Diagnosis. See Quadricalcarifera alleni sp.
n.
Taxonomic note. This and the next species belong to a section of the genus with the
valve of the male genitalia without a terminal spur and with the uncus very
reduced (as two setose lobes), in contrast to the heavy, single, central gnathal
process. This subspecies differs from the typical race slightly in the shape of
the valve, the aedeagus is curved apically rather than straight.
Geographical range.
Taiwan, S. China, Sumatra, Borneo.
Habitat preference. The species has only been taken in upper montane
forest in Brunei, at 1670 m on Bukit Pagon and at 1618 m on Bukit Retak. Records
in Holloway (1976) refer to the next species.
Biology. Little is known of the biology of the numerous Sundanian Quadricalcarifera
species, though Japanese species have been reared from various Fagaceae and
from Styrax in the Styracaceae (Sugi & Nakatomi 1969).
