| Summary: | Key to the species of Diaulota from the world (Updated and revised from Ahn, 1996; Song et al. , 2018; Yoo and Ahn, 2021. Note that dissections of the male genitalia are essential for correct species identification.) 1. Body black, rarely dark reddish brown. 2 – Body brown to reddish brown. 7 2. Hypomeron without longitudinal carina, more angulated posteriorly; mentum with deeper anterior emargination; median lobe (fig. 36 in Ahn, 1996). D. pacifica – Hypomeron with longitudinal carina, less angulated posteriorly; mentum with shallower anterior emargiantion. 3 3. Elytron wider than long; posterior margin of male sternite VIII crenate; median lobe (fig. 26 in Ahn, 1996). D . fulviventris – Elytron longer than wide; posterior margin of male sternite VIII smooth. 4 4. Anterior margin of labrum not truncated; median lobe (fig. 7 in Ahn, 1996); distributed in the NE Pacific coasts. D. densissima – Anterior margin of labrum truncated; distributed in the NW Pacific coats and Alaska. 5 5. Pronotum and elytra without distinctively long filiform setae; mandible not pointed; median lobe (fig. 22 in Ahn, 1996). D. alaskana – Pronotum and elytra with distinctively long filiform setae; mandible more or less pointed. 6 6. Median lobe (fig. 21 in Ahn, 1996); distributed in Korea and Honshu (Japan). D. aokii – Median lobe (figs. 3–4 in Song et al. , 2018); distributed in Hokkaido (Japan), Kamchatka (Russia), and USA (Alaska). D. hokkaidona 7. Labrum large and robust; mandible more elongate; labial palpi with 3 distinct articles; ligula with 2 minute setae; metum with shallower anterior emargination; tarsal formula 4-4-4. 8 – Labrum not large and robust; mandible less elongate; labial palpi with 3 indistinct articles; ligula without minute setae; metum with deeper anterior emargination; tarsal formula 3-3-4 or 4-4-5. 9 8. Antennomeres 6–10 subquadrate; anterior margin of labrum truncated; labial palpomere 1 as wide as 2; median lobe smaller; apical process of median lobe broader; apical internal sclerite rounded (fig. 10L in ... |
