Process of transformation in legs and antennae, which takes place in Orthezia urticae (Linnaeus, 1758) in course of molt from one instar to another, disagrees with modes of life of these instars. Each molt from one actively feeding instar to another (these are two first instars of male and all instars of female) is accompanied with deep degeneration, dedifferentiation, new differentiation and subsequent growth of each appendage; proximal segment of each appendage newly grows in an unusual inverted condition and everts only during ecdysis. Unlike this, quiescent instars of male molt like most other insects, so that molting processes do not cause immobility of their appendages. Examination of some other coccid species allows to assume that this alternation of molt modes is usual for Gallinsecta. Possibly, this character is initial for Gallinsecta and is connected with existence of leg-less feeding instars in non-related representatives. To describe processes which take place at metamorphosis, new terms for preimaginal instars of Pterygota are introduced. New taxa names PSYLLALEYRODA taxon nov. and APHIDOCOCCA taxon nov. are suggested.

Abstract We describe two new species of the freshwater-crab genus Demanietta  Bott, 1966 from Tanintharyi (Tenasserim) division, southern Myanmar (Burma), Demanietta liui  sp. nov. and Demanietta lenya  sp. nov.  Demanietta liui  sp. nov. is morphologically most similar to D. thagatensis  Rathbun, 1904 and D. khirikhan  Yeo, Naiyanetr & Ng, 1999; D. lenya  sp. nov. appears close to D. manii  Rathbun, 1904, D. merguensis  Bott, 1966, and D. nakhonsi  Yeo, Naiyanetr & Ng, 1999. The two new species are easily distinguished from their most similar congeners in the shape of the external orbital tooth, epibranchial tooth, and male first gonopod. Molecular analysis based on partial mitochondrial 16S rDNA also supports the systematic position of the new taxa.

ABSTRACTAll taxa of Orthoptera known from the latest Eocene deposits of the Isle of Wight are redescribed or discussed, based on the study of their type material. The following new taxa are described: Ontogryllus gen. nov., O. rossi sp. nov. (type species), Achetomorpha gen. nov., A. irregularis sp. nov. (type species), and Proeneopterotrypus gen. nov. The latter genus is here proposed for Pteroplistes danicus Rust, described from the Palaeocene/Eocene of Denmark, as this find is important for understanding the systematic position of the genus Eneopterotrypus Zeuner. Remarks about the taxonomy of the taxa studied, age of these deposits, and ecology are given.

Melissoaspis n.gen. is established for two species, namely Melissoaspis fisheri n. sp. and Melissoaspis reticulata n. sp., and a further new species is also described, Morganella formicaria n. sp. all from Madagascar. All the above-mentioned scale insects were collected from galleries of the ant Melissotarsus insularis Santschi (Hymenoptera: Formicidae) on the trunk of various species of host plants in Madagascar. New data on the distribution, host plants and life history are given for Melanaspis madagascariensis Mamet, and for Morganella conspicua (Brain).

AbstractThe Chinese representatives of the tribe Ducetiini are partly revised. The paper includes descriptions of new taxa (Ducetia borealis sp. n., Kuwayamaea inflata sp. n., K. anhuii sp. n., K. fujiani sp. n., K. hunani sp. n., K. brachyptera sp. n., Prohimerta guizhouensis sp. n., P. fujianensis sp. n., P. hubeiensis sp. n., P. sichuanensis sp. n., Shirakisotima furca sp. n., Paraducetia paracruciata gen. & sp. n.) and of the previously unknown female of Sh. brevifissa Wang & Liu, identification keys to genera and species of Chinese Ducetiini for males, notes about systematic position and distribution of the taxa examined [the former genus Anisotima Bey-Bienko is a subgenus of the genus Prohimerta Hebard; Sh. acuminata Wang & Liu is possibly a junior synonym of Sh. multipunctata (Kang & Yang); some published data on distribution of K. sapporensis Matsumura & Shiraki, Prohimerta yunnana (Bey-Bienko), and Paraducetia cruciata (Brunner von Wattenwyl) are probably erroneous].

