Meromacrus is a genus of conspicuous syrphids with saprophagous larvae, ranging from the southern United States to Argentina and Chile. However, this genus is in need of a taxonomic revision. Adults reared from larvae collected in Mexico and Peru, and other material available at different institutional collections were examined. Meromacrus cactorum sp. nov., from Peru, Meromacrus yucatense sp. nov., from Mexico, their puparia and breeding sites were described. A key to Meromacrus puparia is provided. The holotypes of Meromacrus canusium, Meromacrus gloriosus, Meromacrus laconicus and Meromacrus melmoth were also examined. The name Meromacrus draco is proposed as a junior synonym of M. gloriosus. Larvae of M. cactorum sp. nov. were found in decaying columnar cacti in Peru, while those of M. yucatense sp. nov. in a rot-hole of a Ceiba pentandra stump. Obtained results on both taxonomy and biology of these species serve as a first step towards a revision of the entire genus.

Perdita subgenus Heteroperdita Timberlake, a distinctive subgenus of 22 species from the southwestern United States and adjacent Mexico, all specialists on Tiquilia (Boraginaceae), is revised. Nine new species are described: Perdita (Heteroperdita) desdemona Portman, sp. n., P. (H.) exusta Portman & Griswold, sp. n., P. (H.) hippolyta Portman & Griswold, sp. n. (male previously incorrectly described as P. pilonotata Timberlake), P. (H.) hooki Portman & Neff, sp. n., P. (H.) nuttalliae Portman, sp. n., P. (H.) prodigiosa Portman & Griswold, sp. n., P. (H.) sycorax Portman, sp. n., P. (H.) titania Portman & Griswold, sp. n., and P. (H.) yanegai Portman, sp. n. The following sexes are associated and described for the first time: the male of P. (H.) frontalis Timberlake, 1968, the female of P. (H.) optiva Timberlake, 1954, and the true male of P. (H.) pilonotata Timberlake, 1980. Perdita (H.) fasciatella Timberlake, 1980 is proposed as a junior synonym of P. (H.) sexfasciata Timberlake, 1954. A neotype is designated for P. (H.) pilonotata Timberlake, 1980. Two species in particular, P. prodigiosa and P. pilonotata, are sexually dimorphic with distinctive ant-like males. Information is presented on floral relationships, phenology, and geographic distribution. Identification keys for males and females are provided.

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.

Neoceratitis is revised to include six species. N. albiseta, from Madagascar, is described as new. Trirhithrum lycii var. min-imum Bezzi, 1924 is a junior synonym of Ceratitis lycii Coquillett, 1901, new synonym. All known and suspected hostassociations are within the family Solanaceae, with one species (N. cyanescens) infesting tomatoes and several species ofSolanum, whereas the other species with known hosts are associated with Lycium spp. Neoceratitis is probably similar toTrirhithrum Bezzi and particularly to the little known Paratrirhithrum Shiraki. Redescriptions (description in the case of the new species) and illustrations are provided for all the species, and a key to all the species is also provided.

The Elachista bedellella Sircom complex is diagnosed and its taxonomy is revised. The female genitalia, when known, are found to be of good diagnostic value in defining species. In the male genitalia there are subtle, yet decipherable interspecific differences in the shape of the juxta and the cornutus that correlate with differences in the outer appearance of different populations. As a result, eight species are recognised, including the following new species: Elachista antonia sp. n. from Greece (Crete), E. slivenica sp. n. from Bulgaria, E. dorinda sp. n. from Turkey, E. versicolora sp. n. from Russia (Transbaikalia) and E. camilla sp. n. from Russia (Kuray). The identity of E. lugdunensis Frey is clarified and it is considered a valid species, and E. coeneni Traugott-Olsen, 1985 is confirmed to be a junior synonym of it. E. bedellella, E. lugdunensis and E. titanella Kaila & Jalava, 1994 (stat. n.) are diagnosed and illustrated.

The species belonging to the Monolepta pallidula species group are revised. Two species are recognized as valid: Monolepta sauteri Chûjô and M. kuroheri Kimoto. Taiwanese populations of Monolepta pallidula (Baly) are a distinct species different from the true M. pallidula. Thus Monolepta gracilipes Chûjô, a junior synonym of M. pallidula from Taiwan, is an available name and should be reinstated. A new species, Monolepta tsoui, is described with delimitation of color variation from its allied species, M. gracilipes. A lectotype is designated for Monolepta gracilipes Chûjô. A key to the species of the species group is provided.

