Inflections: Plural adminicula.

Origin: A borrowing from Latin. Etymon: Latin adminiculum.

Etymology: < classical Latin adminiculum prop, support (see adminicle n.), in scientific Latin also accessory organ of a plant used for support, defence, etc. ( G. A. Scopoli Fundamenta botanica (1783) 20). Compare French adminicule support of a plant (1611 in Cotgrave).

a. Entomology. Originally: each of a number of minute spines or processes on the abdominal surface of certain subterranean insect pupae, used in locomotion (usually in plural; now rare). Later also: an unpaired accessory sclerite in the genitalia of certain male flies.

1826 W. Kirby & W. Spence Introd. Entomol. III. 255 The adminicula or short spines..with which the dorsal segments of the abdomen of some pupæ are armed.

1840 J. Duncan Introd. Entomol. (Naturalist's Libr.: Entomol. I) 91 When the segments are curved, the convex side, by means of these spines (called adminicula by Kirby), finds a point d' appui higher up than it occupied formerly.

1899 D. Sharp in Cambr. Nat. Hist. VI. vi. 327 It [sc. a lepidopteran pupa] is provided with spines, ‘adminicula’, by means of which..considerable changes of position can be effected.

1934 Ann. Entomol. Soc. Amer. 27 584 Adminiculum arms membranous, plaited, with a group of three large and five small spines near their bases.

2003 Jrnl. Kansas Entomol. Soc. 76 631 Gonapophyses not evident; adminiculum (or adminiculum and gonapophyses combined) simple, short, slightly indented apically.

b. Zoology and Palaeontology. Each of a number of tapering processes on the internal surface of the shell of certain articulated brachiopods. Usually in plural.

1953 J. A. Browne in Jrnl. & Proc. Royal Soc. New S. Wales 86 102 Adminicula, new term (sing. adminiculum), a pair of subvertical plates that may occur in the apical region of the ventral and sometimes also the dorsal valves, especially in very rostrate shells, extending from the inner tip of the umbo to the floor of the valve, and apparently to buttress the arch of the valve.

1978 N.Z. Jrnl. Geol. & Geophysics 21 524/1 Teeth (not seen) supported by low converging scapular-shaped dental plates. No adminicula.

2001 N. W. Archbold in I. Metcalfe et al. Faunal & Floral Migrations & Evol. in SE Asia-Australasia 81 A separate subgenus is warranted for the New Zealand material based on details of thickening of the ventral adminicula.

†2. Botany. Any accessory organ of a plant which serves to defend, strengthen, or support, such as a tendril, bract, stipule, etc. Cf. fulcrum n. 2a. Obsolete. rare.Apparently only attested in dictionaries or glossaries.
