Phyllomacromia paula (Karsch, 1892)
Greater Double-spined Cruiser

Synonyms:

  • scientific: P. paludis (Sjöstedt, 1900)

Type locality: Buea, Cameroon

Diagnosis

Male is similar to P. bispina by (a) frons broadly dark, without isolated, contrasting marking; (b) thorax with 2-3 pale stripes on each side: usually 1 antehumeral and 2 laterals, but one of these may be reduced; (c) hamule stout; (d) dorsum of S10 with peak bearing 1-2 cones; (e) peak of S10 bearing 2 cones clearly separated at their base (best seen in caudal view); (f) cerci and (tip of) genital lobe black. However, differs by (1) larger size, Hw 40-45 mm; (2) labium uniformly brown; (3) hamule with evenly rounded border, narrowing gradually to large hook.

Habitat description

Streams, but possibly also rivers, mostly shaded but sometimes in open areas in forest. Often with a gravelly and/or sandy bottom and probably blackwater and coarse detritus. From 0 to 1000 m above sea level, but possibly much higher up.
