Three larval instars of Nearctic Agathidium angulare Mannerheim, 1852, are described in detail and the first and third stage larvae are figured for the first time; morphology of the stages was analyzed and compared, with special emphasis on measurements, chaetotaxy and porotaxy of head, mouthparts, thorax, abdomen, leg and urogomphi. Preliminary discussion on larval characters of the genus Agathidium is provided.

This is the first detailed description of the mature larva of Anisotoma discolor Melsheimer, 1844, a Nearctic member of the tribe Agathidiini. The setal pattern of cephalic capsule, mouthparts, legs, urogomphi, thoracic and abdominal segments are described and figured, and the measurements are given.

New localities of Platypsyllus castoris in Poland are reported. The species is newly reported from Pomeranian Lakeland, Podlasie and Kraków-Wieluń Upland.
EN
New distributional records concerning the occurrence of the genera Catops, Apocatops and Fissocatops (Coleoptera: Leiodidae: Cholevinae) in Poland are given. Fifteen species are recorded from new localities, and three of them are reported for the first time from new regions.
EN
Research on Cholevinae (Coleoptera: Leiodidae) of upland mixed fir forest in the Świętokrzyski National Park is presented. In 2008 twelve species from the area were revealed five of them were recorded for the first time from the park, and four are new to the Świętokrzyskie Mts. Seasonal patterns of abundance are shown for selected species.
EN
New faunistic data on the occurrence of 34 Leiodidae species in the environs of Radom (E Poland) is presented. The occurrence of Agathidium nudum in Poland is confirmed with new data. Several other rarely encountered species are reported, including Catops nigriclavis, Choleva sturmii, Agathidium mandibulare, Liodopria serricornis, Leiodes bicolor, L. oblonga, L. rubiginosa, and Platypsyllus castoris. Difficulties with identification of Central European Leiodidae are briefly discussed. To facilitate identification of Ptomaphagus species known from Poland, figures of aedeagi and spermathecae are provided.

The first, second and third larval instars of Agyrtodes crassus and an unknown species of Zearagytodes, and the third instar of Dictydiella turneri are described in detail, illustrated and measured. The details of their chaetotaxy and porotaxy are provided. Larval characters of Dictydiella leleupi are compared with those of D. turrieri. Morphological and chaetotaxic differences among mature larvae of the Agyrtodini genera Agyrtodes, Cholevomorpha, Dasypelates, Dictydiella, Eupelates, Paragyrtodes, Ragytodina and Zearagytodes are summarized. New morphological characters of Leiodidae larvae are documented and discussed.

One hundred thirty-four morphological characters were scored and analysed for larvae of twenty-four species of Camiarinae and fourteen species of other subfamilies of Leiodidae to test the monophyly of Camiarinae and determine phylogenetic relationships within tribes and genera. Two main clades were obtained. Some members of Agyrtodini (Dasypelates gracilis, Eupelates transversestrigosus and both species of Dictydiella) form a clade together with Cholevinae, while the remaining representatives of Agyrtodini, Neopelatopini and Camiarini were recovered as branches within a clade that also includes taxa from Catopocerinae, Leiodinae and Platypsyllinae. Within the latter clade, some of the Agyrtodes species, Zearagytodes and Ragytodina are grouped together, whereas Agyrtodes atropos and Cholevornorpha were placed as a sister group of all members of Paragyrtodes, Neopelatopini, Camiarini, Leiodinae, Platypsyllinae, and Catopocerinae. Camiarini and Neopelatopini except Myrmicholeva were recovered in one clade together with Agathidiini, whereas Myrmicholeva is sister to Platypsyllinae + (Catopocerinae + Pseudoliodini) and this clade is the sister to Paragyrtodes. The analysis strongly supports the view that Camiarinae and its tribes are paraphyletic, grouping possibly ancient and relict taxa that are or have evolved from ancestors of the other subfamilies. However, the obtained clades have low support values, and the results cannot be used to propose a robust, phylogeny-based classification of Leiodidae. The results support previously postulated informal groups, and provide a new insight into relationships within the subfamily Camiarinae as well as the family. A species checklist of described larvae is provided for world Leiodidae, and the habitus and the most interesting or previously unknown larval characters of Camiarinae are illustrated and discussed.
