Type material.

Holotype, ♀ (SCAU): CHINA: Hainan, Mt. Bawangling, 7.vii.2006, Jing-xian Liu, No. 200800170.

Diagnosis.

Head transverse in dorsal view and elliptical in lateral view (Figs 165, 166); vertex coarsely irregularly rugose (Fig. 165); frons largely yellowish, rugulose or weakly striate (Fig. 167); pronotum flat, largely rugulose, dark brown and with some orange brown parts (Figs 159, 160); scutellum medially distinctly convex and red brown; propodeum largely matt and superficially granulate, without foveolae, only posterior third foveolate-rugose (Fig. 161); pterostigma short, comparatively wide and apically obtuse (Fig. 158); both large teeth on hind femur whitish (Fig. 162); third metasomal tergite with two large ivory patches (Fig. 163); ovipositor sheath 0.7 times as long as body and with brownish subapical band 0.6 times as long as blackish apical part (Fig. 164).

Description.

Holotype, female, length of body 6.0 mm, of fore wing 3.5 mm, and of ovipositor sheath 4.0 mm.

Head. Flagellum with 23 flagellomeres; length of first flagellomere much shorter than scape and pedicel combined, 3.8 times its maximum width, and 0.8 times as second flagellomere; frons finely, transversely sculptured (Fig. 167); coronal area rugose and with acute coronal teeth; vertex with 3 transverse, curved carinae, anterior one strong and arcuate, two posterior one coarse, followed by coarsely irregularly striate-rugose, slightly convex area (Fig. 165); temple largely smooth and shiny, narrowed ventrally and behind eye (Fig. 166), head transverse in dorsal view.

Mesosoma. Neck (Figs 159, 160) elongate and moderately robust, anteriorly distinctly emarginate; neck and middle pronotum at same level dorsally, both coriaceous and sculptured, somewhat microreticulate; pronotal fold absent; posterior pronotum weakly striate, laterally slightly convex; pronotum laterally striate (Fig. 160); propleuron narrow and setose; prosternum largely smooth, anteriorly transversely striate; mesoscutum medially with a distinct transverse sinuate carina, area in front of it microreticulate, area behind foveolate-rugose; scutellum and axillae longitudinally striate; scutellum centrally distinctly convex, apical margin with some punctures (Fig. 161); mesopleuron anteriorly setose, dorsally smooth and ventrally largely striate; propodeum (Fig. 161) anterior 0.6 striate and largely microreticulate, laterally with several shallow foveolae laterally, propodeum posteriorly foveolate-rugose, some foveolae coalescent, inside surface coarsely coriaceous; metapleuron slightly convex and similarly sculptured as propodeum.

Wings. Fore wing (Fig. 158): hyaline; vein 2-CU1 0.1 times as long as vein cu-a; pterostigma wide and short, obtuse and rounded apically, 2.6 times as long as vein r and 5.2 times as its maximum width; vein r ends 0.3 times length of pterostigma behind level of apex of pterostigma; vein SR1 2.6 times as long as vein r; vein SR1 and vein r obtusely angled, vein SR1 elongate towards vein margin and ending near before reaching vein margin.

Legs. Hind coxa transversely striate, striations more regular posteriorly, outer side medially slightly depressed and flattened; hind femur (Fig. 162) finely transversely striate, dorsally sparsely punctuate, with two large acute ventral teeth and some denticles in between, each denticle bearing one short seta; hind tibia coriaceous and microreticulate, 1.3 times as long as hind femur, coarsely micro-areolate, basal narrowed part 1.1 times as long as widened part, inner side of widened part basally steeply depressed and followed by convex area, hind tibia apically densely setose; hind basitarsus robust, its ventral length 3.6 times its maximum width, ventrally densely setose.

Metasoma. First tergite transversely coarsely striate, basally more rugose, subapex much wider than basal part; first tergite 7.6 times as long as its maximum width, 2.3 times second tergite and 0.8 times as long as remainder of metasoma; second tergite subconical, basal part rugose, remainder together with rest of tergites largely smooth; pygidial area setose, laterally shallowly impressed, medially distinctly convex and lamelliform apically, pygidial impression widely reversed V-shaped (Fig. 163); length of ovipositor sheath 0.7 times as long as body length, length of subapical brownish band nearly 0.6 times length of blackish apex (Fig. 164).

Colour. Body mainly black or dark brown; malar space ivory; frons largely vivid yellow; vertex, pronotum, third tergite with yellow spots or patches; coronal teeth, basal 0.7 of scutellum, posterior 0.3 of propodeum and metapleuron, large part of first tergite and hind femur (except ventral teeth) red brown or reddish; middle and hind basitarsi and large teeth of hind femur whitish; ovipositor sheath largely brownish and with ivory subapex.

Male. Unknown.

Distribution.

China (Hainan).

Etymology.

From “macula” (Latin for patch) and “ferus” (Latin for carrying) because of the two pale patches of the third metasomal tergite.

Notes.

This species is similar to Foenatopus menglongensis , but Foenatopus maculiferus has the two pale patches of the third metasomal tergite (absent in Foenatopus menglongensis ), the scutellum convex medially (flat in Foenatopus menglongensis ), the propodeum rather matt (shiny in Foenatopus menglongensis ) and the hind femur comparatively slender (comparatively swollen in Foenatopus menglongensis ).
