Microledrida, Fowler, 1904

Key to Microledrida View in CoL species (males) (in part based on Kramer, 1983)

1. Vertex green with three incomplete red stripes ( Fig. 15A View FIGURE 15 )...................................... Microledrida virida View in CoL

– Vertex mainly brown or orange-brown (e.g. Fig. 2C View FIGURE 2 ), without distinctive pale green and red colouration................ 2

2. Face unicolourous, entirely darkly mottled, shaded with brownish, or all pale (e.g., Fig. 10C View FIGURE 10 )........................ 3

– Face with middle portion transversely pale, upper and (to a lesser extent) lower portions darker ( Figs. 9C View FIGURE 9 , 14C View FIGURE 14 ).......... 5

3. Anal tube strongly asymmetrical: right lateral side apically with a distinctive anteroventrally directed appendage, left lateral side apically somewhat downcurved (fig. 11A-B).......................................... Microledrida asperata View in CoL

– Anal tube symmetrical, right lateral side without distinctive anteroventrally directed appendage....................... 4

4. Anal tube in left lateral view comparatively short, its apical portion broadly blunt ( Kramer 1983, fig. 55); phallotheca in lateral view with distally projecting process on ventral margin......................................... Microledrida flava View in CoL

– Anal tube in left lateral view elongated, its apical portion irregularly oval ( Kramer 1983, fig. 68); phallotheca in lateral view without distally projecting process on ventral margin......................................... Microledrida fuscata View in CoL

5. Phallotheca with two relatively slender apical spines and one thicker spine near the middle on the left lateral or ventral side 6

– Phallotheca with two relatively slender apical spines, lacking a thicker spine near the middle ( Caldwell & Martorell 1951, fig. 3a); Puerto Rico, Dominican Republic...................................................... Microledrida arida View in CoL

6. Vertex with irregular orange stripes ( Fig. 14A View FIGURE 14 ), anal tube relatively long, in lateral view apically deflexed ( Kramer 1983, fig. 52), strong spine near the middle of phallotheca positioned at its left lateral side ( Kramer 1983, fig. 53); USA: Texas; Mexico: Nuevo León ........................................................................... Microledrida olor View in CoL

– Vertex without orange stripes ( Fig. 2C View FIGURE 2 ), anal tube short, in lateral view with a straight apex ( Fig. 5C View FIGURE 5 ), strong spine near the middle of phallotheca positioned at its ventral side ( Figs. 6B View FIGURE 6 , 7B View FIGURE 7 ); Curaçao..............
