MATERIAL. Holotype – ♂, Vietnam: Quang Binh Prov., “Dong Chan – Khe Minh”,

~ 1000 m, forest station, N. Orlov, L. Iogansen ( ZIN).

DESCRIPTION. Male (holotype). Coloration and structure of body very similar to those of nominotypical subspecies but with a few small differences in some details of abdominal apex: last tergite with posteromedian process having more parallel lateral edges in proximal two thirds and less developed lateral lobe-like folds in more distal portion (proximal parts of these folds distinctly separated from median part of this process, but their distal parts not separated from it; vs. all parts of these folds clearly separated from median part of this process;

compare Figs 46 and 50 ); both cerci with less strongly curved lateral branch and distinct lobe-like lateral projection near base of this branch (see Figs 47 and 51 ), but left cercus with thinner upper distal lobule and S-shaped posterior (apical) edge of lower distal lobule ( Figs 48

and 52), and right cercus without distinct dorsal denticle in subapical part of upper distal lobule and with lower lobule almost as in left cercus (but in nominotypical subspecies, latter lobule distally wider than in left cercus and different in shape) ( Figs 49 and 53 ).

Female unknown.

MEASUREMENTS. Length (in mm). Body 11; body with wings 22.5; pronotum 3.9;

tegmina 18.5; hind femora 10.5.

COMPARISON. The new subspecies was collected in a more northern province of Vietnam than X. (X.) b. beybienkoi Gorochov, 1993 ; it differs from the latter subspecies in the characters listed above. Differences of X. (X.) b. adjacens subsp. n. from X. (X.) b. thaica

Gorochov, 2016, described from only female, are unclear, but X. b. thaica is distributed farther south than the new subspecies and much farther west than the latter subspecies and X.

subsp. n.; 50–53 – X. (X.) b. beybienkoi Gor. ; 54 – X.? laosi sp. n.; 55 – X.? lampungi sp. n.;

56–58 – Rhinoteratura uniformis (Gor.) ; 59 – Rh. ketambe sp. n.; 60, 61 – Rh. raoani

(Gor.); 62–64 – Rh. pseudocapreola sp. n.; 65 – Rh.? capreola (Redt.) , lectotype; 66, 67 –

Borneratura atromacula sp. n.; 68 – Odonturisca dentata sp. n. Posteromedian process of male last tergite from above/behind (46, 50); male left cercus from above (47, 51); two distal lobules of left (48, 52) and right (49, 53) cerci in male from side/behind. Female genital plate from below (54–56, 59, 60, 62, 66, 68) and from side (64 – with other parts of abdominal apex including ovipositor base, 65 – with only ovipositor base). Distal half of male left cercus,

medial view (57); male genital plate from below (58). Ovipositor apex from side (61, 63, 67).

[61–64, after Gorochov (2008); 65, after photograph in OSF.]

ETYMOLOGY. This subspecies name is the Latin word “adjacens” (adjacent, neigh-

boring) due to the type locality of the new subspecies situated not far from the area of the nominotypical one.
