( Figs. 1, 18, 151)

Description. Forewing length: males 3.9–5.1 mm (mean = 4.2, n= 10), females about 5.2 mm. Colour stramineous, margins of facial carinae light brown. Forewings colourless. Facial carinae clearly separated. Male anal segment with prominent lateral processes. Genital styles widening towards the end which is slightly concave; the dorsal apical corner slightly produced; proximal dorsal process short, well separated from distal dorsal process, which has a nearly quadratic base and a club-shaped apical part; at the inside near the base with a finger-like process bearing bristles at the tip. Aedeagus with apical portion flat, its apex truncate, rarely slightly pointed; the left margin bladelike; right side shorter and broader; in some specimens the dorsal side with humps.

Etymology. The species name is a Latin adjective (peregrinus, -a, -um = foreign).

Diagnosis. Dichotropis peregrina is indistinguishable externally from D. brevis sp. nov., D. straatmani sp. nov., and D. nivea sp. nov., all three also found in New Guinea. The male genitalia are most similar to those of D. straatmani , but the anal segment has prominent lateral processes, the bases of the dorsal processes of the genital styles are wider apart, and the aedeagus lacks a narrow, straight terminal lobe.
