“…In sub-Saharan Africa, in particular, 86 flea beetle genera are recorded of which about 66% are endemic (Biondi 2017, Biondi & D'Alessandro 2010a, 2010b, 2011, 2013a, 2013b, 2016, 2017, 2018, Dö-berl 2010, 2014, 2017, Biondi et al 2017.…”

In this paper Chaetocnema adamastori sp. nov. and C. saldanhai sp. nov., both from Western Cape Province (Republic of South Africa), are described. The two new species are closely related with C. audisiana Biondi and C. capensis Bryant, respectively. Micrographs of diagnostic characters, including male and female genitalia, are supplied. Ecological data for each species, including habitat preference, host plant and phenology, are also reported.

Aim The areal distributions of Chaetocnema species in the Afrotropical Region have been analysed with the aims of determining the distribution patterns (chorotypes) and identifying the most important areas of endemism for this flea beetle genus in sub‐Saharan Africa. Location Data were collected in sub‐Saharan Africa, including Madagascar. Methods The Afrotropical Region was divided into 103 5° quadrats (operative geographical units, or OGUs). A presence–absence matrix of the Afrotropical Chaetocnema species in the OGUs was analysed by cluster analysis (Baroni Urbani & Buser index and the WPGMA clustering method) to generate distribution pattern data based on similarity of distribution. The most important areas of endemism were identified by parsimony analysis of endemicity. Results The general distribution of Chaetocnema in the Afrotropical Region was found to be associated with moist environments and montane grasslands. Most species exhibit restricted geographical ranges. Cluster analysis revealed 120 spatial distributions that can be grouped into 13 distinct distribution patterns (chorotypes). The most important areas of endemism for Chaetocnema in sub‐Saharan Africa according to the present parsimony analysis of endemicity are: (1) central and eastern Madagascar [endemicity rate (ER) = 61.1%], (2) Western Cape Province (ER = 36.4%), (3) southern Drakensberg (ER = 26.7%), (4) the Shaba Region (ER = 16.7%), and (5) the North‐Kivu Region (ER = 5.0%). Main conclusions There are 123 known species of Chaetocnema in the Afrotropical Region, more than in any other zoogeographical region. About 91% of the species are endemic and they generally exhibit a restricted and often very localized geographical range. The remaining 9% of the species are represented by seven species that also inhabit northern Africa and/or the Arabian peninsula (C. bilunulata Demaison, C. ganganensis Bechyné, C. ljuba Bechyné, C. pulla Chapuis, C. tarsalis Wollaston, and C. wollastoni Baly), three species that widely inhabit the Palaearctic Region (C. conducta (Motschulsky), C. schlaeflini (Stierlin), and C. tibialis (Illiger)), and two species that were introduced (C. confinis Crotch, and C. picipes Stephens).

Abstract. This paper consists of an up to date annotated catalogue of the Afrotropical genera of Alticinae (Chrysomelidae), with biogeographical notes on the flea beetle fauna occurring in Sub-Saharan Africa and Madagascar. The following new synonymies are proposed: Eugonotes Jacoby, 1897 (a subgenus of Sanckia Duvivier, 1891) = Brancucciella Medvedev, 1995 syn. n.; Amphimela Chapuis, 1875 = Dibolosoma Jacoby, 1897 syn. n.; Amphimela Chapuis, 1875 = Halticova Fairmaire, 1898 syn. n.; Podagrica Chevrolat, 1837 = Podagrixena Bechyné, 1968 syn. n.; Aphthona Chevrolat, 1837 = Pseudeugonotes Jacoby, 1899 syn. n.; Nisotra Baly, 1864 = Pseudonisotra Bechyné, 1968 syn. n. The following new combinations are proposed: Afrorestia sjostedti (Weise, 1910) comb. n. (from Crepidodera); Bechuana natalensis (Jacoby, 1906) comb. n. (from Ochrosis); Sesquiphaera natalensis (Jacoby, 1906) comb. n. (from Sphaeroderma). The genus Hildenbrandtina Weise, 1910 is trasferred from Galerucinae to Alticinae. New distributional data for many genera in the Afrotropical region is provided. 401genera transferred to Galerucinae or to genus-group names that are unavailable.In addition to author and date of publication, each genusgroup name is accompanied by: (a) synonymies, exclusively those for the Afrotropical region; (b) bibliographic references, including the original description and other important taxonomical contributions; (c) type species, including the method of species assignment; (d) geographic distribution in the Afrotropical region (cf. Graf & Cummings, 2007) and other zoogeographical regions (cf. Sclater, 1858); (e) ecological remarks, mainly host-plants and/or habitat preferences; (f) notes, including the number of Afrotropical species and important taxonomical news.The type material examined for this study is preserved in the following institutions: BAQ -collection of the author, Dipartimento di Scienze Ambientali, University of L'Aquila, Italy; BMNH -The Natural History Museum, London, United Kingdom;
