Remarks
The species was originally described by Delamare-Debouteville [46] from some caves in Portugal (Algar do Pinheiro, Algarve do Cabeço Redondo, and Gruta das Alcobertas). Later, it was recorded from two caves in Tenerife (Canary Islands)—Cueva del Yeso o de las Goteras and Cueva Grande de Chío [47]—and two caves in Almería—Cueva de la Corraliza and Cueva Simarrón II [48]. Regarding posterior references, some of them without official publication (including some of the specimens studied here) have been registered in a data paper [49].
The principal features of the species, shared with the studied specimens, are as follows: antennae shorter than body length; Ant IV without apical bulb; no eyes; labral papillae as rounded projections; lateral process of labial papilla E just exceeding (or slightly) the apex of papilla; basal labial row with chaeta r vestigial, and l 2 smooth; tenent hairs clavate; unguis with four teeth: I–III basal teeth unequal; medial tooth not surpassing the unguis apex; unguiculus pe lamella serrated (in the original description is drawing smooth); dens with 12–16 inner spines in one row; and mucro in total with 5–6 teeth (2–3 basal and three distal). Only two species have enough similarity to be compared with them: T. canis Christiansen, 1957, from Lebanon (with a smaller mucro, 5–6 basal and 2 distal teeth on mucro), and T. laticlavatus Stach, 1960, from Afghanistan (with only three teeth on inner unguis, tenent hair pointed, two distal teeth on mucro, and unguiculus not serrated and with one tooth).
Some characters observed in the specimens from the caves of Almería studied are presented in Figure 7: dentes (Figure 7A), ventral tube (Figure 7B), mucro (Figure 7C), and unguis (Figure 7D,E).
