Kontschán, Jen Ő, 2010, Bloszykiella africana gen. nov., sp. nov., a new mite genus from East Africa (Acari: Mesostigmata: Uropodidae), Zootaxa 2525, pp. 63-68 : 63-64

Bloszykiella gen. nov.

Diagnosis. Idiosoma oval, dorsally domed, marginal and dorsal shields fused anteriorly. All dorsal setae short, with pilose distal margins. Submarginal shield reduced posteriorly, pygidial shield in females trapezoidal, bearing one pair of pilose setae. Five pairs of sternal setae smooth and needle-like in females, pilose in deutonymphs. Genital shield of female trapezoidal, with anterior margin situated between coxae III. Peritreme L-shaped in female. Tritosternum with vase-like base, its laciniae subdivided into irregular pilose branches in female and deutonymph. Hypostomal setae h 1 in female and nymph pilose in central one-third, distally and basally smooth, h2 placed close to h1, short, smooth in females and pilose in nymphs, h3 smooth in both stages, h4 pilose in nymphs and smooth in females. Palp trochanter with long serrate setae in both stages. Corniculi small and horn-like, fixed digit of chelicerae as long as movable digit, bearing several large short teeth. Chelicerae without internal sclerotised nodes. Leg I without abulacral claws; with serrate setae on trochanter and smooth setae on other segments.

Etymology. I dedicate the new genus to Uropodina researcher Prof. Jerzy Błoszyk (Adam Mickiewicz University, Poznań, Poland).

Gender. Feminine.

Type species. Bloszykiella africana sp. nov.

Notes on the genus. The shape of the chelicera, with numerous large short teeth, is similar to the chelicerae of the genera Baloghjkaszabia Hirschmann 1973 , Kaszabjbaloghia Hirschmann 1973 , and Wernerhirschmannia Hiramatsu 1983 , but the new genus differs from these genera in several characters ( Table 1). Similar chelicerae can also be found in the genus Multidenturopoda Wiśniewski & Hirschmann 1991 , which is only known from the deutonymph and protonymphs. The distinguishing characters between deutonymph of the new genus and the deutonymphs of Multidenturopoda are summarised in Table 2. The remainder of the genera of Uropodina do not have this type of chelicera. The new genus is also distinctive in the shape and length of hypostomal setae and the shape of the tritosternum.

Unfortunately the families of Uropodina are not well defined, and the Uropodina classification system is quite confusing. I provisionally place the new genus in the family Uropodidae on the basis of the following characters: long h1 setae; chelicerae without internal sclerotised node and without mushroom- or flowershaped sensory organ on fixed digit; terminally smooth corniculi ( Lindquist et al. 2009), but all members of this family need revision.
