Diagnosis. Libythea labdaca ancoata is most similar to L. l. labdaca but its forewing dorsum lacks a bright white streak in cell 1A + 2A, and its hindwing has a faint white median band which is strong and distinct in L. l. labdaca .

Type Specimens Examined. Libythea ancoata Grose-Smith 1891 , HOLOTYPE: ♂, Madagascar: Irast ( BMNH).

Other Specimens Examined. (14♂): MADAGASCAR: 4♂ ( BMNH) ; 2♂, Last ( BMNH) . 1♂, Antanosy ( BMNH) ; 2♂, 1893, Last ( BMNH) . 1♂, Maromandia, IV-1932 ( CMNH) ; 3♂, VI-1932 ( CMNH) . ' South Madagascar' , 1♂ ( BMNH) .

Distribution. Madagascar.

Remarks. There has been some uncertainty in whether to recognize this taxon as a subspecies of L. cinyras or a separate species. Based on the striking wing pattern and its close resemblance to L. labdaca labdaca , I follow Shields (1984a) and treat this taxon as a subspecies of L. labdaca . There are no signficiant differences in genitalia between the two subspecies.
