Revised diagnosis.
In having the parameres branched,
Acritoptila planichela
resembles
Acritoptila forficata
, sp. n. however in
Acritoptila forficata
the parameres are more slender and the mesal branch is the shorter, finer branch and closely associated with the lateral branch whereas in
Acritoptila planichela
the lateral branch is shorter and finer than the lateral branch, and
Acritoptila planichela
lacks the pronounced lateral lobes on abdominal segment IX seen in
Acritoptila forficata
sp. n.
Acritoptila planichela
shares with
Acritoptila ouenghica
and
Acritoptila macrospina
sp. n. the feature of curiously modified knob-like setae on the fused, non-sclerotized gonopods, but neither of those species has branched parameres. Male antennae damaged in only specimens at hand; forewing length, 2.1 mm (n = 1).

Remarks.
Only a single specimen was collected despite the extensive field work. Thus, with the 3 identified by
Kelley (1989)
, 4 specimens are now known, all from the southern province.
Material examined.
Holotype male: New Caledonia, mountain stream up Boulari River, (BPBM); 1 male (on slide), Province Sud, Monts Kwa Ne Mwa, on road between Noumea and
Yate
