A revised polytomous key for the identification of species of the genusXiphinema Cobb, 1913 (Nematoda: Longidoridae) with exclusion of theX. americanum-group: Supplement 2

Thirty-one species and one subspecies have been described since publication of the first supplement to the polytomous key toXiphinema spp. (see Loof & Luc, 1993). Of these, 11 species belonging to the X. americanum-group are not considered here. Of the 20 remaining species, 13 are considered valid, for which identification codes are given. Three species were described earlier, but had not come to authors' notice; two of them,X. chothecolla andX. clavatus (sic) have already been synonymised withX. radicicola (see Luc & Loof, 1993); codes are given for the third species,X. codiaei. Xiphinema adenohystherum, X. cohni, X. macrogastrum, X. nuragicum andX. sphaerocephalum were considered junior synonyms ofX. pyrenaicum by Baujardet al. (1996);X. hunaniense is considered a junior synonym ofX. radicicola andX. hispanum ofX. aceri. Changes in the group and/or identification codes are made forX. aceri, X. barense, X. dentatum, X. diversicaudatum, X. filicaudatum filicaudatum, X. globosum, X. hardingi, X. paritaliae (= X. dolosum), X. paulistanum, X. pyrenaicum andX. transkeiense. The specific nameX. swarti is emended toX. swartae. Information is given for computerisation of the key.     

A revised polytomous key for the identification of species of the genus Xiphinema Cobb, 1913 (Nematoda: Longidoridae) with exclusion of the X. americanum-group

The species of the genus Xiphinema Cobb, 1913 are listed and their current status is indicated. A revised polytomous key to the 172 valid species (excluding the X. americanum-group) is presented. Because of the very large number of species the key is split into eight groups on the basis of development of the anterior female genital branch, uterine differentiation and tail shape. In accordance with the opinion of Cohn & Sher (1972) X. vulgare Tarjan, 1964 is considered a synonym of X. setariae Luc, 1968. X. cubense Razzhivin, 1973 is placed in species inquirendae. Longidorella chappuisi (Schneider, 1935) is transferred to Xiphinema and its possible identity with X. hygrophilum Southey & Luc, 1974 is discussed.     

New species and new stage descriptions of Campsurus major species group (Polymitarcyidae: Campsurinae), with first report of silk-case construction in mayfly nymphs

Campsurus major, C. argentinus and C. amapaensis sp. nov. form a monophyletic group supported by the following apomorphies in the male genitalia: robust pedestals with a widely rounded inner-posterior margin and a more acute and thinner outer margin, penes strongly sclerotised and curved ventrally, each lobe twisted outwards, and with a small membranous lobe on ventral margin. The nymphs of Campsurus major and C. argentinus and the female adult of C. major are described for the first time and illustrated here; the male adults of both species are redescribed. A new species, C. amapaensis, is described from male imagos. The following new synonymies are proposed: Campsurus argentinus Esben-Petersen (= C. pallidus Needham & Murphy, junior synonym) and C. major Needham & Murphy (= C. brasiliensis Traver, junior synonym). The nymphs of both species are reported to use silk to build soft cases and to glue substrate particles. A list of characters useful to distinguish the treated species from others in the genus is given.     

The Neotropical genera of Acanthocinini Blanchard, 1845 (Coleoptera: Cerambycidae: Lamiinae) with the third antennomere modified

The genera of Acanthocinini which have males with antennomere III modified are discussed and redefined, a key to identify them is provided. Additionally, Alcathousites Gilmour, 1962 is proposed as a junior synonym of Xenocona Gilmour, 1960, and the following five new combinations are proposed: Xenocona asperipennis (Fairmaire & Germain, 1859) n. comb.; X. forsteri (Tippmann, 1960) n. comb.; X. penicillata (Monné, 1990) n. comb.; X. senticosa (Monné & Martins, 1976) n. comb.; and X. superstes (Erichson, 1847) n. comb. Moreover, a new species from Colombia (Huila) is described and illustrated, Xenocona antonkozlovi n. sp., and the male of X. penicillata is illustrated for the first time.     

