Hedycryptus ohshimensis (Uchida, 1930) comb. nov.
( Figs. 1C, J View Fig , 2E, L, M View Fig , 3F View Fig , 8A–H View Fig ) Cryptus ohshimensis Uchida, 1930b: 81 .
Description. The original description of this species ( Uchida, 1930b) lacks some important character states. In addition, the male of this species undescribed. Thus, I redescribe this species with the data of males below.
Female (n=7). Body length 14.5–16.0 mm, mat, covered with silver setae.
Head 0.6 times as long as wide. Clypeus 0.5 times as long as wide, convex ( Fig. 1C View Fig ), punctate except for anterior 0.3. Face 0.5 times as long as wide, convex medially ( Fig. 1C View Fig ). Frons concave, covered with rugae dorsally ( Fig. 8C View Fig ), smooth ventrally. Occipital carina complete, its lower end joined with hypostomal carina. MSL 0.8–0.9 times as long as BWM. OOL 1.0–1.1 times as long as OD. POL 0.9–1.1 times as long as OD. Antenna with 39–40 flagellomeres. F1 1.5 times as long as F2.
Mesosoma. Epomia present. Lateral area of pronotum covered with minute rugae, with striation posteriorly ( Fig. 8D View Fig ). Notauli shallow but distinct on anterior half of mesoscutum. Scutellum weakly convex ( Fig. 8A View Fig ), densely punctate. Epicnemial carina distinct, its dorsal end not joined with anterior margin of mesopleuron and subalar prominence. Mesopleuron and metapleuron covered with minute rugae ( Fig. 8D View Fig ). Propodeum with anterior transverse carina, posterior transverse carina and basal section of lateromedian longitudinal carina ( Fig. 8E View Fig ). Pleural carina of propodeum absent except for anterior part. Propodeal apophysis well-developed ( Fig. 8E View Fig ). Propodeal spiracle elongate. Fore wing length 11.5–12.5 mm. Areolet present, hexagonal, with sides convergent anteriorly ( Figs. 1J View Fig , 8A View Fig ). Second recurrent vein simply arched ( Figs. 1J View Fig , 8A View Fig ). Nervulus opposite to basal vein ( Fig. 8A View Fig ). Nervellus intercepted posterior to midpoint ( Fig. 8A View Fig ). Hind femur 6.3–6.4 times as long as maximum depth in lateral view. Hind TS2: TS1, TS3, TS4 and TS5 = 2.0: 4.0–4.2, 1.1–1.2, 0.5–0.6 and 0.9–1.1.
Metasoma. T1 2.3–2.6 times as long as maximum width, without a pair of small triangular teeth at base, terete anteriorly ( Figs. 2E, L, M View Fig ). Median dorsal carina of T1 absent except for longitudinal keel of postpetiole ( Figs. 2E, L View Fig ). Dorsolateral carina of T1 absent anteriorly, present posteriorly. T2 1.0–1.1 times as long as maximum width, covered with fine and dense setae ( Fig. 8F View Fig ). Ovipositor sheath 1.05–1.1 times as long as hind tibia. Apex of ovipositor as Fig. 3F View Fig .
Coloration ( Figs. 8 View Fig A-F). Body (excluding wings and legs) black, except for: mandible, clypeus, median part of face, scape and pedicel partly tinged with reddish brown to yellow; dorsal part of F4–F8 (sometimes also F3 and F9) white; dorsal part of facial orbit, frontal orbit and vertical orbit yellow; temporal orbit narrowly yellow; median part of anterior margin of collar tinged with yellow; tegula brown; base of T1 and S1 yellowish brown; posterior margin of T2–T7 narrowly tinged with reddish brown; thyridium and ovipositor reddish brown. Wings hyaline; veins and pterostigma blackish brown to brown except for yellow wing base. Legs black to blackish brown, except for: fore and mid legs except blackish brown area of coxae yellowish brown to brown; fore and mid coxa sometimes tinged with brown; ventral part of hind trochanterllus yellowish brown; hind femur, tibia and tibial spurs brown; apical part of hind TS1, TS2–TS4 and base of TS5 white to whitish yellow.
Male (n=2). Similar to female ( Fig. 8G View Fig ). MSL 0.6 times as long as BWM. F1 1.3–1.35 times as long as F2. F19–F23 (sometimes also F24) with a tyloid ( Fig. 8H View Fig ). Hind femur 6.7–7.0 times as long as maximum depth in lateral view. Hind TS2: TS1, TS3, TS4 and TS5 = 2.0: 3.6–3.7, 1.3–1.4, 0.6 and 0.9. T1 3.95 times as long as maximum width. T2 2.25–2.4 times as long as maximum width. Body (excluding wings and legs) black, except for: face, clypeus, all orbits except for dorsal end of temporal orbit, malar space, ventral part of scape and pedicel, collar, posterodorsal corner of pronotum, posterior area of propleuron, scutellum, tegula and subalar prominence yellow; mesopleuron and mesosternum sometimes with yellow spot(s); coloration of metasoma similar to female but T4–T7 sometimes largely tinged with reddish brown. Legs paler than female. Hind coxa with yellow area ventrally and sometimes also basodorsally. Hind TS1 white to whitish yellow except for narrow brown area at base.
Specimens examined. JAPAN: SEHU, F (holotype), Tokyo, Izu-Oshima Is., 25. V. 1924, M. Yamanaka leg. ; NIAES, 6 F & 2 M, Tokyo, Izu Islands , Toshima Is., 23. X. 1975 (host collect), II. 1976 (emerged), Y. Umeda leg.
Distribution. Japan (Izu-Oshima Is. and Toshima Is.*).
Bionomics. In NIAES, a label with “ Trachysphyrus sp. ex. Descoreba simplex BUTL. pupa” put on along the above specimens from Toshima Island. If the combination between specimens and this label is true, Descoreba simplex Butler, 1878 ( Geometridae ) is the host of this species.
Remarks. This is the first record of the male of this species. This species resembles H. tenuiabdominalis but can be distinguished by the following combination of character states: body large, more than 14.5 mm (usually less than 14.0 mm in H. tenuiabdominalis ); base of T1 with a conspicuous yellow area ( Figs. 8A, G View Fig ) (completely black in H. tenuiabdominalis ); F19–F24 with a tyloid in male ( Fig. 8H View Fig ) (from F15 or F16 to F22 or F 23 in male of H. tenuiabdominalis ).
