I took these photos long ago, now I am interested in identifying the species of this larva from these pictures. I collected these larvae specimens from seasonal valleys of Southwest Saudi Arabia, and tested their efficacy of mosquito larvae predation in the lab. I need someone, if possible, to confirm or suggest to me a certain species as they appear in the pictures. I`m sure the appearance of the larvae in the pictures is not quite clear, nevertheless, I would appreciate any effort. According to me, as I searched in the literature, I propose that they could belong to the genus Sternolophus and the species could be decens.
Please, see the attached file ( Morphological characteristic of Hydrophilini ................).
