Diagnosis.
Saepocephalum stephenfryi
n. sp.
is separated from all other known
Brueelia
-complex species by the combination of the following unique characters: tergopleurites do not reach lateral margins of abdomen and pleural incrassations run only along anterior margin of tergopleurites (
Figs 238–239
); cross-piece laterally detached from female subgenital plate (
Fig. 245
); parameral heads with ridges anteriorly (
Fig. 244
). In addition, the following characters set
Sa
.
stephenfryi
apart from most other species of the complex: clypeo-labral suture does not reach the frons and ventral anterior plate is continuous with marginal carina (
Fig. 240
) as in
Harpactrox
n. gen.
(
Fig. 248
) and
Anarchonirmus
n. gen.
(
Fig. 116
); mesosomal lobes fused distally (
Fig. 243
);
pst1–2
both sensilla; dorsal preantennal suture absent or present only around
ads
(
Fig. 240
) as in some
Priceiella
n. gen.
(
Fig. 279
); antennae sexually dimorphic (
Figs 240–241
). The differences between
Saepocephalum
and these genera are outlined in the genus description above.
Description.
Both sexes
. Head shape, structure, and chaetotaxy as in genus description and
Fig. 240
;
pts
and
pns
very short, not visible in all specimens examined. Dorsal anterior suture surrounding
ads
not present in all specimens examined. Thoracic and abdominal segments as in genus description and
Figs 238–239
. Antero-lateral thickenings of tergopleurites variable between specimens, typically arched.
Male
. Antennae as in
Fig. 240
, scape swollen and elongated. Abdominal chaetotaxy as in
Table 2
and
Fig. 238
. Basal apodeme (
Fig. 242
) with diffuse anterior end, much widened. Proximal mesosome slender, elongated, overlapping with basal apodeme; anterior margin thickened. Gonopore ventral (
Fig. 243
), widely open distally, with bifurcate distal ends (
Fig. 180
). Mesosomal lobes fused distally, slender; 2
pmes
on lateral margins of each lobe. Parameral heads (
Fig. 244
) roughly rectangular, with serrated posterior margin and prominent ridges. Parameral blades much elongated, slender, with distinct heel just distal to mesosome;
pst1–2
both sensilla. Measurements ex
Corcorax melanorhamphos
(n = 1, due to mounting of specimen HL and TL cannot be measured): HW = 0.40; PRW = 0.20; PTW = 0.40; AW = 0.64.
Female
. Antennae as in
Fig. 241
. Abdominal chaetotaxy as in
Table 2
and
Fig. 239
. Subgenital plate (
Fig. 245
) funnel-shaped, reaching vulval margin. Vulval margin (
Fig. 245
) with lateral marginal plates unconnected to subgenital plate (except on one side in one specimen). Vulval margin (
Fig. 245
) gently rounded, bulging somewhat medianly, with 3–4 short, slender
vms
on each side, and 4–7 (in one specimen 3) thorn-like
vss
on each side, lateral
vss
progressively more spool-like; 4–7 long, slender
vos
; distal 1–3
vos
median to
vss
. Measurements ex
Corcorax melanorhamphos
(n = 5): TL = 1.80–2.04; HL = 0.39–0.42; HW = 0.43–0.46; PRW = 0.21–0.23; PTW = 0.39– 0.45; AW = 0.61–0.70.
Etymology.
The species epithet is in honour of the actor, comedian, writer, and unique intellectual Stephen Fry (b. 1957), whose productions have delighted, entertained, provoked, and educated DG during the writing of this revision. Just as this is a revision of one, often misunderstood, complex of lice, Stephen Fry's quiz show “
QI
” can be seen as a revision of the complexity of human knowledge, one misunderstanding at the time.
