The genus Macroderes Westwood, 1842 (Scarabaeidae: Scarabaeinae, tribe incertae sedis) is practically endemic to South Africa with only one species that is found little north in southern Namibia. The ranges of the species are limited to the winter-fall and bimodal biomes of South Africa comprising the regions of Richtersveld as extreme points of its northerly distribution, and extending to the south through Namaqualand to Cape Agulhas. The taxonomy of the genus is revised. Fourteen valid species are recognised and three others are of doubtful validity. Seven new species are described, these are: M. cederbergensis Abdalla & Deschodt, new species, M. tortuosus Abdalla & Scholtz, new species, M. gifboomi Abdalla & Scholtz, new species, M. leipoldti Abdalla & Deschodt, new species, M. oreatus Abdalla & Deschodt, new species, M. porselinus Abdalla, new species, and M. soleiana Abdalla & Deschodt, new species. Macroderes nitidus Harold, 1877 is redescribed and its lectotype is designated. The diagnostic characters as well as an updated geographic distribution of each species are summarised. An updated key of the genus, photographs of habitus, sclerites of internal sac, pronotum, pronotal punctures and elytra also are provided.

The Status

The family Harrimaniidae (Hemichordata: Enteropneusta) is revised on the basis of morphological characters. The number of harrimaniid genera is increased to nine by the addition of Horstia n. gen., Mesoglossus n. gen., Ritteria n. gen. and Saxipendium, a genus previously assigned to the monospecific family Saxipendiidae. The number of species is increased to 34, resulting from the description of five new species from the eastern Pacific — Horstia kincaidi, Mesoglossus intermedius, M. macginitiei, Protoglossus mackiei and Ritteria ambigua. A description is supplied for a sixth harrimaniid species, Stereobalanus willeyi Ritter & Davis, 1904, which previously had the status of a nomen nudum. Four harrimaniids previously assigned to the genus Saccoglossus are transfered to the genus Mesoglossus — M. bournei, M. caraibicus, M. gurneyi and M. pygmaeus, while Saccoglossus borealis is reassigned to the genus Harrimania. Notes on habitat and zoogeography are included for the seven foregoing species and a table of diagnostic characters for existing and new species and a dichotomous key to the enteropneust families and harrimaniid genera are provided. Finally, a phylogenetic hypothesis concerning the Harrimaniidae is postulated, with discussion on the evolution of the group.

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.

A New Species

We present a taxonomic revision of the Colombian Tityus (Archaeotityus) species based on morphological and morphometric evidence. We examined more than 385 specimens and evaluated new and previously used qualitative and quantitative morphological characters. We redescribe the Colombian species and present morphological characters for both sexes and an emended diagnosis for the subgenus Tityus (Archaeotityus). We describe a new species Tityus guane sp. nov. from Santander department, Colombia, Tityus betschi Lourenço 1992 is synonymized with Tityus parvulus Kraepelin, 1914, and Tityus wayuu Rojas-Runjaic & Armas, 2007 is synonymized with Tityus tayrona Lourenço, 1991. We measured 186 specimens and performed a multivariate principal component analysis (PCA) for 34 selected morphometric ratios for each sex. We found that a few morphological ratios support species level distinctions within the Colombian species. We provide updated distributional maps with new records and an identification key for both sexes. Furthermore, we provide an updated checklist for the subgenus and a discussion about the character systems used within Tityus (Archaeotityus). The new morphological characters proposed and the traditional morphometry examined with a PCA are useful for studying Tityus (Archaeotityus) taxonomy.

Two New Species

A complete revision of the world species of the genus Phaenoglyphis Förster, 1869 has been conducted. A total of 25 species of Phaenoglyphis are valid after studying their type material. Two new species are described: Phaenoglyphis belizini sp. n. and Phaenoglyphis palmirae sp. n. Two species are synonymized: P. dolichocera (Cameron, 1889) with P. nigripes (Thomson, 1877) and P. pecki Andrews, 1978 with P. villosa (Hartig, 1841). Phaenoglyphis bangalorensis Kurian, 1953 was considered as incertae sedis. Phaenoglyphis duplocarpentieri (Kieffer, 1904) and P. hedickei Hedicke, 1928 are considered lost. Other three species are discarded as valid species because they are missing important parts without which the species cannot be defined: P. cincta (Hartig, 1841), P. frigidus (Belizin, 1968) and P. repentinus Belizin, 1962. A complete redescription and an illustrative plate are presented. A key to species of the genus Phaenoglyphis is given. Phylogenetic analysis based on morphological characters has been performed.

This paper presents a taxonomic revision of 28 described species of the genus Sirthenea Spinola, 1837 (Hemiptera: Heteroptera: Reduviidae: Peiratinae) distributed in the Afrotropical, Oriental, Palearctic, Oceanian and Australian zoogeographical regions. The following new synonymies are proposed: Sirthenea africana Distant, 1903 = S. rapax Horváth, 1909, syn. nov. = S. leonina Horváth, 1909, syn. nov. = S. bequaerti Schouteden, 1913, syn. nov. = S. leontovitchi Schouteden, 1931, syn. nov.; Sirthenea picescens Reuter, 1887 = S. atrocyanea Horváth, 1909, syn. nov.; S. rodhaini Schouteden, 1913 = S. collarti Schouteden, 1931, syn. nov. = S. angolana Villiers, 1958, syn. nov.; S. flavipes (Stål, 1855) = S. clavata Miller, 1948, syn. nov. = S. bharati Sucheta & Chopra, 1988, syn. nov. = S. koreana Kerzhner & Lee, 1996 syn. nov. = S. melanota Cai & Lu, 1990, syn. nov. = S. nigripes Murugan & Livingstone, 1990, syn. nov.; S. obscura (Stål, 1866) = S. glabra (Walker, 1873), syn. nov. A neotype is designated for S. picescens Reuter, 1887. Three species, S. erythromelas (Walker 1873), S. fulvipennis (Walker, 1873) and S. sobria (Walker, 1873), are excluded from the genus Sirthenea. Two new species from the Oriental Region, S. kali sp. nov. (India) and S. setosa sp. nov. (Malaysia) are described. Identification keys are provided for the subgenera and species from each zoogeographical region treated. Drawings of dorsal habitus and genitalic structures, drawings and images of selected morphological characters, and distribution maps of all valid species are presented.

