Diagnosis.

Body length 1.5–2.0 mm. Cuticle coated in dark, sandy gray, and white scales in contrasting pattern. Funicle with six articles. Procoxae contiguous. Only odd-numbered elytral intervals with recumbent scales. Erect elytral scales evenly distributed, not concentrated in bundle. Femora without ventral teeth. Scutellum reduced. Aedeagus short, with two sclerotized structures apico-laterally (one on each side) in internal sac. Prosternal cavity prominent and with steep lateral ridges. Metaventrite with a distinct elevated transverse ridge separating the meta- and mesocoxae (Fig. 18 A View Figure 18 ). Metatibial uncus simple in both sexes (Fig. 1 E – H View Figure 1 ). Aedeagus weakly tapering in apical half, and evenly curved in lateral view (Fig. 15 C, D View Figure 15 ). Internal sac lacking prominent basal protruding structure (Fig. 15 C, D View Figure 15 ).

Distribution.

This species is currently known from the Izu Islands (Miyake Is., Hachijo-jima Is., Aogashima Is.), Nagasaki Prefecture, Fukui Prefecture, Kagoshima Prefecture (Nakanoshima), and the Ryukyu Islands (Okinawa Is., Ishigaki Is., Yonaguni Is.) ( Kojima and Morimoto 2004; Lewis and Yoshitake 2022). The A. distinctus records from Taiwan in Alonso-Zarazaga et al. (2023) and Kojima and Morimoto (2004) are more likely A. taiwanus as no specimens of A. distinctus were encountered in examined collections.

Comments.

Fujii et al. (2012) reared A. distinctus from the galls of Asteralobia sasakii (Monzen, 1937) on Ilex crenata Thunb. var. hachijoensis Nakai, and Kojima (2013) reared specimens from the galls of A. sasakii on Ilex integra Thunb. Kojima (2014) also collected 50 specimens from Boehmeria sp. on Kuchinoerabu-jima Island. On Okinawa Island, specimens of A. distinctus were only collected from Oku, Yambaru National Park ( Lewis and Yoshitake 2022) despite several years of continuous, year-long malaise trapping at 24 sites (3 traps per site) across the island. This suggests that A. distinctus is sensitive to anthropogenic disturbance and, coupled with the apparent cecidophagous habits of the species, may be the reason for its relative rarity in collections.
