Tropidozineus wappesi Monné & Monné, 2012
Lamiinae: Acanthocinini
This is a small (7–8 mm), robust species with the surface of the elytra and pronotum closely punctate throughout and with its brown integument obscured by dense, multicolored pubescence. The pronotum is decorated with two black stripes along the midline that parallel each other. The pubescent color pattern of the elytra is extremely variable between individual specimens and defies any attempt at a meaningful summary description. The species is most often taken by beating small branches on partially burnt or cut trees but also readily comes to lights. It is known only from Bolivia and Brazil. In Bolivia it has been collected at the Potrerillo del Guenda Reserve, Bermejo, and the Flora and Fauna Hotel near Buena Vista in Santa Cruz Department.

Although this robust species has similar size (16–18 mm) and an elytral apex covered in pale pubescence like its congener T. andícola, the apices are unarmed and truncate versus strongly spined, as in that species. In addition to its elytral punctation, this species also has rows of rather evenly spaced, black, tuberculate setal tufts on the central portion of the disk. Its pronotum is attractively marked with a light brown, central midline bordered by bright white pubescence, which in turn is sharply margined by short, coal-black pubescence. Known only from Bolivia and Colombia, this species has been collected in Villa Tunari and Cochabamba (Cochabamba Department) and Achira (Santa Cruz Department) in Bolivia.
Urgleptes ovalis (Bates, 1866)
Lamiinae: Acanthocinini
Most species in the large genus Urgleptes (almost 80 species) are small (4–6 mm) and drab, with many difficult to characterize.

It is easily recognized by the somewhat skull-like pattern of white pubescence on the pronotum. White or pale yellow pubescence also forms maculae on the head, middle, and apex of the elytra. These white maculae are interrupted by round, black spots. The legs and antennae are black. It occurs throughout South America and Panama, where specimens are usually collected at lights. In Bolivia it has been recorded from the Riberalta area (Beni and Pando Departments) and the vicinity of the Flora and Fauna Hotel near Buena Vista, the Potrerillo del Guenda Reserve, and Refugio Los Volcanes in Santa Cruz Department.
Octotapnia ceiaca Galileo & Martins, 1998
Lamiinae: Acanthoderini
The shape and pubescence of this unique little (4–7 mm) acanthoderine is somewhat similar to Myoxinus pictus, but its unusual antennal formula of only 8 antennomeres (typically 11 in Cerambycidae) immediately sets it apart. The basal four segments are rather typical of most Cerambycidae, but the remaining four are very reduced in length. This species is rarely found but can be attracted to lights where it is easily overlooked. It is known only from Brazil and Bolivia, where it has been collected from the vicinity of the Flora and Fauna Hotel near Buena Vista in Santa Cruz Department.

