Morphological revision of the hyperdiverse Brueelia - complex (Insecta: Phthiraptera: Ischnocera: Philopteridae) with new taxa, checklists and generic key Bush, Sarah E. Zootaxa 2017 2017-08-31 4313 1 1 443 Gustafsson & Bush Bush 2017 [151,638,1700,1726] Insecta Philopteridae Aratricerca Animalia Phthiraptera 108 109 Arthropoda species cirithra sp. nov.    Typehost.  Ptiloprora guisei guisei(De Vis, 1894)— rufous-backed honeyeater.    Typelocality.  12 milesS of Edie Creek, elev.  2405 m, Bulldog Road, MorobeDistrict, Papua New Guinea.   Diagnosis.  Aratricerca cirithra  n. sp.is superficially similar to members of  Turdinirmus, with which it shares the following characters: dorsal preantennal suture reaches adsand dsms; ventral anterior plate present; parameral blades irregularly oval; female subgenital plate approaches vulval margin, but does not flare. However, pnsand posare absent in  Aratricerca  n. gen.( Fig. 170) but present in  Turdinirmus( Figs 184, 191), and while the dorsal preantennal suture interrupts the lateral margin of the head in  Ar. cirithra, this is not the case in  Turdinirmus. Abdominal chaetotaxy is similar between the two genera, but psand absent on segment III in  Turdinirmus, but present in  Ar. cirithra( Table 2). For differences between  Aratricercaand the morphologically similar  Turdinirmoides  n. gen., see genus description.   Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 170. Dorsal preantennal suture in some specimens medianly continuous, but section median to adsconsiderably narrower than lateral sections; this may be a mounting issue. Ventral anterior plate diffuse posteriorly. Ventral carinae with fingers protruding into clypeo-labral suture, in some specimens with distinct thickening medianly. Thickening on lateral section of dorsal anterior plate may be remnants of marginal carina. Preantennal head darker than postantennal head. Thoracic and abdominal segments as in genus description and Figs 168–169. Sternal plates and median section of tergopleurites translucent; lateral tergopleurites and pleurites with dark brown pigmentation. Pleurites interlock to form “rails” along abdominal sides.   Male. Only sternal plate II with antero-lateral thickening ( Fig. 168). Abdominal chaetotaxy as in Table 2and Fig. 168. Dorsal setae on tail absent in some specimens, including holotype. Basal apodeme ( Fig. 171) bluntly oval. Proximal mesosome bulbous. Gonopore ( Fig. 172) as subparallel, sublateral hook-shaped sclerites, open distally and proximally. Mesosomal lobes with angular process at about half-length; distal to this hyaline discs with diffusely rugose distal margins; 2 pmesvisible on each lobe lateral to gonopore. Parameral heads ( Fig. 173) narrow, bifid. Parameral blades lobe-like; pst1sensillus, located centrally in distal part; pst2absent. Measurements ex  Ptiloprora guisei guisei(n = 3 except n = 2 for AW): TL = 2.30–2.40; HL = 0.41–0.43; HW = 0.36–0.37; PRW = 0.25–0.28; PTW = 0.25–0.28; AW = 0.40–0.46.  Female. Sternal plates II–III with antero-lateral thickenings, more prominent on sternal plate II ( Fig. 169). Abdominal chaetotaxy as in Table 2and Fig. 169. Subgenital plate ( Fig. 174) rectangular with distal median process that approaches but does not reach vulval margin. Vulval margin ( Fig. 174) gently rounded, with 5–6 short, slender vmson each side, and 7–9 short, thorn-like vsson each side; 5–7 long, slender vos; distal 2–3 vosmedian or even distal to vss. Measurements ex  Ptiloprora guisei guisei(n = 9 except n = 7 for TL and n = 6 for AW): TL = 2.56–2.80; HL = 0.41–0.45; HW = 0.36–0.41; PRW = 0.25–0.29; PTW = 0.26–0.30; AW = 0.40–0.51.   Etymology.The species epithet is derived from Greek “ kiríthra” for “honeycomb”, but Latinized. This refers to the shape of the pterothorax.     Typematerial. Ex   Ptiloprora guisei guisei: Holotype ♂,  12 milesS of Edie Creek, elev.  2405 m, Bulldog Road, MorobeDistrict, Papua New Guinea,  3 Jul. 1966, J.
