Tisamenus tagalog (Rehn & Rehn, 1939) (Fig. 43) Hoploclonia tagalog Rehn & Rehn, 1939: 480, pl. 32: 17 (♂). HT, ♂: Aroroy, Masbate Island, P.I.; (W. Boettcher) Aug. 8,1912; Hoploclonia tagalog Rehn & Rehn, Type #.1347; Data Base Serial No. Assigned as Type No. September 2008. Type #9129 [ANSP]. - Otte, 1978: 79. (Type data) Tisamenus tagalog, Zompro, 2004: 207. - Otte & Brock, 2005: 335. - Brock & Büscher, 2022: 522. - Hennemann, 2023b: 128. Differentiation. – This species is only known from the unique ♂ holotype in the collection of ANSP (Fig. 43) and morphologically very close to T. armadillo Redtenbacher, 1906. Effectively, the only differences seen versus the ♂ of armadillo are the somewhat larger bifid anterior pronotal spines and supra-coxals of the meso- and metapleurae, more spinose supra-orbital, slightly convex and minutely tubercular carinae of the triangular mesonotalarea that have the anterior angle just weakly protruded (rather concave with the anterior angle triangularly raised in armadillo), smaller epiproct that scarcely extends beyond the posterolateral angles of the anal segment, flattened and scoop-shaped poculum (deeply angular and bulgy in armadillo) and more prominent spines of the posterodorsal carina of the metafemora. Remarks. – More specimens, including the still unknown ♀ and egg are required for a better distinction from closely related species but T. armadillo in particular. Body length ♂ 37.8 mm. Distribution. – Masbate. Province Masbate (Aroroy [ANSP – type locality]).
