Riffle bugs in the genus Rhagovelia have diversified extensively on the island of Madagascar. The current paper defines and segregates a distinct set of species within this endemic assemblage as the tesari species-group, containing the previously described species R. tesari Hoberlandt, R. adrienneaebrasili Poisson, R. hovana Hoberlandt, R. abalienata Hoberlandt, R. tsaratananae Poisson, and R. mohelii Poisson (originally described as a subspecies of R. tesari but here raised to full species status), as well as the following 13 new species described herein: R. aquacola n. sp., R. ambra n. sp., and R. sahabe n. sp. from northern Madagascar; R. mandraka n. sp., R. faratsihoi n. sp., and R. wenzeli n. sp. from central Madagascar; R. enckelli n. sp., R. takona n. sp., R. manga n. sp., R. brincki n. sp., and R. sandoka n. sp. from eastern Madagascar; R. andringitrae n. sp. from south-central Madagascar; and R. mondena n. sp. from southeastern Madagascar. Rhagovelia tesari flavomarginata Hoberlandt 1951 is synonymized under R. adrienneaebrasili Poisson 1945. Figures of key morphological characters, including male parameres are provided for all species, accompanied by distribution maps.

A new species of Labuanium Serène & Soh, 1970, L. vitatum is described from northeastern Indian Ocean. It belongs to the L. rotundatum species-group, but is most closely related to L. scandens Ng & Liu, 2003, and L. papuomalesiacum (Nobili, 1899), the latter being here formally removed from synonymy with L. rotundatum (Hess, 1865) and raised to full species status. The new species differs from congeners by numerous characters including the structure of the male first pleopod, carapace and third maxillipeds, and by differences in proportions of the male abdominal somites.

Species of the genus Hebius Thompson, 1913 with 17 or 19 dorsal scale rows at midbody and an overall dark venter are reviewed, including the two species previously known as Parahelicops annamensis Bourret, 1934 and Pararhabdophis chapaensis Bourret, 1934. Specimens with 17 scale rows are morphologically similar to Hebius venningi (Wall, 1910), which is here redefined based on external morphological characters such as scalation, and dorsal and ventral patterns. Consequently, Natrix nigriventer Wall, 1925 is resurrected from its synonymy with Hebius venningi, whereas Natrix taronensis Smith, 1940, previously considered a subspecies of H. venningi or a full species by some authors but without justification, is here confirmed to full species status. Another group of species, mostly similar in coloration and pattern to the H. venningi group but with 19 dorsal scale rows, includes H. modestus (Günther, 1875), H. deschauenseei (Taylor, 1934) and a new species which is described herein based on specimens from northern Vietnam, southern China and north-eastern Thailand due to distinct morphological differences. We also provide updated taxonomic accounts for the species of this group, including an identification key and distribution maps.

The Indo-Australian crowned weevil genus Asytesta Pascoe, 1865 is revised. Forty-one species are recognized, including18 that are new: A. alexandriae, A. alexriedeli, A. allisoni, A. biakana, A. cheesmanae, A. concolora, A. emarginata, A.fayae, A. frontalis, A. gressitti, A. julieae, A. marginalis, A. morobeana, A. sedlaceki, A. thompsoni, A. tuberculata, A.vivienae, and A. woodlarkiana, new species. One subspecies, A. lugubris bidentata Voss is elevated to species status, A.bidentata Voss, new status. Four species are newly synonymized: A. circulifera Lea, 1928 = A. rata Heller, 1910, A.definita Faust, 1898 = A. humeralis Pascoe, 1865, A. granulifera Lea, 1928 = A. aucta Faust, 1898, and A. setipes Lea,1928 = A. lugubris Heller, 1895 new synonyms. Six new species groups are proposed. Lectotypes are designated for 18species. Two species are transferred from Asytesta to other genera: A. maura Pascoe to Microporopterus Lea and A.ypsilon Heller to Meroleptus Faust, new combinations. A checklist and key for all crowned weevil genera, key to speciesgroups and species of Asytesta, adult habitus illustrations, distribution maps, and line drawings of diagnostic charactersare provided.A phylogeny for the genus based on 82 adult morphological characters (187 states) for 41 ingroup taxa is alsopresented. All genera and species of the crowned weevil group as redefined here (including Cyamomistus Heller,Eudyasmus Pascoe, Glochinorhinus Waterhouse, Nothotragopus Zimmerman, Panopides Pascoe, and Zygara Pascoe),were included in the analysis to test the monophyly of Asytesta. Monophyly of Asytesta was supported only with thesynonymy of the monotypic genus Zygara. Accordingly, Zygara is a new junior synonym of Asytesta and Zygara doriae (Kirsch) is returned to its original combination with Asytesta; A. doriae Kirsch resurrected status.

