Two non-native cichlid fish species from the natural waters of Chennai, India
G. Aravind* & J.D.M. Knight *Corresponding author. E-mail: aravind_manoj@yahoo.com
Non-native fish are introduced throughout the world mainly for improving fisheries, sport, ornamental fish trade and bio-control of mosquitos. The aquarium trade has not come under the scanner of environmentalists, conservationists, ecologists, and policy makers as much as trade in terrestrial endangered species. The avenues from captivity to the wild include the dumping of unwanted fishes, escape from tanks and breeding farms perhaps during storms, and unchecked drainage of water containing organisms from tanks, and public aquaria. Such organisms are usually healthy adults, which have a greater probability of surviving and reproducing in the wild. Introduced aquarium fish represent a major source of ecological destruction that may be locally alarming if ignored.

First reports of some Megachilid bees (Hymenoptera) from Kerala, India
A.S. Prakash & C. Bijoy* *Corresponding author. E-mail: anjusara2025@gmail.com
Family Megachilidae consists of long tongued bees which are easily recognized by the presence of two submarginal cells in the forewing (except in Fideliini) and the female bees from this family (except parasitic forms and Pararhophitini) can be distinguished by the presence of scopa underneath the abdomen. Genus Megachile Latreille, 1802 is one of the most diverse bee genera and they play a significant role in pollination. This genus consists of leafcutter bees, mason bees and resin bees

First report of lance lacewing, Spilosmylus tuberculatus from the Western Ghats
T.B. Suryanarayanan* & C. Bijoy *Corresponding author. E-mail: suryantb1995@gmail.com
In India, 16 species of lance lacewings (Order Neuroptera: Family Osmylidae) belonging to 8 genera and 3 subfamilies have been reported, but there has not been a single species reported from the Western Ghats region. Spilosmylus Kolbe 1897 is the dominant genus of the Subfamily Spilosmylinae and only four species: S. darjeelingensis Ghosh, 2000, S. lineatocollis (McLachlan, 1870), S. pretiosus (Banks, 1931), and S. tuberculatus (Walker, 1853) have been reported from India. Spilosmylus tuberculatus is a widespread species in eastern and southern Asia, but the species has not been reported so far from the Western Ghats region of India. Spilosmylus tuberculatus has been formerly reported from Balaghat (Madhya Pradesh), Assam, Andaman Islands and Maharashtra. Here we report it as the first record of the family Osmylidae from the Western Ghats.

Rediscovery of Anisogomphus ceylonicus (Odonata: Gomphidae) based on its larva
A.P. Sumanapala*, T. Ranasinghe & D. Sumanapala *Corresponding author. E-mail: apsumanapala@gmail.com
Anisogomphus ceylonicus (Hagen in Selys, 1878) is one of the rarest of the Sri Lankan Odonata. It was first discovered from Ramboda over 140 years ago based on a female specimen, which was originally described as Gomphus ceylonicus and later assigned to the genus Heliogomphus by F. C. Fraser. Almost a century later, Lieftinck (1971) collected an immature male and its exuvia of a clubtail dragonfly from Rambukpath Oya, 10 miles northwest of Hatton in 1962 and described as Anisogomphus solitaris. However, Bedjanič & van der Poorten (2013) recognized that H. ceylonicus is conspecific with A. solitaris, and thus reassigned it to the genus Anisogomphus. Since the discovery of the species, only these two records have ever been documented, despite odonatological surveys and numerous biodiversity explorations conducted on the island.

Spiders are efficient hunters that prey on a variety of invertebrates and vertebrates. They rely on strategies varying from the use of toughened silk to venom. The genus Hersilia Audouin 1826 is called two-tailed spiders due to its characteristic long spinnerets. It is distributed across the Afrotropical, Oriental and Australasian realms. Currently there are five species known to occur in India: Hersilia savignyi Lucas 1836, H. sumatrana Thorell 1890, H. tibialis Baehr & Baehr 1993, H. orvakalensis Javed, Foord & Tampal 2010, and H. longivulva Sen, Saha & Raychaudhuri 2010.
