Designated here.</p><p>Etymology.</p><p>The genus-group name honours the Swedish pop group ABBA whose songs and subsequent musicals Mamma Mia! (2008) and Mamma Mia - Here We Go again! (2018), provided hours of entertainment for the authors. The gender of the genus-group name is feminine.</p><p>Diagnosis.</p><p>Abba gen. nov. can be diagnosed by the set of strong prolateral macrosetae on the first tibia of the males and by the distinct colouration of the abdomen in both the males and females, consisting of a pair of dark spots centrally on a uniformly creamy-white to grey dorsal surface (Figs 1A, 3, 4A).</p><p>Description.</p><p>Small orb-weaving spiders, males (total length ca. 3.0-3.5) smaller than females (total length ca. 4.0-4.5). Carapace longer than wide, pear-shaped and with cephalic region comparatively narrower in males than in females; colouration yellowish-brown (green in live specimens), generally without setae (Figs 1A, 4A). Fovea transverse in males and females. Anterior median eyes largest, row of posterior eyes slightly recurved, lateral eyes almost touching; lateral eyes on joint tubercles but the row of the posterior lateral eyes slightly wider than that of the anterior lateral eyes; anterior median eyes slightly protruding from the carapace (Figs 1A, 4A). Maxillae subquadrate, yellow with anterior dark border (Figs 1B, 4B). Sternum longer than wide, yellow, with a sparse cover of setae (Figs 1B, 4B). Labium wider than long, with anterior glabrous light edge (Figs 1B, 4B). Chelicerae fangs with three promarginal teeth of similar size, and three retromarginal teeth of similar size. Legs: Leg formula I&gt; IV&gt; II&gt; III; males with set of ca. five strong prolateral macrosetae on the first tibia (Figs 1A, 3). Abdomen slightly longer than wide, somewhat dorso-ventrally compressed, oval, without humeral humps, specialized setae, sigilla, condyles or other specific structures; colour dorsally varying from beige to grey, bearing two centrally located dark spots (Figs 1A, 4A). Venter grey, sparse layer of guanine crystals (Figs 1B, 4B).</p><p>Male pedipalp patella with two macrosetae (Fig. 1C, D); paracymbium elongated and hook-like (Figs 1D, 2B); median apophysis subquadrate spatulate, with strong sclerotized finger-like tip and sclerotized base (Figs 1C, 2A, B); radix poorly developed (Figs 1C, 2A); terminal apophysis wider than long, rounded with sclerotized tip (Figs 1C, D, 2A, B); conductor elongate, membranous, apically slightly curved (Figs 1C, D, 2A, B); embolus heavily sclerotized and thick, curved basally, uncapped (Figs 1C, D, 2A, B).</p><p>Epigyne base rounded, lateral portion rounded and heavily sclerotized; atrium wide and heavily sclerotized with copulatory openings located posteriorly (Fig. 4C, D); scape approximately as long as atrium length, not exceeding posterior epigyne base, with terminal pocket (Fig. 4C); spermathecae ovoid to spherical, larger than atrium (Fig. 4C-E).</p></div>	https://treatment.plazi.org/id/CBDDC243A74E51D4BE13B3704058359E	Public Domain	No known copyright restrictions apply.

Labium 0.14 long, 0.25 wide, subtriangular and yellow, maxillae yellow (Fig. 1B). Sternum 0.6 long, 0.5 wide, yellow with sparse setae (Fig. 1B).

Abdomen 1.9 long, 1.5 wide, dorsum grey, with scattered, small white spots, and a pair of median large dark spots (Fig. 1A); laterally off-white; venter grey centrally covered by guanine crystals (Fig. 1B). Pedipalp (Figs 1C, D, 2A, B): length of segments (femur + patella + tibia + cymbium = total length): 0.3 + 0.2 + 0.1 + 0.3 = 0.9; description as for genus.</p><p>Female (based on QM S8810): Total length 4.2.

Chelicerae of similar colour and dentition as male (Fig. 4B). Legs of similar colour as male, covered with thin setae (Fig. 4A, B). Pedipalp: length of segments (femur + patella + tibia + tarsus = total length): 0.3 + 0.1 + 0.2 + 0.5 = 1.1. Leg formula I&gt; IV&gt; II&gt; III; length of segments (femur + patella + tibia + metatarsus + tarsus = total length): I - 1.1 + 0.5 + 1.1 + 1.0 + 0.5 = 4.2, II - 1.0 + 0.4 + 1.0 + 1.0 + 0.4 = 3.8, III - 0.6 + 0.3 + 0.4 + 0.4 + 0.3 = 2.0, IV - 1.0 + 0.4 + 1.0 + 0.9 + 0.6 = 3.9.

Abdomen 2.6 long, 2.2 wide, dorsum off-white with a pair of two median dark spots proportionally smaller than in male (Fig. 4A); lateral and ventral parts similar to those of male (Fig. 4B). Epigyne (Fig. 4C-E) same as for genus.</p><p>Variation.</p><p>Males (total length 3.0-3.3, n = 4). Live images of Abba transversa comb. nov. have been published online (e.g., http://www.findaspider.org.au/find/spiders/131.htm; accessed 30 October 2022). The cephalothorax, legs and ventral abdomen are green in live specimens, and the eye region is somewhat yellowish.</p><p>Remarks.</p><p>Davies and Gallon (1986, p. 233) in a catalog of type specimens of the Queensland Museum firstly realized that the female syntype of Araneus transversus is in fact Gea theridioides and somewhat cryptically proposed a new synonymy ("#f = Gea theridioides (L. Koch) n. syn. - V.T.D"). This taxonomic act, however, was not accompanied by the necessary designation of the female as a lectotype. Later cataloguers apparently did not accept this synonymy, and A. transversus is still listed as valid species (World Spider Catalog 2022). We here designate the male syntype as the lectotype of A. transversus to fix the species-group name of the species and thereby reject Davies and Gallon’s (1986) synonymy.</p><p>Life history and habitat preferences.</p><p>At the Proserpine River, Queensland, Abba transversa comb. nov. was found sweeping foliage and grass in an open forest (Rainbow 1916). A single label in the material examined read "coastal ironbark". Mature males and females were generally collected from November to January, except for a male, female and juvenile collected between June and July. The species appears to be largely summer-mature.</p><p>Distribution.</p><p>We examined museum material from northern to south-eastern Queensland and southern New South Wales (Fig. 5). There are records from Victoria on iNaturalist (https://www.inaturalist.org/taxa/533368-Araneus-transversus; accessed 22 July 2022) that may represent this species, but without examination of genitalia an identification cannot be ascertained; these records may represent a second congeneric species.</p></div>	https://treatment.plazi.org/id/9D66F4C2999C5905B653BE5866B5D03C	Public Domain	No known copyright restrictions apply.
