ABSTRACT
A new fossil cockroach, Ectobius danekrae sp. nov., is described on the basis of a single male adult individual from late Eocene Danish amber. This is the third representative of the genus Ectobius Stephens, 1835 from Eocene ambers. The new species exhibits plesiomorphic characters of small right stylus and subsymmetrical claws, compared to the known fossil and living species of the genus. The references to Ectobius balticus (Germar et Berendt, 1856) and Margattea Shelford, 1911 sp. presence in Danish amber are insufficient.

We describe two larvae of Raphidioptera probably belonging to different genera of Raphidiidae, the first recorded from middle Eocene Sakhalinian amber and late Eocene Rovno amber. The Sakhalinian larva is the first confirmed representative of Raphidioptera from the Cenozoic of Asia, and most probably the oldest larvae of an extant family of the order. The Rovno amber larva is the first European Cenozoic immature raphidiopteran found outside of Russo-Scandia. The terrestrial insect assemblage of the Sakhalinian amber forest is discussed, including snakeflies. An abundance of aphids and rarity of ants distinguishes this assemblage from other Cenozoic amber faunas.

The new species of the genus Duchailluia Rehn, 1933, D. ivindo sp. nov., is described from Gabon. The genus Distylopyga Bey-Bienko, 1965 is restored from synonymy with Duchailluia. Distylopyga beccalonii sp. nov. from Thailand is described. Neostylopyga yemenica (Bey-Bienko, 1969) comb. nov. is transferred from Duchailluia. A detailed morphological descriptions of the new species are given, N. yemenica is redescribed inclusive male genitalia. The male genitalia of N. yemenica is described for the first time. The subfamily Duchailluiinae Roth, 2003 synonymized with Blattinae Latreille, 1810.

New cockroach species from South India (Aptera brindlei sp.nov., Rhabdoblattella alexeevi sp.nov., R. euptera sp.nov., Morphna indica sp.nov.) and Sri Lanka (Placoblatta beybienkoi sp.nov., Morphna srilankensis sp.nov.) are described. The genus Rhabdoblattella Anisyutkin, 2000 is re-diagnosed. A revised key to the genera of Epilamprinae from South India and Sri Lanka and detailed morphological descriptions of new species are provided. The structure of the female genital complex of Aptera fusca (Thunberg, 1784) is described for the first time. Possible biogeographical connections of the cockroach fauna of Indian subcontinent and the phylogenetic significance of the right phallomere are briefly discussed.

The new genus Indoapterolampra, gen. nov. and two new species (I. rugosiuscula sp. nov. and Morphna lucida sp. nov.) are described. Rhabdoblatta praecipua (Walker, 1868) is removed from the synonymy with 'Polyzosteria' terranea Walker, 1868. The latter species is considered Epilamprinae gen. sp. The lectotype of Phoraspis (Thorax) porcellana Saussure, 1862 is designated. A key for the genera of Epilamprinae from South India and Sri Lanka is provided. Detailed morphological descriptions of the studied taxa are given. The structure of the male genitalia of I. rugosiuscula sp. nov., M. lucida sp. nov., M. plana (Brunner von Wattenwyl, 1865), M. decolyi (Bolivar, 1897) and R. praecipua and that of the female genital complex of M. decolyi, P. (T.) porcellana and Phlebonotus anomalus (Saussure, 1863) are described for the first time. Some aspects of the cockroach evolution are briefly discussed.

A new earwig of the Malagasy genus Mesodiplatys stat. nov., M. venado sp. nov. (Dermaptera: Diplatyidae) is described from Peru (Departament Junin, Satipo Province). The diagnosis and composition of the genus Mesodiplatys stat. nov. are discussed. A detailed morphological description of the new species is given. The possible biogeographical significance of the find as evidence of link between South American and Malagasy fauna is briefly considered.
