Remarks

• Systematics: Dromedaricoccus is a monotypic genus only known from Costa Rica. The adult female of D. hansoni can be immediately recognised by the general shape of the body and the circular, dome-shaped sclerotisation medially on the dorsum of the mesothorax. In addition, (i) the abdomen is drawn out into a narrow tube; (ii) the legs and antennae are much reduced; (iii) there are no anal lobes; (iv) the anal ring is a sclerotised area, perhaps with 2 small setae laterally; and (v) each spiracle has a C-shaped area of sclerotisation laterally around the spiracular opening. No other eriococcid genus has this combination of features in the adult female. The adult male of D. hansoni can be separated from the other known Neotropical eriococcid males in having the following combination of characters: (i) 6 segmented antennae, with fleshy setae much shorter than width of antennal segments; (ii) capitate setae on the antennae restricted to apical segment; (iii) antennal bristles apparently restricted to apical segment (or similar to fleshy setae on previous 2 segments); (iv) penial sheath short, only slightly longer than basal width; (v) fleshy setae not easily separable from hair-like setae; (v) legs relatively small; (vi) tarsal digitules unusually short; and (vii) head with many fleshy setae. (Hodgson, et al., 2011)
• Structure: Adult female head and thorax round and swollen. Derm mainly membranous but with a heavily sclerotised boss or hump mediodorsally approximately on metathorax, flattish on some (younger?) specimens and highly convex on others. Adult male antennae short, about 1/4th total body length; body setose, particularly on head and venter; fleshy setae often curved, not always easy to separate from fine hair-like setae. Loculate pores entirely absent. Wings without either alar setae or sensilla. Hamulohalteres absent. Tarsi 1 segmented; tarsal digitules setose. Glandular pouches and glandular pouch setae present.(Hodgson, et al., 2011)
