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 View Figs 94-99 ). In female genitalia ( Fig. 154 View Figs 152-155 ), 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.
