155F95C10BDA5C7D9858EED28EAF6E10.taxon	diagnosis	Diagnosis. Antennae four segmented, long, but not longer than the body (head, thorax, and abdomen). First antennal segment short and robust (slightly longer than wide or about equal in length and width; always shorter than head length); second and third segments ornamented and quite variable in form interspecifically (can be marked throughout with granulation, setation, or prominent tubercles with margins straight or with spination), each at least three times longer than wide, with the third segment slightly wider and longer than the second segment; and the fourth segment is only slightly longer than head length, flat, and paddle-like, lacking intricate features / expansions as present on the second and third segments. Head approximately as long as wide, compound eyes spherical and variable in their size (can be large, occupying most of the lateral margins, or narrower, restricted to the center third and strongly protruding), located on the center of each side of the head. Pronotum with a margin that expands to the posterior third then contracts slightly. Mesonotum gently expands to the midline and then gently contracts to the posterior. Metanotum with margins that can be parallel or slightly rounded. Abdomen slender, notably longer than wide, with parallel margins. Legs stout, not particularly long. Femora approximately two times as wide as the tibiae, but of similar lengths. Tarsi with two segments, bearing two claws.	en	Cumming, Royce T., Tirant, Ste ́ phane Le (2021): Drawing the Excalibur bug from the stone: adding credibility to the double-edged sword hypothesis of coreid evolution (Hemiptera, Coreidae).

155F95C10BDA5C7D9858EED28EAF6E10.taxon	etymology	Etymology. The generic name is derived from Latin prefix ferri (meaning weapon) and Latin antenna (meaning yardarm of a ship / sail yard which was the origin of the " feeler or horn " of an insect; https: // www. etymonline. com / search? q = antenna). This genus epithet is referring to the weapon-like appearance of the antennae of these insects (Fig. 2 A, B). Gender is neuter.	en	Cumming, Royce T., Tirant, Ste ́ phane Le (2021): Drawing the Excalibur bug from the stone: adding credibility to the double-edged sword hypothesis of coreid evolution (Hemiptera, Coreidae).

Flat and round rectangular piece of amber, approximately 1.0 cm by 1.1 cm with high clarity and small debris throughout that does not black visibility of the specimen (Fig. 3 C). Specimen partially complete yet well-preserved, likely fourth instar. Missing the terminal two or three segments of the abdomen. Deposited in the Montreal Insectarium (IMQC). Unknown sex. Figure 3.

A3294CD0433750469CC6345C9A4BE180.taxon	etymology	Etymology. Noun in apposition, given for Excalibur, the mythical " sword in the stone " which was first described in the epic poem Merlin (about the mythical advisor to King Arthur), written by the French poet Robert de Boron sometime between 1195 - 1210 (Reeve and Wright 2007) which was a reworking of Geoffrey of Monmouth's " Historia Regum Britanniae ", completed c. 1138 (Wright 1985). Within this poem is the first mention of Excalibur being the sword in the stone, which could only be removed by the true king of England. We felt that this specific epithet was fitting as this group of insects with exaggerated antennae were first described as a possible " double edged sword in evolution " as these elaborate antennae went extinct (Du et al. 2021). We felt this witty description, coupled with the insect being trapped in stone (amber) was fitting for such a long lost, and therefore mythical species.	en	Cumming, Royce T., Tirant, Ste ́ phane Le (2021): Drawing the Excalibur bug from the stone: adding credibility to the double-edged sword hypothesis of coreid evolution (Hemiptera, Coreidae).
