pseudohemihyalea is a genus of moths in the family erebidae described by régo barros in 1956. while the caterpillars of most species of "pseudohemihyalea" feed on broad-leaved trees (e.g. oaks, "quercus"), the "p. ambigua" group has larvae that feed on conifers. their forewing coloration has accordingly evolved to light-and-dark lengthwise striping, giving better camouflage among the slim needles of the host plants. in this, they seem to be convergent to certain geometer moths, such as "caripeta piniata" or "sabulodes niveostriata".
