Anelytra hainanensis Shi sp. nov.

Figure 1

Description. Male. Body medium, slightly cylindrical. Head short and stout, conical. Fastigium verticis conical, robust and short, projecting forward, apex obtusely rounded. Frontal verticis inclined, subrugose, with numerous impressed spots. Eyes globular, protruding.

Pronotum cylindrical, anterior margin rounded, posterior margin comparatively straight, or slightly concave; the transversal sulci indistinct; lateral lobes longer than deep, humeral sinus comparatively distinct, shallow.

Procoxa with 1 spine; profemur with 2–3 spines on inner margin and 1–3 spines on outer margin of ventral surface; protibia with 7 spines on inner and outer margins of ventral surface separately; tibial tympanal organs narrow, rimiform. Mesofemur without spines on inner margin of ventral surface, wth 8 spines on outer margin of ventral surface; mesotibia with 7 spines on inner and outer margins of ventral surface separately. Postfemur without spines on inner margin, and with 8–9 spines on outer margin of ventral surface; apices of genicular lobes rounded; posttibia with 8–9 spines on inner margin, and 6–7 spines on outer margin of ventral surface; bearing two pairs of ventral apical spurs and one pair of dorsal apical spurs.

Tegmina short, surpassing posterior margin of pronotum, reaching middle area of first abdominal tergite, apices rounded. Hind wings absent.

Tenth abdominal tergite with basal area broad, apical area narrower, curved downwards, apex rounded, apical half with a middle longitudinal furrow, apical area fissus; the outer edges and apices concave. Cerci with base stout, narrowing, middle area curved inwards, U-shaped, apices rounded, invisible in dorsal view. Subgenital plate with basal area broad, near middle area narrow, and curved upwards, with a shallow longitudinal furrow, apex arc-shaped concave. Styli cylindrical, apices rounded on ventral surface of subapical area.

Coloration. Body light brown. Frons, inner margin of first segment of antenna and ventral margin of fastigium verticis black. Eyes light yellowish brown. Apices of femora and bases of tibiae dark brown, apices of spines on ventral surface of femora and tibiae black.

Female. The appearance and coloration are similar to male. Pronotum shorter, anterior margin slightly protruding forward, posterior margin concave. Tegmina and hind wings absent. Tenth abdominal tergite short, centre of posterior margin fissurate. Cerci conical, apices acute, covered by thin hairs. Ovipositor short, moderately curved upwards, dorsal and ventral margins smooth, dorsal valvulae slightly longer than ventral ones, apices rounded. Subgenital plate with basal area broad, apical area narrow, posterior margin concave, the lateral lobes acutangular, apices acute.

Type material. Holotype: male, Yinggezui, Baisha, Hainan, 22 May 2014, collected by Jiao Jiao. Paratypes: 1 male and 2 females, other data as holotype; 1 female, Yinggezui, Baisha, Hainan, 23 May 2014, collected by Jiao Jiao.

Measurements(mm). Body: ♂23.0–25.6, ♀22.0–24.0; pronotum: ♂7.1–7.3, ♀6.4–7.0; postfemora: ♂9.5–9.7, ♀9.7–19.6; ovipositor: 10.3–10.6.

Discussion. The new species is allied to Anelytra curvata Ingrisch, 1998 , but it differs from the latter in: male cerci obviously curved inwards, U-shaped; apical and outer edges of tenth abdominal tergite concave; apical area of subgenital plate curved upwards, posterior margin arc-shaped.

Etymology. The name of the new species is derived from the type locality, Hainan. Distribution. China (Hainan).
