- Tegoribatid with lamellae separated. Pteromorphs immovable. Notogaster with posterior overlapping tectum............. 7

2. Interlamellar setae present............................................................................... 3

- Interlamellar setae absent............................................................................... 5

3. Notogaster with 10 pairs of well-developed, setiform setae. Octotaxic system expressed as saccules......................................................................... Scutozetes 1 Hammer, 1952 (= Neolepidozetes Hammer, 1977 )

- Notogaster with 10 pairs of minute setae................................................................... 4

4. Setae le located at the extreme of the lamellar tectum. Notogastral saccules developed as filiform tubules. Infracapitulum diar- thric with expanded mentotectum........................... Tegoribates 2 Ewing, 1917 (= Lepidoribates Sellnick, 1920 )
