Differential diagnosis This species has a yellow face ( Figure 11f), the alula is bare, narrower than costal cell, the wing is partly bare basally ( Figure 14d), and it does not have a mesonotal fringe. The abdominal pattern is identical to that of two other species, A. bicolorand A. loriae, with tergum 4 entirely black ( Figure 11c, d), but differs by the wing microtrichia as stated in the key. Asiobaccha bicolorand A. tripartitadiffer from A. loriaeby having the wing bare basally, easy to distinguish because both always have the cell CuP and anal lobe partly bare basally ( Figure 14c, d); sometimes A. loriaespecimens may have very small bare areas in the cell BM but the cell CuP and the anal lobe are always microtrichose. On the other hand, A. tripartitahas a more extensive microtrichia and bare basal areas of the wing are on basal 1/3 –1/2 cell BM only ( Figure 14d), while A. bicolorhas the cell R bare on basal 1/3 –1/2 and the cell BM bare on basal 1/2 or more ( Figure 14c).
Variation.Wing microtrichia is a bit less variable in this species: the bare area of cell BM varies between basal 1/3 to basal 1/2. Furthermore, a few specimens have costal cell bare very basally. The specimen from New Irelandhas the scutum entirely yelloworange. Wing colouration varies from very dark to almost hyaline. Length (N = 4).Body, 11.0 –13.0 (12.3) mm; wing, 10.0 –12.0 (11.1) mm.
Biology Greve and Ismay (1983)mentioned one species of Bacchawith the following information: ‘Ex Tiracola(Lep., Noctuidae) larva, Brevaturu, N.P., August, 1971 ’. The species mentioned is Baccha? [sic] papuanaHull. Thisrecord is compiled by Rojo et al. (2003)but with a different name, Allobaccha papuana(Hull, unpublished name).
In the opinion of this author, this species might refer to the unpublished name of Baccha papuanaHullthat appears in two specimens from Mafulu kept at the BMNH and CNC, although there is no information in the original labels about Tiracola. After studying the work of Greve and Ismay (1983), this citation may refer to a larva of a syrphid species parasiting a larva of TiracolaMoore, 1881( Lepidoptera: Noctuidae) from Barevaturu N.P. in Papua New Guinea. However, there is no species of Asiobacchaor Bacchathat parasitises butterfly larvae. Consequently, this record by Greve and Ismay (1983)may not refer to a species of Baccha, Allobacchaor Asiobaccha, or, on the other hand, it might indicate that the larva of Bacchawas preying on the Tiracolalarva and the adult emerged from a puparium.

Remarks Austen (1893)described Baccha sulicabased on two female specimens, but only the female from Sula Island had Walker ’s handwriting. Austen (1893)stated that he found the type of this species, but he could not find if it was already described. In my opinion, he decided to describe a new species based on Walker ’s handwriting. The most interesting fact is that Austen (1893)used the same argument to separate sulicafrom Baccha moluccanaas to separate bicolorfrom moluccana, but he did not compare his two new species. In the BMNH there are the two syntypesof Baccha sulica, but one belongs to A. bicolor(specimen from Sula Island and Walker ’s handwriting) and the other syntypebelongs to A. tripartita(specimen from Misool). Specimens from the New Irelandat ZMUC have a manuscript name given by P.H. van Doesburg, Baccha pleuralis, never published. Specimens from Mafulu have a manuscript name given by F. M. Hull, Baccha papuana, again never published. None of these three names is available. As already mentioned, A. tripartitamight belong to a widespread taxon and might include also A. loriaeand A. bicolor(see Remarks under A. bicolorand A. loriae). There are specimens of A. tripartitaand A. bicolorfrom the same localities, but, more interestingly, specimens of bicolorand tripartitafrom New Ireland Islandhave an orange scutum. Both females from Great Kai Island also have the scutum orange.
