The Afrotropical ponerine ant genus Loboponera is newly described. It contains 7 new species and one species previously regarded as a member of Pachycondyla F. Smith (L. nasica (Santschi) comb. n.). The relationships of Loboponera within the Plectroctena genus group and tribe Ponerini are discussed and apomorphy-based diagnoses are provided for all taxa. An identification key and descriptions are provided for the workers of Loboponera. Revised keys and taxonomic synopses are given for Psalidomyrmex (6 species) and Plectroctena (15 species); within the latter Pl. gabonensis is a new junior synonym of Pl. minor.

The Asthenini (Geometridae, Larentiinae) are reviewed at the generic level. Critical examination of the composition of the tribe has led to the recognition of 18 genera, with the species ‘Chalyboclydon’ flexilinea Warren unplaced. Species are listed under all of the genera identified as Asthenini; their broad distribution is noted; and remarks on peculiarities are noted. Seven other genera that have been associated with the tribe are also considered, and reasons for the exclusion are given. A lectotype is designated for the non-asthenine species Chalyboclydon marginata Warren.

Fieldwork in 2000–2001 in the upper Amazon basin and the Andes (Ecuador) has yielded 16 new species of Nepticulidae, described here. Four genera are represented: Enteucha Meyrick (two species: E. acuta, E. guajavae), Stigmella Schrank (four species: S. montanotropica, S. nubimontana, S. rubeta, S. austroamericana), Fomoria Beirne (two species: F. repanda, F. tabulosa) and Acalyptris Meyrick (8 species: A. ecuadoriana, A. onorei, A. basihastatus, A. pseudohastatus, A. articulosus, A. rotundus, A. amazonius, A. insolentis); the authors of all new taxa are Puplesis & Diškus. Larvae have been reared from three genera of different plant families: Psidium (Myrtaceae), Acalypha (Euphorbiaceae) and Rubus (Rosaceae). The adult moths of all 16 species treated are illustrated in black and white, with line drawings of genitalia and, for four species, drawings of leaf-mines.

Fieldwork in 2000–2001 has added substantially to our knowledge of the Nepticulidae of the upper Amazon basin and the Andes and increased the number of species known from the Neotropical Region from 58 to 74. Two species – Manoneura basidactyla (Davis) and Ectoedemia fuscivittata Puplesis & Robinson – are recorded from equatorial America for the first time here and are redescribed, with amplified descriptions and illustrations. A revised checklist of the Neotropical Nepticulidae is given together with an updated distribution map for Central and Southern America. Fomoria latipennata Puplesis & Robinson is transferred to Acalyptris, comb. n. Four new species-groups (Stigmella tiliella-group, S. barbata-group, Fomoria molybditis-group and Acalyptris latipennata-group) are defined. Hostplant data are reviewed and further hostplant genera from which mines or cocoons have been collected are noted. The diversity and distribution of the Neotropical Nepticulidae are discussed.

With the increasing migration of people from Guatemala (where foci of human onchocerciasis exist) to Belize the probability of further introductions of individuals infected with this disease has increased. The present paper provides a comprehensive biosystematic revision of the Simuliidae of Belize, a prerequisite to any future surveys on simuliids if onchocerciasis becomes a public health problem. A key to the adults and pupae of the twelve species collected is provided together with full morphological descriptions of these species, discussions on their taxonomy, and summaries of their distribution and biology. Six new synonyms, a neotype and one lectotype are created. The distribution of Simuliidae in Belize in relation to physical factors is reviewed.
