Allorhopaliella gen. nov.

Type species: Allorhopaliella boliviana sp. nov.

Etymology. Allo- (Greek) = different, (i.e.) different from Rhopaliella . Feminine gender.

Female description. General form elongate, size small. Frons transverse. Eyes finely faceted, emarginate; lower eye lobes large, prominent; upper eye lobes well-separated, about 1/4 as wide as lower lobes. Antennal tubercles moderately prominent. Genae shorter than lower eye lobes. Last segment of palpi fusiform. Antennae 11—segmented, filiform, longer than body; scape sub-cylindrical, shorter than antennomere III; antennomere III distinctly longer than IV. Prothorax slightly wider than long, anteriorly and posteriorly with about same width; laterally with distinct, blunt tubercles about middle. Pronotum with four well-marked gibbosities. Prosternal process narrow between procoxae, expanded towards apex. Procoxal cavities open behind. Mesosternal process moderately prominent, oblique in front, distinctly narrower than mesocoxa, deeply emarginate at apex. Metepisternum narrow, subparallel-sided. Scutellum small, sub-rectangular. Elytra about 3 times as long as width across humeri, subparallel; apex sub-truncate, without spine; disc not strongly carinate; epipleura vertical. Hind legs about 1.4 times longer than forelegs; femora distinctly clavate; lateral sides of femora not carinate; metafemora distinctly not reaching elytral apex; metatarsomere I slightly longer than II–III together.

Remarks. Allorhopaliella gen. nov. shares the short metafemora with Rhopaliella Monné, 2006 , but differs as follows: antennae longer than body; distal antennomeres filiform; prosternum sparsely pubescent throughout; mesosternal process narrower than mesocoxa; elytral apex without spine at sutural angle; peduncle of metafemora without lateral carina. In Rhopaliella ( Fig. 4 ) the antennae are shorter than the body, the distal antennomeres are serrate, prosternum densely pubescent on basal two-thirds, the mesosternal process is wider than mesocoxa, and the peduncle of metafemora is laterally carinate. It differs from Dihammaphoroides Zajciw, 1967 as follows: prothorax with lateral tubercle; elytra about 3 times as long as width across humeri; distal antennomeres filiform. In Dihammaphoroides the prothorax has no lateral tubercle, the elytra are about 3.5 times as long as width across humeri, and the distal antennomeres are serrate. It differs from Dihammaphora Chevrolat, 1859 , that also has species with short metafemora, mainly by the elytral carinae not very distinct (present in Dihammaphora ), and by the prothorax with lateral tubercle (absent in Dihammaphora ). Allorhopaliella differs from Rhopalophora Audinet- Serville, 1834, mainly by the shorter metafemora (surpassing elytral apex in Rhopalophora ), and by the shorter prothorax with distinct tubercle at lateral sides (longer and without distinct tubercle in Rhopalophora —we believe that Rhopalophora baracoana Zayas, 1975 does not belong to this genus).
