AbstractA national survey shows that the merchant grain beetle, Oryzaephilus mercator Fauvel, has been present in Canada since at least 1925 and that it has become firmly established as a household pest of processed cereal products preferably of high oil content, but has not been reported from stored grain. A related species, the saw-toothed grain beetle, Oryzaephilus surinamensis (L.), infests both stored grain and processed cereal products. Illustrations are provided to show the morphological characters by which the two species may be recognized and separated.

Alive individual adult sawtoothed grain beetle Oryzaephilus surinamensis (Linnaeus, 1758) was discovered inside a nest mound of the red wood ant Formica rufa Linnaeus, 1758 during a survey of myrmecophilous invertebrates. The sawtoothed grain beetle is a widespread indoor pest that has not previously been found in an ant nest. It is one of the most common pests in stored grain and cereal products, but the natural life-style of the species is not known. As the site of discovery was exceptional, we verified the species identification using the DNA barcode. If the sawtoothed grain beetle can live in mounds of red wood ants, the mounds may become widespread source habitats for the future infestations of this serious stored product pest.

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.

A new butterfly species, Podanotum pulsar Prieto & Rodríguez n. sp. is described from the high Andes of Colombia. Wepresent a brief discussion on its systematic placement and on adult ecology. Adult specimens and the genitalia of the male andfemale are illustrated and compared with the most closely related species Podanotum glorissimum Bálint & Wojtusiak, according to morphological characters.

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.

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.

Allium xinlongense from western Sichuan Province, China, is described as a new species. Its diagnostic morphological characters were confirmed to be valid by comparing them to those of related species, such as A. maowenense, A. chrysanthum, A. rude, A. xichuanense, A. chrysocephalum, and A. herderianum. Molecular phylogenetic analysis (combining ITS and rpL32-trnL markers) indicated that this new species is a member of Allium sect. Daghestanica. A comprehensive description of this new species is provided, including habitat environment and detailed morphological traits.

AbstractThe new corticolous lichen fungus Platythecium seychellense is described from the Seychelles. Morphological characters as well as distribution and resemblance to related species are discussed. The species is characterized by a crustose, grey-green, smooth thallus lacking lichen substances, elongate and slender apothecia having flat, red-brown discs and grey 3-septate ascospores. A world key to all currently known species in the genus is presented.
