Mesotarsus similar in shape to metatarsus, 2-segmented, first segment elongate, more than three times as long as wide at apex. Metafemur elongate, internal and lateral edges mostly parallel in ventral view, more than twice as long as wide, lacking distinct depressed area anterointernally before apex, apicoposterior edge unmodified, anterior surface with a well-defined sulcus on apical half. Metatibia moderately slender, slightly widening toward apex in anterior view, anterior surface with distinct row of setae, surface with irregular punctures and microsculpture, metatibial posterior surface convex between longitudinal row of setae and lateral edge, with transverse microsculpture. Metatarsus 2-segmented (Fig. 115), first segment elongate, more than three time as long as wide at apex, with anterointernal carina ill-defined. Abdominal sternites. Sternites 3–6 longitudinally slightly convex; sternites 4–6 with more than three unaligned row of setae laterally, glabrous medially; sternite 7 approximately longitudinally flat medially, shorter than segment 6 along midline; pygidium finely punctate on disc.
Measurements (2 males, 13 females). Length: male 12.0–13.5 (12.8±1.1), female 13.0–19.0 (14.3±1.6) mm.

Natural history. Unknown.
Remarks. Males differs in having the clypeofrontal carina higher, narrower and the pronotal anterior carina tuberculate medially. Parameres (Figs. 70–71) simply rounded apically in dorsal view and with minute raspy tubercles apically.
Variation is restricted to the extent of the metallic markings on head and pronotum as well as the development of the genal transverse carina.
Nomenclature and taxonomy. The primary citation for this species, as well as D. piceus, are illustrations that were preceding the publication of the text (Evenhuis, 1997). For Dendropaemon species, Perty used Eurysternus as the generic name which was subsequently corrected to Dendropaemon in the text. The original combination for both Perty’s name are those on the plates. The publication of the plate no. 8 has not been dated yet. We are here following Scherer (1983) for publication dates: 1830: pp.1–60, pls. 1–12; 1932: pp. 61–124, pls. 13–24; 1833: pp. 125–224, pls. 25–40.
1) Lectotype designation by Scherer (1983).
2) D. crenatostriatus Felsche, 1909 = D. viridis (Perty, 1830), new synonymy.
The holotype female of D. crenatostriatus Felsche, 1909 was compared to the lectotype of D. viridis (Perty, 1830) and both specimens are conspecific. Felsche (1909) compared his new species with D. viridipennis Laporte, 1831, from which it differ significantly instead of D. viridis which he confused with D. quadratus.
