Entomobryomorpha Börner, 1913
Identification
Abdominal segmentation dorsally distinct. Prothoracic dorsal setae absent. Prothoracic tergite indistinct. Trunk always elongate
(1).
Poduromorpha typically have short legs and antennae while Entomobryomorpha typically have long legs and antennae. Although there are ofcourse exceptions: Entomobryomorpha adapted to live in the soil also have short legs and antennae. To be sure, check the presence or absence of the 1st thoracic segment in dorsal view. This is sometimes hard to see and will require some practise. In Poduromorpha the segment is present. In Entomobryomorpha it is absent. In other words, in dorsal view, Poduromorpha count 3 thoracic segments, while Entomobryomorpha count only 2 thoracic segments, in dorsal aspect. Ofcourse both have 3 thoracic segments, given they have 3 pairs of legs, but in Entomobryomorpha the dorsal tergite of the 1st thoracic segment is reduced completely. (Comment by Frans Janssens.)
