The examination of gill parasites from èSarotherodon occidentalisè (Daget) (Pisces, Cichlidae) in Guinea and Sierra Leone (West Africa) revealed the presence of seven species of Monogenea. Two of them have previously been described: ichlidogyrus halli; (Price & Kirk, 1967) and Scutogyrus ecoutini Pariselle & Euzet, 1995. Five are considered as new species, all belonging to Cichlidogyrus Paperna, 1960. They are C. bouvii n. sp., C. fontanai n. sp., C. guirali n. sp., C. paganoi n. sp. and C. sanjeani n. sp.Résumé L'examen des parasites branchiaux de Sarotherodon occidentalis (Daget) (Pisces, Cichlidae) en Guinée et en Sierra Leone (Afrique de l'Ouest) a révélé la présence de sept espèces de Monogènes.

Three new cyrtophorian ciliates isolated from coastal areas of China were described based on morphological and genetic data. The Chlamydodon mnemosyne‐like species Chlamydodon similis sp. n. differs from its congeners mainly by its number of somatic kineties. Chlamydodon oligochaetus sp. n. is distinguished from its congeners mainly by having fewer somatic kineties, and/or an elongated body shape. Chlamydodon crassidens sp. n. is characterized mainly by an inverted triangular body shape, a posteriorly interrupted cross‐striated band (5–6 μm wide), and a large cytostome. Moreover, we provided small‐subunit (SSU) rDNA sequences of C. similis sp. n. and C. oligochaetus sp. n. Maximum likelihood (ML) and Bayesian inference (BI) consistently placed C. similis sp. n. as a sister to C. paramnemosyne, but showed different branching position of C. oligochaetus sp. n., which may be due to a low taxon sampling in the Chlamydodontidae and/or an insufficient resolution of the marker gene at species level.  相似文献

Twelve new species of Chauhanellus Bychowsky & Nagibina, 1969 have been found on six species of ariid from Peninsular Malaysia: Chauhanellus trifidus n. sp., C. digitalis n. sp., C. malayanus n. sp., C. forcipis n. sp. and C. intermedius n. sp. from Arius sagor; C. aspinous n. sp. from Arius venosus; C. caelatus n. sp. from Arius caelatus; C. auriculatum n. sp., C. poculus n. sp. and C. pulutanus n. sp. from Arius maculatus; C. duriensis n. sp. from Arius thalassinus; and C. osteogeneiosi n. sp. from Osteogeneiosus militaris. Some of these Chauhanellus species possess characteristics that are not commonly observed in the genus. C. aspinous n. sp., C. intermedius n. sp. and C. digitalis n. sp. exhibit features found in both Chauhanellus and Hamatopeduncularia: these include absence of spines on the mainpart of the dorsal anchors in C. aspinous n. sp. and C. intermedius n. sp. and presence of haptoral digitation in C. digitalis n. sp. Other features are the five transverse rows of peduncular spines in C. duriensis n. sp., ear-like projections on the anchors in C. auriculatum n. sp., and thin sclerotised plates that partly envelope the ventral anchors in C. forcipis n. sp. Mid-dorsal appendices occur on the dorsal bars of seven of the present species.  相似文献

A survey of 79 fish species revealed 16 species of Colobomatus of which 11 are new and described below. The first ten new species were from Australian fish and the eleventh from a South African fish.The following species are described: Colobomatus cresseyi n. sp. from the eastern river garfish Hyporhamphus regularis ardelio (Whitley) and the snub-nosed garfish Arrhamphus sclerolepis krefftii (Stein-dachner); C. nanus n. sp. from the trumpeter Pelates quadrilineatus (Bloch); C. lesteri n. sp. from the common silver-belly Gerres ovatus (Günther); C. sewelli n. sp. from the seven-fingers tassel-fish Polynemus heptadactylus Cuvier; C. hispidus n. sp. from the blotched javelin-fish Pomadasys maculatus (Bloch); C. ornatus n. sp. from the whiptail Pentapodus setosus (Cuvier & Valenciennes); C. cribbi n. sp. from the barred-faced spine-cheek Scolopsis taeniopterus (Kuhl & van Hasselt); C. rothae n. sp. from the dusky flathead Platycephalus fuscus (Cuvier & Valenciennes) and the bar-tailed flathead P. indicus (L.); C. gietzelae n. sp. from the thread-fin silver-belly Gerres punctatus (Cuvier & Valenciennes); C. creeveyae n. sp. from the white trevally Pseudocarynx dentex (Bloch & Schneider); and C. mackayi n. sp. from an African haemulid, Pomadasys striatus (Gilchrist & Thompson). Colobomatus mylionus Fukui, 1965, is redescribed from the silver bream Acanthopagrus australis (Günther).Details of the mouthparts of C. kyphosus Sekerak, 1970, are given for the first time. This is a relatively plesiomorphic member of the genus (West, unpublished data), and its morphology assists in the interpretation of the appendages of the Australian species.Revised diagnoses for the family Philichthyidae Vogt and the genus Colobomatus hesse, 1873 are given. These incorporate the genus Colobomatoides Essafi & Raibaut, 1980 and the new Colobomatus species described herein respectively.  相似文献

Microula pentagona W. T. Yu, S. T. Chen & Z. K. Zhou sp. nov. and M. galactantha W. T. Yu, S. T. Chen & Z. K. Zhou sp. nov. (Boraginaceae) from the eastern Qinghai‐Tibetan Plateau are described and illustrated. Microula pentagona is characterized by the pentagonal dark purple pubescent corolla throat, whereas M. galactantha is distinct by its white flowers and a nutlet attachment near the apex. The diagnostic features of the two new species are compared with other species of the genus.  相似文献

A complex of about 40 Palaearctic species of the genus Campodorus with long haired ovipositor sheath and with entirely rufous or white-banded hind tibia is considered and keyed. Twenty-one new species are described. The species with the pale rufous hind tibia have black hind coxa and trochanters, most of them also have rather long genae and scabrous mesopleura. The majority of these species are distributed in subarctic Siberia: C. yakutator sp. n., C. minutor sp. n., C. arctor sp. n., C. atripes sp. n., C. pequenitor sp. n., C. mordax sp. n., C. lucidator sp. n., C. subarctor sp. n., C. nikandrovskii sp. n., and C. genator sp. n. C. suomi sp. n. is described from northern Finland, C. labytnangi sp. n., from Kola Peninsula, the Polar Ural, and Transbaikalia, and only C. gallicator sp. n., from France (? Alps). The species with a white band on the hind tibia are mostly boreal; most of them have red coxae and trochanters (except for C. sakhalinator sp. n. and C. taigator sp. n.), rather short genae, and granulate mesopleura. In this group, eight new species are described: C. atrofemorator sp. n., C. barbator sp. n., C. sakhalinator sp. n. (all from the southern part of the Russian Far East), C. taigator sp. n. (southern Siberian), C. ciliator sp. n., C. melanopygus sp. n., C. marginator sp. n., and C. boreator sp. n. (European-Siberian).  相似文献
