fig 10 unionicola general
Here is a new unionicola . The pictures are rather good but I havent reach the identification to specie.
Some observations
- Length of the body 0.9mm.
- End of the legs blueish
- Proximal part of the legs pink pearl.
- Malpigian vessel orange.
- First 2 pairs of legs with strong setae.
- Legs III and IV with small setae.
- Coxae plates covering more than 4/5 of the ventral area.
- Genital plates sickle shape.
- Genital area at the very rear of the body.
- A lot of acetabulae on the genital plates.
- 2 dark sclerites on each side of the genital area
- Genital plates blueish.
- Strange pattern for the dark part of the body (midgut lobes) with dark spot in a kind of greenish jelly.
The possibility of Unionicola ypsilophora.
I’ve spend some hours thinking it was an Unionicola ypsilophora and I’m rather concinced now that is is not. I’ve keep a track of this identification in a separate blog entry on « why this is not an Unionicola ypsilophora »

Where is your mite from? How was it collected? First and foremost, a good illustration of the male and/or female genital field(s) is/are essential.
Looks like a number of species–many free-swimming. If the mite is from Europe, then Unionicola (Pentatax) bonzi is initial guess based upon what is illustrated. There are a number of similar species that must however be ruled out for any concise conclusion.
I would like to view the specimen.

Dear Colleague, I am pleased to send you photos of some species of Hydrachnidia harvested in the Northeast region of Algeria and I have not been able to identify (lack of identification keys for North African) species. The Mediterranean region is hot and humid climate in the north of Africa.
I hope you find any collaboration. Accept my most distinguished thanks
