AbstractMosquitoes of the Anopheles maculipennis complex were collected in nine provinces of Iran (Esfahan, Fars, Gilan, Golestan, Kohkiluyeh va Boyerahmad, Mazandaran, Tehran, Azarbaijan-e Gharbi and Zanjan) between June 1983 and September 2002. The nuclear rDNA ITS2 sequences of 86 specimens were compared with those of seven species of the complex available in GenBank. Three genetically distinct species of the complex were distinguished: A. maculipennis Meigen, A. sacharovi Favre and a previously unrecognized species. The last species is most similar to, but clearly distinct from, A. martinius Shingarev and A. sacharovi. The taxonomy of A. martinius and A. sacharovi is critically reviewed, and justification is provided for formally recognizing the third species as Anopheles persiensissp.n. The new species is the first culicid to be characterized and named principally on the basis of DNA evidence. Anopheles persiensis was collected only in the northern Caspian Sea littoral provinces of Gilan and Mazandaran, and it seems likely that this species could be responsible for malaria transmission in this region that was previously attributed to A. maculipennis. A species-specific RFLP–PCR assay based on ITS2 sequences was developed to facilitate further studies of the three species in Iran.

A diagnostic polymerase chain reaction [PCR] assay using species-specific primers and direct sequencing was used to identify members of the Anopheles maculipennis complex in the north-west and central regions of the Islamic Republic of Iran. Specimens were collected from 9 provinces during 2 seasonal activities in 2001-2002, identified morphologically and subjected to PCR assay and direct sequencing. Results showed that only 2 species, An. maculipennis Meigen, and An. sacharovi Faver, were present in the area of study. This was confirmed by the high similarity [99.2%-100%] of their sequences with those available in GenBank. The molecular data and relative distribution of these species in relation to their vectorial capacity and the epidemiology of malaria in the region are discussed

The family Botryosphaeriaceae encompasses important plant-associated pathogens, endophytes and saprobes with a wide geographical and host distribution. Two dark-spored botryosphaeriaceous taxa associated with Rhus typhina dieback and canker disease were collected from Ningxia Province, in northwestern China. Morphology and multigene analysis (ITS, LSU and EF-1α) clearly distinguished this clade as a distinct species in the genus. Phaeobotryon rhois is introduced and illustrated as a new species in this paper. The species is characterized by its globose, unilocular fruiting bodies and small, brown, 1-septate conidia. It can be distinguished from the similar species P. cercidis, P. cupressi, P. mamane and P. quercicola based on host association and conidial size and colour.

The genus Cicadulina was established in 1926 (Bull. Ent. Res. 17, p. 43) to hold a new species, C. zeae, China, injurious to maize in Kenya Colony. Later (Bull. Ent. Res., 19, 1928, p. 66) it was shown that Balclutha mbila, Naude, recorded as transmitting the virus of streak disease of maize in Natal, also belonged to this genus, and two new species C. arachidis and C. similis were described from the Gambia, where they were reported as injurious to ground-nut and suspected of transmitting the virus of the rosette disease of that plant. Since that time Dr. H. H. Storey of the Amani Research Station has been investigating the possibility of transmission of the streak virus of maize by C. zeae. In attempting to breed strains capable of transmission of the disease certain crosses were made which showed conclusively that he was dealing with two distinct species. These species he was able to separate on the colour pattern of the abdomen. Dr. Storey has now sent to me material of both these species and a study of the genitalia corroborates his finding. One, of course, proved to be C. zeae, the other is new and I therefore propose to dedicate it to the discoverer.

