Diagnosis.
Resartor
n. gen.
is most similar to
Ceratocista
n. gen.
; for a detailed comparison between these two genera see
Ceratocista
. Lack of
pos
and
pns
, as well as general habitus similar to
Aratricerca
n. gen.
(
Figs 168– 174
) and
Turdinirmoides
n. gen.
(
Figs 175–181
), and members of these two genera also have thumb-like median extensions on the ventral carinae and slender proximal mesosomes. Leg chaetotaxy of
Ceratocista
,
Resartor
, and
Aratricerca
, but not
Turdinirmoides
, is identical, and
aps
are absent in both sexes in all four genera. However, while in
Ceratocista
(
Fig. 154
) and
Resartor
(
Fig. 162
) the females lack
ss
entirely, these are found in tergopleurites II–VIII in both
Aratricerca
(
Fig. 169
) and
Turdinirmoides
(
Fig. 176
). In both
Aratricerca
(
Fig. 170
) and
Turdinirmoides
(
Fig. 177
) the dorsal preantennal suture reaches
dsms
,
ads
, and the lateral margin of the head near the
dsms
, where the marginal carina may be interrupted, and both genera have a ventral anterior plate. In
Resartor
(
Fig. 163
), as in
Ceratocista
(
Fig. 155
), the dorsal preantennal suture only interrupts the marginal carina submedianly, and does not reach either the
dsms
nor the
ads
;
Resartor
lacks a ventral anterior plate, but this is present in
Ceratocista
. The female subgenital plate of
Resartor
flares into a mediany interrupted cross-piece (
Fig. 167
), just like in
Ceratocista
(
Fig. 160
), but unlike
Aratricerca
which has a gently narrowed subgenital plate without a cross-piece (
Fig. 174
); the vulval margin in
Turdinirmoides
(
Fig. 181
) has a detached cross-piece. Parameral heads of
Resartor
are bifid (
Fig. 166
), as in
Aratricerca
(
Fig. 173
) and
Ceratocista
(
Fig. 159
), but unlike
Turdinirmoides
(
Fig. 180
) in which they are folded into horseshoe-shapes. Parameral blades and mesosome of
Resartor
(
Figs 165–166
) are also most similar to those of
Ceratocista
(
Figs 158–159
), but
Resartor
shares the somewhat angular mesosomal lobes and slender proximal mesosome with
Aratricerca
n. gen (
Fig. 172
); the differences is structure of the male genitalia are considerable between the two genera, however.
Description.
Both sexes
. Head elongated pentagonal (
Fig. 163
), frons often concave. Marginal carina interrupted only submarginally. Displaced section of marginal carina present at osculum, forming nail-like marginal carinal plate with sinuous posterior margin. Dorsal preantennal suture arising from interruptions of marginal carina not reaching
ads
or
dsms
; suture not medianly continuous posterior to dorsal anterior plate. Ventral carinae with finger-like median protrusion; carinae diffuse anterior to pulvinus. Ventral anterior plate absent. Head setae as in
Fig. 163
;
avs2
much shorter than
avs3
;
pns
and
pos
absent. Coni small. Antennae monomorphic. Temporal carinae not visible;
mts
3
only macrosetae. Gular plate roughly triangular.
Prothorax roughly rectangular (
Figs 161–162
), but lateral margins convex;
ppss
on postero-latera corner. Proepimera hammer-shaped medianly. Pterothorax pentagonal; lateral margins divergent and posterior margin convergent to median point (
Figs 161–162
). Meso- and metasterna not fused, 1 seta on postero-lateral corner on each side of each plate.
mms
widely separated medianly. Leg chaetotaxy as in
Fig. 25
, except
fI-p2, fI-v4
absent.
Abdomen (
Figs 161–162
) oblong. Abdominal chaetotaxy differs among species (
Table 5
). Terminal end of abdomen rounded in male, shallowly divided in female. Tergopleurites II–IX+X in male and tergopleurites II–VIII in females narrowly divided medianly, rectangular. Female tergopleurite IX+X fused with tergopleurite XI. Sternal plates square-shaped, not approaching pleurites. Pleural incrassations prominent. Re-entrant heads moderate to large.
Male
subgenital plate trapezoidal. Female subgenital plate pentagonal (
Fig. 167
), reaching vulval margin where it flares into medianly displaced cross-piece.
TABLE 5.
Chaetotaxy of abdominal segments II–VIII of males of
Resartor
. Trichoid setae of segment VIII are present in all species, and are not listed. Sets of setae differing from those of
Re. impressifrons
are highlighted in
bold
. Material examined from all species is from their respective type hosts. Abbreviations:

Male
genitalia as in
Fig. 164
. Proximal mesosome slender, roughly trapezoidal, wideing slightly in proximal end. Gonopore (
Fig. 165
) as convergent ventral thickenings, open distally and proximally or only distally and extended to reach lateral margins of mesosome. Mesosomal lobes small, angular, extending dorsally to slightly overlap with parameres. Parameral heads (
Fig. 166
) bifid or folded into small heart-shapes. Parameral blades triangular;
pst1–2
not visible, but all examined males with partially everted male genitalia, and these could be overlooked.
Host
distribution.
All known species are found on members of
Leiothrichidae
.
Geographical range.
Presently know only from
South
Asia.
Etymology.
Resartor
is formed by Latin “
sartor
”, meaning “tailor”, with the prefix “
re-
” meaning “back, again”; the full name thus means “The Re-tailor”, and is modified from the title of Thomas Carlyle's (
1795–1881
) “
Sartor Resartus
”, first published in Fraser's Magazine between
1833–1834
. The name is partially a homage to the idea, first suggested by
Hamilton & Zuk (1982)
, that parasites could be the cause of colorful and extravagant plumages in birds; lice could thus be said to be “re-tailoring” the plumages of their hosts. However, there is also a likeness between the head structure the species of this genus and the structure of the needle plate of many modern sewing machines, reinforcing the “tailoring” impression of these lice. Gender: masculine.
Remarks.
The phylogeny of Bush
et al
. (2016) included a single undescribed species of
Resartor
from
Trochalopteron milnei
(David, 1874)
, which was placed as sister to an undescribed
Aratricerca
from
Randia pseudozosterops
Delacour and Berlioz, 1931
. These two in turn were placed close to
Indoceoplanetes
n. gen.
and
Maculinirmus
, but the placement received low support. However, no representative of several morphologically similar genera were included in that phylogeny, and the relationships among
Resartor
and
Turdinirmus
and
Turdinirmoides
n. gen.
are unclear.
