Streblote dorsalis (Walker, 1866) (Figs 8–10, 26, 38–40) Megasoma dorsalis Walker, 1866, List of the specimens of lepidopterous insects in the collection of the British Museum, 35, 1947. Type locality: Borneo. Holotype female (NHML), not male as stated by Walker. = Streblote helpsi Holloway, 1987, Moths of Borneo, 3, 25. Type locality: [Borneo] Brunei, Sungai Selanjak. Holotype male (NHML). Taxonomic note. 1. The “male” mentioned in the original description is an error. Walker described a female which is evident from the coloration, the size of the body, and the wings of the specimen. 2. The taxon is known to us from 4 adults originating from Borneo: holotype female (Fig. 8), holotype male of S. helpsi (Fig. 9), and a pair from SNHM (male on Fig. 10). Here we suppose that specimens from Belitung (a pair from SMNH, Figs 11–12, and one female from NBCL) and Sulawesi (two females from NBCL, Fig. 13; earlier mentioned by Zolotuhin & Holloway, 2006) may represent two new species externally resembling and genetically close to S. dorsalis. Barcoding and detailed morphologic study are necessary. 3. The species resembles very much S. castanea from the Philippines, a genetic study is necessary to check their relationship due to the lack of significant morphologic differences.
