Yang, Lin & Chen, Xiang-Sheng, 2014, Three new bamboo-feeding species of the genus Symplanella Fennah (Hemiptera, Fulgoromorpha, Caliscelidae) from China, ZooKeys 408, pp. 19-30 : 22-23

Symplanella hainanensis sp. n. Figs 13-24

Measurements.

Body length including forewing: male 5.45-5.62 mm (N = 2), female 6.00-6.30 mm (N = 8); forewing length: male 4.40 mm (N = 2), female 4.65-4.95 mm (N = 8).

Coloration.

General color dirty yellowish brown. Ocelli reddish brown, eyes black brown. Antennae with one black spot at apex of second segment. Frons and clypeus mostly dark brown. Central area of vertex and pronotum, base of mesonotum with somewhat pale yellowish red. Procoxae, mesocoxae, metapleura, abdominal sternites laterally and pregenital sternite of female, fuscous.

Head and thorax.

Vertex including eyes as wide as pronotum. Vertex longer in middle line than broad at base (1.24:1). Frons 1.67 times longer in middle line than widest part. Pronotum shorter in middle line than vertex (0.74:1). Mesonotum 0.87 times as long as vertex and pronotum together in middle line. Forewing longer in middle line than broad at widest part (4.00:1).

Abdomen.

Anal segment of male in dorsal view (Fig. 18) with median part slightly widened; in lateral view (Fig. 19) broad at basal half, abruptly narrowed at apical half, apex acute, with some micro teeth at apical ventral margin. Pygofer in lateral view (Fig. 20) with dorsal margin distinctly shorter than ventral margin, posterior margin sinuate, one finger-like process at dorsal third. Genital style in lateral view (Fig. 21) broad and rounded, dorsal margin concave, dorsal half of posterior margin mound-like, covered with a lot of micro teeth; in posterior view (Fig. 22) short and stout, mostly oval, dorsal angle forked, covered with a lot of micro teeth. Aedeagus in dorsal view (Fig. 23) with basal half broad, apical half abruptly narrowed, stick-like, each side with one spine-like process at widest part; in lateral view (Fig. 24) with base broad, narrowing apically, aedeagal shaft slightly curved ventrad. Connective in lateral view (Fig. 24) curved ventrad, fused with base of aedeagus, nearly forming Y-shape.

Type material.

Holotype: ♂, China: Hainan, Diaoluoshan National Natural Reserve (18°47'N, 109°52'E), on bamboo, 9-12 Apr. 2009, X.-H. Hou; paratypes: 1 ♂, 8 ♀♀, data same as holotype.

Host plant.

Bamboo.

Distribution.

South China (Hainan) (Fig. 37).

Remarks.

This new species is similar to the type species from Burma, Symplanella breviceps Fennah, 1987, but can be distinguished from the latter in: i) frons mostly dark brown (stramineous in Symplanella breviceps ); ii) vertex with anterior margin rounded (angulated in Symplanella breviceps ); iii) posterior margin of pygofer with one spinous process dorsally (absent in Symplanella breviceps ); iv) genital style in posterior view broad and short (narrow and long in Symplanella breviceps ).

Etymology.

The new species is named after the type locality, Hainan Province, China.
