Scutigerellidae

Symphylans in this family usually measure more than 4 mm in length. In this family, the head and neck are distinctly separated. The antennae usually feature more than 20 articles and a large branched organ on the most distal article. The adult in this family features 15 simple tergites, with the first tergite reduced in size, and 12 pairs of legs. Each leg pair corresponds to a single tergite except for the fourth, sixth, and eighth leg pairs, which each correspond to two tergites. The first pair of legs is well developed and more than half the length of the next pair. Well developed styli protrude from the base of the legs, each with two or more setae.{{Cite book |last1=Szucsich |first1=Nikola |url=https://www.worldcat.org/oclc/812207443 |title=The Myriapoda.

Fossils of symphylans are rare and limited to specimens found in amber. This family includes three species described from fossils. The first fossil symphylan to be described was Scutigerella dominicana, which was described in 1995 based on two juvenile specimens found in the Dominican Republic in amber from 25 to 40 million years ago.{{Cite journal |last=Poinar |first=G.

The third fossil symphylan in this family, Hanseniella baltica, was also described in 2004 based on a female subadult, also found in Baltic amber. Both S. baltica and H. baltica were found in Eocene amber from 40 to 50 million years ago, making these two species the oldest described species in this family.{{Cite journal |last=Scheller |first=Ulf |last2=Wunderlich |first2=Jörg |date=2004 |title=Two fossil symphylan species, Scutigerella baltica n. sp. and Hanseniella baltica n. sp.
