Phyllococcus cryptocaryae Percy, Watson & Hodgson , sp. n.

( Figs. 4D, E and F , 5 )

Material examined. Holotype adult female: Cryptocarya mannii / 5 July 2014 / USA, Central Waianae / Mountains , Oahu , Hawaiian / Islands, 21.4574N, - 158.0970W. / leaf gall / D. Percy leg. Hi 65.2-14 / mounted singly on a slide ( NHMUK) . Paratypes: data as for holotype; 3 adult females, mounted singly on slides (2 NHMUK, 1 BPBM); 1 pharate second-instar female nymph on 1 slide, and 2 third-instar female nymphs, one containing a pharate adult female, mounted together on 1 slide ( NHMUK) .

Note. The four adult female specimens are all slightly damaged, lacking some legs or antennae, and with the labium distorted. Due to the heavy sclerotisation of the dorsal shield, it is not possible to determine the extent of the sclerotisation of the posterior venter but it is here considered that the underside of the anal lobes may also be sclerotised to some extent.
