Description.

Setation of mandibles: present. Setation of clypeal area: dense. Shape of clypeus: truncate. Anterior tentorial pits: large. Facial and malar striae: present, dorsal striations not confluent with concentric sculpture of antennal scrobe. Central keel: absent. Setation of interantennal area: surpassing dorsal margin of toruli. Sculpture of frons: reticulate throughout, weakly reticulate medially, punctation absent dorsally. Position of lateral ocellus: less than 1 OD from inner margin of compound eye. Interocular space: 1.25 × length of compound eye. Occiput directly anterior to anteromedial portion of occipital carina: smooth to reticulate. Sculpture of occiput: densely reticulate; reticulate. Color of antennomeres: yellow-brown; concolorous with legs. Number of papillary sensilla on A6: 1. Number of papillary sensilla on A7: 2. Glabrous patch on lateral propodeal area adjacent to spiracle: absent. Shape of mesoscutellum in lateral view: convex. Shape of transepisternal line: arched. Shape of mesoscutellum in dorsal view: oval, 2 × wider than long. Sculpture of posterior mesoscutellar sulcus: laterally striate, smooth medially. Posterior mesoscutellar sulcus: incomplete medially. Setation of mesoscutum: present. Setation of mesoscutellum: present throughout. Path of notauli: subparallel. Shape of notauli: same width throughout. Setation of anteromedial T2: contiguous. Number of setae on lateral surface of T3: 2; 3. Number of setae on lateral surface of T4: 4. Number of setae on lateral surface of T5: 6. Felt field on S2: approximately as long as lt2. Setation of laterotergites: present on lt2. Setation of dorsal surface of hind coxa: sparse. Color of coxae: brown; concolorous with mesosoma.

Diagnosis.

Alfredella tasmanica differs from its congeners by the abbreviated, parallel notauli, incomplete posterior mesoscutellar sulcus, and nearly truncate ventral clypeal margin.

Distribution.

Australian Capital Territory, South Australia, Tasmania.

Inhabited ecoregions

(bioregions). Deserts and Xeric Shrublands (Flinders Lofty Block); Temperate Broadleaf and Mixed Forests (Kanmantoo, Ben Lomond, Tasmanian Southern Ranges).

Material examined.

Holotype, female: Australia: Tasmania, Mt. Field N.P., Jan. 8-14, 1984, L. Masner, MT, ANIC Database No. 32 153909 (deposited in ANIC) . Paratypes: Australia: 3 females, 1 male, OSUC 697975-697978 (CNCI) . Other material: Australia: 5 females, OSUC 697979-697983 (CNCI) .

Comments.

The distribution of this species is expanded to include the Fleurieu Peninsula and Waite Arboretum of South Australia and Black Mountain of Australian Capital Territory. Alfredella tasmanica likely has a wide distribution across southern Australia, and its absence from Victoria is probably due to a lack of collecting in that region.
