Neocloeon triangulifer adult

“Triangle small minnow mayfly”

Figures 26 (lateral), 27 (dorsal, ventral)

Plates 16 (lateral), 17 (dorsal, ventral)

DESCRIPTION: H-DCT, H-VCT, T n -DLT, A n - DLT, and several T n -FM compressed laterally along some sections; since subimago maintains these as broad tracheal lumena, this is likely a preservation artifact in the adult.

BODY: Single air sac, coopted from alimentary canal, extending from head capsule to end of 7th abdominal segment (see fig. 21).

HEAD: As above, but with H-DOc extending from trachea leading to H-PO.

THORAX: T1-DVi from H-VCT.
