25) Xiphidiopsis (Xiphidiopsis) gressitti Jin sp. n.

Holotype ♂ (left front leg, right hind leg, both antennae lost): VIETNAM 15–35km / NW of Phan Rang / 8–16.IX.1960; C.N. Yoshimoto / Collector

Paratype ♀ (both front legs and right middle leg, antenna lost): VIETNAM 22 km / S. of Nha Trang / 20– 26.XI.1960; C.N. Yoshimoto / Collector

Diagnosis. General morphology typical of the genus. Male last tergite forming a single (unpaired) middle process, rather thick, asymmetry, apical enlarged into a big irregular lobe; cerci complicated, asymmetry, with broad branch lobes (Fig. 11 a–c), subgenital plate with nearly truncated posterior margin, with long styli (Fig. 11d, only tiny basal part exists now), genitalia not dissected.

Female 9 th tergite with enlarged lateral postal margin; postal margin of subgenital plate elongated with narrowly round margin (Fig. 11e, f), ovipositor sword shape, long and nearly straight, ventral valve smooth, without apical hook.

Measurements (mm). Body: ♂ 10.2, ♀ 10.7; Pronotum: ♂ 3.6, ♀ 3.6; Tegmina: ♂ 16.9, ♀ 19.1; Hind femora: ♂ 10.2, ♀ 10.3; Ovipositor: 8.1–8.3.

Comparison. Very similar to X. (X.) beybienkoi (Gorochov, 1993: Figs. 9–11; Gorochov, 1998: Figs. 5, 6) from Buon Luoi of Vietnam, but the unpaired middle process of male last tergite larger with lateral upper cornicult, female subgenital plate projected in middle into an ellipse lobe with smooth margin instead of shorter plate (Gorochov, 1998: Fig. 5).

Etymology. Species named is in memory of the American Entomologist and Coleopterist, J.L. Gressitt.
