Based on specimens in various museum collections one new subgenus and six new species of Elimaeini are described: Poaefoliana subgen. n. (type species Locusta poaefolia De Haan, 1842) of Elimaea Stål, 1874; Elimaea (Poaefoliana) albimaculata sp. n., E. (P.) jitra sp. n., E. (P.) kutu sp. n., Elimaea (Schizelimaea) singgalang sp. n., Orthelimaea kanburi sp. n., O. volsella sp. n. Three classical species were also combined with the new subgenus: Elimaea (Poaefoliana) poaefolia (De Haan, 1842) comb. n., E. (P.) rosea Brunner v. Wattenwyl, 1878 comb. n., E. (P.) jacobsoni Karny, 1926 comb. n. A lectotype for E. rosea is fixed as the type series is not homogenous. © 2011 - Magnolia Press.

Identification of various unworked museum specimens and newly received material from Sabah, Peninsular Malaysia, Singapore, North Thailand, and North East India resulted in the discovery of new taxa of Mirolliini. Two genera and twelve species are described as new: Amirollia gen. n. (type species A. furcata sp. n.), Hemimirollia gen. n. (type species Mirollia gracilis Karny, 1925); Amirollia furcata sp. n.; Deflorita marginata sp. n., D. protecta sp. n., Hueikaeana andrejisp. n., H. quadrimaculata sp. n., Mirollia forcipata sp. n., M. malaya sp. n., M. paralata sp. n., M. rumidi sp. n., M. secundasp. n., M. spinulosa sp. n., and M. tawai sp. n. Four new combinations are proposed: Mirollia gracilis Karny, 1925 and M. luteipennis Karny, 1925 are combined with Hemimirollia; Mirollia ulla Gorochov, 2008 is combined with Amirollia; Hueikaeana decora Gorochov, 2008 is combined with Deflorita and the male described for the first time. The females of Deflorita bella Gorochov, 2008 and Mirollia longipinna Ingrisch & Shishodia, 1998 are described for the first time. Stridulation of M. secunda sp. n. is reported. The study also revealed formerly unreported modifications of the anterior abdominal tergites in males of all species under study, which are interpreted as abdominal glands. © 2011 Magnolia Press.

Pituitary adenylate cyclase-activating polypeptide (PACAP) administered to tilapia melanophores ex-vivo causes significant pigment aggregation and this is a newly identified function for this peptide in fish. The G-protein coupled receptors (GPCRs), adcyap1r1a (encoding Pac1a) and vipr2a (encoding Vpac2a), are the only receptors in melanophores with appreciable levels of expression and are significantly (p < 0.05) down-regulated in the absence of light. Vpac2a is activated exclusively by peptide histidine isoleucine (PHI), which suggests that Pac1a mediates the melanin aggregating effect of PACAP on melanophores. Paradoxically activation of Pac1a with PACAP caused a rise in cAMP, which in fish melanophores is associated with melanin dispersion. We hypothesise that the duplicate adcyap1ra and vipr2a genes in teleosts have acquired a specific role in skin and that the melanin aggregating effect of PACAP results from the interaction of Pac1a with Ramp that attenuates cAMP-dependent PKA activity and favours the Ca2+/Calmodulin dependent pathway. © 2015 Elsevier Ireland Ltd.

Allatostatin type A receptors (AST-ARs) are a group of G-protein coupled receptors activated by members of the FGL-amide (AST-A) peptide family that inhibit food intake and development in arthropods. Despite their physiological importance the evolution of the AST-A system is poorly described and relatively few receptors have been isolated and functionally characterised in insects. The present study provides a comprehensive analysis of the origin and comparative evolution of the AST-A system. To determine how evolution and feeding modified the function of AST-AR the duplicate receptors in Anopheles mosquitoes, were characterised. Phylogeny and gene synteny suggested that invertebrate AST-A receptors and peptide genes shared a common evolutionary origin with KISS/GAL receptors and ligands. AST-ARs and KISSR emerged from a common gene ancestor after the divergence of GALRs in the bilaterian genome. In arthropods, the AST-A system evolved through lineage-specific events and the maintenance of two receptors in the flies and mosquitoes (Diptera) was the result of a gene duplication event. Speciation of Anophelesmosquitoes affected receptor gene organisation and characterisation of AST-AR duplicates (GPRALS1 and 2) revealed that in common with other insects, the mosquito receptors were activated by insect AST-A peptides and the iCa iCa2+-signalling pathway was stimulated. GPRALS1 and 2 were expressed mainly in mosquito midgut and ovaries and transcript abundance of both receptors was modified by feeding. A blood meal strongly up-regulated expression of both GPRALS in the midgut (p < 0.05) compared to glucose fed females. Based on the results we hypothesise that the AST-A system in insects shared a common origin with the vertebrate KISS system and may also share a common function as an integrator of metabolism and reproduction. Highlights: AST-A and KISS/GAL receptors and ligands shared common ancestry prior to the protostome-deuterostome divergence. Phylogeny and gene synteny revealed that AST-AR and KISSR emerged after GALR gene divergence. AST-AR genes were present in the hemichordates but were lost from the chordates. In protostomes, AST-ARs persisted and evolved through lineage-specific events and duplicated in the arthropod radiation. Diptera acquired and maintained functionally divergent duplicate AST-AR genes. © 2015 Felix et al.

Axylus group is used to include the five genera Axylus Stål, 1877, Anthracites Redtenbacher, 1891 sensu stricto, Eucoptaspis Willemse, 1966, Eulobaspis gen. nov., and Heminicsara Karny, 1912. It is mainly based on a combination of the characters shape of pronotum, spiniform meso- and metasternal lobes, and similar basic ground plans of the male cerci, titillators and female subgenital plates. The five genera together with two superficially similar genera Euanthracites gen. nov. and Sulasara gen. nov. are fully revised.
