Paratypes (10) all bearing the label [yellow, typeset and handwritten] “ LIOGENYS / CLIPEOSETOSA / PARATYPE / Cherman M. A. ”. Six female paratypes bearing the same data of the holotype (ZMHB). Three female paratypes with the label: [green, outlined, typeset] “ Hist. Coll. (Coleoptera) / Nr. 24131 / Liogenys quadridens Burm. / Columb., Moritz. / Zool. Mus. Berlin ” (ZMHB). One female paratype with the data: [white, typeset] “ VENEZUELA: Lara / 20 km. E. Carora / 24 - VI- 1976 / Holotype and nine paratypes deposited at ZMHB. One paratypes at USNM. Additional material. Three females (FSCA) were port interceptions from Gulfport, Mississippi, United States of America in Musa (Musaceae) (bananas, plantains, etc.) originating from Colombia. We examined photographs of these specimens provided by John Leavengood (United States Department of Agriculture, Tampa, Florida, United States of America). No specific locality was available within Colombia and it is likely that these specimens were attracted to lights during the packing or loading of this commodity.	en	Cherman, Mariana A., Basílio, Daniel S., Mise, Kleber M., Frisch, Johannes, Smith, Andrew B.

03D987EFAE7F934496F5FC01FBBE1E21.taxon	discussion	Remarks. Liogenys granadina Cherman, new species resembles L. quadridens in the shape of the quadridentate clypeus and of the pygidium. However, L. granadina is smaller than L. quadridens; the distance between anterior and lateral clypeal teeth is shorter; and in the pronotal corners are defined (obsolete in L. quadridens). Frey (1969) considerated specimens of L. granadina as being L. quadridens, judging by his description in the key, one of the two parameres illustration (the other one corresponds to L. quadridens), and because two paratypes (USNM and ZMHB) bear his determination label. Moreover, Frey (1969) refers to a specimen from Pernambuco, Brazil, which was found at the NHMB. This Brazilian specimen was identified as Liogenys piauiensis Cherman, 2017 by Cherman et al. (2019). There are three specimens in the USNM that were intercepted at the port of Miami, Florida on 1 May 1964 with no other information on the host or origin. This indicates that some previous port interceptions or pest reports for L. quadridens possibly included or even all of them are specimens of L. granadina.	en	Cherman, Mariana A., Basílio, Daniel S., Mise, Kleber M., Frisch, Johannes, Smith, Andrew B.

03D987EFAE7C934296F5FDC5FE261F2D.taxon	discussion	Remarks. After studying the type series of L. gebieni (ZMHB) (Fig. 5 A – C), and comparing its external features and male genitalia (Fig. 5 A – F) with that of L. macropelma type series and non-type material (Fig. 5 G), we concluded that these specimens belong to the same species. The only difference is the color, which is darker in the L. gebieni types. Nonetheless, the difference in body color is a common intraspecific variation within Liogenys. Herein, we propose L. gebieni Moser as a junior subjective synonym of L. macropelma Bates. The parameres of each L. macropelma and L. gebieni drawn by Frey (1969) seem to be different. However, there were no specimens labeled as L. gebieni among Frey’s material housed at NHMB or USNM, thus, the material used by Frey (1969) to illustrate L. gebieni parameres remains unknown. According to the United States Department of Agriculture (1971, 1974), L. macropelma has been intercepted in Florida, Texas, and Puerto Rico (United States of America) coming by aircraft from El Salvador, Panama, and South America (probably Brazil) several times in a period from 1948 – 1971, always between April and May (identification verified based on the illustration in the report). Also, it was recorded being a host of okra plant Hibiscus esculentus L. (Malvaceae) coming from Guatemala, Panama, and Venezuela, which were intercepted in Florida, California, and Puerto Rico (United States of America). Several specimens in the USNM collection had been caught in port interceptions from Houston, Texas, originated from Panama, 1966 with no other explanation. Another specimen in the USNM bears the following data: 27 April 1962 port interception from Miami, Florida originating from “ South America ”. Based on the poor state of taxonomy of the genus Liogenys when these port interceptions took place, all identifications should be considered questionable unless they can be verified using voucher specimens.	en	Cherman, Mariana A., Basílio, Daniel S., Mise, Kleber M., Frisch, Johannes, Smith, Andrew B.

