Prehumerus. Development: obsolete, Shape: arcuate, Extent: to 1/2 of pronotal length, Anterior end: distant from lateral pronotal carina, Posterior end: distant from posterior pronotal angle or margin, Arc: weak. Lateral carinae. Convergence: moderate, Junction: present, Narrowest point: at posterior 1/5–1/4 of marginal carina. Scutellum. Size: robust. ELYTRA. Humeral carina: absent. Apices. Arrangement: conjoint, Shape: arcuate. Pubescence. Extent: entire ornamental. STERNUM. Prosternal lobe. Distal margin: subtruncate. Prosternal process. Shape: subparallel, Sides: straight, Angles: obtuse, Angles (tips): sharp, Disc: flat.

Metasternum. Metasternal projection: flat. ABDOMEN. Basal ventrite. Modifications: absent. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: angulately sinuate. LEGS. Metatarsus. Length to metatibia: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA. Ovipositor. Shape: square (uritiform).

Variability. The species is known only from the female holotype.

Diagnosis. Agrilus cicadelloides sp. nov. is similar to A. scutellaris Deyrolle, 1864 by the small eyes, by the trapezoid pronotum, by the sculpture of the pronotal disc, by the absence of a prehumerus, and by the robust scutellum. The new species can be distinguished by having a cluster of reddish setae on head, by an obvious pronotal lobe, and by conjointly arcuate elytral apices.

Type material. Type locality: Malaysia, Sarawak, Kampung Kuap [01°24'28”N, 110°21'38”E]. Type specimens. Holotype ♀ (EJCB): “ Malaysia, Sarawak, Kampung Kuap, iii. 1914 ”.

Distribution. MALAYSIA: Sarawak.

Etymology. The specific name cicadelloides is derived from the family name Cicadellidae (Hemiptera), and the suffix- oides, denoting form or resemblance to stress similarity with a leafhopper.
