new species

Priceiella (Camurnirmus) paulbrowni Gustafsson & Bush  , new species

( Figs 292–299View FIGURES 292 – 293View FIGURES 294 – 299)

Type host. Garrulax leucolophus diardi (Lesson, 1831)  —white-crested laughinthrush. Type locality. Phu Khiao , Chaiyaphum Province, Thailand. 

Other host. Garrulax leucolophus belangeri Lesson, 1831  —white-crested laughingthrush.

Diagnosis. The male genitalia of Priceiella (Camurnirmus) paulbrowni  n. sp. ( Figs 296–298View FIGURES 294 – 299) are intermediate between Pr. (Cm.) hwameicola  n. sp. ( Figs 288–290View FIGURES 287 – 291) and Pr. (Cm.) nipalensis  , and Pr. (Cm.) rhinocichlae ( Eichler, 1957)  . As in Pr. (Cm.) hwameicola  ( Fig. 289View FIGURES 287 – 291) and Pr. (Cm.) nipalensis  , the distal mesosome is rounded triangular in Pr. (Cm.) paulbrowni  ( Fig. 297View FIGURES 294 – 299), but as in Pr. (Cm.) rhinocichlae  the distal mesosome of Pr. (Cm.) paulbrowni  ( Fig. 297View FIGURES 294 – 299) is also dominated by a broad transversal thickening, and the parameres are almost as long as those of Pr. (Cm.) rhinocichlae  . In Pr. (Cm.) hwameicola  ( Fig. 289View FIGURES 287 – 291) and Pr. (Cm.) nipalensis  the distal thickening of the mesosomal lobes are more slender and not medianly continuous, and the parameres are much shorter. In both Pr. (Cm.) rhinocichlae  and Pr. (Cm.) paulbrowni  ( Fig. 296View FIGURES 294 – 299) the distal half of the basal apodeme is much wider than the proximal half, whereas in Pr. (Cm.) nipalensis  and Pr. (Cm.) hwameicola  ( Fig. 288View FIGURES 287 – 291) the basal apodeme is about equally wide in distal and proximal halves. In both Pr. (Cm.) rhinocichlae  and Pr. (Cm.) paulbrowni  ( Fig. 297View FIGURES 294 – 299), the horn-shaped lateral extensions of the gonopore originate from the proximal margin of the gonopore, whereas in Pr. (Cm.) hwameicola  ( Fig. 289View FIGURES 287 – 291) these extensions originate from the lateral margins of the gonopore.

Priceiella (Camurnirmus) paulbrowni  can be separated from Pr. (Cm.) rhinocichlae  by the following characters: distal mesosome quadratic in Pr. (Cm.) rhinocichlae  but rounded triangular in Pr. (Cm.) paulbrowni  ( Fig. 297View FIGURES 294 – 299); parameres with characteristic notch on lateral margin about 1/3 from distal tip associated with pst 2 in Pr. (Cm.) rhinocichlae  , but parameres without such notch in Pr. (Cm.) paulbrowni  ( Fig. 298View FIGURES 294 – 299); gonopore longer than wide in Pr. (Cm.) rhinocichlae  , but wider than long in Pr. (Cm.) paulbrowni  ( Fig. 297View FIGURES 294 – 299). Vulval chaetotaxy partially overlapping between Pr. (Cm.) rhinocichlae  an Pr. (Cm.) hwameicola  ( Fig. 299View FIGURES 294 – 299), but Pr. (Cm.) rhinocichlae  has 5– 7 vss [7–9 in Pr. (Cm.) hwameicola  ]. Females of Pr. (Cm.) rhinocichlae  lack the psps of tergopleurite VIII present in Pr. (Cm.) paulbrowni  ( Fig. 293View FIGURES 292 – 293) and Pr. (Cm.) hwameicola  ( Fig. 286View FIGURES 285 – 286), but have ps on segment III, which are absent in Pr. (Cm.) paulbrowni  and Pr. (Cm.) hwameicola  .

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 294View FIGURES 294 – 299. Dorsal preantennal suture absent. Only marginal carina, mandibles, head nodi, and gular plate with dark pigmentation. Thoracic and abdominal segments as in genus and subgenus descriptions and Figs 292–293View FIGURES 292 – 293. Lateral tergopleurites and pleural incrassations as in Fig. 316View FIGURES 315 – 318.

Male. Abdominal chaetotaxy as in Table 2 and Fig. 292View FIGURES 292 – 293. Antero-lateral ends of subgenital plate as in Fig. 292View FIGURES 292 – 293. Basal apodeme narrows anteriorly ( Fig. 296View FIGURES 294 – 299), with modest lateral expansion. Proximal mesosome rectangular. Gonopore ( Fig. 297View FIGURES 294 – 299) broader than long, narrowly open distally. Mesosomal lobes broad, fused distally; 2 ames sensilla on each side anterio-lateral to gonopore ( Fig. 297View FIGURES 294 – 299). Parameral heads ( Fig. 298View FIGURES 294 – 299) irregular. Parameral blades long, tapering, widely divergent distally; pst1–2 sensilla.

Etymology. The species epithet is in honour of Paul Brown, Senior Curator of Sternorrhyncha, lice, and thrips at the NHMLAbout NHML. His monumental efforts in loaning large numbers of specimens made this revision possible.
