Xestocephalus Van Duzee is among the most common and widespread genera of Cicadellidae in the temperate and tropical regions of the world. In the present study, 205 specimens of the genus Xestocephalus were collected in Thailand, whereas only a single species of the genus was recorded previously using Malaise trap field sampling, studied by comparative morphology. Seventeen species were recognized, including twelve new species: X. binarius sp. nov., X. chrysanthemum sp. nov., X. cowboyocreus sp. nov., X. densprint sp. nov., X. dimiprocessus sp. nov., X. exproiecturus sp. nov., X. gracilus sp. nov., X. limpidissimus sp. nov., X. malleus sp. nov., X. nonattribus sp. nov., X. recipinams sp. nov., and X. tenusis Liang sp. nov. Four species were recorded in Thailand for the first time: Xestocephalus abyssinicus Heller and Linnavuori, Xestocephalus asper Linnavuori, Xestocephalus ishidae Matsumura, and Xestocephalus toroensis Matsumura. Detailed morphological descriptions of all 17 species are given; photographs of external habitus and male genitalia of the species from Thailand are provided. A checklist of species of the genus is also given, and a key to all Thailand Xestocephalus species is also provided.

The diversity of the formicine ant genus Nylanderia is currently underestimated and largely undescribed. This includes the faunas of tropical regions where species richness is typically high. Here, the taxonomy of the West Indian Nylanderia fauna is revised for the first time. Fourteen new species are described, bringing the total number of species known from the region to 22. The new species are: N. bibadia, sp. nov., N. caerula, sp. nov., N. coveri, sp. nov., N. disatra, sp. nov., N. esperanza, sp. nov., N. fuscaspecula, sp. nov., N. lucayana, sp. nov., N. metacista, sp. nov., N. pini, sp. nov., N. semitincta, sp. nov., N. sierra, sp. nov., N. wardi, sp. nov., N. xestonota, sp. nov., and N. zaminyops, sp. nov. There are several introduced species in the region including the globally widespread Old World species N. bourbonica. Other introduced species are N. fulva, N. pubens, N. guatemalensis, and N. steinheili. The following new synonyms are proposed: fulva Mayr 1862 (= fulva cubana Santschi 1930); steinheili Forel 1893 (= steinheili minuta Forel 1893). An identification key is provided for the workers of Nylanderia found in the West Indies. Photomontage images are provided for the worker of each species and when available photomontage and SEM images are provided for males. This work represents another step forward in understanding the diversity of this widespread and commonly encountered ant genus.

The genus Batracomorphus Lewis is the third largest leafhopper genus in the world, with its greatest diversity in the Oriental region. Here, nine species of Batracomorphus, including one new species, are recorded from Shaanxi Province, China, for the first time: B. allionii (Turton), B. clavatus Cai and Shen, B. fletcheri Hu and Dai sp. nov., B. geminatus (Li and Wang), B. juno Knight, B. lateprocessus Li and Wang, B. lunatus Cai and He, B. subfuscus (Li and Wang) and B. pandarus Knight. Among them, B. juno Knight is recorded from China for the first time. One new synonym is revealed: B.nigromarginattus Cai and Shen, 1999 is a junior synonym of B. subfuscus (Li and Wang, 1993). All taxa are described, and photographs of male genitalia are given based on observations of specimens from Qinling Mountain in Shaanxi of China. A key to the species found in Qinling Mountain of Shaanxi is also provided.

The world species of Ooderella Ashmead, 1896 are revised. Characterization of the genus is based primarily on females, but for the first time males are associated with females through collecting events and described for four species. Putative generic features of males as well as morphological limits of both sexes are discussed, as are possible infrageneric relationships. Previously consisting of a single species from South America, Ooderella smithii Ashmead (♀, ♂), 18 new species are described from the Neotropical, Nearctic and Afrotropical regions, including one from the Nearctic region [O. americana n. sp. (♀)], 5 from the Afrotropical region [O. botswanae n. sp. (♀), O. capensis n. sp. (♀), O. gymnosoma n. sp. (♀), O. kenyaensis n. sp. (♀), and O. platyscapus n. sp. (♀, ♂)], and 12 from the Neotropical region [(O. ambigua n. sp. (♀), O. flavida n. sp. (♀), O. hansoni n. sp. (♀), O. hyalipleura n. sp. (♀), O. melanosceles n. sp. (♀), O. microptera n. sp. (♀), O. reticulifrons n. sp. (♀), O. setosa n. sp. (♀, ♂), O. speculifrons n. sp. (♀), O. spinositegula n. sp. (♀, ♂), O. stenoptera n. sp. (♀), and O. thegalea n. sp. (♀)]. The species are keyed, described, illustrated through macrophotography, and their distributions mapped.

