Priceiella (Camurnirmus) hwameicola Gustafsson & Bush , new species

( Figs 285–291 , 316 )

Type host. Garrulax taewanus Swinhoe, 1859 — Taiwan hwamei. Type locality. Tientzu , Taiwan.

Diagnosis. Priceiella (Camurnirmus) hwameicola n. sp. is most similar to Pr. (Cm.) nipalensis ( Ansari, 1956a) and Pr. (Cm.) paulbrowni n. sp., with differences being mainly in the male genitalia. In all three species, the distal mesosome is rounded triangular ( Figs 289 , 297 ), the proximal mesosome is at least as long as wide [longer than wide in Pr. (Cm.) nipalensis ], and the parameres are at most twice as long as the mesosome ( Figs 288 , 296 ). However, the mesosome is broader and with more complicated border thickening in Pr. (Cm.) hwameicola ( Fig. 289 ) than in Pr. (Cm.) nipalensis , with the mesosome of Pr. (Cm.) hwameicola being almost twice at broad as the proximal mesosome at the height of the gonopore, whereas in Pr. (Cm.) nipalensis the mesosome is less than twice as broad as the proximal mesosome at the same place. The parameres of Pr. (Cm.) nipalensis are convergent distally, and not widely divergent as in Pr. (Cm.) hwameicola . The gonopore of Pr. (Cm.) nipalensis lack the hornshaped lateral extensions present in Pr. (Cm.) hwameicola . Females separated by vulval chaetotaxy, with Pr. (Cm.) nipalensis having 5 vms [3 in Pr. (Cm.) hwameicola ], but vos and vss overlap.

For differences between Pr. (Cm.) hwameicola and Pr. (Cm.) paulbrowni , see Pr. (Cm.) paulbrowni , below.

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 287 . Minute dorsal preantennal suture present mainly in females surrounding dsms. Antennae monomorphic. Only lateral parts of marginal carina, preantennal nodi, and preocular nodi darkly pigmented. Thoracic and abdominal segments as in genus and subgenus descriptions and Figs 285–286 . Lateral tergopleurites and pleural incrassations Fig. 316 .

Male. Abdominal chaetotaxy as in Table 8 and Fig. 285 . Subgenital plate as in Fig. 285 . Antero-lateral end of basal apodeme modestly expanded ( Fig. 288 ). Proximal mesosome broad, rectangular. Gonopore ( Fig. 289 ) ventral, open distally. Mesosomal lobes wide, fused distally; 1 pmes sensilla on each side antero-lateral to gonopore; 2 ames microsetae on each side lateral to pmes, located on lateral ridges of mesosomal lobes. Parameral heads ( Fig. 290 ) roughly rectangular. Parameral blades tapering, somewhat elongated, widely divergent distally; pst1–2 sensilla. Measurements ex Garrulax taewanus (n = 4): TL = 1.44–1.50; HL = 0.36–0.39; HW = 0.36–0.39; PRW = 0.21–0.23; PTW = 0.35–0.37; AW = 0.51–0.55.

Female. Abdominal chaetotaxy as in Table 8 and Fig. 286 . Subgenital plate roughly triangular ( Fig. 291 ), reaching vulval margin and there flaring into cross-piece. Vulval margin ( Fig. 291 ) gently rounded, with 3 slender vms on each side, and 7–8 thorn-like vss on each side; 4–6 slender vos on each side; distal 2 vos near, but not median to, vss. Measurements ex Garrulax taewanus (n = 7): TL = 1.66–1.83; HL = 0.38–0.41; HW = 0.39–0.43; PRW = 0.22–0.25; PTW = 0.36–0.40; AW = 0.54–0.60.

Etymology. The species epithet is derived from the Chinese “huàméi” for “thrush”, on which the vernacular name “ Taiwan hwamei ” is based, combined with Latin “ -cola ” for “inhabitant”.
