Genus Lepidocyrtus is represented by 25 species in Europe and the correct identification of some of them is difficult to achieve due to lack of diagnostic characters and some published errors description. In this paper I have studied specimens of Lepidocyrtus flexicollis, L. curvicollis, L. monseniensis and L. nigrescens and I have found several diagnostic characters very useful for their differentiation. The total chaetotaxy of fourth abdominal tergum is very informative for these four species and could be for the whole European species. I have consulted the literature that describes the European species and I made a diagnosis of all of them using the best diagnostic characters possible, with which I have elaborated an identification species key. The high chromatic variability of some European species makes the use of color pattern for taxonomy on this region problematic.

In the tenthredinid hymenopteran genus Empria, the European species with a paired whitish patch on tergum 1 are considered tentatively as a species-group termed the E. hungarica group. The type materials of Empria pumila (Konow), E. pumiloides Lindqvist and E. tricornis Lindqvist were examined. The lectotype and paralectotypes of E. pumila are designated, and new diagnostic characters for E. pumila and E. pumiloides are given. A key for the Northern European species of the E. hungarica group is compiled. The results of a comparison of the phenology and some metrical characters of the adults of E. pumila and E. pumiloides are presented in the form of diagrams. E. pumiloides is recorded for the first time from Russia and Germany. The records of E. hungarica from Estonia (Saaremaa) are reported as the northernmost for that species. All available distributional records of Empria hungarica in the Palaearctic are given in the text, and those localized reliably are also mapped.

The final stadium larva of Megalestes heros Needham, 1930 is redescribed and illustrated in detail. It is characterized by having a long and cylindrical body, a very long prementum with two end hooks of unequal size on lateral lobe, parallel wing sheaths, long and slender legs, female ovipositor short reaching the basal third of S10, and based on a distinct abdominal color pattern. The major diagnostic characters of the larvae of the genus Megalestes are as follows: (1) body smooth and slender, with long abdomen and leaf-shaped caudal gills; (2) antenna filiform, seven-segmented,third segment longest; (3) median cleft present in median lobe of prementum; lateral lobe with two end hooks of unequal size, the inner one being longer and larger than the outer, movable hook without setae; (4) wing sheaths parallel to each other.

Immature stages of Murgantia histrionica (Hemiptera: Pentatomidae) are described using light and scanning electron microscopy. Specimens of all life stages of M. histrionica were collected on Peritoma arborea (Cleomaceae) in Palm Springs, California. Specimens were observed in light and scanning microscopies, imagens taken and described based on specimens and photographs. We provide images of the eggs and immatures in light microscopy, and SEM of the eggs and first and fifth instars. Eggs of M. histrionica are barrel-shaped, white, with brown band and circular spot; the corium surface carinated, forming hexagonal cells; carinae irregular apically. The nymphal color pattern; the reflexed lateral margins of pro- and mesothorax; and the scattered punctuation of the tegument are a combination of characteristics enabling M. histrionica identification in its nymphal stages. The eggs of M. histrionica are similar in shape, color, and size to other Strachiini genera, such as Bagrada, Eurydema and Stenozygum. Among the Strachiini, the correct identification of M. histrionica based on immatures is possible by the shape of the head and pronotum, overall size of immatures, and coloration patterns.

Two new species of Diplura C. L. Koch 1850 are described from Brazil: Dipluramapinguari sp. n., from the state of Rondônia in southeastern Amazonia, northern Brazil, and Diplurarodrigoi sp. n., known from southeastern and central west regions of Brazil. Diplurarodrigoi sp. n. is morphologically similar to D.lineata (Lucas, 1857), D.sanguinea (F. O. Pickard-Cambridge, 1896), and D.mapinguari sp. n. Comments on diagnostic characters of Diplura are included. The synonymy of D.maculata (Mello-Leitão, 1927) with D.catharinensis (Mello-Leitão, 1923) is corroborated. A classification of color pattern of the dorsum of the abdomen is given.

Degree Of Similarity

Studies of recruitment dynamics in meroplanktonic organisms are dependent on the correct identification of each ontogenic stage of each species. This is particularly difficult when studying the larval stages, which are not easy to identify due to their lack of resemblance to conspecific adults and their high degree of similarity with congenerics at the same stage of development. This is the case with the crustacean megalopae of the genus Cancer along the coast of the south-eastern Pacific. This fact represents a serious limitation on ecological studies of populations of these species which constitute a heavily exploited local resource. In this study we describe in detail field collected megalopae larvae of three sympatric crab species of the genus Cancer(C. edwardsii, C. setosus and C. coronatus). As a result of this analysis we were able to identify easily visible diagnostic characters which allow the species to be distinguished from one another. The megalopae were easily distinguished by the form of the cheliped and the presence of spines on these. Cancer edwardsii has an elongated globulose cheliped, whereas C. coronatus has a subquadrate one. Both species possess a prominent ischial spine, which is absent in C. setosus. We corroborated the utility of these diagnostic characters by comparing the COI gene sequences of mitochondrial DNA of larvae identified by morphology with sequences taken from samples of the adults of all species of Cancer found in the region. We discuss the morphological variations between larvae found across the region (i.e. at sites separated by more than 800 km) and between megalopae obtained from the field versus those cultivated in the laboratory. We conclude that the simultaneous use of morphological and molecular tools for identification of decapod larvae appears useful for the study of cryptic species.

