Triphleba ehmseni sp. n.

( Figs 128–137 ).

Material examined. Holotype male, DENMARK, DK SJ, Buntje Ballum , 17.v–8.vi.2014, Esben Bøggild (UCMZ-8-59). Description. Male. Head as Fig. 128 . Postpedicel of antenna as Fig. 129 . Thorax as Fig. 130 , the anterior scutellars being small hairs. Abdominal tergites brown, with moderate hairs that are longer laterally on T2 and longest at rear of T6. Venter pale gray and lacking hairs. Hypopygium as Figs 131–133 . Front leg as Fig. 134 . Middle leg as Fig. 135 . Hind femur and tibia as Fig. 136 . Wing ( Fig. 137 ) 1.5–1.6 mm long. Costal index 0.53. Costal ratios 3.6: 1.8: 1. With a single axillary bristle ( Fig. 130 ). Haltere dark ( Fig. 130 ).

Recognition. In the keys to Palaearctic species (Shcmitz, 1943) it runs to couplet 69, lead 2 to T. hentrichi Schmitz (1935) , but is immediately distinguished by its narrower paler palps with several robust bristles in addition to the longer terminal bristle. Those of T. hentrichi are fewer and much less robust. The hypopygia are similar but the tip of the left epandrial process is less symmetric in T. hentrichi .

Etymology. Named after Erhardt & Kirsten Ehmsen in whose premises the holotype was trapped.
