Sajan; Vinayaka HegdeAleuroclava canangae (Corbett, 1935) was discovered on an ornamental Coleus species in Kerala, India, and represents the first occurrence of this species in India and on this plant host. The species is redescribed and illustrations of the puparium and adult males and females are provided along with morphometric data. A molecular analysis of the species using the COI gene was conducted to characterise it, determine its genetic lineage and compare it to seven other species of Aleuroclava Singh, 1931 and those of other whitefly genera. Results of the DNA analysis indicate that A. canangae forms a clade with Aleuroclava indica (Singh, 1932) which also has two pairs of very elongate, tuberculate setae which appear two-jointed because they have a wider basal part separated from a long slender apical part by a fine suture. The Aleuroclava canangae species group is established and an illustrated key is provided for the 12 species in the group, all of which were once placed in the genus Martiniella Jesudasan and David, 1990, now a synonym of Aleuroclava. The molecular analysis indicates that A. psidii (Singh, 1931), A. guyavae (Takahashi, 1932), A. montanus (Takahashi, 1939) and A. gordoniae (Takahashi, 1932) form a clade within the genus Aleuroclava and share similar morphological characters. Based on the results of the molecular and morphological analyses, Aleurothrixus trachoides (Back, 1912) is transferred back to Aleurotrachelus trachoides (Back, 1912) based on its morphology and the results of the DNA analysis.Item Evaluation of Goniozus nephantidis (Muesebeck) a larval parasitoid in the field against coconut black headed caterpillar (Opisina arenosella Walker) in Karnataka(2018) Chandrashekara, G.S; Maheswarappa, H.P.; Jilu V.
