description: Updated key to Philomyceta species
The key is based on that by SCHILLHAMMER (2014), with P. biwenxuani sp. nov. included. The unidentified species from Xizang: Nielamu County is very similar to P. spoerii and P. kleebergi which can be only distinguished by male genitalia (see couplet 10) and is hence not included in the key.
1 Apical margin of elytra narrowly but sharply delimited by yellowish coloration, at least in lateral half. ....... 2
‒ Elytra entirely dark, metallic bluish to partly greenish in color. .................................................................... 6
2 Antennomere VIII creamy white; first three visible abdominal tergites with transverse basal depression and pairs of subparallel to oblique basal accessory lines; elytra without distinct longitudinal carinae. .... 3
‒ Antennomere VIII dark; first five visible abdominal tergites with transverse basal depression, first four visible tergites with pairs of subparallel to oblique basal accessory lines; elytra with distinct longitudinal carinae. .................................................................... 4
3 Antennomere XI creamy white; elytra entirely dark except for narrowly yellowish posterior margin; first three visible abdominal tergites black. ....................... ............................................... P. biwenxuani sp. nov.
‒ Antennal segment XI dark; elytra with basal fifth reddish; first three visible abdominal tergites reddish. .................................... P. semicyanea (Fauvel, 1895)
4 Pronotum reddish, abdominal segment VIII yellowish. .......................... P. costata (Fauvel, 1895)
‒ Pronotum blackish, abdominal segment VIII with basal two thirds yellowish and apical third black. ............. 5
5 Abdominal segment III reddish, segments IV and V reddish with medio-posterior portion darkened. ........ .......................... P. asperipennis Schillhammer, 2012
‒ Abdominal segment III–V blackish. .......................... .............................. P. taungmae Schillhammer, 2018
6 First three visible abdominal tergites with transverse basal depression and pair of distinct subparallel to very slightly oblique carinae; tergite VI with much weaker depression and either without carinae or carinae very indistinct and short; posterior margin of tergite VII broadly bright reddish, occupying up to one fourth of tergite length (from basal line to posterior margin); legs always entirely black, rarely tibiae dark brown. .................................................................................. 7
‒ First four visible tergites with distinct transverse basal depression and pair of distinct and markedly oblique carinae; posterior margin of tergite VII very narrowly obscurely reddish, if broadly bright reddish, then legs entirely reddish. ....................................................... 8
7 Eyes larger, tempora less than 1.3 times as long as eyes, median lobe of aedeagus with apex simple. ...... ............................................ P. affinis Cameron, 1944
‒ Eyes smaller, tempora at least 1.4 times as long as eyes, median lobe of aedeagus with apex deeply bifurcate. ............ P. schawalleri Schillhammer, 2012

‒ Legs black. .............................................................. 9
9 Eyes larger, tempora about 1.6 times as long as eyes in males, less than 1.5 times in females; paramere with distinctly broadened apex, aedeagus: fig. 5 in SCHILLHAMMER (2014). ................................................ .................................. P. kucerai Schillhammer, 2014
‒ Eyes smaller, tempora more than 1.7 times as long as eyes in males, at least 1.6 times in females; paramere without broadened apex. ....................................... 10
10 Paramere more asymmetric with area of sensory peg setae longer, aedeagus: fig. 13 in SCHILLHAMMER (2012). ..................... P. spoerrii Schillhammer, 2012
‒ Paramere less asymmetric with area of sensory peg setae shorter, aedeagus: fig. 12 in SCHILLHAMMER (2012). ................... P. kleebergi Schillhammer, 2012
