MATERIAL 3 ♀ (detailed information on Table S1; https://doi.org/ 10.5061/dryad.b8gtht7mh). DIAGNOSIS Chilo infuscatellus, also known as the Yellow Top Borer, have narrow brownish forewings medially speckled with dark brown and snow white hindwings. This species can be separated from other Chilo species by the presence of a conspicuous cornutus on the vesica of the male genitalia (Fig. 96). In female genitalia (Fig. 154), the following characters distinguish this species from congeneric species: ostial pouch distincly incised; ductus bursae devoid of swellings and sclerotized markings; corpus bursae with one signum (Anon, 2019; Bleszynski, 1970c). DISTRIBUTION AFGHANISTAN; INDIA; INDONESIA, MYANMAR; PHILIPPINES: Luzon (Benguet; Zambales); TAIWAN; TAJIKISTAN; TIMOR (Bleszynski, 1970c). Collected at altitudes between 150 and 500 m on the Philippines. DNA BARCODING A maximum intraspecific p-distance of 0.3% is observed between MFNLEP-PYRALPHIL11-B01, MFNLEP-PYRALPHIL11-A01, and MFNLEP-PYRALPHIL11-G01, all from Luzon (Zambales). The haplotypes of Luzon are most closely related to those found in Thailand (see Fig. S2e). A maximum intraspecific divergence of 7.1% is observed in specimen LSTEM114-18 from Java identified as Chilo infuscatellus. REMARKS Błeszyński (1970) investigated one female specimen from Klondyke on Luzon, Philippines.
