Priceiella (Camurnirmus) lindquistae Gustafsson, Clayton , & Bush, new species

( Figs 57–63 )

Type host. Ianthocincla chinensis chinensis (Scopoli 1786) —black-throated laughing-thrush ( Leiothrichidae ).

Type locality. Shiwandashan National Park , Guangxi Province, China.

Diagnosis. Priceiella (Camurnirmus) lindquistae n. sp. is closely related to P. (C.) sonorae n. sp., with which it shares the following characters: female subgenital plate with medial reticulation ( Figs 63 , 70 ); parameres elongate and widely diverging distally ( Figs 62 , 69 ); antennae sexually dimorphic ( Figs 57–58 , 64–65 ); dorsal preantennal suture absent ( Figs 59 , 66 ); no tps on female tergopleurite VIII ( Figs 58 , 65 ). These two species can be separated on the following characters: ps present on female abdominal segment III in P. (C.) lindquistae ( Fig. 58 ) but absent in P. (C.) sonorae ( Fig. 65 ); basal apodeme barely or not constricted at mid-length in P. (C.) lindquistae ( Fig. 60 ), but with considerably constriction at mid-length in P. (C.) sonorae ( Fig. 67 ); gonopore long and slender with long anterior projection and hook-shaped distal ends in P. (C.) lindquistae ( Fig. 61 ), but short and broad with short anterior projection and without hooks in P. (C.) sonorae ( Fig. 68 ); proximal mesosome gently rounded in P. (C.) lindquistae ( Fig 61 ) but more angular in P. (C.) sonorae ( Fig. 68 ); parameres much longer in P. (C.) lindquistae ( Fig. 62 ) than in P. (C.) sonorae ( Fig. 69 ); pst1–2 close together in P. (C.) sonorae ( Fig. 69 ), but widely separated in P. (C.) lindquistae ( Fig. 62 ); female subgenital plate more constricted at base of cross-piece in P. (C.) sonorae ( Fig. 70 ) than in P. (C.) lindquistae ( Fig. 63 ), but vulval chaetotaxy overlaps between these two species.

Description. Both sexes. Head pentagonal ( Fig. 59 ). Frons broad, concave. Dorsal preantennal suture absent. Head chaetotaxy as in Fig. 59 . Antennae sexually dimorphic. Base pigmentation pale yellowish brown; marginal and marginal temporal carinae, head nodi, proepimera, metepisterna and pleural incrassations dark, slightly reddish, brown; gular plate, margins of antennal sockets, sternal plates IV–VI, subgenital plates and lateral sections of tergopleurites medium brown; metasternum and sternal plates II–III pale brown.

Male. Scape swollen and elongated ( Fig. 59 ). Pteronotum with 7–9 mms on each side. Abdominal plates and chaetotaxy as in Fig. 57 . Male genitalia as in Figs 60–62 . Basal apodeme roughly rectangular, barely or not expanded in anterior end ( Fig. 60 ). Proximal mesosome broad, gently rounded ( Fig. 61 ). Mesosomal lobes comparatively slender. Marginal thickening of mesosomal lobes deeply sinuous laterally, not medially continuous. Gonopore longer than broad, with long, slender proximal projection. Distal ends of gonopore hook-like; 2 ames microsetae on each side antero-lateral to gonopore; 1 pmes sensillus on each side on distal hooks of gonopore; 2 pmes microsetae on each side on lateral margins of mesosome. Parameral heads with sinuous margins and medioposterior bulge ( Fig. 62 ). Parameral blades very long, tapered, highly divergent; pst1–2 widely separated. Measurements ex Ianthocincla chinensis chinensis (n = 2): TL = 1.44–1.48; HL = 0.37; HW = 0.38–0.39; PRW = 0.23–0.24; PTW = 0.38; AW = 0.60.

Female. Scape as in Fig. 58 . Pteronotum with 5 mms on each side. Abdominal plates and chaetotaxy as in Fig. 58 . Subgenital plate with dense reticulation ( Fig. 63 ). Vulval margin ( Fig. 63 ) gently rounded, with 3–4 long, slender vms on each side (medial-most vms on each side shorter than others) and 6–7 short thorn-like vss on each side; 3–4 long, slender vos on each side; distal vos near vss. Measurements ex Ianthocincla chinensis chinensis (n = 2): TL = 1.70–1.71; HL = 0.39; HW = 0.40–0.41; PRW = 0.22–0.24; PTW = 0.35–0.37; AW = 0.53–0.54.

Etymology. The species epithet is in honor of Emelie Lindquist (University of Gothenburg, Gothenburg, Sweden), in recognition of her assistance in collecting lice in Sweden during DG’s PhD studies.
