Cock, Matthew J. W., 2017, A preliminary catalogue of the moths (Lepidoptera except Papilionoidea) of Tobago, West Indies, Insecta Mundi 2017 (585), pp. 1-58 : 32-33

Subtribe Arctiina

Nomenclature follows Vincent and Laguerre (2014).

Agaraea semivitrea Rothschild, 1909

Identified by comparison with a syntype (NHMUK) and NHMUK series.

Hillsborough Dam, black light: 2♂ 21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; Speyside, MVL: 14–17 Sep 1982 (M.J.W. Cock) [ MJWC]

Ammalo helops (Cramer, [1776])

Identified by comparison with the NHMUK series.

Englishman’s Bay, at light: ♂, ♀ Jun–Dec 2009 (J. Ingraham) [UWIZM.2015.15.105-106]

Amphelarctia priscilla (Schaus, 1911)

Watson (1971) illustrates the male lectotype and its genitalia, which I have compared with those of a Trinidad male.

Englishman’s Bay, at light: ♂ Jun–Dec 2009 (J. Ingraham) [UWIZM.2015.15.107]

Halysidota orientalis Rothschild, 1909

Identification by comparison with the NHMUK series and Watson (1980). These records from Tobago are the first from the island, but not surprising since H. orientalis occurs in both Trinidad and Grenada (Watson 1980).

Charlotteville , at light: ♂ 14–21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; Englishman’s Bay , at light: ♂ Jun–Dec 2009 (J. Ingraham) [ UWIZM.2015.15.108] ; Roxborough , 6.5 mi N on Bloody Bay Road, at light: ♀ 20–21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; Nr. Speyside , to Heliotropium by night: ♂ 15 May 1982 (M.J.W. Cock) [ MJWC]

Hypercompe trinitatis (Rothschild, 1910)

This species was originally described from Trinidad as a subspecies of Ecpantheria icasia (Cramer) , but Watson and Goodger (1986) raised its status to that of a valid species. Identified by comparison with the NHMUK series.

Tobago: 2♂ (E. Bourke) [OUNHM]

Trichromia leucoplaga Hampson, 1905

Identification by comparison with a type (NHMUK, French Guiana) and NHMUK series. Englishman’s Bay, at light: ♂ Jun–Dec 2009 (J. Ingraham) [UWIZM.2015.15.109]

Lophocampa seruba (Herrich-Schäffer, [1855]) parva (Rothschild, 1909)

Identification by comparison with the NHMUK series.

Charlotteville, at light: 5♂, 1♀ 14–21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; Hillsborough Dam, black light: 2♂ 21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; Nr. Speyside, MVL: 2♀ 16 May 1982 (M.J.W. Cock) [ MJWC]

Pareuchaetes pseudoinsulata Rego Barros, 1956

Identification based on Cock and Holloway (1982).

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

Utetheisa ornatrix ornatrix (Linnaeus, 1758)

Utetheisa ornatrix (Linnaeus) : Longstaff (1912)

Identification by comparison with the NHMUK series.

Cocoa Wattie : ♂ 7 Apr 1907 (G.B. Longstaff) [ OUNHM] ; Crown Point , at light: 15–17 May 1981 (M.J.W. Cock) [ MJWC] ; Scarborough : 2♀ 3 Apr 1907 (G.B. Longstaff) [ OUNHM], ♂ 4 Apr 1907 (G.B. Longstaff) [ OUNHM] ; Tobago: 3♀ (E. Bourke) [ OUNHM]

Virbia medarda (Stoll, 1781)

Virbia sp. : Longstaff (1912)

Identification by comparison with the NHMUK series and MJWC collections from Trinidad. I believe a single variable species is present in Trinidad and Tobago, to which several names have been applied. Thus, Kaye and Lamont (1927) probably correctly treated mentiens Walker (TL Venezuela) and birchi Druce (TL Trinidad, Colombia, an all ♀ species in NHMUK) as synonyms of medarda Stoll (TL Surinam), although Watson and Goodger (1986) and Vincent and Laguerre (2014) treat them as valid species. Pending a full investigation, I do not formally synonymise these here, but do use the oldest available name.

Charlotteville , at light: ♂ 24 Oct 2015 (K. Sookdeo photo, Tobago Moths 3) ; Cocoa Wattie : ♂ 8 Apr 1907 (G.B. Longstaff) [ OUNHM, as Virbia mentiens Walker ] ; Charlotteville , at light: ♂, ♀ 14–21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; 2♂ 15–19 Jun 1998 (Roger Hammond & Piers Meynell) [ UWIZM.CABI.7458, NHMUK] ; Englishman’s Bay , at light: 2♀ Jun–Dec 2009 (J. Ingraham) [ UWIZM.2015.15.110-111] ; Hillsborough Dam , black light: 10♂, 1♀ 21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; Roxborough , 6.5 mi N on Bloody Bay Road, at light: 4♂, 2♀ 20–21 Mar 1979 (D. Hardy & W. Rowe) [ USNM] ; Speyside , MVL: ♂ 14–17 May 1982 (M.J.W. Cock) [ MJWC]
