bristle = a stiff hair, usually short and blunt [5] chaeta = (pl. chaetae). a joined outgrowth of the skin, originating in a cup-like pit at the end of a pore canal, essentially an elongated epidermal cell [5] hair = a slender flexible filament of equal diameter throughout [5] macrochaeta = (pl. macrochaetae). the long bristles occurring singly on the body of Diptera [5] macrotrichia = in Diptera the larger microscopic hairs on the surface of the wings [5]; single or branched hairs, sometimes called setae; these are hollow, longer than microtrichia, and arise from a pit or socket; they may be fine or thickened [6] microchaeta = (pl. microchaetae). small bristles, as opposed to macrochaeta [5] microtrichia = minute, hair-like structures found on the wings of certain insects; they resembles small covering hairs, but the absence of basal articulation distinguishes them; fixed hairs; aculei [5]; minute non-movable hairs formed from cuticle; may produce an impression of cloudiness or colour [6] pile = a hairy or fur-like covering; thick, fine, short, erect hair, giving a surface appearance like velvet [5] pruinescence = a minute dust or bloom covering certain insects [5] pubescence = downy; clothed with soft, short, fine, closely set hair [5] scale = a flat unicelluar outgrowth of the body-wall, of various shapes and probably a modified seta [5]; modified hairs or setae; they are flattened and coloured but otherwise essentially similar to setae in their structure [6] seta = (pl. setae). macrotrichia; commonly known as hairs; hollow structures developed as extensions of the epidermal layer; slender, hair-like appendages [5] setula = (pl. setulae). a small stiff bristle or seta; in Diptera, the small spine ["thorn" in the original text] at the end of the subcosta [5] spine = a multicellular more or less thorn-like process or outgrowth of the cuticula not separated from it by a joint - or: a large seta provided with a calyx or cup by which it is articulated to the cuticula [5]; non-movable hairs formed from cuticle, thicker and stronger than microtrichia [6] spinula = (pl. spinulae). a small spine; one of the spinous processes at the apex of the tibia, also called spines, spurs or heels; a hair-like appendage of the cuticula [5] spur = a spine-like appendage of the cuticula, connected to the body-wall by a joint [5]; thick cuticular hairs or spines on the legs of certain insects [6] tomentum = a form of pubescence composed of matted, wooly hair; in Diptera applied to a covering of short, flattened, more or less recumbent, scale-like hair which merges gradually into dust or pollen [5]
