2E5BF94E19643F7DFF679EB3AAC16DBE.taxon	discussion	Remarks. Arcangeli (1935), in his work on the isopods of Portugal, provides a detailed description of this species, offering diagnostic elements for its differentiation. Later, Vandel (1946), in his work on the isopods of the same country, considered it necessary to make four observations on Arcangeli’s description. The observations concerning the ornamentation of the dorsal integument (observation 3) and the anatomy of the left mandible (observation 4) are important because they contradict Arcangeli’s description and may complicate the identification of this species. This species was also illustrated by Reboleira et al. (2015), but they did not address the discrepancies between the descriptions provided by the two earlier authors. Therefore, we considered it useful to provide a new description of T. anophthalma and the other studied species, as well as to highlight the differences among the species of this genus in the Iberian-Balearic region.	en	Cifuentes, Julio, Bernabé, Iván Escarabajal-, Da Silva, Luís P.

2E5BF94E196A3F6BFF679E00AC816D9B.taxon	description	Description. Maximum length: 3.8 mm in females, 2.5 mm in males. Lacking pigmentation and ocular apparatus (Fig. 22 A – C). Integumentary characters (Figs 22 A – C, 23 A – D): Dorsal integument without granulations, with triangular scales and fan-shaped scale-setae of different sizes in irregular lines, five or six on cephalon, four on pereonite I, three on pereonites II to VII, and two on pleonites; one line on posterior margin. Noduli laterales near posterior margin, further from lateral margin, especially on pereonite V (Figs 6, 23 B). Somatic characters (Figs 22 A – C, 23 C – D): Cephalon inserted into pereonite I anterior concavity, lateral lobes continue pereon lateral margin; frontal line indistinct, vertex convex, merging with frontal area without separating line; large rectangular lateral lobes oriented laterally, large rounded middle lobe. Pereonites I and II with convex posterior corners, straight in pereonite III, with small angular projections on pereonites IV to VII. Large falciform neopleura continue pereon contour; posterior pleonite V corner shorter than posterior edge of uropod protopods. Triangular telson with straight sides and rounded tip, protruding beyond pleonite V corners. Appendages (Figs 24 A – E, 25 A – C): Mandibles with 1 + 1 free penicils, molar penicil dichotomised into three branches of increasing size. Maxillula inner endite with two penicils, outer endite with seven teeth. Maxilla and maxilliped as in Fig. 24 D, E. Antennula with three segments, second much shorter; third with six short aesthetascs. Short antennae, extending just beyond posterior edge of pereonite I; flagellum with two segments, second three times longer than first, with small aesthetasc group inserted approximately on last third. Uropod protopods much shorter than telson tip; endopod shorter than exopod, protruding little from telson tip. Sexual characters: Pereopods without sexual differentiation (Fig. 25 D). Male pleopod I (Figs 22 D, 26 A – B) with long curved endopod; subtrapezoidal exopod, wider than long with rounded internal and external sides. Male pleopod II (Figs 22 E, 26 C – D) with endopod longer than exopod, ending in thin tip; triangular exopod with long distal part with teeth on external edge and four long setae near the tip. Male pleopod exopods III to V as in Fig. 26 E – G, female exopods as in Fig. 26 H – L.	en	Cifuentes, Julio, Bernabé, Iván Escarabajal-, Da Silva, Luís P.
