Description

Dilyta subclavata Förster, 1869

Fig. 6.6

Dilyta subclavata Förster, 1869: 338. Type: deposited in NMW (examined).

Alloxysta (Alloxysta) subclavata – Dalla Torre & Kieffer 1910: 255.

Dilyta subclavata – Hellén 1963: 5.

Diagnosis

Dilyta subclavata is mainly characterized by a punctate area on the posterior part of the metasoma; female antenna slightly clavate from F6 with F1 slightly shorter than or subequal to pedicel, F2 subequal to F3, F4 slightly shorter than F1 but longer than F2 and F3, and sensilla beginning on F6–F7 (Fig. 6.6); male antenna slightly clavate from F4 with F1 slightly longer than pedicel and sometimes slightly arched, F2 shorter than F1 and F3, F3 shorter than F1, F1 subequal to F4, F4–F12 wider than previous segments, and sensilla beginning on F4. It is similar to D. longinqua, but can be differentiated by the proportions of the flagellomere (F1 is subequal to pedicel or slightly longer, F2 is shorter than F3, F3 is shorter than F4, antenna are slightly clavate from F6, and sensilla begin on F 6 in D. longinqua females (Fig. 6.3), while F1 is subequal to pedicel, F2 is shorter than F1 or F3, F3 is subequal to F1, F3–F12 are wider than the previous flagellomeres, antenna are slightly clavate from F3, and sensilla begin on F 3 in males of D. longinqua).
