Description. Holotype Male.

Head. Head laterally wide, with frons and gena smooth, in frontal view ( Fig. 2B View FIGURE 2 ); fastigium-vertex small and bilobated, in frontal view ( Fig. 2B View FIGURE 2 ); Globular eyes ( Figs. 2B–D View FIGURE 2 ). Mandibles symmetric ( Fig. 2B View FIGURE 2 ).

Thorax. Pronotal disc subrectangular, anteriorly convex, laterally round and posteriorly straight, in dorsal view ( Fig. 2C View FIGURE 2 ); lateral region with rows of thin and big spines, bigger spines at medial region of pronotum; apical half spines directed frontwards and basal half spines directed backwards. Dorsolateral suture curved and concolorous with pronotal disc ( Figs. 2C–D View FIGURE 2 ). Mesobasisternum triangular-shaped, anteriorly concave and posteriorly narrow ( Fig. 2G View FIGURE 2 ). Lateral lobes of mesobasisternum anterolaterally and laterally concave, posterolaterally forming a round tip, posteriorly concave ( Fig. 2G View FIGURE 2 ). Metabasisternum triangular-shaped, anteriorly concave and posteriorly narrow ( Fig. 2G View FIGURE 2 ). Lateral lobes of metabasisternum anterolaterally and laterally concave, posterolaterally forming a round tip, posteriorly slightly convex ( Fig. 2G View FIGURE 2 ).

Wings. Tegmina almost elliptical with round apex, presence of several asymmetrical black spots in rows on anterior and posterior margins, spots parallel to main branches of veins R, M and Cu ( Fig. 3 View FIGURE 3 ). Vein R slightly sinuous with several branches, branches almost straight reaching anterior margin of tegmina. Vein MA bifurcated near apex. Vein MP medially connected to vein CuA by two transversal veins, forming a lozenge-shaped cell. Vein CuA almost straight, parallel to posterior margin of tegmina, posteriorly with a transversal connection to vein CuP, forming an elongated triangular cell; medially with a short branch touching posterior margin of tegmina ( Fig. 3 View FIGURE 3 ). Left stridulatory file curved with rectangular large teeth; basal half teeth wider and farther apart; apical and basal teeth shorter than medial teeth ( Fig. 4A View FIGURE 4 ). Total length of left stridulatory file 2.8 mm, greater vein width of 0.5 mm and a total of 105 teeth ( Fig. 4A View FIGURE 4 ). Right stridulatory file slightly sinuous, with medial region almost straight ( Fig. 4B View FIGURE 4 ). Total length file of 2.5 mm, widest vein of 0.2 mm and total of 98 teeth ( Fig. 4B View FIGURE 4 ).

Legs. Fore femur straight; ventral inner side with three black spines triangular and thick; apical region with two small spines, in lateral view ( Fig. 2E View FIGURE 2 ). Fore tibia with tympanic region strongly enlarged and with tympanic cavity almost completely closed, forming a short crevice; tympanic region with a pair of dorsal spines; ventral side of tibia with six short spines ( Fig. 2E View FIGURE 2 ). Mid femur straight; ventral side with three black spines triangular and thick, apex with two spines, in lateral view ( Fig. 2F View FIGURE 2 ). Mid tibia with basal region wide and with shape elliptical, dorsal region with two short spines curved; ventral side of tibia with six straight short spines, in lateral view ( Fig. 2F View FIGURE 2 ). Hind femur elongated, with basal and apical region with similar width; ventral region with four pairs of black spines curved and thick, in lateral view ( Fig. 2A View FIGURE 2 ). Hind tibia slightly curved, with basal region wide progressively narrowing towards apex; dorsal and ventral region with two rows of several short and curved spines, in lateral view ( Fig. 2A View FIGURE 2 ). All legs with short bristles ( Figs. 2A, E–F View FIGURE 2 ).

Abdomen. Tergite X posteriorly straight ( Fig. 2I View FIGURE 2 ). Cerci hook-shaped in dorsal view; with apical half curved upwards, in lateral view ( Fig. 2J View FIGURE 2 ); cerci acuminated and curved inward, in dorsal view ( Fig. 2H–I View FIGURE 2 ); apex of cerci exceeding base of styli; cerci with several large bristles ( Figs. 2H–J View FIGURE 2 ). Subgenital plate subretangular, laterally straight and posteriorly bilobated, zone between base of styli straight ( Figs. 2H–J View FIGURE 2 ). Styli small and elliptical ( Figs. 2H–J View FIGURE 2 ).

Internal male genitalia. Not examined.

Coloration. Based on photos of preserved specimen ( Fig. 2 View FIGURE 2 ). General color yellowish-brown. Scape lightish yellow, pedicel black and other antenomeres dark yellow with black spots. Head with black stripe transversal and narrow posteriorly to eyes. Pronotal dorsal spines with outer side black and inner side yellow; bigger spines with tip black. Mesonotum and metanotum laterally with big black spot laterally. Tegmina with main branch of vein R black; veins M and Cu dark brown; marginal region of main veins and margins of tegmina with rows of asymmetrical black spots, forming simple dotted stripes on margins of tegmina and doubled dotted stripes on veins CuA and M. Femora with apex dark brown with black spots; mid and posterior femora with big black spines ventrally. Anterior and mid tibia with base and apex dark brown with black spots; mid region yellow. Posterior tibia yellow with basal and apical region with black spots; postero-ventral region with black spot on base, near spine. Cerci yellow with distal region black and tip yellow.

Female: Unknown.

Etymology. The epithet is a homage in memoriam to Catarina da Silva Motta, the first academic advisor of DMMM. Catarina was a notable lepidopterist who worked in the Brazilian Amazon as a researcher at the Instituto Nacional de Pesquisas da Amazônia. She was among the most generous and kindest person that DMMM has had the pleasure of meeting. Furthermore, she greatly contributed to collecting several groups of insects besides Lepidoptera , including this new katydid described in the present work.

Comments. Coronophyllum gen. nov. is an enigmatic katydid. The only known specimen was collected in the municipality of São Gabriel da Cachoeira, on the border with Colombia. This region is part of the Imeri Amazonian endemism area proposed by Da Silva et al. (2005), which is one of the least known and currently sampled regions in the Amazon, which corroborates the rarity of this new genus. It is very likely that Coronophyllum gen. nov. also occurs in Colombia, therefore, additional collecting expeditions in that region are essential for expanding knowledge of the distribution of this magnificent species.
