- 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 balteatus (Green) (Fig. 3) With only one pair of glandular pouches, on abdominal segment VIII; fleshy setae on antennae thick, with a blunt apex, clearly different from hairlike setae and each about as long as width of flagellar antennal segments............................................................ 5 5. Several postmesospiracular setae present anterior to basisternum; fleshy setae clearly differentiated from hairlike setae on head; each gena with 4 + genal setae, some often fleshy; small convex pores on ventral epicranium of head.......................................... 6 Postmesospiracular setae very few or absent anterior to basisternum; fleshy setae not differentiated from hairlike setae on head; each gena with 3 or fewer genal setae, none fleshy; pores on head, when present, on dorsal epicranium.......................................... 7 6. Fleshy setae on head quite short; 3 rd, 4 th and 5 th antennal segments all equal to or shorter than 2 nd segment; postmesospiracular discpores and setae few immediately anterior to basisternum; fleshy setae of antennae short (17–20 μm on subapical segment), about width of antennal segments....................................................................... ........................................................... Trionymus bocheri Gertsson & Hodgson (Fig. 4) Fleshy setae on head almost as long as hairlike setae; 3 rd antennal segment longer than 2 nd segment and 3 rd and 4 th segments subequal in length; postmesospiracular discpores few or absent but setae quite abundant immediately anterior to basisternum; fleshy setae of antennae long (30 μm on subapical segment), longer than width of antennal segments ............................. Trionymus elymus Gertsson & Hodgson (Fig. 5) 7. With 0 or 1 loculate pore on dorsal surface of head; pleural region of each abdominal segment with 0 or 1 loculate pore; abdominal segment VIII with a pair of transverse sclerotisations mediolaterally on sternite; loculate pores absent from dorsal and ventral surfaces of abdomen; with several metatergal setae .................................................................................................... Atrococcus groenlandensis Gertsson & Hodgson (Fig. 1) With several loculate pores on dorsal surface of head; pleural region of each abdominal segment with 2–5 + loculate pores; abdominal segment VIII without a pair of transverse sclerotisations mediolaterally on sternite; loculate pores present on dorsal and ventral surfaces of abdomen; with only 1 pair of metatergal setae................................. ................................................................................. Trionymus thulensis Green (Fig. 6) 8. Length of fleshy setae on antennae equal to or less than width of flagellar segments of antennae; fleshy setae with a blunt apex; all pores on head quite small ................................................................................................. Eriococcus pseudinsignis Green (Fig. 8) Length of fleshy setae on antennae clearly greater than width of flagellar segments of antennae; fleshy setae with sharply rounded apices; some pores on head quite large ........................................................................... Eriococcus munroi (Boratynski) (Fig. 7)
