The blister beetle genus Teratolytta, belonging to the tribe Lyttini, is revised and a classification is proposed. Two main sections of the genus - one including five groups of species and the other three groups - are tentatively defined. Four new species from Eastern and Southern Anatolia are described (T. carlae sp. n., T. dvoraki sp. n., T. monticola sp. n., T. taurica sp. n.), and a key to the 17 recognized species is proposed. A diagnosis of the species as well as taxonomic remarks are proposed, and a catalogue of localities is presented. In particular, Teratolytta tricolor (Haag-Rutenberg, 1880) comb. n. is re-established as a distinct species, T. cooensis G. Müller, 1936 is confirmed as a synonym of T. gentilis (Frivaldszky, 1877), T. bytinskii Kaszab, 1957 as a synonym of T. senilis (Abeille de Perrin, 1895), and T. holzschuhi Dvořák, 1983 is proposed as a synonym of T. eylandti Semenow, 1894; some infraspecific forms are referred to the variability of T. gentilis and T. flavipes (Mulsant & Rey, 1858). The first instar larva of T. gentilis is described and figured, and the sexual behaviour of this species is also briefly studied.
The genus Vanniusoides Carvalho & Lorenzato is revised and redescribed, a new species V. clypeatus is described from the Solomon Islands. Redescription of the species V. brevis (Poppius) and a key to the species of the genus are given. Illustrations of dorsal habitus, tarsi and male genitalia of the new species are provided.
A revision of the genus Wakarumbia Bocák, 1999 from Sulawesi is presented. Altogether 10 species are included in the genus Wakarumbia: the type species W. gracilis Bocák, 1999 is redescribed, a new combination of Wakarumbia celebensis (Kleine, 1933) is proposed (originally placed in Protaphes Kleine, 1926) and the following new species are described: Wakarumbia brendelli sp. n., W. brunnescens sp. n., W. flavohumeralis sp. n., W. grandis sp. n., W. nigra sp. n., W. oculata sp. n., W. pallescens sp. n. and W. similis sp. n. The important diagnostic characters are illustrated and all species are keyed. Relationship between species and ecological data are briefly discussed.
Six species are identified in the Iteaphila setosa group [I. arundela sp. n., I. caucasica sp. n., I. italica Loew, 1873, I. kubaniensis sp. n., I. merzi sp. n., I. setosa (Bezzi, 1924)]. This species group is distributed from southern England in the west, through southern Europe and northern Africa, to the Caucasus and Middle Asia (Uzbekistan).
Three new species of Tingidae (Tinginae: Tingini) belonging to the New Caledonian endemic genus Nobarnus Distant are described: N. albiceps, N. nigriceps and N. pilosus, N. signatus (Distant) and N. typicus. Distant are redescribed and the status of the genus is discussed and enlarged to accommodate the new species. A table of the main characters distinguishing species and a key to species are given.
The Oriental helotrephid genus Idiotrephes Lundblad, 1933, is taxonomically revised. Species discrimination is based on male genitalia and female terminalia. Three species groups are recognized. The I. chinai group contains I. chinai Lundblad, 1933 (type species; from Sumatra, Borneo, and West Malaysia) and three newly described species; I. asiaticus sp. n. (from Vietnam, Thailand, and west Malaysia); I. yupae sp. n., and I. polhemusi sp. n. (both from Thailand). The I. maior group contains I. maior Papáček, 1994; I. meszarosi Papáček, 1995 (both from Vietnam), and I. hainanensis sp. n. (from Hainan, China). The I. thai group consists of two newly described species from north and northeast Thailand, I. thai sp. n. and I. shepardi sp. n. In addition, some features of biology and morphology of the ovipositor are also included.
The Oriental leafhopper genus Toba Schmidt is reviewed and placed in the subfamily Stegelytrinae Baker. Its type species, T. fasciculata Schmidt, and a new species T. sandakanensis Wei & Webb, are described with details of the male and female genitalia given for the first time. A related new genus and species, Paratoba longa Wei & Webb, gen. n. and sp. n., are described. The subfamily status and the morphological similarities between these two genera and other taxa are discussed.
The subgenus Gnypetalia Cameron, 1939 is redefined and raised to the genus rank. Eleven valid species are recognised in the genus, six of which are described as new: Gnypetalia armata sp. n. (Solomon Islands), G. cuccodoroi sp. n. (Philippines: Luzon), G. insularis sp. n. (Solomon Islands), G. luzonica sp. n. (Philippines: Luzon, Palawan), G. nitida sp. n. (Indonesia: Sulawesi) and G. penrisseni sp. n. (Malaysia: Sarawak). One new synonym is established: Gnypetalia parva Cameron, 1950 = Ischnopoda (Caliusa) finitima Pace, 1998 syn. n. Five species are given in new combination: Gnypetalia indica (Cameron, 1939) comb. n (= Gnypeta (Gnypetalia) indica), Gnypetalia parva (Cameron, 1950) comb. n. [= Gnypeta (Gnypetalia) parva], Gnypetalia rougemontiana (Pace, 1986) comb. n [= Tachyusa (Caliusa) rougemontiana], Gnypetalia song (Pace, 1990) comb. n. [= Tachyusa (Caliusa) song] and Gnypetalia thoracica (Fauvel, 1879) comb. n. (= Tachyusa thoracica). Lectotype is designated for Gnypeta indica Cameron, 1939. The taxa are diagnosed, keyed and illustrated. The phylogeny of the aleocharine genus Gnypetalia is analysed using cladistic methods. The monophyly of Gnypetalia is confirmed and three major monophyletic species group are recognised.
The Poecilimon ornatus group has an exclusively European distribution and includes the largest species in the genus. A revision of the taxa belonging to this group in Bulgaria and Macedonia (Central and Eastern Balkan Peninsula) is presented. Nine taxa described from Bulgaria are synonymised with 3 previously known species, as follows: Poecilimon ornatus (= P. mistshenkoi marzani, syn. n., P. mistshenkoi tinkae, syn. n., P. mistshenkoi vlachinensis, syn. n.), P. affinis s. str. (= P. mistshenkoi mistshenkoi, syn. n., P. affinis ruenensis, syn. n., P. affinis rilensis, syn. n., P. affinis medimontanus, syn. n., P. harzi, syn. n.) and P. hoelzeli (= P. kisi, syn. n.). The synonymy of P. poecilus with P. affinis and the subspecific status of P. affinis komareki are confirmed. One species, Poecilimon jablanicensis, sp. n., is described as new to science. A tabulated key, lists and maps of all known localities and oscillograms of the songs of all the species in this group are presented. The phylogenetic relationships and evolutionary trends in the Poecilimon ornatus group are discussed.
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.
