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.
