Remarks

• Systematics: Subfamily Xanthophthalminae Ferris (Normark et al. 2025) urn:lsid:zoobank.org:act:C8C01741-C2D4-4867-BC76-2F8FBAF80F0B Austraspis is remarkable for having abdominal segments V and VI free (not fused), with only segments VII and VIII fused to form the pygidium, and in having a proliferation of multilobulate lobes (each with 3 to 6 lobules) on the abdomen. The proliferation of multilobulate lobes seen in Austraspis is unique and should permit separation from all other genera. But to date, Austraspis species have been misidentified in collections. (Normark et al. 2025) Austraspis resembles Lopholeucaspis in having multisetose antennae, a row of duct tubercles on the ventral submargin of the cephalothorax, 5-locular pores near the anterior spiracles, and small 2-barred ducts. But Austraspis differs from Lopholeucaspis in having multilobulate lobes (all lobes unilobulate in Lopholeucaspis) and pores by the posterior spiracle (absent in Lopholeucaspis), in lacking plates and perivulvar pores (both present in Lopholeucaspis), and in being only partially enclosed within the exuviae of the second instar (Lopholeucaspis fully enclosed within a puparium). (Normark et al. 2025)
• Structure: Occurring on the leaves or bark of the host; adult female partially enclosed within second-instar exuviae; first exuviae retained at anterior margin of second exuviae. Slide-mounted adult female without gland spines; without regularly arranged plates (though a few unsclerotized lobules may appear plate-like); with all 8 abdominal segments free, or with abdominal segments VII and VIII apparently fused; dorsal ducts 2-barred, minute; antenna with multiple setae; quinquelocular pores present near anterior and posterior spiracles; sclerotized lobes (trullae) always bilobulate or multilobulate, never unilobulate; lobe present on each on each of abdominal segments VI–VIII, present or absent on each of segments II–V; ventral submargin of cephalothorax with row of gland tubercles. (Normark et al. 2025)
• Biology: Occurring on the leaves or bark of the host; adult female partially enclosed within second-instar exuviae; first exuviae retained at anterior margin of second exuviae. (Normark et al. 2025)
