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). Male stridulatory file step-like, with about 46 dis- tinct and numerous indistinct stridulatory teeth (Plate 2b)............................... Ph. gracilis Burmeister, 1838

3. 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)

5. Male epiproct wide, lateral margin widened towards apex, with lateral apical corner angular and apical margin wide obtuse................................................................................... Ph. trigonia Ragge, 1957

– Male epiproct not as above.............................................................................. 6

6. 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. Supra-anal plate short tongue-shaped, showing tendency to form three posterior angles (Fig. 73, in Ragge 1956)......................................... Ph. nana Fieber, 1853
