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)
.

Cockerell. Macropterous
male. (
Eriococcidae, Gondwanan
group). Where C=fleshy seta, D=hair-like seta and K=tibia and tarsus of metathoracic leg. For abbreviations, see p. 8.

Hodgson, Mille & Cazères. Macropterous
male. (
Eriococcidae, Gondwanan
group). Where A=hair-like setae, B=fleshy seta, C=proximal end of metathoracic leg, D=dorsal view of penial sheath, E=ventral view of penial sheath, and F=ventral view of anterior end of head.
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.
