Hemithea antigrapha Prout
Hemithea antigrapha Prout, 1917, Ann. Mag. nat. Hist. (8), 20: 122.
Diagnosis
The facies is similar to that of insularia but the genitalia are more as in Hemithea marina Butler with the most dorsal process on the valve rhomboidal.
In marina this process is deeper, the saccular one more robust and bulbous: the socii in marina are thicker.
The marina female has the ostium broader, more setose, with a semicircular, scobinate lamella antevaginalis.
Geographical range
N.E. Himalaya, Peninsular Malaysia (FRIM colln), Borneo.
Habitat preference
The species is rare, four specimens having been taken during the Mulu survey from: lowland alluvial forest; forest on limestone at 250m; kerangas forest at 150m on a river terrace; lower montane forest at 1000m.