Two new species of Xiphinema (Nematoda: Dorylaimida) from Colombia

Summary Two new species of Xiphinema are described from Colombia. X. colombiense n.sp. is characterized by a continuous lip region, a median vulva with both genital tracts fully developed and without Z-differentiation, a total stylet length of 197–233 m and a short, rounded tail bearing two pairs of pores and with refractive lines leading through the cuticle to a terminal depression in the protoplasm; it is differentiated from X. clavatum Heyns, 1965, X. guirani Luc & Williams, 1978, X. pyrenaicum Dalmasso, 1969, X. silvaticum Luc & Williams, 1978 and X. yapoense Luc, 1958. X. riocaquetae n.sp. is distinguished from X. macrostylum Esser, 1966. ac]19810707     

Sagum posteli Delamare-Deboutteville & Nunes-Ruivo, 1954 (Copepoda: Siphonostomatoida: Lernanthropidae) parasitic on Epinephelus aeneus (Geoffroy Saint-Hilaire) in Turkish waters, with a key to the species of Sagum Wilson, 1913

Sagum posteli Delamare-Deboutteville & Nunes-Ruivo, 1954 (Copepoda: Lernanthropidae) is reported from the white grouper Epinephelus aeneus Geoffroy Saint-Hilaire caught off the Turkish Mediterranean coast. This documents the first discovery of this species in the Mediterranean and is only the second record. The species is redescribed from adult females and the cephalothoracic limbs are described for the first time. The valid species of the genus Sagum Wilson, 1913 are reviewed, and the poorly described species S. poeyi Ortiz, Lalana & Suarez, 2003 is relegated as a junior synonym of S. texanum Pearse, 1952, described from the same host. A key is provided to females of the ten valid species of Sagum and the known hosts for all species are summarised.     

Some comments on the taxonomy of the species of the genus Neogrubea Dillon & Hargis, 1968 (Monogenea: Mazocraeidae) and their synonyms

The genus Asymmetria Suriano, 1975 is considered a junior synonym of Neogrubea. Similarly, the species A. symmetria Suriano, 1975 is considered to be a junior synonym of N. soni Evdokimova, 1969, and A. platensis Rey & Meneses, 1985 and possibly N. stromateae Gibson, 1976 junior synonyms of N. seriolellae Dillon & Hargis, 1968.     

The Penaincisalia amatista species-group (Lepidoptera: Lycaenidae,Eumaeini) in Colombia,insights from mtDNA barcodes and the description of a new species

A synopsis of the P. amatista species-group in Colombia is provided. Five taxa are considered valid at species level, male and female phenotypes are associated, diagnosed and data on their distribution are given. The geographic variability of the species is discussed, and Penaincisalia celosia new species is described from specimens collected in an isolated branch of the central range in Colombian Andes. We present evidence to consider P. galeraensis (Salazar, Schmidt-Mumm, & Johnson) as a junior synonym of P. albalineata (Johnson). DNA barcodes provided additional information, which was in perfect agreement with the external characters in two of the five species. Interspecific distances were found to range from 0.6% to 6.6% (average 4.3), whilst their mean intraspecific variation ranges from 0.0% to 3.3% (average 0.7%).     

Invalidation of the genus Anomaloporus Voge & Davis, 1953 (Cestoda: Paruterinidae sensu lato)

The type-specimens of Anomaloporus hesperiphonae Voge & Davis, 1953 (type-species of Anomaloporus) from Coccothraustes abeillei (Passeriformes) and A. lambi Voge & Davis, 1953 from Streptoprocne semicollaris (Apodiformes), both from Mexico, are re-examined. The former species is considered a synonym of Orthoskrjabinia conica (Fuhrmann, 1908) (new synonymy) and, consequently, Anomaloporus is regarded as a junior synonym of Orthoskrjabinia Spassky, 1947. The latter species is recognised as valid under the name Anonchotaenia (Anonchotaenia) lambi (Voge & Davis, 1953) n. comb. Orthoskrjabinia rostellata (Rodgers, 1941) and Multiuterina dubininae Mathevossian, 1969, previously believed to be probable synonyms of O. conica, are considered species inquirendae.