03D987EFAE7A935F96F5FCC9FB2D1DCD.taxon	discussion	Remarks. Liogenys quadridens was redescribed for the first time by Burmeister (1855), who transferred it from Melolontha Fabricius, 1775 to Liogenys. Fabricius (1798) mentioned in the original description that the species is from “ India Orientali ” [East Indies], we interpreted that he meant West Indies instead. According to Burmeister (1855) and Harold (1869), L. quadridens occurs in Colombia and Guyana. Bates (1887) stated that this species occurs in “ Amazons ” but this record should be disregarded as it was surely based on the misidentification of other species of Liogenys. Bates (1887) also cited Panama, “ Volcán de Chiriqui 2500 to 4000 feet (Champion) ” but these specimens are here identified as L. quadridentata (based on our examination of these specimens in the BMNH). Frey (1969) cited the distributional limits of this species, from Florida (United States of America) (presumably based on port interception specimens) to Pernambuco (Brazil). In his key, Frey (1969) mentioned an intraspecific variation in the pronotal punctures and in the shape of the parameres, which he drew. At NHMB, we found the specimen from Pernambuco and it is here identified as L. piauiensis Cherman, 2017. Therefore, we refute the occurrence of L. quadridens in Brazil. Among the 41 specimens studied from seven collections bearing L. quadridens identification, we found one male from Nueva Gorgona (Panama) matching with the parameres drawn by Frey (1969), and a female of the same collection event which matches with L. quadridens lectotype. Liogenys quadridens has been cited by the United States Department of Agriculture (1969, 1971, 1974) in its list of intercepted plant pests, carried by aircraft, in unknown hosts. The first time cited (1967 – 1968) it was being carried from Panama, and the following (1971 – 1972) probably from Venezuela (United States Department of Agriculture 1969, 1974). This species was also cited as a tomato plant host from Maracaibo, Venezuela (Morales- Valles et al. 2003), and there exists reports of this species in imported ripe tomato fruit throughout the European and Mediterranean Plant Protection Organization (EPPO) region. Nonetheless, as it is not likely to be transported in tomatoes it is classified non dangerous (Grousset et al. 2015). In a study on scarab beetles abundance of a tropical dry forest in Colombia, García-Atencia et al. (2015) found that L. quadridens was the most abundant species (1,667 individuals), characterized as an important pest of semestral crops in the Colombian Caribbean. After studying several specimens of the Caribbean region we cannot confirm that all those specimens mentioned on the previous works are L. quadridens. Although we do believe that L. quadridens occurs in Colombia (based on the known distribution in Panama and Venezuela), we did not examine any specimens to confirm this country record.	en	Cherman, Mariana A., Basílio, Daniel S., Mise, Kleber M., Frisch, Johannes, Smith, Andrew B.

03D987EFAE67935E96F5FD92FA161BE5.taxon	discussion	Remarks. The lectotype of Liogenys quadridentata bears a green label “ Amphicrania 4 - dentata ”, a name credited to “ Klug MSC ” by Burmeister (1855) but not formally validated until Blanchard (1851) described the species. Burmeister (1855) listed the name as a junior synonym of L. quadridens. Soon after, Harold (1869) mentioned “ Amphicrania 4 - dentata ” as a synonym of L. quadridens, followed by “ in litt. ”, which means: “ new species mentioned in litteris (in correspondence), that will be described later in a separate paper ”. Harold (1869) probably did not see the L. quadridentata type series, so he did not associate the name “ Amphicrania 4 - dentata ” to the latter. After the mentioned synonymy of “ Amphicrania 4 - dentata ” (Burmeister 1855; Harold 1869), L. quadridentata was suggested to be a junior synonym of L. quadridens by later authors (Bates 1887; Dalla Torre 1913). We here confirm that L. quadridentata is a different species from L. quadridens. Liogenys quadridentata differs from L. quadridens (in parenthesis) mainly in the anterior margin of clypeus strongly bent upwards (not strongly bent); anterior and lateral tooth closer and acute angle between them (anterior and lateral tooth less close and right angle between them); mesotibia cylindrical in cross section (mesotibia subquadrate); pygidium noticeably convex, inflated medially in females (pygidium flat in both sexes); males with the protarsomere II longer (as wide as it is long), and the parameres are different in shape. The lectotype of L. quadridentata does not bear any locality data, and Blanchard (1851) did not mention the type locality in the original description. This fact agrees with Lacordaire (1855), who described the locality of L. quadridentata as “ Patrie inconnue ”. However, Burmeister (1855) and then Harold (1869) mentioned “ Columbia ” [current Colombia and Panama] as a locality record of “ Amphicrania 4 - dentata ”, which is likely the actual distribution of this species. Dalla Torre (1913) cited L. quadridentata from Montevideo (Uruguay). This is here interpreted as an error, which was reproduced by Blackwelder (1944) and subsequent authors. Due to the layout of Blanchard (1851) descriptions when they are contiguous, it is easy to attribute the type locality of one species to the next one. It is most likely that Dalla Torre (1913) attributed the type locality of Liogenys parva Blanchard, 1851 to L. quadridentata.	en	Cherman, Mariana A., Basílio, Daniel S., Mise, Kleber M., Frisch, Johannes, Smith, Andrew B.

The species is dedicated to Dr. Karla Schneider, biologist and curator of the Zoological Collection of the Martin-Luther-Universität, Halle-Wittenberg, Halle, Germany. Karla made the discovery of this new species possible by loaning the holotype from the MLUH to the ZHMB. This allowed its thorough examination during the visit of M. A. C. to these collections. This name should be treated as a noun in the genitive case.	en	Cherman, Mariana A., Basílio, Daniel S., Mise, Kleber M., Frisch, Johannes, Smith, Andrew B. T., Almeida, Lúcia M.

03D987EFAE63935896F5FF39FD961DCD.taxon	discussion	Remarks. Liogenys schneiderae Cherman, new species resembles L. quadridentata mainly in the body shape and size, color of the body and elytra, and in the quadridentate clypeus. However, L. schneiderae differs (L. quadridentata in parenthesis) in the clypeus being more rugose, with the impressions next to the frons more marked (not rugose); antenna with club shorter; anterior margin of pronotum slightly depressed throughout (not as so); elytral suture medially darker than the elytron (medially unicolored with elytron); metatibia flatter with inner margin abruptly subbasally produced towards apex (produced straight towards apex); ventrites I – IV with tubercles (without tubercles); and pygidium never inflated, with apex quadrate (pygidium convex in both sexes, inflated in females, pygidial apex rounded).	en	Cherman, Mariana A., Basílio, Daniel S., Mise, Kleber M., Frisch, Johannes, Smith, Andrew B.
