The Neotropical genus Cassidinoma Hincks is revised. A new synonymy is proposed: Cassidinoma denticulata (Boheman) = Cassidinoma monstrosa (Boheman) syn. n. The diagnosis, description, distribution, and biology are reviewed, and new distribution records are included. Illustrations of the habitus of adult and morphological structures are also added.

A new tortoise beetle species, Cyrtonota abrili, is described from the Antioquia and Caldas departments in Colombia. New faunistic data are provided for 87 species, including 16 new additions to the country's fauna. A checklist of the known 238 species of tortoise beetles recorded from Colombia is given.

The genus Herminella Spaeth from southern Africa is revised. It comprises four species: Herminella liliputana Spaeth and H. marshalli Spaeth are redescribed and two species are described as new-H. quadrimaculata from South Africa and H. flavocostata from Nambia and South Africa. A new related genus and species Hermosacantha madagascarica from Madagascar is described. Members of both genera belo...

Notosacantha bertounesquei sp. nov. is described from Kerala state in southern India. This new species belongs to the group of two large species hitherto known only from Sri Lanka. Checklist and key to Notosacantha species of Sri Lanka and southern India are provided.

Species richness and abundance of seven Plagiometriona species on their host plants were studied along a single trail in the mountainous Serra dos Órgãos National Park in the State of Rio de Janeiro, Brazil. Six sites were chosen along an altitudinal gradient ranging from 1300 m to 2050 m, where all Solanaceae host plants were inspected in search of adults every two months from June 2006 to Jun...

Aspidimorpha (Aspidimorpha) wagneri sp. nov. is described from Uganda. This species belongs to the nominotypical subgenus, together with several African species that are closely related to A. mutata Boheman, 1854. Its relative position within the genus is discussed.

A new subgenus and species, Charidotella (Chapadacassis subgen. n.) paradoxasp. n. is described and figured from the Chapada plateau in Mato Grosso, Brazil. Subgenera of Charidotella Weise, 1896 are listed, supplemented with basic data, diagnostic table, and a key is proposed. Based on a study of respective type material following new combinations are proposed: Charidotella (Philaspis) stulta (...

Survey work from 1992-2001 identified 139 species of hispines at the lowland part of La Selva Biological Station, Costa Rica. The tribe Cephaloleiini was the most speciose with 58 species (41.7%) followed by the Chalepini with 55 (39.5%). The fauna is most closely related to that in South America but with some genera which are more speciose in the Nearctic Region. Plant associations are known f...

Immatures of Mesomphalia gibbosa (Fabricius, 1781) and Mesomphalia turrita (Illiger, 1801) (Coleoptera, Chrysomelidae, Cassidinae, Mesomphaliini) are described based on specimen collections from Rio de Janeiro state, Brazil. The last-instar larva and pupal exuviae of M. gibbosa (Fabricius, 1781) and the eggs, first-instar larva, and pupa of M. turrita (Illiger, 1801) are described, photographed...