Three endemic species of Xyris (Xyridaceae, Poales) are currently recognized in New Caledonia. A recent multivariate analysis of 18 morphological characters based on 129 specimens of Xyris from New Caledonia, supported by 10 anatomical and micromorphological observations, suggested that three species should be recognized in the New Caledonian archipelago. However, the three published names did not correspond to the three entities identified via the multivariate analyses. The results showed that Xyris neocaledonia Rendle was morphologically distinct but requires lectotypification, Xyris guillauminii Conert was indistinct from X. pancheri Rendle, and that a new morphologically distinct species required description. We therefore propose to clarify the taxonomy of the genus for New Caledonia, by designating a lectotype, making this synonymy and describing the new species. The new species, Xyris desquamatus J.R.Morel & Munzinger, sp. nov., has the remarkable feature of leaves that are shed as the plant senesces, and is reflected in the specific epithet for this new species. Line drawings are provided for the new species, along with colour photos for the three New Caledonian Xyris species and a distribution map. Three identification keys are provided, the first based on vegetative characters, the second on reproductive characters and the third on anatomical features of the leaf. Xyris desquamatus is preliminarily assigned an IUCN risk of extinction assessment of vulnerable.

In this study, we describe a new orchid species, Goodyera malipoensis, from Yunnan, China. We have performed morphological and molecular analyses on this new species. A detailed comparison between the newly discovered orchid and other members of Goodyera was conducted. The new plant is characterized by having a dense brownish green pubescence on the peduncle. Its ovate-lanceolate petal is unique in Goodyera genus. The hypochile is deeply concave-saccate, and inside there are two papillose rows on each side. These features distinguish the new orchid from all other known species of Goodyera. The molecular study based on nuclear ribosomal ITS sequence data and morphological differences support G. malipoensis as a distinct species.

Vellozia leptopetala corresponds to V. epidendroides, a much older name, and its taxonomic history encompass also V. epidendroides var. divaricata and V. epidendroides var. major, which are quite distinct species. For solving this situation, new synonyms of V. epidendroides, a new name, V. ornithophila, and a new status for both varieties of V. epidendroides are here presented. Vellozia virgata corresponds to V. sellowii, also a much older name. For solving this situation, the sinking of V. virgata into V. sellowii, and a new species, V. linearis, based on the isotypes of V. virgata, are presented. Vellozia asperula var. filifolia showed to be a very distinct species from V. asperula. For mending this situation, a new status for V. asperula var. filifolia is proposed.

Based on morphological and phylogenetic studies, Selaginella qingchengshanensis, a new species in S. sect. Heterostachys from Sichuan, China is described and illustrated. Morphologically, the new species is similar to S. amblyphylla, but has sterile leaves with denticulate to slightly ciliate margins, dorsal leaves with long arista (as long as leaves) perpendicular to stems and branches in living plants, and axillary leaves triangular-ovate or broadly ovate. Molecular analyses based on ITS+5.8S and rbcL data also support it as a distinct species.

Surveys of the freshwater crabs of two islands in the Gulf of Guinea, Central Africa, allowed a revision of the taxonomy of two little-known island endemic species, based for the first time on adult males: Potamonautes margaritarius (A. Milne-Edwards, 1869) from São Tomé, and of P. principe Cumberlidge, Clark and Baillie, 2002, from Príncipe (Brachyura; Potamonautidae). A new species of Potamonautes from southern São Tomé (Potamonautes saotome sp. nov.) is also described that is genetically distinct and has a clearly separate geographic distribution from P. margaritarius from northern São Tomé. The new species from southern São Tomé can be recognized by a suite of characters of the carapace, thoracic sternum, and gonopods. The taxonomy of P. margaritarius (A. Milne-Edwards, 1869) is stabilized by selecting a neotype from northern São Tomé. Potamonautes principe from Príncipe is the most distinct of the three taxa, with a more swollen carapace that has smooth anterolateral margins, and a shorter, straighter male first gonopod. All three taxa are morphologically distinct species that have also been clearly distinguished as evolutionarily separate lineages by mtDNA analysis and haplotyping in an earlier study. Previous phylogenetic evidence supports two separate island colonization events at different times in the past from different ancestral populations, one to São Tomé and another to Príncipe that resulted in the establishment of the endemic freshwater crab faunas of these two islands.
