Figs 37–38 Type material. Holotype . ♀ , China , Hainan Prov. , Ledong , 26.VIII.1984 , Chen Zhiqing, No. IOZ(E)1964584 ( IZ- CAS ). Diagnosis. This new species is very similar to S. longicaudata van Achterberg, 1993 , but can be separated from the latter by the following characters: in dorsal view temples gradually narrowed behind eyes (parallel-sided behind eyes in S. longicaudata ); wing membrane dark brown, with a light streak below basal of pterostigma (yellow, smoky brown apically); middle leg largely blackish brown, but coxae yellow, and trochanters infuscate (yellowish brown); medio-basal area of second metasomal tergite rugose (smooth); ovipositor sheath 1.5 × as long as fore wing (4.5 ×); anterior 2/3 of fourth tergite with longitudinal striae (entirely smooth or anterio-lateral areas weakly rugose). Description. Holotype , ♀ , length of body 11.8 mm , of fore wing 10.5 mm , of ovipositor sheath 15.8 mm . FIGURE 36.

FIGURE 37. Shelfordia obscuripennis sp. nov. , ♀, holotype, habitus lateral. Head . Antenna with 48 antennomeres; first flagellomere 1.3 × longer than second flagellomere; first, second and penultimate flagellomeres 2.0, 1.4 and 1.1 × longer than their maximum width, respectively; scapus rather slender, 2.2 × longer than its medial width, long setose ventrally, somewhat compressed, its outer apex more or less truncate, dorsally slightly shorter than ventrally ( Fig. 38k ); maxillary palp incomplete; malar suture developed, with some short setae and sculptured ( Fig. 38g ); labio-maxillary complex moderately protruding, approx. 0.7 height of eye; clypeus flat, not elevated above plane of face, with a few long setae, no dorsal carina and largely coarsely punctate; eye not emarginate ( Fig. 38g ); face flattened, sparsely punctate and short setose, with curved groove to antennal sockets ( Fig. 38g ); frons with shallow median groove, distinctly concave, largely smooth, medially glabrous, and laterally setose ( Fig. 38h ); vertex convex and largely smooth except for a few punctures; shortest distance between posterior ocelli: shortest diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 5: 6: 21; length of malar space equal to basal width of mandible; in dorsal view length of eye 1.6 × temple; temples linearly narrowed behind eyes ( Fig. 38h ). Mesosoma . Length of mesosoma 1.5 × its height ( Fig. 38c ); notauli complete ( Fig. 38d ); mesoscutum smooth and sparsely short setose ( Fig. 38d ); scutellar sulcus deep, moderately narrow, with crenulae ( Fig. 38d ); scutellum smooth, with some short setae posteriorly; metanotum moderately convex medially, without median carina anteriorly ( Fig. 38d ); propodeum largely smooth except for a few crenulae posteriorly, without medio-longitudinal carina, and sparsely setose medially, with dense long setae laterally ( Fig. 38d ). Wings . Fore wing ( Fig. 38a ): SR1: 3-SR: r = 33: 30: 5; angle between 1-SR and C+SC+R about 40°; 1-SR short and linear with 1-M; 1-M straight; 1-SR+M bent basally; cu-a long and straight, weakly postfurcal; 1-CU1: 2-CU1 = 1: 7; 2-SR: 3-SR: r-m = 6: 15: 5; r-m sinuate; 2-SR without widened part; base of 3-SR slightly widened; second submarginal cell hardly widened distally. Hind wing ( Fig. 38b ): 2-SC+R 0.4 × longer than 1r-m; SC+R1: 1r-m = 31: 20; area near cu-a largely glabrous. Legs . Hind coxa weakly punctate; all tarsal claws robust, basally with some long setae; length of fore femur: tibia: tarsus = 29: 31: 44; length of hind femur: tibia: basitarsus = 39: 64: 22; length of femur, tibia and basitarsus of hind leg 4.3, 9.1 and 7.3 × their maximum width, respectively; length of hind tibial spurs 0.27 and 0.32 × hind basitarsus.

Metasoma . Length of first tergite 1.1 × its apical width, its surface largely smooth, slightly concave basally, median area distinctly elevated, weakly rugose posteriorly, dorso-lateral carinae complete and strong, medio-longitudinal carina present but absent posteriorly, lateral grooves relatively wide and sparsely crenulate ( Fig. 38j ); triangular medio-basal area of second tergite smooth, connected to medio-longitudinal carina, carina absent near posterior margin of second tergite, and surrounded by curved and dense striae; oblique anterior grooves of second tergite wide, deep and strongly crenulate, and antero-lateral triangle areas small and smooth ( Fig. 38e ); second suture deep, wide and crenulate medially and narrow laterally ( Fig. 38e ); third tergite largely longitudinally striate, antero-lateral areas distinctly elevated and weakly rugose, antero-lateral grooves deep and complete, with crenulae ( Fig. 38e ); fourth tergite largely smooth but medio-basally longitudinal striate, antero-lateral areas weakly rugose, and antero-lateral grooves crenulate; fifth–seventh tergites smooth, and without antero-lateral areas or depressions ( Fig. 38e ); hypopygium acute apically, reaching beyond level of apex of metasoma; ovipositor sheath 1.5 × as long as fore wing. Colour . Head and mesosoma largely reddish brown ( Fig. 37 ); antenna (but scapus yellowish brown apically), eye, mandible apically and propodeum posteriorly black ( Figs 38d, 38g , 38i ); legs largely black, fore and middle coxa reddish brown, and middle trochanter infuscate ( Fig. 38f ); metasoma and ovipositor sheath black ( Figs 37 , 38e ); wing membrane blackish brown, but fore wing with a pale oblique stripe at vein 2-SR+M, pterostigma and veins dark brown ( Figs 38a, 38b ). Biology. Unknown. Distribution. China ( Hainan ). Etymology. Named after the blackish brown wing membrane: “obscurus” is Latin for “dark” and “pennis” is Latin for “wing”.
