A new species of Platybaetis viz., P. selvai sp. nov. is described herein based on larval collections from Tangon stream in the state Arunachal Pradesh Eastern region Indian Himalaya. It can be differentiated by following combination characters: (i) posterior margin abdominal segments IX with rounded 'U shaped spines; (ii) anterolateral gills IVII minute setae; (iii) claw 78 denticles; (iv) paracercus composed 1011 segments; (v) hindwing pads reduced, small. Brief ecological notes are appended.
Three new species of Leptophlebiidae viz., Choroterpes (Choroterpes) andamanensis Vasanth, Subramanian Selvakumar n. sp., Edmundsula meghamalaiensis sp. and Megaglena agasthiya are described based on our recent exploration mayflies from the streams Andaman Island, Tamil Nadu Kerala part southern Western Ghats. The genus Peters Edmunds, 1970 has extended distribution in peninsular India as represented by occurrence M. Larval key is provided to known subgenus along with map species.
We present the description of a new mayfly species, Platybaetis arunachalensis sp. nov., based on larval specimens collected from Arunachal Pradesh, India. Additionally, we provide first complete and record uenoi Müller-Liebenau, 1980, recently Nagaland, This study includes taxonomic updates for genus 1980 in India, along with distribution map species ecological insights into their habitats. Our work enhances understanding diversity contributing valuable information future conservation studies.
Two new species of the genus Thalerosphyrus are described based on larvae collected from India, viz., T. bengalensis Vasanth, Kubendran & Subramanian sp. nov. and sartorii nov., these Tamil Nadu West Bengal, India. The closely related to flowersi meghalayaensis compared all known Oriental region. These strongly distinguished flowersi, as demonstrated by clear photographs paratype specimen larva. A key India a distribution map provided.
A new species of Labiobaetis Novikova & Kluge, 1987, soldani sp. nov., is described from the larvae and reared male female imagoes Gadana River in southern Western Ghats India. Brief ecological notes are appended. The taxonomic status commented on light morphological traits associated imagoes.
As part of ongoing exploration the mayflies hill streams southern Western Ghats, we describe two new species: Nigrobaetis paramakalyani Kubendran & Balasubramanian n. sp. and Labiobaetis jacobusi The genus is reported for first time from India. Tenuibaetis frequentus (Müller-Liebenau Hubbard 1985) comb. was also collected in this area provide description species at imaginal stage. Brief ecological notes three are added.

ABSTRACT The efficacy of entomopathogenic fungi [Beavueria bassiana (Bb08, Bb10) and Isaria fumosorosea (Ifr)] isolated from different regions Southern Tamil Nadu, India was assessed against red cotton stainer, Dysdercus cingulatus. All the tested isolates showed 100% mortality. B. such as Bb08, Bb10 an I. exemplified significant mortality among tested. LC50, LC90 correlation coefficient were calculated for Ifr unveiled lowest LC50 (5.9 x 105 , 6.6 2.6 105) (1 109 7.3 108 3.9 108) value...

As part of ongoing exploration the mayflies in hill streams northeast India, Rhoenanthus (Potamanthindus) sapa Nguyen and Bae 2004 was reported as a new record based on larval collections from Meghalaya, India.
As part of continued efforts to explore the Ephemeroptera fauna streams or rivers Indian Himalaya, Heptagenia (H.) quadripunctata Kluge, 1989 is newly recorded based on fresh materials collected from North Western India. The redescription this species with morphological characters larvae freshly specimens and earlier descriptions appended. distribution map localities also provided.

The present study deals with diagnostic characters, diversity, distribution and status of seven species belonging to four genera Teloganodidae from southern India. Six them are endemic the Western Ghats as is genus Indoganodes Selvakumar, Sivaramakrishnan & Jacobus, 2014 one Eastern Ghats. Due this high percentage endemism, conservation habitats microhabitats harbouring ancient gondwanan lineage gains priority. A larval key known India also provided. pattern family confined Africa,...
