Material examined: 5 ♂, 7 ♀, 43 of undetermined sex from the Galápagos Islands. – Española: Bahía Manzanillo  ; Las Tunas trail, 100 m elev[ation]. – Floreana: Punta Cormoran; Charles [no precise locality]. – Isabela: Albermarle, Cobea [?] Settlement; V[olcan]. Darwin, 300 m elev.; NE slope Alcedo, ca. 400 m up (S) Los Guayabillos camp, GPS: 892 m elev., S 00° 25.208’, W 91° 04.765’; V. Darwin, 1000 m elev. – San Cristóbal: Chatham [no precise locality]. – Santa Cruz: Academy Bay, Charles Darwin Research Station; Charles Darwin Research Station; Horneman Farm, 200 m; Horneman Farm, 220 m elev.; [no precise locality], reared from larva ex Sesuvium portulacastrum  . – Santiago: Jaboncillo [camp], ± 850 m elev. Deposited in BMNH, CAS, CDRS, MCZ, and MHNG.

Diagnosis: Measuring between 17 and 21 mm in wingspan in the Galápagos this species is most similar to Hymenia perspectalis (Hübner)  ( Figs 22, 23View Figs 17 - 24) and Cryptobotys zoilusalis (Walker)  ( Figs 10, 11View Figs 9 - 16), both treated above. Spoladea recurvalis (Fabricius)  ( Fig. 63View Figs 57 - 64) is somewhat paler brown than H. perspectalis  . Their white markings differ in the forewing by the wide median fascia from the dorsum touching the discocellular stigma in S. recurvalis  , thin and not touching the discocellular stigma in H. perspectalis  , and on the hindwing by the wide and evenly margined fascia of S. recurvalis  compared to the thin fascia presenting a median bilobed projection medially on the external margin in H. perspectalis  . Cryptobotys zoilusalis (Walker)  also has white to cream fasciae, but these are very thin.

Biology: The larva of this species is polyphagous and has been recorded on a wide variety of plants, for example Aizoaceae  ( Trianthema  sp.), Amaranthaceae  ( Alternanthera  sp., Amaranthus  sp., Celosia  sp., Gomphrena  sp.), Arecaceae  [ Chrysalidocarpus  (= Dypsis  ) sp.], Asteraceae  ( Chrysanthemum  sp., Eupatorium  sp.), Chenopodiaceae  ( Beta  sp., Chenopodium  sp.), Convolvulaceae  ( Ipomoea  sp.), Fabaceae  ( Glycine  sp., Vigna  sp.), Nyctaginaceae  ( Boerhavia  sp.), Poaceae  ( Zea  sp.), Portulacaceae  ( Portulaca  sp., Spinacia  sp.), Solanaceae  ( Lycopersicon  sp.), etc. ( Robinson et al., 2014). In the CDRS collection there is a pair of specimens associated with a number 69, which refers to a notebook entry mentioning Sesuvium portulacastrum  (L.) L. and Portulaca oleraceae  L. ( Aizoaceae  ) as hosts in the Galápagos. Moths in the archipelago have been collected from sea level up to 1000 m in elevation in pristine as well as anthropized habitats, from February to May and in December.

Distribution: Based on the literature (for example De Prins & De Prins, 2015; Shaffer & Munroe, 2007; Zimmerman, 1958) and museum specimens this species is widespread around the world under warm climates, but it is also probably resident in Southern Europe and occasionally reaches northern Europe ( Slamka, 2013) and south-eastern Canada ( Patterson et al., 2015). In the Galápagos it has been collected on the islands of Española, Floreana, Isabela, San Cristóbal, Santa Cruz, and Santiago.

Remarks: I have identified a Galápagos specimen of this species by comparing it with BMNH identified material, including the types of some of its synonyms. The type was not examined as it is lost ( Clarke, 1986).
