Morphological classification of loaches (Nemacheilinae)

Comprehensive comparative morphological analysis of loaches from the subfamily Nemacheilinae is conducted. Forty significant phylogenetic characters are suggested, and phylogenetic relationships are reconstructed. The subfamily Nemacheilinae is subdivided into five tribes (Vaillantellini, Lefuini nov., Yunnanilini nov., Triplophysini nov., and Nemacheilini), and the relationships between these tribes can be expressed by the following formula: Vaillantellini (Lefuini (Yunnanilini (Triplophysini + Nemacheilini))). The classification of highland Asian loaches (Triplophysini) is specified, and the revised diagnoses of the genera from this tribe are given. Heterogeneity of the genus Triplophysa is demonstrated. This genus can be divided into several subgenera, and three new subgenera (Labiatophysa subgen. nov., Indotriplophysa subgen. nov., and Tarimichthys subgen. nov.) are described. A new species Hedinichthys grummorum sp. n is described from the Turpan Depression (northwest China).     

Revision and Checklist of the Species (Other Than Lecudina) of the Aseptate Gregarine Family Lecudinidae*

SYNOPSIS. A checklist is given of the 89 named species of the gregarine family Lecudininae, exclusive of the 42 named species of the genus Lecudina (phylum Apicomplexa. class Sporozoea, subclass Gregarinia, order Eugregarinida, suborder Aseptatina). The list includes also the synonyms, host names, locations in hosts, known geographic distributions of the species, as well as key references. Another list is given of synonyms, lapsi calami, nomina nuda, etc., associated with the genera. A new genus, Paraophioidina g. n., with type species, Paraophioidina haeckeli (Mingazzini, 1891) and a new species, Lankesteria ormieresi sp. n., are described. There are also new combinations in the genera Bhatiella, Ancora, Monocystella, Ascocystis, and Paraophioidina.     

Ichneumonids of the subfamily Tanychorinae (Insecta: Hymenoptera: Ichneumonidae) from the Lower Cretaceous of Transbaikalia and Mongolia

A new species, Tanychora loki, sp. nov., and a new genus and species, Megachora sibirica gen. et sp. nov., are described from the Lower Cretaceous of Transbaikalia and Mongolia. The genus Tanychora Townes, 1973 is divided into two genera: Tanychora s. str., composed of T. petiolata Townes, 1973 (type species), T. sinensis Zhang, 1991, and T. loki sp. nov., and Amplicella, gen. nov., composed of A. sessilis (Townes, 1973) (type species), A. exquisite (Zhang et Rasnitsyn, 2003), A. beipiaoensis (Zhang et Rasnitsyn, 2003), and A. spinata (Zhang et Rasnitsyn, 2003). The frequency of occurrence of ichneumonids in the principal Cretaceous localities of central and northern Asia is calculated.     

On the fauna of bristletails of the genera <Emphasis Type="Italic">Petrobius</Emphasis> and <Emphasis Type="Italic">Trigoniophthalmus</Emphasis> (Thysanura,Machilidae) from the Caucasus

Five new species, Petrobius caucasicus sp. n., Trigoniophthalmus presimplex sp. n., T. divnogorski sp. n., T. kislovodski sp. n., and T. adigei sp. n. (Machilidae), are described from the Caucasus. A key to all the known species of the genus Trigoniophthalmus is given. Two subgenera (Trigoniophthalmus s. str., Trigoniocellus subgen. n.) in the genus Trigoniophthalmus are described. 2 + 2 retractile vesicles are present on abdominal segments II–IV in the species of Trigoniocellus subgen. n. and on II–V abdominal segments in Trigoniophthalmus s. str. Analysis of the evolution and phylogenetic relations between the species of the genus Trigoniophthalmus is performed for the first time. The formation of bristletails of the genus Trigoniophthalmus appears to occur in the Caucasian mountain province of the European area, from where they penetrated to the Central European mixed province and the Mediterranean subarea. Among the described species of the genus, T. kislovodski is distinguished by the greatest number of plesiomorphic states of morphological characters.     

A cladistic analysis ofAnisopappus (Asteraceae: Inuleae)

A cladistic analysis of the genusAnisopappus (Asteraceae: Inuleae) has been undertaken. A hypothesis of species interrelationships in the genus is presented for the first time. The analysis also includedArctotis (Arctoteae), used as outgroup, and five additional genera from theInuleae: Geigeria, Calostephane, Asteriscus, Buphthalmum, Pulicaria, andInula. It is concluded thatAnisopappus is a monophyletic group situated at the base of the tribe, diagnosed by, e.g., their obtuse stylar sweeping-hairs. The species with acute sweeping-hairs were found to be derived within the genus. Problems concerning species delimitation, biogeography and character evolution in the genus are briefly discussed.     

