Diagnose : En ovale allongé ; brun noir ou brun rougeâtre sombre peu luisant. Glabre. Pattes brun rougeâtre. Tête granulée, les plus gros en avant de la suture frontale. Pronotum avec cinq bourrelets transverses et des sillons à ponctuation finement granulée ou ridée transversalement. Scutellum petit. Élytres avec 10 stries crénelées ; interstries avec une rangée longitudinale de granules qui à l'apex deviennent plus étroits et allongés.
Périodes d'observation (Adultes) : Pratiquement toute l‘année. Cependant, il est possible que le « vrai » germanus ne soit pas présent dans l'île car en réalité cette espèce fait partie d‘un complexe d'espèces nécessitant une étude approfondie.
Biologie-Ethologie : Espèce saprophage se trouve sur terrain sablonneux au pied des plantes ou sous les détritus végétaux jusqu'à 1000 m d'altitude. Vient aux lumières.
Biogéographie – Ecologie : Au sens large, espèce commune se trouvant dans pratiquement toute la région paléarctique et en Afrique du Nord.

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.
