Differential diagnosis. Arhaphe breviata differs from A. arguta by its smaller size (body length: A. breviata — 3: 7.24 mm, Ƥ: 8.69 mm; A. arguta —3: 8.69–9.34 mm, ƤƤ: 9.61–10.04 mm), and narrower head (width of head including eyes: A. breviata —3: 1.84 mm, Ƥ: 2.00 mm; A. arguta —3: 2.05–2.29 mm, ƤƤ: 2.32–2.51 mm). In A. breviata the inner margin of corium is white with a row of black punctures (Fig. 11), while in A. arguta it is narrowly bordered with black (Figs. 8–9). In A. brevita the silvery pubescence of the abdominal ventrites IV–VI is missing anterolaterally in the form of a large oval patch (Fig. 12), whereas in A. arguta the ventrites are covered with continuous silvery pubescence except only small triangular patches in the anterolateral angles (Fig. 10). (See also Key above).
