- article, model:article, and TEXT
- Subject:
- Taxonomy, Afrotropical region, Chrysomelidae, Alticinae, Galerucinae, flea beetle genera, catalogue, synonymies, and new combinations
- 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.

3. Pepila Weise: Taxonomic identity of the genus and revision of the megalopoides species-group, and description of two new species from Australia (Coleoptera: Chrysomelidae: Alticinae)
- Creator:
- Biondi, Maurizio and D'alessandro, Paola
- Type:
- article, model:article, and TEXT
- Subject:
- Coleoptera, Chrysomelidae, Pepila, Australia, taxonomy, new species, and new combinations
- Language:
- English
- Description:
- In this paper some taxonomic observations on the Australian flea beetle genus Pepila Weise, 1923 are reported. The following species are transferred to the genus Pepila and lectotypes for them designated: Chaetocnema carinata Baly, 1877; Plectroscelis crassipennis Blackburn, 1896; Chaetocnema fuscomaculata Baly, 1877; Plectroscelis hypocrita Blackburn, 1896; Chaetocnema laticeps Baly, 1877; Plectroscelis meyricki Blackburn, 1896; Dibolia ochracea Waterhouse, 1838; Plectroscelis pallidior Blackburn, 1896; Dibolia pygmaea Waterhouse, 1838; Plectroscelis quadraticollis Blackburn, 1896; Chaetocnema submetallescens Baly, 1877; Plectroscelis tumbyensis Blackburn, 1896; Chaetocnema waterhousei Baly, 1877. The synonymy of Chaetocnema submetallescens Baly, 1877 with Plectroscelis longior Blackburn, 1896 is proposed. In addition, the megalopoides species-group, including P. megalopoides Weise, 1923, P. uptoni n.sp., and P. longifallica n.sp., is analyzed.

4. Revision of the species of Chaetocnema from Madagascar (Coleoptera: Chrysomelidae: Alticinae)
- Creator:
- Biondi, Maurizio
- Type:
- article, model:article, and TEXT
- Subject:
- Coleoptera, Chrysomelidae, Chaetocnema, Madagascar, taxonomy, biogeography, and key
- Language:
- English
- Description:
- The species of flea beetles of the genus Chaetocnema Stephens, 1831 occurring in Madagascar are revised. Four new species (C. cachani, C. hygrophila, C. malgascia and C. orophila) are described and five species (C. bamakoensis Bechyné C. confinis Crotch, C. fuscipennis Scherer, C. ganganensis Bechyné and C. picipes Stephens) are added to the Madagascar fauna. The following new synonymies are proposed: C. wollastoni Baly, 1877 = C. fraterna Harold, 1879 syn. nov. = C. monomorpha Bechyné, 1964 syn. nov.; C. pulla Chapuis, 1879 = C. tantilla Weise, 1910 syn. nov.; C. bilunulata Demaison, 1902 = C. sylvia Bechyné, 1964 syn. nov.; C. vadoni Bechyné, 1948 = C. alaotrensis Bechyné, 1964 syn. nov.; C. gregaria Weise, 1910 = C. insularis Weise, 1910 syn. nov. Lectotypes are designated for C. gregaria Weise, 1910, C. insularis Weise, 1910, C. similis Weise, 1910 and C. tantilla Weise, 1910. A key to all the species is presented. Line drawings of male and female genitalia of all the species are included. Ecological and brief zoogeographical data on some species are given.

- počítač and online zdroj
- Type:
- model:article and TEXT
- Subject:
- Coleoptera, Chrysomelidae, Galerucinae, Alticini, Angulaphthona, Afrotropical region, Arabian Peninsula, Sri Lanka, new combination, taxonomy, revision, and new species
- Language:
- English
- Description:
- A revision of the genus Angulaphthona Bechyné, 1960 is provided, with a description of Angulaphthona confusa sp. n. from the Democratic Republic of Congo, and A. rossii sp. n. from Sierra Leone. The following synonymies are proposed: Angulaphthona latipennis (Pic, 1921) = A. latipennis zambeziensis (Bechyné, 1959) syn. n. and Angulaphthona pelengensis Bechyné, 1960 = A. exalta Bechyné, 1960 syn. n. The precedence of the name pelengensis is discussed. Angulaphthona violaceomicans (Chen, 1936) comb. n. (transferred from Aphthona) from Sri Lanka is established, and some hypotheses to explain the presence of the genus outside Africa are put forward. A key to the seven known species is supplied, with microphotographs of diagnostic characters, including male and female genitalia.

6. Taxonomical revision of the Longitarsus capensis species-group: An example of Mediterranean-southern African disjunct distributions (Coleoptera: Chrysomelidae)
- Creator:
- Biondi, Maurizio and D'Alessandro, Paola
- Type:
- article, model:article, and TEXT
- Subject:
- Chrysomelidae, Alticinae, Boraginaceae, Afrotropical region, Mediterranean area, new species, and disjunct distribution
- Language:
- English
- 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.
