Summary: | KEY TO ADULT MALE COCCOIDEA KNOWN FROM GREENLAND * (for an explanation of terms used, see the Figures) 1. Penial sheath at least 4 x longer than wide; scutum with a large quadrangular membranous area medially; ocular sclerites and genae covered in polygonal reticulations; loculate pores entirely absent (apart from in glandular pouches); body with frequent fleshy setae, even on abdomen; hamulohalteres absent. COCCIDAE (Pulvinaria glacialis Gertsson & Hodgson) (Fig. 9) Penial sheath never more than 2 x longer than broad; scutum without a large quadrangular area medially; polygonal reticulations absent from genae and restricted to around each simple eye on ocular sclerites; loculate pores usually present, at least on head but also generally on abdomen; body without fleshy setae on abdomen; hamulohalteres present. 2 2. Postoccipital ridge strong; scutum with two small membranous areas medially; scutellum with a welldeveloped scutellar ridge; claw digitules capitate and longer than claw; loculate pores absent apart from on head; apical antennal segment almost as wide as long; cranial apophysis well developed and trilobate; ostioles absent. ERIOCOCCIDAE (Figs 7 & 8). 8 Postoccipital ridge weak or absent; scutum without two small membranous areas medially; scutellum without a scutellar ridge; claw digitules setose and much shorter than claw; loculate pores often frequent and nearly always present in pleural region of abdomen; apical antennal segment at least twice as long as broad; cranial apophysis poorly developed or absent; ostioles present. PSEUDOCOCCIDAE (Figs 1–6). 3 3. Apterous; mesothorax mainly membranous; postoccipital ridge entirely absent . Chorizococcus multiporus Gertsson & Hodgson (Fig. 2) Macropterous; mesothorax heavily sclerotised; postoccipital ridge present. 4 4. With two pairs of glandular pouches, one pair on abdominal segment VII and the other on segment VIII; fleshy setae on antennae setose and at least twice as long as width of flagellar antennal segments . Peliococcus ... |
