Head with epistoma feebly convex on disc, finely microreticulate, distally confusedly rugose, on disc finely, sparsely and regularly punctured; clypeus subtruncate anteriorly, widely rounded laterally, thickly bordered, the edge feebly upturned and sparsely, rather shortely ciliate laterally; genae subauriculate, obtusely
rounded, sparsely elongately ciliate, distinctly protruding more than eyes; frontal suture distinctly impressed; front distinctly regularly punctured.
STRUCTURE: Head: Clypeus elliptoid, extending below bucculae (Figs 2b, 4c, d); frontal plate evenly arcuate, obtusely
tapered posteriorly (Figs 2b, 4c, d), extending anteriorly beyond fronto-clypeal suture, sometimes with a toothlike appearance (Figs 2b, 4c, d).
Aedeagus curved ventrad, bent in "C" shape, shaft slightly compressed, with small retrorse spines, abruptly narrowing at distal fourth; phallotrema subapical on dorsolateral surface; periandrum as a transverse strut obtusely
bent caudally against the phallotheca, periandrum and anal segment in close contact; connective long, stout, shortly braced to the periandrum above tectiform structure.
4 cm, green, glabrous, obtusely
angulose, partially covered by the bracts mainly before anthesis, stipes 1-2 x 0.
Posterior margin convex, rounded or obtusely
Pronotum short, constricted in the middle, brown, with the deflexed lobes more yellowish, impress-punctate, rugose behind and with a very slight median carina, hind border obtusely
rounded; deflexed lobes with the lower margin nearly straight and strongly rounded at the hinder angle; the transverse sulci dark, well-marked, the hind slucus placed beyond the middle.
4 mm, lobes narrowly elliptic to obovate- lanceolate, obtusely
carinate, apex acute and apiculate, glabrous, whitish-green; petals 36- 38 mm long, connate at the base for 7-10 mm, lobes sublinear, erect, 29-39 x 6 mm, green toward the apex except for the white apical margins, bearing 2 long fimbriate appendages at the tube apex, as well as 2 conspicuous longitudinal callosities slightly shorter than the filaments, apex obtuse-cucculate, corolla tubular; filaments the antepetalous ones adnate to the petals for 20-27 mm, the antesepalous ones adnate to the petals tube and free above it; anthers ca.
0, anterior margin straight, posterior margin obtusely
excavated, dorsal disc almost parallel to vertex at base, median carina distinctly ridged and percurrent, with one lateral carina on each side between eye and tegula (Figs.
5 mm, connate at base for 2-3 mm, entire, greenish, subdensely and coarsely white-lepidote, the posterior ones carinate with keel slightly decurrent on the ovary, the anterior one obtusely
if at all carinate; petals broadly spatulate, 31-33 x 9 mm, connate at base for 2-4 mm in a common tube with the filaments and style, white, the free lobes broadly obovate, obtuse to slightly emarginate, suberect at anthesis, distinctly exceeding the stamens, bearing 2 longitudinal callosities ca.
Pygofer in profile much shorter dorsally than ventrally, laterodorsal angles obtusely
rounded, not produced caudad, lateral margins excavate at middle, each very strongly produced dorsad with medial pillar-like projection (Fig.
5 x 4-5 cm; blades sublinear, nearly flat near the base, canaliculate and obtusely
carinate abaxially at middle, and subulate toward the apex, suberect to nearly erect, 10-12 cm long, ca.
9-1 cm, terete, greenish to winish, glabrous, bearing 2 (upper ones) to 3 (basal ones) sterile bracts exceeding the internodes and arranged at the apex of the stipes, obtusely
if at all carinate, the terminal branch erect at base and turning suberect-recurved toward the apex, ca.
