Figures 2 View Figure 2 , 3 View Figure 3
Diagnosis.
Male. Head rectangular and elongate (Fig. 2B View Figure 2 ). Clypeus with median lobe truncate, median carina incomplete, not reaching anterior clypeal margin, and straight in dorsal profile. Eye glabrous (Fig. 2B View Figure 2 ). Notaulus very weakly converging posteriorly, complete and deep (Fig. 2C View Figure 2 ). Propodeum polished (Fig. 2C View Figure 2 ). Pterostigma broad, about 0.4 × as wide as long (Fig. 2F View Figure 2 ). Metatrochanter without spine (Fig. 3G View Figure 3 ). Metafemur with only one acute spine in ventral midline, 0.26 × as long as metafemoral width, touching apical margin of metatrochanter, and with one small, broad and dentate protuberance ventrally, 0.04 × metafemoral width, located on second quarter of metafemur (Fig. 3G View Figure 3 ). Posterior hypopygeal margin strongly incurved, lateral lobe without conical protuberance (Fig. 3E View Figure 3 ). Basivolsella large, 0.6 × as long as gonostipe, basal half about as wide as apical half, basal margin incurved (Fig. 3C, D View Figure 3 ).
Description.
Male holotype. Body length 4.52 mm. Forewing length 3.10 mm. Colors. Head, mesosoma, metasoma, antenna and apex of mandible dark castaneous; palpi, base of mandible, all tibiae and tarsi castaneous; wings subhyaline, fore wing somewhat infuscate medially.
Head. Head (Figs 2B View Figure 2 , 3A View Figure 3 ) rectangular and elongate, 1.2 × as long as wide. Mandible with five apical sharpened teeth, posterior tooth largest, middle three teeth smaller, anterior tooth smallest. Clypeus with median lobe truncate, median carina incomplete, not reaching anterior clypeal margin, and straight in dorsal profile. Eye glabrous, almost touching mandible base at anterior corner. Malar space reduced. Frons weakly coriaceous, almost polished, punctures very sparse and small. WH 0.84 × LH. WF 0.66 × WH. WF 1.63 × HE. OOL 1.44 × WOT. Frontal angle of ocellar triangle obtuse. Anterior ocellus far posterior to supra-ocular line. Temple divergent anterad, corner rounded. Vertex badly outcurved. First four antennomeres in ratio of about 25:12:11:11 (Fig. 2E View Figure 2 ). All flagellomeres distinctly longer than wide, pubescence erect, about 0.48 × as long as flagellomeral width. Maxillary palpus with five palpomeres (Fig. 3A View Figure 3 ). Labial palpus with two palpomeres (Fig. 3A View Figure 3 ). Occipital carina complete. Medioccipito-genal carina complete. Hypostomal carina thick, almost straight, angled medially.
Mesosoma (Figs 2C, D View Figure 2 , 3B View Figure 3 ). Mostly polished and weakly coriaceous. Pronotal flange short, exposing propleuron dorsally. Dorsal pronotal area short, without anterior carina strongly progressively narrowing anterad, lateral surface concave. Notaulus very weakly converging posteriorly, complete, deep, and progressively more evident posteriorly. Parapsidal signum sinuous, absent anteriorly. Mesoscutellum shorter than anteromesoscutum. Mesoscutum-mesoscutellar sulcus deep, arched, sides wider than middle. Metanotum conspicuous, metascutellum wide and short, metanotal trough not trabeculate, metanotal fovea outlined. Metapectal-propodeal disc polished, metapostnotal median carina complete, although weak posteriorly, lateral and transverse posterior carinae complete; propodeal spiracle circular, located on lateral surface of propodeum, ventral to lateral carina. Propodeal declivity transverse sculptured, without median carina. Mesopleuron with mesopleural pit large and well defined. Pleurosternum small, triangular, with vertex directed posterad. Prepectus with epicnemial medial projection complete, posterior prepectal flange thick. Wings (Fig. 2F View Figure 2 ). Forewing with three closed cells (Costal, Radial and First Cubital); pterostigma about 0.4 × as wide as long, anterior board outcurved; 2r-rs&Rs sector vein long; Rs&M reaching Sc+R far from pterostigma. Hind wing with one straight hamulus, and four distal hamuli equally distant, and strongly curved. Legs. Profemur swollen, 2.7 × as long as wide, apical half of ventral margin serrulate. Metatrochanter (Fig. 3G View Figure 3 ) without spine. Metafemur (Fig. 3G View Figure 3 ) with one acute spine in ventral midline, 0.26 × as long as metafemoral width, touching apical margin of metatrochanter, and with one small, broad and dentate protuberance ventrally, 0.04 × metafemoral width, located on second quarter of metafemur.
Metasoma. Weakly longer than mesosoma. Seventh sternite (Fig. 3F View Figure 3 ) with posterior margin incurved at about middle third. Hypopygium (Fig. 3E View Figure 3 ) with spiculum longer than median length of hypopygium, and 1.3 × longer than anteromedial apodeme, latter strongly curved mesad apically; posterior margin strongly incurved, lateral lobe obtuse rounded. Genitalia (Fig. 3C, D View Figure 3 ). Harpe shorter than gonostipe; aedeagus slightly wide, 2.32 × as long as wide, apex aedeagus posterior to posterior margin of gonostipe, 0.6 × as long as gonostipe; basivolsella large, 0.6 × as long as gonostipe, basal half about as wide as apical half, basal margin incurved.
Variation.
Mesosoma more polished, expecially pronotum and propodeum.
Etymology.
The specific epithet derived from the Latin word for robust, and refers to the robust body of this species.
Material examined.
Holotype, male, China: Yunnan, Dali , Yunlong County, 2608 m, 25°50'57.94"N, 99°14'30.58"E, 27.xiii- 12.ix.2020, MT, SCAU 3042645 (SCBG) GoogleMaps . Paratypes: 2 males. 1 male, same collecting data as holotype, SCAU 3042641 (SCBG) GoogleMaps ; 1 male, China: Yunnan, Dali , Yunlong County, 2537 m, 25°50'49.91"N, 99°14'22.95"E, 28.v-14.vi.2020, MT, SCAU 3042657 (SCBG) GoogleMaps .
Distribution.
Oriental region, China, Yunnan Province.
Remarks.
This new species is very similar to F. syndesis Chen & Azevedo [Yunnan and Hainan, China], but can be separated from the latter by the following characters: median carina of clypeus incomplete (complete in F. syndesis ); notaulus complete and deep (incomplete and shallow in F. syndesis ); declivity of propodeum without median carina (with median carina in F. syndesis ); metafemur with only one acute spine in ventral midline (with two acute spines in F. syndesis ); lateral lobe of hypopygium without conical protuberance (with conical protuberance in F. syndesis ).
