Lanurgus podocarpi Schedl, 1955  

( Figs 3, 6, 9, 10 View FIGURES 2–12 , 68, 69 View FIGURES 66–71 )

Traglostus brevisetosus Schedl, 1957   (syn. by Beaver 2011)

Lanurgus bicolor Schedl, 1961   (syn. by Beaver 2011)

Pseudohylocurus caplandicus Nunberg, 1961   (syn. by Beaver 2011)

Type material. Syntypes: Kenya, Londiani [ NHMUK]. Male holotype of L. brevisetosus     : South Africa, Kokstad, Griqland E, Mar 1926, Forester [ NHMW]   . Paratype of L. bicolor   : South Africa, Tonti [south of Kokstad ], JH Grobler, 5.1.1959 [ NHMW]   .

Diagnosis, female. Length 2.1–2.7 mm, 2.0–2.2 × as long as wide; frons lightly concave, densely covered by short, erect, fine setae; scapus with a dorsal triangular extension bearing a tuft of setae shorter than eye length; first segment of antennal club corneous, glabrous; eyes separated above by 3.2–3.4 × their width; pronotum 1.1 × as long as wide; scutellum with narrow scale-like setae; elytral interstriae 1–10 with broadly confused, erect, bristle-like setae; protibiae with four apical denticles. Male similar to female except scapus only slightly thicker than pedicel, with few setae, and the frons is transversely and lightly impressed just above the epistoma with scant setae and rough granules above.

This species is similar to L. oleae   and L. xylographus   but has all interstriae densely covered by erect setae.

Distribution. South Africa, Tanzania, Kenya.

New records. South Africa, Western Cape: Knysna, Goudveld, Jubilee creek [GIS: -33.890, 22.964], B. Jordal, leg., 4.xi.2006 #4, ex Podocarpus falcatus   ; Knysna, Goudveld, Krisjan Se-Nek [GIS: -33.913, 22.948], B. Jordal, leg., 5.xi.2006 #9, ex Podocarpus falcatus   ; Wilderness, Ebbe Flow [GIS: -33.980, 22.613], B. Jordal, leg., 2.xi.2006 #1, ex Podocarpus falcatus   . Eastern Cape: Bloukrans, Rugbos Forest [GIS: -33.96, 23.67], B. Jordal, leg., 12.xi.2006 #2, ex Podocarpus falcatus  

Biology. Breeds under bark of 8–15 cm thick branches of yellowwood, Podocarpus falcatus   ( Podocarpaceae   ). A male establishes a mating niche and allows one, or more commonly, two females to join. The two females excavate egg tunnels in a u-shaped gallery formation following mainly the longitudinal direction of the bark and phloem. Larvae chew tunnels mainly across wood fibres. The total brood size per family was 42 and 66 (n=2). Males and females leave before or die at the pupation stage.
