FIGURE 2. Male terminalia. Dissected parts from D in Drosophila (Sophophora) carrolli n. sp., a new species from Brunei, closely related to Drosophila (Sophophora) rhopaloa Bock & Wheeler, 1972 (Diptera: Drosophilidae)

FIGURE 2. Male terminalia. Dissected parts from D. carrolli (A, C, E, G) or D. rhopaloa (B, D, F, H). (A, B) epandrium in dorsal view. Note the differences in sensory bristle length and distribution (blue ovals and arrowheads) as well as genital comb size (blue arrows) between species. The epandrium is always darker overall in D. carrolli. Phallus in ventral view (C, D) and side view (E, F). The phallus conformation in D. carrolli (C, E) is similar to that of D. rhopaloa (D, F), but shows quantitative difference in size and appears sturdier. The looping of the aedeagus base is more open in D. carrolli than in D. rhopaloa (blue double-arrows). (G, H), testes of D. carrolli (G) and D. rhopaloa (H) have similar shapes and coiling, but they appear bigger in D. carrolli, and show a characteristic bright yellow color compared to the dull yellow testes of D. rhopaloa.
