Acritoptila ouenghica Wells Fig. 20

Acritoptila ouenghica Wells (1995: 235).

Revised diagnosis.

Acritoptila ouenghica groups with Acritoptila planichela and Acritoptila macrospina sp. n. in having, in the male genitalia, curiously modified setae on the fused gonopods, described as “tab-like” by Wells (1995) but in the two other species more knob-like. Unlike other New Caledonian congeners, Acritoptila ouenghica lacks the free parameres, the parameres instead appear to be fused laterally as broad sclerotized margins on tergite X, although in cleared specimens these clearly arise from stout apodemes. Male antennae each with 30-33 flagellomeres; forewing length 1.9-2.2 mm (n = 8).

Remarks.

Very few specimens of Acritoptila ouenghica were taken in all the recent collecting - one specimen from the south and several from the north (Fig. 35) - and no females have been associated.
