Ptychoderes jekeli was recently described and illustrated by Mermudes and Napp (2004). Here it is added:

Female paratype. Ovipositor (apex exposed) with a toothed plate similar to that of P. crustatus .

Male. Unknown.

Remarks

P. jekeli belongs to the P. crustatus + group, being the sister group of P. brevis by the synapomorphies mentioned under this species (20 5, 36 2). It differs from P. brevis by the dorsal vestiture with dark­green scales plus the autapomorphies: 1) mentum transversely carinated; 2) segments of antennal club robust and elongate; 3) prosternum transversely raised and 4) glabrous area of mesofemora with two coarse punctures. In P. brevis , the dorsal vestiture has olivaceous­green scales, the mentum not transversely carinated, the segments of antennal club short and less thickened, the prosternum not raised and the glabrous area of mesofemora finely, densely punctate.

With regard to the greenish dorsal vestiture, P. jekeli looks like P. jordani and P. viridanus , species related, respectively, to the groups P. obsoletus + and P. antiquus +.
