SYNTYPES 1 [♂] Ceylon [Sri Lanka], «52.62» (pres. by R. Templeton); 1 North India (ex coll. Stevens); 2 [♂] North India, «43.10» (ex coll. James); 2 [1♂,1?] [Bangladesh:] Silhet [Sylhet], «45.107» (ex coll. Rev. J. Stainforth); 2 [1♀,1?] North India, «43.58» (pres. by E. Doubleday); 1 Nepaul [Nepal] (pres. by Gen. Hardwicke); 1 North China (ex coll. Fortune) [NHMUK]. Some of the above listed specimens are unavailable for selection as the lectotype as they were described as "var. β" (at least one is a misidentified Theretra oldenlandiae oldenlandiae). Of the ten syntypes and specimens of “var. β”, only the Templeton, both James, one Stainforth and one Doubleday have so far been located in NHMUK. There is a further male with an illegible label that may be one of the other syntypes. Of these, only one specimen matching “var. β”, one of the two James specimens, has so far been found in NHMUK.

A Boisduval manuscript name made available by Walker. For some reason, Moore , in Horsfield & Moore, Cat. Lepid. Ins. Mus. East India Company 1: 278, considered Boisduval's manuscript name, which was made available by Walker, 1856, List Specimens lepid. Insects Colln Br. Mus. 8: 143, as Chaerocampa silhetensis, to be “inapplicable” and “cancelled” it. It is possible that he believed Horsfield's earlier (1826) manuscript name, Chaerocampa bisecta, should have been given priority. Moore therefore listed Chaerocampa silhetensis incorrectly as a junior synonym of Chaerocampa bisecta.
