Description. Body length: ♂♂ 6.8–8.9 mm (holotype 6.9 mm), ♀♀ 7.6–9.4 mm.

Male (holotype, Fig. 55 View Figs 52–55 ). Body yellowish orange, apices of mandibles black, antennomeres I and II yellowish, rest of antennomeres black, extreme lateral margin of epipleura in basal half black. Femora yellowish, tibiae and tarsi black, last two tarsomeres and claws dark brown. Last ventrite posteriorly with two small incisions ( Fig. 26 View Figs 19–26 ).

Interocular space 1.5 times as wide as transverse diameter of eye. Antennae 0.9 times as long as body, length ratio of antennomeres I to XI equals 15-5-7-14-14-15-15-15-15-13-15. Pronotum 1.40 times as broad as long. Elytra glabrous, 1.75 times as long as wide (measured at humeral calli), 0.75 times as long as body. Length ratio of metatarsomeres I–IV equals 12-6-4-9.

Aedeagus: dorsal side apically with symmetrical triangular incision; ventral side with very long thin incision medially ( Fig. 18 View Figs 15–18 ).

Female. Last ventrite with wide concavity at apex, lateral sides slightly concave ( Fig. 33 View Figs 27–33 ), pygidium with simple sharp triangular tip ( Fig. 40 View Figs 34–40 ). Spermatheca: nodulus large, globular, cornu regularly rounded, slightly narrower than nodulus ( Fig. 47 View Figs 41–47 ).

Variability. Ratio width/length of pronotum varies between 1.40–1.55.

Differential diagnosis. Hesperopenna zofka sp. nov. is very similar to H. tibialis . Both species share a similar structure of aedeagus with a very long basal orifice longer than the proximal part of aedeagus, bicolorous legs and glabrous elytra. Hesperopenna zofka sp. nov. differs from H. tibialis in black antennae with first two antennomeres yellow (completely yellow antennae in H. tibialis ) and in epipleura always with black extreme lateral margin in the basal half (epipleura completely yellow or at most with brownish extreme lateral margin in H. tibialis ). Males can be distinguished by the long thin incision on the ventral side of aedeagus which is placed medially in H. zofka sp. nov. while placed on the right side in H. tibialis ( Figs 13 View Figs 11–14 , 18 View Figs 15–18 ). Females of both species can be separated by the shape of pygidium: apex simply triangular in H. zofka sp. nov. while distinctly pointed in H. tibialis ( Figs 36, 40 View Figs 34–40 ).
