Subfamily Chrysauginae

Caphys biliniata (Stoll, 1782)

Identified by comparison with the type and NHMUK series. This seems to be the only species of this appearance in Tobago, but there are two or three confusingly similar species found in Trinidad, which might also be found in Tobago.

Charlotteville , at light: 15♂, 2♀ 14–21 Mar 1979 (D. Hardy & W. Rowe) ; 2♀ 15–19 Jun 1998 (Roger Hammond & Piers Meynell) [ UWIZM.CABI.7466–67] ; ♂ 24 Oct 2015 (K. Sookdeo photo, Tobago Moths 1) ; Hillsborough Dam , black light: ♀ 21 Mar 1979 (D. Hardy & W. Rowe) ; Roxborough , 6 mi. N on Bloody Bay Road, black light: ♂ 20–21 Mar 1979 (D. Hardy & W. Rowe) ; Scarborough , Marden House, MVL: 2♂, ♀ 9 Jan 1982 (M.J.W. Cock) [ MJWC] ; Tobago: ♂ 1–4 Feb 1931 (Capt. A.K. Totton) [ NHMUK]

Carcha hersilialis Walker (see Tosale oviplagalis )

Galasa cuprealis (Hampson, 1906)

Identified by comparison with the type (NHMUK, Paraguay) and NHMUK series.

Crown Point, at light: ♀ 15–17 May 1981 (M.J.W. Cock) [MJWC]

Galasa ditrogalis (Hampson, 1906)

Galasa ditrogalis (Hampson) : Mettam (1999)

Identified by comparison with the type (NHMUK, French Guyana) and NHMUK series. Charlotteville, at light: ♂ 15–19 Jun 1998 (Roger Hammond & Piers Meynell)

Hyperparachma sp. ( Figures 1–2 )

Identified by comparison with the USNM series as Hyperparachma sp. D , which was curated by E.D. Cashatt as part of his unpublished dissertation ( Cashatt 1969). Figure 1 shows the single Tobago specimen alongside one from Trinidad ( Figure 2 ) in better condition and more heavily marked.

Speyside, MVL: ♂ 14–17 May 1982 (M.J.W. Cock) [MJWC] ( Figure 1 )

Nachaba diplagialis (Hampson, 1906)

Chrysauge flavelata (Stoll) : Mettam (1999) [misidentification]

Identified by comparison with the types (♂ Surinam, ♀ Rio) and NHMUK series. In comparison Chrysauge flavelata (Stoll) (TL Surinam) has a narrow dark margin on the hindwing, and does not seem to occur in Trinidad or Tobago.

Charlotteville, at light: ♀ 15–19 Jun 1998 (Roger Hammond & Piers Meynell) [MJWC]

Tosale oviplagalis (Walker, 1866)

Tosale oviplagalis (Walker) : Longstaff (1912)

Identified by comparison with type (NHMUK, ♀?locality) and NHMUK series. The female can be mis- identified as Carcha hersilialis Walker , a species which does not seem to occur in Trinidad or Tobago, but the male has distinctive large black areas on the disc of the dorsal hindwing and ventral forewing, which are not found in C. hersilalis .

Charlotteville, at light: ♂ 14–21 Mar 1979 (D. Hardy & W. Rowe) [ USNM, as Carcha hersilialis ] ; ♀ 15–19 Jun 1998 (Roger Hammond & Piers Meynell) [ MJWC] ; Cocoa Wattie: ♂, ♀ 8 Apr 1907 (G.B. Longstaff) [ OUNHM, det. H. Druce 1908]
