TYPES: Male holotype and female paratype: in bush fallow near golf course, Ibadan, International Institute of Tropical Agriculture ( IITA), Nigeria N07°14', E03°30' (24 February 1982; A. Russell­Smith) ( MRAC 177.245 ) .

ETYMOLOGY: The ancient Greek word μαxαιpouωλιoν, arms shop, is used here as a noun in apposition. The species’ epithet points to the many sharp processes and apophyses on the ti of the male palp.

DIAGNOSIS: Males of H. machaeropolion are recognized by the complex RTA with long prongs of which the lower has a bifid, outward­curved tip whereas the superior prong is straight and much longer than the former. Females can be recognized by the large, trumpet­shaped first stretch of ID and the circular ID loops covering the ventral side of ST1.

MALE: Measurements. Total length 2.30; carapace 1.03 long, 0.78 wide; length of fe: I 0.92, II 0.95, III 0.81, IV 1.05. Leg spination. Fe: I rv 3; IV plt 1 rlt 1; ti: I, II vsp 6; mt: III plt 1 vt 1 rlt 0; IV plt 1 vt 2 rlt 1. Coloration. Carapace and legs yellow brown, chelicerae and sternum yellow. Abdomen yellow, no pattern. Palp. Tibia with large RTA, provided with long prongs, base knob shaped; inferior prong basically sickle shaped but with extra tooth just before tip giving it a bifid appearance; superior prong straight, slender, widening toward obliquely truncated tip; cymbium with large retrolateral bend with regular series of long setae; sperm

vsp 6; mt: III plt 1 vt 1 rlt 0; IV plt 1 vt 2 rlt 1. Coloration. Carapace, chelicerae and legs yellow. Sternum pale yellow. Abdomen yellowish white, no pattern. Genitalia. Epigyne with two heavily sclerotized, funnelshaped entrances of IDs (fig. 24i). Vulva: ID consisting of trumpet­shaped, wide, and very thick­walled outward­running first stretch associated with gland and connected to ST1 through diagonal stretch running inward, looped before entering globular ST1 (fig. 26f).

OTHER MATERIAL EXAMINED: 2 females, 1 male in 7–10­year­old fallow bush regrowth, Ibadan , IITA, elev. 300 m, Nigeria N07°30', E03°54' (4 July 1974; A. Russell­Smith) .

DISTRIBUTION: Known only from the type locality.