AbstractA revision of the European species of Siphona Meigen (1803) is presented. New diagnostic characters, especially based on structural differences in the male and female genitalia, are introduced. Also the traditionally used characters are revised. Four species are described as new: ingerae, mesnili and variutu from Denmark, and martini from Sweden. Thirteen other species are diagnosed. All seventeen species are keyed, and details of the genitalia are illustrated. Two lectotypes are designated. Notes on the affinities and distribution of the species are given. The biology is reviewed and possible host-parasite relationships are presented in an annotated list. True aerial swarming (synorchesia) of male Tachinidae is reported for the first time.

A review of 29 European species of the genus Phyllonorycter Hübner, 1822 developing on the plants of the tribe Genisteae with diagnostic characters, brief data on their biology and distribution is given. Twelve of them are new: Phyllonorycter estrela sp. n., probably from Genista cinerea (Vill.) DC., P. telinella sp. n. from Genista monspessulana (L.) L. A. S. Johnson, P. tridentatae sp. n. from Genista tridentata L., P. deschkanus sp. n. from Genista cinerea (Vill.) DC., P. andalusicus sp. n. probably from Retama sphaerocarpa (L.) Boiss., P. echinosparti sp. n. from Echinospartum lusitanicum (L.) Rothm., P. baetica sp. n. from Genista versicolor Boiss., P. vueltas sp. n. from Genista florida L. and G. cinerea (Vill.) DC., P. scorpius sp. n. from Genista scorpius (L.) DC., P. pumila sp. n. from Genista versicolor subsp. pumila (Hervier) Fern. Casas, P. eugregori sp. n. from Cytisus austriacus L. and C. ratisbonensis Schaeff., and P. etnensis sp. n. from Genista aetnensis (Biv.) DC. Phyllonorycter purgantella (Chrétien, 1915) is recognized as bona species. Phyllonorycter dalmatinella (Amsel, 1951) and P. picardi Buvat, 1995 are junior subjective synonyms of Phyllonorycter lapadiella (Krone, 1909). The lectotype of Phyllonorycter haasi (Rebel, 1901) is designated. The species are divided into three species groups, Phyllonorycter cerasinella (Reutti, 1853) standing apart from these groups. New country records of several species are given.

A New Species

Four Atlantic species of the flustrid genus Hincksina Norman, 1903, which were introduced during the 19th and early 20th century, are redescribed and imaged: Hincksina flustroides (Hincks, 1877) from Great Britain, Hincksina sceletos (Busk, 1858) from Madeira as well as Hincksina neptuni (Jullien in Jullien & Calvet, 1903) n. comb. and Hincksina alice (Jullien in Jullien & Calvet, 1903) n. comb. from the Azores, the latter two of which were hitherto placed in the cribrilinid genus Membraniporella Smitt, 1873. Lectotypes are designated for all species. A new species, Hincksina synchysia n. sp., is introduced for the Mediterranean taxon previously referred to as Hincksina flustroides f. crassispinata Gautier, 1962. In contrast to species from the continental shelf, which have simple cylindrical or flattened spines, some of the species from the oceanic islands of Madeira and the Azores are particularly characterised by falciform and variably formed palmicorn spines. Moreover, whilst most Hincksina species have avicularia with a relatively short, (sub)rounded rostrum and mandible, the two Azorean species have elongated, curved and pointed avicularia. The relationship between Gregarinidra Barroso, 1949, which also has pointed avicularia, and Hincksina is commented upon. Based on several shared diagnostic characters, the genus Cribralaria Silén, 1941 is here transferred from the Cribrilinidae Hincks, 1879 to the Flustridae Fleming, 1828.

A New Species

Liolaemus dorbignyi is re-described, and its type locality restricted to the Sierra de Fiambalá, Catamarca Province, Argentina. Also, Liolaemus scrocchii sp. nov., a new species of Liolaemus belonging to the L. montanus series, previously confused with L. dorbignyi , is described. This new species inhabits the phytogeographic region of Puna in Argentina at 3500 m. and is distributed in Jujuy and northwestern Salta provinces. Diagnostic characters include the color pattern, (composed of transverse paravertebral spots, that are band shaped and never reach the lateral region, and never contact the vertebral zone), and the number of scales around midbody. Several populations from different localities were considered L. dorbignyi because of their color pattern and squamation. Even though part of this confusion is clarified in this contribution, some populations still require further study.
