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
