Genus Pancola View in CoL new genus.
Type species: Pancola ailurus View in CoL new species.
Host distribution: Carnivora : Ailuridae .
Geographical range: Himalaya-Hengduan Mountains.
Diagnosis: Pancola is a new genus in the family of Trichodectidae . A dichotomous key by Lyal (1985) is used for the identification of Pancola with other genera in Trichodectidae . Based on the presence of exactly five abdominal spiracle openings, the abdominal chaetotaxy of both sexes, and the fact that the parameres are not fused to the lateral struts of the basal apodeme, Pancola is the closest to Paratrichodectes . However, these two genera can be separated by the following combination of characteristics: 1) the anterior head margin of the Pancola is broad, medium slightly convex, or non-convex, whereas the anterior of the head with osculum present in Paratrichodectes ( Lyal, 1985) ; 2) the head marginal temporal carina with rounded edges in Pancola , differentiate it from Paratrichodectes , which has a convex or rectangular temple margin ( Lyal, 1985); 3) the 6 pairs meso-metasternal setae present on Pancola , which is different from Paratrichodectes . There are no meso-metasternal setae on Paratrichodectes ( Lyal, 1985) ; 4) the male genitalia of Pancola has narrow mesomeres, which is absent in Paratrichodectes ( Lyal, 1985) .
Pancola can be morphologically distinguished from other Trichodectidae by the following combination of characters: 1) anterior head margin broad, medium slightly convex or non-convex; frons sclerotized; marginal carina (mc) along the head margin and partially pigmented; 2) sexual dimorphic antennae present, the male antennae stouter and larger than which on female; 3) thorax with long meso-metasternal setae present; meso-metasternal plate small, X-shaped; 4) abdomen with long setae present on tergites and sternites; five pairs of abdominal spiracles present on segments III-VII, small in size; 5) male subgenital plate present, sclerotised; mesomeres present, apices of mesomeres fused; parameres tapering, separate to each other; symmetric; small spinose sac present; basal apodeme elongated, straight but slightly diverging; and 6)
