Material examined

Holotype: ♂ from Sierra Leone without abdomen ( BMNH).

Other specimens: 6 ♂, 10 ♀ from the Galápagos Islands: – Isabela: Sierra Negra, 11 km N Puerto Villamil, GPS: S 00° 87.613’, W 91° 00.903’; ± 15 km N P[uer] to Villamil. – San Cristóbal: El Junco, east side, GPS: 654 m elev[ation]., S 00° 53.734’, W 89° 28.727’. – Santa Cruz: Charles Darwin Research Station, Barranco, 20 m elev.; low agriculture zone, GPS: S 00°42.132’, W 90° 19.156’; NNW Bella Vista, GPS: 225 m elev., S 00° 41.293’, W 90° 19.665’; Finca Vilema, 2 km W Bella Vista; Los Gemelos. – Santiago: Aguacate [camp], 520 m elev.; Central [camp], 700 m elev. Deposited in CDRS and MHNG.

Diagnosis: The three straight lines of the hindwing, the basal two slightly interrupted ( Figs 33, 34View Figs 33 - 40), represent a unique diagnostic character with regard to the other Spilomelinae species of the Galápagos. The wingspan based on the Galápagos specimens examined is 19-21 mm.

Biology: The larva is recorded to feed on a wide variety of plants of the family Poaceae  , including rice, millet, sugar cane, and sorghum ( Robinson et al., 2014). In the Galápagos specimens have been collected from the littoral zone up to about 1000 m in elevation in a diverse range of habitats, and from February until May.

Distribution: Based on BMNH specimens this species is found in the Neotropical region in Argentina, Dominican Republic, and Jamaica. Patterson et al. (2015) record it from Florida, Texas and a few other states of the south east USA. It was described from Sierra Leone and has been recorded widely in Africa ( BMNH specimens; De Prins & De Prins, 2015). It is also known from India and Myanmar ( Robinson et al., 2014). On the Galápagos the species has been collected on Isabela, San Cristóbal, Santa Cruz, and Santiago.

Remarks: Marasmia trapezalis  was described from a male from Sierra Leone. The genitalia on the slide preparation of the lectotype of Botys creonalis Walker, 1859  ( BMNH), a synonym of M. trapezalis  , are identical to those of a dissected female from Sierra Leone, and of those of a female from the Galápagos ( Fig. 158View Figs 158 - 162). lectotype is designated here for Botys creonalis Walker, 1859  , described from Santo Domingo on the basis of two specimens. This female lectotype bears the following labels: 1-‘Type’ [circular, green bordered, typed], 2- ‘St. Dom. / 55.1’ [typed]; 3- ‘ Pyralidae  / Brit. Mus. / Slide. / 6402’ [typed in red, except for hand written number in black ink]; 4- ‘Photographed / B. M. Negative’ [typed, except for cross bar]; 5- ‘55. BOTYS CREONALIS  .’ [typed, folded]; 6- ‘Lecto/ type’ [circular, marine blue bordered, typed]; 7- ‘ LECTOTYPE / Botys  / creonalis  / Walker / Des. B. Landry, 2000’ [typed except for name and last two zeros]. The second syntype is designated paralectotype; it is a dissected female ( Pyralidae Brit. Mus. Slide.  6404).
