Graphorn gen. nov. ( Figs. 1-5 )

Type species: Graphorn bicornutus sp. nov., by present designation.

Description. General body features: compact body ( Fig. 1 ), dorsal coloration yellowish-cream to ochreaceus. Dorsal surface finely and densely punctate, with concolorous or dark brown punctures. Ventral surface yellowish, with punctures fine, dense, nearly concolorous with body surface.

Head: Elongate apically ( Fig. 4 ), slightly longer than wide, paraclypei slightly longer than clypeus, but not contiguous anteriorly; eyes prominent; antenniferal tubercles elongate, each with a large, acute tooth; antennae 5-segmented; bucculae concave ventrally, nearly truncate posteriorly, each with a triangular tooth near anterior apex; rostrum 4-segmented, apex reaching metacoxae.

Thorax: Pronotum hexagonal ( Fig. 4 ) with humeral angles prominently spinose, anterolateral margins strongly crenulate. Scutellum subtriangular, relatively large, without basal foveae, submarginal ivory callus in each basal angle, scutellar apex broadly rounded. Thoracic sterna carinate medially. Ostiolar peritreme short ( Fig. 2 ), auriculate, evaporatoria small, not reaching half way to lateral margin of metapleuron or posterior margin of mesopleuron; ostiolar plates narrow, convex, slightly darker than evaporatoria. Legs with strong spine-like setae; superior surface of each tibia sulcate; tarsi 3- segmented.

Abdomen: Connexiva with posterolateral angles prominent, acute; base of abdomen lacking tubercle or spine. Genitalia: Female paratergites apically acute, 1 st and 2 nd gonocoxae acute, convex posteriorly, mesial margins convex.

Male unknown.

Etymology: Graphorn (Gender masculine), from the fictional creature created by J.K. Rowling in the book ‘ Fantastic Beasts and Where to Find Them’. Graphorns are a breed of large hump-backed horned creatures. These are known to have two large golden horns, similar to the humeral spines of this new genus. In addition, the crenulate pronotal margins and elevated pronotal disk resembles the large dorsal hump of the graphorns.
