03D4FB44CA4C4D19159F7DBAFC8D9578.taxon	diagnosis	Diagnosis. Differentiated from other species of the genus by the combination of the orange opisthosoma lacking any longitudinal stripes as well as dark lateral patterns in combination with a less coiled embolus compared to M. vatia. In M. vatia, the embolus is much more strongly coiled, with the distal part nearly in parallel position to the sides of the cymbium and the tip at a 90 ° angle (Figs 1 B 1, B 2, B 4 )), while in M. bicolor the distal part and the tip point, more or less, in the same direction (Figs 1 A 1, A 2, A 5). In addition, the RTA of M. vatia bears an additional hump in the basal part (Fig 1 B 3), which is missing in M. bicolor. The position of the spermophor in the basal part of the embolus differs as well. While the spermophor is positioned more horizontally in M. vatia, in M. bicolor it enters the embolus in a transversal position.	en	Bach, Alexander, Lauterbach, Stephan, Astrin, Jonas J., Thorns, Hans-Jürgen, Bauer, Tobias (2024): A master in disguise?

03D4FB44CA4C4D19159F7DBAFC8D9578.taxon	description	Description. Male (from Sardinia, in ethanol): Pr length 1.3, Pr width 1.35, Op length 1.9, Op width 1.35. The prosoma of M. bicolor is black in live specimens, with a lighter area behind the fovea and the eyes. When preserved in ethanol, the prosoma becomes dark reddish-brown. In contrast, the prosoma of M. vatia features a light, often yellow, longitudinal stripe. The opisthosoma of M. bicolor is a light yellowish tone, covered with conspicuous, short spines, and lacks any longitudinal lines or dark lateral patterns, which sharply contrasts with the opisthosoma of M. vatia. The femora of the first pair of legs are prominently dark in color, while the remaining segments display an anterior reddish-brown hue, with a gradual brightening towards the posterior regions Left leg measurements: I. coxa 0.40; trochanter 0.30; femur 2.10; patella 0.70; tibia 1.75; metatarsus 1.50; tarsus 0.50; total length 7.25 II. 0.40; 0.25; 2.05; 0.65; 1.70; 1.45; 0.80; 7.30; III. 0.30; 0.15; 0.90; 0.40; 0.70; 0.55; 0.40; 3.40; IV. 0.35; 0.20; 0.90; 0.40; 0.70; 0.60; 0.40; 3.55.

03D4FB44CA4C4D19159F7DBAFC8D9578.taxon	discussion	Comment. Our specimens (Figs 2 A – B, 3) are consistent with the somatic description provided by Simon (1875). However, concerning the palp, Simon’s description merely notes that it is disc-shaped and of a reddish coloration. Similarly, Lehtinen’s (2004) description is relatively concise, mentioning only the differences between M. bicolor and M. vatia with respect to a stronger coiled embolus and details in RTA morphology. However, Breitling et al. (2016) highlighted the important difference that the embolus in M. bicolor is less coiled than in M. vatia, a characteristic which was also observed in both of our specimens (Fig. 1 A 5). Molecular analyses. In the Neighbor Joining tree (Fig. 5), the COI sequence of the Misumena bicolor male from Germany clearly falls outside the M. vatia cluster. The genetic distances between M. bicolor and M. vatia range from 6.4 to 8.0 % (uncorrected p - distance when comparing full sequences of M. vatia in the dataset, over a length of 653 bp). Intraspecific distances in M. vatia range from 0.0 to 2.3 %. This provides strong evidence in favor of allocating the specimens from Germany (and Corsica) to a species distinct from M. vatia. A single sequence of a potentially juvenile “ M. vatia ” - specimen from Corsica on BOLD (Process ID LPRCS 004 - 19) is nearly identical to our sequence and represents M. bicolor (BIN / Barcode Index Number BOLD: AEC 4584) as well. Genetic distance of the M. bicolor specimens to the outgroup Spiracme striatipes is ca. 12 % (same for M. vatia) and to Misumena spinifera ca. 9 %. Misumena vatia is separated from M. spinifera by around 10 %. Photographic records from naturalist networks. In addition to the two photo-based records from Germany in Breitling et al. (2016), fourteen other photo-records from Germany, mainland France, Italy and Austria were identified. Links and coordinates from all sites are given in the supplement table. Photographic evidence of M. bicolor in mainland Europe is available from west or north of the Alps. The westernmost photographic record comes from the French commune Astaffort in the department of Aquitaine, while the northernmost locality is in the Solling, a German low mountain range in Lower Saxony (Fig. 6).	en	Bach, Alexander, Lauterbach, Stephan, Astrin, Jonas J., Thorns, Hans-Jürgen, Bauer, Tobias (2024): A master in disguise?
