Remarks.

Based on the available figures, adults of both sexes which were reported by Haneda (1950) from Singapore, and repeatedly mentioned in subsequent studies (e.g., Harvey 1952; Haneda 1955, 1985; Lloyd 1971, 1978; Crowson 1981; Kawashima et al. 2010), are probably members of Haplocladon . We are aware of several Haplocladon specimens from Singapore (deposited in NHMUK) but no Diplocladon are known from that area.