A cladistic analysis of Erythracarinae (Acarina: Prostigmata: Anystidae), with the description of a new genus

A cladistic analysis of sixty erythracarine species is presented and used to justify recent nomenclatorial changes to the classification of erythracarine genera. Erythracarinae is redescribed, and a new diagnosis for the subfamily and a key to the included genera are presented. Neotarsolarcus is recognized as a junior synonym of Tarsolarkus, which is recorded for the first time from North America. A new genus, Pedidromus, with six new species (P. agitatus sp.n. P. curiosus sp.n., P. durongensis sp.n., P. peliculus sp.n., P. pilotrix sp.n., P. velox sp.n.) is described.     

Report on the Polycystididae (Rhabdocoela, Kalyptorhynchia) from Australia, with the Description of Twelve New Species and Six New Genera

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.     

The cladistics and biology of the Callajoppa genus-group (Hymenoptera: Ichneumonidae, Ichneumoninae)

A cladistic analysis is presented for the genera of the former ichneumonine tribe Trogini. The tribe Heresiarchini is paraphyletic with respect to the Trogini, and so maintaining Trogini as a separate tribe is unsatisfactory. Within Heresiarchini, the following changes are made: (a) the subtribes Apatetorina and Heresiarchina are referred to as the Apatetor and Heresiarches genus‐groups, (b) the genera of the paraphyletic subtribe Protichneumonina are treated as incerta sedis within Heresiarchini, and (c) the Trogini are referred to as the Callajoppa genus‐group, with the former subtribe Trogina referred to as the Trogus subgroup. Thirty‐five genera are recognized as valid within the Callajoppa genus‐group. Catadelphops, Catadelphus, Cobunus, and Facydes are transferred to this group; Holojoppa is removed and is incertae sedis within Heresiarchini. Three new synonyms are proposed: Araeoscelis and Cryptopyge are junior synonyms of Macrojoppa, and Neamblyjoppa is a junior synonym of Catadelphops. Trogus latipennis Cresson is transferred to Pedinopelte from Macrojoppa, and Trogus mactator Tosquinet and its related species (T. bicolor Radoszkowski, T. heinrichi Uchida, and T. tricephalus Uchida) are transferred to Holcojoppa. Tricyphus is redefined and a neotype is designated for Tricyphus cuspidiger Kriechbaumer, the type‐species of the genus. Thirteen new genera are described (authorship of all is Wahl & Sime): Charmedia (type‐species: Charmedia chavarriai Wahl & Sime, sp. n.) , Daggoo (type‐species: Daggoo philoctetes Wahl & Sime, sp. n.), Dothenia (type‐species: Dothenia hansoni Wahl & Sime, sp. n.), Humbert (type‐species: Humbert humberti Wahl & Sime, sp. n.), Laderrica (type‐species: Laderrica feenyi Wahl & Sime, sp. n.), Mokajoppa (type‐species: Tricyphus respinozai Ward & Gauld), Metallichneumon (type‐species: Metallichneumon neurospastarchus Wahl & Sime, sp. n.), Myocious (type‐species: Myocious orientalis Wahl & Sime, sp. n.) , Quandrus (type‐species: Trogus pepsoides Smith, transferred from Callajoppa), Queequeg (type‐species: Gathetus flavibasalis Uchida, transferred from Neofacydes), Saranaca (type‐species: Trogus elegans Cresson; includes Trogus apicalis Cresson, Tricyphyus ater Hopper, and Tricyphus floridanus Heinrich), Tashtego (type‐species: Tashtego janzeni Wahl & Sime, sp. n.), and Xanthosomnium (type‐species: Xanthosomnium froesei Wahl & Sime, sp. n.). A key to the genera of the Callajoppa genus‐group is provided. The evolution of biological traits within the Callajoppa genus‐group is discussed with reference to the elucidated phylogeny. The groundplan biology is parasitism of Sphingidae, with oviposition into a host pupa/prepupa. There have been two transitions to butterfly parasitism within the Trogus subgroup: one a transition to Papilionidae (followed by a switch to Nymphalidae at Psilomastax) and the other to Nymphalidae (followed by a switch to Papilionidae within Macrojoppa). ©2002 The Linnean Society of London.

Two new taxa of subtribe Rhaconotina (Hymenoptera: Braconidae,Doryctinae, Doryctini) from Africa,with a key to subtribe genera

A new genus, Grangerdoryctes gen. n. (with type species Aivalykus niger Granger), from Madagascar and a new subgenus Pararhacon subgen. n. of the genus Rhaconotus Ruthe (type species R. (P.) haeselbarthi sp. n.) from South Africa are described and illustrated. A discussion of genera without a second radiomedial vein of the fore wing in the tribe Doryctini is presented. The position and content of the subtribe Rhaconotina are discussed and a key for determination of the genera of this subtribe is proposed.     

