokeronopsis magna nov. spec. Based on the new observations, an improved diagnosis for the genus Aegyriana is suggested: dorsoventrally flattened Dysteriidae with tail‐shaped podite, which is positioned subcaudally in a glabrous region within somatic kineties; oral structure in two parts: ca three close‐set fragments on right and one preoral kinety on left; left postoral kineties shortened posteriorly and continuous with right ones, leaving no median gap or suture; cytopharyngeal rods dominant. According to the new understanding and information obtained, a refined diagnosis of the genus Hemigastrostyla is also suggested: hypotrich with Oxytricha‐like cirral pattern; eight to ten frontal (including one buccal) and five to seven ventral cirri; five transverse and three caudal cirri; no right‐lateral anlagen of dorsal kineties occurring and the old adoral zone will be partly replaced by newly formed structure during morphogenesis; dorsal cilia located in small pits, fibre system highly developed; marine habitat.  相似文献

The paper describes two new species of feather mites collected from the blue-throated blue flycatcher Cyornis rubeculoides (Vigors) (Passeriformes: Muscicapidae) in India (Meghalaya): Trouessartia kharkhanensis Constantinescu et al. sp. nov. (Trouessartiidae) and Proterothrix cyornissimilis Constantinescu et al. sp. nov. (Proctophyllodidae: Pterodectinae). Both sexes of T. kharkhanensis differ from the closest species, T. rubecula Jablonska, 1968 by having setae si and c2 lanceolate and setae c3 and sRIII with acute apex. In males of the new species, the adanal apodemes have a hook-like retroverse apophysis and the internal margins of terminal lamellae have a shallow invagination at the level of setae h3. Both sexes of P. cyornissimilis differ from the closest species, P. cyornis Mironov and Tolstenkov, 2013, mainly by the ornamentation of the dorsal shields: it is absent on the prodorsal shield and poorly expressed on the hysteronothal shield. In males of the new species, the supranal concavity is triangular and the genital arch has a pair of small ovoid sclerites at its tips.
