Description. – Small (body length <50.0 mm) and moderately slender Obrimini with distinctive body armature, a prominent spiniform posteromedian protrusion on abdominal terga III-V and slender, distinctly spinose-dentate limbs. General body shape fairly elongate and almost uniform (♂, Fig. 5 A-C) to sub-uniform (♀, Fig. 4 A-C) in diameter. Body surface densely but unevenly granular to tubercular. Colour dark brown with elements of armature contrasting yellow to orange. Head notably longer than wide, sub-cylindrical with vertex flattened and just slightly raised at posterior margin; only the four coronals distinct. Antennae of moderate length and reaching to metanotum. Pronotum with a strong pair of pre-medial spines just in front of transverse median sulcus ( Fig. 6A, D). Mesothorax almost parallel-sided and rectangular in outline and> 2.5x longer than prothorax. Posterior meso- and metanotals developed but small and obtusely spiniform ( Fig. 6 A-B, D-E). Meso- and metapleurae with obtuse tubercles; meso- and metapleural spine small and rather tubercular. Meso- and metasternum with distinct tubercles and very weakly bulgy medio-longitudinally. Abdominal segments transverse in ♀ and subquadrate in ♂; basal four segment somewhat inflated in ♀; II-II uniform in width in ♂. Terga III-V with a prominent, spiniform posteromedian protrusion ( Fig. 4F), which is bi-fid in ♀; terga VIII and IX with an obtusely dentiform posteromedian swelling. Ovipositor weakly up-curved ( Fig. 4J) with epiproct obtuse apically and subgenital plate acutely pointed and projecting beyond epiproct. Praeopercular organ on sternum VII a rounded median pit some distance in front of posterior margin ( Fig. 4H). Poculum in ♂ bulgy, angular ( Fig. 5H) and notched posteromedially ( Fig. 5G). Vomer slender, basically triangular in shape with a long and gently curved terminal hook ( Fig. 72G). Legs long, slender and will all carinae except for the ventral carinae of the smooth pro- and mesotibiae armed; dorsal carinae of femora dentate, ventral carinae rather spinose and dorsal carinae of tibiae very obtusely dentate to lobate. Flexure of profemora moderate. Medioventral carina of femora indistinct. Tarsi short and slightly less than half as long as corresponding tibiae.

Egg. – Of average size (length 5.2-5.5 mm), elongate, sub-circular in diameter and capsule about 2.3x longer than wide. Entire surface of capsule and micropylar plate densely pitted. Micropylar plate large and almost as long as capsule; anterior end broad and roundly angular, the two posterolateral extensions narrowed and reaching to polar end. Median line distinct and reaching to polar area. Operculum slightly elliptical, flattened and with an elliptic mount of setae in centre.Colour uniformly brownish dark grey.

Differentiation. – This remarkably and distinctive small new genus is closest to Eubulides , which it shares the flattened and subcylindrical head, which is just weakly raised at the posterior margin, anterior spines of the mesonotum and just slightly sub-parallel mesothorax of both sexes, as well as the characteristic praeopercular organ of ♀ that is formed by a rounded pit some distance in front of the posterior margin of abdominal sternum VII. Armadolides n. gen. however readily differs from Eubulides by the generally much more pronounced elements of the thoracic and abdominal armature, which includesa large pre-median pair of spines just in frontof the transverse median sulcus of the pronotum ( Fig. 6A, D), developed posterior meso- and metanotals ( Fig. 6 A-B, D-E), as well as a distinctive and large spiniform posteromedian protrusion on abdominal terga III-V ( Fig. 4F). The latter character also separates this new genus from all other members of the whole of Obrimini .The eggs are very similar to those of Eubulides and merely differ by the relatively longer micropylar plate, which is almost as long as the capsule with the anterior end almost reaching to the anterior margin of the capsule.

Etymology. – The generic name is a combination of the Filipino “ armado ” (= armed, spiny) and the ending - lides of the closely related Eubulides Stål, 1875 to emphasize on the distinctive body armature and close relation to that genus. It is intended to mean “Spiny Eubulides ”. Neuter.

Remarks. – The eggs are not known.

Distribution. – Mindanao
