Description of Culicoides (Culicoides) bysta n. sp., a new member of the Pulicaris group (Diptera: Ceratopogonidae) from Slovakia

Table 4 Measurements of the most important female body characters. The mean and the range of values (minimum-maximum) are given for each character with the exception of the data for C. boyi from Denmark (DK), taken from Nielsen et al. [23]. P/H ratio is given as the reverse of H/P ratio

Significant differences (***P < 0.001 and *P < 0.05) between C. bysta n. sp. and C. pulicaris are indicated considering the cumulative data from Slovakia (SK) and France (FR). No differences within the species and between the countries, or between C. bysta n. sp. and C. boyi, were observed. Culicoides boyi and C. pulicaris were significantly different for the AtR ratio (P < 0.05)