<p>The New Zealand Thomisidae (crab spiders) are represented in New Zealand by two subfamilies (Stephanopinae and Thomisinae) and were used as a model group to test two competing theories on the origins of the New Zealand spider fauna. The New Zealand thomisids are also given their first full taxonomic revision. The two origin models essentially represent species radiations following recent dispersal or ancient vicariance events. Modern distribution data suggested that the stephanopines are poor dispersers and may provide evidence demonstrating a long period of separation from Australia; while in contrast, thomisines are known to be excellent dispersers. Maximum Likelihood and Bayesian analyses of cytochrome c suboxidase subunit I (COI), 28S ribosomal RNA (28S), histone H3 (H3), NADH dehyrogenase 1 (ND1) data and a combined genetic dataset was undertaken. Results indicate New Zealand stephanopines and thomisines form distinct endemic groups separate from sampled Australian species and appear to have separated from them around 5-6 million years ago. Additionally, genetic data from this study showed i) colour variations are not indicative of cryptic species; ii) previously described species are genetically distinct; iii) several suspected new species are also genetically distinct; iv) the relatively recent establishment of two Australian stephanopines and the occurrence of similar COI haplotypes in disjunct locations suggest that the dispersal ability of stephanopines is greater than previously thought and that radiation following colonization from Australia is a plausible explanation for the current diversity of the New Zealand thomisid biota. The taxonomic revision raises the number of described species from eight to eleven based on a combination of morphological and genetic data. In the stephanopines, Bryantymella Gen. nov. is erected to contain the type species Bryantymella angularis (Urquhart, 1885) comb. nov. as well as B. angulata (Urquhart, 1885) comb. nov., B. thorini sp. nov. and B. brevirostris sp. nov. Two Australian species, Sidymella longipes (Koch, 1874) and S. trapezia (Koch, 1874), are also recorded for New Zealand. Sidymella benhami (Hogg, 1910) is considered to be a junior synonym of Bryantymella angulata (Urquhart, 1885). In the thomisines, all species are now included in the previously monotypic genus Cymbachina Bryant, 1933. The genus now encompasses the type species C. albobrunnea (Urquhart, 1893), C. ambara (Urquhart, 1885) comb. nov., C. albolimbata (L. Koch, 1893) comb. nov., C. sphaeroides (Urquhart, 1885) comb. nov. and D. urquharti sp. nov. Synema suteri Dahl, 1907 is regarded as a junior synonym of C. ambara (L. Koch 1893). All previously described species are redescribed to a modern standard and sexes for some species are described for the first time. Three new species are described. Photographs of adults and diagnostic genitalic characters are included, as are diagnostic keys and updated synonymic, geographic and biological information. Overall, this study indicates that New Zealand thomisids appear to have split from their Australian relatives some 5-6 million years ago and taken in concert with the recent establishment of two Australian stephanopine species, it appears that dispersal to New Zealand by Australian colonists and subsequent radiation into endemic New Zealand forms is a plausible explanation for the current state of the fauna. Genetic and morphological data are mutually supporting and in concert have helped inform the first taxonomic revision ever undertaken for this family in New Zealand.</p>

The present study represents a taxonomic revision of the Pheidole sikorae species group from Madagascar. Forty-four members of this group are recognised and described, and an illustrated identification key to this group is also presented. One species is raised to species level: P. litigiosa Forel, 1892 stat. nov.Pheidole veteratrix angustinoda Forel, 1892 syn. nov. is proposed as a junior synonym of Pheidole veteratrix Forel, 1891. Worker castes are also described and lectotypes designated for P. litigiosa Forel, 1892, P. sikorae Forel, 1891, and P. veteratrix Forel, 1891. The following 41 new species are described: P. alinasp. nov., P. ambohimangasp. nov., P. analavelonasp. nov., P. andohahelasp. nov., P. anomalasp. nov., P. anosyennesp. nov., P. antranohofasp. nov., P. beankasp. nov., P. befotakasp. nov., P. dasossp. nov., P. flavominutasp. nov., P. gracilissp. nov., P. habokasp. nov., P. havoanasp. nov., P. hazosp. nov., P. itremosp. nov., P. joffrevillesp. nov., P. kelysp. nov., P. lavasoasp. nov., P. mahamavosp. nov., P. maintysp. nov., P. mamiratrasp. nov., P. mananteninasp. nov., P. masoandrosp. nov., P. mavohavoanasp. nov., P. midongysp. nov., P. mikrossp. nov., P. mivorysp. nov., P. nitidobrunasp. nov., P. parvulasp. nov., P. parvulogibbasp. nov., P. reniranosp. nov., P. savasp. nov., P. sofiasp. nov., P. sparsasp. nov., P. tamponysp. nov., P. trichotossp. nov., P. tsaravonianasp. nov., P. vadumsp. nov., P. volontanysp. nov., and P. vonysp. nov. At present, there are 109 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase with upcoming taxonomic revisions of the species groups not revised in this study.
