Main characters.

Body large, head slightly shorter than base of mesonotum in dorsal view. Rostrum extending to the posterior trochanter. Mesonotum black with following green markings: two large central obconical spots, three pairs of large greenish spots around them and pair of greenish spots on each lateral margin. Abdomen black; timbal cover ochraceous. Wings hyaline; fore wing with large fuscous spot at bases of apical cells second, third, fifth, and seventh; a marginal series of minute pale fuscous spots near apices of longitudinal veins to apical cells. Opercula in male broad, convex, extending to posterior margin of second abdominal segment, and overlapping; opercula in female smaller than those of male and broadly separated from each other. Aedeagus thick and curve ventrally, expended subapically, with a pair of sclerotized lateral processes apically as well as a pair of (membraneous) saccate hooks when everted.

Remarks.

After examining the holotype (male) of Oncotympana fuscata Distantpreserved in the Muséum National d’Histoire Naturelle (by MH) and investigating the intraspecific variability of Hyalessa maculaticollis , we reconfirm that Hyalessa fuscata is a junior synonym of Hyalessa maculaticollis , as previously proposed by several authors. Among the species of Hyalessa , Hyalessa maculaticollis has the widest range of distribution, from the Russian Maritime Territory, Korean Peninsula, Japan to China. This species mainly occurs in the forests, and the calling song of males is very loud with a complex transposition. Hyalessa maculaticollis is noted for its great intraspecific variability, including body size, markings on thorax, timbal cover, opercula and aedeagus, which has been recorded by Hayashi and Saisho (2011) based on materials collected from Japan. In this study, based on more materials collected from different locations in China, we further investigate the intraspecific variability of this species. For details, see below.

Intraspecific variability.

Body size. (1) Medium, about 30 mm in length (Fig. 6F); (2) Large, about 36 mm in length (Fig. 6A).

Coloration of body. (1) Generally black with green or ochreous markings (Fig. 6A, D, G, H); (2) Generally yellowish with dark ochreous markings (Fig. 6B); (3) Variegated (Fig. 6C, E, F).

Markings on mesonotum. (1) Mesonotum with 5 pairs of greenish spots: a pair of very small ones near anterior margin, three large spots on disc, and a pair of very lagre spots on lateral margins, (Fig. 6A, D); (2) Above mentioned 5 pairs of spots on mesonotum obscure or reduced (Fig. 6C, E, G, H); (3) Mesonotum with no distinct markings on disc (Fig. 6B, F).

Timbal cover. (1) Black (Fig. 6A, G, H); (2) Ochreous or greenish yellow, with dark ochreous to black patch on posterior area (Fig. 6C, D, F); (3) Dark ochreous or yellow (Fig. 6B, E).

Male opercula. (1) Black (Fig. 7A, H); (2) Light ochreous or brown (Fig. 7B, F); (3) Variegated (Fig. 7C, D, E, G).

Shaft of aedeagus. (1) Aedeagal shaft slightly S-shaped in lateral view (Fig. 8A, B, C, D, F, G); (2) Aedeagal shaft S-shaped in lateral view (Fig. 8E); (3) Aedeagal shaft C-shaped in lateral view (Fig. 8H).

Apex of aedeagus. (1) Paired saccate hooks much shorter than the sclerotized lateral processes (Fig. 8A, B, E); (2) Paired saccate hooks slightly shorter than the scle rotized lateral processes (Fig. 8C, D, F, G); (3) Paired saccate hooks much longer than the sclerotized lateral processes (Fig. 8H).
