Type species: Odynerus margaretellus Rohwer, 1915 , here designated.

DIAGNOSIS. The new genus belongs to the Odynerus group of Odynerini s. str. It can be distinguished from the genus Odynerus by a narrow apical margin of the clypeus ( Figs 2,

5) with acute lateral teeth in both sexes (broad margin in both sexes with rounded teeth in the female in Odynerus , Figs 13, 16, 17 ), the absence of distinct pronotal foveae and the pronotal carina (both present in Odynerus ), sharply impressed notauli and distinct parapsidal lines ( Fig. 4 ) (both absent in Odynerus , Fig. 14 , but present also in Paravespa ), the tegula with a small but evident inner posterior angle where it adjoins the scutum (completely rounded posteriorly in Odynerus , Fig. 15 ), the presence of an epicnemial carina (absent in Odynerus ),

a dense short pilosity of the posterior sterna in the male (absent in Odynerus but present in

Tropidodynerus and some Paragymnomerus ), and a broad, greatly expanded and truncate apex of the male aedeagus (Bohart, 1939: 79, fig. 3) (present also in Paravespa , Fig. 7 ). Furthermore,

males of Odynerus have either a projection on the gena behind the mandible or on the mid coxa (subgenus Spinicoxa , Figs 16, 19 ), or an extraordinarily notched mid femur (subgenus

Odynerus s. str., Fig. 20 ), or a sharp edge of the fore femur beneath (subgenus Monoplomerus ).

Male genitalia of Odynerus ( Fig. 18 ) are also very different from Bohartodynerus gen. n.; the shape of the aedeagus in Gymnomerus ( Fig. 9 ) is rather similar to that in Odynerus ( Fig. 8 ),

while it is also distinctly different in Paragymnomerus ( Fig. 10 ) and Tropidodynerus ( Fig.

11).

DESCRIPTION. Female. Head about 1.2 as wide as long in frontal view; clypeus about

1.2 as wide as long, with shallow apical emargination as wide as distance between antennal foveae, apical teeth acute ( Fig. 2 ). Mandible without notch. Proboscis short, not reaches mid coxae. Maxillar palpi with 6 articles; labial palpi with 4 articles. Vertex longer than upper portion of compound eye in dorsal view; cephalic foveae small and shallow or indistinct,

separated by distance somewhat larger than that between lateral ocelli ( Fig. 3 ). Anterior face of pronotum without distinct foveae; pronotal carina absent; pronotum beneath without acute angle anteriorly. Notauli sharply impressed, running entire length of scutum; parapsidal lines present on distal 2/3 of scutum; scutum evenly punctured ( Fig. 4 ). Tegula small, nearly rounded posteriorly but with evident inner posterior angle where it adjoins scutum; parategula very small. Epicnemial carina present. Scutellum convex; axillary fossa deep. Metanotum rounded posteriorly. Propodeal shelf not developed. Propodeal concavity rather flat, its lateral borders rounded. Propodeal valvula entire. Second submarginal cell of fore wing not petiolate, with acute basal angle. Parastigma shorter than pterostigma. Tergum 1 hardly petiolate, without transverse carina at summit and without apical furrow. All metasomal terga without apical lamellae. Sternum 2 without distinct basomedian longitudinal sulcus. Black wasps with reddish pattern and erect, long, mostly dark pilosity ( Fig. 1 ).

(18 – genitalia, dorsal view; 20 – mid leg beneath). Photos by M.Yu. Proshchalykin.

Male. Resembles female but clypeus with deeper apical emargination and covered with pale appressed setae besides erect dark pilosity ( Fig. 5 ). Gena without projection behind mandible. Antenna with flagellomere 10 much shorter than flagellomere 11; apex of antenna forming hook (Bohart, 1939: 79, fig. 11) or loose coiling. Fore femur beneath without sharp edge. Mid leg with neither projection on coxa nor any unusual structures on femur ( Fig. 6 ).

Sterna 3–6 with dense short pale pilosity. Aedeagus very broad, greatly expanded and truncate apically (Bohart, 1939: 79, fig. 3).

ETYMOLOGY. The new genus-group name is dedicated to Richard M. Bohart (1913–

2007), a famous entomologist, for his significant contributions to the taxonomy and syste-

matics of the American eumenine wasps. The gender is masculine.
