Speonomus mercedesi Zariquiey, 1922: 161 Type locality. “Bofia de S. Jaume” ( Zariquiey 1922a ). Differential diagnosis. Bathyscioid species of Troglocharinus with well-developed mesoventral keel, vertex hook-like; first male protarsomere slightly wider than apex of tibia, as long as 2nd–3rd together, heart-shaped. elon-gated. Median lobe of aedeagus regularly curved in lateral view, apex elongated and weakly sinuate. Endophallus with thin, long and narrow NCs, base wider than apex; upper node of the FVM with a notch and oriented towards apex; PF2 very wide. Spiculum of the female urite viii very short and narrow. Description of the species. Body length 2.9–3.0 mm. Body shape oval. Body surface finely punctated on pronotum, with transverse striolas on elytra. With fine, yellowish, recumbent conspicuous pubescence. Antennomere length as in Table 3 . Pronotum transverse, lateral margins regularly arched, slightly narrower than elytra, with maximum width at base (maximum width = 1.4 x length = 0.9 mm.). Elytra elongated, regularly tapering towards apex, maximum width on anterior third. Mesoventral keel well developed, with hook-like vertex. Legs very long and slender, in particular the posterior legs. Mesotibia weakly arched, first protrarsomere ( Fig. 10 ) slightly wider than apex of tibiae, as long as 2nd–3rd tarsomeres together, heart-shaped, elongated. Median lobe of aedeagus with subparallel margins in dorsal view ( Fig. 23 ), with apex apparently truncated; regularly curved in lateral view ( Fig. 18 ); apex elongated, sinuous and pointed. Lateral stylus of the tegmen sinuate, somewhat shorter than median lobe and with three long, curved setae on apex, two inserted laterally; third noticeably shorter, thinner, straight and inserted on the opposed side. Membranous lamina very long, with a long and dense tuff of setae (“penicillum”) inserted in the apical region, including the membranous lamina. Intersal sac of the aedeagus ( Figs 33, 34 ) with narrow elongated NCs, with base wider than apex; NFVM elongated, apex bifurcated, with the larger branch orientated towards apical region; PF2 very wide. Female. Elytra markedly convex, wider than pronotum. Protarsi not dilated, filiform. Spiculum of the urite viii short and narrow ( Fig. 61 ). Spermatheca thin and very long, median part elongated; with lobes slightly bend with respect to the median region, basal lobe thicker than median region, apical lobe hemispherical ( Fig. 50 ). Spermaduct very long, 70–80 times longer than spermatheca. Comparative notes. See Comparative notes of T. mengeli above for differences between the two species. Distribution ( Fig. 71 ). 1.
