Fianoniella stenognatha sp. n. from the Columbretes Islands (Castellón, Spain) is described and illustrated. The new species is distinguished by its longer and narrower mandibles with parallel or divergent rims in the apical half, wider clypeus, hind ocelli more separated and closer to the eyes, and longer flagellar segments. Additional notes to complete the original description of the closest species, F. laeviscutum (Horstmann), are given. A key to the European species of Fianoniella is provided.
European species of the genus Phradis Förster, 1869 are reviewed. A new species from Spain, Phradis mediterraneus sp. n., is described and illustrated. A key to all 24 European species and data on distribution and biology of these species are provided.
Two new species of Enclisis Townes, 1970 from Spain are described and illustrated: E. dichroma sp.n. and E. schwarzi sp.n. The new species are distinguished from the closest species E. infernator and E. ornaticeps by head and leg characters and body colour. Data on their phenology and a key to these four European species are presented. External and internal scanning electron microscopy of male tyloids revealed that these structures, in both new species, have a secretory role.
The subfamily Metriorrhynchinae is the most species-rich clade of Lycidae (Coleoptera). A recent proposal suggests that the Erotinae is a sister group of the Metriorrhynchinae. Within the Metriorrhynchinae, evidence is presented for the monophyly of the Conderini and Metriorrhynchini and their sister group position. The Trichalina, Hemiconderina and Metriorrhynchina form the tribe Metriorrhynchini. The relationships between the basal lineages of this group are poorly understood. Several clades are distinguished within the Metriorrhynchina, but there is only weak evidence supporting a relationships between them. The distribution of individual clades is discussed. Carathrix Kleine, 1926 (= Pseudodontocerus Pic, 1921), Dilolycus Kleine, 1926 (= Metriorrhynchus Gemminger et Harold, 1869), Flabelloporrostoma Pic, 1923 (= Metriorrhynchus Gemminger et Harold, 1869), Rossioptera Kasantsev, 1988 (= Xylobanellus Kleine, 1930), Samanga Pic, 1921 (= Broxylus C.O. Waterhouse, 1879), Strophicus C. O. Waterhouse, 1879 (= Enylus C.O. Waterhouse, 1879), and Tapromenoeus Bocak et Bocakova, 1989 (= Prometanoeus Kleine, 1925) are proposed as junior synonyms. Pseudosynchonnus Pic, 1922 is transferred to the Erotinae (Taphini) and Pseudosynchonnus Pic, 1922, Protaphes Kleine, 1926, and Parapyropterus Kleine, 1926 are proposed to be junior subjective synonyms of Lycoprogenthes Pic, 1915. Redescriptions of Metriorrhynchinae genera and a key to genera are provided.
Two new species of Polydictya Guérin-Méneville, 1844 from Vietnam, P. grootaerti sp. n. from Central Vietnam and P. drumonti sp. n. from North Vietnam, are described and compared with the closest species, P. chantrainei Nagai & Porion, 2004 and P. kuntzi Nagai & Porion, 2004. The male genitalia are described and illustrated for the two new species as well as for P. vietnamica Constant & Pham, 2008 for the first time. Habitus details and photographs, a distribution map and photographs of specimens in nature when available, are provided. The occurrence of P. vietnamica from Thailand and Northeast India, noted here for the first time based on photographs taken in nature, requires confirmation based on the examination of specimens. An identification key to the species of Polydictya from the Indochinese region is provided., Jérôme Constant, Hong-Thai Pham., and Obsahuje bibliografii
We compared the larval morphology of the genera Ataenius and Aphodius. The third larval instars of five Ataenius species: Ataenius opatrinus Harold, A. picinus Harold, A. platenis (Blanchard), A. simulator Harold and A. strigicauda Bates, are described or redescribed and illustrated. The most important morphological characteristics of the larvae of Ataenius are found in the respiratory plate of thoracic spiracle, the setation of venter of the last abdominal segment, the setation of the epicranial region and the morphology of the epipharynx. A key to larvae of the known species of Ataenius is included.
The larvae of Netocia morio (Fabricius, 1781), Netocia oblonga (Gory & Percheron, 1833), Potosia opaca (Fabricius, 1787) and Potosia cuprea brancoi Baraud 1992 are described. Comparison of the morphology of both genera revealed important differences in raster structure, mandibles and frontal setae. The systematic position of both genera based on larval characteristics is discussed. Some aspects of larval biology are discussed.
The third instar larvae of three Anisoplia species, Anisoplia baetica Erichson, 1847, Anisoplia depressa Erichson, 1847 and Anisoplia remota Reitter, 1889 are described and illustrated to show the diagnostic characters of the species. The third instar larva of the monospecific genus Anthoplia, represented by Anthoplia floricola (F., 1787) is also described and illustrated. These four species are included in a revised key to the larvae of Anisopliini, which now includes four genera, and ten species. The taxonomic status of Anthoplia based on the larval morphology, is discussed.
Genus-group taxa of Platerodinae are revised and valid taxa are redescribed. The validity of Plateros Bourgeois, 1879 is reinstated. Libnetomimus Kleine, 1927 is made a junior synonym of Libnetis Waterhouse, 1878. Calleros Gorham, 1881, Calloplateros Pic, 1923, Costatoplateros Pic, 1949, Ditoneces Waterhouse, 1879, Libnetomorphus Pic, 1921, Microplateros Pic, 1921, Planeteros Gorham, 1883, Tolianus Pic, 1921, Melampyrus Waterhouse, 1879, and the subgenus Cautirodes Pic, 1921 are considered to be junior synonyms of Plateros Bourgeois, 1879. The subgenus Pseudeuplectus Pic, 1922 is synonymized to Cavoplateros Pic, 1913, and Pseudoplateros Green, 1951 is made a junior synonym of Falsocalleros Pic, 1933. Macrolibnetis Pic, 1938 formerly classified with Platerodini is synonymized to Platerodrilus Pic, 1921. Samoaneros Blair, 1928 is considered to be a junior objective synonym of Melaneros Fairmaire, 1877, which is excluded from Platerodinae and is kept incertae sedis in Lycidae. Fernandum Pic, 1924 and Subdihammatus Kleine, 1926 are transferred to the subfamily Leptolycinae. Teroplas oculatus sp. n. and Microlycus mexicanus sp. n. are described. Neotype of Plateros brasiliensis (Lucas, 1857) and lectotype of Microlycus minutus Pic, 1922 are designated. In order to understand relationships within the subfamily, included genus-group taxa were cladistically analysed.
In this second part of the revision of Afrotropical Afrocrania Hincks, 1949 (= Pseudocrania Weise, 1892, not Pseudocrania MCoy, 1851), a group of Galerucinae restricted to Africa, additional material is revised. Herein, species in which the males lack deep head cavities, partly horned antennomeres, or extended elytral extrusions, but usually have small post-scutellar extrusions or depressions, are considered. Material of Afrocrania pauli (Weise, 1903), comb. n. (= Candezea pauli Weise, 1903), and A. famularis (Weise, 1904), comb. n. (= Monolepta famularis Weise, 1904; = Candezea atripennis Laboissière, 1931, syn. n.) is studied. Lectotypes are designated for A. pauli, A. famularis and C. atripennis. Six new species, A. aequatoriana sp. n., A. minima sp. n., A. nigra sp. n., A. occidentalis sp. n., A. pallida sp. n. and A. weisei sp. n. are described. Distribution patterns are mapped. Together with the already revised species there are 16 valid Afrocrania species are hitherto known. Its phylogenetic position within the Galerucinae is discussed, identification keys to males and females for all known taxa are presented.
