Xyalaspis
is a new record for
New Zealand
, which likely represents an adventive species. The identification of
Xyalaspis
is based on the scutellar spine (
Fergusson 1985
). A species level determination has not been made, but it is not
X. victoriensis
(which has a very elongate scutellar spine), the only
Xyalaspis
in
Australia
(
New 1979
). The apex of the scutellum in both
Anacharis
and
Xyalaspis
is very prominent, however, the two can be separated as
Anacharis
has an elongate petiole and an internally carinated transverse groove in the mesopleuron.
Xyalaspis
is uncommonly collected (only
15 specimens
in the NZAC) but is widespread. North Island: AK, HB, TO. South Island: MC, NN, SL. The first record is from 1959, and a number of records are associated with orchards (from HB, MC, and NN). Two NZAC records indicate it is a parasitoid of
Neuroptera
.