Quantitative attemps to assess species diversity in the absence of a robust taxonomy are questioned. In addition, the sampling methods may be a major source of uncertainty, as illustrated in a commented biodiversity study of the Coleoptera of Sabah. The Sabah members of the staphylinid genus Baeocera Erichson are reviewed and keyed, the following new species are described: B. omnigena Löbl sp. nov., B. rudis Löbl sp. nov., B. secreta Löbl sp. nov., B. sedata Löbl sp. nov., B. segregata Löbl sp. nov., B. seiugata Löbl sp. nov., B. semirufa Löbl sp. nov. Baeocera barbara Löbl, B. obliqua (Löbl), B. rufula (Löbl) and B. serendibensis (Löbl) are reported for the first time from Malaysia, B. doriae (Pic) and B. sarawakensis Löbl are new to Sabah and B. kinabalua Löbl is new to Sarawak. Key words: biodiversity, trends, taxonomy, insects, shining fungus beetles, Borneo

The morphology of the genus Scapheremaeus Berlese, 1910 is reviewed and characters of taxonomic utility delineated. Based on the morphological review, some 13 species-groups are outlined based on major morphotypes. There are two main categories: i) species that have a complete circumdorsal scissure with plicate microsculpture on the circumnotogastral plate and strongly contrasting microsculpture (foveolae, ridges or tubercles) on the centrodorsal plate (plicate species-groups), and ii) species with the circumdorsal scissure complete, incomplete or absent but with little or no contrast in microsculpture between the central and lateral regions: typically both regions foveolate or reticulate (non- plicate species-groups). A catalogue of world species of Scapheremaeus is provided. Scapheremaeus petrophagus (Banks, 1906) is not a Scapheremaeus but belongs to an undetermined genus in the Ameronothroidea. Cymbaeremaeus cyclops Oudemans, 1915 is recombined to Scapheremaeus. Five new species are described (S. angusi sp. nov., S. cheloniella sp. nov., S. ewani sp. nov., S. lambieae sp. nov., and S. pulleni sp. nov.) from soil and litter habitats in semi-arid Mallee eucalypt vegetation at Bookmark Biosphere Reserve, South Australia. These are the first members of the genus Scapheremaeus to be described from Australia, though undescribed species have been recorded previously. All the new species are morphologically closely-related and belong to a single species-group: Carinatus.

The Neotropical genus Pentacalia Cass. (Compositae, Senecioneae) is distributed from southern Mexico to northwestern Argentina, plus two disjunct species that thrive in Brazil. Most species diversity occurs in the montane forests of Colombia, Ecuador, and Peru. It comprises scandent woody plants characterized by displaying alternate leaves (opposite in three species), involucres with supplementary bracts, usually yellow ray florets (when present), sagittate to caudate anther bases, and truncate to obtuse style branches with a crown of sweeping trichomes (sometimes with a tuft of longer trichomes, but not strictly penicillate). The Bolivian species were revised for the first time by Cabrera (1985), who treated the group under Senecio L. sect. Streptothamni Greenm. Because of the subsequent addition of new species and the need of taxonomic arrangements, an updated synopsis of the genus recognizing 18 species is presented. The names P. brittoniana (Hieron.) Cuatrec. and P. miguelii (Cuatrec.) Cuatrec. are synonymized with P. psidiifolia (Rusby) Cuatrec., as well as P. inquisiviensis H. Rob. & Cuatrec. with P. cardenasii (Cuatrec.) Cuatrec. and P. sailapatensis (Cuatrec.) Cuatrec. with P. urubambensis (Cabrera) Cuatrec. Seven names are lectotypified and an epitype is designated for the name P. zongoensis (Cabrera) J. Calvo. The new species P. viburnifolia J. Calvo & A. Fuentes is described. Revised nomenclature, succinct descriptions, taxonomic discussions, lists of specimens examined, and distribution maps are provided for all accepted species, in addition to an identification key. Pictures of living plants are also presented for eight species.
