Parasitic Isopod

The parasitic isopod family Cymothoidae Leach, 1818 of the India exclusive economic zone is reviewed. A total of 56 nominal species corresponding to 48 valid species belonging to sixteen genera are reviewed from 73 host species belonging to 35 families. Mothocya plagulophora (Haller, 1880), Nerocila depressa Milne Edwards, 1840, Nerocila loveni Bovallius, 1887, Nerocila trichiura (Miers, 1877), Norileca triangulata (Richardson, 1910) and Ryukyua globosa Williams & Bunkley-Williams, 1994 are redescribed. Indusa pustulosa Pillai, 1954 is synonymised with Agarna malayi Tiwari, 1952; Cymothoa krishnai Jayadev Babu & Sanjeeva Raj, 1984 is synonymised with Cymothoa eremita (Brünnich, 1783) and Nerocila priacanthusi Kumari, Rao & Shyamasundari, 1987 is synonymised with Nerocila arres Bowman & Tareen, 1983. Ourozeuktes bopyroides (Lesueur, 1814) is revised and excluded from the Indian fauna. The Indian cymothoid species Agarna bengalensis Kumari, Rao & Shaymasundari, 1990, Cymothoa asymmetrica Pillai, 1954 and Nerocila hemirhamphusi Shyamasundari, Rao & Kumari, 1990 are regarded here as species inquirenda. A key to the Indian genera of the family Cymothoidae and keys to the Indian species of the genera Cymothoa, Joryma, Mothocya, and Nerocila are presented. A checklist of the valid Cymothoidae species until now reported from Indian marine fishes are compiled. Host preferences, morphological variability and distribution are discussed.

A taxonomic review of the cosmopolitan genus Filellum was performed considering morphology, morphometry and cnidome. Species for which we had access to materials were redescribed and morphologically characterized based on optical and scanning electron microscopy (SEM). The materials examined belong to museum collections, including type specimens. All records found in the literature were checked. Our analyses confirmed the validity of 10 out of the 18 nominal species referred to the genus, and established four others (F. adnatum, F. bouvieri, F. contortum and F. plicatum) as species inquirenda. A new species, Filellum bouvetensis sp. nov., is described. The species Reticularia annulata Watson, 1973, type species of the genus Corystolona Watson, 2002, has its type specimen referred to the genus Filellum, composing Filellum annulatum (Watson, 1973). We provide a key for the identification of the valid species of the genus Filellum.

Type Population

Summary The type population of Meloidogyne polycephannulata is synonymised with M. incognita based on morphological and morphometric characters, as well as biochemical, molecular and phylogenetic studies. Morphological variability and a wide host range were reported for M. incognita during its first description and later re-description. Meloidogyne polycephannulata was described in Brazil from specimens collected in a carrot field (type population). The esterase phenotype (Est) characterised for this species was identical to the phenotype Est I2 of M. incognita, the most ubiquitous phenotype used for diagnostics. Morphological and morphometric characters of the descriptions of the two nominal species showed major similarities, as well as variability within the range of variation detected in M. incognita. In PCR assays, three SCAR markers species-specific for M. incognita (incK14 F/R, Mi/FR and incB06 F/R) amplified the same fragments of 399 bp, 955 bp and 1200 bp, respectively, for populations in both species. In phylogenetic studies based either on concatenated sequences of ITS1-5.8S-ITS2, D2-D3 rRNA, mitochondrial COII regions or on RAPD and AFLP data, the populations of both species grouped in the same clade with high bootstrap support. Altogether, these results provide congruent evidence that the M. polycephannulata type isolate deposited at the Embrapa Cryopreserved National Collection of Root-knot Nematodes is not a valid species but rather a junior synonym of M. incognita.

Psammoperca Waigiensis

Psammoperca datnioides Richardson 1848, long considered a synonym of P. waigiensis (Cuvier in Cuvier & Valenciennes 1828), is redescribed as a valid species of Psammoperca Richardson 1848. The species is likely to be endemic to Australia, where it was formerly considered to be P. waigiensis, but differs from P. waigiensis in having the following characters: more slender body (mean depth 28.9% of SL vs. mean depth 36.7% of SL in P.  waigiensis), pored lateral-line scales 49–54 (vs. 46–48 in P. waigiensis), scale rows above and below lateral line 6½ / 10½–11½ (vs 4½ / 9½–10½ in P. waigiensis), and vertical at hind margin of maxilla posterior/behind center of eye (vs. vertical at hind margin of maxilla anterior to/in front of hind margin of eye in P. waigiensis). Live specimens of Psammoperca datnioides have a uniformly dense black or brownish body, with this dark colour on body scales and pored lateral-line scales persisting even in preserved specimens. Live specimens of Psammoperca waigiensis have a brownish body, often golden in colour, and pored lateral-line scales that are yellow-edged. The COI sequence (cytochrome c oxidase subunit I, 612 bp) of P. datnioides also is distinct from P. waigiensis, and the related and poorly known Hypopterus macropterus (Günther 1859). The latter species is redescribed and diagnosed with eight indistinct dark bands on the head and body, and dorsal-fin rays VII-I, 14–15 (vs. no dark bands and dorsal-fin rays VII-I, 12–13 in Psammoperca). Nominal species in the genus Psammoperca are discussed and Cnidon chinensis Müller & Troschel 1849 (type locality: Manila, Philippines) is included as a junior synonym of P. waigiensis. Psammoperca vaigiensis Boulenger 1895 is an unneeded emendation and thus an invalid name. Psammoperca macroptera Günther 1859 is retained in the monotypic genus Hypopterus Gill 1861 in the family Latidae, although the species has been overlooked in most studies on the Latidae and/or Centropomidae. A key to the Latidae is provided.

