Key to species of Phaneroptera from China 1. Lateral lobe of pronotum distinct longer than high............................................................ 2 – Lateral lobe of pronotum as high as long or slightly higher than long............................................. 3 2. Size much smaller (length of tegmen<10mm, length of hind femur<15mm). Male stridulatory file “S”-shaped, with about 40 stridulatory teeth (Plate 1b)............................................................ Ph. brevicauda sp. nov. – Size much larger (length of tegmen<18mm, length of hind femur<17mm).

Distal part of male cerci bent vertically, with the apex directed upwards........................................... 4 – Male cerci not as above, only curved in the horizontal plane, with the apex not directed upwards....................... 5 4. Male subgenital plate very broad with spreading lobes (Plate 2i; Fig. 37, in Ragge 1956). Male supra-anal plate wider than long (Plate 2l; Fig. 80, in Ragge 1956)...................................................... Ph. falcata (Poda, 1761) – Male subgenital plate comparatively slender with almost contiguous lobes (Fig. 40, in Ragge 1956).

Male stridulatory organ large, almost as broad as long (Fig. 84, in Ragge 1956). Antennae usually black, sometimes with widely spaced, narrow, white bands. Supra-anal plate quadrate, with concave margins (Plate 3f; Fig. 82, in Ragge 1956).................................................................. Ph. nigroantennata Brunner von Wattenwyl, 1878 – Male stridulatory organ relatively smaller. Antennae unicolorous.
