Lathropatus nemorum

Females measure 1.02–1.25 mm in head width including eyes, while males are slightly smaller at 0.85–1.05 mm. The body is pigmented, with pigment insoluble in alcohol. Ground colour ranges from tan and brown to olive green or greyish-blue. Primary papillae are light-coloured basally and dark-tipped distally, and a mid-dorsal dark stripe may be present or absent. Dorsal papillae vary in size and distribution, forming semicircular or patch-like arrangements. Sexual dimorphism is evident in the number and arrangement of papillae, with females generally bearing a greater number per segment. Alternate plicae possess markedly enlarged primary papillae. The dorsum bears 12 complete plicae between oncopods, with wide and narrow folds alternating. Oncopods are cylindrical and uniform in size. Papillar scales are ribbed proximally and smooth distally. Tan or cream-coloured patches occur at the junction between the body and the feet. Ventral organs are white or cream, and newborn individuals lack pigmentation. Papillae surrounding the anal opening are pigmented similarly to the rest of the body. Spinous pads are pale yellow to tan and well developed on all oncopods. The antennae consist of approximately 30 rings, with wide and narrow rings alternating. Rings may be uniformly coloured or banded with tan pigmentation, and each ring bears a row of bristles. …

All type specimens were collected from decomposing logs in dry sclerophyll forest. Dominant vegetation includes Eucalyptus obliqua, E. baxteri, E. viminalis and E. willisii. Additional specimens were found in pine plantations, indicating tolerance of modified habitats where sufficient decomposing timber is available.

Males' gonopore is located between the last pair of oncopods. Crural glands and papillae are present on oncopods 2–14. The vasa efferentia are thin-walled and fuse to form the vas deferens. A spermatophore pouch is present. Females lack an ovipositor and are ovoviviparous. Ovarian tubes are suspended along the pericardial floor. Embryos develop within individual uteri at successive stages. Accessory glands are present, while a receptaculum ovorum is absent.

The generic name Lathropatus derives from the Greek lathrios ("secret" or "hidden") and peripatos ("walking"), the latter forming the basis of the name Onychophora and several related genera. While the specific epithet nemorum is derived from the Greek nemos, meaning "forest" or "wood", referring to the habitat in which the species occurs.
