The type material treated in the present paper is deposited in the Insect Collection of the Shanghai Normal University
Dissected parts were preserved in Euparal mounting medium on a plastic slide that was placed on the same pin with the specimen. To investigate the foveal pattern, a male paratype was completely disarticulated and preserved on a slide preparation. Habitus images were taken using a Canon 5D Mark III camera in conjunction with a Canon MP-E 65mm f/2.8 1-5X Macro Lens and a Canon MT-24EX Macro Twin Lite Flash. Images of the morphological details were made using a Canon G9 camera mounted on an Olympus CX31 microscope. Line drawings were initially produced using an Olympus U-DA Drawing Tube, and then inked in Adobe Illustrator CS5. Zerene Stacker version 1.04 was used for image stacking. All images were modified and grouped in Adobe Photoshop CS5 Extended.
The collecting data of the material are quoted verbatim, information not included on the label is placed in parentheses. A slash is used to separate different labels.
The following abbreviations are applied: – length of the dorsally visible part of the abdomen (posterior to elytra) along the midline – maximum width of the abdomen – length of the elytra along the suture – maximum width of the elytra – length of the head from the anterior clypeal margin to the occipital constriction – width of the head across the eyes – length of the pronotum along the midline – maximum width of the pronotum Length of the body
Body large-sized, 1.85–2.23 mm; frons with a Y-shaped carina extending anteriorly to reach clypeal anterior margin; each eye of macropterous male with about 55 facets, that of apterous male with about 25–30 facets, and apterous female about 12 facets; antennomeres III elongate, IV–X distinctly transverse; abdominal tergite IV with three pairs of marginal carinae, discal carinae parallel; sternite IV with long median and two shorter admesal carinae.
