A rheophylous cladoceran, Rheoalona mekongensis sp. nov., gen. nov. (Anomopoda: Chydoridae: Aloninae) is described from the Mekong River, South-East Asia. Rheoalona gen. nov. belongs to the Coronatella-branch of Aloninae, it differs from Karualona Dumont & Silva-Briano, 2000 in absence of seta 1 of IDL of thoracic limb I and by particularly strong lateral setae of postabdomen; from Anthalona Van Damme, Sinev & Dumont, 2011 in a wide connection between major head pores, lack of cosmaria, and two-flaming torch setae of limb IV; and from Coronatella Dybowski & Grochowski, 1894 in two major head pores, very small elementary denticles of postabdomen, and a very small basal spine of postabdominal claw. R. mekongensis sp. nov. is specially adapted for dwelling in the upper layer of fine sediments of turbid rivers. Our finding stress the importance of sampling in riverine habitats for the full inventories of the cladoceran fauna.

Abstract Gilen gen. nov. (type species G. orientalis sp. nov.) from South East Asia is described and illustrated. The new taxon has a produced mid-longitudinal facial projection, which differentiates it from all other known genera of Ichneumonidae. It belongs to the tribe Perilissini in the subfamily Ctenopelmatinae (Hymenoptera, Ichneumonidae) and is recorded from Laos, Northern Thailand and Vietnam.

We describe a new genus, Manitischeria Diškus & Stonis, gen. nov., and five new species: Manitischeria selindica Stonis & Diškus, sp. nov., M. namibiensis Stonis & Diškus, sp. nov. from Africa, and M. brachiata Diškus & Stonis, sp. nov., M. symbolica Diškus & Stonis, sp. nov., and M. baryshnikovae Diškus & Stonis, sp. nov. from South East Asia. We discuss the diagnostics of Manitischeria gen. nov. composed of these new species and others transferred from Tischeria Zeller. Species are mostly trophically associated with Malvaceae, but also Rhamnaceae and Betulaceae. We list 18 currently known species of Manitischeria gen. nov., including M. ptarmica (Meyrick), the type species, and provide 13 new combinations and the first documentation of genitalia of some, previously little-known species. New species are illustrated with photographs or drawings of the adults, genitalia, and the leaf mines when available. We briefly discuss the use of herbarium specimens to discover lepidopteran leaf mines, host plant, and distribution data.

A new gonibregmatid centipede,Vinaphilusunicusgen. n.,sp. n., is described based on two females from a single location in northern Vietnam. The new genus and species are distinguished mainly by the arrangement of the ventral pore-fields, which is unique among all Chilopoda. A critically revised synopsis of the Gonibregmatidae is also given. In particular, three species are provisionally recognized inHimatosomaPocock, 1891:H.bidivisumSilvestri, 1919,H.porosumPocock, 1891 (=H.typicumtridivisumSilvestri, 1919,syn. n.), andH.typicumPocock, 1891. The generaDschangelophilusVerhoeff, 1937 andTweediphilusVerhoeff, 1937, with their speciesD.coloratusVerhoeff, 1937 andT.malaccanusVerhoeff, 1937, are moved to the Gonibregmatidae, whereasGeoporophilusaporusAttems, 1930 is moved to the Oryidae asOrphnaeusaporus(Attems, 1930),comb. n.

By taking Flavalona gen. nov. out of Alona s.l. (Cladocera: Anomopoda: Chydoridae), the last major clade has now been removed from this polyphyletic assemblage. Flavalona gen. nov. is a monophylum defined by having three, rarely two connected head pores and slit-shaped, rarely rounded lateral head pores. Postabdomen rather long, distally narrowed, with robust marginal denticles and weakly developed lateral fascicles of setules. End-claw weakly curved and with short basal spine. Male postabdomen with gonopores opening at the end of a penis-like outgrowth. Trunk limbs: exopodite of P2 with seta; inner portion of P4 with flaming-torch shaped setae; P5 with filter plate of three setae; P6 a large simple lobe. The relationship of the new genus with other Aloninae remains to be determined. A key to the 11 species of the genus is provided and a discussion of their geographic distribution and habitat type is given.

