Three anomalies of Coleoptera (Carabidae, Staphylinidae, and Scarabaeidae) from Connecticut Author Ferreira, Raul N. text Insecta Mundi 2011 2011-04-15 2011 169 1 3 journal article 276122 10.5281/zenodo.5160620 74bd378f-b058-4b69-9567-a055d75bf747 1942-1354 5160620 Carabus nemoralis Muller (Carabidae) Figure 1 Carabus Linnaeus ( Carabidae , Carabinae , Carabini ) is represented in Connecticut by six species (Krinsky and Oliver 2001). This specimen was collected by Dr. M. K. Oliver in Connecticut , New Haven Co., Hamden in his backyard under a log on muddy soil on VII-19-1986 . The specimen presents a binary schistomely on the right maxillary palpus. The bifurcate maxillary palpus ( Fig. 1B ) shows the first segment longer, wider and truncate when compared with the normal left maxillary palpus ( Fig. 1A ), forming a bifurcation into two segments ( Fig. 1B, 1C ) of the same size and configuration as compared with the normal segments of the left maxillary palpus. According to Balazuc (1948) this anomaly could result from an exterior action on the larva which caused a split in the distal segment. When regeneration takes place the agent stays in contact and the wound remained divided into two, avoiding the fusion of the two split parts.