Tanytarsus nippogregarius Sasa & Kamimura is a new junior synonym of T. bathophilus. Tanytarsus cultellus Chaudhuri & Datta and T. sibafegeus Sasa et al. are new junior synonyms of T. oscillans.Tanytarsus insulus (Guha et al., 1985) is a new junior synonym of T. ovatus. Tanytarsus sakishimanus Sasa & Hasegawa, T. vinculus Chaudhuri et al., T. parvistylus Chaudhuri & Datta, T. fusciabdominalis Guha et al. and T. euformosanus Kikuchi & Sasa are new junior synonyms of T. formosanus. Tanytarsus tsutaprimus Sasa, T. tokarajekeus Sasa & Suzuki, T. tusimatlemeus Sasa & Suzuki, T. tusimatopeus Sasa & Suzuki and T. yakugeheuus Sasa & Suzuki are new junior synonyms of T. shouautumnalis. Tanytarsus togasiroidus Sasa & Okazawa is a new junior synonym of T. shoudigitatus. Tanytarsus tusimatjekeus Sasa & Suzuki and T. tusimatkeleus Sasa & Suzuki are new junior synonyms of T. akantertius, and Tanytarsus tusimatpequeus Sasa & Suzuki is a new junior synonym of T. tusimatneous. Virgatanytarsus toganiveus (Sasa & Okazawa), Cladotanytarsus utonaiquartus (Sasa) and Zavrelia tusimatijeus (Sasa & Suzuki), all previously placed in Tanytarsus, are new combinations.     

Paralongidorus bullatus n. sp. from Groundnut Soils in Niger and Comments on Xiphinema parasetariae Luc

Paralongidorus bullatus n. sp. from groundnut soils in Sador''é Niger is described and illustrated. It is distinguishable from most species of the genus by its body and odontostyle lengths, knob-like head, and digitate ending of the protoplasmic region of the tail. Length of the female body is 4.4-5.5 mm, of the odontostyle 132-156 μm, and of the tail 32-44 μm. Tail terminus is conoid to broadly rounded. Uteri are well developed, without sperms. Males are not found. Xiphinema parasetariae Luc 1958, a species inquirenda, is validated and, based on measurements and tail structures, X. attorodorum Luc 1961 is proposed as a synonym of X. parasetariae. Additional measurements are given for its females and juveniles.     

Revision of the southern African genus Macroderes Westwood (Coleoptera: Scarabaeidae: Scarabaeinae)

The southern African genus Macroderes Westwood is revised. Six new species, M. amplior n. sp., M. minutus n. sp., M. endroedyi n. sp., M. namakwanus n. sp., M. foveatus n. sp., and M. cornutus n. sp., are described.The neotype of M. bias (Olivier) is designated.Two new synonymies are established: M. pilula Sharp is a junior synonym of M. bias (Olivier), and M. westwoodi Preudhomme de Borre is a junior synonym of M. undulatus Preudhomme de Borre. A key to species and notes on biology and distribution are given.     

The taxonomic history of the family Lecanicephalidae Braun, 1900, a little known group of marine cestodes

Parataenia Linton cannot exist as a cestode genus as it is preoccupied. Discobothrium van Beneden is not a junior synonym of Echeneibothrium van Beneden, and Hornellobothrium Shipley & Hornell and Eniochobothrium Shipley & Hornell are very likely not junior synonyms of Discobothrium. Hexacanalis Perrenoud should be considered a junior synonym of Cephalobothrium Shipley & Hornell. Yogeshwaria Chincholikar & Shinde, Spinocephalum Deshmukh and Flapocephalus Deshmukh are considered unrecognisable. Staurobothrium Shipley & Hornell should be returned to the Phyllobothriidae. Balanobothrium Hornell should remain in the Onchobothriidae Braun. The order Lecanicephalidea was not established by Baylis. There are no grounds for recognising the superfamily Lecanicephaloidea Southwell which contains only the Lecanicephalidae Braun. The elevation of the lecanicephalids to an order, the Lecanicephala, does not appear to be valid. To avoid further confusion the scheme set out by Braun (1900) should be used as a basis for classification of the lecanicephalids.     

