Type material.

Holotype at MHNP, pinned, labeled: handwritten "Lectotype Ardistomis cordicollis Putz. By Erwin 1976"/ "Lectotype Clivina labialis Chd. Des. S.W. Nichols 1984"/ printed in red paper “lectotype” / handwritten in box "cordicollis Putzeys. Nlle Grenade C. Reiche".

Type area.

Given by Putzeys (1866: 646) as "Nouvelle Grenade" = Colombia.

Diagnosis.

Elytral surface smooth, striae complete, impunctate, 4 setiferous punctures in interval 3, humeri square, sides subparallel. Pronotum notably cordiform. Size given by Putzeys as 4.5 mm.

Habitus.

Fig. 37 .

Note.

The unique type seen appears to be a member of the puncticollis group. I have been unable to examine the genitalia, but the general structure is similar to the species of this group (I observed 4 setiferous punctures in interval 3 contrary to Putzeys’ original description which mentions 3 punctures). The species appears to be most similar to Semiardistomis exspectatus sp. n.

Geographical distribution

( Fig. 57 ). This species is known only from an unspecified location in Colombia.
