Diagnosis
Occipital carina widened medio-dorsally, with short carinae (Fig. 40); outer side of supra-antennal elevations subvertical and elevations about 0.7 times as long as scapus (Figs 40, 43); head dorsally coarsely reticulate-punctate (Fig. 40); apical half of supra-antennal elevations yellowish brown (Fig. 40); tyloids of male antenna elliptical and short (Fig. 51); basal half of metasoma largely smooth, apical half mainly punctate (Fig. 46); metasoma largely black with narrow orange-brown apical band at apex of all tergites (Figs 46, 47); first tergite about 0.7 times as long as its apical width (Fig. 46); third sternite about 0.2 times as long as second sternite (Fig. 48).
Description
Holotype, female, length of body 6.6 mm (of fore wing 5.8 mm).
Head. Antenna with 23 segments; frons coarsely reticulate-punctate (Fig. 39), with rather long setae; vertex coarsely reticulate-punctate behind posterior ocellus, spaced punctate (interspaces much wider than width of punctures) posteriorly (Fig. 40); temple largely smooth with sparse fine punctures (Fig. 43); head gradually narrowed behind eyes, eye in dorsal view 1.5 times as long as temple (Fig. 40); occipital carina strongly widened and lamelliform medio-dorsally, with many short carinae; supra-antennal elevations strongly enlarged (about 0.7 times as long as scapus), outer side subvertical and largely smooth except for sparse punctures; clypeus slightly concave and thick medio-ventrally.
Mesosoma. Length of mesosoma 1.6 times its height (Fig. 45); mesopleuron antero-dorsally irregularly rugose, dorso-posteriorly smooth and shiny and antero-ventrally obliquely rugose; notauli wide, deep and largely crenulate; middle lobe of mesoscutum irregularly rugose, lateral lobes mainly finely rugose (Fig. 44); scutellar sulcus complete, very wide and crenulate; scutellum densely reticulate-rugose, convex posteriorly and flattened anteriorly and medially; metanotum medially strongly lobe-shaped protruding and largely rugose (Fig. 44); propodeum coarsely rugose (Fig. 44); posterior propodeal carina thick lamelliform (foramen about twice as wide as high medially).
Wings. Fore wing: length of vein 1-M 1.6 times as long as vein 1-SR (Fig. 42).
Metasoma. First tergite 0.7 times as long as apically wide, smooth and with distinct elliptical depression medially (Fig. 46); second tergite largely smooth with sparse fine punctures posteriorly, other tergites superficial coriaceous anteriorly, densely finely punctate posteriorly (Fig. 46); sternites densely finely punctate; second sternite weakly curved in lateral view; third sternite about 0.1 times as long as second sternite (Fig. 48); hypopygium triangular in ventral view (Fig. 48).
Colour. Black; inner orbita narrowly orange-brown; apical half of supra-antennal elevations yellowish brown, clypeus with a narrow transverse orange-brown patch; minute patch of outer orbita, vertex posteriorly, occipital carina medially and mandible largely yellowish brown (Figs 39, 40, 43); mesosoma laterally black except for brown dorsal rim of pronotal side; middle lobe of mesoscutum with pair of narrow brown patches anteriorly; axilla with medium-sized brown patch; metanotum with pair of small lateral yellowish brown patches; metasoma dorsally black, with narrow orange-brown apical band at apex of all tergites and first two sternites (Figs 46, 47, 48); palpi dark brown; antenna brown, becoming darker apically; legs dark brown to black; pterostigma brown, remainder of wing membrane subhyaline.
Variation. Length of body 6.6–9.8 mm, of fore wing 5.8–8.7 mm; propodeum with pair of small brown spots; vertex coarsely reticulate-punctate; temple rugulose-punctate; second tergite with dense fine punctures posteriorly; length of vein 1-M of fore wing 1.5–1.6 times as long as vein 1-SR.
Male. Length of body 8.3–9.1 mm, of fore wing 6.8–7.8 mm; antenna with 23 segments, tyloids elliptical, 0.25 times as long as segment on 11th–13th segments and nearly circular on 14th and 15th segments; in general males are darker than females: vertex and outer orbita entirely black; mesosoma with or without brown patches; first and third tergites sometimes without narrow orange-brown apical band; genitalia extruded (Fig. 52).
Biology
Collected in June–August.
Distribution
China (Sichuan).
Etymology
Named after the elliptical tyloids of the male antenna and “fera” (Latin suffix for “carry, have”).
