Mouse deer is known as the smallest and one of the most primitive ruminants. The lesser and the greater mouse deer originated in three different parts of Malaysia were examined for cytogenetic study. The chromosome number of the mouse deer was 2n=32, consisted of 15 metacentric autosome pairs and X and Y sex chromosome pair. G-, R-band revealed polymorphisms of sex chromosomes among the mouse d...

The immature stages of Kuwanina betula Wu & Liu are described and illustrated. Based on morphological and molecular data (18S and 28S rDNA), it is argued that K. betula is closer to Pseudochermes Nitsche than to Kuwanina Cockerell in Fernald and so this species is transferred to Pseudochermes as P. betula (Wu & Liu) comb. nov..

Paractinolaimus sahandi n. sp., found in wet soil samples collected from the rhizosphere of grasses of Sahand Mountains, Iran, is described. This new species is characterized by its long body (3.5-4.7 mm), high a value (74.5-88.5), anterior location of posterior subventral nuclei, occupying 62.5-68.0% of glandularium distance, the presence of 1-4 pre- and 1-3 post-vulval papillae and numerous t...

The present study describes the anatomy and surface topography of the metacercaria of Microphallusprimas (Jägerskiöld, 1909) infecting the shore crab Carcinus maenas (L.) in Aveiro estuary, northern Portugal. The metacercaria species identification resulted from the combined use of morphological and molecular data, particularly the 28S rDNA gene. The metacercariae encysted preferentially in the...

The mitochondrial genome of basal animals is generally more slowly evolving than that of bilaterians. This difference in rate complicates the study of relationships among members of these lineages and the discovery of cryptic species or the testing of morphological species concepts within them. We explore the properties of mitochondrial and nuclear ribosomal genes in the cnidarian order Actinia...

Cheirosporium gen. nov. is characterised by the production of sporodochial conidiomata, semi-macronematous to macronematous conidiophores that possess several distinct sterile branches, and cheiroid, smooth-walled conidia with rhexolytic secession. The 28S rDNA and ITS rDNA operon of this taxon were amplified and sequenced. A BLAST search revealed low homology between Cheirosporium triseriale a...

We show for the first time that the ventral diverticulum of the mosquito gut (impermeable sugar storage organ) harbors microorganisms. The gut diverticulum from newly emerged and non-fed Aedes aegypti was dissected under aseptic conditions, homogenized and plated on BHI medium. Microbial isolates were identified by sequencing of 16S rDNA for bacteria and 28S rDNA for yeast. A direct DNA extract...

Abstract A small slug found in the tropical greenhouse of Science Museum (MUSE) Trento (Italy) turned out to be a species little-known systellommatophoran family Rathouisiidae. We undertook detailed comparative anatomical and molecular studies using specimens MUSE slug, Rathouisia sinensis, sequences other deposited GenBank conduct systematic phylogenetic assessment. Analysis genitalia R. sinen...

Application of the FISH technique with the human 28S rDNA probe on metaphase spreads of the Chinese raccoon dog confirmed the presence of the NOR sequences on three A autosome pairs and the Y chromosome. Moreover, NOR-like sequences were found on the B chromosomes in the telomeric region of the long arm and in the proximal half of these chromosomes.

Two taxa, Hericium yumthangense (Russulales, Agaricomycotina) and Mycoleptodonoides sharmae (Polyporales, Agaricomycotina) are described as new to science from the Shingba Rhododendron sanctuary located in the northern district of Sikkim, India. Macro- and micromorphological characters are described and illustrated for both species, which are compared with allied taxa. ITS rDNA sequences suppor...
