This report provides a checklist of the echiurans from the Atlantic Ocean and maps their distribution. Investigations on the taxonomy of this group since the publication of the monograph by Stephen and Edmonds (1972) on the phyla Sipuncula and Echiura have yielded two new genera, 12 new species and 13 new records. Currently the echiuran fauna of the Atlantic comprises three families, 25 genera and 63 species. The family Bonelliidae contains 35 species in 18 genera; the Echiuridae is represented by six genera and 27 species, and the Urechidae by a single species Urechis chilensis (Müller). This study shows that the Atlantic has a relatively high species diversity, comprising about 38% of the known world fauna. Bonelliids alone comprise about 56% of the echiuran fauna of the Atlantic. An analysis of distribution is given in relation to general biogeographic regions and faunistic provinces. Dichotomous keys for the identification of genera and species of echiurans from the Atlantic is provided. The North Temperate component is the richest and most diverse, making up about 68% of the Atlantic echiuran fauna; 25 species have been recorded from within the tropics; and the South Temperate component is poorly represented, with only about 19% of the total fauna. The cosmopolitan component is also poorly represented, with only four species, so far, known. Thirteen species of echiurans are provisionally considered to be endemic to the Atlantic. Members of the Echiuridae are usually shallow-water inhabitants of intertidal and subtidal zones while bonelliids exhibit a higher species richness on deeper bottoms of all oceans, mostly at depths of 1000–6000 m in the Atlantic.

This report provides a checklist of the echiuran fauna of the Indo-West Pacific Ocean and analyses their distribution in relation to general biogeographic regions. Currently the echiuran fauna of the Indo-West Pacific comprises three families, 30 genera and 103 species. The family Bonelliidae contains 43 species in 21 genera; the Echiuridae is represented by eight genera and 58 species, and the Urechidae by two species, Urechis novaezealandiae (Dendy) and U. unicinctus (von Drasche). Investigations undertaken on this group of animals after the publication of the monograph by Stephen & Edmonds (1972) on the phyla Sipuncula and Echiura have revealed one new genus, 15 new species and several new records. This study shows that the Indo-Pacific has a high species diversity, comprising about 62% of the known world fauna. The West Indian Ocean is currently represented by 28 species; 55 species have been recorded in the Central Indo-West Pacific and 53 species in the West Pacific. Only four species are thought to be cosmopolitan while approximately 50 species appear to be endemic to the Indo-West Pacific Ocean. Members of the Echiuridae are usually found in shallow-waters of littoral and subtidal zones while bonelliids are inhabitants of deeper bottoms where cold temperatures prevail.

We present new records of larvae and adult fish from the family Callionymidae in the Colombian Pacific coast. Larvae and juvenile of Synchiropus atrilabiatus (Garman 1899), expands its distribution range within this coast (between Tumaco in the South to the border with Panama in the North), presenting low to medium abundances in September-October 2002, 2003, 2004, 2005 and February-March 2006, 2014. Larvae were always collected at stations 54 km away from the coast. Adults of S. atrilabiatus were collected as bycatch from the deep-sea shrimp fishing fleet between 67-700 m depth at Bahía Cupica in 1995 and Arusí in 2005.

New data on 22 species of bees of the family Megachilidae from the North Caucasus and the south of European Russia are reported. Six species are new to Russia: Hoplitis curvipes (Morawitz, 1871), Osmia cinerea Warncke, 1988, O. ligurica Morawitz, 1868, O. cyanoxantha Pérez, 1879, Protosmia glutinosa (Giraud, 1871), and Coelioxys mielbergi Morawitz, 1880. Hoplitis turcestanica (Dalla Torre, 1896), sp. resurr. is treated as a distinct species, not a junior synonym of H. caularis (Morawitz, 1875). Megachile albocristata Smith, 1853 and M. alborufa Friese, 1911 are listed instead of previously recorded M. lefebvrei (Lepeletier de Saint-Fargeau, 1841) and M. pyrenaica (Lepeletier de Saint-Fargeau, 1841), respectively. Fourteen new regional records are reported: seven species are new to the North Caucasus, five ones are new to the south of European Russia, and two species are new to the European part of Russia as a whole. The numbers of megachilid bee species currently known in Russia, the North Caucasus, and the south of European Russia are 217, 130, and 71, respectively. The lectotype of Osmia proxima Morawitz, 1875 is designated.

