Key to Euophrys species

Females

1 More than 50 % of the spermatheca posterior to the fossa and guide (e.g. Fig. 59) .................................................... 2

- Less than 50 % of the spermatheca posterior to the fossa and guide (e.g. Fig. 64)...................................................... 6

2 Spermatheca smaller than the fossa and inner edge of the fossa well beyond the outer edge of the spermatheca; L 4 patterning as in Fig. 3 D ............................................................................................................ E. anotata ( Figs 49–55)

- Spermatheca equal to or larger than the fossa and inner edge of the fossa near or overlapping the outer edge of the spermatheca ................................................................................................................................................................. 3

3 Insemination duct anterior to the fossa and guide, fossa O-shaped, and wide apart so just overlapping spermatheca; L 4 patterning as in Fig. 3 F ................................................................................................. E. patagonica ( Figs 73–79)

- Insemination duct not passing anterior to the fossa and guide, fossa C-shaped, inner edges of guide overlap the sper- matheca ........................................................................................................................................................................ 4

4 Fossa placed dorsolaterally to, and overlap, the spermatheca, guides open anteriorly; L 4 patterning as in Fig. 3 B .... .............................................................................................................................................. E. rusticana ( Figs 89–95)

- Fossa dorsal to the spermatheca and guides open ventrolaterally .............................................................................. 5

5 Dark pattern on the abdomen forms two longitudinal bands; femur of L 4 a plain yellow colour (may occasionally have faint markings ( Fig. 3 E) .......................................................................................... E. saitiformis ( Figs 96–102)

s- Dark pattern on the abdomen scattered, does not form two longitudinal bands; three dark bands on a yellow back- ground on the femur of L 4 ( Fig. 3 H) ...................................................................... E. flordellago n. sp. ( Figs 56–62)

6 Inner edge of the fossa beyond the outer edge of the spermatheca ............................................................................ 7

- Inner edge of the fossa overlaps the spermatheca ....................................................................................................... 8

7 Entrance to the insemination duct close to the anterior edge of the fossa; L 4 patterning as in Fig. 3 E ........................ .................................................................................................................................................. E. laetata ( Figs 63–65)

- Entrance to the insemination duct close to the posterior edge of the fossa; L 4 patterning as in Fig. 3 G ...................... .......................................................................................................................................... E. tehuelche ( Figs 103–109)

8 Median edges of the fossae touching, guide opens posterolaterally; L 4 patterning as in Fig. 3 C ................................. ................................................................................................................................................ E. mapuche ( Figs 66–72)

- Median edges of the fossae not touching, guide opens dorsolaterally; L 4 patterning as in Fig. 3 A .............................

.................................................................................................................................................. E. rapida ( Figs 80–88)

Males

As the males are not known for E. laetata , E. saitiformis and E. flordellago no key is given. Compare specimens with Figs 2 and 3.
