Remarks

• Systematics: The main character-states diagnosing the adult female of A. schimae are: (i) anteroventral sclerotizations absent; (ii) anal lobes showing weak sclerotization throughout but with strong sclerotization on inner margins; (iii) four spinose setae present on inner margin of each anal lobe; (iv) multilocular disc-pores absent from ventral surface of anal lobes (Borchsenius’ figure suggests they might be present); (v) multilocular disc-pores present on abdominal segments II–VIII and on metathorax, with a complete band on segment VII; (vi) dorsum with two types of tubular ducts, a narrow duct sparsely on head and thorax and broader ducts present on dorsum of posterior abdominal segments; (vii) tubular ducts very sparse or even absent medially on venter; (viii) cribriform plates absent, (ix) leg stubs present, each with one or two small setae at base, and (x) transverse bands of dorsal 8-shaped pores present on abdominal segments III/IV and VII. The adult female of A. schimae would appear to be most similar to those of A. atratus and A. muratae.
• Structure: Adult female pear shaped. Cover of female strongly convex, often irregularly conical, dirty brown with narrow whitish bands. Cocoon of male nymph elongate oval, yellowish white, with a distinct longitudinal keel and many transverse grooves, surface with tiny projecting threads. First stage larva elongate oval and narrowed to the posterior end (Borchsenius, 1960d).
• Biology: This species was observed in masses on host (Borchsenius, 1960d).
• General Remarks: Detailed description and illustration by Borchsenius (1960d).
