Bioacoustics of Araneus breviscapus

Diagnosis. The new species resembles A. wulongensis Song & Zhu, 1992 ( Liu et al. 2019 , figs 9 – 11), but can be distinguished by: 1) dorsal ramus of median apophysis hook-shaped, ventral ramus of median apophysis with blunt tip in A. breviscapus n. sp. ( Fig. 2A, C ) vs. dorsal ramus finger-shaped, ventral ramus with many teeth in A. wulongensis ( Liu et al. 2019 : fig. 10A); 2) conductor with swollen tip in A. breviscapus n. sp. ( Fig. 2A ) vs. with truncated tip in A. wulongensis ( Liu et al. 2019 : fig. 10A); 3) distal end of subterminal apophysis truncated in ventral view in A. breviscapus n. sp. ( Fig. 2F ) vs. with a protuberance at the center in A. wulongensis ( Liu et al. 2019 : fig. 10G); 4) embolus almost L-shaped, embolic lamella almost leaf-like in lateral view in A. breviscapus n. sp. ( Fig. 2E ) vs. embolus C-shaped, embolic lamella finger-shaped in A. wulongensis ( Liu et al. 2019 : fig. 10F); 5) scape straight, wider than long, tip as wide as base in A. breviscapus n. sp. ( Fig. 2G ) vs. S-shaped, much longer than wide, tip expanded distinctly in A. wulongensis ( Liu et al. 2019 : fig. 11A, B); 6) copulatory openings located on the posterio-lateral sides of epigynum in A. breviscapus n. sp. ( Fig. 2H ) vs. located on the anterodorsal side of epigynum in A. wulongensis ( Liu et al. 2019 : fig. 11C, D).
