  Type species:

   Smicrotatodelphax perkinsi Kirkaldy, 1906 by monotypy.

Introduction

This was an endemic monotypic genus until Muir (1917) added a second species from Java. Muir (1917) made the comment that these two species were the smallest delphacids he knew, reaching a total body length of only 1.3 mm and Kirkaldy (1906) noted that S. perkinsi was the smallest planthopper known to him.

Head, especially the eyes, very large, the latter extending laterally as far as the base of the tegmina, and posteriorly nearly touching the base of the pronotum. Vertex with lateral keels forking at about one-third of the length of the head (dorsally), meeting acutely on the top of the head continuing to apex of frons as a single keel. Antennae reaching beyond base of clypeus. Pronotum tricarinate, the lateral keels straight, diverging posteriorly, but practically reaching the posterior margin of pronotum. Scutellum transverse, with 3 somewhat obscure keels. Tegmina not nearly reaching apical margin of abdomen, rounded apically. Tibial spur with about 13 teeth. (Kirkaldy 1906)
