(Figs 4 a, 4b)
Description. Head: Metope 2.5x as long as wide, weakly expanding in middle then narrowing before joining metoclypeal suture. Dorsal margin of metope almost straight. Median keel distinct, running through metope and metoclypeal suture. Metoclypeal suture elongate, triangular. Lateral keels present and distinct. In lateral view metope arcuately convex, but in central part rather straight, metoclypeal suture almost straight (Figs 1 a, 1b). Eye black, round, ocelli present. Coryphe almost twice as wide as long, anterior margin convex and weakly angular, posterior margin distinctly arcuately concave (Fig. 1 c).
Pronotum and mesonotum: Pronotum bluntly rounded, distinctly concave. Mesonotum weakly convex, with three parallel keels: anterior part of median keel joined to two slanting lines converging almost at right angle and thus forming an arrow-shaped structure. Both edges of arrow joined to two lateral keels.
Fore wings: Clavus elongate, as long as 2/3 of whole wing length. Two longitudinal veins on clavus converge at 1/3 of their length. Two transverse veins present on the clavus. Radius bifurcate (R2) after cubitus (Cu2). Costal membrane with ten transverse veins, costal cell with two transverse veins. Stigma round and black, covering 1/3 of cell, partially entering apical fragment of costal cell. Five short parallel veinlets arise from stigma, four brown cells located among those veinlets and separated from the black stigma with a yellow line. Nineteen apical cells present at apex of fore wing (Fig. 1 d). Hind wings well developed, as long as 4/5 of fore wings’ length.
Legs. Tibia triangular in lateral view with concave ventral side. Lateral margin with four lateral spines present, three of which are distinct and 1 weakly visible. Lateral margin cross-striated and covered with small, barely visible bristles.
Coloration. General coloration yellowish-brown, metope with keels distinctly red. Larteral margins of tergites of abdomen brown. Wings hyaline with brown veins. Femur coloration light brown with dark brown base, tibia coloration uniformly light brown, spines brown, darker than tibia.
Male genitalia: Pygofer with hind margin strongly convex. Anal tube elongate, weakly narrowed basally and enlarged apically in dorsal view. Anal column about 0.33x as long as anal tube (Fig. 1 f). Style almost triangular with caudo-dorsal angle obtuse. Apical tooth of style wide and folded, bearing subapical tooth on inner side (Fig. 1 g). Aedeagus narrow, falcate in lateral view. Ventral phallobase reaching half length of aedeagus. Each dorsolateral phallobase lobe with one long, narrow, semicircular apical process bearing small, abundant denticles. Subapical process horn-shaped. Dorsal surface of phallobase with bird-head-shaped process medially. Apical aedeagal process leaf-shaped with two barely visible curved apical teeth (Fig. 1 e).
Remarks. Exphora stroinskii sp. n. is similar to other species externally, but can be distinguished from related by the pattern of black round stigma, metope lacking of brown stripes, long anal tube, shape of style, aedeagus and its processes (see the key above).

Exphora constanti Junkiert & Walczak, sp. n. (Figs 4 c, 4d)
Description. Head: Metope twice as long as wide, distinctly enlarging in middle where it becomes arcuately convex then narrowing to metoclypeal suture. Upper part of metope weakly (but distinctly) concave. Median keel distinct, running through metope and metoclypeal suture. Metoclypeal suture elongate, triangular, upper margins weakly arcuately curved, lateral keels present and distinct. In lateral view metope distinctly convex, whereas metoclypeal suture almost straight. Eye black, round, ocelli present (Figs 2 a, 2b). Coryphe almost twice as wide as long, anterior margin convex and weakly angular, posterior margin distinctly arcuately concave (Fig. 2 c).
Pronotum and mesonotum: Pronotum bluntly rounded, distinctly concave. Mesonotum weakly convex, with 3 parallel keels: anterior part of median keel joined to two slanting lines converging almost at right angle and thus forming an arrow-shaped structure. Both edges of arrow joined to two lateral keels.
Fore wings: Clavus elongate, as long as 2/3 of the whole wing length. Two longitudinal veins on clavus converge at 1/3 of their length. Two transverse veins present on clavus. Radius bifurcate (R 2) after cubitus (Cu 2). Costal membrane with nine transverse veins, costal cell with three transverse veins. Stigma round and black, covering 1/3 of cell, partially entering apical fragment of the costal cell. 4 short parallel veinlets arise from stigma, three brown cells located among those veinlets. Nineteen apical cells present at apex of fore wing (Fig. 2 d). Hind wings well developed, as long as 4/5 of the wings’ length.
Legs: Tibia triangular in lateral view with concave ventral side. Lateral margin with four lateral spines present, three of which are distinct and 1 weakly visible. Lateral margin cross-striated and covered with small, barely visible bristles.
Coloration. General coloration yellowish-brown, metope with keels distinctly red, between lateral and median keels brown stripes passing along the metope. Larteral margins of tergites of abdomen brown. Wings hialine with brown veins. Femur and tibia coloration uniform–yellowish-brown, spines brown, darker than tibia.
Male genitalia: Pygofer with hind margin convex. Anal tube elongate, enlarged apically in dorsal view. Anal column long, about 0.4x as long as anal tube (Fig. 2 f). Style almost triangular with caudo-dorsal angle obtuse. Apical tooth of style folded, bearing subapical tooth on its inner side (Fig. 2 g). Aedeagus falcate in lateral view. Ventral phallobase reaching almost half length of aedeagus. Each dorso-lateral lobe with two processes: apical one, slightly curved, narrow, twice longer than subapical, hornshaped. Hind margin with a few weakly visible denticles. Adeagus with two distinct semicilcular bulges placed ventraly. Dorsal surface of phallobase with blunt process with week concavity placed distally (Fig. 2 e).
Remarks. Exphora constanti sp. n. is similar to other species externally, but can be distinguished from related by distinct brown stripes on metope, shape of pygofer, anal tube, style and aedeagus (see the key above).
