Genus
Aphiura
Schmitz, 1939
Type
species.
Aphiura breviceps
Schmitz, 1939
.
The
type
species was described from
two males
from
New Zealand
.
Borgmeier
(1963) described a further species from
Australia
(
NSW
) based on a series of a males and a putative female of the same species.
He
subsequently described another female as belonging to this species and added a further species from
Australia
(
NSW
) (Borgmeier, 1967a). I now formally name the misidentified female, describe five new species from
Tasmania
and a new species from
Western Australia
, and provide a key to the known species of this genus
.
This genus is traditionally assigned to the tribe
Beckerinini
(e.g. Borgmeier, 1967a, 1968) on the basis of the supra-antennal (
SA
) bristles being reclinate. Furthermore,
Aphiura
is supposedly lacking the pre-ocellar or antial bristles, to give a frontal bristles formula of 2 SAs plus 4-2-4 bristles (Borgmeier, 1967a). However, below the ‘SAs’ there are two to four hairs that are proclinate, in contrast to the rest of the frontal hairs. I suggest, therefore, that the formula is not atypical, but is the normal 4-4-4 plus two to four
SA
bristles, the latter, however, being atypically greatly reduced. This simpler interpretation supports the contention (Disney, 1994b) that
Aphiura
does not belong to the
Beckerinini
. I therefore herewith formally transfer the genus to the
Metopinini
. Furthermore, the situation in
Paraphiura
(see below) suggests that the precise inclination of the
SA
bristles is not of tribal significance and that the
Beckerinini
, as presently conceived, cannot be characterized.
