  1. Very well done! Thanks for humoring me :).

    This image gives a really nice look at the spiracular plates!

    I also *think* I can see the tiny coxal organs located between the bases of the coxae of the 1st and 2nd pair of legs. The coxal organs filter out excess fluid and salts from bloodmeals, which then pass through the opening. It's hard to differentiate male/female argasid ticks. But, judging from the shape and size of the genital opening, this tick is probably female. But, considering male and female soft ticks ingest blood, unlike ixodid ticks, both sexes are potential disease vectors. So, IDing male vs female soft ticks isn't considered to be that important even though it's still interesting, to me at least. ;P

    1. Thanks for the additional information. Posted 2 months ago, modified 2 months ago
      1. Actually -- Soft (Argasidae) ticks do not have a scutum or conscutum. In hard (Ixodidae) ticks, the female has a dorsal scutum, while the male has a dorsal conscutum. The male conscutum is large and covers almost the entire dorsal surface of the body. In females, the scutum is smaller and is restricted to the anterior dorsal surface, just behind the capitulum. Hard ticks are called "hard" because the scutum/conscutum is a hard, sclerotized plate that is lacking in soft ticks.

        I'll share a link in a sec if I can find one...

        1. For Ixodid (hard ticks):
          http://www.bristoluniversitytickid.uk/uploads/file/image/yw0tmrz9es0y_img_ScutumConscutum.jpg

          See section titled 'Scutum or Conscutum' under 'A General Account of Ticks' on the right side:
          https://www.sciencedirect.com/topics/veterinary-science-and-veterinary-medicine/gnathosoma

          Simply referred to here as the 'scutum' here because 'conscutum' is not a term usually used:

          This link shows a diagram of the lack of scutum or conscutum in males. I totally defer to your experience.

          1. ^THAT is the perfect diagram for this topic! Glad you found it!

            And, now you may know more than you ever wished to know about soft ticks, lol.

        3. This is the link I saw the information about conscutum.

          These ticks are just crazy. How much fun can one frustrated want to be entomologist like me have?

''Argas persicus'', also known as fowl tick or poultry tick, is a small soft-bodied tick that is found primarily on domestic fowl such as chickens, ducks, and geese. It was first recorded by Lorenz Oken in 1818 in Mianeh, Persia, and named ''Rhynochoprion persicum''.

''Argas persicus'' appears yellowish-brown when starved and slatey-blue when engorged. They are found on an animal host, in cracks and crevices of buildings or in nests.

They are also carriers of the spirochete.. more
