New species and new record in Lamiinae from Espírito Santo (Brazil) (Coleoptera: Cerambycidae)

Four new species are described from Brazil (Espírito Santo): Xylergates quinquetuberculatus (Acanthocinini); Trichonius w‐notatus (Acanthocinini); Pseudobeta casariae (Onciderini); Xenofrea mariae (Xenofreini). Additionally, Nyssodrysina infima (Bates, 1885) is recorded for the Brazilian state of Espírito Santo for the first time. Key-Words. Longhorned beetles; Neotropical region; South America; Taxonomy.


INTRODUCTION
The Brazilian state of Espírito Santo has a territorial area of 45,597 km², which corresponds to 0.53% of the national territory, making it one of the smallest Brazilian states. It is located on the Atlantic coast between the parallels 17°53′29″S and 21°18′03″S and the meridians 39°41′18″W and 41°52′45″W (Lederman & Padovan, 2005). Despite its size, this state still has a significant part of its territory covered by the Atlantic Forest (about 12.6% -see Fundação SOS Mata Atlântica, 2019), which is one of the most diverse and threatened biomes on the planet (Ribeiro et al., 2011).
This work deals with the subfamily Lamiinae, the most diverse in the family Cerambycidae.
The species was registered by Ødegaard (2004) in Brosimum utile (Kunth) Oken (Moraceae). This species of tree is present in Central America and widely distributed in Amazonian regions of South America. Most likely, the current records of N. infima underestimate its actual distribution, which must be similar to that of its host plant. The presence of N. infima in the state of Espírito Santo, raises the question if the species uses other trees of the genus Brosimum as host plant or was introduced in the region. According to Machado & Pederneiras (2007), there are six species of trees of this genus occurring in state of Espírito Santo.

Dillon & Dillon, 1945) is questionable. Dillon & Dillon (1945) separated Beta from Midamus in the alternative of couplet "29": "Head with front transverse, " leading to Beta; "Head with front subquadrate or elongate, " leading to Midamus. However, the difference between transverse and subquadrate may be nonexistent. In addition, according to Zajciw (1972) the frons is subquadrate in Pseudobeta (the type species of Beta and Pseudobeta are synonyms). In fact, Dillon & Dillon (1945) compared Beta with Midamus: "Somewhat related to Midamus in the broad front, small eyes, short genae and cylindrical pronotum; distinct in having the eyes broader, more oblong; antennal tubercles more prominent; pronotum transverse, sides not excavated, distinctly tuberculate, disk with two tubercles; elytra more tapering, apices acute, base punctate, humeri more elevated; metatibiae subequal in length to metafemora. " These differences are at least partially incorrect. For example, the prothorax is transverse in the two species currently placed in Midamiella, and according to Dillon & Dillon (1945), in the description of Midamus, the pronotum is transverse. We believe that Pseudobeta is the best genus to include the new species, however, a comprehensive review of this genus and Midamiella is necessary.

Dimensions in mm
Pseudobeta casariae sp. nov. is similar to P. ferruginea Galileo & Martins, 1990, but differs as follows: dorsal pubescence mostly yellow and white; sides of prothorax not distinctly widened centrally; antennomere III at most as wide as posterior margin of the prothorax; frons transverse. In P. ferruginea, the dorsal pubescence is mostly orangish, sides of prothorax are distinctly widened centrally, antennomere III wider than posterior margin of the prothorax, and the frons is elongate.
