Taxonomic changes in the Neotropical wasp moths, Euchromiina and Ctenuchina (Lepidoptera, Erebidae, Arctiinae, Arctiini) relating to the fauna of Trinidad & Tobago, with descriptions of new species Author Cock, Matthew J.

BIN: BOLD:AAK1636. Cramer (1775–1782, p. 4, pl. 2 D, E) described C. helymus from Suriname , with two illustrations representing dorsal and ventral views. There is no known type material. Cerda (2008) treats this species from French Guiana and illustrates the adult male in dorsal view and male genitalia. Kaye & Lamont (1927) recorded C. helymus from Trinidad on the basis of an undated Lamont specimen from Palmiste. There is a female Phoenicoprocta vacillans trinitatis morph (i.e. the female morph of P. vacillans that Rothschild (1912) described as Antichloris trinitatis with plain dark forewings—see Fleming (1957)) , with an identification label as C. helymus from Lamont’s collection in NMS. We accept this misidentified specimen as the basis for Kaye & Lamont’s (1927) record of C. helymus from Trinidad , and there have been no other records of C. helymus from the island. Fleming (1957) described C. craneae from Trinidad , based on a type series of 30 males and 24 females . The holotype can be seen on-line ( AMNH 2022a ). This species has subsequently been referred to in Trinidad by Beebe & Kenedy (1957) , Blest (1964) and Cock (2003) . Based on the Trinidad material examined, females typically have three forewing spots ( Fig. 6 ), whereas the spot in space 3 (M 3 -Cu 1 ) is reduced or sometimes absent in males ( Fig. 4 ). In a parallel case to C. aterrima above, DNA barcodes ( Fig. 1 ) and the male genitalia of Trinidad material show that C. craneae is the same as C. helymus as found in French Guiana ( Cerda 2008 ). Similarly, specimens with the forewing plain black are not found in Trinidad , and the white spotted form is not found in French Guiana.Accordingly, we consider it appropriate to treat C. craneae as a subspecies: C. helymus craneae Fleming new status . In Trinidad , C. helymus craneae and C. aterrima tripunctata are both common and can be easily confused. However, as Fleming (1957) pointed out, they can be separated by the green markings on the abdomen. The dorsal green band starts on the anterior margin of abdominal segment 1 in C. aterimma ( Figs. 2 , 3 ), but on the anterior margin of abdominal segment 2 in C. helymus ( Figs. 4–6 ); further C. helymus has a white spot on either side of this line on A1, not present in C. aterimma .
