Diagnose : Petite punaise jaunâtre à brunâtre dont le scutellum atteint l'extrémité de l'abdomen. Scutellum et pronotum verruqueux avec une texture à reliefs irréguliers. Angles huméraux du pronotum saillants mais arrondis. Bords antérieurs du scutellum avec chacun une petite callosité ronde et blanche. Connexivum (bord de l'abdomen) alternativement sombre et clair. Détermination : Simple.
Espèces proches : Sa petite taille et l'aspect verruqueux du pronotum et du scutellum sont absolument caractéristiques.
Période d'observation : Fin mai à septembre.
Biologie-éthologie : Elle ponctionne les graines, ni trop vertes, ni trop desséchées, de petites crucifères montagnardes, les alyssons et les passerages. Souvent localisée sur les graines ou à la base des touffes de plantes âgées, dans des massifs importants de plantes, plutôt que sur des plants isolés ou jeunes.
Biogéographie et écologie : Espèce méditerranéenne répandue vers l'est jusqu'en Iran, l'ouest de la Sibérie et au Kirghizstan. Elle est localisée sur les reliefs à influences conjointes méditerranéenne et montagnarde (étage supraméditerranéen), le plus souvent entre 900 et 1 700 m d'altitude : causses ou plateaux à sols calcaires ou sableux, pelouses rases, coteaux pierreux, sols de terre brune et bord des chemins arides. C'est une espèce très rare et difficile à observer en raison de ses capacités de camouflage avec les graines d'alyssons et les petits fragments de terre, et de thanatose, d'autant qu'elle se laisse tomber au sol à la moindre alerte.
The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.

Current distribution in metropolitan France
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.

Certain presence
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
Probable presence
This status is based on one or more of the following criteria:
search of species incomplete but presence of supportive environments;
ecology of the species consistent with the hypothesis of his presence;
the last reliable sighting is older than 10 years compared to the reference date, no recent specific research and no presumption of extinction from that date [vertebrates, invertebrates and plants well studied (rhopalocera, grasshoppers, dragonflies ...)] ;
the last reliable observation being older than 20 years, no recent specific research and no presumption of extinction from that date [poorly known taxa: fungus, many invertebrates...].
Probable or certain absence
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
intensive but unsuccessful targeted research;
lack of adequate environments;
unobserved species while its presence is easily detected;
unlikely presence for historical or biogeographical reasons.
This status must be assigned to a department in which the presence of the species is casual.
Absence due to a proven extinction
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
No information
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
