The caddisfly (Trichoptera) family Calamoceratidae was first established by Ulmer (1906). It includes eight well defined extant genera in two subfamilies, Anisocentropodinae Lestage, 1936 and Calamoceratinae Ulmer,1905, with a total of 175 species worldwide (Morse 2006). Although the family is cosmopolitan, two genera, Banyallarga Navas, 1916 and Phylloicus Muller, 1880, are endemic to the Neotropics (Flint et al.1999, Prather 2003, 2004, Holzenthal et al. 2007). Anisocentropus McLachlan, 1863, the only genus in the Anisocentropodinae, and Phylloicus are the largest in the family, each with 60 species, with most of the former from the Australasian and Oriental regions (Morse 2006). Anisocentropus has five species from the Afrotropical region (Myers et al. 2005, Morse 2006). Of these, A. unsambarensis Ulmer, 1908 is widespread in the region (Johanson 1992). The morphology and biogeography of the genus have been studied by Neboiss (1980). In a recent report, Ogbogu (2006) described a larva suspected to be that of a species that is related to, but different from A. unsambarensis. Now that successful larval-adult association has been achieved and the species identified to be A. unsambarensis, it becomes imperative to describe the adult highlighting some of the adult diagnostic features which are hitherto not known and may be useful for separating species with particular reference to the Afrotropical fauna. |
