Ohenri Fernandez-Triana gen. n.

Type species.

Ohenri gouletorum Fernandez-Triana & Boudreault, here designated.

Diagnostic description.

Antenna with placodes irregularly distributed in three and up to four rows. Pronotum enlarged dorsally, its median length (on a dorsal view) very large, much larger than width of flagellomeres, and clearly larger than propodeum in most Microgastrinae genera (Fig. 32F ). Pronotum with dorsal and ventral sulci. Most of mesosoma sculptured with relatively deep, close punctures. Propodeum with median carina clearly defined on anterior 0.6, and then obscured by partially defined areola on posterior 0.4 (Figs 32E, F ). Fore wing without areolet. Hind wing with vannal lobe concave and without setae. Tarsal claws pectinate, with two large teeth near base of claw. T1 and T2 dull, T3+ mostly smooth (Fig. 32E ). Hypopygium uniformly sclerotized and sharply pointed apically (Fig. 32A ). Ovipositor sheaths uniformly setose and clearly shorter than metatibia length. Ovipositor with four subapical serrate teeth on lower (first) valvulae (Fig. 32D ).

Putative autapomorphies and potentially related genera.

Pronotum enlarged dorsally (shared with Qrocodiledundee , see below under description of that genus). The subapical teeth in the lower valvulae of ovipositor are very unusual in Microgastrinae (although not unique to Ohenri ), as are the antennal placodes irregularly distributed, the large teeth on tarsal claws, and the propodeum with a combination of a median carina and partially defined areola. The relationships of Ohenri with other genera of Microgastrinae are not clear at present, although some morphological features are related to Sathon s. str. and two new genera, Carlmuesebeckius and Qrocodiledundee , also described in this paper.

Biology.

Host unknown.

Distribution.

The only known species is found in the Afrotropical region (Nigeria).

Molecular data.

No molecular data available.

Etymology.

The genus name refers to and honors the Canadian braconid expert Henri Goulet, a dear friend, colleague and mentor for many years. The letter “O” added to the beginning of the genus name also plays with words, to loosely refer to the chocolate brand "Oh Henry!" -an indirect mention to Henri’s fondness for sweet treats. The gender of the genus is neuter.

Species.

Only one species is known.
