Trivial: applied to a name, means specific as opposed to generic, or popular as opposed to technical. Trivittate: with three stripes or vitta. Trochalopoda: Heteroptera in which the posterior coxae are nearly globose and the articulation is a ball and socket joint: see pagiopoda. Trochanter: a sclerite, sometimes divided, between the coxa and femur sometimes fused with the femur. Trochanterellus: see apophysis. Trochantine: the basal part of the trochanter when it is two-jointed: in Coleoptera, a piece often present on the outer side of and sometimes movable on the coxa; also the small sclerite connecting the coxa with the sternum in Dytiscidae: in Neuroptera and Trichoptera the posterior separated part of the coxa: in Orthoptera, a narrow longitudinal sclerite between mandible and gena. Trochiformis: cylindro-conic. Trochlea: the thickened base of the hind wings in Cicada: in Trichoptera a small elliptical space at base of hind wing behind origin of median vein. Trochlearis: pulley-shaped; like a cylinder contracted medially. Trochus: that part of an articulated body inserted between the joints. Trophi: the mouth parts collectively, including the labrum: see buccal appendages. Trophobiosis: see Symbiosis. Tropical: is that faunal region which covers the southern part of the peninsula of Florida, the greater part of Central America, the lowlands of southern Mexico south of the table land, and a narrow strip on each side of Mexico which follows the coast northward into the United States. Tropico-politan: occurring in all tropical regions. Trumpets: breathing tubes of mosquito pupae. Truncate: cut off squarely at tip. Truncature: the truncation or point squarely cut off. Truncus: the trunk or thorax. Trunk: the thorax as a whole: the body. Tryptic: acting like tripsin, the proteolytic ferment of the pancreatic fluid. Tube: a slender, hollow, cylindrical body: specifically applied to the anal siphon or respiratory tube of mosquito larvae. Tubercle: a little solid pimple or small chitinous button: really a ring, which may or may not give rise to a seta. Tubercles: on the thoracic and abdominal segments of caterpillars are anterior trapezoidal; posterior trapezoidal; lateral; posterior stigmatal; anterior stigmatal; sub-primary subventral; pedal and adventral: all of which see. Tubercula: an elevated triangular process at the anterior angle of the thorax specifically in Hymenoptera. Tuberculate -ose: formed like a tubercle: a surface covered with tubercles. Tubercule -ulum: a small tubercle. Tuberculiform: shaped like a pimple or tubercle. Tuberculose -ous: covered or set with tubercles. Tubulifera: Hymenoptera, in which the terminal segments of abdomen are retracted, but may be extended, tube-like: Thysanoptera in which there is no ovipositor and the terminal segments of abdomen are tubular. Tubulous -ose: formed like a tube: fistulous.
