Two new species of black flies, Simulium (Gomphostilbia) peteri sp. nov. and S. (G.) takaokai sp. nov., are described on the basis of reared adult, pupal and larval specimens collected from Peninsular India. These two new species are placed in the batoense species group within the subgenus Gomphostilbia. S. (G.) peteri sp. nov. is distinguished in the female by having a medium-sized round opening of the sensory vesicle and a large basal tooth on the claw, in the male by 12 vertical columns in the upper eye large facets, in the pupa by a ventral pair of 2 gill filaments somewhat thicker than the other filaments and in the larva by 5 hypostomal bristles per side lying parallel to the lateral margin. S. (G.) takaokai sp. nov. is characterized in the pupa by having the eight gill filaments with a medium-long common basal stalk and in the larva by the labral fan with 38 main rays and 4 hypostomal bristles on each side. Keys to 13 black fly species reported from Peninsular India are provided for females, males and pupae.

This paper aims to resolve the dual composition of the triakid shark-hosted tetraphyllidean genus Calliobothrium--an issue that has been recognized for over a decade. As it stands, this genus includes a number of large species with laciniate proglottids, most of which bear 3 suckers at the anterior margin of each bothridium, but it also includes a number of species that lack proglottid laciniations and bear only a single sucker per bothridium, most of which are relatively small. Discovery of 2 new species, 1 of each form, parasitizing the whitespot smoothhound shark, Mustelus palumbes, off South Africa, prompted the first molecular analysis of the genus. Bayesian inference and maximum likelihood analyses of 28S rDNA (D1-D3) sequence data generated for specimens of both new species as well as of 2 known species of the laciniate form (Calliobothrium australis and Calliobothrium cf. verticillatum) and 3 known species of the non-laciniate form (Calliobothrium violae, Calliobothrium riseri, and Calliobothrium barbarae) confirmed the reciprocal monophyly of the 2 clades, supporting establishment of a new genus. Because the type of Calliobothrium, C. verticillatum, is of the laciniate form, Symcallio n. gen., with Symcallio peteri n. gen., n. sp., from M. palumbes described as its type, is established to house members of the non-laciniate clade. The 11 described species consistent with this form are transferred to the new genus. A new species of the laciniate clade, Calliobothrium euzeti n. sp., is described from M. palumbes, and a revised diagnosis of Calliobothrium is presented. PMID:25506725

In Memoriam Dr. habil. phys. Inta Muzikante (08.01.1951-15.02.2012) Inta Muzikante Inta was born in Valmiera, a town in the northern part of Latvia. She attended school in Sigulda and high school in Riga. While at the high-school, Inta decided to study natural sciences. After graduating from high-school in 1969 she entered the physics section of the Physics and Mathematics department of University of Latvia and obtained her university degree in 1974. In parallel with University studies, Inta started to work at the Semiconductor Physics Research Lab at the University of Latvia. After graduating she was offered a position at the Physical Energetics institute of the Latvian Academy of Sciences, in the laboratory of Professor Edgars Silinsh, one of the most internationally well known Latvian physicists. Inta started researching electronic and photoelectric processes in organic crystals and thin films. This was a novel field, pioneered both internationally and in Latvia by Profesors E Silinsh, O Neilands and J Freimanis. It could be said that Inta stood at the cradle of this research field and stayed faithful to it all of her life. Her work was very successful and within a few years she advanced from research assistant to researcher and then leading research scientist. Her first scientific topic was studies of the mechanism of charge carrier photogeneration and separation in organic molecular crystals. In 1983 for a work
