Stictococcus intermedius

Adult female body on microscope slide broadly oval to rotund, 2.08–2.60 mm long, 1.80–2.40 mm wide, membranous at first, mature specimens heavily sclerotized. Dermal pores abundant, comprising large bilocular oval pores about 8 µm long, 5 µm wide and trilocular pores about 9 µm wide. Dorsal surface with a series of marginal barbed setae 75–160 µm long, pointed or bifurcate or trifurcate, longest posterior marginal setae on apparent anal lobe area about 256 µm long. Long submedial flagellate setae present, some on head about 432 µm long, others 270–360 µm long. Medial flagellate setae surrounding anus about 378 µm long. Minute slender flagellate setae 15–22 µm long. Submarginal setae shorter, barbed, spatulate distally, each 37–51 µm long. Ventral surface with small quinquelocular pores about 4 µm in diameter, almost encircling vulva then curving posteriorly to midline in a double to triple row extending to apex of abdomen. Marginal flat setae 30–36 μm long, each expanding distally to a lobulate apex mostly about 30–39 µm wide, with 3–7 distal lobules. Other ventral setae short, almost spine-like, 15–27 µm long. Long flagellate setae about 205 µm long present around margins and medially. Legs well developed, hind trochanter + femur 165–195 µm long, hind tibia + tarsus 162–193 µm long. Ratio of lengths of hind tibia + tarsus to trochanter + femur 0.96–1.05. Adult male total body length 1.37–1.45 mm. Antennae short, 7 segmented, less than one-third total body length. Wings hyaline, about 850 μm long, 350 μm wide. Aedeagus 285–290 μm long, 31–34 μm wide at base, gradually narrowing to a fine apex.
