Coraebosoma viridis , sp. nov.

( Figs. 3, 6 )

Description (3 holotype). Elongate-ovoid, subcylindrical, flattened above and below, yet feebly transversely convex; maximum length from head to elytral apex: 17.5 mm; maximum width: 6.8 mm, widest at about posterior 1/3 of pronotal length and subequal opposite elytral humeri, L/W (length/width) 2.57; integument of head, pronotum, ventral surface and legs green-aeneous, elytra green with a faint aeneous reflection along anterior margin and on disc medially; entire integument sparsely covered with small, well-separated punctures, each with a single very short, semi-erect seta; frontovertex median depression dorsal to antennal insertions, moderately clothed with recumbent setae; pronotal and elytral discs with no concentrations of setae either in circular patches or fasciae; anterolateral explanate areas of pronotum moderately covered with short recurved setae; ventral surface vestiture: lateral portion of hypomeron, lateral 1/2 of metacoxal plate, at apicolateral angles of abdominal ventrites 1–4; a fringe on ventrites 3–5 moderately covered with recumbent off-white setae; small area on abdominal ventrite 1 feebly depressed, setae slightly more concentrated, apparently to cushion dorsal surface of respective femora; pronotum 1.8 x wide as long; lateral portion of each elytron feebly transversely rugose; lateral margins of elytra subparallel to before apical 1/3; anteromedial portion of pronotal disc strongly convex; elytral apicolateral margins slightly more serrate at separately angulate apices; inner tooth of bifid claw subequal to outer tooth. Male genitalia as in Fig. 6 .

Variation. There is no obvious sexual dichromatism or dimorphism. Color in the type series varies from the holotype by having the same, or nearly so, elytral color also on the head and pronotum, although most of the specimens are closer in color to the holotype. The type series varies in size as follows: 33 (n = 15), length 17.5–20.8 mm, width 6.5–7.7 mm, ƤƤ (n = 5), length 18.5–20.5 mm, width 6.9–7.2 mm and unsexed (n = 3), length 17.7–21.0 mm, width 6.3–7.3 mm.

Specimens examined. Holotype, 3 (CSCA): PHILIPPINES, Leyte Is(land), Mt. Balocaue, v.2007, local collector; 20 paratypes: 3 33, same data as holotype; 2 33, 1 Ƥ, 3 unsexed, same data except June–Aug., 2006, D. Mohagan leg.; 2 33, 1 Ƥ, Mt. Balocaue, Mahaplag, 5–10.iv.2009, local collector; 1 3, Mt. Balocaue, 15–19.vi.2009; 2 33, Mt. Balocaue, vi.2009; 4 33, Leyte Is., Mahaplag, Hilusig, Mt. Balocaue, August 2009. Paratypes are deposited in CLBC and COTJ.

Etymology. The name for this species is for the generally all green habitus.

Remarks. This is the second species of Coraebosoma that lacks any elytral vestiture in the form of pubescent spots and/or fasciae. As indicated in the key below, it comes nearest to C. violaceum Bellamy , which is blue-purple to violet in color, and from Mindanao.
