Analysis of Andes frogs (Phrynopus, Leptodactylidae, Anura) phylogeny based on 12S and 16S mitochondrial rDNA sequences

South American leptodactylid frogs of the genus Phrynopus occur in cloud-forest, páramo, subpáramo and puna habitats (1000–4400 m elevation) from Colombia to Bolivia. Currently, there are 34 described species; however, many additional species new to science have been reported from Colombia, Peru, and Bolivia. The phylogeny of the species-diverse Phrynopus is unknown and the position of the genus within Leptodactylidae is poorly understood. We present the results of a phylogenetic study based on 12S and 16S mitochondrial rDNA. Fifteen species of Phrynopus from Bolivia to Ecuador are included, along with several other genera of Leptodactylidae and representatives of other frog families. Our results indicate that Phrynopus is phylogenetically nested within Eleutherodactylus , whereas Phyllonastes is phylogenetically nested within Phrynopus . Based on the recovered phylogeny, we transfer Phrynopus simonsii to Eleutherodactylus , and show that Phrynopus carpish needs to be removed from Phrynopus . Eleven of the 13 Phrynopus species occurring in Central Peru share the absence of an external and internal ear.     

Three new species of Tigridia (Iridaceae) from Mexico

Tigridia durangense, T. chiapensis, andT. huajuapanensis are described as new. The first species is known from llanos near La Ciudad and El Salto, Durango ; the second from the highlands of central Chiapas; and the third from a single locality near Huajuapan de León, Oaxaca.     

Four new species of the Didymopanax group of <Emphasis Type="Italic">Schefflera</Emphasis> (Araliaceae) from the Brazilian Amazon

Four new species of the Didymopanax group of Neotropical Schefflera (Araliaceae) from the Brazilian Amazon are here described and illustrated. Two of these are mainly known from the surroundings of Manaus, Amazonas state (Schefflera ciliatifolia and Schefflera umbrosa). The first is distinguished by its ciliate leaflets, while the second is characterized by leaflets varying in shape from trilobed to entire. Schefflera plurifolia is known only from southern Amazonian forests, and is remarkable in its pinnately-compound leaflets. Schefflera dichotoma, only known from the type collected on “campinarana” forests from Upper Rio Negro, at the municipality of São Gabriel da Cachoeira (Amazonas), is characterized by dichotomously branching inflorescences. Comments on the geographic distribution and ecology of the new species are provided, as well as an identification key to the species of the Didymopanax group found in Brazilian Amazonian rainforests and savannas.     

Studies in neotropical polypores 15: new and interesting species from Guyana

During fieldwork in Guyana several unusual and distinctive taxa of polypores were collected, three of which are described here as new. The first of these, Amauroderma coltricioides is the first species known in the Ganodermataceae with smooth basidiospores. Coltricia verrucata and Coltriciella navispora also are described as new, and a key to the neotropical species of Coltricia is provided. Finally, a checklist of 73 poroid fungi from Guyana is given, of which 29 are new records for the country.     

A well-preserved aneuretopsychid from the Jehol Biota of China (Insecta, Mecoptera, Aneuretopsychidae)

The Aneuretopsychidae is an unspeciose and enigmatic family of long-proboscid insects that presently consist of one known genus and three species from the Late Jurassic to Early Cretaceous of north-central Asia. In this paper, a new genus and species of fossil aneuretopsychid is described and illustrated, Jeholopsyche liaoningensisgen. et sp. n. Fossils representing this new taxon were collected from mid Early Cretaceous strata of the well known Jehol Biota in Liaoning Province, China. This finding documents the first formal record of fossil Aneuretopsychidae in China. In addition, this well-preserved and new material reveals previously unknown and detailed morphological structure of the mouthparts, antennae, head, thorax, legs and abdomen of this distinctive insect lineage.     

Notes on the Burseraceae in central Amazonia,including four new taxa. Studies in neotropical Burseraceae XXVI

The Burseraceae are known to comprise one of the most important tree families in Amazonia, but examination of Burseraceae diversity indicates that this importance is achieved differently in different parts of the Amazon, generally showing greater relative density compared to relative diversity in the east and greater relative diversity compared to relative density in the west, but both high relative density and diversity in central Amazonia. The patterns of relative density may be explained by current climates and by soils, but those of diversity are more likely a function of historical events. Revision of the Burseraceae for two projects near Manaus, Brazil revealed four new taxa. Protium hebetatum is widespread in western Amazonia, but it is one of the most common trees in central and west-central Amazonia; it resembles P. grandifolium. Protium tonyanum is a distinctive new species in poorly resolved sect. Sarcoprotium. Protium paniculatum var. modestum is known thus far only from the vicinity of Manaus plus several localities in the state of Amazonas, Venezuela; a key to the varieties is provided. Dacryodes hopkinsii is one of a group of four species in that genus from Amazonia and the Venezuelan Guayana with relatively large and fleshy flowers that are functionally bisexual. The discovery of these new taxa underscores the biological importance of Manaus and vicinity as a center of diversity for many taxa and exemplifies the synergy between well-designed floristic projects and systematics.     

