Measurements, in mm. males. n= 1. Total length, 28.1; prothorax length, 7.1; greatest prothorax width, 9.9; elytral length, 18.2; humeral width, 9.8.

Type material. We examined the male holotype ( Figs 66–67 ), from “La Garita”, Colombia ( USNM) .

Discussion. This species is known only from the holotype specimen. Tippmann (1953) mentioned that the specimen has rounded lower ocular lobe; however, examination of the type-specimen did not support this statement, since it possessed subtriangular lower ocular lobe, as in the other species of the genus. For more comments see A. homoplatus and A. cruentatus .

Geographical distribution. The species was described from “La Garita”, Colombia. According to the “ Diccionario Geográfico de Colombia ” (IGAC, 1996) there are four toponymyns for this locality, making it difficult to obtain the precise type-locality. The toponymyns are: “1. Caserío en el municipio de Tibú, departamento de Norte de Santander, al sureste de la cabecera municipal; 2. inspección de policía en el municipio de Los Patios, Departamento de Norte de Santander al suroeste de la cabecera municipal; 3. Loma en el municipio de Tubará, Departamento del Atlántico, al norte de la cabecera municipal, tiene una altura aproximada de 100 m sobre el nivel del mar; 4. Punta de la costa del mar Caribe en el municipio de Santa Catalina, Departamento de Bolivar, al noreste de la cabecera municipal ”.

Specimens examined. COLOMBIA, “ La Garita ”, male (holotype), 1912, Fritsche leg. ( USNM) .

Measurements (mm). female/male. n= 11/8. Total length, 16.60±2.51/17.60±2.86; prothorax length, 3.75±0.55/4.18±0.79; greatest prothorax width, 5.17±0.90/5.56±1.07; elytral length, 11.09±1.85/11.56±2.04; humeral width, 5.56±1.00/5.70±1.02.

Type material. We examined the male lectotype ( Fig. 89 ), from Brazil ( MNHN) , and a photograph of the male holotype of A. hassenteufeli ( Fig. 90 ), from Paraguay .

Discussion. Andraegoidus homoplatus is similar to A. cruentatus and A. laticollis . It differs from A. cruentatus in having longer antennae, exceeding elytral apex in males, maximum at segment VIII and in females, exceeding the elytral apex, and differs from A. laticollis in having the prothorax not strongly swollen and at least a pair of visible lateral tubercles. Hüdepohl (1985) recognized A. hassenteufeli as a subspecies of A. homoplatus and characterized it by possessing elytra with stronger and denser punctures. Botero & Monné (2011) found no significant variability to differentiate these populations and proposed their synonymy. For additional comments see A. cruentatus .

Geographical distribution. This species occurs in Brazil (GO, DF, MG, Paraíba to Minas Gerais) ( Hüdepohl, 1985), Paraguay (CA, IT), Argentina (MI, TU) , and Uruguay (CL). A new state record from Paraná ( Brazil) is added ( Fig. 228 ).
