Diagnosis: The male of this species is distinctive among Australian Agapetus species due to the presence of a stout, black mesal ridge on each gonopod, easily visible in ventral aspect, and due to prominent black spiny apices on the lobes of segment X. Agapetus neboissi sp. nov. has similar apices on segment X. However, A. neboissi has a prominent sclerotised spur on each gonopod in the position of the gonopod ridge of A. christineae and A. neboissi has abdominal segment IX triangulate.

Forewing length: Male 4.3–4.6 mm; female 4.1–4.8 mm.

Male genitalia: Sternum VI mesal process present, well developed, apically slightly rounded, projecting caudad. Tergum X forming 2 unequal lobes, each with an attenuate, darkly sclerotised, upturned apex. Cerci almost half as long as gonopods, stout, rounded apically, each with row of setae dorsally. Gonopods well separated medially in ventral view and each with a sclerotised, broad, bladelike process on mesal margin; in lateral view stout, length more than 2X height, apically rounded. Phallic apparatus simple, rod-shaped, without spines or parameres.

Female: Terminalia very narrow when viewed from ventral aspect ( Fig. 21 View FIGURES 21 – 23 ). Sternum VI mesal process present, darkly sclerotised; segment VIII well developed, very darkly sclerotised and deeply but narrowly excised mid-ventrally.

Etymology: Named for Christine Lambkin, who, together with Noel Starick, collected the material in post-2003 fire surveys in Kosciuszko National Park.

Distribution: Known only from the Australian Alps of southern New South Wales and northeastern Victoria.