The Old World water scavenger beetle genus Sternolophus Solier is revised. Six new species are described: Sternolophus acutipenis sp. n., S. insulanus sp. n., S. jaechi sp. n., S. mandelai sp. n., S. prominolobus sp. n. and S. solitarius sp. n. Three taxa are reinstated as valid species: Sternolophus angustatus (Boheman), S. elongatus Schaufuss and S. mundus (Boheman). The subgenera within the genus are rejected and Neosternolophus Zaitzev syn. n. is synonymized with Sternolophus s. str. Lectotypes are designated for Hydrophilus angolensis Erichson, H. angustatus, H. rufipes Fabricius, Sternolophus brachyacanthus Régimbart, S. comoriensis Fairmaire, S. elongatus, S. frater Schaufuss, and S. rufipes var. foveoliceps Kolbe. On the basis of similar morphological characters, two species-groups are proposed for some of the species within the genus: The angolensis group including S. angolensis, S. inconspicuus (Nietner), S. mundus, and S. solitarius, and the solieri group including S. angustatus, S. elongatus, S. mandelai, S. rufipes Fabricius, and S. solieri Castelnau. Sternolophus unicolor (Castelnau) is considered a nomen dubium. Male genitalia and other diagnostic morphological characters are illustrated, and distribution maps are presented for all 17 species.

The genus Aspicera Dahlbom (Hymenoptera: Cynipoidea: Figitidae: Aspicerinae) is revised herein. Aspicera has a Holarctic distribution, being here cited for the first time from the following countries: Canada, Cyprus, Greece, India (northeastern corner, which is part of the Himalayan southeastern range and is considered as belonging to the Palaearctic), Japan, Jordan, Mexico, Montenegro, and Turkey. Morphological characters necessary to differentiate the species of Aspicera are described. The 27 previously described species of Aspicera were revised, always studying the type material when available (21 species); the type material of A. aegyptica Hedicke, 1928, A. chlapowskii Kieffer, 1901, A. coriacea Kieffer, 1901, A. lobata Hedicke, 1928, A. sibirica Kieffer, 1901, A. spinosa (Boyer de Fonscolombe, 1832) are lost or destroyed, these species were studied with the original descriptions. Of the 27 known species, 16 are considered as valid and are redescribed; A. effincta Belizin, 1952 is syn. nov. of A. suecica Dalla Torre & Kieffer, 1910, and A. brevispina Kieffer, 1901 and A. coriacia Kieffer, 1901 are syn. nov. of A. hartigi Dalla Torre, 1889. Aspicera nigra Ionescu, 1969, A. nigricornis Kirby, 1889 and A. rugosa (Hartig, 1843) do not belong to the Aspicerinae, but respectively to the genera Xyalophora and Neralsia (Figitinae), and Xyalaspis (Anacharitinae): Xyalophora nigra (Ionescu) n. comb., Neralsia nigricornis (Kirby) n. comb. and Xyalaspis rugosa Hartig status restored. Aspicera lobata Hedicke, 1928 is considered as ‘incertae sedis’. The examination of additional specimens suggests that there is a general lack of knowledge of the species diversity of this genus. Thirty two new species are described: A. adelae Ros-Farré n. sp., A. annae Ros-Farré & Pujade-Villar n. sp., A. belizini Ros-Farré & Pujade-Villar n. sp., A. blancae Ros-Farré n. sp., A. buffingtoni Ros-Farré & Pujade-Villar n. sp., A. caminali Ros-Farré n. sp., A. carinata Ros-Farré & Pujade-Villar n. sp., A. dianae Ros-Farré n. sp., A. kovalevi Ros-Farré & Pujade-Villar n. sp., A. elisendae Ros-Farré n. sp., A. forshzarai Pujade-Villar & Ros-Farré n. sp., A. gemmae Ros-Farré & Pujade-Villar n. sp., A. jantonii Ros-Farré n. sp., A. julii Ros-Farré & Pujade-Villar n. sp., A. kiefferi Ros-Farré & Pujade-Villar n. sp., A. magdae Ros-Farré & Pujade-Villar n. sp., A. marginata Ros-Farré & Pujade-Villar n. sp., A. martae Ros-Farré & Pujade-Villar n. sp., A. danielssoni Ros-Farré & Pujade-Villar n. sp., A. carlestolrai Ros-Farré & Pujade-Villar n. sp., A. mireiae Ros-Farré & Pujade-Villar n. sp., A. porif Ros-Farré n. sp., A. marginata Ros-Farré & Pujade-Villar n. sp., A. punctifrons Ros-Farré & Pujade-Villar n. sp., A. readae Ros-Farré & Pujade-Villar n. sp., A. robusta Ros-Farré & Pujade-Villar n. sp., A. santamariai Ros-Farré & Pujade-Villar n. sp., A. sergioi Ros-Farré n. sp., A. singularica Ros-Farré & Pujade-Villar n. sp., A. teresae Ros-Farré n. sp., A. tomasi Ros-Farré n. sp., A. zuparcoi Ros-Farré & Pujade-Villar n. sp.
