spite the great number of species described, it is only in very few species in which more than one morph appear is known. Among the Palaearctic fauna, only in P. putoni (NOUALHIER, 1895) and P. mosconai WYGODZINSKY, 1952 were macropterous and apterous specimens reported (RlBES et al. 1997, LINNAVUORI 1974). Ploiaria turkestanica P. V. PUTSHKOV, 1984 was described based on a single macropterous male from the Asian part of Kazakhstan. Only the macropterous male holotype of this species has hitherto been known. In the course of my work on the reduviid material of the HNHM and NHMW, I have found some old specimens from Armenia and Azerbaijan, which represent the apterous form of this species. No further material could be found either in the ZMYA (M. MARJANYAN, pers. comm.) or in the ZMAS (I. M. KERZHNER, pers. comm.). To help recognize the species, the apterous specimens are briefly described below. Ploiaria turkestanica P. V. PUTSHKOV, 1984 Ploiaria turkestanica P. V. PUTSHKOV, 1984: 17. HT: o

, Kazakhstan; ZMAS. Material examined - 1 "Armenia, Ordubat" (= Ordubad, Azerbaijan), "Coll. Horváth", in the HNHM; 1 $, "Caucasus. Armen. Geb. Leder. Reitter", "Ploiaria n. sp.", "Coll. Horváth", in the HNHM; 2 ÇÇ, "Caucasus. Araxesthal. Leder. Reitter.", in the NHMW. Description of apterous morph - Male and female. General aspect of male as shown in Fig. 12. General colour light ochraceous; each side of head before eye with pale brown spot, outer surface of fore femora apically very pale brown. Mid and hind femora with light apical annulus. Abdominal tergites III—VII with characteristic brown pattern submedially (Figs 16,17), posterior half of connexival segments brown. Ventral and posterior parts of pygophore as well as its posterior prolongation dark brown (Figs 18-20). Dorsal surface of head and pronotum slightly granulated. - Head as shown in Figs 14-15, about 1.6 times as long as wide across eyes. Anteocular part elongate, produced forward between bases of antennae; tylus extending beyond jugae. Postocular part short, broadly rounded, basally gradually converging to form a short neck in lateral view. Vertex with transverse furrow between eyes. Eyes relatively small, prominent, globose, remote from level of dorsal and ventral surface of head in lateral aspect. Diatone 1.9 times as wide as interocular distance. - Pronotum as shown in Figs 14 and 15, 1.6 times as long as its greatest width, swollen anteriorly, conspicuously narrowing posteriorly. Fore lobe subglobular, sharply separated from hind lobe, latter very short, leaving mesonotum entirely exposed. Mesonotum considerably broadened, metanotum about half as long as mesonotum, meso- and metanota combined almost as long as pronotum. - Fore leg as in Fig. 13. Coxa elongated, 6.4 times as long as its greatest width, slightly shorter than tibia. Trochanter with a conspicuous ventral projection bearing a strong, spine-like seta and with another spine-like seta on its medial surface. Femur moderately incrassate, 6.3 times as long as its greatest width, with 2 rows of spiniferous tubercles. Tibia about 0.6 times as long as femur, its ventral surface with a row of inclined short spines. Tarsus about half as long as tibia, segment I 1.2 times longer than segments II and III together. - Abdomen constricted basally, compressed dorsoventrally. Male: as shown in Fig. 17, oblong elliptical, 2.2 times wider than greatest width of pronotum. Posterior border of pygophore with a long, curved prolongation directed upward, narrowing evenly to its end, bearing a basal widening;
