Family BOMBYCIDAE (13 species) Subfamily BOMBYCINAE (13 species) Bombyx incomposita van Eecke (Parts 15 & 16, p. 78).Sundaland. (Lowland, lower montane). Gunda ochracea Walker (Part 3, p. 80). Oriental tropics to Sundaland. Lowland. Note 81. Note 81. Zolotuhin & Witt (2009) have suggested that both Gunda ochracea and G. javanica are species complexes and that the latter is represented in Borneo by two closely related taxa still to be investigated. V.V. Zolotuhin (pers. comm.) has observed segregation on external features of two forms in Borneo and elsewhere according to the degree to which the forewings are falcate, considering that true javanica is the less falcate form; the more falcate form is illustrated in Part 3 (plate 9: 23). The latter occurs in Sundaland, Burma and Thailand (V.V. Zolotuhin, pers. comm.). Variability in the processes of the male eighth sternite was noted in Part 3. Zolotuhin & Witt considered in the light of this that G. richteri Weymer from Sulawesi should revert to full species status. Gunda javanica Moore (Part 3, p. 81). N.E. Himalaya to China and Sundaland. Lowland. Note 81. Note 81.

No precise habitat data available. Note 82. Note 82. Micrattacus sesostris Vuillot (1893, Bull. Soc. ent. France, p. 23) was described from a male in the Staudinger Collection from Labuan I., Borneo, collected by Waterstradt in 1890. The genus Micrattacus Walker is now restricted to the Neotropics, and sesostris was not referred to by Lemaire (2002) in his review of the genus. Seitz (1928, Gross‑Schmett. Erde 10: 517) listed the species, repeating the description in detail, but had not seen any material, stating that it was very unlikely that a genuine Micrattacus should exist in Borneo. The original description is parsimonious, without an illustration, but the only Micrattacus‑like Bornean species that is of the correct size and where the male generally matches the description is Gundasubnotata Walker. Attempts to locate the original material amongst the Staudinger Collection in MNHU, Berlin, have so far been unsuccessful. I am grateful to Wolfgang Nässig for drawing my attention to this mysterious Bornean taxon. Gunda proxima Roepke (Zolotuhin & Witt, 2009). N.E. Himalaya to S. China and Sundaland. No precise habitat data available. Note 83. Note 83. Zolotuhin & Witt (2009) recorded G. proxima from Borneo, but no material has been seen by the author, nor was it illustrated by Zolotuhin & Witt. There is material of proxima from Borneo in ZSM, Munich, including material from elsewhere on loan to the late W. Dierl (V.V. Zolotuhin, pers. comm.). The species is referred to briefly in Part 3 (p. 80). Zolotuhin & Witt considered that it is probably misplaced in Gunda. Ocinara albicollis Walker (Part 3, p. 83). Oriental tropics to Sundaland. (Lowland), lower and upper montane. Note 84. Note 84. Chung (2010) has described and illustrated the early stages of Ocinara albicollis Walker. The eggs are lozenge-like and laid in small groups. Early instars are white with a pair of dark spots on A2. Later instars are variegated brownish, with a horn on A8. The host plant was a golden cultivar of Ficus microcarpa (Moraceae), and was severely defoliated. A species of Brachymeria, a chalcid parasitoid, emerged from one of the cocoons. Robinson et al. (2001) noted F. religiosa as a host of albicollis, and all records for Ocinara and relatives are from Ficus. Ocinara bifurcula Dierl (Part 3, p. 83). Sundaland, N. Vietnam.
