Description:
Afroaltica subaptera, a new genus and species of flea beetles (Chrysomelidae: Alticinae) from the eastern regions of southern Africa (Eastern Transvaal and Kwazulu-Natal), is described. Afroaltica gen. n. shows some similarities with the genus Dibolia Latreille, 1829 but it is easily distinguishable mainly by the simple-shaped apical spur of hind tibiae, not bifid. External habitus, scanning electronic micrographs of particular morphological features and line drawings of metafemoral spring and male and female genitalia of the new taxon are provided.

Subject:

Language:
English
Description:
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.

Description:
Southern-African Longitarsus capensis species-group, which is closely related to the Mediterranean anchusae species-group is revised. L. capensis species-group includes 15 species, 8 of which are new to science: Longitarsus capensis Baly, 1877, L. cedarbergensis Biondi, 1999, L. luctuosus Biondi, 1999, L. lugubris Biondi, 1999, L. melanicus Biondi, 1999, L. neseri Biondi, 1999, L. transvaalensis Biondi, 1999, L. afromeridionalis sp.n., L. debiasei sp.n., L. grobbelaariae sp.n., L. hexrivierbergensis sp.n., L. malherbei sp.n., L. piketbergensis sp.n., L. rouxi sp.n., and L. sudafricanus sp.n. A key to all the species is presented as well as line drawings of male and female genitalia, scanning electron micrographs of some diagnostic morphological characters, and auto-ecological and zoogeographical data. Relationships within the capensis-group, and between the anchusae and capensis-group are better defined and hypotheses explaining the separate distributions of Mediterranean and south African anchusae and capensis species-groups proposed. Finally, the host-plant shift from native Lobostemon spp. to the introduced plant Echium plantagineum L. shown by some species of the capensis group is also discussed.
