查看更多>>摘要：The Holarctic genus Laricobius (Derodontidae) is reviewed and a key to the species provided. There are 21 known species and those with known life history are predators of adelgids. The type specimen of L. minutus Nikitsky was lost prior to this study and types of L. caucasicus Rost were never located, though one specimen which lacks the abdomen is attributed to this species. One new species is described (Laricobius naganoensis n. sp.) and lectotypes were designated for L. erichsonii Rosenhauer and L. sahlberg Reitter. Europe has one described species, North America 3, and Asia 17. A cladistic analysis, based on 20 species, resulted in two broad groups, one which is confined to south-eastern Asia and Himalaya and has more shortened species with a narrower pronotum lacking explanate margins, and a more widespread Holarctic group, which is more typical of the genus type, being more elongate, with a transverse, fully explanate pronotum. The latter group includes four Asian species without ocelli, collected from Tsuga (hemlock) infested with Adelges tsugae Annand.

The complex is divided into two species groups, depressicolle and flohri. A key to all species groups of the subgenus Carabomimus (depressicolle, digueti, flohri, politum and striatulum) inhabiting this area is included, whereas C. bulleri (Beheim & Breuning, 1943) was left unassigned. Another key to all five species of the complex (species groups depressicolle and flohri) is likewise included. It is described C. flohri zirostense ssp. n. (Mexico: Michoacan), and the previously synonymized C. lesnei Breuning, 1931 and C. gebieni Breuning, 1931 are restablished as valid taxa. C. asper (Jeannel, 1940) is downgraded as subspecies of C. depressicolle Chaudoir, 1869, whereas C. altipeta (Jeannel, 1940) and C. sylvestre (Lassalle, 2009) are ranked as species. C. digueti colimaense (Lassalle 2009) is considered to be a subspecies of C. flohri.

It appears to be an Adesmia (Fabaceae) specialist and its specific name refers to its death posture which is similar to that found in other small bees that visit the same genus of plant. A key to the Chilean species of the genus is provided.
