Figs. 1–9 .

Type specie: Coleopterodes liliputianum (Signoret)

Solenostoma Signoret 1863: 575 ; Stål 1873: 117; Lethierry & Severin 1896: 9; Reed 1900: 178; Drake & Ruhoff 1960: 25; Drake & Ruhoff 1965:122.

Coleopterodes Philippi 1864: 306 ; Kirkaldy 1900: 241; Bergoth 1922: 152; Drake & Ruhoff 1960: 24; Drake & Ruhoff 1965:122.

Diagnosis: Small species. Head short, with two sets of tubercles; anterior pair as developed as or less developed than occipital pair; occipital pair widely separated. Eyes poorly developed, ovate. Bucculae closed in front. Antennae thick, covered with abundant hairs. Pronotum coarsely punctuated, tricarinate. Collar slightly raised. Labium reaching or slightly surpassing the prosternum. Paranota obsolete. Orifice indistinct. Mesocoxae closer to metacoxae than procoxae. Hemelytra sharply convex, not surpassing the length of the abdomen, coarsely punctuated, not divided in the usual areas. Hypocostal ridge uniseriated.

Redescription: Small species (1.57–2.17). General shape ovate ( Figs. 1–6 ). Head quadrate, armed with two pairs of tubercles; space between anterior tubercles half the space existent between occipital tubercles ( Figs. 2–7 ). Eyes dark brown, ovate, higher than wide, poorly developed with a few big ommatidous ( Fig. 3 ). Bucculae large, subrectangular in lateral view ( Fig. 3 ), closed in front ( Figs. 4–8 ). Antennae thick, covered with abundant decumbent hairs ( Figs. 2–7 ). Pronotum wider than long, tricarinate, lateral and median carinae pale, ridge like, posterior process short ( Figs. 1–6 ). Collar slightly raised, paranota obsolete ( Figs. 1–6 ). Rostral channel deep, labium reaching or slightly surpassing the prosternum ( Figs. 4–8 ). Hemelytra sharply convex, lacking the usual veins and areas, same length as abdomen, coarsely punctuated. Hemelytra punctuations bigger than those present in the pronotum ( Figs. 1–6 ).

Geographic distribution: Chile (Santiago, Malleco) , Argentina (Buenos Aires: Chacabuco, Mar chiquita, Otamendi; Neuquen: Pucara Lacar)

Host plant: Acacia cavenia ; Baccharis pingraea ; Berbera sp.

Comments: Signoret (1863) first named this genus Solenostoma and designated as type species Solenostoma liliputiana , but the generic name was preoccupied in the Chelicerata. One year later Philippi described the same genus under the name Coleopterodes and designated as type species Coleopterodes fuscescens . This is the valid generic name Coleopterodes Philippi (1864) and the type species of the genus is Coleopterodes liliputianum (Signoret) because it is a senior synonym of Coleopterodes fuscescens .
