| Abstract: | Abstract Parobia husbandi gen. n., sp. n. is described from material collected from the subelytra of the southern eucalyptus leaf beetle, Chrysophtharta agricola (Chapuis), in Tasmania, Australia. Parobia gen. n. is distinguished from other podapolipid genera adult males and females with four pairs of legs and no setae on genua I?IV and femora III?IV, adult females with setae v1 and sc2 < 20 µm, and at least two pairs of coxal setae peg-like, adult males with dorso-terminal genitalia, dorsal shields C-D-E fused, and physogastric larval females with plates C and D entire. A series of morphological plesiomorphies and biological apomorphies link Parobia gen. n. with Chrysomelobia Regenfuss, the most basal genus of Podapolipidae. |
