NOCTUIDAE that have been misplaced in the ARCTIIDAE
View Image Gallery of Noctuidae

The taxa discussed in the remainder of this part, Camptoloma Felder and the Aganainae (Hypsinae), have been placed in the Arctiidae until relatively recently, or even in distinct families. More thorough investigations conducted in the past decade or so have done much to clarify the derived features that define the major noctuoid families, with the result that several genera or small groups of genera have had to be reclassified. This work is continuing so stability of the current classification cannot, yet be assured.

Both the following groups lack the arctiid character of a tymbal organ and possess the noctuid feature of a post-spiracular counter-tympanal sclerite combined in Aganainae with a prespiracular hood. Other features will be noted individually.

The two groups are included in this part for the convenience of users of the series who will probably expect to find the groups in their ‘old positions’

The taxon Caranusca rubrifera Walker, described from Sarawak (J. Linn. Soc. Lond. (Zool.) 6:100-101) as ‘allied’ to Hypsa, remains enigmatic. It is still assigned to the Aganainae by Watson, Fletcher and Nye (1980). The type should be in the University Museum, Oxford, but has not been located there. The description does not readily fit any noctuoid known to occur in Borneo: body thick (1.5cm long), abdomen conical; wings narrow, forewings apically quadrate (span 4cm); antennae filiform, ciliate; general colour ferruginous (e.g. forewings) but head, thorax and base of the abdomen broadly red; forewing with oblique ashy grey fascia from apex to dorsum at two thirds; hindwing bright yellow, apically and marginally ferruginous brown; dorsum of hindwing greyish.

The genus Baroa Moore is also dubiously arctiid for the reasons stated on
Baroa siamica Hampson.
