Type species. Meyeraepalpus strandtmanni Smiley, Frost and Gerson, 1996  , by original designation.

Diagnosis. All life stages: dorsal opisthosoma with 12 or 13 pairs of lanceolate setae; c 2, d 2, and e 2 present; seta f 2 present or absent; setae e 2 inserted in more-or-less marginal position; setae h 2 similar in size and form to other dorsal setae; palps 5 -segmented, setal formula 0,0,0,2,3(1); immature stages with anterior margin of prodorsum smoothly rounded, without projections/notches, gnathosoma not concealed; ventral plate absent; 3 pairs of pseudanal setae (ps 1–3) on weakly developed anal plates. Adult female: anterior margin of prodorsum deeply incised, forming 1 pair of broad fleshy lobes, each lobe bearing setae v 2 (also in male); gnathosoma partially concealed by anterior margin of prodorsum (also in male); genital plate weakly developed, membranous; metapodal plates not developed; coxae I without setae 1 c; trochanters I –IV 0- 0-1 -0 (v ′ absent on tr I –IV; l ′ present on tr III); femora I –IV 3 - 3 - 2 - 1; genua 1 - 1 -0-0 (d present on ge I –II); tibiae 4 - 4 - 3 - 3; tarsi I –IV 8 (1)- 8 (1)- 4 - 4 (without tc′′). Solenidia of male much thicker and longer than in female.

Species. Three species: M. strandtmanni  , M. caperatus  , M. forsteri  .

Hosts and distribution. Casuarinaceae  , Australia.

Remarks. The new species described herein differ from the type species by lacking seta f 2. Although this is an important difference, these species share the same leg setation, a deeply incised prodorsum with setae v 2 inserted on the resultant lobes, and a partially concealed gnathosoma.
