Cohort Uropodina

    Subcohort Uropodiae

Superfamily Uropodoidea Kramer - Family Uropodidae Kramer (s.l.)

 

Dinychidae Berlese

Dinychus Kramer, Prodinychus Berlese

Diagnostic characters:

• Uropodoids with flattened, adjacent coxae I but without pedofossae

• Tarsus I with claws

• Cheliceral node present

• Genital shield as wide as long

• Hypostomal setae h1-3 smooth, acicular; pc short and barbed

• Peritreme usually with post-stigmatic extension

• Dorsal shield typically strongly reticulate or punctate

• Fixed digit of chelicerae with well developed anterior extension.

Similar taxa.  Lower uropodines typically have well separated coxae I and large, rectangular tritosternal bases; most higher uropodines have well developed pedofossae (fovae pedales).
