15): Wide and oval, much wider than thorax, strongly convex ventrally, less convex dorsally; dorsum with a few setigerous tubercles at posterior parts of mediotergites and epipleurites (= dorsal laterotergites).
10); mesonotum broadly convex posteriorly, with 1+1 large tumescences bearing setigerous tubercles laterally; metanotum extremely short along midline.
4; integument with wart-like setigerous tubercles similar to those of adult but shorter.
1a Body with 16 setigerous of which 12 are uncinigerous; 7-10 pairs of opercular paleae: approximately 13-15 pairs of scaphal hooks; uncini with two rows of teeth....
1b Body with 17 setigerous of which 13 are uncinigerous; 8-13 pairs of opercular paleae; about 10 pairs of scaphal hooks; uncini with a single row of teeth....
A band of neurotrochal cilia runs along the ventral surface of the larva from just behind the mouth to the third setigerous segment (Fig.
For larvae of Armandia brevis, prototroch circumference and prototrochal cilium length increased with number of setigerous segments (Fig.
Visible abdominal sternites 2[degrees] to 4[degrees] slightly depressed at middle; 5th sternite widely convex, shiny, with scattered setiferous punctures; anal plate long, weakly concave, with a central, moderate prominence covered by setigerous
Members of the genus can usually be recognized by the following combination of character states: 2-segmented petiole; 2-segmented antennal club; propodeum lacking spines or angles; petiolar node well developed; head and body shining, sculpture restricted to setigerous
punctures and localized striae; clypeus longitudinally carinate, with a median, apical marginal seta.
