Cercopoidea types (Hemiptera-Cicadomorpha) housed at the Museo de la Plata entomological collection (Argentina)

Type material of 11 species from seven genera of Cercopoidea is housed at the Entomology Division of the Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata. The types listed herein correspond to species described by C. Berg (10 spp.) and Lallemand (1 sp.). The collection contains 24 type specimens. Lectotype and paralectotypes of Deois (Deois) knoblauchii (Berg), Kanaima katzensteinii (Berg), Mahanarva (Ipiranga) aguirrei (Berg), Tomaspis argentina Berg [= Deois terrea (Germar)], T. perezii Berg [= Deois terrea (Germar)] and T. platensis Berg are designated. Comparison of their original descriptions with the label information supports the existence of 2 holotypes, 6 lectotypes, 10 paralectotypes and 6 syntypes. The following information is given for each species: original species names, taxonomic catalogue, bibliographic references, type category, number of specimens, gender, Museo de La Plata code numbers, and transcription of data from labels (country, province, locality, date of collection, collector’s name, and hosts). Information about subsequent nomenclatural changes with corresponding references, the state of preservation of the specimens in each series and pictures of each species are also provided. Key-Words.

INTRODUCTION
The Cicadomorpha encompasses leafhoppers and treehoppers (Membracoidea), cicadas (Cicadoidea) and spittlebugs (Cercopoidea), by far the most diverse plant-feeding hemipteran superfamily. Due to their piercing-sucking feeding behavior, these insects are an important group of vectors of plant pathogens (Nielson, 1968). The superfamily Cercopoidea, with approximately 3,000 species, are divided into three families: Cercopidae, which are efficient spittle-producers (including subfamilies Aphrophorinae Amyot &Serville, 1843 andIschnorhininae Schmidt, 1920); Clastopteridae (including subfamily Clastopterinae Dohrn, 1859 and Machaerotinae Stål, 1866), inefficient spittle-producers and tube-dwellers; and the New-World tropical Epipygidae which probably lay exposed eggs and have free-living nymphs (Carvalho & Webb, 2005;Hamilton, 2001Hamilton, , 2013. At present, Cercopidae Ichnorhininae, represent a very diverse group, has approximately 475 species distributed in the Neotropics (Carvalho & Webb, 2005;Hamilton, 2013). 24 species of eight genera were registered in Argentina (Foieri, 2017) and eight species of five genera were deposited in the collection of Museo de La Plata. Aphrophorinae is integrated by 670 species, described in 154 genera widely represented in the world (Metcalf, 1962;Hamilton 2015). Only two species of two genera were recorded in Argentina and the type material of one of them was deposited in the Museum collection. For Clastopteridae Clastopterinae, approximately 152 species of 7 genera were recorded for America, Africa and Southeast Asia, 100 species were recorded from America and only two species of the genus Clastoptera Germar are present in Argentina (Metcalf, 1962;Hamilton, 2015); both were deposited in the Museum collection.
The purpose of this catalogue is to provide a record of the cercopid types present in the entomological collections of the Museo de La Plata, Argentina as part of a series of contributions on the Auchenorrhyncha housed there (Paradell et al., 2008(Paradell et al., , 2010Marino de Remes Lenicov et al., 2010, 2015Paradell & Defea, 2017).
Publications documenting the type material housed at different museums and other scientific institutions are recommended by the 4th edition of the International Code of Zoological Nomenclature (Article 72 F4, ICZN, 1999).

MATERIAL AND METHODS
For each species we provide the following information: -Names of the species. -Bibliographic references.
-Category of types.
-Gender and number of the specimens/category. -Distribution data (geographic locations with longitudes and latitudes) associated with types specimens. -Original description and traslation is added for lectotype and paralectotypes.
A four-digit code number followed by a slash and second number indicate the type category, according to the present status and rules of the Museo de La Plata Entomological Collection (MLP): /1, lectotype; /2 and subsequent numbers, paralectotypes. Data on labels were recorded as an exact transcription of the text on labels associated with each specimen: country, province, locality, collecting date, collector's name, and host, when indicated. Additional information on the type specimens is included as "Remarks".
All type specimens were identified with a rectangular red printed label following the institution´s policy for the collection, as well as the original hand-written labels.
The information of labels of each specimen were checked with the original description to verify the type status of each species. Lectotypes and paralectotypes were designated when enough information was available to select a specimen as bearer of the name from among a single or several specimens of the series. For these taxa, the original descriptions were transcribed and translated (indicating in quotation marks the originals).
Full bibliographic references for species and pictures of each species are provided. Photographs of the holotypes, lectotypes and syntypes were made using a LEICA EZ5 stereoscopic microscope with. RRID 18 HD digital camera adapted to the microscope. Digital images were assembled using Combine ZM open software (Hadley, 2011).

Head with apex subangular, slightly punctured on each side, with a slightly marked median carina; frons convex, with a strongly marked carina; pronotum opaque anterioly, very slightly carinated (medio obsoletissime carinato); scutellum deeply punctured, reddish black at apex; tegmina bend downward at apex, slightly narrowing towards apex, red at base, first costal spot subtriangular and the second quadrangular; wings sub-hyaline or darkness; prosternum darkish; mesosternum and metasternum, dorsal and ventral surface of the abdomen and legs dark reddish; femora darkened; basal spine of the metatibia small.

Remarks: All the specimens labelled as "typus" by Berg and treated as syntypes by Carvalho & Webb (2005) are designated here as lectotype and paralectotypes (ICZN, art. 74.1.1). This species was originally described as Tomaspis Amyot & Serville by Berg (1879), transferred to Deois (Pandysia) by Fennah (1953: 357) and later placed as Deois (Deois) by Costa & Sakakibara (2002: 197). The original publication indicates that five specimens were used for the description of the species, but only three are deposited.
