Abstract
A new species of Sacada from northern Thailand is described: Sacada chaehomensis sp. nov. Pellinen & Zahiri (Lepidoptera: Pyralidae, Pyralinae). Morphological characters and DNA barcode data are provided for the new species, with a morphological comparison to S. dzonguensis and S. umtasorensis, and a DNA-barcode comparison to S. ragonotalis and S. albioculalis, respectively. After this addition, the current number of valid species in the genus Sacada is 43.

Sacada chaehomensis Pellinen & Zahiri, sp. nov.
Diagnosis: Sacada chaehomensis sp. nov. is morphologically similar to S. dzonguensis Singh, Kirti & Ranjan, 2020 and S. umtasorensis Singh, Kirti & Ranjan, 2020. Diagnostic male characters of these three species are indicated on Figs 2–7 (females of these three species are unknown). Forewing postmedial line is straight on costa and medial line is straight in S. chaehomensis sp. nov. (postmedial line curved and medial line angled in S. dzonguensis; postmedial line straight and medial line angled in S. umtasorensis). With regard to diagnostic male genitalia characters, see Figs 5–7.
Etymology: The species is named after its type locality, Chae Hom, in Lampang province, Thailand.
Biology: The single known male was collected in May 2020 at 340 m altitude; it was attracted to light in forest with diverse tree species, interspersed with small vegetable plantations (Fig. 9). Immature stages are unknown.
Distribution: The only specimen was collected in Lampang (Chae Hom) in northern Thailand.
