( Fig. 1 ) Type material: [ CNU ] Holotype : Female in a 14×7× 6 mm elongate light-brown piece of amber. Dorsal, lateral and ventral surfaces flat. Amber internally with small bubbles and internal fractures. No syninclusions. Collection code CNUHHMF006. Description: Female : Body elongate oval, length 4.23 mm . Coloration . Mostly dark brown. Head: mostly dark brown; antennae brown with dark brown parts; first antennomere brown with dark base and apex; second antennomere mostly pale brown, dark brown subapically; third antennomere pale brown with dark apex; fourth antennomere mostly brown with dark apex; labium mostly brown, apex of fourth labial segment dark brown. Thorax: pronotum mostly dark brown, posterior margin paler; pronotal collar entirely pale brown; scutellum mostly dark brown, mesoscutum dark brown, scutellum paler; hemelytron mostly dark brown, posterior part of clavus dark brown; posterior part of corium with dark brown markings; embolial margin brown; cuneus paler brown, inner and apical parts with dark spots; membrane subhyaline, veins dark brown; legs mostly pale brown with dark small markings and annulations; fore and mid femur pale brown with small dark markings; hind femur brown with dark annulation in middle part; tibia mostly pale brown; tarsus brown, third tarsomere dark brown. Abdomen: mostly dark brown in ventral view. Surface and vestiture . Body glossy, partly punctate, densely covered with short setae; head impunctate, covered with short setae; thorax mostly glossy, partly punctate, covered with dense setae; pronotum glossy, densely covered with setae; callosite strongly punctate; scutellum glossy, punctate, covered with dense setae, mesoscutum clearly punctate, scutellum weakly punctate; hemelytra glossy, punctate, covered with dense setae; embolium area impunctate; legs covered with setae and armed with spines; femur densely covered with short setae; tibia covered with setae and armed with spines; abdomen covered with long setae. Structure . Head: prognathous, wider than long, shorter than pronotal midline, longer than first antennomere length; vertex wide, wider than compound eye width; antennae generally linear, shorter than body length; second antennomere clearly thicker than third, fourth antennomere; third antennomere shorter than fourth antennomere; labium reaching hind coxae. Thorax: pronotum trapezoidal, anterior width shorter than head width, pronotal midline length longer than 1/2 of basal width, slightly longer than scutellum midline; pronotal collar subequal to first antennomere diameter; scutellum large, strongly tumid; commissure length subequal to scutellum midline length; lateral margin of hemelytra slightly rounded; cuneus equilateral triangular, inner margin slightly sinuate; legs somewhat thickened; combined length of hind femur and hind tibia shorter than body length; tarsus subequal to 1/3 tibia; third tarsomere longest, shorter than combined lengths of first and second tarsomeres. Abdomen: elongate, reaching apex of cuneus. Measurements (in mm): body length: 4.23; head length 0.51; head width including compound eyes: 0.75; vertex width: 0.31; first antennomere length: 0.48; second antennomere length: 1.32; third antennomere length: 0.56; fourth antennomere length: 0.78; first labial segment: 0.48; second labial segment: 0.41; third labial segment: 0.52; fourth labial segment: 0.51; pronotal midline length: 0.81; basal pronotal maximal width (straight): 1.37; anterior scutellar width: 0.71; scutellar midline length: 0.75; commissure length: 0.78; outer embolial margin length (straight): 2.18; hindleg (femur: tibia: tarsus): 1.21: 1.45: 0.43. Type locality and stratum: Unknown locality on the Baltic Sea Coast , Poland or Russia , mid-Eocene (ca. 44.1±1.1 Ma) ( Wappler, 2005 ) . Etymology: Named after Aleksander Herczek, a well-known mirid taxonomist, on the occasion of his 70 th birthday; noun in genitive case.
