Exempel på hur man kan använda METATHORAX i en mening

• They are characterized by a structure in the metathorax called the nodular sclerite or epaulette, which separates the tympanum and the conjunctiva in the tympanal organ.
• These are often present in adults as well, but adults also develop a pair of glands on the metathorax (third segment of the thorax), these being the metathoracic scent glands.
• The metathorax is solidly fused to the pronotum and mesothorax; moreover, the prothorax is best developed in Pompilidae and Scoliidae because wasps in these families use their forelegs to dig.
• During the final ecdysis, the anatomy is rearranged and the glands end up in the metathorax, opening laterally through ostioles between the mesothoracic and metathoracic pleura.
• The posterior portion of the fly's metathorax, or scutellum, has a pair of stout processes, and often the laterotergite (one of a number of lateral flanges) of the postnotum (a small dorsal sclerite on the insect thorax posterior to the notum) has a dome-like swelling or spine-like process.
• Those include the absence of a wasp waist (thorax and abdomen abut without constriction), presence of cenchri on the metathorax to fix the wings at rest, presence of an antennal grooming apparatus on tibia and first tarsomere of the fore leg, and presence of a molar tooth on the mandible.
• intersegmental thoraco-abdominal membrane : intersegmental membrane between the metathorax and the first abdominal sclerites.
• This species has sparse, yellow to brown pubescence (hairs) on the ventral surface of the metathorax, and is glabrous on the metepimeron on the side of the metathorax.
• —Black; head and thorax closely and moderately punctured; the mesothorax smooth, impunctate and shining on the disk; metathorax rounded behind; abdomen shining rather finely punctured, most closely so at the sides above; the pubescence entirely black, except that on the anterior tarsi beneath, which is ferruginous; the claws of the tarsi ferruginous; wings fusco-hyaline, with a darker cloud beyond the enclosed cells, and adorned with a bright purple and coppery iridescence.
• Palpi upturned, the 2nd joint broadly scaled in front, the 3rd porrect (extending forward) and lying on the hair of 2nd joint; maxillary palpi filiform and as long as the labial; frons rounded; antennae of male minutely ciliated; patagia extending beyond the metathorax; tibiae with the outer spurs half the length of the inner; abdomen long, male with the anal tuft large.
• White, although the palpi, antennae, a border to tegulae, a band across thorax and patagia, and a spot on the metathorax are scarlet.
• It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that separates the head from the thorax; and the pleuron, a lateral sclerite of the thorax.
• The head and thorax are ochreous tinged with fulvous; palpi and sides of frons black; a large black patch on prothorax with streak from it to metathorax; pectus black; femora crimson fringed with ochreous hair, the tibiae and tarsi black; abdomen pale crimson with a blackish dorsal streak on medial segments, the ventral surface ochreous, lateral and sublateral black points on medial segments.
• The most obvious is that the thorax is divided into three sections, the prothorax, the mesothorax, and the metathorax.
• The insects, wingless in both sexes, have a pair of spines on the head and on the anterior margin of the mesonotum and a ring of four spines on the posterior margin of the meso- and metathorax.
• Female nymphs in particular have bright orange areas on the undersides of the femura, the meso- and metathorax, the intermediate membranes of the abdominal segments and other smaller orange areas on the sternites of the abdomen itself.
• Their species are relatively spiny, have distinct lateral spines along the margins of the meso- and metathorax and an isosceles triangle on the anterior mesothorax, reaching about halfway down the mesonotum.
