A total of 17 species of Fissocantharis Pic is recorded from Guangxi, China. Six species are described new to science, F. sinensomima sp. n., F. sexcostata sp. n., F. basilaris sp. n., F. eschara sp. n., F. latipalpa sp. n. and F. biprojicientis sp. n., and two previously known species are redescribed, F. gracilipes (Pic, 1927) and F. sinensis (Wittmer, 1988). These species are presented with habitus of males, abdominal sternites VIII of females and genitalia of both sexes. Fissocantharis flavofacialis (Pic, 1926) is synonymized with F. angusta (Fairmaire, 1900); both were originally described in the genus Podabrus Westwood. Additionally, a key and a checklist of all the species of Fissocantharis from Guangxi are provided.

The species of Fissocantharis Pic, 1921 (redefined by
Fissocantharis flavofacialis (Pic, 1926) is considered to be a junior synonym of F. angusta (Fairmaire, 1900), which were both originally described in Podabrus Westwood, 1838 from Fujian, China, since no differences are found between them. A key and a checklist of all species from Guangxi are presented, as well as some additional distributional data are provided for some previously known species.
The material is preserved in the following collections. Primary types are returned to the collections from which they are borrowed or are otherwise deposited in public museums.
IZAS Institute of Zoology, Chinese Academy of Sciences, Beijing, China;
MHBU Museum of Hebei University, Baoding, China;
MNHN Muséum national d’Histoire naturelle, Paris, France;
NHMB Naturhistorisches Museum Basel, Switzerland;
ZFMK Zoologische Forschungsinstitut und Museum “Alexander Koenig”, Bonn, Germany.
The genitalia of both sexes and abdominal sternites VIII of females are dissected and cleared in 10% KOH solution, and the female genitalia is dyed with hematoxylin. Habitus photos are taken by a Leica M205 A microscope, multiple layers are stacked using Combine ZM (Helicon Focus 5.3). Line drawings are made with the aid of camera lucida attached to a Leica MZ12.5 stereomicroscope, then edited in CorelDRAW 12 and Adobe Photoshop 8.0.1.
Complete label data are cited for type specimens, quotation marks are used to separate data from different labels and a backslash “\” to separate data from different lines of the same label.
Body length is measured from the anterior margin of the clypeus to the elytral apex and body width across the humeral part of elytra. Morphological terminology of female genitalia follows that of Brancucci (1980). The abbreviations in the figures are as follows, ag: accessory gland; di: diverticulum; sd: spermathecal duct; sp: spermatheca; ov: median oviduct; va: vagina.

The elytra of the holotype are purple, but the coloration could be variable in cantharid species bearing a metallic shine, not only in Fissocantharis, but also in Themus Motschulsky. By contrast, the characteristics of the aedeagus and antennae of the male are much more stable and reliable, which are the basis of our determination of the additional specimens as this species.

Based on the examination of the types, F. flavofacialis (Pic, 1926) is considered to be a junior synonym of F. angusta (Fairmaire, 1900). Although the holotype of the latter species is female and the former is male, both species are originally described in Podabrus Westwood and attached with the same locality labels; also a large number of additional specimens do not show any difference between them. Therefore, we suggest to synonymize F. flavofacialis with F. angusta.

We are grateful to late Dr. Michel Brancucci (NHMB) not only for his providing a chance for the first author to visit and study in the Naturhistorisches Museum Basel for one year, but also for giving her many valuable suggestions in studying the taxonomy of Cantharidae. We are also indebted to Mr. Antoine Mantilleri (MNHN) for his kind help in accessing to the cantharid collections under his charge, to Dr. Wangang Liu (IZAS) for his help in examining some types in ZFMK and to Prof. Shanyi Zhou (Guangxi Normal University, China) for his support in the field trip in Guangxi. Thanks are due to the anonymous referee for their valuable comments on our manuscript and Mr. John MacDermott (USA) for correcting our English.
