Tegopalpus Womersley, 1940


Tegopalpus Womersley, 1940 

Type species. Tegopalpus conicus Womersley, 1940  , by monotypy.

Diagnosis. All life stages: dorsal opisthosoma with 9 pairs of short broadly lanceolate setae; c 2, d 2, e 2 and f 2 absent; setae h 2 similar in size and form to other dorsal setae; palps 3 -segmented, palp setal formula 0, 0, 2 (1); immature stages with anterior of prodorsum smoothly rounded, without projections/notches; ventral plate absent; 3 pairs of pseudanal setae (ps 1–3) on weakly developed membranous anal plates. Adult female: gnathosoma completely concealed by prodorsum; cuticle between gnathosoma and prodorsum produced into 1 pair of blunt, broadly triangular membranous lobes (with median notch formed between the lobes), anterior to and folded under anterior margin of prodorsum and setae v 2, often appear slightly retracted back into body; genital plate weakly developed, membranous; metapodal plates not developed; coxae I without 1 c; trochanters I –IV 0- 0-1 -0 (v ′ absent on tr I –IV); femora I –IV 3 - 3 - 2 - 1; genua I –IV nude; tibiae I –IV 3 - 3 - 2 - 2 (v′′ absent on ti I –IV); tarsi I –IV without tc′′. Solenidia of male of similar thickness and length as in female.

Remarks. This monotypic genus is close to Chaudhripalpus  , differing only in having a three-segmented palp (instead of four) and tibiae I –IV lacking setae v′′. Here, we tentatively retain Chaudhripalpus  as a separate genus, as the three-segmented palp of Tegopalpus  is autapomorphic within the Tegopalpinae and mites found on Casuarinaceae  .
