Etymology.

The species is named after an ancient population from the southern border of the Carpathians, suggesting its ancient origin, which is revealed by deep genetic and morphological structuring.

Diagnosis.

The new species is distinguished from all other species of the Pedicia staryi group by the following combination of characteristics: all flagellomeres are almost uniformly colored; the abdominal stripe starts from the first segment; the tip of last palpus segment is the same color as the other segments; 9th tergite has a rounded or rarely five angled median lobe, with a notch on the tip or rarely with a small apical emergence.

Description.

Large species of a yellowishorange color (Fig. 6). Males body length is 13-15 mm, (mean 14.2 mm, n=7), wing length 13-14.5 mm (mean =13.9 mm, n=7), antenna 1.6-1.9 mm (mean 1.7, n=5). The head has vertex yellowish orange to dark brown (Fig. 25). Antenna is 13-15 segmented; scape and pedicel are yellowish brown to light brown, flagellomeres are almost uniformly yellowish brown. Scape is cylindrical approximately 2 times longer than width, pedicel wider apically than basally, 1.2-1.5 times longer than width in middle. F1 and f2 fused in some cases, then first segment 2 times longer than width (else 1.2 times), f2-f6 approximately oval, f7-f12 fusiform, last one or two segments elongated or orb-like. All flagellomeres with 4-6 black bristles, about half as long as the flagellomeres. Palpus 5-segmented; 2-4 palpomeres dark brown, the ventral parts lighter and more membranous than dorsal parts; the basal part of the last palpomere is light brown, dark brown at tip. Rostrum is slightly darker than vertex, margin of the labellum brown. Lateral parts of the thorax are yellowish orange, only the front margin of the katepisternum is light brown in some cases. Scutum is dark orange, with two longitudinal hair lines. Center of postnotum is yellowish orange, lateral margin is dark orange to light brown. Wing venation is yellowish brown (Fig. 6). Pterostigma is light orange, less visible. Small spots are present at Sc2 and around R2, spots are not visible around r–m and base of Rs, only the venation is slightly darkener. Halters have yellowish stem and orange knob. The legs femora is light brown and tibiae yellowish brown, and both are black at tips. Tarsi are light brown to dark brown. Dorsally on the abdomen is a pale to dark brown longitudinal stripe starting from the first abdominal segment. The 7th and 8th sternites and tergites are light brown. Male terminalia is considerably broad (Figs 8, 9). The 9th tergite is generally darker than the remaining parts of the hypopygium. Posterior margin of 9th tergite has a rounded or rarely five angled median lobe, with a notch on the tip or rarely with a small apical emergence. Gonocoxite is stout, cylindrical, and truncated at distal end (Fig. 7). Flat spoon-like extension is present at the distal end of gonocoxite ventrally, directed inwardly, covered densely in short black spinules and partly hides the gonostylus in ventral view. Gonostylus is subterminal, inserted laterally at distal inner side of the gonocoxite, forming a nearly right angle with the latter. Gonostylus is generally quadrangular in dorsal or ventral views, with 7-11 strong black spines mostly situated at outer distal margin and with short slender projection at lower (caudal) margin distally, which is less conspicuous in some cases. Interbase simple, broadened and rounded distally.

Female is unknown.
