Organization and physiology of the insect dorsal ocellar system.
Face silver pruinose, frons and vertex red-gold pruinose, mystax black, ocellar macrosetae black.
Body largely glabrous, sparsely covered with minute, appressed, simple yellowish hairs except long, stout, erect hairs as follows: distal margin of labrum and inferior margin of mandible (longest at least twice median ocellar diameter) ; vertex and preoccipital border with few sparse hairs (at most half width of median ocellar diameter); anterior and lateral margins (next to axilla) of mesoscutum (1-2 times median ocellar diameter) (Figs.
3, 4); pale ocellar areas obvious, about half as long as coxae II; surface without scale-like setae but with numerous tubercles densely covering most of surface; with only slight depressions: one along midline, one on each side running from midline to rear of coxae II.
These ocellar aggregations typically have fewer than a dozen facets.
Face, frons and vertex dull red-gold pruinose, mystax black, ocellar macrosetae black.
Female: ocellar triangle long and sharpened with a rounded apex reaching the lunule (Fig.
Head blackish brown with grayish microtomentum; orbital plates subglossy blackish brown with microtomentum; ocellar triangle darkish brown without microtomentum; lunule strap-shaped, darkish gray with black margin.
Ocellar tubercle large, raised and blackish velvety (Figs.
altamirae but clearly differs from that species by the small size, narrower ocellar triangle (distance between posterior ocellus comparated with distance between posterior ocellus and eye), longer malar space; anterior part of mesopleuron more evenly punctate (not present only centrally), subalar prominence forming a sharp flange; mesosoma yellow with black marks on the mesoscutum (not longitudinal black vittae), propodeum brownish yellow, legs yellow and metasoma reddish brown.
Moreover, Asilidodexia was alternatively considered as member of the tribe Notochaetini (Lopes, 1969) and Johnsoniini (Verves, 1989), and closely related to Harpagopyga Aldrich, based on aedeagal morphology, reduced ocellar setae, and head shape (Lopes, 1938, 1992).
Upper frons, ocellar area, and vertex with coarse, dense punctures, vertex with dense, conspicuous transverse ridges; in male, antennal joints 3-12 beneath with narrow carinae (Fig.
