Diagnosis.
Description from Hou et al. (2013: 286-287) "Body slender and elongate, length (from apex of vertex to tip of tegmina): male 3.7-4.8 mm, female 4.3-5.1 mm, often with blackish brown markings. Head with eyes narrower than pronotum. Vertex longer or slightly shorter in middle than broad at base (0.95-1.24: 1), apex projected in front of eyes. Submedian carinae uniting before apex, greatest length of basal compartment shorter than wide at base of vertex (0.48-0.81: 1). Frons relatively long, longer in middle line than wide at widest part (~ 2.73-3.00: 1), widest at middle or apex. Rostrum reaching mesothoracic trochanters. Antennae cylindrical, very long, surpassing apex of clypeus, basal segment longer in middle than wide at apex (3.67-5.22: 1), shorter than frons in middle line (0.49-0.74: 1), shorter than the second segment (0.40-0.56: 1). Pronotum shorter than vertex in middle line (0.58-0.96: 1), lateral carinae attaining hind margin. Mesonotum longer in middle line than vertex and pronotum together (1.33-2.05: 1). Tegmina elongate, longer in middle line than wide at widest part (1.76-3.16: 1), much longer than abdomen, hyaline, cross vein deposited medially, apical margin acutely rounded. Spinal formula of hind tibia 5-6-4. Post-tibial spur large and thick, concave on inner surface, without teeth along the hind margin, with an apical tooth. Anal segment of male short, ring-like, left lateroapical angle produced into process. Pygofer with two broad lamellate medioventral processes, between of them with a V-like emargination. Genital styles broad in basal half, forked or with process at apex. Aedeagus with or without phallobase, phallus tubular, curved C-like and directed segmental venter."
