Two new species from Brazil

Cis gumiercostai

Cis fiuzai

Cis comptus group


In this paper, we present the descriptions of two species of Cis Latreille, C. fiuzai sp. nov. and C.
gumiercostai sp. nov., based on external morphology including male genitalia. We propose that
these new species belong to the C. comptus group. These species are known from Araponga and
Cardeal Mota (Minas Gerais State, Southeastern Brazil), respectively. Cis gumiercostai is the fourth
species of Ciidae reported from the Cerrado vegetation (Brazilian Savana).

Cis Latreille, 1796 (Coleoptera: Ciidae) is a worldwide genus, with around 370 described species (Abdullah 1973) and dozens of new species waiting to be described. The uncertainty about the limits of this genus have already led to many cases of synonym, indicating that it urges a revision. The subgeneric division of Cis is unclear and not always adopted.
Therefore, species groups are used more commonly than subgenera in the genus Cis. However, it should be emphasized that these species-groups are just taxonomic tools, and cannot be assumed as being monophyletic clades.
In the last eight years, the C. comptus group was one of the most studied speciesgroups of Cis. Since the delimitation of the group, the number of known species raised from four (Lawrence 1971) to nine (Lopes-Andrade et al. 2003). In this work, we describe two species of Cis from Brazil, C. fiuzai sp. nov. and C. gumiercostai sp. nov., both
belonging to the comptus group.

Specimens of C. fiuzai sp. nov. and C. gumiercostai sp. nov. were collected in bracket
mushrooms from two localities, Araponga and Cardeal Mota, respectively, both in Minas
Gerais State (Southearstern Brazil).
For external morphology, some specimens were analysed and photographed in a scanning electron microscope. The specimens were dehydrated in a series of alcohol and acetone solutions, critical point dried, mounted on stubs and sputter-coated with gold.
Genitalia extraction and examination followed Lopes-Andrade et al. (2003). Ten paratypes
(5 males and 5 females) from each species were measured under a stereomicroscope
(Leica MZ 12) according to Lawrence (1987).
We also analysed the male genitalia of other species of the comptus group for comparison: C. comptus Gyllenhal; C. leoi Lopes-Andrade et al.; C. striolatus Casey; C. tauriensis Królik; and C. versicolor Casey. Schematic representations of the male genitalia were
provided by some authors for the following species: C. orius Kompantsev and C. seriatocribratus Reitter (Kompantsev 1996); C. striatulus Mellié (Lawrence 1971). The morphology of the male genitalia of C. clavicornis Baudi is unknown for us.
