Diagnosis

Urostylis hubeiensis can be distinguished from other species of the genus using a combination of the following characteristics (cf. Kim et al. 2018, Zhou and Rédei 2018): dorsum pale, mostly concolorously punctate (Fig. 1 View Figure 1 D and Fig. 8 View Figure 8 ); scape (antennal segment I) with a black longitudinal fascia on lateral surface (Fig. 2 View Figure 2 D); scutellum with pale punctures entirely; forewing decorated with large, coarse, scattered black punctures in area enclosed by medial furrow and Cu (cubital) vein (relatively sparse between Cu and R+M (radiomedial) veins, denser between R+M and medial furrow); corium with a series of rather regularly arranged, closely placed black punctures forming a straight line along claval furrow; abdomen with pale spiracles (Fig. 3 View Figure 3 D); genital capsule of male with a pair of short and blunt dorsolateral processes and a single apically excised ventromedian process (Fig. 4 View Figure 4 D, Fig. 5 View Figure 5 D and Fig. 6 View Figure 6 D); posterior margin of genital capsule below dorsolateral process broadly convex, enclosing a narrow, U-shaped interspace with anterior margin of ventromedian process in lateral view; ventromedian process directed nearly dorsad, with apex approximately reaching level of dorsolateral processes in lateral view, with lateral margins subparallel-sided or slightly concave in caudal view; ventrite VII of female not protruding posteriad below ovipositor, leaving valvifers VIII fully exposed (Fig. 7 View Figure 7 D); laterotergite VIII of female reaching a level of laterotergite IX ventrally; laterotergite IX of female longer, distinctly surpassing posterior extremities of valvifers VIII both in ventral, but particularly in posteroventral views; and posteromesal portion of laterotergite IX surpassing its posterolateral portion posteriorly.

Distribution

Japan (Tsushima Island) (Fig. 9 View Figure 9 ), China ( Ren 1997, Zhou and Rédei 2018), Korea ( Kim et al. 2018, Zhou and Rédei 2018).

The records of Urostylis hubeiensis from Tsushima Island represent the easternmost occurrence of this species.

Biology

Urostylis hubeiensis was collected from Quercus acutissima Carruth. ( Fagaceae ) in Japan, suggesting that this deciduous fagaceous tree is a host plant for this species. In other distribution areas, the host plant of this urostylidid species is unknown. Uros. hubeiensis is found in broad-leaved forests in Japan. Its habitat is unknown in China, but it is found regularly in forest of Q. acutissima in Korea (M. Roca-Cusachs, pers. comm. 2022). In Korea, Uros. hubeiensis were attracted to artificial light ( Kim et al. 2018).

Adults were collected in May, June, September and November in Japan and from May to September in other distribution areas ( Ren 1997, Kim et al. 2018, Zhou and Rédei 2018). The nymph and overwintering stages are unknown both in Japan and in other distribution areas.

Taxon discussion

The above-recorded specimens matched the photographs of the holotype ( Zhou and Rédei 2018) and descriptions ( Ren 1997, Kim et al. 2018, Zhou and Rédei 2018) of Urostylis hubeiensis described from China in terms of their morphological characteristics. Moreover, the Japanese specimens were identified as Uros. koreana [= Uros. hubeiensis ] using a key for the Korean species of Urostylis ( Kim et al. 2018). In conclusion, we identified the Japanese specimens as Uros. hubeiensis .
