Oligopogon species tend to be heavily pruinose
and the extent and distribution of apruinose areas provide useful characters in separating species.
Abdominal sterna II, III and lateral parts of IV heavily punctured, the others without punctation, covered with short, appressed macrotrichia, some parts pruinose
2 cm wide (often nearly as wide as long), broadly ovate or elliptic, the lower ones acuminate, the upper ones acute, inflated, spreading and exposing the sepals, membranaceous, nerved, the adaxial ones glabrous, the abaxial ones coraline, densely and finely pruinose

The blue-gray, pruinose
apothecia and green leprose thallus are good diagnostic features of this lichen.

but is more obligately restricted to calcareous substrates, has a densely white pruinose
upper cortex, and lacks zeorin.
5-4 cm broad; reddish- to olive-brown; surface dry and pruinose
when young, becoming moist and smooth with age; margin: striate, upturned and often ragged.
Mesonotum: Extensively pruinose
with following apruinose areas: postpronotal lobes, large lateral area anterior to transverse suture, extensive area postsuture that extends to much of postalar lobe, pair broad medial stripes extending almost to anterior margin, but falling far short of posterior margin.
DIAGNOSIS: Recognized by the shiny black basic coloration, brown antennal segment I and basal 1/5 of II, dense, silvery, reclining setae on anterior part of the totally blackened scutellum, anteriorly flattened and pruinose
procoxa, well developed metafemur, widened posterior wall of bursae, and narrowed sclerotized rings.
catharinae that, when the scales fall off, leave exposed in certain places the pruinose
layer which is deposited beneath them.
