Exempel på hur man kan använda PERITREME i en mening

• Each posterior spiracle (anal spiracle) lacks a clearly defined peritreme and each has three spiracular openings (in mature larvae).
• Larvae have two posterior spiracles with a thick and unbroken peritreme, and (like other Calliphoridae larvae) containing straight slits.
• Adult females of Macrochelidae have: an undivided dorsal shield bearing at least 28 pairs of setae, a sternal shield with three pairs of setae, a genital shield with one pair of setae and with a pair of conspicuous accessory sclerites beneath lateral margins, usually a ventrianal shield with 1–5 pairs of setae in addition to circumanal setae, peritreme usually looped around stigma, and movable cheliceral digit usually with a well-developed arthrodial brush at the base.
• Body elongate oval; head elongate, with nearly straight and carinate lateral margins; pronotum with posterolateral angles produced at base of scutellum; scutellum with a pair of deep foveae basally; peritreme large, occupying most of metapleurite, evaporatorium reduced.
• The form of the aperture and the peritreme and the channeled umbilical chink, bordered by an inconspicuous, rounded thread, place this species with Lissospira, although the texture of the shell is firmer and more porcellanous than any of the other species referred to it.
• Blattisociidae are mites with the following features: dorsal shield entire or laterally incised and with 18-43 pairs of setae; female with usually more than four pairs of marginal setae on soft cuticle; palptarsal apotele two-tined; fixed cheliceral digit with setiform pilus dentilis; peritreme usually extending from stigma at least to level of s2, and fused anteriorly with dorsal shield and broadly fused with exopodal shield beside coxa IV (except in Fungiseius clavulisetis); female spermathecal apparatus of the phytoseiid-type (except in Zercoseius); male spermatodactyl at least as long as movable cheliceral digit.
• They can be recognised by: prodorsum without transversal groove, sacs or tubes; suranal and aggenital shields separate; cheliceral bases usually separate (rarely fused or conjunct); palps stout with tibial claws at least 1/3 length of tarsus; peritreme absent.
• Its placement in the family Platyrhacidae is based on the presence of a broadened flattened telson, a broad flattened peritreme encircling the ozopores, paranota with a thin lateral edge, the ozopores shifted medially away from the lateral paranotal edge, and simple gonopods without a coxal process nor a prefemoral process.
• The aperture is rounded and slightly patulous in line with the axis, and in fully mature shells, a thick, white varicose peritreme is bevelled away from the aperture towards the thicker portion of the varix behind.
