Remarks

• Systematics: http://zoobank.org/AFE6A314-D608-4728-B3CD-BB3E2BFDF8EE Arctorthezia helvetica can be recognized by the following combination of characters: (i) 7-segmented antennae, (ii) dorsal triangle-shaped midthoracic setal plates hardly wider than long (iii) the proportion of simple pores and quadrilocular pores distal to vulva ca. 1:15, (iv) diamond-shape setal plate between mid-coxae on venter.(Szita, et al., 2015) Arctorthezia helvetica is closest to A. occidentalis in having 4 spine rows within the ovisac band and lacking circular pore clusters on the dorsum, but differs from A. occidentalis as follows (characters of A. occidentalis in brackets): (i) adult female body length less than 3 mm (adult female body length at least 3.5 mm); (ii) the fourth spine row within ovisac band weak (the fourth spine row within ovisac band strong); (iii) the proportion of simple pores to quadrilocular pores distal to vulva ca. 1:15 (the proportion of simple pores to quadrilocular pores distal to vulva ca. 1:6); (iv) dorsal triangle-shaped mid-thoracic setal plates hardly wider than long (dorsal triangleshaped mid-thoracic setal plates more than two times wider than long). (Szita, et al., 2015)
• Structure: Live adult female: dorsum with 9 pairs dorsal wax plates in each marginal row, 8 pairs in each submedian band, and 3 triangular or shield-shaped plates in middle of thorax. Ovisac short, about half length of body. (Szita, et al., 2015)
