Giesberteclipta gen. nov.

Etymology. We are pleased to name this genus in memory of the late Edmund F. Giesbert for his many contributions to the study of North and Central American Cerambycidae . Feminine gender.

Type species. Ommata (Eclipta) costipennis Giesbert, 1991 .

Diagnosis. Giesberteclipta differs from Eclipta Bates, 1873 , mainly as follows: procoxal cavities open; elytral carina distinct from humerus nearly to apex; elytral sides not convergent towards apex; male parameres rounded at apex, laterally without long setae. In Eclipta [based on type species – Eclipta flavicollis (Bates, 1873) ] the procoxal cavities are closed, the elytral carina is from absent to almost absent, the elytral apex is distinctly convergent towards apex, and the male parameres are truncate at apex and laterally with long setae.

Description. Length between 5.5 and 7.5 mm.

Male ( Figs 4–7 )—Head not elongated behind eyes (posterior edge of eyes near the anterior edge of prothorax); rostrum (between the apex of inferior ocular lobe and genal apex) short (less than 0.5 times length of one inferior lobe in frontal view). Eyes large, distinctly emarginate. Margins of inferior ocular lobes not near each other (distance between them about 0.4 times length of one inferior lobe in frontal view). Antennae reach or almost reach the elytral apex; antennomeres III–XI filiform, slightly enlarged after VII (antennal club nearly absent).

Prothorax subcylindrical, elongate, moderately swollen at middle region, without tubercles on this area. Pronotum densely pubescent with long, sparse setae; gibbosities from feeble to moderate (median gibbosity usually more distinct). Procoxal cavities open. Prosternal process strongly narrowed centrally; apex truncate. Mesosternal process obliquely, moderately elevated at base. Mesepisterna not visible in dorsal view near humerus. Metasternum tumid, with the central region distinctly more elevated than metacoxae. Metepisterna subtriangular (base distinctly wider than apex).

Scutellum densely pubescent. Elytra long, covering or almost covering entire abdomen, narrower at middle, not convergent from base to apex; apex obliquely subtruncate (sometimes almost rounded); elytral suture not dehiscent; elytral carina strongly marked from humerus nearly to apex; lateral area between elytral carina and epipleuron sub-vertical, mainly at basal two-thirds.

Pro- and mesocoxae without spicule. Femora clavate; metafemoral peduncle distinctly long. Metatibiae without brush of setae. Metatarsomere I slender, about as long as II–III together.

Abdomen slightly shorter than thorax, not strongly curved downward; ventrite V not elevated laterally. Parameres proportionally short, but elongate; lateral margins without long setae; apex rounded with long setae.

Female—Distance between inferior ocular lobes wider than in males (about 0.7 times length of one inferior lobe in frontal view); antennae reach about distal fifth of elytra; abdomen about as long as thorax..

Included species: Giesberteclipta costipennis (Giesbert, 1991) , comb. nov.; G. monteverdensis (Giesbert, 1991) , comb. nov.
