Description.
Both sexes
. Head shape, structure, and chaetotaxy as in genus description and
Fig. 499
;
pos
clearly ventral, sublateral, just posterior to eye;
mts
2
about twice as long as
mts
1
. Preantennal nodi short, elongated, pointed. Postantennal suture wide but anterior margin generally diffuse. Thoracic and abdominal segments as in genus description and
Figs 497–498
.
Male
. Abdominal chaetotaxy as in
Table 2
and
Fig. 497
.
Male
genitalia distinct (
Fig. 500
). Basal apodeme trapezoidal. Mesosome irregularly oval, wider than long; broad median extension posteriorly, with distal margin of extension deeply concave. Anterior section of mesosome with a densely papillate transversal ridge, connected medianly to a papillate area with a gently rounded posterior margin; 2
ames
microsetae on each side lateral to papillate ridge; 3
pmes
sensilla on each side as in
Fig. 500
. Parameres stout, angled. Distal translucent section of parameres very large; 3
pst
sensilla near distal end of parameres. Measurements ex
Merops ornatus
(n = 6): TL = 1.59–1.88; HL = 0.52–0.59; HW = 0.68–0.75; PRW = 0.33–0.40; PTW = 0.51–0.62; AW = 0.71–0.82.
Female
. Abdominal chaetotaxy as in
Table 2
and
Fig. 498
. Median extension of subgenital plate short, blunt (
Fig. 501
). Vulval margin slightly convergent medianly, with median section distinctly bulging (
Fig. 501
). Bulge with 3–4 short, stout
vms
and 4–5 short, thorn-like
vss
on each side. Lateral to bulge 9–10 long, slender
vms
on each side and 5–6 short, thorn-like
vss
on each side; 6–7 short, slender
vos
forming broadly convergent rows, with distal
vos
approaching
vss
. Measurements ex
Merops ornatus
(n = 3): TL = 1.75–2.27; HL = 0.58–0.62; HW = 0.76–0.84; PRW = 0.37–0.40; PTW = 0.57–0.63; AW = 0.79–1.00.
Etymology.
The species epithet is in honour of Andrew Bartlow, University of
Utah
, Salt Lake City,
Utah
, in recognition of his work on the distribution and dispersal of bird and mammal parasites.
