Spilococcus pacificus

Adult female body elongate oval, 2.7–3.3 mm long and 1.4–1.6 mm wide, soft and wingless, reddish orange in color, covered with white mealy wax. Antenna 360–450 µm long, with 8 segments and many flagellate setae; subapical segment with 1 fleshy seta, apical segment with 3 fleshy setae. Labium 165–186 µm long, usually same length as clypeolabral shield. Hind leg measurements: trochanter + femur 260–338 µm long; ratio of hind tibia + tarsus to trochanter + femur about 1:1.01–1.17; hind tibia with or without translucent pores on posterior surface; hind trochanter, femur and tarsus without translucent pores. Paired setose tarsal digitules present, subequal in length to minutely knobbed claw digitules. Anal ring 86–98 µm wide, bearing 6 setae, each 110–140 µm long. Cerarii: anal lobe cerarii (C18) each with 2 conical setae (12–21 µm long, 4–7 µm wide at base), 4–7 auxiliary setae and a concentration of trilocular pores; penultimate cerarii (C17) each with 2 conical setae, no auxiliary setae and some trilocular pores; anterior cerarii each with 2 conical setae and usually a few trilocular pores. Dorsum with a few oral rim tubular ducts on submarginal to medial areas of head, thorax and abdomen. Setae flagellate, 8–45 µm long, distributed segmentally; longer setae 18–136 µm long present on posterior abdominal segments. Oral collar tubular ducts of two sizes: large-type ducts (3–4 µm diameter) on marginal to submarginal areas of all abdominal segments and anterior thorax; small-type ducts present on head and thoracic segments, arranged in 1–3 rows on posterior abdominal segments VI–VII but randomly on VIII–IX. Anterior ostioles each with 16–29 trilocular pores and 3–5 setae; posterior ostioles each with 19–49 trilocular pores and 2–5 setae.
