Description. Uniformly dark brown. Antennal clubs with apical 2 segments white, basal segment grey.

Total length: 2.7–3.2 mm. Holotype measurements: total length 3.0 mm, elytral width 2.0 mm.

Male. Head. Surface with fine punctation, short basal carina present only adjacent to eyes. Clypeal edge normal, without projection lateral to teeth. Genal angle weakly defined. Dorsal part of the eyes narrow, separated by an interocular space approximately 21–22 times the eye width (43:2). Head 1.4 x wider than long (57:40).

Prothorax: Pronotal surface with light punctation. Anterior angles obtuse and blunt. Basal angles rounded and obtuse. Punctures along the basal margin absent. Pronotum 1.55 x wider than long (47:30).

Elytra: Surface smooth with superficial striae; intervals finely punctate. Striae 6 and 7 extending to elytral base. Elytra 1.5 x wider than long (60:40)

Legs: Protibiae with 2 teeth on outer edge, front edge deeply angulate. Apical digit long and parallel sided with a rounded apex with a very small comb of stout setae, and bearing a short spur on the outer apical angle. Metatibiae with a notch on the inner edge.

Abdomen: Pygidium simple, smooth, often finely reticulate basally, finely punctate and slightly convex. Abdominal ventrites reticulate right across.

Pterothorax: Medial lobe of metaventrite very finely punctate and margin between the mesocoxae virtually absent. Lateral lobe of metaventrite finely punctate, with inner border beside mesocoxae anteriorly straight, lateral border virtually absent. Mesoventrite notched anteriorly. Mesoventrite smooth. Metanepisternum reticulate.

Aedeagus: Small tufts of setae projecting from apices of both right and left parameres, left paramere somewhat spatulate.

Female. Metatibiae without a notch on the inner edge. Three stout setae on apical digit of protibiae in the same plane. Otherwise as per L. monteithi   species group.

Distribution. Known from the rainforests of the Iron Range area from Mount Tozer east through the valleys of the West and East Claudie Rivers to as far east as Gordons Creek within the Cape York Peninsula bioregion ( Fig. 12A View FIGURE 12 ). This species appears to be a short range endemic and has only been collected within a 30 km diameter area.

Comments. The majority of specimens have been collected in pan traps, berlesed litter and in pitfall traps baited with human faeces. This species appears to be a generalist as it has also been collected in pitfall traps baited with mushroom, banana, and dung.

Matthews (1974) mistakenly described the species as having 3 protibial teeth but the holotype (QM T7104) has only 2 tibial teeth (see Fig. 8I View FIGURE 8 ). Matthews’ species concept of L. monteithi   was derived from examining a combina- tion of specimens of L. monteithi   and L. geoffi   new species as some of the paratype series of L. monteithi   are L. geoffi   . These species are not only superficially similar but also occur in the same area. They can be distinguished from each other by number of protibial teeth, presence/absence of a setose pit on the metaventrite, and shape and setation of the male genitalia. The outline of the protibia and parameres illustrated for L. monteithi   (see Figs 184, 300–301 of Matthews (1974)) match more closely L. geoffi   (see Fig. 10A View FIGURE 10 ). We ignore the written the description and illustrations of L. monteithi in Matthews (1974: 108)   and rely solely on the holotype to ground our species concept and redescription of L. monteithi   . Sequences have been generated from multiple specimens including from East Claudie River (25- 060814, 25- 060816 –17, 25- 060819), Gordons Creek (25- 060820), and Lamond Hill (25- 060815) and show minimal sequence variation but are distinct from all other species in the L. monteithi   species group. The phylogeny of Gunter et al. 2019 included all five species in the species group with L. monteithi   forming a sister relationship with L. reidi   .