The paper presents the first world catalogue of the millipede order Callipodida (Diplopoda: Helminthomorpha). The order is currently known to comprise 3 suborders, 7 families, 35 valid (sub-)genera and 133 (sub-)species. Furthermore, 10 nominal species, whose taxonomic status has not been considered in any publications other than the first descriptions, are listed as species inquirenda. The synonymy of Paracortina wangi Stoev, 2004 under Angulifemur unidigitis Zhang, 1997 is formalized here. Given for each (sub-)species are the original description with author, year, pages and figures; complete chronological list of subsequent faunistic or taxonomic references; type material and, if known, current repository; type locality; species range; and sometimes additional remarks on its status or distribution. The relevant taxonomic and faunistic literature on Diplopoda was consulted to complete the data presented here. The species list is based on a species index card catalogue housed in the Museum National d’Histoire Naturelle in Paris (“Fichier iconographiqueBrolemann et successeurs”), with additions from the Zoological Record and various on-line resources. A bibliography containing 286 taxonomic references relevant to the Callipodida is included.

Species Inquirendae

Species of the genus Sadocus Sørensen, 1886 are conspicuous gonyleptids that occur in Chile and Argentina. Here, the genus is revised for the first time and the cladistic analysis based on morphological characters does not corroborate its monophyly unless a phylogenetically unrelated species is excluded (explained further on). A new classification is proposed for the seven species left in the genus and considered valid, of the 13 nominal species previously recognized. Two out of the seven valid species are considered as species inquirendae: Sadocus allermayeri (Mello-Leitão, 1945) [= Carampangue allermayeri Mello-Leitão, 1945] and Sadocus nigronotatus (Mello-Leitão, 1943) [= Carampangue nigronotatum Mello-Leitão, 1943]. The following synonymies are proposed: Sadocus bicornis (Gervais, 1849) [original combination = Gonyleptes bicornis Gervais, 1849] is a junior synonym of Sadocus asperatus (Gervais, 1847) [= Gonyleptes asperatus Gervais, 1847]; Sadocus conspicillatus Roewer, 1913, Sadocus exceptionalis (Mello-Leitão, 1946) [= Araucanoleptes exceptionalis Mello-Leitão, 1946] and Sadocus guttatus Sørensen, 1902 are junior synonyms of the valid name Sadocus polyacanthus (Gervais, 1847) [= Gonyleptes polyacanthus Gervais, 1847]; and Sadocus calcar (Roewer, 1913) [= Lycomedes calcar Roewer, 1913] is a junior synonym of the valid name Gonyleptes horridus Kirby, 1819. Sadocus brasiliensis Soares & Soares, 1949 is not congeneric with Argentinean/Chilean species of the genus according to the cladistic analysis and is here synonymized with Discocyrtus catharinensis (Mello-Leitão, 1923 [= Sadocus catharinensis Mello-Leitão, 1923]).

First Time

The family Echiniscidae comprises limno-terrestrial heterotardigrades with a strongly sclerotised dorsum, typically covered with plates. Among other members of the Echiniscus evolutionary line, the genus Testechiniscus Kristensen, 1987 stands out with well-developed ventral armature and polygonal sculpturing of the dorsal plates. It has alleged bipolar distribution (with satellite alpine records in the Holarctic). Thanks to fresh material from terra typica (Svalbard), we integratively redescribe (i.e. using light and electron microscopy imaging, morphometry, and molecular methods) the nominal species for the genus, Testechiniscus spitsbergensis (Scourfield, 1897). A comparison of the neotype series with a number of Holarctic records revealed morphological variability suggesting that the species may encompass several taxa, which, most likely, will be possible to delineate primarily with molecular tools. Moreover, based on material from Simien Mountains (Northern Ethiopia), we describe a new sibling subspecies, Testechiniscus spitsbergensis tropicalis ssp. nov. Extensive morphometric datasets are provided for the genus members for the first time. A new generic definition is proposed, embracing the two subspecies of T. spitsbergensis and T. laterculus (Schuster et al., 1980), but excluding two circum-Antarctic species, T. macronyx (Richters, 1907) and T. meridionalis (Murray, 1906). The later species are likely to be erected in the future as separate genera, and their autapomorphies are described here. In the light of our findings, the genus          Testechiniscus should be recognised as a native element of the Northern Hemisphere, with mainly circum-Arctic distribution and additional, insular alpine records from the Nearctic, Palearctic and Eastern Afrotropic.

