Species of the chalcidoid genus Eurytoma associated with stone fruits are studied for the Palaearctic region. The eight species known to have such an association are: E. amygdali Enderlein, E. maslovskii Nikol'skaya, E. padi Veresh-chagin, E. samsonowi Vasiljev, E. schreineri Schreiner, E. turkestanica sp. n., E. paramygdali sp. n. and E. armenica sp. n. The first six species are phytophagous, developing in the stones, and the last two are entomophytophages, starting their development as parasitoids of a phytophagous species and completing development feeding on plant tissue. Four species, E. amygdali, E. schreineri, E. samsonowi, and E. maslovskii are of economic importance. Information is given on the economic importance, biology, distribution and taxonomy of these species, and includes several new records for hosts and distribution. A key is given to distinguish the species.

Darkling beetle Zophobas atratus (Coleoptera, Tenebrionidae) is recorded here for the first time as a new species for the fauna of Ukraine. Detailed study on morphology of preimaginal stages and biology of this species recently introduced to Ukraine, is given here. Zophobas atratus is an important species being easily reared in laboratory cultures and widely distributed in North and South America, Europe, and Asia. Detailed descriptions of all life stages, including egg, young and older larvae, pupa and adult of Z. atratus are required for further taxonomical study of the genus Zophobas, which isn’t yet definitively established. New identification keys for adults and larvae of the genera of tribe Tenebrionini are presented here, based on a comparative analysis of the taxonomic characters of adults and larvae of Z. atratus and species from the genera Tenebrio and Neatus. Comparative analysis of morphology of larva of Z. atratus and larvae of the tribe Cteniopodini of close subfamily Alleculinae was conducted here. The subfamily Alleculinae previously had the rank of family Alleculidae, but our analysis confirmed the reliability of its current taxonomic position as subfamily. The study of morphology of larvae of 1st and 2nd instars of Z. atratus revealed that they are characterized by special taxonomic structures that are not characteristic for oldest instars of larvae of Z. atratus. These characters include absence of spines on caudal segment, presence of a set of 4 setae at posterior margin of tergites of prothorax, metathorax, and 1st to 8th abdominal segments, strongly convex 2nd antennal segment and sensory zone in the form of an open ring on its apex, and etc. Moreover, structure of antenna of larvae of Z. atratus is similar to that of oldest larvae of most species of darkling beetles of the fauna of Ukraine. The most distinctive features of Z. atratus are: sexual dimorphism in structure of clypeus of adults; filiform sclerotized antenna of larva with a continuous sensory zone at apex of 2nd segment, weakly developed 3rd segment; fusion of sclerotized pleurites of 1st–8th abdominal segments with their tergites; sexual dimorphism in structure of 9th abdominal segment of pupa, and presence of two hooks on apex of its appendages. The data of original study of features of life cycle of Z. atratus are given. The pictures and photos of details of morphology of egg, larvae, pupa and adult of Z. atratus are presented. It was recored that life cycle of Z. atratus from laying of egg to the emergence of adult continues from 169 up to 181 days. Adults lived maximum up to 206 days. Maturation of eggs in female after copulation continues 10-11 days. Stage of egg continues 7 days, larva – up to 151 days, including pre-pupal period from 6 to 22 days, pupa – from 8 to 21 days. Twelve larval stages of Z. atratus were recorded in laboratory culture.

Redescription of T. phragmitis (Erdös) based on type material is given, along with new data on its distribution in Ukraine, Moldova, Russia, Israel, Tajikistan and Japan.

Eurytoma gleditsiae sp. n. reared from the seeds of Gleditsia triacanthos L. (Caesalpiniaceae) in Kyiv, Ukraine, is described. The new species apparently parasitize Megabruchidius dorsalis (Farhaeus) (Coleoptera, Bruchidae).

Two new minute egg parasitoid wasp species belonging to the genus Trichogramma (Hymenoptera: Trichogrammatidae), T. chagres sp. nov. and T. soberania sp. nov., were found in a tropical lowland rainforest in Panama, Central America. In this paper, we describe, illustrate and discuss the biology and morphological and molecular characterization of the two new Trichogramma wasp species. Both species were collected from eggs of passion vine butterflies, Agraulis vanillae vanillae (Lepidoptera: Nymphalidae: Heliconiinae) and unidentified Heliconiini species, laid on different Passiflora species (Malpighiales: Passifloraceae). A female T. soberania sp. nov. wasp was observed on the wings of a female Heliconius hecale melicerta butterfly caught in the wild. This suggests that this species may occasionally be phoretic on adult female butterflies to find suitable host eggs. Our study adds two more species identifications to the scarce record of Trichogramma wasps from the widespread Heliconiini butterflies in Central America. urn:lsid:zoobank.

Th e fauna of the family Dolichopodidae of Japan is not fully studied until now, despite that currently more than 120 species are known from this area. While in the view of its boundary location between the Oriental and Palaearctic Regions the fauna of this area consists of about 300 species of the family Dolichopodidae.By the present time only seven species of the genus Dolichopus Latreille were recorded from Japan: Dolichopus crassicosta
