Female ( ICAR / NBAIR / P4444 ), INDIA : Odisha : Bhubaneswar , Odisha University of Agriculture and Technology ( OUAT ), 20.264°N 85.813°E , 45 m , YPT, 31 January 2016 . Paratype . 1 male ( ICAR / NBAIR / P4445 ) Odisha : Bhubaneswar , OUAT , 20.264°N 85.813°E , 45 m , YPT, 31 January 2016 . Etymology The species epithet ‘parviocula’, meaning ‘small eyed’ in Latin, refers to the size of the eyes in this species. The name is treated as an adjective. Diagnosis This is the only species of the genus that has small eyes, brachypterous wings and T3 with dense setigerous punctae.
