Detepwani ni ndege wa nusufamilia Cerylinae katika familia Alcedinidae. Spishi kubwa zinaitwa mkumburu au zumbulu. Wanafanana na midiria lakini spishi nyingi ni wakubwa zaidi na zote zina kishungi. Kwa kweli baina ya spishi hizi kuna zile kubwa kabisa za familia hii, lakini American pygmy kingfisher ni mdogo sana. Takriban spishi zote zina rangi ya majani ya metali mgongoni na nyekundu kidarini, lakini detepwani wa kawaida ni mweusi na mweupe tu.
Detepwani hubobea katika kukamata samaki lakini hula gegereka, vyura na wadudu pia. Huchimba tundu katika ukingo wa mto ambalo ndani lake jike huyataga mayai 2-5.

Phylogeny of the Cerylinae Cerylinae Cladogram based on Andersen et al. (2017)[1]
The water kingfishers or Cerylinae are one of the three subfamilies of kingfishers, and are also known as the cerylid kingfishers. All six American species are in this subfamily.
These are all specialist fish-eating species, unlike many representatives of the other two subfamilies, and it is likely that they are all descended from fish-eating kingfishers which founded populations in the New World. It was believed that the entire group evolved in the Americas, but this seems not to be true. The original ancestor possibly evolved in Africa – at any rate in the Old World – and the Chloroceryle species are the youngest ones.
Evidence from molecular phylogenetic studies suggests that the Cerylinae originated in Asia and have colonised the New World on two occasions: the first time was around 8 million years ago by the Chloroceryle and the second time was around 1.9 million years ago by the common ancestor of the ringed kingfisher and the belted kingfisher in the genus Megaceryle.[1]
The subfamily Cerylinae contains nine kingfisher species and is divided into three genera:[2]
