| Hymenolepis lanceolata | A tapeworm of aquatic birds, rarely found in humans. (05 Mar 2000) |
| Hymenolepis nana | The dwarf or dwarf mouse tapeworm; a small tapeworm of man, sometimes found in great numbers in the intestine; the cysticercoid can develop by two pathways: in the final host, with the egg from one human directly infective to another human host, in which both larval and adult stages occur, or through two hosts, an insect (or crustacean) intermediate and a vertebrate final host, the obligate two-host cycle of most cyclophylidean cestodes; in addition, Hymenolepis nana can internally reinfect the same human or rodent host, producing a massive reinfection. (05 Mar 2000) |
| Hymenolepis nana fraterna | A race, strain, or subspecies of Hymenolepis nana adapted to mice, although infectivity to humans may remain; the human form, Hymenolepis nana, presumably is derived from the rodent strain. (05 Mar 2000) |

| hymenoptera | <zoology> An extensive order of insects, including the bees, ants, ichneumons, sawflies, etc. They have four membranous wings, with few reticulations, and usually with a thickened, dark spot on the front edge of the anterior wings. In most of the species, the tongue, or lingua, is converted into an organ for sucking honey, or other liquid food, and the mandibles are adapted for biting or cutting. In one large division (Aculeata), including the bees, wasps, and ants, the females and workers usually have a sting, which is only a modified ovipositor. Origin: NL, fr. Gr. Membrane-winged; skin, membrane + wing. Source: Websters Dictionary (01 Mar 1998) |
