Characteps : A genus of minute, inconspicuous insects recognized at once by their very small 

 size and by the tuberculate pronotum. Head subquadrate, almost as broad as high, a little deflexed; 

 base arcuate, sinuate and feeblj' bituberculate; eyes very large and ovate, much wider than high ; ocelli 

 small, inconspicuous, farther from each other than from the eyes and situated about on a line drawn 

 through centers of eyes; inferior margins of genae sloping and sinuate; clypeus broad, extending for half 

 its length below inferior margins of genae, tip rounded or truncate. Pronotum convex, entirely covered 

 with small nodules or tubercles, without suprahumerals but with a short, heavy posterior process; 

 metopidium sloping, broader than high, extended over the head in two tubercles; median carina strongly 

 percurrent and nodulate; humeral angles large, heavy, subconical and blunt; no suprahumeral horns; 

 posterior process short, heavy, usually depressed in the middle and swollen at the tip, impinging on the 

 tegmina; sides of mesonotum very narrowly exposed as points on each side; no true scutellum. Tegmina 

 broad, subhyaline, often mottled; base broadly coriaceous and punctate ; veins indistinct; five apical 

 and two discoidal cells; tip rounded; no apical limbus. Legs short and heavy; hind tarsi longest. 



Type minutus Fabricius. 



Geographical distribution : This genus has been found in India, Ceylon and parts of the
