Prey preferences and feeding-related behaviour of a Central European species of Scydmaeninae, Scydmaenus rufus, were studied under laboratory conditions. Results of prey choice experiments involving 22 identified species of mites belonging to 13 families of Oribatida and two families of Mesostigmata (Uropodina) demonstrated that this beetle feeds mostly on oribatid Schelorib­ atidae (60.38% of prey) and Oppiidae (29.75%) and only occasionally on uropodine Urodinychidae (4.42%) and oribatid Mycobatidae (3.39%); species belonging to Trematuridae (Uropodina), Ceratozetidae and Tectocepheidae (Oribatida) were consumed occasionally. The number of mites consumed per beetle per day was 1.42, and when Oppia nitens was the prey, the entire feeding process took 2.93–5.58 h. Observations revealed that mechanisms for overcoming the prey’s defences depended on the body form of the mite. When attacking oribatids, with long and spiny legs, the beetles cut off one or two legs before killing the mite by inserting one mandible into its gnathosomal opening.

Prey preferences and feeding-related behaviour of a Central European species of Scydmaeninae, Euconnus pubicollis, were studied under laboratory conditions. Results of prey choice experiments involving 50 species of mites belonging to 24 families of Oribatida and one family of Uropodina demonstrated that beetles feed mostly on ptyctimous Phthiracaridae (over 90% of prey) and only occasionally on Achipteriidae, Chamobatidae, Steganacaridae, Oribatellidae, Ceratozetidae, Euphthiracaridae and Galumni- dae. The average number of mites consumed per beetle per day was 0.27 ± 0.07, and the entire feeding process took 2.15–33.7 h and showed a clear linear relationship with prey body length. Observations revealed a previously unknown mechanism for capturing prey in Scydmaeninae in which a droplet of liquid that exudes from the mouth onto the dorsal surface of the predator’s mouthparts adheres to the mite’s cuticle. Morphological adaptations associated with this strategy include the flattened distal parts of the maxillae, whereas the mandibles play a minor role in capturing prey.

  • The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
    INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

CHINA 2 Hebei Finance University, 3188 Hengxiang North Street, 071051, Baoding, Hebei, P.R. CHINA * Corresponding author: [email protected] Abstract The aim of the study was to explore the feasibility of a geometric morphometric method for the ecological classification and identification of moths according to taxonomic ecology. Ten species of Sphingidae were used as examples in this paper. The right forewings from the ten species were used as the research object, and seventeen landmarks in environment were selected for analysis. Two related steps including geometric morphometric analysis and multivariate statistical analysis were carried out. In the first step, Procrustes superimposition was applied to the data of the seventeen environmental landmarks by removing nonshape variation from the landmark coordinates. Using relative warp analysis, relative warp figures and a matrix of relative warp scores were obtained. In the second step, ecological component analysis of the Procrustes- transformed data set was implemented, and three dimensional distribution figures for the ten species of Sphingidae were described on the basis of the first three components. Discriminant analysis was carried out on the relative warp scores matrix, and accuracy of original and cross-validation tests achieved 100% and 99.7%, respectively. The results indicate that geometric morphometric analysis may be used to accurately identify the ten species of Sphingidae, and their taxonomy can be achieved using relative warp figures.

This study on Silphidae fauna was carried out at different sites forming part of an agricultural landscape. Catches were carried out in two selected habitats (Borek Stary and Widna Góra) in the Subcarpathian region (south-eastern Poland) during three growing seasons (2009-2010 and 2014) using Barber pitfall traps. It included potato, fodder beet and cereal crops (Widna Góra) as well as field margins (Borek Stary and Widna Góra). Four traps were placed at each of the sites studied then were emptied on average every two weeks. As a result of the observations, a total of 5491 beetles from 13 species were collected. Keywords: Silphidae, Thanatophilus sinuatus, Nicrophorus vespillo, crop culture, field margins Introduction Most representatives of carrion beetles (Col., Silphidae) are necrophagous and/or predatory. Herbivorous species are a minority (Anderson and Peck, 1985; Sikes, 2008). Alongside ground beetles (Col., Carabidae) and rove beetles (Col., Staphylinidae), beetles from this family are an important component of epigeic entomofauna of agricultural landscape from the ecological point of view (Tischler, 1955). Necrophagous carrion beetles perform important ecological functions, which can be particularly seen in the agricultural aspect. Biochemical transformations that accompany the decomposition of dead animals lead to an increased amount of mineral nutrients and humus in the soil and, as a further consequence, they affect soil fertility regeneration.

E-mail: [email protected] Abstract The mature larva of Stenichnus collaris is re-described on the basis of a shed larval skin. This is the first description of an immature Stenichnus identified by rearing to an adult beetle, and not only by collecting the larva in association with adults, as in previously published works. New data on the life history of St. collaris are provided, and possible serial homology of chaetotaxic structures across body segments is discussed. The structures of immature Nearctic St. turbatus, the only Stenichnus larva described with focus on the chaetotaxy, are compared with those of St. collaris and possible homologies are indicated. Key words: Coleoptera, Staphylinidae, Scydmaeninae, Cyrtoscydmini, Stenichnus, larval morphology, Palaearctic. Introduction Larvae of less than 0.5% of named Scydmaeninae species have been described (Jałoszyński & Kilian 2012), and morphological structures of most of them are known insufficiently. Modern standards of accurate illustrating and precise mapping chaetotaxic structures were met only in a few descriptions, while the majority of papers containing larval characters give only fragmentary and often imprecise details. Even immature stages of Central European Scydmaeninae are poorly known, and in some cases descriptions of the same species published by various authors show structures different to such an extent that their identifications seem dubious.

Ant-like stone beetles (Coleoptera: Scydmaenidae) include more than 4,850 described species in about 90 genera main- tained as a separate cosmopolitan family since 1815. Recent authors have hypothesised that Scydmaenidae might be rooted deep inside rove-beetles (Staphylinidae). To test this hypothesis we analysed 206 parsimoniously informative larval and adult morpho- logical characters scored for 38 taxa. Strict consensus topologies from the shortest trees in all 12 analyses consistently placed Scyd- maenidae as sister to (Steninae + Euaesthetinae) in a monophyletic Staphylinine Group (with or without Oxyporinae). The single fully resolved and most consistently supported topology maintains a monophyletic Staphylinine Group consisting of Oxyporinae + (Megalopsidiinae + ((“Scydmaenidae” + (Steninae + Euaesthetinae)) + (Leptotyphlinae + (Pseudopsinae + (Paederinae + Staphylini- nae))))); Solierius lacks larval data and is ambiguously placed within the Group.
