Countries: 1

Systematics: In the second-instar female, this species is commonly characterized with A echinata in having a perforated flap on the curved brim of the ventral surface of the pygidium, but it is easily distintuishable from the latter in having no spinous processes in the prepygidial region and in having aristate marginal sclerites on the dorsal disc of the pygidium. In the second-instar male, this species is recognizable in having a group of many microducts on the margin just anteriorly to the level of the anterior spiracle. (Takagi, 2008)
Structure: Adult female pygidium protruding from an exuvial cast of the second-instar shows a total of 9 marginal ducts and no trace of an undulate or reticulate linear pattern. Second-instar female prepygidial region plain, not areolate, nor echinate; with about 30 ducts scattered submarginally on each side. Dorsal disc tending to be reticulate extensively; margin with a continuous row of about 38 sclerites, which are oblong and apically aristate except for ones occurring towards the base of the pygidium. Second=instar male pygidium apically with a pair of rather prominent, sclerotized, dentate processes, which may be interpreted as median trullae; another less prominent pair mayh represent the second trullae.