This dark brown, medium-sized (10–16 mm) species is heavily punctate on its dorsal surface and densely covered in primarily golden-brown pubescence. Its most noteworthy markings are the two small, white pubescent maculae near the center of each elytron that give it its name. It was, until recently, in the genus Psapharochrus. It has very pronounced protarsi, which are black and densely pubescent. The antennae and femora are speckled with very small patches of white setae. This species is known from Colombia, Peru, French Guiana, and Bolivia. In Bolivia it is known from the vicinity of the Flora and Fauna Hotel near Buena Vista, the Potrerillo del Guenda Reserve, and Refugio Los Volcanes in Santa Cruz Department.
Psapharochrus corticarius (Tippmann, 1960)
Lamiinae: Acanthoderini
This 10–14 mm long species has a white M-shaped pubescent macula on the pronotal disk. Otherwise, it is coated by a mottled golden-orange pubescence, although not too dense such that the black integument often is exposed. The elytra have a pronounced spine at the apices. This species has been collected in Brazil and Bolivia. Bolivia localities include Beni Department, the Chaparé region of Cochabamba Department, and the vicinity of the Flora and Fauna Hotel near Buena Vista, the Potrerillo del Guenda Reserve, and Refugio Los Volcanes in Santa Cruz Department.
Psapharochrus homonymus (Blackwelder, 1946)
Lamiinae: Acanthoderini
This 11–14 mm long species is one of the most boldly patterned lamiines. It has dense white pubescence throughout, but this is broken up by large, reticulating, black maculae. The antennae are black except for a white scape and white annulate bases of most segments. It is distributed in Brazil, Peru, and Bolivia, where it has been collected at the Vicoquin area above Achira at 2,000 m in Santa Cruz Department. It is also recorded from Cochabamba Department.
Psapharochrus laetificus (Bates, 1880)
Lamiinae: Acanthoderini
This large (15–19 mm), black, shining species has distinct carinae running the length of the elytra on each side of the suture. The elytra and pronotum each have six to seven large ochraceous maculae, most spaced on the outer halves, each narrowly bordered by white setae. The pronotal disk has a pronounced middle ridge flanked by two less elevated ridges. This species is rarely encountered but occasional at lights. It is known from Ecuador, Peru, Brazil, and Bolivia, where it has been collected from the vicinity of the Flora and Fauna Hotel near Buena Vista in Santa Cruz Department.
Psapharochrus maculatissimus (Bates, 1861)
Lamiinae: Acanthoderini
This moderate-sized species (9–12 mm) is very distinct among the large genus Psapharochrus by the dense, mottled pubescence of three colors: tan, dark brown, and white. The mottling is so complete that no large maculae of one color are present. The third and fourth antennomeres have white pubescence at the base, middle, and apex but otherwise are brown. The remaining antennomeres are white at the basal half and brown at the apex. This species is known only from Brazil and Bolivia. In Bolivia it has been collected, mostly at lights, from Villa Tunari in Cochabamba Department and from the Flora and Fauna Hotel near Buena Vista, Potrerillo del Guenda, and Refugio Los Volcanes in Santa Cruz Department.
Punctozotroctes bolivianus Martins & Galileo, 2007
Lamiinae: Acanthoderini
This small (9–11 mm), dark brown species has, as the genus name implies, the dorsum covered in nearly confluent punctures. Even the central ridge and lateral tubercles of the pronotum are punctate. In addition to the punctures the elytra have sparse, short, recumbent, gold and pale white pubescence on its surface. This species is a Bolivian endemic known from the vicinity of the Flora and Fauna Hotel near Buena Vista and the Potrerillo del Guenda Reserve in Santa Cruz Department in Bolivia.
Pyrianoreina piranga Martins & Galileo, 2008
Lamiinae: Acanthoderini
This small (6–8 mm), reddish-brown acanthoderine is unusual in that the legs and antennae (at least the basal segments) are coated with long ochraceous setae. The pronotum and elytra have shorter, more appressed setae of similar color. The pronotum in the species is very short, more than twice as wide as long. The elytral suture is very dark and mostly lacking setae. This species is known only from Ecuador and Bolivia, where it has been collected in Santa Cruz Department at the Flora and Fauna Hotel and Buena Vista.
Steirastoma breve (Sulzer, 1776)
Lamiinae: Acanthoderini
This is a large (15–23 mm), rugged-looking, common species with a shining piceous integument and a distinct white pubescent pattern interrupted by small, dark, shining tubercles at the elytral base and circular, glabrous black spots on the dorsum. Like other species in the genus, each elytron has a longitudinal, glabrous carina. Both sexes have wide front tarsal segments fringed in long, silky, black hairs. It is the most widespread species in the genus and one of the most widespread of all neotropical lamiines, having been recorded from throughout Central and South America and the West Indies. It is widespread in Bolivia, having been collected in the Riberalta area (Beni and Pando Departments), Cristal Mayu (Cochabamba Department), and Potrerillo del Guenda, Refugio Los Volcanes, the Flora and Fauna Hotel near Buena Vista, and Camiri (Santa Cruz Department). It has also been recorded from La Paz Department.
Steirastoma stellio Pascoe, 1866
Lamiinae: Acanthoderini
This is one of the smallest (13–16 mm), but still robust, Steirastoma species. It has three glabrous carinae on the pronotum and one on each elytron. The pronotum has two acute tubercles on each side. The head is quite broad, as is the case with many species of the genus. It is very widespread in Central and South America, being known from Honduras, Costa Rica, Colombia, French Guiana, Brazil, Paraguay, Argentina, Uruguay, and Bolivia. It has also been introduced into Africa. In Bolivia it is known from the Flora and Fauna Hotel near Buena Vista, the Potrerillo del Guenda Reserve, and near Camiri in Santa Cruz Department.
