description: Thagria coniunctionis, sp. nov.   
(Plate 1E, Figs. 29–35)  
 Length. Male 7.00–7.50 mm; female unknown.   
 External morphology. Medium size, slender species. General color dark brown with cells of forewings partially translucent, veins black. Crown light brown; eyes black; pronotum dark brown to black with numerous light brown spots; mesonotum light to dark brown with light brown markings; forewings with small, yellow chevron markings in anteapical cells (Plate 1E); face light to dark brown with few suffused brown markings. Head slightly narrower than pronotum, anterior margin obtusely rounded; crown broad, about as wide as eye width, produced distally about ¼ entire length, lateral margins convergent basally, disk depressed; eyes large, semiglobular; pronotum large, about as long medially as crown, surface bullated; mesonotum large, about 1/3 longer medially than pronotum; forewings typical; clypeus long, narrow, lateral margins slightly excised near antennal sockets; clypellus short, base slightly narrower than base of clypeus at juncture of clypeal suture, nearly flat, lateral margins parallel, apex rounded.   
 Male genitalia. Pygofer in lateral view with long, narrow caudoventral lobe, caudodorsal margin with 2 pairs of moderately long processes (Fig. 29); segment X with pair of slender processes of near equal length to 2 dorsal pairs of pygofer caudodorsal processes (Fig. 30); aedeagus symmetrical, moderately long, reaching nearly midlength of ventral paraphysis (Figs.31, 32); ventral paraphysis in dorsal view symmetrical, long, broad basally, narrowed evenly in distal ¾, apex bifid with 2 pair of spines, dorsobasal pair curved, medial pair on dorsolateral margin basad of middle, directly distally (Figs. 31, 32); style in lateral view moderately long, extending to about midlength of paraphysis, apical 1/4 distinctly curved ventrally in lateral view (Fig. 33); connective atypically small; dorsal connective in dorsobasal view V-shape, stem absent (Fig. 34); subgenital plate typical, tuft of long, fine setae apically (Fig.35).   
 Material examined. Holotype male. PNG: Madang province, Markup / Rain Forest, 30-VIII-1987 (87122), Leg P. Grootaert (IRSNB). Paratypes, 1 male, same data as holotype (IRSNB); 1 male, same data as holotype except Yoro / Rain Forest, 22-VIII-1987 (87122) (MLBM); 2 males, PNG, Madang Pr.:Brahman Miss., 6-V.1988 (Sta. 017), leg. J. Van Stalle, I.G. No: 27363 (IRSNB, USU).   
 Etymology. The name of the species is descriptive for similar configuration and length between the processes of the pygofer and segment X.   
 Remarks. From verticalis (Walker) to which it is similar in male genitalia characters, coniunctionis can be distinguished by configuration of the style which is curved ventrally at apical ¼ in lateral view, absence of subapical spine which is present in verticalis and by the more distal position of the medial spines of the ventral paraphysis.
