This article provides morphological and molecular characteristics of Punctodera stonei Brzeski, 1998. Comparison of partial sequences of 18S and 28S rDNA genes from P. stonei sampled in Poland and Punctodera sp. from Canada showed their 100% similarity. This is the first report on the occurrence of P. stonei outside of Europe. We provide data on morphology of males and 2^nd stage juveniles of this species and an identification key to males of the genus Punctodera Mulvey et Stone, 1976. Moreover, the paper presents evolutionary relationships of P. stonei within the family Heteroderidae.

European populations of Aporcella vitrinus, mainly collected in natural habitats of southeastern Iberian Peninsula are studied and described, including SEM observations and the first report of the male. They are characterized by its body 1.20–1.86 mm long, lateral chord bearing gland bodies, lip region offset by weak constriction and 11–13 µm broad, odontostyle 12–13 µm long, neck 333–374 µm long, pharyngeal expansion 149–185 µm long or 44–51% of total neck length, uterus simple and 28–48 µm long or 0.6–1.2 times the corresponding body diameter, pars refringens vaginae absent, V = 48–53, tail convex conoid (21–31 µm, c = 45–77, c' = 0.9–1.4), spicules 43 µm long, and six irregularly spaced ventromedian supplements with hiatus. European specimens are compared to type American ones, but do not differ significantly from these although morphometrical ranges are wider in European material. SEM pictures show a symmetrically biradial lip region pattern, totally similar to that found in Aporcelaimellus.

Dolicheremaeus contactus sp. nov. is distinguishable from other species of the genus by the presence of the following character states in combination: sensilli bacilliform; all condyles present, and lateral prodorsal and notogastral condyles densely contacted with each other; 10 pairs of notogastral setae of medium size, straight, barbed; adanal lyrifissures located in paraanal position; adanal setae inserted nearly to margin of the ventral plate. Unguizetes latus sp. nov. is distinguishable from other species of the genus by the presence of the following character states in combination: sensili clavate; rostrum rounded; distinct translamella absent; lamellae with lateral tooth; prolamellar line developed; pteromorphs well developed; porose areas A1 rounded, Aa, A2, A3 oval; five pairs of genital plates present. Galumnella tiunovi sp. nov. is distinguishable from other species of the genus by the presence of the following character states in combination: prodorsum with two large teeth laterally; sensilli setiform; rostral setae developed, lamellar and interlamellar setae represented by alveoli; body surface microfoveolate, without reticular pattern; genital setae inserted in two rows on each plate; postanal porose area absent.

The data on host-parasite associations between Hemiptera and terrestrial Parasitengona mites are summarized and supplemented with new records. The species names of parasitic mites are verified according to the most recent data. Altogether, representatives of 26 parasitengone genera are known to parasitize bugs.

Thalassaphorura is reported for the first time in Northwest China. Four members of the genus were recorded, including three new species (T. qinlingensis sp. nov., T. bisetosa sp. nov., T. petiti sp. nov.) and one known species (T. pomorskii Sun, Chen et Deharveng, 2010). All three new species possess modified chaetae (male ventral organ) on ventral tube — a character rarely present in congeners. Apart from this, T. bisetosa sp. nov. is characterized by an unique feature — only two small dental chaetae on the furcal area, which differentiates it from all other known Thalassaphorura.

Details on the rearing process and feeding behavior in laboratory are given.

Phylogenetic relationships within the family Rhipiceridae were investigated to elucidate the relationships between genera and subgenera of Rhipicerinae. Eleven ingroup taxa and three outgroups were included in cladistic analysis, based on 34 characters derived from adult morphology. Phylogenetic analysis confirms that Rhipicerinae are monophyletic and may be divided into four genera: Oligorhipi. (stat. nov.), Polymeriu., Polytomu. (stat. rev.) and Rhipicera. All genera of Rhipicerinae are thoroughly described, illustrated and key to their identification is provided. Species level reviews and keys are provided for Oligorhipi. and Rhipicera. Two new species are described: Oligorhipis vanemden. sp. nov. (Western Australia) and Rhipicera carinat. sp. nov. (Western Australia). Rhipicera abdominali. Klug, 1825, R. cyane. Castelnau, 1834, R. dalmann. Westwood, 1837 and R. marginat. Kirby, 1818 are transferred to Polytomu. Dalman (comb. nov.). Agathorhipis bifossat. Fauvel, 1904 and Ptiocerus vestitu. Castelnau, 1840 are transferred to Oligorhipi. Guérin-Méneville, 1843 (comb, nov.). Agathorhipi. Guérin-Méneville, 1843 is synonymised with Rhipicer. Latreille, 1817 (syn. nov.) and Rhipicer. (Agathorhipi.) neglect. Emden, 1925 with Rhipicera femorat. Kirby, 1819 (syn. nov.). The neotype of Rhipicera reiche. Guérin-Méneville, 1843 is designated to stabilize the taxonomic identity of this species.

Lepidocaulinus gen. nov. and its type species L. mirabilis sp. nov. (Coleoptera: Tenebrionidae: Stenochiinae) are described from Thailand. The new genus is related to Pigeocaulinus Kaszab, 1984 (= Leprocaulinus Kaszab, 1982, not Leprocaulinus Uvarov, 1940), and to Hexarhopalus Fairmaire, 1891. Pigeocaulinus sumatranus Kaszab, 1984 is considered as a new synonym of Pigeocaulinus krikkeni (Kaszab, 1982). Neotype is designated for Pigeocaulinus sumatranus Kaszab, 1984.

An X-ray microtomographic analysis of the prothoracic skeleton structure of seven Platynotina species is presented. The investigated taxa represent different morphological types of pronotal discs. Tenebrio molitor was used as a reference model to all taxonomic considerations. The anatomical evidence gathered and analyzed in this study indicates that lateral indentations of nota, which are visible in most of the Ectateus generic group representatives, corresponds with a placement of the attachments of the pleural apophyses to the bottom of pronotal disc. Therefore, they should be defined as the apophyseal depressions. Furthermore, the main observed differences between the thoracic structure of the species with conspicuous apophyseal depressions and convex pronotal nota concerns the height of the pronotal disc and the elevation of its edges. The current investigations did not revealed any significant modifications of the endoskeletal structure between the prothoraces with or without the basal indentations. The study shows that X-ray microtomographic analysis is a powerful, non-destructive tool for the taxonomic considerations and that it can be safely applied to the name-bearing types. Furthermore, the application of this method, even to the dried entomological material, may provide many advantages over traditional morphological investigations.
