释义 | BETA Examples of setaesetae isn’t in the Cambridge Dictionary yet. You can help! The surstyli are lateral and basal to the cerci, and also bear a tuft of long setae (fig. 5a-c). One important consequence of a possible brachiopod-annelid relationship is that the chitinous setae/chaetae may be homologous. Antennal setae are arranged in whorls, and are especially conspicuous in males. The dorso-lateral, lateral, and ventro-lateral regions of each segment are provided with a number of very small setae, anterior to the rings of spines. Fore wing basal fold with at least 2 and often several setae (fig. 4i). Submarginal vein with two setae on dorsal surface, these situated fairly near to each other near the middle of the costal cell. The cuticle is covered with minute, close-set papillae, and bears numerous setae, approximately 0-02 mm. in length, on both dorsal and ventral surfaces. Previous studies have found specific differences in the number of branches and length of clypeal setae in fourth instar larvae. Another, more linear tuft of long setae occurs near the inferior clasper (figs 5b and 7). The bases of the setae are no longer distinct but the spiracles appear as a lateral row of brownish spots. There are, on either side, three setae, associated with the frontal ring. |
