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 296–298 ) are intermediate between Pr . ( Cm. ) hwameicola n. sp. ( Figs 288–290 ) and Pr . ( Cm. ) nipalensis , and Pr . ( Cm. ) rhinocichlae ( Eichler, 1957 ) . As in Pr . ( Cm. ) hwameicola ( Fig. 289 ) and Pr . ( Cm. ) nipalensis , the distal mesosome is rounded triangular in Pr . ( Cm. ) paulbrowni ( Fig. 297 ), but as in Pr . ( Cm. ) rhinocichlae the distal mesosome of Pr . ( Cm. ) paulbrowni ( Fig. 297 ) 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. 289 ) 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. 296 ) the distal half of the basal apodeme is much wider than the proximal half, whereas in Pr . ( Cm. ) nipalensis and Pr . ( Cm. ) hwameicola ( Fig. 288 ) the basal apodeme is about equally wide in distal and proximal halves. In both Pr . ( Cm. ) rhinocichlae and Pr . ( Cm. ) paulbrowni ( Fig. 297 ), the horn-shaped lateral extensions of the gonopore originate from the proximal margin of the gonopore, whereas in Pr . ( Cm. ) hwameicola ( Fig. 289 ) 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. 297 ); 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. 298 ); gonopore longer than wide in Pr . ( Cm. ) rhinocichlae , but wider than long in Pr . ( Cm. ) paulbrowni ( Fig. 297 ). Vulval chaetotaxy partially overlapping between Pr . ( Cm. ) rhinocichlae an Pr . ( Cm. ) hwameicola ( Fig. 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. 293 ) and Pr . ( Cm. ) hwameicola ( Fig. 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. 294 . Dorsal preantennal suture absent. Only marginal carina, mandibles, head nodi, and gular plate with dark pigmentation.

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

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