Anderus maculifrons is a species of ground wētā (previously in the genus Hemiandrus Walker, 1869)[1] endemic to New Zealand.

[2] Being a nocturnal species, individuals remain in tunnels in the ground during the day and emerge from their burrows after sunset to forage and hunt for small invertebrates.

[7] The head is shiny and brown with a darker shade on top, showing a faint pale dorsal midline.

Ground weta are sexually sized dimorphic, with the females larger than males, unlike closely related species.

Adult males are characterised by the presence of bark, sclerotised hooks (falci) underneath the ninth abdominal tergite.

[7][11] These cryptic species are hosts to the intracellular bacteria Wolbachia, which might explain their speciation without ecological differentiation or geographic separation.

[7] They hide during the day in tunnels in the ground (galleries) under moss, soil, leaf litter and rotting logs.

[10] Galleries are cavities that can extent up to 10 cm below the surface of the soil or moss, and are usually slightly wider than the weta's body length.

[10] Anderus maculifrons are primarily predators and scavengers: they usually hunt and forage in forest litter and in trees at night.

Hemiandrus maculifrons has a non-seasonal life history: adults, young, and eggs can be found at any time of the year.

[15] Sexually active males hit their abdomens on substrates, such as leaf or soil surfaces, to produce pre-copulation vibratory sounds as signals for mate attraction; this is known as drumming.

[15] The nuptial gift is produced from a gland on the dorsal surface of the male's metanotum, in this case the spermatophylax, and females consume this while the sperms are transferred from the ampulla.
