Inner lobe (praecoxal arthrite) with 3 elements: outermost element spiniform, swollen at base, ornamented with row of spinules along 1 side and several spinules on the other side, tip with tubular extension; middle element setiform and bare; innermost element smallest located along concave inner margin close to other elements, swollen at base and ornamented with 1 (or 2?) spinules. Outer lobe with 3 setiform elements [innermost element absent], which are curved and bare, innermost seta longest.
