A catalogue of 107 species of liverworts (Marchantiophyta) and 8 species of hornworts (Anthocerotophyta), recorded from Assam, India is presented. This includes three new records for India viz., Cololejeunea denticulata (Horik.) S. Hatt., C. inflata Steph., Plagiochila furcifolia Mitt., and three species viz., Cololejeunea desciscens Steph. Colura ari (Steph.) Steph., Lopholejeunea eulopha (Taylor) Schiffn. new to mainland. Twelve species are new record for Eastern Himalayan bryo-geographical territory, 20 species as new to Assam and seven species are endemic to Indian regions.
A list of scale insects (Hemiptera: Coccoidea) intercepted on imported succulent plants at the plant quarantine of Korea from 2006 to 2010 is provided. A total of 15 species belonging to four families are listed. Of the 15 species that were intercepted, some species are potential pests that could gain entry and establish in Korea through the importation of plant material. Current information on intercepted scale insects is required to alert inspectors at quarantine sites to look carefully at succulent plants to prevent the introduction of an exotic species.
We conducted a morphological and mtDNA analysis of Cicindela decemnotata Say (Coleoptera: Carabidae: Cicindelinae) populations from throughout its geographic range to determine the extent of variation within the species and to assess the validity of subspecific names. The morphological study included an analysis of traditional subspecific characters including elytral color and maculations. These results provided evidence for the recognition of four subspecies of C. decemnotata, three of which are new: 1. C. d. decemnotata Say usually with green to dark green dorsal coloration and complete elytral maculations; it is widely distributed from Canada south to northern New Mexico and west into southern Utah and Idaho; 2. C. d. meriwetheri n. ssp. is distinguished by its bright green to green dorsal coloration, elytral maculation characterized by a thin middle band, a lack of humeral maculations, and a small number of genal setae; it has a restricted distribution from eastern Washington north to south central British Columbia; 3. C. d. bonnevillensis n. ssp. is distinguished by a combination of green to green-purple dorsal coloration and its greatly reduced elytral maculations; it is restricted to the area of ancient Lake Bonneville in north central Utah; 4. C. d. montevolans n. ssp. is distinguished by a predominately red-purple dorsal color and greatly reduced elytral maculations; its distribution is restricted to high elevations of the Bear River Mountains of northeastern Utah and southeastern Idaho. We also analyzed the mitochondrial haplotypes for cob and cox1 genes for one to six individuals from each of the six populations. This molecular analysis indicated recently diverged but discrete groups within C. decemnotata that are compatible with the subspecies distinctions postulated from morphology. These shallow molecular divergences within C. decemnotata are best explained by rapid phylogenetic radiation in the recent geological past in the wake of postglacial recession.
A new genus and species of armored scale insect (Hemiptera: Diaspididae), Protomorgania koebelei.
Dooley and Evans, is described and illustrated from specimens collected by Albert Koebele on Pittosporum sp.
(Pittosporaceae) in Australia around the year 1900. A key to the genera of armored scale insects similar to Protomorgania
and known to occur in Australia is provided.
Iranocichla hormuzensis occupies a biogeographically peculiar position. This endemic of southern Iran is the only Iranian cichlid. While it is phylogenetically related to African oreochromine members of the cichlid family, it remains unclear how it has dispersed into its current range. It is one of the many lasting enigmas of cichlid biogeography. Monogenean fish parasites may provide useful additional information in such cases. Therefore, I. hormuzensis was examined for these flatworms. A gyrodactylid parasite is reported and compared to congeners from the Palearctic and from cichlids. In this way, we verify whether it shows affinities to parasites from fishes that are either biogeographically or phylogenetically close to Iranocichla hormuzensis. The species is new to science and is described as Gyrodactylus jalalii sp. nov. This is the first description of a parasite infecting I. hormuzensis. Because of the fixation method or age of the material, DNA could not be isolated. Due to the lack of genetic data, no conclusions can be drawn on its phylogenetic positioning. Indeed, Gyrodactylus phylogeny cannot be inferred from morphological characteristics alone. Moreover, the congeners phenotypically reminiscent of the new species belong to a Gyrodactylus clade which is highly diverse in geographic range and host choice. Hence, there is no evidence linking the new species to an exclusively African or cichlid-bound Gyrodactylus lineage.
Hortipes gigapophysalis (Araneae, Corinnidae) is a new species described from both sexes from montane forest on Mt Nimba, eastern Guinea. The species is remarkable for its long, whip-shaped retrolateral tibial apophysis (RTA) on the male palp. The structure apparently has an insertable function as the epigyne of the female contains a separate set of ducts starting from a central concavity that is unique in the genus. This duct system is apparently meant to receive the supple RTA. This type of structural arrangement has never previously been found in spiders.
