Meyeraepalpus strandtmanni Smiley, Frost and Gerson, 1996 , by original designation. Diagnosis. All life stages: dorsal opisthosoma with 12 or 13 pairs of lanceolate setae; c2 , d2 , and e2 present; seta f2 present or absent; setae e2 inserted in more-or-less marginal position; setae h2 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 ( ps1–3 ) on weakly developed anal plates. Adult female: anterior margin of prodorsum deeply incised, forming 1 pair of broad fleshy lobes, each lobe bearing setae v2 (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 1c ; 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 f2 . Although this is an important difference, these species share the same leg setation, a deeply incised prodorsum with setae v2 inserted on the resultant lobes, and a partially concealed gnathosoma.
