title: Morphological characterization of the antennal sensilla of t he earwig Anisolabis maritima (Dermaptera: Carcinophoridae) with reference to their probable functions.
abstract: The earwig, Anisolabis maritima (Dermaptera: Carcinophoridae), is one of the most significant insects in KSA because, it was recorded in Saudi Arabia as a beneficial predator on eggs and newly hatched larvae of the red palm weevil, Rhyncophorus ferrugineus. We examined the external morphology of the antennal sensilla of males and females of A. maritima using scanning electron microscopy (SEM). The filiform antennae of A. maritima were of the conventional type comprising a basal scape, pedicle and a long, thread-like flagellum, which was composed of 12 flagellomeres of males and 16 flagellomeres of females. Six morphologically unique sensillar types were found and described on the antennae of males and females of A. maritima. Of those identified, there were three types of porous trichoid sensilla (long, curved and arcuate), and two types of basiconic sensilla (short and curved), and one type of aporous trichoid sensilla. The shape, external morphology and array of sensilla on the antennae of males and females of A. maritima were similar.
