Description

Female: Eyes bare and contiguous dorsally (Fig. 3a), length of contact contact divided by diameter of one ocellus = 1.2 ± 0.3. Length of antennal flagellum 646 ± 14 μm. Antennal ratio (AR: length of flagellomeres 9-13 divided by length of flagellomeres 1-8) 1.13 ± 0.04, number of sensilla coeloconica 10.70 ± 0.82. First flagellomere with 3.0 ± 0.0 sensilla coeloconica. First flagellomere ratio (length divided by width) = 1.46 ± 0.06. Maxillary palp ratio (PR: length/width of third palp segment) = 2.9 ± 0.2 (Fig. 3c), P3/P2 (length of third palp segment divided by length of second) = 0.87 ± 0.08 (Fig. 3c). Numbers of mandibular and maxillary teeth = 12.8 ± 0.6 and 14.9 ± 1.5, respectively. Ratio of mandibular vs. maxillary teeth (M/M) = 1.17 ± 0.12. Head height/proboscis length ratio (H/P) = 1.29 ± 0.07.

Wing length 1,423 ± 39 μm (Fig. 3d, e). The shape of the dark hour-glass formed mark in the middle of r3 is broadest above the longitudinal fold above M1. The dark areas on the wings are extensive and surrounding vein M1 and M2. Wings have a large dark spot in cell cu, which is separated from the dark areas bordering Cu1 and Cu2 (Fig. 3d, e).

Two functional spermathecae, ovoid, of almost equal size, with a short neck; a third rudimentary one present (Fig. 3f).

Male: Unknown.

Etymology

The species epithet refers to the municipality Kalix in northern Sweden, in which the type series was collected.

Distribution

Palaearctic - Sweden (Norrbotten).

Taxon discussion

Culicoides kalix could be confused with C. selandicus but may be separated from this as already discussed above under the description of the latter species and as outlined in the key.
