We describe a new species of Corynura Spinola, a socially polymorphic genus within the bee tribe Augochlorini (Halictidae). We present a detailed description of both sexes of Corynura (Corynura) moscosensis n. sp. González-Vaquero, images of diagnostic morphological structures and antennal sensilla, floral associations, distributional data and notes on its nesting biology. Corynura moscosensis n. sp. is similar in appearance to C. (C.) chloromelas (Alfken), but it can be distinguished by the sculpturing of the mesoscutum and the hair types on the propodeum in the female, and by the genitalia and extent of the area exclusively covered by sensilla placoidea on the antennal flagellum of the male. A lectotype is designated for C. chloromelas. A Chilean Patagonian population of C. moscosensis n. sp. was observed to dig spatially clumped nests in an earth bank with a moderately hard and humid soil. The presence of multiple females within single nest tunnels is unusual and may preliminary suggest nest-sharing, but more data are necessary to define the social organization of this species. The species appears to be polylectic. Bee nests were attacked by satellite flies and possibly velvet ants.

A new species, Hypogastrura sheyangensis, from East China is described. It belongs to H. manubrialis group of species within the genus and is easily separated from the other members of the group by a combination of characters, foot structure, furca, antennal sensilla, thoracic and abdominal chaetotaxy. A comparison is made between the new species, other species of Hypogastrura known from China and three other similar species in the genus.

The Neotropical genus Benthana Budde-Lund, 1908 includes 22 species, three of them allocated to the subgenus Benthanoscia Lemos de Castro, 1958. A new species is described from the state of Paraná, Brazil. This new species is distinguished from its congeners by having 8+2 aesthetascs on the antennula, the first article of the antennal flagellum unpigmented, the proximal inner tooth of the inner pectinate set of the maxillula with 7 denticles, and the pleopod 1 exopod with a dentiform protrusion with a concave appearance.

Arpactophilus mimi, Naumann, sp. nov., is described from Kakadu National Park, N.T. and its biology is outlined. A. mimi nests in abandoned cells of mud-dauber wasps in sandstone overhangs. Its nests are lined heavily with silk and contain 1-15 cells and 1-10 adult wasps (1-7 females, 0-3 males). On average nests contain 5.2 cells and 2.75 adult females. Prey (immature Psyllidae and Tingidae) are supplied progressively. Nests are parasitised by a species of megalyrid wasp, but incidence of parasitism is low. Nest defense is both physical (entrance guard always present) and chemical (citrus odour from heads of both sexes). Females from a single nest could be ranked on the basis of relative ovarian development, suggesting that more than one female oviposits. Females apparently cooperate in brood care and offspring in a nest develop asynchronously. The biology of A. mimi is compared to that of Microstigmus comes Krombein, the most socially advanced sphecid known, and selective pressures that may have acted to promote female cooperation in the two genera are discussed. For A. mimi the lack of available nest sites could be an important factor restricting the ability of offspring to disperse and establish nests.

A new species of the rare ant genus Metapone, Metapone murphyisp. nov., is described based on museum material consisting of a single nest series (workers, queens, and males) collected from a decayed coconut palm stump on Pulau Sakra, previously an offshore island south of mainland Singapore. Workers can be distinguished from other named congeners mainly by the following characters: 1) subpetiolar lamella subrectangular; 2) short median longitudinal ventral subpetiolar edge and roundly obtuse posteroventral subpetiolar angle; 3) outer margin of posterior subpetiolar face in posteroventral view forming a continuous, U-shaped, translucent, laminate carina; and 4) petiole subtrapezoidal in dorsal view with extended blunt tooth-like posterolateral corners. Detailed description and illustrations of male genitalia of the genus are given for the first time. The key to Asian species of Metapone is updated to include the new species.

Ten Hypogastrura species have been found from India, two of which are described: H. unguiculata (Mitra, 1966) and H. satkosiaensis nov. sp. Two Indian species have been removed from Hypogastrura and have been included in the genus Ceratophysella based on their original descriptions: C. baltica (Tyagi & Baijal, 1982) comb. nov. and C. katraensis (Tyagi & Baijal, 1982) comb. nov. H. satkosiaensis sp. nov. belongs to H. manubrialis group of species within the genus and is easily separated from the other members of the group by a combination of characters, a greater number of antennal sensilla, dorsal chaetotaxy, specially presence of m1 chaeta on abdominal tergite V, and mucro shape. A key for all of the known Indian species of Hypogastrura is provided.

A trap-nesting program in northern Spain undertaken in cooperation with Dr. Enrique Asensio (Instituto Nacional de Investigaciones Agrarias, Valladolid) over the past few years has resulted in numerous nests of megachilids. One of these represents a new species of Protosmia Ducke. It is described here in order to make the name available for the description of its nesting biology, and is named in honor of Dr. Asensio, in recognition of his considerable help in this trap-nesting study.In the following description, abdominal segments are numbered based on the metasoma; expressions in parentheses in the description of the male represent departures among male paratypes from characteristics described for the holotype.

Abstract This paper summarizes the breeding biology, social organization, and mating system of the Striated Grasswren (Amytornis striatus), a member of one of the least-known genera of Australian passerines, the grasswrens. I studied 18 color-banded groups and 14 nests in South Australia for one breeding season in 1996. Mean territory size was 3.0 ha, and territories consisted of sandy dunes dominated by spinifex (Triodea irritans). This apparent dependency on mature spinifex, coupled with poor dispersal ability, suggests that the Striated Grasswren is particularly susceptible to habitat destruction. Most groups consisted of socially monogamous pairs, mean group size was 2.1 adults, and the adult sex ratio was 0.95 (males:females). The average clutch size was 2.2 ± 0.4 eggs and an average of 1.1 ± 1.1 young fledged per nesting effort. A male and a female provided similar amounts of parental care at a single nest. Cloacal protuberance size and amount of sperm collected did not suggest intense sperm competition among males.
