Identification keys to the subfamilies of the Corioxenidae, the genera of the subfamily Uniclavinae, and the species of the genus Dundoxenos are provided. A list of all described species of Corioxenidae is given, including information on geographic distribution, and host species when available.     

New genera and new species of leaf beetles (Coleoptera: Polyphaga: Chrysomelidae) from Lowermost Eocene French amber

Three new monotypical genera of leaf beetles are described: Aoriopsis eocenicus n. gen, n. sp. and Acolaspoides longipes n. gen., n. sp. from the subfamily Eumolpinae, and also Crepidocnema yantarica n. gen., n. sp. from the subfamily Alticinae. Short reviews of known fossil records of the mentioned subfamilies are given and position of the new genera discussed.     

Two new non-biting midges from the Early Cretaceous Lebanese amber (Diptera: Chironomidae)

Abstract

Two chironomid flies, Ziadeus kamili n. gen., n. sp. and Paicheleria magnifica n. gen., n. sp., respectively attributed to the recent subfamilies Tanypodinae and Prodiamesinae, are described from the Early Cretaceous Lebanese amber. Although very old, this non-biting midge fauna was very diverse with no less than 11 genera and species. However, it was also strongly different from the recent faunas for the complete absence of the Chironominae, that is today the dominant subfamily. The development of the modern chironomid fauna occurred during the Late Cretaceous and/or the Early Paleogene, but when and how?     

Itaquascon unguiculum and Itaquascon cambewarrense. two new species of eutardigrades from Australia

Abstract

Two new species of eutardigrade, Itaquascon unguiculum and Itaquascon cambe‐warrense, are described from Australia. Itaquascon unguiculum differs from the other species of the genus by having small claws with respect to the body size, and in other quantitative characters. Itaquascon cambewarrense is characterised by stylet furcae which are triangular in shape, with apices thickened but not prolonged to form postero‐lateral processes.     

Review of the cicada genus Karenia (Hemiptera: Cicadidae), with a description of one new species trapped by clapping hands and its entomogenous fungus

Abstract

The Oriental cicadas of the genus Karenia are reviewed and a key to the species is presented. One new species, K. chama Wei & Zhang, sp. nov., trapped by hand clapping and bamboo‐stick clicking, is described and illustrated. Information on its biology, as well as a few notes on its special sound‐production mechanism, is provided in some detail. The sound communication and mimicry of attracting cicadas, the associated cicada fungus, Elaphocordyceps sp., and the distribution of Karenia species are discussed.     

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 New Zealand genus Metablax (Coleoptera: Elateridae) and its relationship to the Campsosterninae

The genus Metablax is endemic to New Zealand. The fauna falls into 2 distinct species‐groups, here designated the acutipennis‐group (acutipennis, brouni) and the approximans‐group (approximans, gourlayi n.sp., cinctiger). All taxa are described and illustrated, and a key is given for their separation. A typical Metablax larva is described and illustrated. The systematic position of the genus is discussed in relation to the Neotropical Campsosterninae, and on the basis of both adult and larval characters Metablax is here assigned to subfamily Campsosterninae.     

Identity and biological race of a population of potato cyst nematode from Pukekohe,New Zealand

A population of potato cyst nematode recently discovered at Pukekohe, New Zealand, is identified as Heterodera pallida Stone, 1972. Diagnostic characters of the larvae—total length, width of the lip region, length of the stylet, length and width of the stylet knobs, and distance of the genital primordium from the anterior end—exclude the population from H. rostochiensis. Tested against differentially resistant clones of Solanum spp., the population appeared to be identical to biological race Dutch D.     

Notes on some tardigrades from Thailand,with descriptions of two new species

Abstract

Three species of tardigrades are reported from Thailand: Pseudechiniscus quadrilobatus Iharos, 1969, Calcarobiotus (Calcarobiotus) digeronimoi sp. n., and Mixibius sutirae sp. n. Calcarobiotus (C.) digeronimoi sp. n. has claws of Calcarobiotus type; those of the first three pairs of legs have a medial and a lateral spur, those of the hind legs lack basal spurs. Mixibius sutirae sp. n. has a densely sculptured dorsal cuticle and two macroplacoids; it lacks lunules and other thickenings on the legs. It is similar to Mixibius ornatus Pilato et al., 2001, from which it differs in characteristics of the cu‐ticular sculpture and by having the ventral surface unsculptured.     

A new viviparous acoel Childia vivipara sp. nov. with observations on the developing embryos, sperm ultrastructure, body wall and stylet musculatures

A free‐living viviparous acoel, Childia vivipara sp. nov., from the Gullmar fjord of the Swedish coast is described. The new species is assigned to the taxon Childia based on histological, ultrastructural and molecular sequence similarities. All available molecular markers (18S rRNA, 28S rRNA and histone H3) and several morphological characters, obtained using transmission electron microscopy and confocal scanning laser microscopy of whole mount specimen stained with TRITC‐labelled phalloidin, support the placement of C. vivipara in the taxon Childia. Childia vivipara and other Childia species share the following morphological synapomorphies: well‐developed copulatory organs built of tightly packed stylet needles, proximal part of the stylet inserted into the seminal vesicle, reversed body‐wall musculature, absence of ventral diagonal muscles, presence of dorsal diagonal muscles, and presence of ventral straight longitudinal muscles between frontal pore and mouth, 9 + 1 sperm axoneme structure, six distal sperm cytoplasmic microtubules, and extensive overlap of axonemes and nucleus. The new species can be easily distinguished from other Childia species by its viviparous mode of reproduction and single curved stylet. Observations on late embryonic development based on the oldest developing embryos are discussed.     

