ABSTRACT A previously unknown chemolithoautotrophic arsenite-oxidizing bacterium has been isolated from a gold mine in the Northern Territory of Australia. The organism, designated NT-26, was found to be a gram-negative motile rod with two subterminal flagella. In a minimal medium containing only arsenite as the electron donor (5 mM), oxygen as the electron acceptor, and carbon dioxide-bicarbonate as the carbon source, the doubling time for chemolithoautotrophic growth was 7.6 h. Arsenite oxidation was found to be catalyzed by a periplasmic arsenite oxidase (optimum pH, 5.5). Based upon 16S rDNA phylogenetic sequence analysis, NT-26 belongs to theAgrobacterium/Rhizobium branch of the α-Proteobacteria and may represent a new species. This recently discovered organism is the most rapidly growing chemolithoautotrophic arsenite oxidizer known.

A New Species

A new tribe of the Conocephalinae, Armadillagraeciini Rentz, Su, Ueshima is described to include three known Australiangenera: Armadillagraecia, Kapalgagraecia and Lichenagraecia gen. nov. Lichenagraecia gen. nov. is the eastern repre-sentative of the tribe, the others from the Northern Territory, northern Western Australia and western Queensland. Threenew genera in the tribe Agraeciini are described from the rainforests of north-eastern Queensland, Australia. Ingrischa-graecia gen. nov. is known from a single species, I. iterika sp. nov. Emeraldagraecia gen. nov. is known from two spe-cies, E. munggarifrons and E. windsorana spp. nov. Miniagraecia gen. nov. is described from two species: M. milyali andM. goorijupa spp. nov. In the Listroscelidinae; Requenini, a new species of the previously monotypic genus Xingbaoia,X. irvineorum sp. nov. is described from two localities in peril from repeated prescribed burning. Distribution maps, keys, measurements, song patterns and cytological observations are provided for most species.

This paper is part of the “Goblin Spider PBI” project, a world-wide revision of the spider family Oonopidae (http:// research.amnh.org/oonopidae). Oonopidae is one of the world’s most diverse spider families with over 1000 described species in 88 genera (Platnick 2012). Mostly six-eyed and tiny (1–3 mm), they are not often noticed by people because of their small size and secretive lifestyle. Most have a body shield of abdominal scutae (hardened plates). The Oonopidae are most diverse in tropical and subtropical regions (Platnick and Dupérré 2010), yet they also occur in other locations such as at high altitudes in the Himalayan Mountains (Baehr and Ubick 2010).

A New Species

Cladonema timmsii, sp. nov., is described from Blue Lagoon, an inland saline lake on Eyre Peninsula, near Cactus Beach, due south of Penong, Australia. It is a small medusa with a bell height and diameter of about 2.0mm. It differs from its congeners in having (1) sexually dimorphic gonads, i.e., the males bearing six radially arranged gonadal pouches on the stomach wall, the females lacking gonadal pouches, having instead smooth gonads; (2) different arrangements of nematocyst warts on the main tentacle branches (two rows) and side branches (one row). It is further characterized by having (1) nine simple radial canals, each corresponding with a tentacle bulb bearing a 7-branched stinging tentacle and about six suctorial branches; (2) six oral tentacles with very short stalks, each bearing a terminal nematocyst knob; (3) dark red, lensed ocelli. This is the first report of a species of Cladonema from Australian waters; members of the genus are also reported herein from the Northern Territory and New South Wales.

A New Species

A bush tomato that has evaded classification by solanologists for decades has been identified and is described as a new species belonging to the Australian “Solanumdioicum group” of the Ord Victoria Plain biogeographic region in the monsoon tropics of the Northern Territory. Although now recognised to be andromonoecious, S.plastisexum Martine & McDonnell, sp. nov. exhibits multiple reproductive phenotypes, with solitary perfect flowers, a few staminate flowers or with cymes composed of a basal hermaphrodite and an extended rachis of several to many staminate flowers. When in fruit, the distal rachis may abcise and drop. A member of SolanumsubgenusLeptostemonum, Solanumplastisexum is allied to the S.eburneum Symon species group. Morphometric analyses presented here reveal that S.plastisexum differs statistically from all of its closest relatives including S.eburneum, S.diversiflorum F. Meull., S.jobsonii Martine, J.Cantley & L.M.Lacey, S.succosum A.R.Bean & Albr. and S.watneyi Martine & Frawley in both reproductive and vegetative characters. We present evidence supporting the recognition of S.plastisexum as a distinctive entity, a description of the species, representative photographs, a map showing the distribution of members of the S.eburneum species group and a key to the andromonoecious Solanum species of the Northern Territory of Australia. This new species is apparently labile in its reproductive expression, lending to its epithet, and is a model for the sort of sexual fluidity that is present throughout the plant kingdom.