Genus Level

Mekongomantis quinquespinosa gen. et sp. nov., a new Mantidae genus and species is described based on specimens from two localities—Lam Vien plateau in Vietnam and the environments of Umphang, Thailand. The new genus has five posteroventral spines on the forefemur, a feature previously unknown in any Mantidae (sensu stricto) genus. The rest of external morphology is similar to Tenodera Burmeister, 1838 and Mantis Linnaeus, 1758, while the characters of the male genitalia place the species more closely to Hierodula Burmeister, 1838 and Camelomantis Giglio-Tos, 1917. The discovery of such a large (>70 mm) genus level taxon exemplifies the poorly studied diversity of Mantodea in the rapidly deteriorating Greater Mekong area. To ease identification, we also provide a key to the Mantidae of South-East Asia.

Significance The Mekong flows through China and the five mainland South-east Asian states -- Myanmar, Thailand, Cambodia, Laos and Vietnam. Earlier this month, China belatedly informed the downstream Mekong countries of reduced water flow because of power-line maintenance at one of its dams on the river. Impacts US partners India and Japan will look to strengthen economic ties with the South-east Asian Mekong states. Climate change and low rainfall will exacerbate droughts in mainland South-east Asia. The China-led Lancang-Mekong Cooperation initiative will dominate management of the Mekong, overshadowing the Mekong River Commission.

Two New Species

As part of an ongoing effort to revise the taxonomy of air-breathing, marine, onchidiid slugs, a new genus, Laspionchis Dayrat & Goulding, gen. nov., is described from the mangroves of South-East Asia. It includes two new species, Laspionchis boucheti Dayrat & Goulding, sp. nov., and Laspionchis bourkei Dayrat & Goulding, sp. nov., both distributed from the Malacca Strait to the Philippines and Australia. This study is based on extensive field work in South-East Asia, comparative anatomy, and both mitochondrial (COI and 16S) and nuclear (ITS2 and 28S) DNA sequences. The two new species are found in the same habitat (mud surface in mangrove forests) and are externally cryptic but are distinct anatomically. Both species are also strongly supported by DNA sequences. Three cryptic, least-inclusive, reciprocally-monophyletic units within Laspionchis bourkei are regarded as subspecies: L. bourkei bourkei Dayrat & Goulding, ssp. nov., L. bourkei lateriensis Dayrat & Goulding, ssp. nov., and L. bourkei matangensis Dayrat & Goulding, ssp. nov. The present contribution shows again that species delineation is greatly enhanced by considering comparative anatomy and nuclear DNA sequences in addition to mitochondrial DNA sequences, and that thorough taxonomic revisions are the best and most efficient path to accurate biodiversity knowledge.

Molecular Phylogenetic Data

A new genus, Anthelepis R.L.Barrett, K.L.Wilson & J.J.Bruhl, is described for four Cyperaceae species from mainly tropical areas of South-East Asia, New Caledonia and Australia. The relationships of the three previously described species have been much-debated. In recent decades, they have most commonly been placed in either Schoenus L. or Tricostularia Nees ex Lehm., but molecular phylogenetic data have demonstrated that they are not closely related to either genus and a new generic name is required. The following three new combinations are made: Anthelepis guillauminii (Kük.) R.L.Barrett, K.L.Wilson & J.J.Bruhl (based on Schoenus guillauminii Kük.), A. paludosa (R.Br.) R.L.Barrett, K.L.Wilson & J.J.Bruhl (based on Chaetospora paludosa R.Br.) and A. undulata (Thwaites) R.L.Barrett, K.L.Wilson & J.J.Bruhl (based on Cladium undulatum Thwaites). One new species, Anthelepis clarksonii R.L.Barrett, K.L.Wilson & J.J.Bruhl, is described from northern Queensland, Australia, as distinct from A. undulata. Full descriptions, illustrations and a key to species are provided. All species are confirmed as having C3 anatomy.
