Ordo: Hemiptera
Familia: Reduviidae
Name
Renicoris Wang & Chen & Zhao & Cai, 2023 gen. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Type species
Renicoris robustus sp. nov.
Type locality
China, Yunnan, Lvchun, Huanglian Mountain.
Diagnosis
Renicoris gen. nov. resembles Chenicoris Chen & Cai, 2020 in the structure of the head and the male genitalia (Figs 1–3). However, in the new genus, the pronotum is trapezoidal and its median transversal constriction is indistinct (Figs 1, 2); the posterior pronotal lobe is not enlarged, the lateral pronotal angle is spine-shaped; the lateral margin of pronotum is straight (Figs 1, 2); the abdomen is rhomboid, and the fourth to sixth connexival segments of the abdomen are produced laterally (Fig. 1); the median pygophore process is bifid with acute angles (Fig. 3a, b) (vs. in Chenicoris, the pronotum is not trapezoidal due to its median transversal strong constriction; the posterior pronotal lobe is much enlarged and the lateral pronotal angle is rounded; the lateral margin of pronotum is distinctly constricted in the middle; the abdomen is not rhomboid, the fourth to sixth connexival segments of the abdomen are produced laterally, especially the lateral angle of the fifth segment which is dilated and round; the median pygophore process is absent). The genera morphologically related to the new genus can be separated using the following key.
Generic character
Body somewhat robust (Figs 1, 2). Head shorter than pronotum, with a small round tubercle behind base of each antennal tubercle (Figs 1a, 2a); eyes large and protruded laterally (Figs 1, 2a–c); ocelli elevated; anteocular part slightly longer than postocular part, transversely constricted between eyes; postocular part posteriorly narrower (Figs 1, 2a–c); first antennal segment nearly as long as head and pronotum together in length; first rostral segment longest and extending to middle of eyes (Fig. 2b). Pronotum dorsally slightly flat, somewhat anteriorly declining, medially with indistinct transversal constriction; lateral margin nearly straight; anterior angle round; anterior pronotal lobe 1/2 as long as posterior lobe; middle part of posterior lobe faintly bulgy, two sides with lateral sulci; lateral pronotal angles produced laterally, short spine-shaped, with round protuberance behind it; posterior and posterolateral margins nearly straight; posterior angle round; scutellum subtriangular with Y-shaped ridge (Figs 1, 2a–c). Legs thick and robust, fore legs somewhat thickened (Figs 1, 2). Fore wing with inner cell wider than outer cell at base. Fourth to sixth connexival segments of abdomen laterally slightly rhombus-shaped dilated.
Distribution
China (Yunnan).
Etymology
The genus is named after the Chinese entomologist Shu-Zhi Ren (Nankai University, Tianjin, China), for her great contribution to the taxonomy of Chinese Heteroptera. The Greek noun coris means “bug”. Gender masculine.