Phylogenetic systematics of Colotis and associated genera (Lepidoptera: Pieridae): evolutionary and taxonomic implications

We investigated the genetic diversity and phylogenetic placement of the butterflies in the genus Colotis and eight related pierid genera using sequence information from two mitochondrial and two nuclear genes. To establish the status of species, we initially barcoded 632 specimens representative of all genera and most species and subspecies in those genera. A subset was then selected for phylogenetic analysis where additional gene regions were sequenced: 16S rRNA (523 bp), EF‐1α (1126 bp) and wg (404 bp). DNA barcode results were largely congruent with the traditional classification of species in the Colotis group, but deep splits or lack of genetic divergence in some cases supported either species‐level differentiation or synonymy. Despite using information from four genes, the deeper nodes in our phylogeny were not strongly supported, and monophyly of the ‘Colotis group’ and the genera Colotis and Eronia could not be established. To preserve the monophyly of Colotis, we revive the genus Teracolus for three outlying species previously in Colotis (i.e. Colotis eris, Colotis subfasciatus and Colotis agoye), as well as the genus Afrodryas for Eronia leda. The position of Calopieris is unresolved although it appears to be well outside the molecular variation in Colotis (s.l.). A dispersal/vicariance analysis suggested that major diversification in Colotis (s.str.) occurred in Africa with subsequent dispersal to India and Madagascar.     

A phenetic study of Cassia sensu lato (Leguminosae-Caesalpinioideae: Cassieae: Cassiinae) in Thailand

Cassia L. sensu lato, a large heterogeneous genus of flowering plants, occurs naturally in the tropics around the world. Recent works based on floral morphology have supported a division of this genus into three genera, namely Cassia L. s. str., Chamaecrista Moench and Senna Mill. In order to investigate this new classification, 508 specimens of 18 taxa of the genus Cassia s.l. grown in Thailand were analyzed using cluster analysis and canonical discriminant analysis. The total 32 vegetative and reproductive morphological characters were employed in these analyses. In cluster analysis, Cassia s.l. can be separated into four groups, respectively viz. Chamaecrista, Senna alata, Senna and Cassia s /str. The four-cluster grouping is discussed. From a canonical discriminant analysis using the four-cluster grouping as a priori groups, it can be concluded that Cassia s. str., Senna, and Chamaecrista are indeed distinct taxa. The three most important characters that separate the three genera are filament length, fruit length, and ovary stalk length. These quantitative characters, together with some qualitative characters, were useful in constructing an identification key to these genera. Among the three genera, it was also found that Senna is rather a heterogeneous taxon. The difference between the studied species was discussed.     

Three new genera of nematodes (Strongyloidea: Cloacininae) from the redlegged pademelon,Thylogale stigmatica Gould (Marsupialia: Macropodidae) from eastern Australia

Summary Cassunema exigua n.g., n.sp., Monilonema lacunosa n.g., n.sp. and Foliostoma macropodis n.g., n.sp. are described from the stomach of the redlegged pademelon, Thylogale stigmatica Gould, 1860 (Marsupialia: Macropodidae), from north Queensland, Australia. All three genera belong to the subfamily Cloacininae Stossich, 1899 and to the tribe Macropostrongylinea Lichtenfels, 1980. The genus Cassunema is characterized by a poorly sclerotized buccal capsule with longitudinal ridges formed by the lining of the anterior part of the capsule. The genus Monilonema is characterized by a leaf-crown like flange at the mouth opening, a bulbous cervical collar, and paired dorsal and ventral tubular structures running internally and posteriorly from the collar. The genus Foliostoma is characterized by a leaf crown of tiny elements at the mouth opening, and oesophagus with short narrow anterior part, wide posterior part, bulb narrower than corpus and a heavily sclerotized ring between buccal capsule and oesophagus. A revised definition of the tribe Macropostrongylinea is given together with a key to the genera. ac]19810101     

Bartoliella pritchardae n. g., n. sp. (Digenea: Opecoelidae) in Epinephelides armatus (Serranidae) from temperate marine waters of Western Australia

An opecoelid, Bartoliella pritchardae n. g., n. sp., is described from the intestine of Epinephelides armatus from Western Australia. The new genus has been assigned to the subfamily Opecoelininae Gibson & Bray, 1984, bringing the number of genera in the subfamily to two. Although the new genus is similar to Opecoelina Manter, 1934 morphologically, the pedunculate ventral sucker and complete absence of a cirrus-sac necessitate the erection of a new genus. A formal re-definition of the subfamily is given, based on the diagnoses of the genera Opecoelina and Bartoliella n. g.     

Hecabolomorpha n. gen., a new Asian genus from the tribe Hecabolini (Hymenoptera: Braconidae: Doryctinae)

A new Oriental genus Hecabolomorpha n. gen. with the type species H. asiatica n. sp. is described and illustrated from India and Central China. The position of this genus in the tribe Hecabolini and its relations with hecaboline genera are discussed.