ABSTRACTThe records of columnar shell structures of linguloid brachiopods (Class Lingulata, Order Lingulida, Superfamily Linguloidea) are reviewed in the light of the discovery of two new taxa from the Middle Cambrian Forsemölla Limestone Bed of southern Sweden. The linguloid taxa, described here as Eoobolus? sp. aff. E. priscus (Poulsen) and Canalilatus? simplex sp. nov., are both characterised by a columnar shell structure, a structural type that is representative for acrotretoid brachiopods and that has previously only rarely been reported from the linguloids. Though the two taxa are superficially similar to known genera, i.e., Eoobolus and Canalilatus, their shell structure challenges such affiliations, as the shell structure of the type species of these genera is previously unknown. Linguloid families whose morphological characteristics agree the most with those of the new taxa, i.e., the Zhanatellidae and the Eoobolidae, and from which columnar shell structures have been reported, i.e., the Lingulellotretidae and the Kyrshabaktellidae, are reviewed briefly. Many taxa assigned to these families completely lack shell structure data and are in need of restudy in order to elucidate their systematic position. Knowledge of the representative type of shell structure of the various suprageneric taxa within the Linguloidea is considered crucial, in order to unravel their currently poorly resolved phylogenetic relationships.

Keys for subgenera of the genera Hapithus and Cylindrogryllus Sauss. are given; the former genus Neometrypus Desutter is included in the latter genus as its subgenus; H. aphaeretos Otte et Perez-Gelabert, syn. nov. is synonymized to H. kerzhneri Gor.; a new female of the latter species is described; the former species Aphonomorphus desutterae Cadena-Castañeda et Noriega and subspecies Paroecanthus aztecus verapas Gor. are considered as a subspecies (A. solitarius desutterae stat. nov.) and a species (P. verapas stat. nov.), respectively; systematic position and distribution of some other taxa are clarified.

Two almost complete long-tailed pterosaurs from the Linglongta, Jianchang County, western Liaoning, China, are described and represent new taxa referred to the non-pterodactyloid clade Wukongopteridae. Kunpengopterus sinensis gen. et sp. nov. differs from other members of this clade mainly by the rounded posterior region of the skull, thick lacrimal process of the jugal and lack of a bony premaxillary crest. This species further shows a soft tissue crest above the frontal, a comparatively larger wing finger, and the proximal segment of the second pedal phalanx of the fifth toe shorter than in other wukongopterids. The second new species is referred to the genus Darwinopterus, D. linglongtaensis sp. nov. based on the posterior region of the skull. It further differs from other wukongopterid pterosaurs by the thin lacrimal process of the jugal, foramen on nasal process rounded, and by having the second pedal phalanx of the fifth toe less curved (115°). Several differences among the Wukongopteridae can be found in the dentition and the feet, suggesting that they might have occupied slightly different ecological niches. The long-tailed Changchengopterus pani is tentatively referred to this clade and new diagnosis for the wukongopterids Wukongopterus lii and Darwinopterus modularis is provided.

AbstractThe purpose of this paper is a comparative morphological study of the little known monotypic weevil genus Araxia Khnzorian, 1957 and its close allies; redescriptions and figures are provided. A new systematic position for Araxia is proposed and discussed, its affinity with Chiloneus Schoenherr, 1842 and a new genus Holcolydoprus gen. n. is demonstrated. A new genus Holcolydoprus gen. n. is described with two new species H. bimaculatus sp. n. (type species) from Turkmenistan and H. griseus sp. n. from Transcaucasia and Eastern Turkey. The genus Aomus Schoenherr, 1834 is transferred from the tribe Laparocerini to Sciaphilini, its affinity with Eusomomorphus K. Daniel, 1905 is demonstrated. A new combination Eusomomorphus ilerii (Fremuth & Lodos, 1987), comb. n. is established for Aomus ilerii. A key to genera centering around Araxia is given.