A new Hesperodiaptomus Light (Copepoda, Calanoida, Diaptomidae) from Mexico with comments on the distribution of the genus

A new species of the freshwater planktonic copepod genus Hesperodiaptomusis described from material collected in several water bodiesin the state of Morelos, central Mexico. Hesperodiaptomus morelensisn. sp. differs from its congeners in having a very reduced endopodon the male fifth right leg, and a hook-shaped cuticular processon the inner margin of the first exopodal segment of the sameleg. Besides other characters of the female fifth legs, thenew species has a distinctive genital somite, with asymmetricallateral wing-like processes. This species seems to be closelyrelated to H. kiseri mainly because of similarities betweenthe male fifth legs and the structure of the female genitalsomite. This predominantly nearctic genus is known to be distributedmainly in north-western and central North America, althougha few species have been recorded in north-eastern Asia (Siberia).Hesperodiaptomus has not been recorded previously south of California.Apparently, this genus radiated in North America and spreadin different directions. The apparent disjunct distributionof at least two species (including the new one) could be explainedas resulting from a previous extensive radiation related toglaciation and consequent post-glacial repopulation that mighthave left these forms as stranded remnants, or by dispersalprocesses: central Mexico is connected with North America bytwo high-altitude potential passages. The new species seemsto be restricted to a high altitude area in Mexico. It seemsunlikely that species of Hesperodiaptomus will be recorded furthersouth on the American continent.     

Bryoerythrophyllum duellii Blockeel (Bryophyta: Pottiaceae), a new moss species from Greece and Cyprus,and its molecular affinities

A moss first collected on Crete by Prof. Ruprecht Düll in 1976 but never satisfactorily identified is described as a new species, Bryoerythrophyllum duellii. It is known from five localities in Greece and Cyprus. It belongs to the B. recurvirostrum group, and its status as a distinct taxon is supported by molecular data. The molecular relationships of the genus Bryoerythrophyllum are discussed, and they suggest that the genus is monophyletic only if Erythrophyllopsis, Mironia and Saitobryum are included. The B. recurvirostrum and B. wallichii groups apparently form a young complex of taxa that are not very diverse molecularly, but sometimes have a distinctive morphology. Bryoerythrophyllum duellii is one of several lineages within this complex that may have experienced a longer period of reproductive isolation leading to the fixation of distinctive morphological and molecular features.     

The genus Argulus (Crustacea: Branchiura) in Africa: two new species,A. fryeri and A. gracilis,the previously undescribed male of A. brachypeltis Fryer and the identity of the male described as A. ambloplites Wilson

Two new species of Argulus Müller, 1785 (Crustacea: Branchiura) are described from Africa. A. fryeri n. sp., parasitic on an unknown fish species collected from Lake Turkana, Kenya, is characterised by: deep antero-lateral depressions which delimit a pronounced frontal region; robust, square second maxillae ornamented with numerous small, simple scales; and the shape of the respiratory areas. The most distinctive features of A. gracilis n. sp., parasitic on Auchenoglanis occidentalis var. tanganicanus collected from Lake Tanganyika, are the anterior spines on the first antennae and the shape of the respiratory areas. A. brachypeltis Fryer, previously known only from the female, is characterised by: a narrow, elongate body with foreshortened carapace lobes; small, slender terminal spines on the first antennae; and short terminal segments on the second maxillae with minute claws. The identity of the male described as A. ambloplites Wilson is discussed and renamed A. confusus nom. nov.     

New fossil anthropoids from the middle Miocene of East Africa and their bearing on the origin of the oreopithecidae

Recent paleontological collections at the middle Miocene locality of Maboko Island in Kenya, dated at 15-16 million years, have yielded numerous new specimens belonging to at least five species of fossil anthropoids. The most common species of ape at the site, a medium-sized primate with a very distinctive dental morphology, clearly represents a previously undescribed taxon. When compared with other Miocene anthropoids from East Africa, it has its closest affinities with the poorly known species Rangwapithecus vancouveringi from the early Miocene locality of Rusinga Island. The species from Maboko Island is described here as belonging to a new genus of fossil anthropoid, to which "Rangwapithecus" vancouveringi is also referred. The new genus has a highly distinctive suite of derived characters of its molars and premolars, which it shares with Oreopithecus bambolii from the late Miocene of Europe. These synapomorphies indicate a close phyletic relationship between the East African species and Oreopithecus and form the basis for the inclusion of these taxa in a single family, the Oreopithecidae Schwalbe, 1915. In many respects, however, the East African forms are more conservative than Oreopithecus, and in a general sense they can be regarded as an intermediate grade between Oreopithecus and the more generalized early Miocene catarrhines, the proconsuloids. There is, therefore, good fossil evidence to indicate that the origins of the Oreopithecidae can be traced back to the early Miocene of Africa.     