In Australia the frog family Microhylidae is largely restricted to tropical rainforests of the Wet Tropics region in the north-east of the country, but in that region the family is diverse. Only one species, Cophixalus ornatus, is widespread in the WetTropics but there has been suspicion that it may comprise multiple species. A recent study (Hoskin et al. 2011) assessedgenetic and phenotypic variation across the range of C. ornatus, finding three deeply divergent genetic lineages that differin mating call and some aspects of morphology. Two of these lineages abutt in the central Wet Tropics and in that areahybridization was found to be very limited despite sympatry at high densities. Based on multiple lines of data, Hoskin etal. (2011) concluded that the three genetic lineages represent biological species. The taxonomy of these three lineages isresolved here. I describe two new species, Cophixalus australis sp. nov. and Cophixalus hinchinbrookensis sp. nov., andredescribe C. ornatus. The three species are not distinguishable based on any single morphological or call trait and arebest identified by genetics or locality. The distributions of the three species are largely allopatric. Cophixalus ornatus isfound in rainforest in the northern Wet Tropics, C. australis sp. nov. occurs in rainforest and adjacent wet sclerophyllforests in the central and southern Wet Tropics, and C. hinchinbrookensis sp. nov. inhabits rainforest and montane heathon Hinchinbrook Island. All three species are common. Cophixalus australis sp. nov. contains three genetic subgroupsthat are considered a single species based on phenotypic similarity and high levels of hybridization at contact zones. Thedescription of Cophixalus australis sp. nov. and Cophixalus hinchinbrookensis sp. nov. brings the number of Australian Cophixalus species to 18, 15 of which are restricted to the Wet Tropics region.

Urochordeumatidae Silvestri, 1909 includes a single species, Urochordeuma bumpusi Silvestri, 1909, with U. porona Chamberlin, 1941 as a new junior subjective synonym. The family Urochordeumatidae is removed from the superfamily Caseyoidea and transferred to the superfamily Striarioidea. The species is known only from four counties in Washington State in the North Cascades: Pierce, King, Thurston and Whatcom. The occurrence of U. bumpusi from Whatcom County is a significant range extension.

Abstract The Colobathristidae are a poorly studied family of Lygaeoidea distributed in the tropics and subtropics of Australasian, Neotropical, and Oriental biogeographic regions. Phaenacantha Horváth, 1904 is the largest genus of the family, with 33 described species. Here, two new species of Phaenacantha are described from Borneo (P. grimmae sp. nov. and P. nigrispina sp. nov.) and one from New Caledonia (P. paveli sp. nov.), all of which represent the first record of the genus from these islands. Also, a specimen of genus Symphylax Horváth, 1904 from Borneo is described that has strong similarities to S. handschini Kormilev, 1953 from the same island, but differs from it in some minor features and is considered a new subspecies, S. handschini kinabaluensis subsp. nov.

Few scientists have dedicated themselves to the study of Colombia’s cockroach diversity. As a result, there are large gaps in the taxonomic knowledge of Colombian cockroach fauna that make species identification difficult and little information is available on their geographic distribution. Therefore, a taxonomic study of the suborder Blattaria was undertaken by examining the literature and studying specimens available in the country’s main entomological collections. A list of genera with their respective distribution in the various biogeographic regions was obtained. Two thousand, one hundred and forty six adult specimens, distributed in 4 families, 15 subfamilies, and 47 genera were examined and identified. The material examined comes from localities belonging to 31 of the Colombian territory’s 32 departments. Distribution data were obtained for 50 genera in seven biogeographic provinces, mainly in the North Andean and Chocó-Magdalena provinces. Seven genera are presented as new records for Colombia: Buboblatta, Cahita, Cariblatta, Euthlastoblatta, Litopeltis, Macrophyllodromia and Nahublattella. The total number of cockroach genera in Colombia is raised to 61.

