Description

Female: Eyes bare and contiguous dorsally (Fig. 1a), length of contact divided by diameter of one ocellus = 1.5 ± 0.2. Length of antennal flagellum 746 ± 44 µm. Antennal ratio (AR: length of flagellomeres 9-13 divided by length of flagellomeres 1-8) 1.03 ± 0.04, number of sensilla coeloconica 14.71 ± 1.26. First flagellomere with 3.65 ± 0.24 sensilla coeloconica, long and slender (Fig. 1b). First flagellomere ratio (length divided by width) = 1.78 ± 0.07 (Fig. 1b). Maxillary palp ratio (PR: length/width of third palpal segment) = 2.9 ± 0.3 (Fig. 1c), P3/P2 (length of third palp segment divided by length of second) = 1.04 ± 0.11 (Fig. 1c). Numbers of mandibular and maxillary teeth = 15.1 ± 1.2 and 17.1 ± 1.4, respectively. Ratio of mandibular versus maxillar teeth (M/M) = 1.13 ± 0.10. Head height/proboscis length ratio (H/P) = 1.29 ± 0.07.

Wing length 1,641 ± 10 μm (Fig. 1d, e). The dark hourglass-shaped mark in the centre of cell r3 is broadest above the longitudinal fold above M1. Wing markings light brownish, distinct from the remaining, hyaline wing membrane. Cubital cell usually with a distinct spot (Fig. 1d, e; observed in about two thirds of the specimens), but this spot may be very small or entirely absent.

Two normal-sized spermathecae, ovoid, of almost equal size, with a short neck and a third rudimentary one (Fig. 1f).

Male: Unknown.

Etymology

Named as a tribute to Boy Overgaard Nielsen, an outstanding Danish entomologist and current emeritus at Aarhus University.

Distribution

Palaearctic - Denmark (northern Jutland).

Taxon discussion

The length divided by the width of the first flagellomere is significantly higher in C. boyi compared to all other Scandinavian species of this subgenus.
