Subtribe Ctenuchina

Classification and nomenclature follow Fleming (1959) and the NHMUK collection ( Beccaloni et al. 2003) for species not covered by Fleming.

Anycles dolosa (Walker, 1854)

Identified by comparison with the type (NHMUK, ♀ Brazil, no abdomen) and NHMUK series. Fleming (1959) and Field (1975) treated this species in Amycles Herrich-Schäffer, 1855 , a synonym of Anycles Walker, 1854 (Watson et al. 1980). This material from Tobago may be a distinct subspecies (or species); compared to Trinidad material, it differs due to a stronger red spot posterior to the eye, the UPS is more intensely black, the green stripes on abdomen broader, and the white spot posterior to the tympanic hood green rather than white.

Charlotteville-Speyside Ridge, to Heliotropium : 6♂ 15 May 1982 (M.J.W. Cock) [MJWC]

Correbidia assimilis (Rothschild, 1912) ( Figure 25 )

Identified by comparison with the type (NHMUK, ♂ Venezuela) and NHMUK series. Fleming (1959) made C. similis (Rothschild, 1912) a synonym of C. assimilis ; I suspect both taxa will prove to be synonyms of C. notata (Butler, 1878) .

Charlotteville, at light: ♂ 24 Oct 2015 (K. Sookdeo photo, Tobago Moths 3; Figure 25 )

Episcepsis hypoleuca Hampson, 1898

Identified by comparison with the type (NHMUK, ♂ Costa Rica) and NHMUK series. This species has also been placed in Epidesma . One of a group of confusingly similar species, which would benefit from revision.

Nr. Speyside, MVL: ♂ 16 May 1982 (M.J.W. Cock) [MJWC]

Eucereon latifascia sensu Hampson, 1898 nec Walker, 1856 ( Figures 28-31 )

This seems to be an undescribed species, also known from Trinidad ( Figures 28-31 ). Initially I identified it as E. latifascia Walker from Fleming (1959) who recognised that the holotype is a different species to the species treated as E. latifascia in his paper and in NHMUK. I have examined the holotype in OUNHM (Para, ♂) and it is clearly not the same species, having slightly different markings on the forewing, a hyaline discal hindwing rather than translucent, and the red lateral markings on abdomen extend anteriorly one segment in the type and two in this species. Hampson’s (1898, pl 16.14) illustration of what he treats as E. latifascia from Peru is closer to the Trinidad material than to the holotype, e.g. with regard to the hindwing and abdominal markings. I have found no matching type material in NHMUK or USNM.

Englishman’s Bay, at light: ♀ Jun–Dec 2009 (J. Ingraham) [ UWIZM.2015.15.116]

Eucereon mitigata Walker, 1857

Identified by comparison with the lectotype ( OUMNH, ♂ Brazil). This species has been incorrectly treated as E. reticulatum Butler , but as suggested by Fleming (1959) and clarified by Pinheiro (2016) that was based on a misidentification.

Englishman’s Bay, at light: ♂ Jun–Dec 2009 (J. Ingraham) [ UWIZM.2015.15.115]

Eucereon sylvius (Stoll, 1790)

Identified by comparison with the neotype ( NHMUK, ♂) and NHMUK series.

Nr. Speyside, MVL: ♂ 16 May 1982 (M.J.W. Cock) [ MJWC]

Eucereon maia Druce, 1884

Eucereon maia Druce : Longstaff (1912)

Identified by comparison with the type ( NHMUK, ♀ Costa Rica) and NHMUK series. Charlotteville , at light: ♂ 15–19 Jun 1998 (Roger Hammond & Piers Meynell) [ MJWC] ; Cocoa Wattie : ♂ 8 Apr 1907 (G.B. Longstaff; TESL 1908, 53–7) [ OUNHM]. Note, Longstaff (1908) deals with butterflies only and does not mention this specimen, but it is listed in Longstaff (1912) .
