Echinicerya anomala Morrison

Echinicerya anomala Morrison, 1930: 18 .

Unmounted material. Adult female living exposed on host during growing period. Female covered with white secretion and with one median incomplete row of conspicuous, elongate, truncate-conical tufts dorsally; one complete marginal row of short truncate-conical tufts, and an almost complete intermediate row of similar tufts on each side; colour of denuded body in life coral-red, but varying in shade. Largest dimensions when covered with white secretion 9 mm long, 5 mm wide and 5 mm high. Eggs deposited beneath body of female that becomes concave as oviposition progresses (adapted from Morrison, 1930).

Slide-mounted material. Adult female elliptical, 5.5–8.4 mm long, 4.3–6.4 mm wide. Antennae 11 segmented. Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for tribe, derm at atrial opening with cluster of 20–25 multilocular pores, each with bilocular to trilocular centre and 4–8 outer loculi. Spiniform setae covering dorsal surface, forming marginal clusters and medial longitudinal row on abdomen; absent from medial clusters of pores on head and thorax; scattered over entire surface of ventral head, thorax and margins of abdomen. Hair-like setae scattered amongst spiniform setae on dorsal surface and ventral surface, longest around margins and scant in transverse rows on ventromedial to submedial abdomen. Flagellate setae distributed as for tribe. Simple multilocular pores, each 10–14 µm in diameter, with bilocular, trilocular or quadrilocular centre and 6–10 outer loculi, forming medial clusters on dorsal head and thorax, submedial clusters on each side of head and also present surrounding small, sclerotized patches of derm arranged in transverse rows on abdomen and scattered amongst setae on marginal to submarginal ventral head, meso- and metathorax, and in marginal clusters on all body segments. Simple multilocular pores, each 10–12 µm in diameter, with bilocular centre and 4 or 5 outer loculi, scattered on ventromedial head and prothorax. Simple multilocular pores, similar to vulvar pores, each 13–15 µm in diameter, with bilocular centre and 5–10 outer loculi, forming transverse rows on ventromedial to submedial abdomen. Ovisac band absent. Marsupium absent. Vulvar opening surrounded by short spiniform setae and typical multilocular pores each 14–16 µm in diameter with bilocular to trilocular centre and 8–12 outer loculi. Cicatrices each circular to slightly elliptical, 20–40 arranged in 2 lateral longitudinal rows on each side of abdomen, smaller cicatrices make up inner longitudinal row. Abdominal spiracles in 3 pairs on abdominal segments VI–VIII; multilocular pores absent from derm at each spiracular opening. Anal opening and anal ring as for tribe, except derm surrounding anal opening sclerotized; anal opening surrounded by spiniform setae and typical multilocular pores, each 13–14 µm in diameter, with bilocular to trilocular centre and 10–12 outer loculi.

First-instar nymph as for tribe except in the following features: abdominal spiracles in 3 pairs, anal tube with ring of 9 pores, each side of dorsal metathorax and each dorsal abdominal segment with a submedial row of 3–5 multilocular pores, and 5 pairs of long hair-like setae at abdominal apex.

Type data. GUATEMALA: Quirigua, ex Acacia , 16.iii.1928 (F. Schrader); ex Acacia sp. , Spring 1929 (S. Hughes-Schrader).
