Disarticulated and dissected parts were preserved in Euparal on plastic slides that were placed on the same pin with the specimen. The habitus image was taken using a Canon 7D 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. 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.
The following abbreviations are applied: —length of the abdomen 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 eyes —length of the pronotum along the midline —maximal width of the pronotum
Head with large nude vertexal foveae and small frontal fovea; antennal club loosely formed by two apical antennomeres; median gular ridge prominent and broad. Pronotum globular, with setose median and lateral antebasal foveae, lacking transverse antebasal sulcus connecting these foveae. Each elytron with two large basal foveae, lacking discal stria. Tergite IV (first visible tergite) with two basolateral foveae in transverse basal sulcus; sternite IV (second visible sternite) with deep basolateral sulci.
Length 2.72 mm. Head with large, nude vertexal foveae (Fig.
