Body dark auburn (Fig. 3A–C), prothorax and elytra with both, scarce standing bowed, light brown, pointed and more regular standing raised, clubbed, elongate scales, more than five times longer than wide, rounded apicad. Rostrum shorter than pronotum (Figs 3C, E); in dorsal view weakly narrowed just behind antennal insertion, widening anteriad, and towards frons. Antennomeres subequal. Club of antennae oval (Fig. 3F). Prothorax as long as wide (L/B: 1.0) (Fig. 3A), weakly constricted before anterior margin; dorsal surface with coarse, polyhedric punctures separated by thinner ridges (Figs 3A, D). Basisternum flat and coarsely punctate (Fig. 3B). Procoxae separated by half of coxal diameter; mesocoxae separated by their diameter; metacoxae separated by less than twice their diameter (Fig. 3B). Externally visible part of scutellum small and pentagonal (Fig. 3I). Elytra elongate (L/B: 1.6–1.7), dorsally widest at shoulders, parallel along first third, attenuate from there to apex, hind wings present. Intervals as wide as striae, with sharp, dark and shiny tubercles, uneven elytral intervals weakly raised; raised (uneven) intervals on elytra with regularly arranged clubbed-elongate raised scales and scarce shorter, pointed recumbent scales; even intervals with irregularly arranged clubbed-elongate scales. Each puncture of striae laterally with a small granule and often with a tiny recumbent bristle at anterior margin. Meso-, metaventrites and abdominal ventrites coarsely punctate; each puncture with a thin clubbed and bowed, yellowish scale (Fig. 3B). Legs slender, femora clubbed, without teeth (Figs 3A–D). Tarsi with bilobed third tarsomere; claws free. Penis broad shovel-shaped, broadening apicad, tip rounded, dorso-ventrally flattened, with one v-shaped tube-alike internal sclerite (Fig. 6G–I). Female genitalia with c-shaped spermatheca (Fig. 6M), weakly sclerotized gonocoxites with elongate cylindrical styli (Fig. 6N). Ventrite 7 (Fig. 6O). Slight sexual dimorphism: males are a little smaller than females (Figs 3A, D, G–H).</p><p>Derivation of name: This species is dedicated to Dr. Michael Geiser (BMNH, London), an enthusiastic and gifted entomologist since his childhood.</p> |
