scolopalen.

1912 J. H. Comstock Spider Bk. iii. 169 The failure of other observers to discover scolopalæ or auditory pins..has made this conclusion doubtful.

1917 Ann. Entomol. Soc. Amer. X. 69 Its distal portion penetrates the center of the enveloping cell into the proximal end of the cap cell, where the nerve enlarges to form the peg-shaped body or scolopale.

1925 A. D. Imms Gen. Textbk. Entomol. i. 82 An auditory or chordotonal sensilla consists of a nerve end-organ or scolophore, enclosing a hollow peg-like structure or scolopale.

1932 Parasitology XXIV. 457 These cells are connected with the main antennal nerve, whereas the other end gives off a long scolopala, or the sense rod.

1948 Sci. News 7 19 One finds in all insects structures which consist of parallel elements—elongated spindle-shaped sensory cells whose axes are prolonged into nerve fibres on the central side while on the other side they are in contact with the so-called ‘scolopales’ (pointed stakes).

1964 R. M. Fox & J. W. Fox Introd. Compar. Entomol. vi. 193 The unit of the chordotonal organ is the scolopophore.., composed of an apical cap cell attached to the body wall and an envelope cell; in the central part of the cap cell is a terminal ligament which forms a functional extension of the sensory rod (scolops or scolopale) in the envelope cell.

1969 R. F. Chapman Insects xxx. 630 The most fully studied contact chemoreceptors are the trichoid sensilla on the legs and mouth~parts of Phormia. They are from 30 to 300 μ long. From the tip the scolopale is invaginated.

1978 H. V. Daly et al. Introd. Insect Biol. & Diversity vi. 107/2 In the usual arrangement [of sensilla], the dendrite of a single bipolar neuron is attached to a movable part of the body, often by a minute cuticular sheath called a scolopale.
