9 cm wide, ovate, apiculate, with an incurved apex, cucullate, in the upper part hyaline and with slightly undulate margins, slightly lepidote, green with irregular red spots, imbricate during anthesis, carinate, nerved in the lower part, erect, covering the sepals.
73:1), with many setae at apical margin; anterior margin of the clypeus rounded and partially rugose, basal third of the elytral intervals convex, ventral posterior marginal line face of the mesofemur and metafemur incomplete, base of all abdominal sternites visibly fluted, mesosternum carinate between the mesocoxae, mesotibia- and metatibia with accessory spine and one seta between it and the inferior spur, abdominal sternites with homogeneous punctation, anterior edge of pygidium punctate, front and disc of pronotum with heterogeneous punctation, scutellum longer than wide.
Pronotum: unicarinate, with a single median longitudinal carina; anteriorly without a small hood, but with a narrow collar terminating before lateral areolate margin; laterally pronotum without extensive areolate paranota, but carinate, and with anterior third enlarged, reflexed into notum and with 2-3 areoles; calli dark brown to black; pronotal width [male] 0.
The specific epithet is derived from the Latin multi meaning many, and carinata meaning carinate, in relation to the several carinae or ridges present on the pronotal surface.
Inflorescence pendulous, 40-70 x 10-15 cm with 12 to 30 branches; primary bracts like the upper scape bracts but without the long blade, mostly apiculate, mostly shorter than the peduncles, grey-green to pink; branches spreading at ca 30[degrees] from the axis with an ebracteate 3-7 cm x 2-4 mm flattened peduncle that exceeds nearly all of the primary bracts; the fertile portion 4-8 x 1-2 cm, 4 to 10 flowered; floral bracts elliptic, acute, 20-26 x 8-10 mm nerved, variably carinate, tightly imbricate in life, spreading when dried, glabrous except for a few pale fimbriate trichomes at the very apex, bright magenta pink, somewhat glaucose.
Vertex slightly depressed, without any anterior transverse black spot, and deeply transversely carinate (Fig.
3: 1), widest at apical fourth, median carina broad, lateral margins carinate, area between median carina and lateral margins shallowly depressed.
5-3 cm in diameter (including the floral bracts), 10 to 30-flowered; floral bracts ovate, acuminate and apiculate, pungent, coriaceous, the basal ones carinate the upper ones slightly if at all carinate toward the apex, v-shaped, slightly exceeding the sepals but strongly recurved toward the apex and exposing them, green, finely nerved, coarsely and densely cinereous-white-lepidote on both sides, 19-20 x 11-14 mm, margins densely spinulose, spines 0.
Male pygofer with ventral angles distinct, diaphragm well-developed, armature thickened, carinate along midline, caudally expanded.
5 mm, free, entire, pale green, finely nerved, thin in texture, inconspicuously white-lepidote along the central-distal portion to glabrous, the adaxial ones carinate with keels decurrent on the ovary, the abaxial one obtusely if at all carinate; petals spathulate, apex rounded and remotely apiculate, ca.
The elytra have dotted longitudinal lines (= striae) along their entire length; the interstriae are weakly carinate.
