javana Macquart, 1851 , Hydrotoea

Hydrotoea javana Macquart, 1851b: 235 ( 1851d: 262) , pl. 24, fig. 4. Lectotype ♂ (not ♀, as stated by Macquart),

“Java. Collection de M. Bigot.” (Java), by present designation, in OUMNH.

MATERIAL. — There is 1 ♂ syntype in the part of the Bigot collection that is now in OUMNH. It is extremely damaged, but is in fact an immature ♂ (as pointed out by Emden 1965: 610), and not a ♀ as stated by Macquart (and also by Stein 1907b: 277). The head is squashed almost flat, so that the occiput appears to be the “frons” and this must have misled Macquart and Stein into thinking that they were studying a typical broad-fronted ♀; the thorax is rather compressed and is covered with some kind of shining glue or grease, and the scutellum is also damaged; left wing loose; all legs present; the abdomen is present and confirms that this is in fact a ♂. It is labelled by Macquart “ Hydrotoea / javana. ♀ / Macq. n. sp.”, and stands over a Bigot drawer label “ H. javana . ♀. / Java. Macq.”. I have labelled it and designate it herewith as lectotype.

CURRENT IDENTITY. — This is a species of the genus Heliographa Malloch, 1921 , and an older name for the species previously known as Heliographa tonsa (Stein, 1909) , as suggested by Emden (1965: 610) and Pont (1977b: 503). This synonymy is supported by the very short-haired arista, the shape of wing-cell r 4 + 5, the presence of setulae on the sides of scutellum near base, and the bare sternite 1.
