Abstract: Alt Text: Composite photograph of the Minuca victoriana fiddler crab which includes several black & white images of different views of the crab, a color photograph, and a distribution map. Composite Image Description: Figure 23. Minuca victoriana (von Hagen, 1987). UNI 168. Collected: 9 July 2009, Brazil, Espirito Santo, Vitoria, Bairro Joana D’arc mangroves (-20.283984, -40.305919). Scale Bar = 10mm. (A) Dorsal view. (B) Front view. (C) Inner cheliped. (D) Ocular view. (E) Ambulatory. (F) Color Photo. (G) Distribution Map (Finke 2024). Species Description: Moderate sized (width < 15 mm). Carapace length 59% of width (Fig. 23A). Frontal region 33% carapace width. Eyestalks short. Surface of carapace smooth, shiny and finely granular. H-depression deep with pubescence in lateral sulcus. Carapace surface irregular near anterolateral margin. Anterolateral angles pointing outward (Fig. 23A). Intersection of lateral and posterolateral margins form sharp obtuse angle. On major cheliped, dorsal surface with ridge (Fig. 23A). Moderate-size tubercles decreasing in size toward ventral manus (Fig. 23B). A triangular depression with pubescence dorsal to origin of pollex (Fig. 23B). Dactyl and pollex blade-like, gap large (Fig. 23B, C). Dactyl articulation without tubercles. Pollex with one large tubercle in gap. Gap wide. Dactyl with several larger tubercles proximal to articulation in gap with a single large distal tubercle. On inner surface, dorsal carina of carpal cavity with elongate tubercles, terminus trifurcated (Fig. 23C). Carina extends around distal cavity margin to prominent tubercles at proximal end of oblique ridge. Structure sharply defined with clearly separate tubercles. Pre-dactyl tubercle ridge parallel to dactyl articulation. Tubercles on dactyl articulation fused. Dorsal surface of carpus in cavity with no large teeth. Merus width of ambulatory legs 1–3 about 29% length (Fig. 23E). Dorsal merus and carpus with pubescence and long setae. No setae or pubescence on ventral merus of ambulatory legs. Endemic to the coast of Brazil from Fortaleza, Ceará to Bertioga, São Paulo (Fig. 23 G).
