Lin, Meiying, Weigel, Andreas & Ge, Siqin, 2022, A new species of Minagenia Banks, 1934 (Hymenoptera: Pompilidae) from China, with a key to the Oriental species, Zoological Systematics 47 (4), pp. 341-344 : 341-343

Minagenia bannensis He & Ma , sp. nov. ( Fig. 1 )

Diagnosis. The new species clearly differs from M. fulvifemoralis Ji & Ma and other congeners by the combination of following characters: mandible bidentate apically, inner tooth blunt and smooth apically; frontal line shiny and long, reaching anteriorocellus; M of fore wing not reaching apical margin; SMC2 small and length of SMC2: SMC3 = 1: 2. It is similar to M. fulvifemoralis , which is characteristic by: mandible bidentate apically, inner tooth pointed apically; frontal line shiny, reaching median frons; M of fore wing reaching apical margin; SMC2 normal and length of SMC2: SMC3 = 1: 1.

Description. Female ( Fig. 1 ). Body length 9.5–11.0mm.

Coloration ( Figs 1A–B ). Integument black except: mandible apically, hind femur medially, all tarsus apically and ventrally, gaster posterior margin reddish-brown; labrum except medially dark brown, maxillary palpus partly yellowish; labial palpus brown except ventrally yellowish, maxillary palpus 1–2 brown and other yellowish with erect, whitish setae, labrum and mid leg brown; scape ventrally with shiny line and short stripe; hind tibia brown-reddish to brown; hind tarsus and fore coxa apically yellowish; fore wing subhyaline (sometimes with unbounded marking basally), with a stripe on marginal cell, SMC2 and SMC3 largely, posterior half of discal cell 2, SMC4 and discal cell 3 basally; veins light brown; pubescence dense, short, appressed and golden, throughout entirely body; propodeal inclined slope with appressed, dense, whitish pubescence posteriorly; mesopleuron posterior margin with somewhat dense pubescence; mandible with appressed, silvery pubescence basally.

Head. Clypeus slightly elevated, anterior margin nearly truncate medially, posterior margin and frontoclypeal suture inconspicuously concave and with long, slivery setae; labrum exposed, anterior border slightly convex and angulate in lateral view; mandible bidentate and inner teeth blunt apically ( Fig. 1D ); frontal line shiny, reaching anteriorocellus; area between antennal sockets with shallow depression; vertex flat ( Fig. 1E ); ratio width of frons and eye in frontal view = 50: 38 (Fig. 2F); gena very narrow and almost invisible in lateral view, ratio length and width medially = 14: 1 ( Fig. 1F ); ocelli in right triangle, ocellar area slightly elevated, anterior ocellus larger than posterior ones ( Fig. 1E ); inner orbits almost parallel; scape depressed basally in ventral view ( Fig. 1D ); antenna slender, A3 five times longer its width; ratio POD: OOD: Od: OCD = 6: 8: 5: 10; HW: HL = 13: 15; ratio length from A1 to A12 = 8: 3: 12: 10: 10: 8: 8: 7: 7: 7: 6: 6.

Mesosoma. Posterior margin of pronotum gently arched; mesoscutum with a pair longitudinal stripes and angulate anteriorly, parapsidal line distinct and not reaching pronotum ( Fig. 1H ); metanotum length nearly equal to postnotum medially ( Fig. 1G ); mesoscutum posterior margin, scutellum anterior and posterior margins conspicuously concave ( Fig. 1H ); mesonotum medially elevated; mesopleuron flat, inconspicuously convex posteriorly; metapleuron strongly convex posteriorly; postnotum longitudinally impressed medially, and with inconspicuous, sparse, transversal striations, anterior and posterior borders almost parallel medially; propodeum elevated, densely punctate and with longitudinal concave medially, propodeal spiracle long, slightly depressed ( Fig. 1G ); 2rs-m received by 1m-cu to obtuse triangle; 3rs-m nearly straight and slightly curved outwards, M of fore wing not reaching apical margin and Cu of fore wing reaching apical margin; 2m-cu received by middle of SMC3; hind wing cu-a joins M+CuA juncture of M with CuA; SMC2 small and ratio length of SMC2 and SMC3 = 1: 2 ( Fig. 1C ); ratio fore, mid and hind femur/tibia = 9/7, 9/10, 15/15; all tarsal claws symmetric, bifid, inner teeth obliquely truncate ( Fig. 1I ).

Metasoma. Not petiolate, S2 without transverse groove; S6 strongly compressed, with erect long setae; S3–5 like a rectangle in lateral view ( Fig. 1A ).

Male. Unknown.
