A new species of Hyperaspidini, Tenuisvalvae quadripunctata sp. nov. is
described and illustrated. The genus is now represented by 11 species, all
native of South America, and the new taxon is integrated into the existing
key to species of the genus. Ecological data for T. quadripunctata sp. nov.
and a list with prey and host plants to the species of the genus
Tenuisvalvae are provided.
The South American taxa of Hyperaspidini (Coleoptera:
Coccinellidae) were revised by Gordon & Canepari (2008)
and ten species of Tenuisvalvae (Duverger 1989) were recog-
nized. Most of them are important biological control agents.
Tenuisvalvae is characterized by having 11 articled
antennae with antennal bases partially concealed;
apical maxillary article slightly emarginated apically;
mandibulary retinaculum strongly curved, apex rounded;
clypeus and frons joined at feeble angle; protibia weakly
modified, narrow not flanged; abdominal postcoxal line
extended to or nearly to posterior margin, incomplete;
male ventrite VI weakly modified; female ventrite VI tri-
angular. Tenuisvalvae and Hyperaspis Chevrolat in
Dejean, 1833 are distinguishable only in the female gen-
italia. Tenuisvalvae have female genitalia with coxites
long, slender, while Hyeraspis coxites basically transverse
(Gordon & Canepari 2008).
The aim of the present work is to describe a new species
from Brazil collected in citrus crop. The new species is com-
pared to other species of the genus and comments on its
biology are included. The new taxon is integrated into
Gordon & Canepari (2008) key to species.
Material and Methods
In this paper, we describe a new member of the genus
Tenuisvalvae collected in Cerro Azul (24°96′24″ S, 49°30′63″
W, 318 m a.s.l.), Paraná State, Brazil, feeding on
Parthenolecanium perlatum (Cockerell, 1898) (Hemiptera:
Coccidae) in citrus (Citrus reticulata Blanco) crop. It was col-
lected both, immature and adults of the species.
Layer digital images were made at the Universidade
Federal do Paraná with a Leica DMC 2900 digital camera
attached to a Leica M205C stereomicroscope. Digital photos
were combined by using the software Leica LAS Multifocus.
