The genus Ips in North America contains several groups of closely related species which are at present poorly defined. Morphological characters alone do not provide an adequate basis for deciding whether some of the forms are specifically distinct or represent mere variations which may occur in the same general locality or even in the same brood. The extent of this variation can be determined only by breeding isolated pairs through successive generations combined with biological studies in the field. The present article describes techniques for rearing successive generations of Ips in the laboratory.

We describe Sphagnum incundum in Sphagnum subgenus Acutifolia (Sphagnaceae, Bryophyta). We used both molecular and morphological methods to describe the new species. Molecular relationships with closely related species were explored based on microsatellites and nuclear and plastid DNA sequences. The morphological description is based on qualitative examination of morphological characters and measurements of leaves and hyalocysts. Morphological characters are compared between closely related species. The results from Feulgen densitometry and microsatellite analysis show that S. incundum is gametophytically haploid. Molecular analyses show that it is a close relative to S. flavicomans, S. subfulvum and S. subnitens, but differs both genetically and in morphological key characters, justifying the description of S. incundum as a new species. The new peatmoss is found in North America along the western coast of Greenland, in Canada from Quebec and Northwest Territories, and Alaska (United States). The new species has a boreal to arctic distribution.

Cladophorus Guérin-Méneville, 1830 are endemic Papuan net-winged beetles which take part in highly diverse Müllerian mimicry rings. Available specimens were sequenced for cox1–tRNA-Leu–cox2 mitochondrial DNA fragment and the species delimitations were based on the genetic distance, phylogenetic analysis, and morphology. Three earlier described species were identified in the recently collected material and further 10 species are described: C. pallescens sp. nov., C. bicolor sp. nov., C. craterensis sp. nov., C. motykai sp. nov., C. mindikensis sp. nov., C. kailakiensis sp. nov., C. manokwarensis sp. nov., C. haiaensis sp. nov., C. humeralis sp. nov., and C. boceki sp. nov. DNA-based identifications provided some ambiguous results and closely related species could not be robustly delimited using solely molecular data. Additionally, the species limits were based on clearly defined morphological characters and the morphological differentiation was found unlinked from the genetic divergence. Colour patterns cannot be used for identification because all species available in more specimens were polymorphic and followed various local co-mimics. The Papuan fauna of Cladophorus is very diverse and the closely related species regularly occur in limited regions. Differentiation within restricted ranges is therefore considered as the main speciation mode.

AbstractThe genus Ips is one of four closely related genera in the tribe Ipini, sub-tribe Ipina (De Geer 1775, Balachowsky 1949, Nunberg 1954, Hopping 1963). There are now 32 species of Ips recognized in North America, with a few more as yet undescribed. This paper defines the groups of closely related species with observations on the group relationships of species from other parts of the world. Work is in progress to define the North American species in each group.

The complete series of larval staging of Hippolyte sapphica d’Udekem d’Acoz, 1993 forma A and B from Louros estuary was studied in the laboratory and described in detail for the first time. The reared larvae of H. sapphica passed through six zoeal stages and one megalopal stage. The larval monitoring completed when the individuals could be assigned clearly to form A and B via rostra formation. Under the experimental conditions, the average durations of the larval stages were as follows: three days for 1 st and 2 nd stages, three to four days for 3 rd , 4 th , 5 th and 6 th stages, four days for the megalopal stage and 19 to 30 days for immature form A and B individuals. Comparison of the larval morphological characters among the described material and the bibliographic data of closely related species was made and discussed. The offspring of females of the forma A includes forma A and B and the same can be said of the offspring of the forma B. This confirms that the formae A and B are indeed conspecific.

A new species for the genus Isophya, I. bumerangoides, is described from the Northeastern Black Sea Region of Turkey. Thenew species differs from closely related species in some aspects of morphology, mainly in male and female genitalia. Illustra-tions of external morphological characters and male and female songs are provided. Additional data on male calling song andfemale song of closely related bush-cricket Isophya rizeensis Sevgili, 2003 are also given. Scanning Electron Microscopeimages of stridulatory file of the other related species I. redtenbacheri Adelung, 1907 are provided. I. bumerangoides clearlybelongs to I. amplipennis group. Our bioacoustic results suggest that within the genus Isophya, changes in calling song seem to appear more slowly than those in external morphological characters as in most tettigoniid.

The discovery of a new locality yielding giant Guadalupian (Lower Permian) fusulinids in east-central Alaska extends the range of these forms much farther north than previously known, and into a tectonostratigraphic terrane from which they previously had not been reported. The number of areas from which giant parafusulinids are known in North America is thus raised to eight. Three of these localities are in rocks that previously had been referred to the allochthonous McCloud belt arc, and one, West Texas, is known to have been part of Paleozoic North America. Comparison of species from all areas suggests that there are two closely related species groups: one represented in Texas and Coahuila, and the other represented in Sonora, northern California, northeastern Washington, southern and northern British Columbia, Alaska, and apparently in Texas. These groups may differ because they are of slightly different ages or because interchange between the faunas of Texas–Coahuila area and the other regions was somewhat inhibited during the Early Permian.

Kaempferia noctiflora, another precocious flowering species of Kaempferia subgen. Protanthium (Zingiberaceae) from Northern Thailand is described and illustrated. Pure white flowers with nocturnal anthesis and a tinged purplish red patch along the midvein of the upper surface of the leaves are the unique characters of this new taxon. The morphological characters of K. noctiflora are compared to closely related species and a key to Thai precocious flowering Kaempferia species is also provided.

Heteropanope glabraStimpson, 1858 belonging to family Pilumnidae is reported for the first time from the mangrove mudflats of India. The identification of the species is difficult because the species shares similar morphological characters with other closely related species likeBenthopanope indica(De Man, 1887). Studies in the past have reported the presence ofH. glabrafrom coastal areas of Burma to Japan. The present study reports the presence ofH. glabraon the western coast of India, which lies outside the old distribution range of the species.

Alpinalona gen. nov. is described for two species found in high altitude localities of continental North America and South America: Alona manueli (Sinev & Zawisza, 2013) from the Neovolcanic Mexican Axis and Alpinalona cajasi gen. et sp. nov from El Cajas National Park (Ecuador). The new genus is separated from Hexalona and allies by the absence of limb VI and filter plate V;  from Anthalona, Coronatella and the elegans-group by having seven setae on exopodite III, and by the presence of a well-developed seta 1 on the IDL of limb III; from Alona s. str. (quadrangularis-group) and Ovalona, by two main head pores, lateral head pores located close to main pores, and by a bilobed exopodite V; from Ovalona by the presence of seta (i) and inner setae 2–3 on limb I, and setae 4–5 of exopodite III being of same size; and from Alona s. lato by weakly developed marginal denticles of postabdomen, clusters of thin setulae on ventral surface of limb I, and by plumose setae 5–6 of exopodite IV. Alpinalona cajasi sp. nov. can be easily distinguished from A. manueli by the following characteristics: prominent posterodorsal angle of carapace; broader headshield; longer PP distance; and postanal marginal denticles organized into groups.
