Scea dimidiata (Walker) , new combination Figures 346A–C , 351 ; plate 33 [EX]

Thirmida dimidiata Walker, 1854: 466 .

TYPE LOCALITY: Colombia, Santa Fé de Bogotá.

TYPE: Syntype ³ ( BMNH).

DISCUSSION: Wing-pattern similarities suggest that S. dimidiata from central Colombia, and S. discinota (pl. 33) from western Venezuela, are sister species. Their FW and HW patterns, and most other morphological features, are the same. Means for separating S. dimidiata from S. discinota are provided in the Scea species key, as well as in the discussion for S. discinota (below).

DISTRIBUTION: Colombia (AMNH, BMNH, CMNH, CUIC, MCZ, MNHN, NMW, OUMNH, USNM, ZMH) .

DISSECTED: ³, Colombia, Cundinamarca, Subachoque, 2750 m, 28 Jan 1948, AMNH (genitalia slide no. JSM-629 ) ; ³, Colombia, Parish no . 31, 18 May 1915, CMNH (genitalia slide no.