An update on the status of native and exotic freshwater fishes of Italy

An updated, corrected checklist of both native and established alien freshwater fish species in Italy is given based on molecular, morphological and biogeographical data. Some 12 native species, reported as conspecific with transalpine species in official Italian ichthylogical literature, are in fact endemics. Previous taxonomic confusion has resulted in the introduction of several alien species, either with official stockings or mixed in as impurities. Rehabilitated species include the cyprinids Scardinius hesperidicus, Scardinius scardafa and Telestes savigny from northern Italy, as well as Squalius ruffoi and the Telestes comes from southern Italy. Squalius albus is a junior synonym of S. squalus. The endemic gudgeon, previously assigned to the genus Romanogobio, is returned to the genus Gobio (G. benacensis). Phoxinus lumaireul is a junior synonym of P. phoxinus. Among the Salmonidae, Salmo cenerinus is a junior synonym of S. marmoratus, while Salmo farioides represents the trout species of the Adriatic lineage for which a neotype is designated. Thymallus aeliani represents the endemic lineage of grayling of the Adriatic populations. The esocid Esox cisalpinus is an endemic pike species and Esox flaviae is a junior synonym; the extensive exportation as well as the presence of this species throughout Europe is possibly due to humans. Among sculpins, Cottus scaturigo and C. ferrugineus are junior synonyms of C. gobio. The International Union for Conservation of Nature (IUCN) categories for native species of Italy are updated. At present, 52 native freshwater fish species are listed: 2 are extinct (Acipenser sturio and Huso huso), 12 are critically endangered, 7 endangered, 10 vulnerable, 3 near‐threatened, 15 low concern and 3 data‐deficient; 35 species are the result of human transfers. Among the 51 introduced species, 6 are recently established (Leuciscus leuciscus, Oreochromis niloticus, Poecilia reticulata, Xiphophorus helleri, Amatitlania nigrofasciatus, Hemichromis sp.), 37 are already established, 5 are probably established and 3 are non‐established Chinese carp, maintained in the wild by intensive stockings. The family most involved is the Cyprinidae, with 22 alien and 20 native species.     

Redescription of Testudotaenia testudo (Magath, 1924) (Eucestoda: Proteocephalidea), a parasite of Apalone spinifera (Le Sueur) (Reptilia: Trionychidae) and Amia calva L. (Pisces: Amiidae) in North America and erection of the Testudotaeniinae n. subfam.

Testudotaenia testudo (Magath, 1924) is redescribed from the intestine of the softshell turtle Apalone spinifera (Le Sueur) (Trionychidae) and the bowfin Amia calva Linnaeus (Amiidae) from Reelfoot Lake, Tennessee, United States. A new subfamily, the Testudotaeniinae, is erected. The new taxon differs from all proteocephalidean subfamilies in the position of the genital organs in relation to the longitudinal internal musculature, i.e. the testes are cortical, rarely medullary; the ovary is partly medullary, with cortical lobes; the vitelline follicles are mainly medullary, with some follicles in the cortex; and the uterus is cortical. A key to the subfamilies of the order Proteocephalidea Mola, 1928 is provided. The most characteristic features of T. testudo are the precocious uterine aperture, the presence of internal uterine pores (as previously described for Proteocephalus paraguayensis (Rudin, 1917)), the eggs laid unripe, the very long strobila (up to 970 mm), and the presence of an anterior circular musculature in the suckers, which is considered as a good differential character. Three other species were found in Amia calva: Proteocephalus perplexus La Rue, 1911, P. ambloplitis (Leidy, 1887) and a new, undescribed form. Sequences of the partial nuclear 28S rRNA gene of specimens of T. testudo from Apalone spinulifera and Amia calva confirm the conspecificity of samples from these two very distinct hosts, which may represent a capture phenomenon. As the subfamily Adenobrechmoinae Bursey, Goldberg & Kraus, 2006 and the genus Adenobrechmos Bursey, Goldberg & Kraus, 2006 are based on the presence of an apical organ, a character which reflects a rather common convergence, we consider the Adenobrechmoinae to be a junior synonym of the Proteocephalinae La Rue, 1911 and Adenobrechmos a junior synonym of Ophiotaenia La Rue, 1911. Adenobrechmos greeri Bursey, Goldberg & Kraus, 2006 thus becomes Ophiotaenia greeri (Bursey, Goldberg & Kraus, 2006) n. comb.     

