Variation.
Adult male of
4.6 mm
(AM P.92526) with well developed lobes on the gnathopod 2 basis, which are not present on smaller male and female specimens of
4 mm
and
4.2 mm
body length (AM P.92527 and AM P.92528).
Remarks.
Specimens from the Northern Territory have only three robust setae on each telsonic lobe, for both juveniles and adults, in contrast to the
type
material from
Timor-Leste
, which has four robust setae. With only one seta difference the, material is attributed to
Q. metinaro
.
Quadrimaera mirandelle
Appadoo& Myers, 2002
from
Mauritius
has a similar gnathopod 2 propodus palm to
Q. metinaro
, and the telson has 5 robust setae. With
Q. metinaro
from Northern Territory presenting an intermediate telson setal number the possibility that these latter species is a junior synonym was considered, but the gnathopod 2 dactylus is more medially broad in
Q. mirandelle
.
