Newly collected male and female specimens of the leafhopper Kolla albescens Jacobi, 1943 from the type-locality (Northeast China), are identified as Pagaronia albescens (Jacobi), comb. n. (Evacanthinae: Pagaroniini). A redescription of the species is provided together with habitus photographs of the male and female and illustrations of the male and female genitalia. P. continentalis Anufriev, 1970 is placed as a junior synonym of P. albescens syn. n.


Auchenorrhyncha, China, new combination, Pagaroniini, taxonomy


The leafhopper Kolla albescens was described by Jacobi (1943) based on a female specimen from Northeast China. In Young’s (1986) Cicadellinae revision he did not examine the type specimen of Kolla albescens so placed it in Kolla following Metcalf (1965). Although Wilson et al. (2009a, b) provided body images of the type specimen, the lack of a male specimen has prevented the species being formally redescribed or revised. Fortunately, we have been able to collect several specimens from the type locality in Northeast China of Kolla albescens. Based on colour, external features and the male genitalia, this species should be included in the leafhopper genus Pagaronia Ball (Evacanthinae: Pagaroniini). Subsequent comparison with figures of Pagaronia in Kwon (1981) indicated that it was a senior synonym of Pagaronia continentalis Anufriev (1970), the only species of Pagaronia from China (Kwon and Huh 2001). Habitus photographs of the male and female and illustrations of the male and female genitalia of Pagaronia albescens are provided.

Material and methods

The male and female genital structures were prepared according to the techniques described by Oman (1949) and Mejdalani (1998), respectively. The dissected parts are stored in small vials with glycerin and attached below the specimens. The morphological terminology adopted herein follows mainly Young (1986), except for the facial areas of the head (Hamilton 1981; Mejdalani 1998), the leg chaetotaxy (Rakitov 1998) and that of the female genitalia (Nielson 1965; Davis 1975; Mejdalani 1998). All specimens studied are housed in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).

Material examined.

3 males and 5 females, China, Liaoning Province, Henren County, Benxi Laotuding Preserve, 19 to 21 July 2011, coll. Fan Zhi-hua and Yu Xiao-fei; 1 female, China, Jilin Province, Mt. Changbai, 24 July 2011, coll. Yu Xiao-fei.


This species was described from a single female specimen (holotype) from “Gaolinzsy” (NE China). The type specimen, deposited in Deutsches Entomologisches Institut im ZALF, Müncheburg, Germany, has not been examined but our material has been compared with an image of the type (see introduction). The identity and reference for the Pagaronia species recorded from China in Hayashi et al. (2010) and Kamitani et al. (2012) was established as Pagaronia continentalis recorded by Kwon and Huh (2001) (M. Hayashi, pers. com.).


Sincere thanks to Prof. Masami Hayashi (Saitama University, Japan) for giving us important information on the identity and reference for the Pagaronia species recorded in Hayashi et al. (2010) and Kamitani et al. (2012). We also thank Gabriel Mejdalani (Departamento de Entomologia, Museu Nacional, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil) and C. A. Viraktamath (Department of Entomology, University of Agricultural Sciences, India) for reading the manuscript and making some corrections. We are very grateful to Yu Xiao-fei (GUGC) and Jiao Meng (GUGC) for making the figures of the male genitalia. Thanks to Fan Zhi-hua (GUGC) and Yu Xiao-fei for collecting specimens.
