Carpochloroides Cockerell 1899

Carpochloroides Cockerell 1899a , 12–13. Type species: Carpochloroides viridis Cockerell by monotypy.

Introduction. This is a small genus of two species restricted to South America. Little is known about them. Carpochloroides viridis Cockerell forms almost globular galls on the small twigs and petioles of its Myrtaceous host plants ( Ferris, 1957b). The adult female, first-instar nymph and adult male ( Fig. 29 ) were described in Hodgson and Miller (2010).

Generic diagnosis based on adult male morphology of C. viridis ( Fig. 29 ) Body not attenuated and abdomen more or less parallel sided with a short penial sheath; body setae long and mainly fs; hs and fs almost indistinguishable. Head: quite setose; simple pores absent; head with a few striations or ridges around each simple eye; dorsal mid-cranial ridge well defined; preocular ridge well developed; postoccipital ridge poorly developed; antennae 10 segmented; flagellar segments with hs and fs, both long and almost indistinguishable; capitate setae present on apical antennal segment only, each with 3 capitate setae. Thorax: prescutum without prescutal setae; scutal setae present medially; scutellum with scutellar setae; postemesospiracular setae present; metasternal setae frequent; metaprecoxal ridge poorly developed; postmetaspiracular setae present; leg setae all quite long; tarsi 1 segmented; claw digitules capitate; claws with a denticle. Abdomen: fs almost indistinguishable from hs; glandular pouches present on segment VIII; penial sheath with several pairs of long setae; penial sheath quite long, broad anteriorly, narrowing abruptly to a sharp apex.

Comment. The only other adult male eriococcid in the Gondwanan-group from South America that has glandular pouches and a short stout penial sheath is that of Stibococcus cerinus Miller & González but the male of C. viridis has 1-segmented tarsi whereas S. cerinus has 2-segmented tarsi.
