A new record of Pachynoa Lederer, 1863 (Lepidoptera: Crambidae: Spilomelinae) from Laos

The genus Pachynoa is recorded for the first time in Laos with two species, Pachynoa xanthochyta (Turner, 1933) and Pachynoa thoosalis (Walker, 1859). These species are redescribed with illustrations of the adults and the genitalia, and their distribution is updated.
