Diagnosis. Tanyxiphium breviovipositor differs from the three other described Tanyxiphium species by the short ovipositor sheaths that are only slightly exserted beyond the gaster apex. The other described species have much longer, distinctly exserted ovipositor sheaths.
Description. FEMALE. Body length 691–819 (n=10). Colour. Antenna except scape and pedicel laterally and ventrally, head and mesosoma except (usually) a streak along outside of notauli and inside of axilla and axillula, and ovipositor plates brown. Metasoma lighter, mottled with brown dorsally as follows: gt2–gt6 laterally and medially (lighter brown), these areas usually (not on gt5 and gt6) separated by lighter (white) areas sublaterally along anterior margin. Scape and pedicel except dorsally, legs except femora, and sublateral streak on mesosoma yellowish or at least lighter in colour. Head. Head width 282–305 (n=2). Antenna. Funicle segments fl7 and fl8 each with 2 mps (Fig. 249). Length/width measurements (n=3, but 2 for scape and pedicel): scape 197–216/31–34, pedicel 60–63/32–33, fl 1 30–35 /17–18, fl2 32–33/13–19, fl3 36–38/15–18, fl4 34–36/15–18, fl5 38–44/16–18, fl6 38– 41/18–20, fl7 48–55/22–23, fl8 51–56/28–30, clava 168–194–42–47. Mesosoma. As in generic description (Fig. 252). Wings. Fore wing (Fig. 251) length (n=3) 755–808, width 210–235, length/width 3.44–3.60, longest marginal setae 83–90. Hind wing length (n=3) 614–702, width 19–21, longest marginal setae 88–92. Metasoma. Gaster (Fig. 253) at most 2.5× as long as wide. Ovipositor sheath (Fig. 254) length (n=3) 339–451, 1.21–1.25× metatibia length (279, n=2), not or only slightly exserted beyond apex of gaster.
MALE. Body length ~ 824 (n=1, from slide mount, dissected). Colour. Body except for longitudinal white submedian bands on pronotum more uniformly brown than in female. Antenna. Measurements (n=1) (Fig. 256): scape ~ 135, pedicel 56, fl1 50, fl2 53, fl3 62, fl4 60, fl5 64, fl6 66, fl7 66, fl8 70, fl9 70, fl10 68, fl11 ~ 81; total flagellar length ~ 710; fl6 length/width 3.23, with about 7 mps. Metasoma. Genitalia as in generic description (Fig. 257).
Etymology. From brevis, Latin for short, and ovipositor, referring to the relatively short ovipositor of this species.
