Genus Pseudalomya TELENGA occupies an intermediate position between tribes Alomyini and Phaeogenini , but more close to the representatives of the last. As of Phaeogenini pronotum is without distinct hollow at border with mesonotum, only with slight impression, postscutellum with distinct lateral foveae, front legs with two trochanters. As of Alomyini occipital carina of females closes above mouthparts at the bottom, frons above antennal cavities of males and of females with high horn compressed from sides, spiracles oval, not a circular.

F e m a l e

F l a g e l l u m: Filiform, 30-segments, thick, first segment short, almost square, only 1,1 times longer than the width at the top, with white annulus on segments 8-15, beyond white annulus not widened and not flattened ventrally. Scape cylindrical, practically without dorsal cavity. Flagellum of female 1,8 times shorter than the front wing and 2,5 times shorter than body length.

H e a d: Head contour from the front only just narrowed downwards to mandibles, slightly transversal, 1,1 times wider than height; genae from front 3,1 times shorter than height of eye; eyes not great, temples from the front visible almost to middle of eye; head contour from above strongly stout, transversal, 1,4 times wider than length, weakly roundly narrowed behind eyes. Vertex from lateral practically not slanting down, on the contrary rather climbing from hind margin of lateral ocelli; temples long 1,6 times longer longitudinal diameter of an eye at the middle, from above slightly roundly narrowed behind eyes; occipital carina sharp all round, from above strongly roundly impressed, not reach level of eyes and hind ocelli, at the bottom connected above mouthparts; hyposto- mal carina visible from lateral also connected above mouthparts (as at Alomya); malar space 1,5 times longer than the mandible base; mandibles broad, flat, curved with rounded apex, at bottom margin with only just expressed notch, marking apex of reduced lower tooth; clypeus transverse, slightly convex, 2,3 times wider than height, with rounded front margin, separated from face by suture, medially subapically with tooth, front margin thick, slightly elevated medially; clypeal foveae narrow, deep; labrum not protrude from under clypeus; middle field of face slightly elevated above lateral fields, in middle narrower than lateral fields; antennal cavities deeply impressed reach ocelli and not reach borders of eyes, with sharp teeth between antennal fossae and strong transversal wrinkles; margins of antennal fossae slightly elevated above face surface; frons above antennal fossae with high horn compressed from lateral, with transversal wrinkles converging to its base; ocelli small, flat, diameter of lateral ocellus 2,1 times less than distance from ocellus to eye; ocellar triangle not expressed; surface of clypeus and face slightly superficially wrinkled, middle field with big, sparse, smoothed punctures without microsculpture, other part of head smoothly-wrinkled without microsculpture.

T h o r a x: Collar of pronotum very long, flat, with straight front margin (from above); transverse furrow of pronotum shallow, medially interrupted by fan-shaped disperse ribs; epomiae sharp; pronotal base gradually curved; pronotum without fovea at border with mesonotum. Mesonotum only just convex, 1,2 times longer than width; notauli long, reach middle of mesonotum; surface of mesonotum wrinkled, without microsculpture; mesonotum laterally bordered by strong impression; axillary tongue slightly expressed; subalarum high, thick; speculum slightly wrinkled, shining; area of mesopleural fovea in form of narrow longitudinal impression; mesopleural suture straight, deep, interrupted by very delicate short ribs; mesopleurae at bottom without sharp bend; sternauli distinct to middle of mesopleurae; lower part of mesopleurae longitudinally wrinkly-punctured, shining, without microsculpture, upper third slightly wrinkly-punctured; scutellum flat, laterally not carinated, smoothly punctured by big punctures; postscutellum with longitudinal ribs and distinct lateral foveae. Hind margin of metanotum with blunt triangular projections opposite base of lateral longitudinal carinae. Propodeum long, broken from lateral, length of horizontal part 1,5 times longer area posteromedia in middle; most carinae of propodeum reduced, with exception of metapleural carina and apical transverse carina, lamellate widened at place of apophysises; lateral longitudinal carinae marked only at base; spiracles small, oval, by external contour 1,5 times longer than width. Surface of propodeum irregularly-wrinkled, without microsculpture.

L e g s: Strong, short. Hind coxae without scopa. Claws thin, long, uniformly gradually curved. All legs with two trochanters.

W i n g s: Narrow and long; areolet pentagonal, symmetrical with wide base; stigma normal, light, radial cell narrow, blunted at apex, radius straight, bent at apex; nervulus interstitial; ramulus absent; all veins of front wing dark, except slightly developed apical branch of median vein; membrane of wing hyaline; external branch of radial vein of hind wing slightly expressed. Length of front wing almost two times more than length of flagellum and 1,4 times of body length.

A b d o m e n:Amblypygous, from above fusiform, apical tergites not hidden; length of second tergite approximately equal to width at apex; sheath of ovipositor only just visible protrude. First tergite from lateral with gradual bend between petiolus and postpetiolus; petiolus not flattened at base, from lateral carinated only by ventrolateral carina and sculpturated by smoothed ribs; from above petiolus gradually broadened to triangle postpetiolus; distance between spiracles equal to distance from spiracles to hind margin of tergite; middle field of postpetiolus not expressed, its surface irregularly-wrinkled, without microsculpture. Gastrocoeli and thyridia not developed, on theirs place short carina between lateral and dorsal surfaces of tergite; lunulae absent, spiracles situated in middle of lateral surface of tergite; surface of second tergite to apex slightly superficially-wrinkled, without microsculpture, shining; other tergites smooth. Hypopygium, without longitudinal fold, but not flattened, reach apex of abdomen; sternites 4-5 with fold.

C o l o r a t i o n: Body black; head, legs, except hind coxae, partially pronotum, mesonotum and scutellum brown-red.

Body of female with moderately dense long white pubescence.

S i z e: Body length: 12,5; front wing: 9,0; flagellum: 5,0 mm.

The species is characterized by sharply expressed sexual dimorphism.

M a l e

Body more thin and slender. Flagellum of male slender, bristle-shaped, 39-segments and with slightly differentiated elongated segments, uniformly light colored without white annulus and tyloides; hypostomal and occipital carinae not closed above mouthparts; vertex from lateral slanted from middle to occipital carina; mandibles with two distinct teeth; notauli very sharp; mesopleurae polished with large smoothed punctures without rugosity; legs slender and long; all tergites of abdomen smooth, polished; in coloration light-red and yellow color dominate.
