Genus: Symplanella
Name
Symplanella recurvata Yang & Chen, 2014 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Measurements
Body length including forewing: male 5.78–5.98 mm (N = 6), female 6.15–6.25 mm (N = 12); forewing length: male 4.90–5.15 mm (N = 6), female 5.30–5.40 mm (N = 12).
Coloration
General color light yellowish brown with somewhat green. Ocelli reddish brown, eyes black brown. Antennae with one black spot at apex of second segment. 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 narrower than pronotum (0.86:1). Vertex shorter in middle line than broad at base (0.60:1). Frons 1.28 times longer in middle line than widest part. Pronotum slightly longer in middle line than vertex (1.21:1). Mesonotum 1.24 times as long as vertex and pronotum together in middle line. Forewing longer in middle line than broad at widest part (4.71:1). Hindwing longer in middle line than broad at widest part (2.01:1), venation as shown in Fig. 7.
Abdomen
Anal segment of male in posterior view (Fig. 8) nearly long oval, in lateral view (Fig. 9) with basal half parallel dorsally and ventrally, apical margin produced into stout process ventrally, which curves cephalad, apex acutely rounded. Pygofer in lateral view (Fig. 9) with dorsal margin distinctly shorter than ventral margin, posterior margin mostly straight, concave at dorso-posterior angle. Genital style in lateral view slender, dorsal and ventral angles acutely rounded, posterior margin slightly convex; in posterior view (Fig. 10) with dorsal and ventral apex acute and rounded, inner and outer margin sinuate. Aedeagus in dorsal view (Fig. 11) with shaft straight, simple, apex rounded; in lateral view (Fig. 12) curved at basal third, apical part straight, phallobase small, lobe-like. Connective in lateral view (Fig. 12) straight, fused with base of aedeagus forming V-shape; connective in dorsal view (Fig. 11) with both lateral margins swelled laterad.
Type material
Holotype: ♂, China: Guangdong, Guangzhou, Huanan Botanical Garden (23°08'N, 113°14'E), on bamboo (Neosinocalamus sp.), 22 Nov. 2006, X.-S. Chen; paratypes: 5 ♂♂, 11 ♀♀, data same as holotype; 1 ♀, Guangxi, Daxin, Encheng, 4 May 2009, H.-R. Li.
Host plant
Bamboo (Neosinocalamus sp.).
Distribution
South China (Guangdong and Guangxi) (Fig. 37).
Remarks
This new species is closely related to Symplanella unipuncta Zhang & Wang, 2009 but differs in: i) anal segment in lateral view with one stout process at apical margin ventrally, which curves cephalad apically (with one tooth-like process at middle of ventral margin in Symplanella unipuncta); ii) posterior margin of pygofer without process (with one process in Symplanella unipuncta); iii) aedeagus without process at base (with two long stout processes basally and ventrally, which as long as aedeagal shaft).
Etymology
The new species is named after the strongly recurved tip of the anal tube.
