Conjunctae

Belongs within: Carabidae.Contains: Trechodini, Tasmanorites, Geocharis, Patrobini, Scaritinae, Trechinae, Brachininae, Harpalinae, Amblytelus, Mecyclothorax, Broscinae, Elaphrinae. The Conjunctae are a major clade of carabid ground beetles distinguished primarily by the presence of conjunct mesocoxae, with the coxal cavities surrounded by the mesosternum and metasternum. Members of this clade include the large subfamilies Harpalinae and Trechinae, though… Continue reading Conjunctae

Lebiini

Belongs within: Harpalinae.Contains: Tetragonoderus, Lebia, Pericalina, Cymindis, Dromius, Demetrida, Anomotarus. The Lebiini represent a diverse group of carabid beetles that has proven difficult to define morphologically (Ober & Maddison 2008). Representatives include the primarily arboreal genus Calleida, members of which have the tarsomeres longitudinally sulcate dorsomedially (Ball & Bousquet 2001). <==Lebiini (see below for synonymy)B14… Continue reading Lebiini
