Abstract: Three genera, four species and the phenotype of Blattella germanica are recorded for the first time from Argentina. The distribution area of 15 species is expanded. The cockroach fauna from Argentina is still poorly known and currently represented by 45 genera and 100 species.
Keywords: Cariblattoides, Cockroach, Hormetica, Leuropeltis, Phenotype.
Resumen: Tres géneros, cuatro especies y el fenotipo de Blattella germanica se registran por primera vez en Argentina. El área de distribución de 15 especies se amplía. La fauna de cucarachas en Argentina actualmente representada por 45 géneros y 100 especies, es aún poco conocida.
Palabras clave: Cariblattoides, cucaracha, fenotipo, Hormetica, Leuropeltis.
The first revision of Blattaria from Argentina, carried out by Crespo & Valverde (2008), considered both material housed in museums and literature available on the subject. A catalog of the cockroach species known from Argentina was published subsequently (Crespo et al., 2010). These studies included the scattered information about the biodiversity of the order and analyzed the biotic affinities among the biogeographical provinces.
Valverde et al. (2012) recorded for the first time the genus Schistopeltis Rehn 1928, extending the distribution of S. lizeri Rehn from Bolivia to the Province of Chaco, Argentina. A few years later Crespo et al. (2015b) described a new species of Tribonium Saussure 1862, T. rothi Crespo, Valverde and Iglesias from the Province of Misiones and the number of species of the genus is increased with the new records of T. conspersum (Guérin-Méneville & Percheron) from the Provinces of Jujuy, Misiones and Tucumán, and T. neospectrum Lopes from Misiones.
Crespo et al. (2015a) cited for the first time Hypercompsa fieberi (Brunner von Wattenwyl) from the Provinces of Tucumán and Buenos Aires . Valverde et al. (2016) recorded Lanta borgesae Rocha e Silva & Vasconcellos from the province of Misiones. Both species were known from southeastern Brazil.
The collections of the Museo de La Plata (MLP), Instituto Fundación Miguel Lillo (IFML) and Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” (MACN) are again reviewed. The authors contributions housed in the Facultad de Ciencias Exactas y Naturales-Universidad de Buenos Aires (FCEN) are added. Taxa hierarchy follows the up-to-date database of the cockroaches of the world by Beccaloni (2014).
The aim of this communication is to update, from 2010 onwards, the generic and specific novel records and expand their known distribution area. Distributional data known from Argentina previous to the present study is listed in “Catalogue of Blattaria (Insecta) from Argentina” (Crespo et al., 2010) and we refer the readers to that study for complete records.

Blattella Caudell
Blattella germanica (Linnaeus) (Fig. 1B). The researchers of Centro de Investigaciones de Plagas e Insecticidas (CIPEIN), where this species is reared since 2014, observed the appearance of a new morph with a homogeneously coloured pronotum (Fig. 1a). We identified them as the phenotype of B. germanica, described by Roth (1985), lacking the characteristic black pronotal longitudinal bands of this species.

From the present study we found that three genera, seven species and a phenotype are registered for the first time from Argentina. The distribution area of 15 species is expanded. We must also add two genera and six species, cited in literature since 2010. Therefore, the number of genera and species of cockroaches found in Argentina is increased to 45 and 100 respectively (plus two species incertae sedis). The above mentioned B. germanica morph should be studied genetically.
