Calliteara zelotica

Calliteara zelotica

Males of this species are similar to those of C. aphrasta Collenette , with lightly fasciated and irrorated, bone-coloured forewings and darker brown hindwings. They are larger, the forewings more elongate and the hindwings darker brown, less variegated. The forewing postmedial has the lunules at one third and two thirds somewhat stronger, whereas in aphrasta they are not emphasised. This is also seen in the female, which again has a more uniform hindwing with only faint marginal flecks compared to the prominent dark ones of the forewing; in aphrasta they are equally dark.

Taxonomic notes. The species has genitalic features that indicate a relationship to cerigoides and to the horsfieldii group rather than to the angulata group as suggested by Holloway (1982b). These features are: a pair of small spine-like juxta prongs; a blunt spur at the aedeagus apex. The serrations on the interior margin of the valve are coarse as in cerigoides.

There is some confusion over the identity of zelotica. The original description of hamilleter obviously refers to the species diagnosed here, but the genitalia differences suggest that the ‘zelotica’ specimen under consideration was aphrasta, particularly with regard to juxta spines. The specimen labelled as holotype has facies as in hamilleter and a cross-reference to genitalia slide 134 which is of aphrasta, but labelled as type of zelotica. A second male specimen of the same provenance, but much more worn, is of aphrasta but has a cross-reference to slide 135 which matches hamilleter. The two preparations were mounted from dissections made by W.H.T. Tams in 1932 and probably retained in tubes at that time. It is likely that the two have been transposed at some time between 1932 and 1953, leading to the confusion. It is clear from the original description that the holotype is the ‘hamilleter’ male and not the ‘aphrasta’ one. The allotype female of zelotica is also aphrasta.

Geographical range. Peninsular Malaysia, Sumatra, Borneo.

Habitat preference. Of the four specimens taken in recent surveys, three were from primary lowland forest (in the Tawau district of Sabah and the Ulu Temburong area of Brunei) and one was from secondary forest and coastal vegetation at Seria, Brunei.
