Marine Mollusc Diversity along the Southwest Coast of Sri Lanka
C.H.T. Rubesinghe & S.R. Krishnarajah
*Corresponding author. E-mail: dentallium@gmail.com
Molluscan species as well as class-level diversity is highest in the marine environment. The current survey data reveals that Sri Lanka is inhabited by about 240 species of marine molluscs belonging to four of the seven classes representing marine molluscs. The study area, along the southwest coast of Sri Lanka, experiences the southwest monsoon from May to September, which has a significant impact on climate and oceanographic conditions in this region.

A pentastome (Armillifer moniliformis) parasitizing a common rat-snake
T.S.P. Fernando* & V.A.K. Fernando
*Corresponding author. E-mail: saminda@ou.ac.lk
Pentastomes are a group of relatively poorly known parasites that are neglected both in veterinary parasitology text books and curriculum. The pentastomes are currently classified in a separate phylum, Pentastomida, because they exhibit characteristics of both the phylum Arthropoda and Annelid. This group comprises of approximately 100 species of vermiform arthropods that are all obligate parasites of the lower and less often upper respiratory tract of vertebrates. Adult pentastomes are segmented and worm like, measuring 0.5 to 20 cm in length. However they are easily distinguished from any other parasite because they bear 2 pairs of retractile hooks on either side of the mouth. They also have a distinct tongue shaped appearance; hence they are called linguatulids or tongue worms.

Tachaea spongillicola (Cymothoida: Corallanidae) from West Bengal, India
M.K.D. Roy* & S. Mitra
*Corresponding author. E-mail: malay_7@rediffmail.com
The isopod Tachaea spongillicola (Corallanidae) was described by Stebbing (1907) from the freshwater sponge Eunapius carteri (formerly Spongilla carteri) at the Indian Museum Tank, Kolkata, India. Since then, this species did not appear in literature for nearly hundred years. In 2003, Mariappan et al. reported this isopod from three locations along the course of the Cauvery River near Tiruchirapalli, India. They found this species to occur on three species of prawns. However, during a recent survey at Burdwan (on 18 December 2012), the first author collected six specimens of this species (Registration Number ZSI C 6007/2) on the prawn Macrobrachium lamarrei from Damodar River at Kathgolaghat near Polempur (~2 km SE of Burdwan Town). The size of the isopod specimens varied between 7.6–8.0mm and 2.6–3.5mm. The specimens were found to fully match with the description of Stebbing (1907). Thus this endemic species is here recorded after 106 years from West Bengal.

STUDIES ON DIVERSITY, DISTRIBUTION, AND CONSERVATION OF THE BAT FAUNA IN MAHARASHTRA STATE, INDIA
Vishakha S. Korad
*Corresponding author. E-mail: vishakhakorad@yahoo.com
Abstract
Maharashtra state is the third largest by area in India. Maharashtra’s bat fauna comprises eight families, 23 genera, and 41 species, most of which are insectivorous microchiropterans. Eleven of the 41 bat species are found throughout the state whereas 21 species have few colonies with restricted distribution. Five species endemic to South Asia occur in the state. Maharashtra is separated into six divisions in this paper on the basis of geography, topography, and agro-climatic conditions; the presence of bat species and their roosting sites are reported per division. The IUCN status of bat species is listed, as well as endemism. Types of forests in the state and forest cover in each of the six divisions are considered for discussion in the context of bat distribution. Bat species richness and evenness are compared using the Shannon-Weaver (S-W) Index and Simpson’s indices (Reciprocal and Diversity). The results are discussed from the viewpoint of conservation of bat fauna in forest areas in general and the Western Ghats region of the state in particular.

Tall Tales of a Tropical Squirrel
Emily Mae Meijaard, Rona Anne Dennis & Erik Meijaard
*Corresponding author. E-mail: emily.meijaard@gmail.com
The Tufted Ground Squirrel, Rheithrosciurus macrotis is an endemic of the South East Asian island of Borneo. This species is remarkable in several aspects. Phylogenetic research indicates that its nearest living relatives are a group of South American squirrel species. It is unclear how the evolutionary lineage leading to Rheithrosciurus ended up on Borneo without leaving behind any known relatives on either the Asian or North American land masses. The lineage of ancestors of Rheithrosciurus occupying Eurasia is either extinct without known fossil remains or the genus supposedly colonized Borneo in an independent long-distance colonization event. More recent studies indicate that the Rheithrosciurus lineage diverged from a group of Palaearctic species of the genus Sciurus as early as 36 million years ago, and colonized Borneo overland from South East Asia.