A New Species

Teugels et al. (1991) considered the genus Auchenoglanis to be comprised of two valid species: A. biscutatus and A. occidentalis. A new analysis of all the nominal species and subspecies of the genus supports the recognition of all nominal taxa as species. Each species is diagnosed primarily on mensural characters, size and shape of the premaxillary tooth patches, and pigmentation patterns. In addition, a new species, Auchenoglanis senegali, is described from Senegal.

The genus name Centruroides was first introduced by George Marx (in Howard, 1889: 211) for two species of scorpions in the family Buthidae: C. exilicauda (Wood, 1863) and C. luctifer n. sp. The latter species, coming from Indefatigable Is. (Galapagos), lacks a description and has been considered as a nomen nudum and synonym of Centruroides exsul (Meise, 1934) (Lambertz, 2013). Nonetheless, exilicauda Wood (Buthus) is an available and valid species name; thus, Centruroides is available according to the ICZN, 1999, Art. 12.2.5. (“the specific name or names can be unambiguously assigned to a nominal species-group taxon or taxa”).

Omalaspis Giraud, 1860, is a genus of Aspicerinae (Hymenoptera: Cynipoidea: Figitidae) with a Holarctic distribution. The diagnostic characters that differentiate Omalaspis from morphologically similar genera are described. From the thirteen known species of Omalaspis only O. cavroi (Hedicke, 1914), O. latreillii (Hartig, 1840), O. norica Giraud, 1860 and O. orientalis Belizin, 1968 are valid species. All these species are redescribed. Omalaspis nigra (Hartig, 1840) and O. abnormis (Kieffer, 1901) are synonymized with O. norica, and O. ruficornis Thomson, 1877 is synonymized with O. latreilli. Omalaspis laevis Hedicke, 1914 belongs to Xyalaspis, O. davydovi Belizin, 1927 is considered as ‘incertae sedis’ and O. carinata (Kieffer 1901) ‘species dubia’. Three species are considered as species inquirenda: Omalaspis femoralis Ionescu, 1963 (which belongs to Diapriidae), O. convexa Kierych, 1985 and O. sulcata (Kieffer, 1901). Six new species are described: O. asiatica Ros-Farré & Pujade-Villar n. sp., O. brandaoi Pujade-Villar & Ros-Farré n. sp., O. curvilineata Ros-Farré & Pujade-Villar n. sp., O. gibsoni Ros-Farré & Pujade-Villar n. sp., O. niponica Ros-Farré & Pujade-Villar n. sp. and O. villemantae Pujade-Villar & Ros-Farré n. sp. The diagnostic characters of all species are illustrated and a key to differentiate them is given. A new character is defined here exclusive to Omalaspis within the Aspicerinae, the supratorular impression.

Published and unpublished data on the epigeic and cave centipedes of Sardinia (Italy) are summarized and critically revised in this paper. Fifty-four species are listed and discussed (1 Scutigeromorpha, 19 Lithobiomorpha, 6 Scolopendromorpha, 28 Geophilomorpha), two of which new to the island: Lamyctes emarginatus (Newport, 1844) and Schendyla montana (Attems, 1895). Thirty-one species have been recorded in caves (1 Scutigeromorpha, 14 Lithobiomorpha, 6 Scolopendromorpha, 10 Geophilomorpha) – including the poorly known Plutonium zwierleini Cavanna, 1881 – six of which exclusive of this habitat (5 Lithobius spp., 1 Cryptops sp.). Five species are introduced or probably introduced. General geographic distribution, chorotype, Sardinian localities and ecological notes (altitudinal ranges, habitats) are given for each species. Taxonomic notes are given for some species. Lithobius turritanus Fanzago, 1881 and Lithobius molophai Restivo De Miranda, 1978, previously considered synonyms of Lithobius tricuspis Meinert, 1872 and Lithobius cerii Verhoeff, 1943, respectively, are recognized as valid species, status rev. The new synonymies Lithobius melanops domusnovae Restivo De Miranda, 1976 = Lithobius lapidicola Meinert, 1872 syn. nov., Lithobius oligoporus Latzel, 1884 = Lithobius turritanus Fanzago, 1881 syn. nov. and Lithobius fraleliae De Miranda Restivo, 1978 = Lithobius turritanus Fanzago, 1881 syn. nov. are proposed. Lithobius turritanei Restivo De Miranda i. l. in Cassola, 1982 is recognized as nomen nudum. Cryptops breviunguis A. Costa, 1882 is proposed as species inquirenda and its identity with Cryptops anomalans Newport, 1844 is rejected. Lithobius molophai Restivo De Miranda, 1978 and L. sardous Silvestri, 1898 are redescribed on type or topotypical material. A lectotype for L. sardous Silvestri, 1898 is also designated. Lithobius sardus Manfredi, 1956 status nov., formerly a subspecies of L. agilis C. L. Koch, 1847, is raised to species level; its probable affinity with L. turritanus Fanzago, 1881 is also discussed. Lithobius infossusSilvestri, 1894 (= L. dahlii Verhoeff, 1925) is erased from the centipede fauna of Sardinia, and previous records should be referred to an unidentified species of Lithobius or to L. nuragicus Zapparoli, 1997.
