Entomology (Study of Bugs)/Identification of coleopterans
I wanted to know which genus of Order: Coleoptera, Family: Limnichidae are found in freshwater in Gujarat,India. I have found one of which I am attaching a picture also. It will of great if you can help me on this.
I am also attaching one picture of a hydrophilid. I would request if you can help me identify its genus.
Unfortunately there are not many identification keys to identify Limnichidae, rather most of the beetles, without the specimen in hand. I can only help you narrow down on Bryyhunis sp. which has several species found in India. You can refer to: http://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1196&context=insectamu
As for the Hydrophilidae, could you also check whether it is Noteridae or possibly Dytiscidae?
ZSI has a checklist of aquatic beetles, in case you would like to refer to it: http://zsi.gov.in/checklist/checkist%20of%20aquatic%20coleoptera.pdf
I hope this helps.
