Two tribes of the Mecopodinae are represented in Australia. Both are confined to the tropics. The Australia Mecopodini comprises a single genus Austromecopoda, Rentz et al., with four species that occur in grasses adjacent to forests occurs on both sides of the continent. The Sexavini is reppresented by a single species of Segestidea, a genus with many species to the north of Australia, some of which are of economic important because of the damage they cause to Coconuts. This genus will be dealt with in a future paper. The taxonomy, biology and distribution are discussed in detail.

This is a continuation of the Monograph of Australian Tettigoniidae begun by the first author (see Rentz, 1985, 1993, 1995, Rentz et al. (2005). Approximately 70% of the Australian tettigoniid fauna remain to be described. It is now estimated to be in the area of 1500 species. This paper follows the protocols established in Rentz (1985).

Season-long sampling in streams and rivers produced 112 species of mayflies, which with other records totals 121 species for New Hampshire; 88 of these are new state records. Appearance of blackwing/mature larvae were used to develop statements on seasonality of species. Distinct differences were found between the faunas of southern and north-central New Hampshire, with an important factor being water temperatures through the season. A biogeographic analysis coupled with known habitat preferences reinforced the hypothesis that water temperature was a critical factor in determining species distributions in the state.

We conducted a phylogenetic analysis of the Afrotropical mayfly family Ephemerythidae using PAUP* and MacClade. The subgenus Tricomerella Demoulin proved to be applicable to a clade of species with apomorphically reduced hind wings that includes the type species of Ephemerythus Gillies and therefore is placed into strict synonymy with Ephemerythus [= Tricomerella, n. syn.]. Limnokijara, n. gen., is described for the second clade within Ephemerythidae and includes the species L. kiboensis (Gillies), n. comb., and L. picta (Gillies), n. comb. Limnokijara is differentiated from Ephemerythus by the adult males having stout spines distally on the inner margin of genital forceps segment 1. Larvae associated with Ephemerythus, s.s., have enlarged apical spines on the maxilla and abdominal gills 6 present. Larvae associated with Limnokijara have reduced apical spines on the maxilla and gills 6 absent.

Phylogeny of the cosmopolitan Ephemeroptera infraorder Pannota (Furcatergalia) is revised based on analysis of 46 characters from 34 Operational Taxonomic Units under the parsimony criterion of PAUP*, with Rhoenanthus Eaton (Scapphodonta: Potamanthidae) as an outgroup. Phylogenetic sequencing conventions were applied to the most parsimonious tree that was derived from this analysis. The resultant changes in classification include placing Philolimnias Hong, a monobasic genus from Eocene amber, into Philolimniidae, n. fam. Vietnamellidae is restricted to include only Vietnamella Tshernova, and Austremerella Riek is replaced in Austremerellidae, revalidation. Teloganella Ulmer is moved to Melanemerellidae (subfamily Teloganellinae, n. stat.). Coryphorus Peters is returned to Leptohyphidae (subfamily Coryphorinae, n. stat.).

Chilephotopsis Cambra and Quintero, a new genus of nocturnal Mutillidae, subfamily Sphaeropthalminae, is described and illustrated based on two new species from northern Chile, known from males only: Ch. aconcagua n. sp. and Ch. brothersi n. sp. The genus can be distinguished from other sphaeropthalmine genera by the deeply emarginate medial posterior margin of metasomal tergum seven and the highly modified paramere. A discussion of possible relationships with other nocturnal sphaeropthalmine genera from South America is presented.

A new species of genus Astemma is described from Argentina. A photograph of habitus and illustration of male genitalia are included.

Chaetochile Mitchell (Megachilidae) is herein confirmed as a subgenus of Megachile and represented by one species M. (Chaetochile) mitchelli Raw. The subgenus is characterized by a clypeus and supraclypeal area which is flat in the female, a second mandibular tooth which truncate and closer to the first than to the third tooth; T6 with an anterior depression and the distal margin with a conspicuous expansion and one spine on each side in the male. This contribution includes a redescription of M. Chaetochile and its single species.

The adult of the predaceous midge Stilobezzia fiebrigi Kieffer is redescribed and illustrated by using binocular compound microscope, and the pupa is redescribed by using binocular microscope and Scanning Electron Microscope. Immature stages were collected as pupae in mud in flooded soil in Corrientes province, Argentina. Adult and pupae are compared with their similar congener Stilobezzia coquilletti Kieffer.

Six hundred larvae of all instars of Aedes aegypti Linnaeus, 1762 (Diptera: Culicidae) were experimentally infected with larvae of Paragordius varius (Leidy, 1851) (Gordiida: Nematomorpha). All A. aegypti larvae were examined under a light microscope in order to assess the percentage of parasitized larvae, the number of P. varius larvae per A. aegypti larva and their location (thorax and/or abdomen). ANOVA was used for statistical testing of treatment effects. Data of the number of P. varius larvae per A. aegypti larva were log transformed and analyzed by two-factors ANOVA (instars: 1^st, 2^nd, 3^rd, 4^th; position: thorax and abdomen). Means were compared by Tukey test and the significance level was set at P< 0.05. The results obtained showed that A. aegypti larval mortality, at 2h 30min after infection, was higher in parasitized larvae (42.5 %) than in the control group (3 %). First and 2^nd instar larvae were the most susceptible to parasitism (52.15% and 46.67 % respectively). More than 90% of each instar A. aegypti larvae were parasitized and the percentage parasitism did not differ between instars. More parasitic larvae were found in 1^st and 2^nd instar A. aegypti larvae than in 3^rd and 4^th instars. Paragordius varius parasitize predominantly the abdomen. 9.1% 3^rd instar and 68.4% 4^th instar Aedes aegypti larvae induced an internal defense reaction (IDR). No infection was registered in the control group.

A detailed description and illustration of the larva of Macrothemis ultima González-Soriano is provided, based upon larvae reared until emergence. Its main features are: body dark brown, integument mostly bare, premental setae 7 3 or 8 4, ligula prominent, palpa setae 6, dorsal protuberances on abdomen well developed and high on 2–5, low, spine-like on 6–9, total length 15.8–16.5 mm. It appears more closely related to the larva of M. aurimaculata Donnelly than to others.

The species of the genus Phyllovates Kirby from west South America are revised. Six valid species are recognized, and P. gracilicollis n. sp. and P. brevicollis n. sp. are described. P. stolli (Saussure & Zehntner), previously treated as a synonym for P. tripunctata (Burmeister), is returned to species status. A key is provided.

A globally distributed cricket species, Gryllodes sigillatus (Walker), has recently been treated as a junior synonym of Gryllodes supplicans (Walker) from Sri Lanka. Examination of the male genitalia indicate that G. sigillatus is distinct from the Sri Lankan species. Two species were described from Sri Lanka — G. supplicans, and its junior synonym, G. greeni Chopard. The type of G. supplicans is lost. A syntype male of G. greeni is here designated as the neotype of G. supplicans.
