The stridulatory device of Emnicoris silesianus gen. et sp. nov. and selected Surinamelline taxa

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

The plectrum (520× 50 µm) is located in the distal half of the metafemoral ental surface, and it is formed with four–five slightly arcuate ribs ( Fig. 2G View Fig ). The elongated stridulitrum ( 0.8 mm) is developed on a somewhat arcuate hypocostal lamina. It has the form of a row of dense notches (spaced every 6.25 µm).

The plectrum (270 × 38 µm) is located in the central part of the metafemoral ental surface. It is formed by densely arranged, inclined towards the distal side of the femora, almost recumbent, short (ca 17 µm), thick (ca 3 µm) setae ( Fig. 4A–C View Fig ). The elongated stridulitrum ( 1.12 mm) is developed on a slightly arcuate hypocostal lamina. It has the form of a row of tubercles (ca 9 µm in diameter), having at the apex a hole with a thin and delicate seta protruding from it ( Fig. 4D–F View Fig ).

Glossopeltis conradti Poppius, 1914

The plectrum (0.5 × 0.2 mm) is located in the basal part of the metafemoral ental surface. It is formed by dense, tiny tubercles (ca 1.1–2.2 µm in diameter) ( Fig. 4G–I View Fig ). The stridulitrum is developed on abdominal segments III– V. It is formed by sparsely but evenly distributed (spaced 25–32 µm), slightly inclined, short (ca 12 µm), thick (ca 3,8 µm), curved and pointed setae ( Fig. 4J–M View Fig ).
