Saepocephalum stephenfryi Gustafsson & Bush  , new species

( Figs 238–245View FIGURES 238 – 239View FIGURES 240 – 245)

Type host. Corcorax melanoramphos (Vieillot, 1817)  —white-winged chough. Type locality. 10 km S of Wyalong, New South Wales, Australia.

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 238–239View FIGURES 238 – 239); cross-piece laterally detached from female subgenital plate ( Fig. 245View FIGURES 240 – 245); parameral heads with ridges anteriorly ( Fig. 244View FIGURES 240 – 245). 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. 240View FIGURES 240 – 245) as in Harpactrox  n. gen. ( Fig. 248View FIGURES 248 – 252) and Anarchonirmus  n. gen. ( Fig. 116View FIGURES 116 – 121); mesosomal lobes fused distally ( Fig. 243View FIGURES 240 – 245); pst1–2 both sensilla; dorsal preantennal suture absent or present only around ads ( Fig. 240View FIGURES 240 – 245) as in some Priceiella  n. gen. ( Fig. 279View FIGURES 279 – 284); antennae sexually dimorphic ( Figs 240–241View FIGURES 240 – 245). 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. 240View FIGURES 240 – 245; 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 238–239View FIGURES 238 – 239. Antero-lateral thickenings of tergopleurites variable between specimens, typically arched.

Male. Antennae as in Fig. 240View FIGURES 240 – 245, scape swollen and elongated. Abdominal chaetotaxy as in Table 2 and Fig. 238View FIGURES 238 – 239. Basal apodeme ( Fig. 242View FIGURES 240 – 245) with diffuse anterior end, much widened. Proximal mesosome slender, elongated, overlapping with basal apodeme; anterior margin thickened. Gonopore ventral ( Fig. 243View FIGURES 240 – 245), widely open distally, with bifurcate distal ends ( Fig. 180View FIGURES 177 – 181). Mesosomal lobes fused distally, slender; 2 pmes on lateral margins of each lobe. Parameral heads ( Fig. 244View FIGURES 240 – 245) 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. 241View FIGURES 240 – 245. Abdominal chaetotaxy as in Table 2 and Fig. 239View FIGURES 238 – 239. Subgenital plate ( Fig. 245View FIGURES 240 – 245) funnel-shaped, reaching vulval margin. Vulval margin ( Fig. 245View FIGURES 240 – 245) with lateral marginal plates unconnected to subgenital plate (except on one side in one specimen). Vulval margin ( Fig. 245View FIGURES 240 – 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.
