The paper presents a description of the hitherto unknown larva of Ecclisopteryx malickyi Moretti 1991. Information for the identification of this species is given, and the most important diagnostic features are illustrated. Some zoogeographical and ecological notes are added. Furthermore, larval morphology of the whole genus is discussed and differentiating characters are given.

A new wingless ground beetle, Calathus (Calathus) jakupicensis nov. sp. (type locality: subalpine zone of Karadzica Mt., Jakupica Massif, Macedonia) is described. The diagnostic characters of the species are defi ned and illustrated, making possible its recognition. The new species is eastern vicariant and adelphotaxon of C. (C.) ravasinii J. MÜLLER.

Strelkovimermis spiculatus n. sp. (Mermithidae: Nematoda), a parasite of the mosquito Aedes albifasciatus Mac. in Argentina, is described. Diagnostic characters of this species include a ventrally shifted mouth opening and spicules fused at the tips. The mermithid has been reared on Culex pipiens L. larvae in the laboratory.

Male and female adults of Culex (Culex) articularis Philippi are redescribed, and the 4th-instar larva and pupa are described and illustrated for the first time. Culex articularis is compared with other species of the subgenus Culex. Illustrations of diagnostic characters of the female, male genitalia, 4th-instar larva, and pupa are also provided.

The aim of this paper is to describe and illustrate a new species of Aclastus with dimorphic females and to provide the diagnostic characters to distinguish it from Holarctic species of the genus. In addition, we provide data on the habitat and phenology of the species.

A taxonomic study of the genus Homalota Mannerheim in Korea is presented. Five species are recognized, one of which, Homalotaserrata (Assing), comb. n. is transferred from Anomognathus Solier. Homalotafraterna (Sharp), Homalotamikado Likovský, Homalotasauteri Bernhauer, and Homalotaserrata are newly added to the Korean fauna. A key, descriptions, and illustrations of the diagnostic characters a...

Two new species of the genera Epectinaspis Blanchard and Strigoderma Burmeister from Central America, E. costaricensis new species and S. ngabe new species, are described and illustrated. For each species and their closest congeners, their diagnostic characters are discussed and the taxonomic keys for their determination are modified.

Deltochilum (Deltohyboma) gigante sp. nov., from Parque Nacional Las Cuevas de los Guácharos, Huila, Colombia is described based on differences in external and genital morphology. Its diagnostic characters are provided and illustrated. Lectotype and paralectotypes for D. spinipes, a close relative to the new species, are designated.

Four new species of Tambinia Stål (Hemiptera: Fulgoromorpha: Tropiduchidae), Tambinia conussp. n. (Papua New Guinea), Tambinia maculasp. n. (Malaysia: Borneo), Tambinia robustocarinasp. n. (Malaysia: Sabah) and Tambinia sexmaculatasp. n. (Australia: Kuranda) are described and illustrated from the Pacific region. The diagnostic characters of this genus are redefined. A checklist and a key to the...
