Type material

Holotype, + (ZJUH) “[China:] Fujian, Shaxian County, 14.X.1980”. Paratypes: 1 + (IZCAS) “[China:] Yunnan, Xishuangbanna, Damenglong, 650 m, 11.IV.1958, Shu-yong Wang, IOZ(E)1495238”; 1 + (IZCAS) “[China:] Yunnan, Xishuangbanna, 850 m, 22.VIII.1958, Le-yi Zheng, IOZ(E)1495239”; 1 + (CASSF) “China, S. Kiangsi, Sunwu, 12.vii.1936”, “L. Gressitt collector”, “Lycogaster celebesiensis (Szepligeti, 1902). Det. Carmean, 1993”.

Diagnosis

Antenna of female distinctly widened medially (Fig. 124); outer side of supra-antennal elevations strongly oblique and elevations 0.2 times as long as scapus (Fig. 121); vertex comparatively flat in lateral view (Fig. 122); area between ocelli and eye distinctly punctate (Fig. 121); mandible and mesosoma entirely black (Figs 120, 123); lateral lobes of mesoscutum sparsely punctate laterally (Fig. 123); medial third of fore wing largely dark brown (Fig. 125); vein m-cu of fore wing subinterstitial (Fig. 125); second metasomal sternite largely yellow posteriorly (Fig. 129); second sternite with pair of comparatively far separated small triangular teeth sublaterally and in between sternite convexly protruding medio-posteriorly (Fig. 129); second tergite punctate and moderately shiny (Fig. 127).

Description

Holotype, female, length of body 13.4 mm (of fore wing 10.1 mm).
Head. Antenna with 23 segments, segments after third segment distinctly widened and after 14th segments becoming gradually slenderer (Fig. 124); frons coarsely and rather densely punctate and vertex spaced punctate (interspaces often much wider than width of punctures) and shiny (Figs 120, 121), with short greyish setae; head subparallel-sided behind eyes, distinctly narrowed posteriorly and 1.3 times wider than mesoscutum (Fig. 121); dorsal length of eye 0.9 times length of temple (Fig. 121); temple smooth, shiny and with medium-sized whitish setae; occipital carina narrow lamelliform medio-dorsally and without crenula; supra-antennal elevations hardly developed as a thin rim and smooth; clypeus weakly emarginate and comparatively thin medio-ventrally.
Mesosoma. Length of mesosoma 1.3 times its height (Fig. 126); mesopleuron below transverse mesopleural groove densely rugose anteriorly and spaced punctate and weakly shiny posteriorly, above groove similar but rugae finer posteriorly denser punctate; transverse mesopleural groove narrow, deep and moderately crenulate; notauli narrow anteriorly, widened posteriorly and coarsely crenulate; middle lobe of mesoscutum coarsely vermiculate rugose and weakly shiny (Fig. 126), its lateral lobes mainly coarsely punctate and medially with smooth interspaces; scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum largely smooth (except some punctures), distinctly shiny, rather flat and anteriorly near level of mesoscutum; metanotum flat, shiny and smooth medially (Fig. 126); propodeum largely densely finely rugose and carina of foramen thick and arched (Fig. 126); foramen medially 0.6 times higher than wide basally.
Wings. Fore wing: length of vein 1-M 2.3 times as long as vein 1-SR (Fig. 125).
Metasoma. First tergite 0.4 times as long as apically wide, gradually narrowed basally, flattened medially and weakly convex apically; second–fifth tergites largely densely coarsely punctate and rather moderately shiny; second sternite similarly sculptured as tergite, its medio-apical protuberance lamelliform and convex medio-apically (Fig. 129) and with pair of triangular submedial teeth, third sternite only with distinct ledge (Fig. 129); hypopygium truncate apically.
Colour. Black (including mandible); palpi, fore tibia and tarsus, tegulae, pterostigma and veins dark brown; apex of middle trochantellus, hind trochanter and trochantellus, and narrowly base of hind femur ivory; pair of large lateral patches on second and third tergites and apically on second sternite yellow; fore wing largely dark brown but paler subbasally (Fig. 125).
Variation. Length of body 11.5–13.1 mm, of fore wing 8.9–10.0 mm; length of vein 1-M 1.9–2.1 times as long as vein 1-SR; outer side of fore tibia ivory; vein m-cu of fore wing subinterstitial or postfurcal by 0.2 times length of vein m-cu; third tergite with a pair of small to medium-sized yellow or ivory patches laterally.
Male. Unknown.

Biology

Unknown. Collected in April, July, August and October at 650–850 m.

Distribution

China (Fujian, Jiangxi, Yunnan).

Etymology

Name derived from “flavus” (Latin for “yellow) and “niger” (Latin for “black”) because of the yellow-black pattern of the second sternite.

Notes

This species was confused with Lycogaster celebesiensis (Szepligeti) by Carmean and Kimsey (1998)[1]. Lycogaster flavonigrata differs as follows: medial third of fore wing dark brown (largely subhyaline of Lycogaster celebesiensis); area between ocelli and eye distinctly punctate (mainly smooth); mandible and mesosoma entirely black (with yellow patches); protuberance of second metasomal sternite convexly protruding medially or truncate (straight or weakly concave medio-apically).
