First host record for the genus Canalirogas

A reared female specimen of Canalirogas was located in the NHM bearing the following labels: ‘‘N SUMATRA Temburn, Tarokaro XII 1989 ’’, ‘‘Tube 1. ex Nettle Caterpillar on clove, CIE A20831 ’’, ‘‘Pres by Comm Inst Ent B.M. 1990-1’’ and ‘‘ Aleiodes spilonotus (Cameron) det A.K. Walker’’. Mounted on the same pin, glued to a card, is an emerged rogadine mummy ( Figure 28 ) of an unidentified, strongly ornamented, lymantriid larva (Shen-Horn Yen, personal communication). Although the term nettle caterpillar is usually applied to members of the Limacodidae it may also be applied more loosely to include various spiky or hairy larvae, especially when they are urticating (as are the larvae of many Lymantriidae ).

In the key to the 11 known species of Canalirogas species by van Achterberg and Chen (1996), the specimen runs to couplet 10 and fairly easily can be run out to C. balgooyi van Achterberg and Chen , the type species of the genus, except that it has fairly well-developed antero-lateral convexities on metasomal tergites 3 and 4. We examined the female type specimen of Aleiodes spilonotus (Cameron) (NHM; 3.c. 222), the species that the specimen had been identified as, and concur that it is very similar to the reared specimen and also belongs to Canalirogas , hence Canalirogas spilonotus (Cameron) comb. n. From the large section in van Achterberg and Chen (1996) on the morphological and colour variation observed in balgooyi , together with its large geographic range [ China, Nepal, India, West Malaysia (the type locality), Borneo Island, Sumatra, and Bali] it is possible that this is a species aggregate rather than a single species, and therefore we choose neither to synonymize balgooyi with spilonotus nor to state firmly that the specimen dealt with here is indeed either of these nominal species. The reared specimen is illustrated here in Figures 10–17 .
