Thailus rectilinea, Cao, Yanghui & Zhang, Yalin, 2013

Cao, Yanghui & Zhang, Yalin, 2013, Two new erythroneurine leafhopper genera and first record of Thailus Mahmood from China (Hemiptera: Cicadellidae: Typhlocybinae), with description of four new species, Zootaxa 3686 (3), pp. 363-372 : 369-370

Thailus rectilinea sp. nov.

( Figs 1 j–m, 4)

Description. Natural coloration and shape slightly distorted after removal from alcohol and drying. Vertex, anterior margin of pronotum and mesonotum ( Fig. 1 l) sordid orange, hind part of pronotum dark, face ( Fig. 1 m) light brownish-yellow, upper part of midline sordid orange, anteclypeus pale. Forewing ( Figs 1 j, k) transparent, veins brown.

Male 2S abdominal apodemes ( Fig. 4 a) extended to midlength of fourth sternite. Anal tube appendage ( Fig. 4 c) hooked, curved ventrad.

Pygofer side ( Fig. 4 b) with numerous fine setae; pygofer dorsal appendage triangular, ventral appendage long and bent. Subgenital plate ( Fig. 4 f) with about 3 macrosetae at subapical angle, compressed apical part relatively long. Style ( Fig. 4 g) straight apically, preapical lobe relatively large. Connective ( Fig. 4 h) narrow, distinctly keeled along midline. Aedeagal shaft ( Figs 4 i, j) almost straight, preatrium sinuated in side view.

Measurement. Male length 3.3mm.

Material examined. Holotype: 3, THAILAND, Phetchabun, Nam Nao NP Pine forest/Sambon 1, 16°42.47'N, 101°35.26‘E, 872m, Malaise trap, 16–23. x. 2006, coll. Noopean Hongyothi. Paratype: 3, THAILAND, Loei, Phu Ruea NP Suan Hin Pali, 17°29.86'N, 101°20.55'E, 1178m, Malaise trap, 5–12. iv. 2007, coll. Patikhom Tumtip.

Deposition. Holotype is housed in the Queen Sirikit Botanical Garden, Chiang Mai, Thailand; paratype in Illinois Natural History Survey, Champaign, USA.

Diagnosis. Color pattern and body size similar to T. versicolor sp. nov., but genital capsule and proportion of aedeagus much larger, anal tube appendage hooked, style straight apically, aedeagal shaft straight.

Etymology. This new specific epithet is derived from the Latin word “ rectilineus ” in view of the straight apical part of style.
