Key to females of Sternostoma species known from Canada:
1. |
One dorsal shield, sternal setae large, proximally
inflated blunt tipped spines |
Sternostoma technaui |
- |
Two dorsal shields, sternal setae minute spines |
2 |
2. |
Apical setal pair on palp tarsus proximally inflated,
medially constricted and distally flattened, in form of a T with an
inflated base. Tarsi II – IV subapical ventral and ventrolateral setae
relatively long spines |
Sternostoma longisetosae |
- |
Apical setal pair on palp tarsus long spines, short spines, or short bulbs, not T-like. Tarsi II –
IV subapical
ventral and ventrolateral setae either relatively long spines or otherwise |
3 |
3. |
Tarsus IV anterodorsal apical seta long prominently swollen spike with flexible
tip. Tarsi II - IV subapical ventral setal
pair short blunt tipped stout spines,
especially noticeable on tarsus IV |
Sternostoma
porteri |
- |
Tarsus IV anterodorsal apical seta not swollen, long hair-like. Tarsi II – IV subapical
ventral setal pair either short blunt
tipped stout spines or otherwise |
4 |
4. |
Tarsi II – IV subapical ventral setal pair short blunt
tipped stout spines, especially
noticeable on tarsus IV. Postanal
seta present |

- |
Tarsi II – IV subapical ventral setal pair otherwise.
Postanal seta absent |
5 |
5. |
Tarsi II – IV subapical ventral setal pair short flattened setae with rounded tips. No setae
in dorsal opisthosomal unsclerotized integument |
Sternostoma boydi |
- |
Tarsi II – IV subapical ventral setal pair otherwise.
One or more pairs of setae in dorsal opisthosomal unsclerotized
integument |
6 |
6. |
Tarsi II – IV subapical ventral and ventrolateral
setae relatively long spines. More than three pairs
of setae in dorsal
opisthosomal unsclerotized integument |
Sternostoma setifer |
- |
Tarsi II – IV subapical ventral and ventrolateral
setae otherwise. Fewer than three pairs of setae in dorsal
opisthosomal unsclerotized integument |
7 |
7. |
Tarsi II – IV subapical ventral and ventrolateral
setae minute spines, barely visible. Two pairs of
setae in dorsal
opisthosomal unsclerotized integument |
Sternostoma tracheacolum |
- |
Tarsi II – IV subapical ventral and ventrolateral
setae variously modified, not minute spines. One or two pairs of setae in
dorsal opisthosomal unsclerotized integument |
8 |

Tarsi II – IV subapical ventral and ventrolateral
setae hook-like short spines. Two pairs of setae in
dorsal opisthosomal unsclerotized integument |
Sternostoma laniorum |
- |
Tarsi II – IV subapical ventral and ventrolateral
setae distally inflated setae. One or two pairs of
setae in dorsal
opisthosomal unsclerotized integument |
9 |
9. |
Tarsi II – IV subapical ventral and ventrolateral
setae distally inflated symmetrical setae. Two
pairs of setae in dorsal
opisthosomal unsclerotized integument. Paranal setae at level with anal opening |
Sternostoma cryptorhynchum |
- |
Tarsi II – IV subapical ventral and ventrolateral
setae distally inflated asymmetrical setae. One
pair of setae in
dorsal opisthosomal unsclerotized integument. Paranal setae posterior to anal opening |
10 |
10. |
One pair of setae and one pair of
pores in dorsal opisthosomal unsclerotized integument |
Sternostoma loxiae |
