Key for the identification of the species of Micropygomyia (Coquilletimyia) with male characters

1 Epandrial lobe as long or longer than gonocoxite............................................................. 2

- Epandrial lobe shorter than gonocoxite.................................................................... 6

2 Aedeagal ducts with the preapical portion shaped like the head of a lance, i.e., lanceolate............................ 3

- Aedeagal ducts not modified, i.e., the preapical portion simple, slender..... Micropygomyia (Coquilletimyia) nahua sp. nov.

3 Gonocoxite basal tuft with more than five setae; gonostyle with the two basal spines nearly at the same level; paramere strongly humpbacked basally, with the arm inflated in the apical third giving the appearance of a duck head in flight......................................................................... Micropygomyia (Coquilletimyia) vindicator

- Gonocoxite basal tuft with five or less setae; gonostyle with the two basal spines at different levels; paramere not strongly humpbacked basally, with the arm slender................................................................... 4

4 Aedeagal ducts with the apical filament beyond the inflated portion not longer than the inflated portion; paramere with a slim waist lacking setae................................................... Micropygomyia (Coquilletimyia) oppidana

- Aedeagal ducts with the apical filament beyond the inflated portion longer than the inflated portion; paramere arm with a regular width............................................................................................ 5

5 Antenna with ascoids of flagellomere II extending beyond end of flagellomere; flagellomere I about 2.2 as long as labrum; paramere with the arm longer than the humpback basal area. Micropygomyia (Coquilletimyia) apache - Antenna with ascoids of flagellomere II short, not reaching the end of flagellomere; flagellomere I about 1.3 as long as labrum; paramere with the

arm as long as its humpback basal area..................................... Micropygomyia (Coquilletimyia) vexator 6 Gonocoxite basal tuft of 4 robust setae; aedeagal ducts lanceolate........................................................................................... Micropygomyia (Coquilletimyia) stewarti ( Mangabeira & Galindo, 1944) - Gonocoxite basal tuft with more than 4 setae; aedeagal ducts lanceolate or simple................................... 7

7 Aedeagal ducts lanceolate; gonostyle with the median spine situated in the middle between the basal and the apical pairs................................................. Micropygomyia (Coquilletimyia) californica ( Fairchild & Hertig, 1957)

- Aedeagal ducts simple, tips not expanded; gonostyle with the median spine situated proximally to the basal pair than to the apical pair............................................. Micropygomyia (Coquilletimyia) chiapanensis ( Dampf, 1947)
