Goriresina fungifora

description: Goriresina fungifora, new species   
 Type material. Holotype female SIZK L-813, Voronki, Rovno amber, late Eocene (Figs 1, 2).   
 Preservation status. The inclusion is in a large, flat and clear piece of amber. Legs are entirely complete, only the apex of the right mesofemur and the base of the right mesotibia being damaged. Most dorsal surface of the right elytron is not visible. Probably as a result of microbial decay during the embedding of the beetle in the resin the left side of its body is densely covered with milky coating and is thus insufficiently contrasting.   
 Syninclusions. Carabidae (Lebiini), leg of Sciaroidea, legs of Tipuloidea, fragments of two Insecta incertae sedis (Diptera or Hymenoptera), two Collembola (Entomobryomorpha and Symphypleona), and Ophiocordyceps sp. (Fungi: Ascomycota).   
 Description. See diagnose and description of the monotypic genus above.   
TL— 10.7 mm.  
Colour could be identified only presumably. Head and pronotum dark, apparently with metallic tinge; at least antennomeres 1–3, as well as visible palpomeres with metallic tinge; metepisternum, metepimeron and at least abdominal sternite 1 seem to be metallic brown-bronze; legs dark, probably with metallic tinge (Fig. 4); elytra black-grey, possibly with bronze lustre.  
HL = 1.9 mm; TE = 1.2 mm, LE = 1.4 mm; MP2L:MP3L:MP4L = 1.6:1.0:1.25; 3rd labial palpomere 2.1 times longer than the 4th one; 3rd antennomere with three short setae except apical ones, 5th antennomere with two visible, short, apical setae; AN2L:AN3L:AN4L:AN5L:AN6L:AN11L = 1.0:3.7:2.0:2.8:2.5:1.75.  
PL = 2.4 mm, DL/PL = 0.54 (NB: the pronotum is completely visible only in the left lateral view; only a small portion of the apical lobe and disc are discernible in the right dorsolateral view, its most part remaining invisible).  
Macropterous, apex of right wing (Fig. 3) and a short portion of costal vein of right wing with regular transverse notches (Fig. 13), all well-visible.  
Elytra not fused, EL = 6.75 mm, EW (only left elytron) = 2 mm, EL/EW = 1.69, elytral sculpture formed by numerous small hexagonal pits. Series umbilicata with at least 11 setae: six (4+1+1) in humeral group and five (2+3) in middle group. Elytral pattern probably represented by an apical portion of humeral spot, a slightly sinuate, transverse medial fascia with an extended and downward directed apical portion, and oval apical spot (Fig. 17).  
Fore, middle and hind femora with five, three and four visible setae along bottom margin, respectively; apical portion of posterior margin of tibiae, especially on fore legs, with a dense row of setae, all tibiae each with two spurs (Figs 3, 15).  
 Etymology. Named after the Ophiocordyceps sp. synnema on the right eye of the holotype (Fig. 8).   
 Differential diagnosis. The new species is easily distinguished from P. groehni and P. cassolai, both described from Baltic amber, by the shape of the labrum with six submarginal setae (latero-basal setae very long) and two apical teeth with notch between them (Figs 5, 6, 10 vs figs 7, 17 in Wiesner et al. 2017), by the more globular pronotum, by the apicad converging elytra as well as by the small sharp sutural spine (Figs 11, 17 vs figs 12, 13 in Wiesner et al. 2017). Additionally, the new species is well distinct from P. groehni by its smaller size, the less furrowed head, and the dense punctuation and sparse pubescence of the humeral area of the elytra (Fig. 12). Besides this, the new species differs from P. cassolai by the larger size, longer labrum (Fig. 5, 6, 10 vs fig. 17 in Wiesner et al. 2017), densely setose 3 rd labial palpomere, and clearly shorter 4 th labial palpomere (Fig. 7 vs fig. 19 in Wiesner et al. 2017).
