Key to the males of Neotropical Styringomyia   species

(based on the morphology of the gonostylus)

1. Stout spine­like hairs present ( Figs. 10­13 View FIGURES 10 ­ 13 )................................................................... 2

­ Stout spine­like hairs absent ( Figs. 14­17 View FIGURES 14 ­ 17 ).................................................................... 5

2. Gonostylus much longer than broad, bearing two long spine­like hairs; extension I greatly developed, basal in position ( Figs. 10, 11 View FIGURES 10 ­ 13 )........................................................ 3

­ Gonostylus almost as long as broad, bearing at least three short spine­like hairs; exten­ sion I apical in position ( Figs. 12, 13 View FIGURES 10 ­ 13 )........................................................................... 4

3. Four extensions present; apex of extension I broad ( Fig. 10 View FIGURES 10 ­ 13 ) ....... S. mystica   Alexander

­ Only three extensions present; apex of extension I narrowed ( Fig. 11 View FIGURES 10 ­ 13 ) .. S. youngi   sp. n.

4. Extension II short, spine­like hair situated at its apex ( Fig. 12 View FIGURES 10 ­ 13 ) .......... S. atlantica   sp. n.

­ Extension II long, spine­like hair situated at its base ( Fig. 13 View FIGURES 10 ­ 13 ) ..... S. paulista   Alexander

5. Two apical extensions present....................................................................................... 6

­ Only one bifid apical extension present (probably resulting from the fusion of exten­ sion III and IV); anterior margin of gonostylus almost straight; slender hairs in the lat­ eral face concentrated at a protuberance near base of apical extension ( Fig. View FIGURES 14 ­ 17

16)................................................................................................... S. amazonica   sp. n. ­ Three apical extensions present; extension III and IV closely jointed; gonostylus long and slender ( Fig. 17 View FIGURES 14 ­ 17 ) ......................................................................... S. manauara   sp. n.

6. Gonostylus more or less S­shaped; extension III relatively poorly developed; medial face with a long and relatively stout hair near base of extension IV ( Fig. 14 View FIGURES 14 ­ 17 ) ............... ....................................................................................................... S. simplex   Alexander

­ Gonostylus constricted at base; distal part of posterior margin expanded; extension III well developed ( Fig. 15 View FIGURES 14 ­ 17 ) ........................................................................... S. maya   sp. n.
