RESUMO
Phoebella Lane, 1966 is a Neotropical genus of flat-faced longhorned beetles (Cerambycidae, Lamiinae, Hemilophini) with three species. Here, a new species, Phoebella queirozae sp. nov., is described from the state of Ceará (Brazil). The male terminalia of Phoebella phoebe (Lepeletier and Audinet-Serville, 1825) is described for the first time. The external morphology and male terminalia of the new species and P. phoebe are compared, and the value of male terminalia characters in the taxonomy of longhorned beetles is briefly discussed.

A key for identification of the 34 genera of Acanthocinini with erect setae on the elytra occurring in Mexico and Central America (excluding the Caribbean Islands) is provided. Leptrichillus Gilmour, 1960 is synonymized with Lepturgotrichona Gilmour, 1957, and Leptrichillus minutus Gilmour, 1960 is synonymized with Lepturges stigmaticus Bates, 1881 (currently, Lepturgotrichona stigmatica).

Cerambycidae is one of the largest families of beetles, containing about 38,000 described species (Tavakilian Chevillotte 2018). In most species of this family, adults possess a stridulatory device that allows them to produce squeaking sounds (Wang 2017). In the subfamilies Prioninae and Parandrinae, individuals stridulate by rubbing their ridged hind femora against elytral margins (Svácha Lawrence 2014). In the other subfamilies, including Lamiinae, the stridulation is produced by friction between the ventral face of the posterior pronotal margin (plectrum) and a striated plate on the mesoscutum (pars stridens) (Svácha Lawrence 2014). Although some adults produce sounds during courtship and copulation, this sound production occurs mainly when individuals are disturbed, being considered a defensive mechanism that might act as a startle response against predators (Dumortier 1963; Svácha Lawrence 2014; Wang 2017).

Marinoni Martins (1978) proposed Anasillus for a single species, A. crinitus Marinoni Martins, 1978, based on a single male specimen from Peru, and until now, the female remained unknown. Herein, the female of this species is described and illustrated for the first time, and its geographical distribution is expanded to Colombia. Additionally, the geographical distribution of seven species of Cerambycidae is expanded to Colombia: Coleoxestia vittata (Thomson, 1861); Sphallenopsis pilosovittata (Bates, 1872); Aneflus (Protaneflus) minutivestis Chemsak Linsley, 1963; Mallocera amazonica Bates, 1870; Compsibidion charile (Bates, 1870); Alcidion sulphurifer (White, 1855); and Acanthoderes (Acanthoderes) ariasi Chemsak Hovore, 2002.

The genus Antodice Thomson, 1864 was revised by Martins Galileo (1998) and currently includes 27 species (Tavakilian Chevillotte 2017), distributed from Mexico to southern South America. Based on a single female specimen collected in Arroyo Cristal, Ka'azapá, Paraguay, the species Antodice quadrimaculata was first described by Martins Galileo in 2003. The holotype specimen was collected on 20 November 1999 by J. Jensen and is deposited in the Museum of Zoology of the University of São Paulo, Brazil. With the help of Carlos Aguilar, from Paraguay's National Museum of Natural History, we were able to determine the exact location where the holotype was collected. With the collection and the description of the male, presented herein, we describe the male of this species record its occurrence in Brazil, a new country record.We identified this species as belonging to the group of Antodice species with yellowish flagellomeres and a black apex, resembling Antodice venustula Lane, 1973 in its elytral color pattern. In A. venustula, the elytra are covered with whitish pubescence and exhibit only two patches of compact white pubescence. In A. quadrimaculata, according to Martins Galileo (2003), the elytra are of a reddish color with whitish pubescence on the dorsal anterior area and close to the apexes, and they also have three patches of compact white pubescence. The specimens of A. quadrimaculata cited herein were collected in the Iguaçu National Park (Parque Nacional do Iguaçu-PNI), the largest fragment of Atlantic forest in southern Brazil, located in the western region of the state of Paraná. The insects were collected using light traps, set up on nights with a new moon. The artificial light source was a 500-Watt incandescent lamp powered by a Honda EP 2500 generator. Sampling began at 6 p.m., ending between midnight and 3 a.m. the next day. The studied material was deposited in the entomological collection of the Museum of Zoology at the State University of Londrina (Universidade Estadual de Londrina), Londrina, Brazil (MZUEL). To better represent the expansion of the geographical distribution of the species from the holotype recorded in Paraguay (Fig. 5, 6), the cartographic material (Fig. 1) was produced using ArcGIS Software 9.0®. The map database was obtained from the Institute of Land, Cartography and Geosciences, (Instituto de Terras, Cartografia e Geologia do Paraná), Curitiba, Brazil (ITCG).
