DEFINITIONS

ARREMONOPS
(Passerellidae; Ϯ Olive Sparrow A. rufivirgatus) Genus Arremon Vieillot, 1816, sparrow; Gr. ωψ ōps, ωπος ōpos  appearance; “(71.)  GENUS ARREMONOPS RIDGWAY.  ...  586. A. rufivirgata LAWR. Texas Sparrow.   ...   (71.)  Page 434, GENUS ARREMONOPS.  New genus: Type, Embernagra rufivirgata LAWR.  The Mexican and Central American species usually referred to the genus Embernagra LESS. are so different in structural and other characters from the type of the latter (Emberiza platensis GMEL.) that only a moment's comparison is necessary to demonstrate their generic distinctness.  The name chosen for the new genus is selected on account of the very close affinity of the birds in question to those of the genus Arremon VIEILL. (usually placed among the Tanagers).  In fact, I have found it difficult to discover reasons for separating them generically from the latter.” (Ridgway 1896); "Arremonops Ridgway, Man. N. Amer. Bds., 2nd ed., pp. 434, 605, 1896—type, by orig. desig., Embernagra rufivirgata Lawrence." (Hellmayr, 1938, Cat. Birds Americas, Pt. XI, p. 439).
