Eriogallococcus Hodgson & Magalhães 2011  

Eriogallococcus Hodgson & Magalhães in Hodgson et al. 2011   , 56. Type species: Eriogallococcus isaias Hodgson & Magalhães   by monotypy and original designation.

I ntroduction. This monotypic genus from Brazil induces tall conical galls on the leaflets of Pseudobombax grandiflorum   ( Malvaceae   ). The adult male was described in Hodgson et al. (2011), along with a summary of its biology.

Generic diagnosis based on adult male morphology of E. isaias   ( Fig. 33 View FIGURE 33 ). Body not attenuated and abdomen more or less parallel sided but with a long penial sheath; body setae quite short, with hs and fs almost indistinguishable. Head: quite setose; simple pores absent; head with a few light striations or ridges; dorsal mid-cranial ridge absent; preocular ridge well developed; antennae 5 segmented; flagellar segments with hs and fs, these almost indistinguishable and all long; capitate setae present on apical antennal segment only. Thorax: prescutum with prescutal setae; scutal setae present laterally; scutellum with 0 or 1 scutellar setae; postmesospiracular setae abundant, mainly fs; basisternum with abundant setae; metasternal setae common; postmetaspiracular setae present; tegular setae mostly absent; tarsi 1 segmented; tarsal digitules setose; claw digitules dissimilar but capitate; claws with a denticle. Abdomen: fs almost indistinguishable from hs; glandular pouches present on segment VIII; glandular pouch setae quite short; penial sheath long, about 1/4th total body length, narrowing abruptly, with three quarters of length very narrow; segment IX without setae; with 2 pairs of long setae near apex of style.

Comment. The adult males of E. isaias   are immediately seperable from other males in this group in having: (i) 5-segmented antennae; (ii) an extremely long, fine penial sheath, and (iii) no or few tegular setae. The adult male of E. isaias   is superficially similar to that of Capulinia sallei   but the latter has 10-segmented antennae and 2-segmented tarsi.
