The tectofilosids are a group of filose amoebae with shells. These are composed of organic materials and sometimes collected debris, in contrast to the euglyphids, which produce shells from siliceous scales. The shell usually has a single opening, but in Amphitrema and a few other genera it has two on opposite ends. The cell itself occupies most of the shell. They are most often found on marsh plants such as Sphagnum.
This group was previously classified as the Gromiida or Gromiina. However, molecular studies separate Gromia from the others, which must therefore be renamed. They are placed among the Cercozoa, and presumably developed from flagellates like Cryothecomonas, which has a similar test. However, only a few have been studied in detail, so their relationships and monophyly are not yet certain.
In a recent classification, the group Tectofilosida was not used: Chlamydophryidae, Psammonobiotidae, Pseudodifflugiidae and Volutellidae were dispersally placed in Thecofilosea, while Amphitremidae was included in Labyrinthulomycetes.[2]

Tectofilosida o tectofilósidos es un orden de protistas del filo Cercozoa.[1] Son amebas filosas (con filopodios) que producen conchas compuestas de materiales orgánicos y de elementos recogidos, en contraste con Euglyphida, que producen conchas de escamas silíceas. La concha tiene generalmente una sola abertura, pero en Amphitrema y en algunos otros géneros tiene dos en los extremos opuestos. La célula en sí misma ocupa la mayor parte de la concha. Se encuentran generalmente en plantas de pantanos, como Sphagnum.
Este grupo fue previamente clasificado como Gromiidea, sin embargo, estudios moleculares los han separado de Gromia, y por lo tanto, han debido ser renombrados. Se clasifican en Cercozoa y se desarrollaron probablemente de flagellados como Cryothecomonas, que tiene una testa similar. Sin embargo, solamente algunos se han estudiado detalladamente, así que sus relaciones y monofilia no están todavía aseguradas.

텍토필로사목(Tectofilosida)은 리자리아계에 속하는 원생생물 목의 하나이다. 이전에는 이 분류군을 유각사상근족충목(有殼絲狀根足蟲目, Gromiida) 또는 유각사상근족충아목(有殼絲狀根足蟲亞目, Gromiina)으로 분류했다. 그러나 분자생물학적 연구를 통해, 이 분류군에서 유각사상근족충속(Gromia)을 분리하여 별도로 분류하고 이름을 바꾸었다. 이 분류군은 사족충류로 분류하고 있으며, 크리오테코모나스속과 같은 편모충류로부터 발달한 것으로 추정하고 있다. 그러나 상세 연구는 몇몇 사례에 불과하며, 그 때문에 각 분류군간의 관계와 단계통군인지 여부는 아직 확실치 않다.