Sampling between 1999 and 2007 of the recent ostracod fauna of Lake Biwa, an ancient lake located in Japan, produced ten Cyprididae and one Ilyocyprididae species. One Cyprididae species, belonging to the genus Ilyodromus is described herein, Ilyodromus intermedius Okubo n. sp., and Bradleytriebella lineata (Victor & Fernando, 1981c) is redescribed. One Cyprididae species is a new record for Japan, namely Stenocypris malayica Victor & Fernando, 1981a, while seven others are new records for Lake Biwa. The family Ilyocyprididae is represented by only one species in Lake Biwa, Ilyocypris salebrosa Stepanaitys, 1960. The Lake Biwa population of this species is the first record of males and they are described in this paper. Including this study, forty ostracod species have now been reported from Lake Biwa. Most species (70%) were found at depths of less than 1 meter. Only four species were found below 44 m, the mean depth of the north basin.

SUMMARY From a consideration of the problems of plant-distribution, the writer is led to regard the history of the Angiosperms as resolving itself into two principal eras:— The era that witnessed the rise of the great families, a period of relatively uniform conditions.The era that witnessed the differentiation of these family types in response to the differentiation of the climatic and other conditions. It is argued that conclusions drawn from the prevailing influences now in operation could only be applied to the differentiation of the ancient family types–that is to say, to the second era in plant-history. It is not possible, so it is held, to apply a theory based on the present to an age of other things, other ways, and other conditions. Only the hypothesis that finds its guide to the past in the abnormalities of the present can be of service to us in the interpretation of times so different. The subject is introduced by a reference to two papers, contributed to the ‘Journal of the Linnean Society,’ which have an important bearing on the subject, the one by Bentham on the Compositæ, the other by Huxley on the Gentians. Then follows a statement of the differentiation hypothesis which involves the differentiation of primitive world-ranging types in response to the progressive differentiation of their originally uniform conditions. Allusion is then made to the dilemma into which all theorists fall when they come to handle the larger groups, the very persistence of which in our own age depends on the stability of their essential characters. If stable now, why so unstable then? We are thus forced to the conclusion that in the distant era that witnessed the deployment of the Angiosperms instability prevailed. It was an age of mutations, free and unchecked, and an age of uniformity of conditions, the mutability decreasing and the modifications becoming more and more fixed with progressive differentiation of conditions, an explanation suggested by a perusal of the accounts by Dr. Willis of his prolonged investigation on the Podostemaceæ. The distribution of families is then treated statistically; and it is shown that whilst they largely ignore the cleavage of the land into two great masses diverging from the north, they respond in a marked degree to the differentiation of the climatic zones. Behind their disregard for the present arrangement of continents and oceans lies the story of the first era, and behind their ready response to climatic differentiation lies the story of the second era. In the circumstance that the response made to the bi-cleavage of the land-mass is absent or small with the larger groups and becomes greater and greater as we go down the differentiating scale until it attains its maximum in the species, is recognised the contrast of conditions between the pre-differentiation era and the era when differentiation reigned supreme. It is held that there is a method here disclosed that could only arise by the family differentiating into the tribes, the tribe into the genera, and the genus into the species, since the opposite method of commencing with the species would produce chaos. The paper ends with the application of the statistical treatment to the larger groups behind the families, and it is shown that whilst the Dicotyledons display a much greater tendency to detachment from the tropics than the Monocotyledons, the Sympetalæ stand foremost in this respect amongst all the groups of the Dicotyledons. It may be added that there is a large amount of material in the ten tables which from considerations of space could not be discussed. These data have therefore to tell their own story
