| Summary: | Key for species of Pteroloma Gyllenhal, 1827 of China and adjacent countries The key is modified from LAFER (2002). 1 Elytra almost round (1.2 times as long as wide), with very wide epipleural keel (RŮŽIČKA & SCHNEIDER 1995: 113, Fig. 1) (Russia: Primorye region: south of Sikhote Alin mts). P. plutenkoi (Růžička & Schneider, 1995) – Elytra more oval (1.35–1.50 times as long as wide), with narrow epipleural keel (LAFER 2002: 52, Fig. 1). 2 2 Body yellowish (becoming light brown in dead specimens); antenna distinctly bicolorous, with antennomeres 1, 2 and 11 yellow and the others black (LAFER 2002: 52, Fig. 1); legs bicolorous, yellow with black tibia and apical part of femora; lateral margin of elytra serrate to three fourths of its length; aedeagus regularly rounded toward apex in lateral view, paramera short, not exceeding half of the length of median lobe (LAFER 2002: 53, Fig. 2C); apex of aedeagus wide, quadrate, symmetrical, very slightly constricted subapically, without median translucent ‘window’ in dorsal view (LAFER 2002: 53, Fig. 2D) (Russia: south-western Primorye region). P. nigromontanum Lafer, 2002 – Body dark brown to black in mature specimens (pale brown in teneral adults); antenna and legs uniformly concolorous; lateral margin of elytra serrate only to 1/3 of its length; aedeagus different, but paramera longer than half of the median lobe (LAFER 2002: 53, Figs. 2A,E). 3 3 Apex of aedeagus very narrow, forming distinctly asymmetrical spike in dorsal view (LAFER 2002: 53, Fig. 2B), straight in lateral view (LAFER 2002: 53, Fig. 2A) (Russia: Irkutsk region to Sakhalin, Mongolia, Japan: Hokkaido). P. sibiricum Székessy, 1935 – Apex of aedeagus wider, subquadrate, slightly asymmetrical, distinctly constricted subapically, with medial translucent ‘window’ in dorsal view (LAFER 2002: 53, Fig. 2F), sinuate in lateral view (LAFER 2002: 53, Fig. 2E) (forest zone across the Palaearctic Region).
