Diagnosis

Hind wing very slender (length: width ratio about 6.0); Ax1 and Ax2 nearly perpendicular to ScP in both wings; arculus very oblique and curved; only one row of cells in area between IR2 and RP3 / 4 and in area between MA and MP, at least in the basal two-thirds of their course; straight gaff (basal part of CuA) very long, correlated with the width of basal part of area between MP and CuA three times as wide as that of basal part of postdiscoidal area in forewing (2.5 times in hind wing); CuAa short in both pairs of wings ending on posterior wing margin about midway between arculus and nodus; subdiscoidal cell free of crossveins; AA separated into AA1 and AA2 after CuP-crossing; posterior margin of hind wing making a strong “hook” in anal area.

Etymology

Named after Latin prefix angust - (meaning narrow) to indicate the slender hind wing of the new specimen; feminine in gender.
