( Figs 1–13 View FIGURES 1 – 7 View FIGURES 8 – 13 , 31, 33 View FIGURES 31 – 34. 31 and 33 , 35 View FIGURES 35 – 37 , 38, 39 View FIGURES 38 – 39 )

Holotype. female, China, Hunan, Sangzhi, VII.1981, Ex. Protohermes sp., Coll. DX Liao ( IZCAS). Paratypes: 4 females, 4 males, data the same as holotype.

Description. Female (Holotype): length excluding ovipositor 1.25 mm ( Fig. 35 View FIGURES 35 – 37 ). Head dark brown with green sheen; malar space area with coppery sheen; antenna with scape yellow; pedicel and flagellum dark brown; maxillary and labial palpi yellow; pronotum, mesoscutum, axilla, and anterior half of scutellum dark brown with slight green sheen; apical half of scutellum with metallic green sheen; tegula and mesopleuron yellow; legs yellow except hind femur pale brown dorsally ( Fig. 6 View FIGURES 1 – 7 ); propodeum pale brown; wings hyaline; ovipositor sheath dark brown.

Head. Frontovertex with polygonal reticulate sculpture, clothed with sparse black setae, about one-third head width; ocelli forming an acute angle; eyes clothed in very fine, inconspicuous setae and slightly overreaching sharp occipital margin; torulus midway between lowest eye margin and clypeus, separated from each other by about 1.5× own diameter; antenna with scape subcylindrical, 5× as long as broad; pedicel subtriangular, as broad as scape, 1.8× as long as broad; funicle with F1–F3 subequal in length, moniliform, F4 and F5 equal in length and width, F6 widest, ratio of width and length for each segment: 1.3, 1.7, 1.3, 1.25, 1.25, 1.5; clava 3-segmented, its apex with a distinctly oblique truncation ( Fig. 1 View FIGURES 1 – 7 ); mandible with three acute teeth ( Fig. 9 View FIGURES 8 – 13 ); maxillary and labial palpi 4- and 3- segmented respectively.

Mesosoma. Dorsum clothed with fine setae except apical half of scutellum smooth; pronotum very short, about one sixth as long as mesoscutum, with polygonal reticulate sculpture; mesoscutum subquadrate, about 1.4× as broad as long, sculpture as pronotum; scutellum about 1.3× as long as broad, sculpture anteriorly similar to that of mesoscutum, posteriorly shallower and smooth; fore wing ( Fig. 2 View FIGURES 1 – 7 ) about 2.5× as long as broad; costal cell with more than one line of setae dorsally; linea calva more or less closed by a single line of setae dorsally; marginal vein about as long as postmarginal vein but more or less shorter than stigmal vein, which is more or less scimitar shaped.

Metasoma. Shorter than mesosoma; hypopygium reaching slightly more than two-thirds length of metasoma; ovipositor clearly exserted ( Fig. 7 View FIGURES 1 – 7 ), relative proportion of OL and MT: 134:54.

Relative measurements. HW 57, HL 48, FV 18, FVL 21, POL 8, AOL 4, OOL 1, OCL 2, POD 5, AOD 3, EL 34, EW 17, MS 18, SL 25, SW 5, PL 9, PW 5, CL 19, CW 9, FWL 176, FWW 71, HWL 117, HWW 27, MT 54, MTS 14, OL 134, GL 47.

Male. Head mostly orange yellow except ocellar area dark brown and gena marked with brown spot; dorsum of mesosoma and metasoma dark brown; mesopleuron and legs yellow; wings hyaline.

Head. Frontovertex with regular polygonal reticulate sculpture and clothed in relatively long setae; eyes clothed in very fine, inconspicuous setae; antenna ( Fig. 31 View FIGURES 31 – 34. 31 and 33 ) with scape about 4.3× as long as broad; pedicel 2× as long as broad; all funicle segments moniliform, and more or less gradually larger toward apex; clava entire.

Mesosoma. Dorsum clothed in dense setae; mesopleuron slightly reduced in size relative to female, posteriorly slightly separated from propodeum ( Fig. 38 View FIGURES 38 – 39 ); fore wing 2.3× as long as broad.

Metasoma. About as long as mesosoma; genitalia ( Fig. 33 View FIGURES 31 – 34. 31 and 33 ) with distinctly long and slender aedeagus, about 1.4× as long as mid tibia; phallobase with elongate parameres and digiti, each of which with one apical hook.

Relative measurements. SL 26, SW, 6, PL 10, PW 5, FWL 149, FWW 66, MT 49, AL 71.

Host. Protohermes sp. ( Megaloptera : Corydalidae ).

Distribution. China (Hunan).

Etymology. The specific epithet is derived from the latin words “long” and “caud” referring to the long ovipositor sheath for the new species.