Seven new species from India are described in the Mesovelia horvathi species complex and assigned to two putatively monophyletic species groups. Mesovelia brevia sp. nov. and M. dilatata sp. nov., both occurring in Tamil Nadu and Meghalaya, and M. occulta sp. nov., known from only Tamil Nadu, are described and placed in the Mesovelia horvathi species group. Mesovelia andamana sp. nov. from the Andaman Islands, M. bispinosa sp. nov. and M. isiasi sp. nov. from Meghalaya, and M. tenuia sp. nov. from Tamil Nadu, are described and placed in the M. andamana species group. Photographs of morphological characters, distribution maps, and a key to males are provided for all of the species treated.

The Australian Anthracini are revised. In all, 28 new species are described, bringing the total fauna to 34 species. The previously described species of Anthrax Scopoli – A. maculatus Macquart, A. incomptus Walker, A. confluensisRoberts, A. lepidiotus Roberts and A. proconcisus Hardy – are diagnosed and the following eight new species of Anthrax are described: A. argentia, A. asciculus, A. clinatus, A. crenatus, A. dolabratus, A. funestus, A. opacus and A. torulus. This taxonomic study reveals a group of at least 20 cryptic species previously included in collections under the name Anthrax angularis Thomson. A new genus, Thraxan, is erected to contain this cryptic group of species and the following 20 new species are described: T. acutus, T. abditus, T. caligneus, T. cinctus, T. cornuatus, T. depressus, T. echinatus, T. ebenus, T. emicatus, T. hamulus, T. luteus, T. misatulus, T. nodus, T. norrisi, T. obstipus, T. patielus, T. planus, T. prolatus, T. simulatusand T. spiculus. Many of these cryptic species have been collected sympatrically, hill topping together in eastern Australia. A key is provided to the species of Anthrax and Thraxan, genitalia drawings are presented for most species and distribution maps of all species are presented. A cladistic analysis of the species of Anthrax and Thraxan is also presented. A total of 26 of the species is compared for 125 synapomorphies in 39 adult morphological characters. Three species-groups were found: Thraxan, and two species-groups within Anthrax, the A. proconcisus species-group and the A. maculatusspecies-group. Previous authors divided Anthrax into species-groups on the basis of wing patterns, but found that these species-groups were not confirmed when other characters were taken into consideration. We studied the congruence of seven different character sets within the clade comprising Anthrax and Thraxan – antennae, venation, wing patterns, vestiture, genitalia, male genitalia and female genitalia – using several incongruence indices. Significance of incongruence was measured using a randomisation procedure. Results of these studies indicate that the wing-pattern character set is significantly incongruent with the other morphological data. These quantitative cladistic results explain the difficulty previous authors experienced in finding suites of characters to support species-groups in Anthrax on the basis of wing patterns. A relationship is found between the level of incongruence and the distance over which mate-recognition signals operate.

A survey of the whirligig beetles of the genus Patrus Aubé, 1838 occurring in Thailand belonging to the newly designated Patrus landaisi species group is presented. Three new species are described and illustrated: P. garuda sp. nov., P. nanensis sp. nov. and P. phetchabunensis sp. nov.; with P. apicalis (Régimbart, 1891), P. landaisi (Régimbart, 1892), and P. subapicalis (Ochs, 1930) stat. nov. being recorded for the first time in Thailand. Morphological and molecular analyses, together in an integrative approach, support the elevation of P. subapicalis to species status, instead of being a subspecies of P. apicalis. A diagnosis, illustrations of habitus and diagnostic characters, distribution maps, habitat images and a key to species are provided for all known members of the P. landaisi species group that occur in Thailand. A checklist of species in the group is also given.

The particularly speciose cheilostomate genus Microporella includes taxa whose maternal zooids and associated ovicells present a personate structure, i.e. a particularly developed peristome. Six species of Microporella with personate ovicells are analysed from material sampled in the Indian Ocean, Red Sea and southeast Mediterranean. Consideration of highly diagnostic tiny morphological characters displayed by the primary orifice and the avicularium has made it possible to distinguish three new species, M. browni n. sp., M. maldiviensis n. sp. and M. collaroides n. sp., and to better characterise the other species. Among the latter, two species named by Audouin (1826) from Savigny’s drawings (1817), M. coronata and M. genisii, are redescribed and neotypes are selected. Additionally, a new species of the M. coronata species group, Microporella hastingsae n. sp., is proposed following examination of a museum specimen recorded as M. ciliata var. coronata (Hastings 1927). The species dealt with in this study revealed remarkably different patterns of geographic distribution, possibly showing different potential for natural and/or anthropogenic dispersal. The bryozoan assemblages sampled along the coast of Lebanon include four of the six studied species, at least three of them presumably non-indigenous including M. harmeri Hayward, which displays a remarkably wide distribution from the Indian Ocean to the West Pacific and the East Atlantic (Canary Islands).

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.
