Type species

Emnicoris silesianus Taszakowski, Kim & Gierlasiński gen. et sp. nov., here designated.

Diagnosis

Distinct from other genera of Deraeocorini by the following combination of characters: body elongate, almost parallel-sided, glossy, mostly brown to fuscous ( Fig. 1A–B View Fig ); head weakly prognathous, frons more or less vertical to clypeus, clypeus projected forwardly ( Fig. 1B View Fig ); vertex narrow, in males 0.3× as long as head width ( Fig. 1A View Fig ); compound eye large ( Fig. 1A View Fig ), in males wider than vertex, ventral margin reaching gula ( Fig. 2A–C View Fig ); antennae thick, shorter than body length ( Fig. 1A View Fig ); first to third antennomeres clavate ( Fig. 1A–B View Fig ); fourth antennomere fusiform; second antennomere shorter than total head width, and shorter than combination of third and fourth antennomeres ( Fig. 1A–B View Fig ); labium short, reaching mesocoxa ( Fig. 1B View Fig ); pronotum large, posterior angle beyond hemelytra lateral margin ( Fig. 1A View Fig ); scutellum small, apically tapering, flat ( Fig. 1A View Fig ); hemelytra glabrous, lateral margin almost straight, very weakly concave ( Fig. 1A View Fig ); claval commissure longer than scutellum length ( Fig. 1A View Fig ); hypocostal lamina with notches forming stridulitrum ( Fig. 2F View Fig ); legs somewhat short and thick ( Fig. 1B View Fig ); all femora thick ( Fig. 1A–B View Fig ); distal part of metafemoral ventral surface with 4–5 ribs forming plectra ( Fig. 2G View Fig ); metatibia thickened ( Fig. 1B View Fig ), third tarsomere longest, subequal to combination of first and second tarsomere ( Fig. 2I View Fig ); left paramere scythe-shaped, 2 × as long as right paramere, hypophysis long and thin, flat apically, sensory lobe weakly projected, covered with setae ( Fig. 1F View Fig ); right paramere rod-shaped, short, hypophysis flat apically ( Fig. 1E View Fig ); endosoma with multiple sclerites, medial sclerite large and broad, lateral sclerite thin ( Fig. 1C–D View Fig ).

Etymology

The genus name is combined as an abbreviation ‘EMN’ of the event ‘Europejskie Miasto Nauki’ (European City of Science), in which a student project was initiated, resulting in the description of this species, and combined with a Greek noun, ‘coris’ (κόρις = bug), gender masculine.

Description

BODY. Elongate and parallel, medium in size (3.6–4.1), glossy.

TEXTURE AND VESTITURE.

HEAD. Weakly prognathous, frons almost vertical to clypeus, clypeus projected forwardly in lateral view ( Figs 1B View Fig , 2A View Fig ); vertex narrow, shorter than single compound eye width ( Figs 1A View Fig , 2B–C View Fig ); compound eye large ( Fig. 2A–C View Fig ), ventral margin reaching gula in lateral view ( Figs 1B View Fig , 2A View Fig ); antennae thick, shorter than body length ( Fig. 1A View Fig ); first to third antennomere clavate; fourth antennomere fusiform; second antennomere shorter than ½ of third antennomere, shorter than combination of third and fourth antennomeres; third antennomere subequal to fourth antennomere ( Fig. 1A–B View Fig ); labium short, reaching midcoxae ( Fig. 1B View Fig ); all labial segments subequal in length ( Fig. 1B View Fig ).

THORAX. Pronotum relatively large ( Fig. 2D View Fig ), posterior angles extending far laterad beyond hemelytra lateral margins, length 0.5–1.0× posterior maximal width ( Fig. 1A View Fig ); scutellum small, apically tapering, width shorter than length, flat in lateral view ( Figs 1A View Fig , 2E View Fig ); hemelytra elongate, lateral margin almost straight, very weakly concave ( Fig. 1A View Fig ); hypocostal lamina with notches forming stridulitrum ( Fig. 2F View Fig ); commissure longer than scutellum length ( Fig. 1A View Fig ); legs somewhat short and thick ( Fig. 1A–B View Fig ); distal half of metafemoral ventral surface with 4–5 ribs forming plectrum ( Fig. 2G View Fig ); third tarsomere longest, subequal to combination of first and second tarsomere ( Figs 1B View Fig , 2H View Fig ).

ABDOMEN. Short, not reaching to apex of cuneus ( Fig. 1B View Fig ).
