Polytuberotum Pineda & Cid-Arcos, 2017

Translated and adapted from Pineda & Cid-Arcos (2017) (Spanish to English)

Redescription. Frons transverse; antennal tubercles prominent, moderately spaced; median groove barely visible throughout. Genae elongate. Eyes finely faceted, lower lobes strongly separated, distance between them at least twice length of one lower lobe. Mandibles poorly developed, coarsely punctate. Antennae thick, extending beyond elytral apex; scape clavate; antennomere III the longest.

Prothorax subsquare, slightly wider than long, with conical lateral tubercle with blunt apex. Pronotum with moderately raised, irregular protuberances varying in number (five in P. metachroma , four in P. boteroi ). Scutellum transverse, widely rounded apically. Elytra fused, slightly widening from base to about medial third, then gradually narrowing toward apex; with hook-shaped tubercle with blunt apex, slightly directed backward. Elytral apices narrow, individually rounded. Legs robust and long; metafemora 0.5 times elytral length; mesotibiae with oblique groove on external middle area. Metaventrite short, with an inverted V-shaped sulcus between metacoxae.

Remarks. Polytuberotum resembles Tuberolamia due to the presence of elytral tubercles. However, it differs by the transverse frons (elongate in Tuberolamia ), prominent antennal tubercles (slightly elevated in Tuberolamia ), pronotum with distinct conical lateral tubercles (absent in Tuberolamia ), pronotum with protuberances (absent in Tuberolamia ), elytral tubercle located near humeri (far from humeri in Tuberolamia ), and smooth elytra (veined in Tuberolamia ).