Stiphodon niraikanaiensis,a new species of sicydiine goby from Okinawa Island (Gobiidae: Sicydiinae)

A new goby species, Stiphodon niraikanaiensis, is described on the basis of three specimens (two females and one male) collected from a freshwater stream in Okinawa Island, Japan. This species can be distinguished from its congeners by nine soft rays in the second dorsal fin, 16 rays in the pectoral fin, a pointed first dorsal fin in male, the premaxilla with 46–50 tricuspid teeth in 27–36 mm SL; no white patch behind the pectoral-fin base in male, the nape and posterior half of the occipital region covered by cycloid scales, broad black band along the distal margin of the second dorsal fin in male, 11 or 12 dusky transverse bars laterally on the trunk and tail of female intersecting with the mid-lateral longitudinal band, several conspicuous black spots on each spine and soft ray on the first and second dorsal fins of female, the anal fin of female lacking remarkable marking, and the pectoral-fin rays with 2–5 and 1–4 black spots, respectively, for male and female. The new species is known only from the type locality.     

Simulium (Psilopelmia) virescens, a new black-fly species (Diptera: Simuliidae) from the southwestern region of the state of Bahia, Brazil

The last-instar larva, pupa, male and female of Simulium virescens sp. nov. are described and illustrated. This species has a peculiar larva, which has an elongated head capsule and light-green colour. The first thoracic segment has tubercle on its dorsal region and the third thoracic segment has one pair of tubercles; the first to the fourth abdominal segments have one pair of tubercles on each segment. Until now this new species had only been collected at the type locality, which is on the middle stretch of the Correntina River in the southwestern portion of the state of Bahia, Brazil. Females were voraciously biting humans during the field work. This new species represents the second species of Simulium (Psilopelmia) in Brazil and the first registered outside of the Brazilian Amazon Region.     

Biology and defensive adaptations in Rodatus major (Coleoptera: Coccinellidae) and its prey, Monophlebulus pilosior (Hemiptera: Margarodidae)

The biology of the Australian coccinellid Rodatus major (Blackburn) and its prey, the hemipteran margarodid Monophlebulus pilosior (Maskell), are described. New predators and a new parasite of M. pilosior are recorded. Rodatus major makes use of elaborate and distinctive defensive adaptations and behaviour to protect itself from predators. They include cryptic coloration, aposematic behaviour, production of wax by larvae, production of a large, thick protective covering concealing the pupa and resembling an M. pilosior ovisac, and reflex bleeding. It is the only known coccinellid species in which both prepupa and pupa are hidden by a protective shroud of wax threads. Rodatus major has a specialized feeding behaviour. Its potential as a biological control agent is assessed. It is only the second Australian margarodid-feeding coccinellid to be studied, Rodolia cardinalis (Mulsant) being the first.     

Contributions to the faunistics and bionomics of Staphylinidae (Coleoptera) in northeastern North America: discoveries made through study of the University of Guelph Insect Collection, Ontario, Canada

Staphylinidae (Rove Beetles) from northeastern North America deposited in the University of Guelph Insect Collection (Ontario, Canada) were curated from 2008-2010 by the first author. The identification of this material has resulted in the recognition of thirty-five new provincial or state records, six new Canadian records, one new record for the United States and two new records for eastern Canada. All records are for subfamilies other than Aleocharinae and Pselaphinae, which will be treated in future publications as collaborative projects. Range expansions of ten exotic species to additional provinces and states are reported. The known distributions of each species in northeastern North America are summarized and presented as maps, and those species with a distinctive habitus are illustrated with color photographs. Genitalia and/or secondary sexual characters are illustrated for those species currently only identifiable on the basis of dissected males. The majority of the new records are in groups that have been recently revised, demonstrating the importance of curation and local insect surveys to the understanding of biodiversity, even for taxa and areas considered 'relatively well-known'.     

Description of two new species of Clivina Latreille (Coleoptera, Carabidae, Clivinini) from southeastern United States

Two new species of the genus Clivina Latreille are described. One, Clivina choatei Bousquet & Skelley, belongs to the nominotypical subgenus and is known from six specimens collected in northern Florida. The species is structurally similar to Clivina myops Bousquet, known only from the holotype found in North Carolina, but differs among others by its smaller size and wider elytral striae. The second species, Clivina alabama Bousquet, belongs to the subgenus Antroforceps Barr and is known from two specimens collected in north-central Alabama. The species is structurally most similar to Clivina sasajii Ball, known only from Latimer County in Oklahoma, but differs among others in the absence of eyes and in having the pronotum and elytra proportionally wider.     

HALIMEDA HUMMII SP. NOV., HALIMEDA CRYPTICA V. ACERIFOLIA VAR. NOV. (CAULERPALES,CHLOROPHYTA), AND ADDITIONAL RECORDS OF HALIMEDA SPECIES FROM: PUERTO RICO1

A new species, Halimeda hummii, and a new variety of Halimeda cryptica Colinvaux and Graham both originally collected from the edge of the continental shelf on the southwest coast of Puerto Rico are newly described. The new species is irregular in its segment morphology and is the smallest species of Halimeda presently known. Halimeda cryptica var. acerifolia from deep water possesses distinctive segments resembling maple leaves. Halimeda copiosa Goreau and Graham and typical H. cryptica are also collected in deep water and are newly recorded from Puerto Rico.
