Distribution: Panama, Cuba, Dominica, Trinidad & Tobago, Venezuela. (Fig. 144).

Material examined: CUBA: ♂ at Phila., Pa, 4-VI-1934, Phila. 22701, Banana. MACN ; ♀ intercepted N. York, N. Y., 2-III-1933, Samance, Peltier, Woodbury, Banana flowerstalki. USNM ; DOMINICA: ♀ BWI, 2-VI-1936, Blackwelder C-36. USNM ; PANAMA: ♀ Barro C. Is., CZ, J. Zetek, 5176 V-1944, 45-4516, from fruit of Heliconia mariae (H.). USNM ; ♂ Canal Zone, Ho. 16473, 3-IX-1950, 12915, with Hevea (slide-mounted). MACN ; TRINIDAD: ♂ Brit. W. Indies, F. W. Urich, 1918-123, bred from Cocoa twigs. BMNH .

Discussion: This species is characterized by the homogeneous colour of hemelytra; it belongs to that group of species possessing a hammer-like left paramere, but in D. unicolor, this paramere is sinuous.