Redescription, generic allocation and synonymy of Decorataria magnilabiata (Molin, 1860) n. comb. (Nematoda: Spirurida: Acuariidae), a parasite of the roseate spoonbill Platalea ajaja L. (Aves: Threskiornithidae) in South America

Decorataria magnilabiata (Molin, 1860) n. comb. is proposed for Dispharagus magnilabiatus Molin, 1860 [= Acuaria (Cheilospirura) magnilabiata (Molin, 1860) Railliet, Henry & Sisoff, 1912; Cheilospirura magnilabiata (Molin, 1860) Stiles & Hassall, 1920; Dispharynx magnilabiata (Molin, 1860) Gendre, 1920] (Nematoda, Spirurida, Acuariidae), a parasite of the roseate spoonbill Platalea ajaja L. (Ciconiiformes, Threskiornithidae) known from Brazil, France (bird in captivity), Argentina and Cuba. The species is redescribed and illustrated on the basis of the type-series (from Brazil) in the Helminthological Collection of the Naturhistorisches Museum, Vienna. Syncuaria diacantha Petter, 1961 [= Decorataria diacantha (P.) Skryabin, Sobolev & Ivashkin, 1965], originally described from Platalea ajaja in France (bird in captivity), is recognised as a junior synonym of Decorataria magnilabiata (new synonymy).     

Xiphinema bacaniboia n.sp. (Nematoda: Dorylaimida) from Fiji

Summary Xiphinema bacaniboia n.sp. is described from rain forest in Fiji. Adult females are characterized by their spiral shape on heat death, slightly offset lip region, total stylet length of 270–292 m, post-median vulva, paired, opposed genital branches with greater development of the anterior one, absence of a Z organ and the presence of a broadly rounded tail, flattened ventrally with no blind canal. The species is differentiated from X. ingens Luc & Dalmasso, 1964, X. macrostylum Esser, 1966 and X. riocaquetae Hunt, 1982. ac]19830610     

Microcotyle visa n. sp. (Monogenea: Microcotylidae), a gill parasite of Pagrus caeruleostictus (Valenciennes) (Teleostei: Sparidae) off the Algerian coast,Western Mediterranean

Parasite biodiversity of fish of the southern part of the Mediterranean sea is still incompletely explored. We describe here Microcotyle visa n. sp. from the gill filaments of the bluespotted seabream Pagrus caeruleostictus (Valenciennes) (Sparidae) collected off the Algerian coast. The identity of fish hosts was confirmed by barcoding. Microcotyle visa n. sp. is herein described and illustrated. Analysis of the cox1 gene of the monogeneans revealed minor intraspecific variation (1.4%), an order of magnitude lower than the distance between this species and other Microcotyle species (10–15 %). Microcotyle visa n. sp. is distinguished from Microcotyle erythrini van Beneden & Hesse, 1863, a congener infesting sparids, on the basis of morphological (size of clamps, number of testes) and molecular (cox1) differences. This is the fourth member of the genus known to parasitise a sparid host. A species of Paramicrocotyle sp. included in the molecular analysis was nested within a robust Microcotyle + Paramicrocotyle clade; in the absence of demonstrated molecular and morphological differences, we consider that Paramicrocotyle Caballero & Bravo-Hollis, 1972 is a junior synonym of Microcotyle van Beneden & Hesse, 1863 and transfer two species of Paramicrocotyle as Microcotyle danielcarrioni (Martinez & Barrantes, 1977) n. comb. and Microcotyle moyanoi (Villalba & Fernandes, 1986) n. comb.

     

Rotifera from Burundi: the Lepadellidae (Rotifera: Monogononta)

We studied the distribution of Lepadellidae (Rotifera) in freshwater habitats in the floodplain of the River Rusizi in northwest Burundi. Twenty-three species belonging to ColurellaBory de St. Vincent, 1824 (3 species), Lepadella Bory de St. Vincent, 1826 (18 species) and Squatinella Bory de St. Vincent, 1826 (2 species) are recorded, 22 of them are new to Burundi. One of the taxa encountered probably represents an unnamed species. Lepadella arabicaSegers & Dumont, 1993 is recognised as junior subjective synonym of Lepadella eurysterna Myers, 1942 (syn. nov.). Most of the taxa recorded are cosmopolitan or tropicopolitan, two are restricted to the tropical regions of the Old World and Australia, and one, Squatinella lunata Segers, 1993 is an Ethiopian endemic.
