Diagnosis
ReferenceDiagnosis
B. Schaeffer and N. G. McDonald 1978Dictyopyge differs from Redfieldius and other genera in the family Redfieldiidae in having the snout region either weakly ossified or unossified but covered with minute, closely spaced, blunt, bony tubercles; frontals relatively large, length nearly twice greatest width; single ovoid suborbital; no dermohyal; dermal skull bones ornamented with flattened, somewhat imbricating tubercles or ridges; anal fin (when completely preserved) lobate rather than triangular, with broad, segmented fin rays.
