A brief description of eggs, imago and five nymph instars of Conquistator mucronatus with figures are given by Costello et al. (2002). More complete description of the species with paying of special attention to a structure of male and female terminalia which was not described earlier is given below.

Re-description. Body oval, dorsally flattened, ventrally slightly convex. Coloration yellowish with brown maculae on dorsal surface.

Head. Preocular part of head slightly narrowing anteriad. Juga as long as clypeus, with rectangularly rounded outer angles and shallow lateral notches. Rostrum reaches posterior margins of hind coxae, its segment II longest, but shorter than segments II and III united; segment IV brownish. Dorsal surface of head densely covered with small dark points. The middle of vertex, frons and clypeus, narrow stripes on each side of vertex and frons, rather large patches near inner margin of each eye without punctuation. Margins of juga and spots before eyes blackish.

Prothorax. Anterior margin of pronotum slightly incurved, without edge. Lateral margins of pronotum straight, with wide calloused yellow rims, bearing five or six small pointed denticles directed laterad. Anterior angles of pronotum with same denticles as those on lateral margins. Lateral angles of pronotum long, narrowly triangular and strongly bent anteriad, unimucronate, dark brown. Posterior angles of pronotum triangularly rounded, without hamuli. Anterior portion of pronotal disc with distinctly smoothed tubercles on each side covered with points. Cicatrices relatively wide, brown. Pair of large, pale, roundish, calloused patches located behind cicatrices. Entire pronotal disk densely covered with rather large brown points; patches of cuticle between them slightly convex, yellow.

Mesothorax. Scutellum with small calloused patches on basal corners, in middle of basal margin and on apex. Apical part of scutellum narrower than corium at same level. Points of punctuation on scutellum similar to those on pronotum. Carina on mesosternum narrow, extended in anterior part, flattened in posterior part. Posterior margin of each mesopleurite with small patch of porous cuticle in proximal part.

Metathorax. Smooth part (ruga) of evaporatorium expanded distad, without dark spot on rounded distal end, not reaching middle of metapleurite, and completely surrounded by patch of porous cuticle. Metasternum flat, narrowed anteriad and posteriad, with very narrow ribs on lateral margins. Metapleurites without black spots.

Legs pale, tarsi brownish. Profemora without spine, protibiae without carina.

Abdomen. Laterotergites of connexivum pale, with dark spots in anterior inner corners; laterotergite VII with dark inner margin. Each posterior angle of abdominal segments short and obtuse; posterior angles of segment VII widely triangular, rounded apically. Ventral surface of abdomen pale, covered with colorless points, without black spots. Spine on base of abdomen round in transversal section, reaches middle of hind coxae.

P ygophore ( Fig. 2 ) as wide as long, its lateral walls in parallel planes. Lateroapical angles of pygophore short, rounded, located at level of ventroapical margin of pygophore, with short thickened setae on their apices. Dorsoapical margin of pygophore ( Fig. 2 , da. m) located below its ventroapical margin, with shallow notch along its whole width and several setae on each side. Dorsal infolding short. Ventroapical margin of pygophore ( Fig. 2 , va. m) strongly bent dorsad, with uniform small medial and lateral notches. Impression of ventral surface of pygophore deep, with distinct, weakly concave basal margin located on level of pygophoral ventroapical margin and covered like it with dense long setae. Dorsal parandria ( Fig. 2 , d. prd) approximately as wide as long, narrowed on ventral end and widely rounded on dorsal end. Outer margins of parandria with deep notches, inner margins strongly convex, bearing as well as upper parandrial surfaces small rounded tubercles. Ventral parandria (presented in some other taxa of Asopinae ) absent.

Paramere ( Fig. 1 ). Basal plate rounded. Inner angle of sensory process ( Fig. 1 , s. pr) acute and slightly extended. Corpus of paramere wide in basal part, with long narrow digitiform process ( Fig. 1 , l. pr) on apical part of inner surface basally of hypophysis. Digitiform process directed anteriad and to medial line of pygophore. Hypophysis long and rather narrow, directed anteriad and slightly outside. Inner branch of hypophysis ( Fig. 1 , inn. br) short, acute-angled, directed anteriad. Apex of hypophysis ( Fig. 1 , apx) shorter and wider than its inner branch, directed outside. Inner and outer margins of hypophysis concave.

Aedeagus ( Fig. 13 ). Phallobase as long as wide, widening caudad, with rather narrow ventral processes. Basal and apical parts of theca ( Fig. 13 , a. th, b. th) subequal in length. Ventroapical notch of apical part of theca shallow, widely rounded. Base of conjunctiva with weakly sclerotised patch on each side. Ventrolateral lobes of conjunctiva ( Fig. 13 , vl. l) long, moderately wide basally, narrowing apicad, without sclerites on their apices. Ventrolateral lobes directed ventrolaterad and arcuately bent towards base of aedeagus. Apex of conjunctiva ( Fig. 13 , a. con) roundish, its length slightely more than its width. Ventral lobe of conjunctiva rather short. Longitudinal bands of medial penal plates ( Fig. 13 , l. b) parallel, narrow, weakly extending distad. Membranous surface between them convex on total length. Apical processes of medial penal plates ( Fig. 13 , a. pr) short, converge, but not contiguous. Vesica ( Fig. 13 , ves) appearing as short tube.

Female genitalia ( Figs 16, 17 ). Posterior margins of gonocoxites 1 strongly convex in outer part. Each gonocoxite 1 with deep impression on internal surface in its inner part near posterior margin. Medial genital plate rectangular, with straight posterior margin. Paratergites IX wide, with rather strong convex inner and straight outer margins. Paratergites VIII wider than long, with widely rounded outer angles, straight posterior margins and very small spiracles in anterior corners. G ynatrial sclerites. Basal sclerites ( Fig. 16 , b. s) moderately wide, in form of crescent, strongly narrowed on anterior and posterior ends. Round sclerites ( Fig. 16 , r. s) small. Annular clerite ( Fig. 16 , ann. s) rather short, roundish. Conoid sclerite ( Fig. 16 , con. s) longer than its width and slightly expanded in its anterior part. Spermatheca. Proximal part of spermathecal duct ( Fig. 17 , pr. d) nearly reaching middle of abdominal sternum VII. Medial part of duct not reach anterior margin of sternum VI. Proximomedial part (membranous dilation) of duct ( Fig. 17 , prm. d) narrowed in its base; distomedial part (sclerotized rod) of duct ( Fig. 17 , dm. d) without dilation before its posterior (morphologically anterior) end. Proximal collar of spermathecal pump reduced. Capsule ( Fig. 17 , cap) roundish, slightly shorter than pump.