A new genus and a new species of Akicerinae (Orthoptera: Acridoidea: Pamphagidae) from Libya

Summary Seven species of cestodes and two of nematodes are reported from Phoeniconaias minor from Lake Nakuru, Kenya. Phoenicolepis nakurensis n.g., n.sp. (Hymenolepididae) is characterized by the size and shape of the hooks, scolex and strobila, structure of the terminal genital ducts, presence of an accessory sac, external seminal vesicle and stylet, and absence of an internal seminal vesicle. Gynandrotaenia stammeri. Cladogynia phoeniconaiadis, Flamingolepis tengizi, F. dolguschini and Striatofilaria phoenicopteri are redescribed; all except C. phoeniconaiadis are new for this host and for Kenya. ac]19800210Abbreviations as accessory sac - c cirrus - cs cirrus sac - esv external seminal vesicle - g gland cells - gs glandular sheath - isv internal seminal vesicle - md muscular duct - Mg Mehlis' gland - o ovary - pg prostate gland cells - s stylet - sr seminal receptacle - u uterus - v vagina - vd vas deferens - vg vitelline gland     

A new milliped of the Genus Chonodesmus,with a proposed reclassification of the family Cryptodesmidae (Diplopoda,Polydesmida)

Chonodemus gervaisi, n. sp., is described from San Agustín, Colombia. The genus Chonodesmus in many ways provides a link between the three nominal families Cryptodesmidae, Pterodesmidae, and Peridontodesmidae, and it is proposed that the three be combined into a single taxon, Cryptodesmidae, with the other two names retained for subordinate groups. A provisional classification of the family is suggested, including generic synonymy, and the new tribes Lampodesmini, Ophrydes‐mini, Dyakryptini, and Trichopeltini are proposed. The family name Otodesmidae is reduced to subfamily rank, and the name Niponiellidae reduced to tribal status. A key is provided for four West African genera of the subfamily Pterodesminae.     

Descriptions of the first semi-aphenopsian troglobiotic Patrobini and of a new anophthalmic cave-dwelling Trechini from central Sichuan,China (Coleoptera: Caraboidea)

Summary

The first known troglobiotic species belonging to the ground beetle tribe Patrobini is reported from a limestone cave called Lianhua Dong in Pengzhou, a suburb county-level city in northern Chengdu, Sichuan Province, China. Troglopatrobus zhouchaoi n. gen., n. sp., is an eyeless and large-sized patrobine beetle with extremely elongated body (esp. head and elytra) and appendages. Duvalioblemus (Shublemus) liyuani n. subgen., n. sp., a minute anophthalmic trechine species, is also discovered from the same cave. It is the first cave-dwelling species belonging to this genus already known as endogean from Sichuan and Yunnan provinces.

Die Namen der Familien und Unterfamilien der Lebermoose (Hepaticopsida)

Abstract

Part I deals briefly with the application of the Code rules to family and subfamily names.

In Part II full references are given for all family and subfamily names of Hepaticopsida, some with nomenclatural or taxonomic notes added. There are three lists, each in alphabetical order: A. legitimate names (78 f., 62 subf.), B. illegitimate names (21 f., 10 subf.), and C. invalid names (only those derived from generic names; 17 f., 11 subf.); in total 116 family and 83 subfamily names. Five family names (Choneoleaceae Schust., Conocephalaceae K. Müll., Exormothecaceae K. Müll., Oxymitraceae K. Müll., Perssoniellaceae Schust.) and three subfamily names (Allisonioideae Schust., Cololejeuneoideae Herz., Odontosehismatoideae Buch) are validated by Latin diagnosis. Five subfamily names (Hygrobielloideae (Joerg.) Schust., Isotaehidoideae (Hatch.) Grolle, Makinooideae (Nakai) Grolle, Mastigophoroideae (Nees) Grolle, Pallavicinioideae (Migula) (Grolle) are proposed by change of rank, whereas five other subfamily names (Acromastigoideae Grolle, Blepharostomatoideae Grolle, Cyathodioideae Grolle, Lethocoleoideae Grolle, Notothyladoideae Grolle) are newly proposed.

Part III is a taxonomic arrangement of the hepatic families and subfamilies. For each of the five orders of Hepaticopsida the accepted families (sixty-two in total) are listed alphabetically with full synonymy : Anthocerotales (1), Marchantiales (16), Metzgeriales (8), Calobryales (2), Jungermanniales (35). The accepted subfamilies with their synonyms are added to each family.     

Oriental bamboo leafhoppers: A new genus and two new species of Mukariinae (Hemiptera: Cicadellidae) from Southwest China and notes on related group

A new genus, Tiaobeinia n. gen., and two new species, T. bisubula n. sp. and T. emeiensis n. sp., breeding on bamboo in Southwest China, are described and illustrated. Based on the nature of the face, the apical veins of forewing and hindwing, the hind femur macrosetal formula, the valve, the subgenital plate, and the style, this genus should belong to the subfamily Mukariinae. The related genus Ratfronta Chen & Li 1997, placed previously in subfamily Nirvaninae, is noted in the present paper. A new combination, F. grandis (Ishihara 1961) n. comb., transferred from the genus Mohunia Distant, is proposed. Keys to the species of the new genus Tiaobeinia and the genus Flatfronta are provided. The importance of those groups as pests on bamboo is briefly discussed.
