The diving beetles Liodessus altoperuensissp. nov. and Liodessus caxamarcasp. nov. (Dytiscidae, Hydroporinae, Bidessini) are described from the high altitudes of the Puna regions of north western Peru. They occur in shallow and exposed mossy peatland puddles. We delineate the two species using structures such as male genitalia, beetle size, shape and colour pattern. Mitochondrial Cox1 data were also generated, and revealed clusters congruent with morphological evidence. Altogether fourteen Liodessus species are now known from the Andean region.

Minute Bidessini diving beetles of the genus Neoclypeodytes Young, 1967 from Panama are reviewed. Two new species, Neoclypeodytes balkei sp. nov. and N. fortunensis sp. nov. are described from Campana, Panama Province in central Panama, and La Fortuna, Chiriqui province in western Panama, respectively. Both species differ from all congeners by the colour pattern of the elytra and the shape of the male genitalia. Additionally, we provide a short diagnosis, illustrations and a new record for N. curtulus (Sharp, 1882). Furthermore, we report on the presence of scale-like setae at the apex of median lobe of the aedeagus of N. curtulus and N. fortunensis sp. nov., a character not previously observed in Neoclypeodytes species. With the addition of these two new species, there are now three species of Neoclypeodytes known from Panama and south of Guatemala.

Two new species of hippolytid shrimp are described from the continental margin of Western Australia, Lebbeus clarehannah sp. nov. from one female specimen collected off Bald Island, WA, at depths of 408–431 m and Lebbeus cristagalli sp. nov. from ten specimens collected off north-western Australia at depths of 397–458 m. Both species belong to the group of Lebbeus species possessing epipods on only the first two pairs of pereopods. Within this group, they are similar to L. yaldwyni Kensley, Tranter & Griffin, 1987 from NSW, Australia, and L. compressus Holthuis, 1947 from Japan in possessing a high crest on the carapace. These crested species of Lebbeus are reviewed. They can be distinguished from one another by the shape of the carapace crest, the number of spines on maxilliped 3 and by colour pattern. A key to all crested species and colour photos of the Australian species are provided.

Morphology and mitochondrial DNA sequence data are used to reassess the taxonomy of Australian diving beetles previously assigned to the genera Uvarus Guignot, 1939 and Gibbidessus Watts, 1978. Gibbidessus was described as a monotypic genus for Gibbidessus chipi Watts, 1978. The genus is significantly extended here. Based on molecular systematic evidence, Uvarus pictipes (Lea, 1899) is transferred to Gibbidessus. Gibbidessus chipi and Gibbidessus pictipescomb. nov. are redescribed, and six new species are described: Gibbiddessus atomussp. nov. (SW Australia, Northcliffe area) [the smallest epigean diving beetle in Australia], G. davidisp. nov. (SW Australia), G. drikdrikensissp. nov. (Victoria), G. kangarooensissp. nov. (SA Kangaroo Island), G. pederzaniisp. nov. (SW Australia, Nannup area), and G. rottnestensissp. nov. (SW Australia). Species are delineated using characters such as male genital structure and beetle size, shape and colour pattern. Mitochondrial Cox1 data for 27 individuals, representing five species, were generated, and revealed clusters congruent with the morphological evidence. Gibbidessus occur in southern Australia, with the centre of diversification in the isolated peat- and wetlands of SW Australia. All species occur in very shallow water of seasonal, exposed or half-shaded wetlands and flooded meadows.

Two new species of reticulated beetles (Cupedidae) are described: Tenomerga angulinota sp. nov. from Laos and T. helii sp. nov. from Sichuan, China. Important morphological characters of both new species are illustrated. T. angulinota sp. nov. can be easily recognized from all other Palaearctic-Oriental species by bifid anterior angles of pronotum; T. helii sp. nov. is in habitus very similar to widespread T. anguliscutis (Kolbe, 1886) and can be distinguished based on shape of pronotum, colour pattern of elytra and predominantly male genitalia. In addition, T. anguliscutis is for the first time recorded from Hainan and Jiangxi Provinces of China.

