Diplacodes deminuta Lieftinck, 1969
Little Percher

Synonyms:

  • scientific: D. okavangoensis Pinhey, 1976

Type locality: Samfya, Zambia

Diagnosis

Male is similar to D. pumila by (a) small size, Hw 15-21 mm; (b) becoming largely black with maturity, sometimes partly with pale grey pruinosity; (c) patch at Hw base at most deep amber; (d) Pt only about 2 mm. However, differs by (1) relatively shorter hook of hamule; (2) tip of epiproct usually closer to tip than ventral angle of cerci. Also, when body is not yet entirely black (3) mesepisternum yellowish, like sides of thorax; (4) S8 at most with small or indistinct pale spot, S9-10 all black. When body is all black (5) face often laterally or frontally yellow, rather than all black; (6) Pt whitish rather than brown; (7) only tip of epiproct and tips of cerci usually dark, rather than the entire epiproct as well as underside of the cerci.
