Magdalenapalpus
Mesa, Welbourn and Evans, 2009
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;
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.
