( Fig. 1 )

Type material: [ CNU] Holotype: Holotype male in a 21x11x 12 mm hexahedral piece of Baltic amber, with the curatorial museum code CNUHHMF006 .

Description: Male: Body elongate, 5.21 mm. Coloration. Dorsum mostly dark brown and partly pale brown.

Head: mostly brown; vertex pale brown; clypeus dark brown; antennae mostly dark brown; first and second antennal segments dark brown; others brown; labium mostly dark brown, first labial segment pale brown except for dark apex. Thorax: pronotum mostly dark brown, posteromedial part pale brown; pronotal collar dark brown except for posterior part pale; scutellum pale brown; hemelytra mostly dark brown; corium mostly dark brown, pale sub-basally; cuneus brown, apical part dark brown; legs mostly brown with dark patches; base and apex of tibia dark brown. Abdomen: brown with dark patches. Surface and Vestiture. Dorsum partly punctate, covered with one type of setae; head with tuft of setae on vertex; frons with erected setae; antennae with short pubescence; pronotum weakly punctate, covered with short pubescence; scutellum impunctate; hemelytra densely covered with one type of pubescence, weakly punctate. Structure. Head: projected dorsally, length superior to first antennal segment length; vertex as long as 1.15 times compound eye width; antennae long; first segment longer than vertex width; second segment cylindrical, as long as 5 times first segment length, less than 2 times third segment length; proportion of first to third antennal segments (fourth missing) 0.5: 0.25: 1.65; labium reaching hind coxae; third labial segment shortest; proportion of first to fourth labial segments 0.78: 0.64: 0.22: 0.82. Thorax: pronotum trapezoidal, pronotal angle rounded; scutellum wider than long; commissure longer than scutellum length; cuneus elongate, inner margin straight; membrane with two cells; legs long, hind femur apex exceeding apex of abdomen.

Abdomen: short, posterior not reaching apex of cuneus. Genitalia: left paramere scythe-shaped; right paramere simple, weakly curved subapically, length subequal to left paramere length, hypophysis sharp.

Measurements (in mm): body length: 5.21; head length 0.61; head width including compound eyes: 1.01; vertex width: 0.37; first antennal segment: 0.51; second antennal segment: 2.52; third antennal segment: 1.65; fourth antennal segment: missing; first labial segment: 0.78; second labial segment: 0.64; third labial segment: 0.22; fourth labial segment: 0.82; pronotal midline length: 0.75; basal pronotal maximal width (straight): 1.38; anterior scutellar width: 1.02; scutellar midline length: 0.85; commissure length: 1.49; outer embolial margin length (straight): 2.80; maximal width across hemelytron: 0.96; hind femur: 2.16; hind tibia: 2.76; hind tarsus: 0.83; tarsal segments of hind leg: 0.20: 0.24: 0.38.

Type locality and stratum: Baltic amber from Baltic Sea Coast, further detailed information unknown; mid- Eocene (ca. 44.1 ± 1.1 Ma) ( Wappler 2005).

Etymology: Named after A. Herczek, Polish plant bug taxonomist, specialist of fossil taxa; a noun in the genitive case.