Penthicodes celebica n. sp., is described from Sulawesi, P. warleti n. sp. from India (Assam) and P. caja malayana n. ssp. from peninsular Malaysia. They are compared with the allied species of the subgenus Ereosoma Kirkaldy, 1906, as treated by Nagai & Porion (1996): P. astraea (Stål, 1864), P. atomaria (Weber, 1801) P. bimaculata (Schmidt, 1905), P. caja (Walker, 1851), P. pulchella (Guérin-Méneville, 1838), P. quadrimaculata Lallemand, 1963, P. rugulosa (Stål, 1870) and P. variegata (Guérin-Méneville, 1829). Penthicodes quadrimaculata is removed from synonymy with P. bimaculata. Male genitalia of all treated species are illustrated and described. New geographical records, distribution maps, behaviour data and photographs of habitus are given. An illustrated identification key to all 12 species of the genus, including P. farinosa and P. nicobarica, is proposed. Penthicodes basigera (Walker, 1870) is transferred to the genus Scamandra Stål, 1863 and the new combination Scamandra basigera (Walker, 1870) n. comb. is proposed. The subgenus Ereosoma is regarded as heterogenous and the species are separated in 2 new species-groups on the base of the male genitalia and colour pattern: group astraea+ (astraea, bimaculata, caja, celebica, quadrimaculata, rugulosa and variegata) and group atomaria+ (atomaria, pulchella, warleti).

Two new species of Pentacalia are described herein on the basis of morphological evidence. These new findings are the result of field work and recent herbarium studies carried out at USM. Both species are very distinctive and any confusion with the other known taxa of the genus is unlikely. Both species are hitherto only known from the type locality, one collected in Junín Department (central Peru) and the other in Amazonas Department (northern Peru). They grow in Andean humid montane forests. Pictures of the respective holotypes and a distribution map are provided. Moreover, the name P. marinii is synonymized under P. herzogii, as well as P. megaphlebia to P. oronocensis.

A New Species

Abstract Culex longitubus Somboon, Namgay & Harbach is described as a new species of the Mimeticus Subgroup of the subgenus Culex. The larva is most similar to the larva of Cx. tianpingensis Chen from China, but is distinguished by the length of the siphon and the anal papillae, the form of the comb scales and pecten spines, and the development of setae 7-P, 13-T, 1-X, and 4-X. The adults have wing markings and male genitalia similar to those of species of the Mimeticus Complex. Phylogenetic analysis of COI sequences revealed that the new species is closely related to Cx. murrelli Lien of the Mimulus Complex. The immature stages of the new species were found in stagnant pools and marshes at high altitudes in several districts of Bhutan.

Two New Species

The genus Agrotera Schrank, 1802 is revised for Australia and the generic definition is refined based on the male genitalia. The genera Leucinodella Strand, 1918 stat. rev. with L. leucostola (Hampson, 1896) comb. nov., Nistra Walker, 1859 stat. rev. with N. coelatalis Walker, 1859 comb. rev., Sagariphora Meyrick, 1894 stat. rev. with S. magnificalis (Hampson, 1893) comb. nov., and Tetracona Meyrick, 1884 stat. rev. with T. amathealis (Walker, 1859) comb. rev. and T. pictalis Warren, 1896 comb. rev. are removed from synonymy with Agrotera, as they lack the synapomorphies of Agrotera. Two new species, Agrotera genuflexa sp. nov. from Northern Territory, Queensland and New South Wales, and A. longitabulata sp. nov. from Queensland, are described. The taxonomic status of the Australian species of Agrotera is discussed, and a key to all species, based on males, is provided. The adults and genitalia of the new species and some related species are figured.

Two new species of South African Syllidae of the genusSyllisLamarck, 1818 are described.Syllis unzimasp. nov. is characterized by having unidentate compound chaetae with long spines on margin, a characteristic colour pattern and its reproduction by vivipary. Vivipary is not common among the polychaetes, but most representatives occur in the family Syllidae Grube, 1850 (in five otherSyllisspecies, two species ofDentatisyllisPerkins, 1981 and two species ofParexogoneMesnil & Caullery, 1818).Syllis unzimasp. nov. differs from the other viviparous species in having large broods (>44 juveniles) which develop synchronously. Development of the juveniles is similar to that of free-spawningSyllisspecies, but the appearance of the first pair of eyespots and the differentiation of the pharynx and proventricle occur later inS. unzima.Syllis amicarmillarissp. nov., is characterized by having an elongated body with relatively short, fusiform dorsal cirri and the presence of one or two pseudosimple chaeta on midbody parapodia by loss of blade and enlargement of shaft.Syllis unzimasp. nov. was found in high densities on culturedHolothuria scabraJaeger, 1833 with single specimens found on a culturedCrassostrea gigasThunberg, 1793 and on coralline algae, respectively, whileS. amicarmillariswas found mainly in sediment outside an abalone farm and less frequently on culturedHaliotis midaeLinnaeus, 1758. We discuss the possible benefits of the association withH. scabratoS. unzimasp. nov.
