description: Key to the species of <i>Philorhizus</i> Hope from Greece 1 Pronotum very narrow (ratio width/length 1.21-.36), with posterior angles obtuse and angled strongly forward (at about the length of antennomere 2), and therefore its base laterally strongly rounded toward posterior angles. Tempora long, almost as long as eye diameter, or somewhat shorter, almost rectilinearly narrowed, distinctly set off against neck (see Figs 2, 3 in Wrase, 2005). Two species from the Peloponnese (Aroania and Taygetos Mts., with strongly reduced hindwings, elytra with completely rounded humeri......... 2 – Pronotum wider (ratio width/length &lt;1.21), with posterior angles less obtuse and only weakly angled forward, its base weakly rounded laterally toward posterior angles (see Figs 2, 15, 16, 17 in Sciaky, 1991). Tempora short, ± distinctly curved to the neck. Macropterus or micropterous species with a wider distribution....................................................................................... 3 2. Unicolorous pale yellowish red, only dorsal side of head and an indistinct macula in posterior half of elytra rusty red. Tempora almost as long as eye diameter. Alpine regions of northern mountains in Peloponnese...................................................................................... <b> <i>Ph. alpinus</i> (Meschnigg, 1934)</b> – Head (more or less dark reddish) piceous, elytra with a distinct, wide, dark transverse fascia at apical half extending forward along suture, omitting a large, testaceous semicircular or square area around sutural angle, abdomen dark. Tempora somewhat shorter. Alpine regions of Taygetos Mountains in Peloponnese.................................................................. <b> <i>Ph. marggii</i> nov. sp.</b> 3. Strongly brachypterous, elytra very short (ratio length/width 1.22-1.30), with completely rounded humeri. Elytral basal third testaceous. Small species (2.8- 3.4 mm). Southern Greek mainland (Parnassos) and northern mountains in Peloponnese............................................................ <b> <i>Ph. lompei</i> Wrase, 2005</b> – Macropterus or micropterous species, elytra long (ratio length/width&gt;1.40), in both cases elytral humeri distinctly developed......................................... 4 4. Large species (3.7-4.7 mm). Macropterous, elytral humeri dark brown. From the Canaries to the Near East................ <b> <i>Ph. quadrisignatus</i> (Dejean, 1825)</b> – Smaller species (2.5-3.5 mm). Macropterous to micropterous, elytral humeri always light.................................................................................................5 5. Elytra pale yellowish, as a rule with darkened suture. From western Mediterranean area to Asia Minor and Caucasus.................................................................................................................. <b> <i>Ph. melanocephalus</i> (Dejean, 1825)</b> – Elytra always with dark pattern: dark transverse fascia in middle or at least a wide band along parts of suture and posterior part of lateral margin........... 6 6. Elytra on average more slender (ratio length/width 1.51-1.57, Ø 1.54), almost parallel-sided, with narrow transverse dark fascia, dark pattern more cross-like, the central square-like macula often without connection to the lateral longitudinal darkenings. Pronotum usually darkened in middle. Internal sac of median lobe of aedeagus with tubular, long-winding structure, apically darkened by longer and denser microspines. Median lobe with longer apex (see Fig. 22 in Sciaky, 1991). From western Mediterranean area, Asia Minor, Middle East to Middle Asia. On the Balkan Peninsula with ssp. <i>crucifer</i>................................ <b> <i>Ph. crucifer</i> (Lucas, 1846)</b> – Elytra on average wider (ratio length/width 1.41-1.54, Ø 1.46) and slightly widened apically, with very variable colour pattern, transverse dark fascia usually very wide, but sometimes not distinct, disappearing. Pronotum rusty red, often darkened on disc. Internal sac of median lobe of aedeagus with 2 subparallel fields of denticles. Apex of median lobe shorter and rounded (see Fig. 21 in Sciaky, 1991). Whole of Europe to Near East...................................................... <b> <i>Ph. notatus</i> (Stephens, 1827)</b>
