Orafortis Hardy : in Kondo, Hardy, Cook and Gullan, 2006: 29–30 .

Type species: Orafortis luma Hardy , in Kondo, Hardy, Cook and Gullan, 2006: 30–33.

Generic diagnosis. Adult female ( Fig. 30 ). In life, covered by spiky test, cryptic on hairy stems or stem axils. Adult female with sclerotised anal lobes, protruding posteriorly; suranal seta slightly enlarged. Dorsum. Derm nodulose, sclerotised posteriorly. Setae spinose, of 1 size except posteriorly where smallest. Macrotubular ducts of 2 sizes: smaller size with sclerotised rim; larger size without rim. Microtubular ducts with longitudinal division, often associated with base of spinose setae. Loculate pores absent. Margin. Undefined. Venter. Setae hairlike medially, spinose laterally, smaller than dorsal setae except on head where about same size. Macrotubular ducts of small size only, most abundant posteriorly. Microtubular ducts absent. Loculate pores primarily quinquelocular. Cruciform pores absent. Antennae 6 segmented. Frontal lobes and antennal tubercles absent. Labium 3 segmented; basal segment with 1 pair of setae. Metathoracic legs with translucent pores on coxa. Claw digitules similar; claw with denticle. Vulva present between VII and VIII.

Known only from Myrtaceae .

Comments. Orafortis is a monotypic genus known only from Chile. For a detailed description of the adult female, see Kondo et al. (2006), who considered that O. luma was superficially like Eriococcus Targioni Tozzetti (all species currently in the genus Eriococcus from South America are here considered to belong to other genera (See Appendix 1)) but can be distinguished from all those known from Chile in having: (i) distinct sclerotic rims around dermal orifices of macrotubular ducts; (ii) sclerotic nodules on dorsal surface of posterior abdominal segments; (iii) microtubular ducts opening at bases of enlarged dorsal spinose setae; and (iv) 2 sizes of dorsal macrotubular ducts. Kondo et al. discuss the differences between O. luma and other Eriococcus (Acanthococcus) species from Myrtaceae from Chile. Kondo et al. (2006) also make some comments on the structure of the first-instar nymph of O. luma but do not describe it in detail.
