A checklist of the world species of Limnichidae (35 genera, 345 species) and Lutrochidae (1 genus, 11 species) is presented. The author, year of publication and page number, synonyms, distribution by country, and a terminal bibliography are given for each genus and species. Biological information is also reviewed.
The only published checklist of the Hydradephaga from the Maryland area is Ulke (1902) who records 65 species from the District of Columbia. The present paper lists 121 species as occurring in Maryland. Comparable lists for other states are as follows: Young (1954), 120 species from Florida; Folkerts (1978), 120 species from New York; and Brigham (1982) and Sanderson (1982), 115 species from North and South Carolina. Some of the identifications are questionable until generic revisions are completed. This is especially true of Hydroporus and Gyrinus.
The species of the genus Alurnus Fabricius (Coleoptera: Chrysomelidae: Cassidinae) are reviewed. Twentythree species are recognized as valid. Alurnus bicolor from Colombia and A. crenatus from Bolivia are described as new species. Alurnus costalis dallieri Pic is elevated to full species status. Lectotypes are designated for A. humeralis Rosenberg, A. mutabilis Waterhouse, and A. salvini Baly. The species are redescribed and illustrated, and a key to the species is presented.
A revision of the genus Acentroptera Guérin-Méneville, 1844 (Coleoptera: Chrysomelidae: Cassidinae)
(2014)
The species of the genus Acentroptera Guérin-Méneville, 1844 are revised. Thirteen species are treated as valid and are illustrated. A neotype is designated for A. tessellata Baly. Acentroptera maculata Pic from Brazil and A. rubronotata Pic from Brazil are treated as incertae sedis. Acentroptera bita n. sp. and A. lineata n. sp. both from Panama are described as new. A key to the 13 treated species is presented. Five species appear to be associated with bromeliads (Bromeliaceae).
A key to the subgenera of Anisostena Weise is presented. Apostena new subgenus is erected from angustata Pic and missionensis Monros & Viana; bondari Maulik and breveapicalis Pic are transferred from Anisostena s. str. to Anisostena (Neostena). Keys to the species of the subgenera Neostena and Aposostena are presented.
