DISTRIBUTION: NW Vietnam: Son La. BIOLOGY: Unknown. DIAGNOSIS: Antenna with 32 segments; antennal segments 11–14 cream white; maxillary palp short, 1.1 × length of head; in dorsal view width of head 1.6 × its median length; height of eye 2.4 × temple; frontal protuberance acute, slightly higher than lateral frontal carina. Mesosoma 2.3 × longer than high; notauli crenulated, fused posteriorly with transversely rugose area; propodeum with basal carina and areola; areola and propodeum medially areolate-rugulose, coriaceous basally and apically. Length of forewing 3.3 × its maximum width; vein 3-SR slightly longer vein r; vein 2-M 2.6 × 3-SR; hind wing vein 1-M 0.7 × vein 1r-m; vein 2-SC+R transverse; hind wing with 3 hamuli. Foretarsus 1.4 × as long as foretibia; hind femur only with ventral serrations; length of hind femur (without serrations) 3.7 × its maximum width; outer side of hind coxa almost smooth, with scattered fine punctures; hind femur rugose-punctate. First metasomal tergite widened from base to apex, length 1.1 × its apical width (fig. 34); first tergite with dorsal carinae in basal 0.9 of tergite; median length of second tergite 0.55 × as long as its basal width; second tergite slightly longer than third tergite; first tergite nearly smooth basally and laterally, foveate-rugulose medioapically; second suture distinct; second tergite punctate laterally and foveate-punctate medially; third tergite smooth. NOTES: W. coffeana, sp. nov., runs out in couplet 3 of the key by Yan et al. (2017), because of the following characters: frontal protuberance near antennal sockets blunt dorsally; scapus densely setose ventrally; ventral margin of hind femur without tooth-shaped protuberance and only with serrations; first metasomal tergite pale yellow and smaller (body length 4.3 mm).

Mesosoma: Mesosoma 2.3 × longer than high (80:35) (fig. 32); pronotal side largely carinate-rugose medially, largely rugose dorsally and ventrally; mesopleuron slightly depressed medially, largely smooth (fig. 32); metapleuron coarsely rugose; lobes of mesoscutum largely smooth; notauli crenulated, fused posteriorly with transversely rugose area; scutellar sulcus deep, curved, with one carina, 0.55 × as long as scutellum (5:9) (fig. 31); scutellum coriaceous; propodeum with basal carina and areola; areola and propodeum medially areolate-rugulose, coriaceous basally and apically (fig. 33). Wings. Forewing: length of forewing 3.3 × its maximum width (107:32); pterostigma 3.7 × longer than wide (26:7); vein 3-SR slightly longer than vein r, r:2-SR:3-SR:SR1:r-m = 5:9:6:42:7; vein 1-CU1 nearly quadrate (fig. 35); cu-a:2-CU1 = 7:14;, vein 2-M 2.6 × 3-SR (13:5) (fig. 35);; hind wing vein 1-M 0.7 × vein 1r-m (6:9); vein 2-SC+R transverse (fig. 37); hind wing with 3 hamuli. Legs: Foretarsus 1.4 × as long as foretibia (19:14); hind femur with ventral serrations, without ventral tooth-shaped protuberance (fig. 36); length of hind femur (without serrations), tibia, and basitarsus 3.7 (52:14), 7.7 (69:9), and 5.5 × (22:4) as long as their maximum width, respectively; hind basitarsus 0.3 × as long as hind tibia (22:69), and 0.6 × as long as second–fifth hind tarsal segments (22:36); fourth hind tarsal segment 0.45 × as long as telotarsus (5:11); outer side of hind coxa almost smooth, with scattered fine punctures; hind femur rugose-punctate (fig. 36). Metasoma: Metasoma 0.9 × as long as head and mesosoma combined (48:55); first metasomal tergite widened from base to apex, 1.1 × longer than its apical width (31:28) (fig. 34); first tergite with long dorsal carinae in basal 0.9 of tergite (27:31); median length of second tergite 0.55 × its basal width (16:29), and slightly longer third tergite (16:15); first tergite nearly smooth basally and laterally, foveate-rugulose medioapically; second suture distinct; second tergite punctate laterally and foveate-punctate medially; third tergite smooth; ovipositor sheath about as long as forewing (35:36). Color: Body dark brown, antenna brown, yellowish brown basally, with 11th–14th antennal segments cream white; palpi pale yellow; fore- and middle legs yellow; hind coxa, trochanter and trochantellus yellow; hind femur yellow basally and brown apically; hind tibia brown, but whitish yellow basally; hind tarsus pale yellow, but basitarsus basally and telotarsus brown; pterostigma and wing veins brownish yellow; wing membrane hyaline; first metasomal pale yellow; second–sixth tergites brown; ovipositor sheath brown. Male: Unknown. ETYMOLOGY: Named after the plant genus Coffea Linnaeus, because the new species was collected in a Malaise trap set in a coffee orchard.
