Berta copiosa Prout, 1917, Novit. zool., 24: 303.
Berta chrysolineata zygophyxia Prout,
1912, Genera Insectorum 124: 234, partim (see below)
Diagnosis. The relatively large white patches medially and postmedially
distinguish this species from other Berta. See the diagnosis and
taxonomic note for B. zygophyxia Prout.
Taxonomic notes. This species is closely related to B. hemisponsa Prout stat.
n. from the Bismarcks and Solomons, the latter possibly merely a subspecies of copiosa
rather than of B. zygophyxia Prout as originally described. It has a
similar deep cleft on the eighth sternite, longer but similar spines on the
juxta, a sinuous valve, though lacking the central angle, and a rather quadrate,
rather than curved and serrate, process distal to the groove on the valve.
Geographical range. N.E. Himalaya; Borneo, Sumatra, Bali.
Habitat preference. Four specimens have been taken in recent surveys from: coastal
forest at Seria in Brunei; forest on limestone at 250m on the lower slopes of G.
Api; at 1620m on G. Kinabalu (noted partim as B. chrysolineata by
Holloway (1976)); in a Pinus caribaea plantation near Brunei in the
lowlands of Sabah by Dr Chey Vun Khen.
