Key to Brazilian species of Leschenaultia  

This key is adapted from Toma & Guimarães (2002).

1 Head with grayish-yellow pruinosity...................................................................... 2

- Head with gray pruinosity............................................................................... 3

2 First flagellomere about 2.5x length of pedicel; cercus in profile well tapered and elongated ( Fig. 9 View FIGURES 9–14 )......... andarae   sp. n.

- First flagellomere less than twice length of pedicel; cercus in profile less tapered and shorter (see Toma & Guimarães 2002: fig. 48).......................................................................... bigoti Toma & Guimarães  

3 Abdominal syntergite 1+2 and tergite 3 without median marginal setae; tergite 3 without discal setae (see Toma & Guimarães 2002: fig. 94)........................................................................... bicolor (Macquart)  

- Abdominal syntergite 1+2 and tergite 3 with median marginal setae; tergite 3 with or without discal setae................ 4

4 Abdominal tergite 4 without discal setae; if present, then very few scattered setae (see Toma & Guimarães 2002: figs 104, 108– 110)................................................................................................ 5

- Abdominal tergite 4 with a group or a row of discal setae (see Toma & Guimarães 2002: figs 103, 106, 112)............ 12

5 Abdominal tergite 3 with a small group of short discal setae near median marginal setae (see Toma & Guimarães 2002: fig. 104).......................................................................... aldrichi Toma & Guimarães  

- Abdominal tergite 3 without discal setae; if present, then almost undifferentiated from the ground setulae (see Toma & Guimarães 2002: fig. 108–110)........................................................................... 6

6 Abdominal syntergite 1+2 with a few pairs of short but conspicuous median marginal setae; tergite 3 with at least five pairs of short, thick, uniform and aligned median marginal setae (see Toma & Guimarães 2002: fig. 110).................................................................................................... coquilletti Toma & Guimarães  

- Abdominal syntergite 1+2 with a few pairs of very short median marginal setae almost undifferentiated from ground setulae; tergite 3 with fewer pairs of short, median marginal setae almost undifferentiated from ground setulae; if tergite 3 median marginal setae differentiated and thicker than the ground setulae, then they are not as above (see Toma & Guimarães 2002, figs 108 and 109)............................................................................................. 7

7 Abdominal tergite 3 with short and thick median marginal setae (see Toma & Guimarães 2002: fig. 108); cercus in profile tapering strongly in apical third (see Toma & Guimarães 2002: fig. 50)................ bergenstammi Toma & Guimarães  

- Abdominal tergite 3 with short median marginal setae almost undifferentiated from ground setulae (see Toma & Guimarães 2002: fig. 109); cercus not as above....................................................................... 8

8 Fore claws shorter than second fore tarsomere.......................................... braueri Toma & Guimarães  

- Fore claws longer than second fore tarsomere............................................................... 9

9 Cercus in profile posteriorly with a kink and backward bent in apical third ( Fig. 12 View FIGURES 9–14 )......................... liriai   sp. n.

- Cercus in profile posteriorly with a kink and backward bent situated close to apex................................. 10

10 Cercus in profile almost entirely straight, posteriorly slightly bent backward near apical fifth and anteriorly gently curved in apical third (see Toma & Guimarães 2002: fig. 52)............................... brooksi Toma & Guimarães   (in part)

- Cercus in profile not as above ( Figs 10–11 View FIGURES 9–14 )................................................................ 11

11 Mid tibia with about eight stout anterodorsal setae, the longest about 1.9x length of anteroventral seta........ belkysae   sp. n.

- Mid tibia with three or four strong anterodorsal setae, the longest about 2.4x length of anteroventral seta..... frangeri   sp. n.

12 Discal setae on abdominal tergite 4 almost aligned (see Toma & Guimarães 2002: fig. 106)........ bessi Toma & Guimarães  

- Discal setae on abdominal tergite 4 arranged in a group (see Toma & Guimarães 2002: figs 103, 112).................. 13

13 Abdominal tergite 3 usually with less than four pairs of very short and thin median marginal setae and with a group of short and thin discal setae; cercus in profile almost entirely straight, posteriorly slightly bent backward near apical fifth, anteriorly gently curved in apical third, and very slightly tapered in apical third (see Toma & Guimarães 2002: fig. 52)...................................................................................... brooksi Toma & Guimarães   (in part)

- Abdominal tergite 3 usually with four or more pairs of short median marginal setae and a group of short but conspicuous discal setae (see Toma & Guimarães 2002: figs 103, 112); cercus in profile posteriorly bent backward near apical third (see Toma & Guimarães 2002: figs 44, 55); if cercus posteriorly bend backward near apical fifth, then anteriorly more curved in apical third, and apical third more tapered ( Fig. 13 View FIGURES 9–14 ).................................................................... 14

14 Cercus in profile posteriorly bent backward near apical fifth ( Fig. 13 View FIGURES 9–14 )............................... marjorieae   sp. n.

- Cercus in profile posteriorly bent backward near apical third (see Toma & Guimarães 2002: figs 44, 55)................ 15

15 Abdominal tergites 3 and 4 with moderately thick discal setae (see Toma & Guimarães 2002: fig. 103); cercus in profile narrow and sinuous in apical third (see Toma & Guimarães 2002: fig. 44)....................... cilipes Robineau-Desvoidy  

- Abdominal tergites 3 and 4 with thicker discal setae (see Toma & Guimarães 2002: fig. 112); cercus in profile broader and less sinuous in apical third (see Toma & Guimarães 2002: fig. 55).............................. currani Toma & Guimarães
