phyllomorphy (filomorfi)

[ Phyllophaga (fi-lof'a-ga), n. pl. [NL. (Hartig, 1837), and the ovipositor formed of two saws ternately protruded. (b) A section of lamellicorn beetles which are leaf-eaters, as the chafers, conterminous with Macleay's two families Ano plognathidæ and Melolonthida. Latreille. Also Phyllophagi.-2. In mammal., a group of edentates corresponding to the Bradypoda, or sloths. Owen, 1842. phyllophagan (fi-lof'a-gan), n. [ IMG:content-0083.png:[blocks in formation] seuste. See Phyllop phyllopod (fil'ō-pod), a. and n. [ lop us ( -pod- ), II. n. A crustacean of the order Phyllopod a . Phyllopod a (fi-lop'ō-da), n . pl . [NL.: see phyllopod.] 1. An order of entomostracous crustaceans, the leaf-footed crustaceans, sometimes forming (with Ostracopoda and Cladocera) a suborder of Branchiopod a . In Latreille's cla ification the phyllopods were a section of his branchiopods, corresponding to the modern order of Phyllo pod a , and divided into (a) Ceratophthalma , with the genera Limnadia Estheria (composing the modern ily Estheriidæ ) and Artemia and Branch i pus (the modern family Branchipodidæ ), and (b) Aspidophora , with the genera Apus and Lepidurus (the modern family Apodidæ or Apusida). The feet phyllopods are very variable in number, and those of the locomotory series are membra nous or foliaceous, as implied in the name. Excepting in Branchipodidæ, the body bears a very large carapace, which in the Limnadiidæ takes the form of a bivalve shell with a hinge, closed by adductor muscles, into which the legs can be withdrawn. But this carapace is not a cephalothorax as is usual in crustaceans. Two pairs of antennæ are usually present. The mouth-parts are a pair of mandibles, two pairs of maxillæ, and in some forms a pair of maxillipeds. Phyllopods hatch from the egg in the nauplius stage; in some of them parthenogenesis occurs, and the eggs are notable for their ability to withstand desiccation without losing their vitality. Phyllopods inhabit chiefly fresh-water ponds, sometimes swarming in vast numbers. The species of Artemia, as A. salina, are known as brine - shrimps. The phyllopods are an old type, going back to the Devonian, and have some resemblance to trilobites. See cuts under Apus, Estheriidæ, and Limnetis. 2. In conch., in J. E. Gray's cla ification (1821), one of several orders of Conchophora, containing dimyarian bivalve mollusks having the foot lamellar or elongate.
