Piona conglobata ? General view
Here are some pictures inviting to identify this hydracarina as Piona Conglobata but I can’t swear that it’s correct.
Description.
- Coxae 3 and 4 not jointed.
- Straight and parallel line between the inner border of coxae 3 and 4.
- Spine under the segment 3 of the palpi.
- Size about 1.mm length.
- Eyes black.
- First segment of the palpi about one and a half as the proximal segment of the first pair of leg. (It lokks like this description from S&W).
- A lot of bristles and swimming hair on the legs.
- Genital sclerite visible almost between the margin of the fourth epimera.
Elements of Soar & Williamson problematic or unchecked.
- Colour yellowish, brownish or bluish-green.
- Palpi, epimera and legs usually bluish, the terminal segment of the legs frequently of a brownish tint. Mine is neither blueish neither with the end of legs brownish.
- The genital area described by Soar and Williamson are very difficult to check on my pictures.
Tracks followed for the identification.
- Piona conglobata. Key Hopkins for the Flatword Area – Fig 72. But size 0.6mm. General shape of coxae plates III and IV rather matching my pictures.
- Piona Conglobata. Soar & Williamson page 182. Size up to 1.1mm : OK (female 1.1 – male 0.6).
