Arctornis galene Toxopeus comb. n.

Redoa galene Toxopeus, 1948: 460.

Redoa galene Toxopeus; Mackey, 1984: 9.

Diagnosis

The facies is much as in prasioneura except the frons is broadly rufous in a square from the level of the antennae to just below the top of the compound eyes. The palps are yellow (paler ventrally) with a few brownish scales at the apex. The legs are spotted as in prasioneura but more strongly so. In the male genitalia, the uncus is triangular as in ungula though less narrowed apically and lacking the pair of pockets. The valve apex is rather square. The harpe is evenly and gently downcurved, somewhat expanded subbasally on the ventral margin, and tapering to a point near the very apex. It is extensively scobinate along its ventral half.

Geographical Range

Java, Sumatra (Schintlmeister, MS), Borneo.

Habitat Preference

Two specimens are from a limestone area, taken in lowland and lower montane forest zones, and two others are from lowland swamp forest.

Biology

Toxopeus (1948) indicated the host-plant to be Cinnamomum (Lauraceae) in Java.

Taxonomic notes

The identities of the taxa A. galene Toxopeus (t. loc. Java) and A. galanthina Toxopeus (Java) were found to raise questions when both holotypes and the allotype male of the former were dissected. Mackey (1984) had already dissected a male parallotype of galene, where the holotype is female (Fig 106). The genitalia of the species attributed to galene and those of the paratype examined by Mackey match those of the holotype of galanthina (Fig 104). The valves in galanthina are somewhat more elongate and narrower than in Bornean material, but the allotype male of galene (Fig 105) has the harpe almost straight. Possibly these differences are within the range of variation of the species in Java, but this needs further investigation, as does the relationship of the holotype female of galene to males; perhaps only molecular data will provide clarification. The typical race occurs through most of the Philippines but ssp. fuscata Schintlmeister & Lourens (2010) occurs in Palawan.

Mackey (1984) had already dissected a male parallotype of galene, where the holotype is female (Fig 106). The genitalia of the species attributed to galene in Part 5 and those of the paratype examined by Mackey match those of the holotype of galanthina (Fig 104). The valves in galanthina are somewhat more elongate and narrower than in Bornean material, but the allotype male of galene (Fig 105) has the harpe almost straight.
