( Figs 258–263 View FIGURES 258 – 261 View FIGURES 262, 263 , 285, 287, 288 View FIGURES 283 – 288 )

Type material. Holotype ♀ ( QSBG), on slide ( Fig. 259 View FIGURES 258 – 261 ) labelled: 1. “ Thailand: Petchabun Khao Kho Nat. Park, office 16°39.479'N 101°08.105'E 12–19.vii.2006, MT, S. Chatchumnan & S. Singtong”. 2. “ Holotype Tanyxiphium longissimum Huber Holotype ♀ dorsal”.

Paratypes. 8 ♀. THAILAND. Chiang Mai. Doi Inthanon Nat. Park, 18°31.559'N 98°29.941'E, 1700m, 9– 16.viii.2006, MT, checkpoint 2, Y. Areeluck (1 ♀, CNC). Petchabun. Same data as holotype (3 ♀, QSBG, CNC); same data as holotype but 19–26.vii [16°39.550'N] and 26.vii-2.viii (3 ♀, QSBG, CNC); Khao Kho Nat. Park, 16°39.257'N 101°07.945'E, 186m, 5–12.ix.2006, MT, S. Chatchumnan & S. Singtong, mixed deciduous forest (1 ♀, QSBG).

Diagnosis. Tanyxiphium longissimum differs from T. seychellense by the uniform colour of the mesosoma, fl5 with 2 mps and fl6 usually with 1 mps, the narrower wings, the relatively longer and narrower gaster, and the longer ovipositor sheaths. It differs from T. breviovipositor and T. perforator (Ogloblin) by the much longer ovipositor sheaths.

Description. FEMALE. Body length 970–1050 (n=6). Colour. Body yellow, with vertex posteriorly and upper half of occiput brown, scape except radicle and pedicel light brown, flagellum and ovipositor sheaths dark brown, apical half of metatibia and all tarsi brown.

Head. Head width 311–327 (n=3). Antenna. Funicle segments fl5, fl7 and fl8 each with 2 mps, fl6 usually with 1 mps, occasionally 0 or 2 mps on one or both antenna. Length/width measurements (n=3): scape 237–253/39–43, pedicel 72–78/36–38, fl1 56–62/22–23, fl2 41–56/21, fl3 53–62/21–22, fl4 50–61/21–23, fl5 73–82/24–29, fl6 68–72/ 24–26, fl7 74–82/28–32, fl8 70–77/35–70, clava 203–217/56–65. Mesosoma. As in generic description ( Fig. 262 View FIGURES 262, 263 ). Wings. Fore wing length (n=3) 1083–1169, width 266–288, length/width 4.06–4.13, longest marginal setae 85–94. Hind wing length (n=3) 866–941, width, 26–27, longest marginal setae 103–112. Metasoma. Gaster about 2.5× as long as wide. Ovipositor sheath length 2126–2414, 4.66–4.80× metatibia length (452–518), with exserted part at least 1.5× as long as entire body length.

MALE. Unknown.

Etymology. From longus, Latin for long, and - issimus, adjectival superlative, referring to the very long ovipositor sheaths.
