Key for the Costa Rican species of Physocephala Schiner, 1861

1 Antennal groove completely and densely silver dusted (figure 27); haltere completely black; frons black (figure 27) ....................................................................................................... lugubris ( Macquart, 1835) - Antennal groove not or only inconspicuously dusted (figure 30); haltere at least partly yellow (figure 29); frons partly yellow in many species (figure 30) ........................................................................................ 2 2 Mesopleuron without pubescent stripe (figure 9); knob of haltere completely dark black ....................... 3 - Mesopleuron with pubescent stripe; knob of haltere yellow or brown, at maximum a brownish darkening at tip ........................................................................................................................................................... 4 3 Gena uniformly dark (figure 10); antenna and proboscis at least partly darkened (figure 10); posterior dorsal corner of the katepisternum at most slightly dusted; tip of the female abdomen as figure 11: tergite 5 less curved and syntergite 6 shorter.................................................................... carbonaria ( Bigot, 1887) - Gena lighter in the middle (figure 17); antenna and proboscis completely orange (figure 17); posterior dorsal corner of the katepisternum obviously dusted; tip of the female abdomen as figure 18: tergite 5 strongly curved and syntergite 6 quite long .................................................................. herrerai spec. nov. The following four species are very similar and can be separated only by colouration characters-future research has to test if these are good species or only colour forms of one variable species.
