Key to the species of Xenopygus

1. Antenna with microsetae on antennomeres IV to XI; antennomere IV longer than wide, pronotum with setal punctuations evenly distributed, not on the median longitudinal line (Fig. 11–13); sternite VII of male without porous structure......... 2

- Antenna with microsetae on antennomeres V to XI ( Fig. 14 View FIGURES 14 – 19 ); antennomere IV as long as wide ( Fig. 14 View FIGURES 14 – 19 ), pronotum with setal punctuations forming a pair of longitudinal parallel lines in the median region and distributed in the lateral thirds (Fig. 5–7); sternite VII of male with porous structure (Figs. 30–32)...................................................... 4

2. Tergite V with arched carina.................................................................. X. cordovensis

- Tergite V without arched carina.......................................................................... 3

3. Median lobe with only one large tooth in the apex ( Fig. 49 View FIGURES 48 – 50 ); paramere with rounded apex and peg setae along its margin (Fig. 55)............................................................................. X. sancticamillus , sp. nov.

- Median lobe with more than two somewhat small teeth near the apex ( Fig. 50 View FIGURES 48 – 50 ); paramere with thin apex and peg setae forming two parallel columns (Fig. 56).......................................................... X. petilicolis , sp. nov.

4. Head and pronotum of the same color as elytra, metallic blue to green, sometimes with elytra slightly darker, and abdominal

segment VII entirely yellowish or at least ligther than the precedents ( Fig. 2 View FIGURES 2 – 4 ); scape evidently shorter than antennomeres II and III combined................................................................................... X. analis - Head and pronotum of different color that elytra and abdominal segment VII not entirely ligther than the preceeding segments ( Figs. 3, 4 View FIGURES 2 – 4 ); scape slightly longer than antennomeres II and III combined.......................................... 5
