The taxonomy of Petrogale has been in a state of flux for many years. The eight chromosome races of the eastern Petrogale radiation are currently placed in four species. However, several of these 'species' contain chromosomally unrelated taxa. In this paper a species definition for Petrogale is proposed that allows for some gene flow between species but requires a species to maintain a substantial and distinct genetic identity. When this definition was applied to the eastern Petrogale eight 'good' species were identified. Thus we now consider the eastern Petrogale complex to consist of P. penicillata, P. herberti (formerly P. penicillata herberti), P. inornata, P. assimilis, P. sharmani, sp. nov. (formerly the Mt Claro race), P. mareeba, sp. nov. (formerly the Mareeba race), P. godmani and P. coenensis, sp. nov. (formerly the Cape York race). Several of these taxa are cryptic species and the primary means of identification used was chromosome number and morphology. However, genic data were useful in establishing whether each taxon should be regarded as a separate species.

A New Species

Cytological and morphological study of subterranean clovers in Israel has shown that the previously reported 2n = 12 Israeli "chromosomal race" or "cryptic species" is actually morphologically quite distinct from 2n = 16 Trifolium subterraneum L. Both on morphological and genetical grounds the "Israeli race", with chromosome number 2n = 12, should be regarded as a distinct species. It is described in the present paper as a new species, Trifolium israeliticum. The paper includes data on the distribution of the two subterranean clovers in Israel.

Three new species are described in the genus Drymopsalta Ewart, previously known only from D. crepitum Ewart and D. daemeli Distant. The three new species occur in Southern Queensland and Northern Territory. D. wallumi sp. nov. occurs along coastal S.E. Queensland, whereas D. hobsoni sp. nov. is restricted to the Bringalily State Forest, near Inglewood, southern inland Queensland. D. acrotela sp. nov. is found in the Litchfield National Park and other locations near Jabaluka, Cahills Crossing, E. Alligator River and Nourlangie, all across the northern Northern Territory. D. crepitum occurs on the Cape York Peninsular extending into the southern Gulf, while D. daemeli occurs in two localised regions in central coastal N.S.W. Each of the species inhabits heath vegetation, often spilling-over into adjacent tree foliage. The species of Drymopsalta are small and inconspicuous cicadas (<15 mm body length) with relatively high frequency songs (~15 to 22 kHz). The temporal structures of the normal calling songs follow a similar pattern in each species, consisting of the emission of short chirps (comprising 2–16 ticks). Between the chirps are emitted one (D. wallumi, D. hobsoni, D. acrotela), two (D. daemeli) or 1–9 (D. crepitum) intervening single ticks. The species can be distinguished by the timing and the number of these single ticks relative to the adjacent chirps with the notable exception of D. hobsoni and D. acrotela. The calling songs of these two allopatric species are indistinguishable, an unusual feature in Australian cicadas. Two additional song variants are described, a more unstructured chirping song without intervening single ticks observed in each of the species except D. crepitum, and periodic extended buzzing echemes emitted within the calling songs (excepting the D. wallumi song).

Medicago Rigidula

European and Asian plants assignable to Medicago rigidula (L.) All., as this species is currently interpreted, were found to differ morphologically. Indeed, a combination of morphological, geographical, and interbreeding evidence supports the recognition of the European and Asian plants presently interpreted as M. rigidula as separate species. The best characters for distinguishing plants of the two continents are number of pollen pores (pollen consistently 3-pored in European plants, and consistently 4-pored in Asian plants), number of coils in the pod (averaging 4.5 in European plants, 5.5 in Asian), and fruit spine morphology (usually more hooked and longer in European compared to Asian plants). Plants of North Africa require further study, but the specimens examined were generally closer to European than to Asian plants. The chromosome number of 28 Asian collections, 24 European collections, and 3 African collections was constant, with n = 7.

A New Species

Aspidistra revoluta (Asparagaceae) is described and illustrated as a new species from limestone areas in southern Chongqing Municipality, China. The new species can be distinguished from the other Aspidistra species by its unique umbrella-like pistil with large revolute stigma lobes that bent downwards and touch the base of the perigone. A detailed morphological comparison among A. revoluta, A. nanchuanensis and A. carnosa is provided. The pollen grains of A. revoluta are subspherical and inaperturate, with verrucous exine. The chromosome number is 2n = 38, and the karyotype is formulated as 2n = 22m + 6sm + 10st. The average length of chromosome complement is 4.50 μm, and the karyotype asymmetry indexes A1 and A2 are respectively 0.37±0.03 and 0.49±0.01.

New Synonymy

The genus Nirmides Hering, 1931 is revised. Nowadays it includes 17 species, known from Thailand, Vietnam and the Andamans to the Philippines. Eight species are described as new to science: N. siamasp. n. (Thailand), N. ihleisp. n. (Thailand), N. dianasp. n. (Andaman Islands), N. samaressp. n. (Philippines, Samar), N. lourensisp. n. (Philippines, Luzon), N. similissp. n. (Philippines, Mindanao), N. kanlaonensissp. n. (Philippines, Negros), and N. hollowayisp. n. (Borneo). Lectotypes are designated for Susica basalis Walker, 1862 and Nirmides basalis f. fusca Hering, 1931. The taxon Nirma micron van Eecke, 1929 is removed from synonymy with Nirmides basalis (Walker, 1862) and restored to a separate species. A new synonymy is proposed: Nirmides micron (van Eecke, 1929) = Nirmides manwahi Holloway, 1990, syn. n. The homology of the sclerites of the male genitalia is discussed; the musculature of the male genitalia is examined. A key to species is given.

A New Species

The Atlantic Forest of Brazil includes one of the highest species diversity and endemism in the planet, representing a priority for biodiversity conservation. A new species of Anemopaegma from the Atlantic Forest of Brazil is here described, illustrated and compared to its closest relatives. Anemopaegma nebulosum Firetti-Leggieri & L.G. Lohmann has been traditionally treated as a morph of Anemopaegma prostratum; however, additional morphological and anatomical studies indicated that A. nebulosum differs significantly from A. prostratum and is best treated as a separate species. More specifically, A. nebulosum is characterized by elliptic and coriaceous leaflets (vs. ovate to orbicular and membranaceous in A. prostratum), smaller leaflet blades (3.6–5.5 x 2.0–3.0 cm vs. 6.7–13.0 x 4.2–8.4 cm in A. prostratum), orbicular prophylls of the axillary buds (vs. no prophylls in A. prostratum), solitary flowers (vs. multi-flowered axillary racemes in A. prostratum) and a gibbous corolla (vs. infundibuliform corollas in A. prostratum). In addition, A. nebulosum differs from A. prostratum anatomically in having thicker leaflet blades composed of two to four layers of palisade parenchyma (vs. one to three layers in A. prostratum), and seven to eight layers in the spongy parenchyma (vs. six to eight layers in A. prostratum). A key for the identification of all species of Anemopaegma from the Atlantic Forest of Brazil is presented.

Efficient Sequence

DNA barcoding has been recently promoted as a method for both assigning specimens to known species and for discovering new and cryptic species. Here we test both the potential and the limitations of DNA barcodes by analysing a group of well-studied organisms—the primates. Our results show that DNA barcodes provide enough information to efficiently identify and delineate primate species, but that they cannot reliably uncover many of the deeper phylogenetic relationships. Our conclusion is that these short DNA sequences do not contain enough information to build reliable molecular phylogenies or define new species, but that they can provide efficient sequence tags for assigning unknown specimens to known species. As such, DNA barcoding provides enormous potential for use in global biodiversity studies.Key words: DNA barcoding, species identification, primate, biodiversity.
