Trypodendron domesticum

Scientific profile

Trypodendron domesticum is a very small beetle, with a mean body length of 3.45 mm and a mass of just 2.99 mg. The body is compact and notably rounded (body roundness 0.962). The pronotum and body width both measure 1.296 mm, while the elytra are 2.069 mm long. The head is small, 0.499 mm long and 0.809 mm wide, with an eye area of 0.061 mm² and comparatively short antennae of 0.715 mm. The mandibles are slender, with an aspect ratio of 0.223. The legs are delicate: the front femur is 0.727 mm long, the mid femur 0.696 mm, and the hind femur 0.704 mm; the corresponding tibiae are 0.576 mm, 0.596 mm and 0.618 mm respectively. The wings are fully formed, with a span of 5.095 mm, an area of 6.644 mm² and a width of 1.713 mm, yielding a wing loading of 0.45 and an aspect ratio of 2.974. The residual wing loading of 0.441 indicates a higher value relative to body size. Overall colouration is pale, reflected in a colour lightness value of 132.67. The cuticle bears moderate hairiness, most pronounced on the ventral abdomen (9.494) and dorsal abdomen (6.734), while the dorsal head is almost bare (0.0). No sexual dimorphism is evident (score 0.0). The species is listed in the United Kingdom Species Inventory as present, though its establishment status remains indeterminate.
