SIMILAR SPECIES

Angustalius malacellus (Duponchel, 1836) .

DIAGNOSIS

This species is a commonly encountered Crambinae in South-East Asia. Accurate identification to separate it from A. malacellus is only possible by examination of male genitalia ( Fig. 109 ): The gnathos is longer, the posterior margin of the sacculus is denticulate and lacks the ventral protrusion as in A. malacellus , the vinculum is proximally rounded, while it is pointed in A. malacellus , and the cornutus on the vesica is smaller than in A. malacellus ( Błeszyński, 1965) . Błeszyński (1965) could not find the specific differences in female genitalia between A. malacellus (Duponchel, 1836) and A. malacelloides (Błeszyński, 1955) . A possible character separating A. malacelloides ( Fig. 165 ) from A. malacellus is the lack of the broadened pouch of the ductus bursae in A. malacelloides .

DNA BARCODING

A maximum intraspecific p-distance of 0.6% is observed between sample MFNLEP-PYRALPHIL08-G12 from Luzon (Zambales) and the two samples from Borneo. The specimen MFNLEP-PYRALPHIL08-F12 (Panay) and MFNLEP-PYRALPHIL08-G12 (Luzon, Zambales) both represent a unique haplotype, while specimens MFNLEP-PYRALPHIL08-E12 (Panay) and MFNLEP-PYRALPHIL07-D08 (Luzon) share the haplotype with specimens from Borneo, Papua New Guinea, and New South Wales, Australia (see Fig. 179a ).

DISTRIBUTION

AUSTRALIA; CHINA; INDIA; MALAYSIA; PHILIPPINES: Luzon (Benguet, Zambales), Panay; NEW ZEALAND. In the Philippines, the specimens were collected at altitudes between 250 and 900 m, with one single specimen encountered at 2350 m.
