It refers to the conspicuous color markings on the species’ head and pronotum.</p><p>Locality and horizon.</p><p>The specimen was included in amber found in Hkamti, Sagaing Division, Myanmar or Tanai, Kachin State Burma, Myanmar, two nearby amber mining locations. The amber from Hkamti is ca. 110 My and the amber from Tanai ca. 99 My old.</p><p>Holotype.</p><p>Male. Specimen part of the LIB-Hamburg collection; collection number GPIH 07231 (ex coll. Martin Husemann, coll. no. MH 0086).</p><p>Diagnosis of species.</p><p>As for genus (monotypic).</p><p>Description.</p><p>A fully preserved specimen, except for left metathoracic leg.</p><p>Measurements: Values given with a “ ca. ” indicate measurements based partly on estimation. Body-length ca. 1.83 mm. Head height 0.68 mm. Compound eye height 0.31 mm, width 0.21 mm. Antenna length 0.85 mm. Pronotum length 0.54 mm, height 0.4 mm. Forewing length 0.55 mm, hindwing length 1.64 mm. Prothoracic leg: femur 0.38 mm long. Tibia 0.36 mm long. Mesothoracic leg: tibia 0.5 mm long. Femur / Tibia width = 1.07 (at mid of both). Metathoracic leg: femur ca. 0.86 mm long, 0.51 mm wide. Tibia ca. 0.79 mm long, ca. 0.09 mm wide (around mid-length). Tarsus&gt; 0.31 mm long. Cercus 0.15 mm long. Paraproctal lobe ca. 0.05 mm long. Subgenital plate 0.18 mm long.</p><p>Head: Antennae 10 - segmented, moniliform. Pedicel and scape wider than antennomeres. Head with two small bumps on the vertex in front of the compound eyes. Compound eyes placed laterally on the head. Head with distinct coloration; a lighter area crosses the eye dividing it into two equal parts and continuing on the dorso-lateral portion of the head. Ocelli not seen.</p><p>Thorax: Pronotum with similar light / dark contrasting colors as head, but here the base color is light and several dark spots are scattered across the surface. Pronotum without elevation. Both fore- and hindwings present. Forewings with same color pattern as pronotum, hindwings uniformly dark. Hindwing slightly longer than abdomen.</p><p>Legs: Prothoracic leg: femur bearing some long hairs. Tibia slightly inflated, completely covered with shorter to longer hairs. Apically with three dactyls, the longest of which is 0.05 mm long. Tarsus slender, only distal segment can be seen, bearing two curved claws.</p><p>Mesothoracic leg: femur with some short hairs on both margins. Femur rather slender towards coxa, becoming wider towards tibia. Tibia slightly inflated, but not as wide as distal part of femur. Tibia apically with dense long hair. Tarsus slender with two claws.</p><p>Metathoracic leg: femur inflated along its entire length. Tiger stripe coloration, which can be seen on the metafemur of the specimen is probably due to fissures in the amber and not actual coloration. Connection to tibia damaged. Tibia with lateral carina that runs until apex. Fin with distinct serration. Subapical and apical spurs present, approximately the same length. Tarsus proportionally long and rather thin. Ventrally with eight to nine hairs. Apex of tarsus hidden behind mesotibia.</p><p>Abdomen: Epiproct short, not covering cercus. Cercus one-segmented, cylindrical in shape and with many long hairs. Paraproct distinct with paraproctal lobe in ventral position. Paraproctal lobe significantly smaller than cercus (both length and width), cylindrical without hairs. Subgenital plate elongated, approximately the length of the cercus and with long hairs; one especially long hair on the apex. Subgenital plate mostly dark in coloration becoming slightly lighter towards apex. Cercus completely of lighter color.</p><p>Remarks.</p><p>The new genus is assigned to Ripipterygidae based on the following characters: 1) cercus one-segmented. 2) Mesotibia not inflated. It is most similar to Burmaripipteryx Zhao, Xu, Jarzembowski, Fang &amp; Xiao, 2023 but differs from the latter by the two bumps on its forehead and the coloration pattern of the head, pronotum as well as external genitalia ( B. oblongus Zhao, Xu, Jarzembowski, Fang &amp; Xiao, 2023, only species of the genus, has cerci with the basal half light in color and the distal half dark, while the subgenital plate is completely light. Head and pronotum show no noteworthy color pattern). These characters also differentiate Abaddonella from any other ripipterygid-genus. The underdeveloped paraproctal lobes of this genus and also Burmaripipteryx (much smaller than cerci, of no distinct shape and without apical setae) are rather unusual for Ripipterygidae . According to Song et al. (2015), the estimated split between the lineages of Ripipterygidae and Tridactylidae occurred 153.45 Mya, ca. 50 My prior to the formation of the Kachin amber from Tanai. Maybe, at this point in time the separation of the two families had not yet been fully completed and a third lineage, ancestral to both, still existed. This is a question that will be answered with more findings of Tridactyloidea from Kachin amber in the future. For now, we follow Zhao et al. (2023) and place Abaddonella in Ripipterygidae .</p></div>	https://treatment.plazi.org/id/4048BB840C9151E0AD10CF28F9F6B0C4	Public Domain	No known copyright restrictions apply.

Pronotum length 0.62 mm, height 0.38 mm. Prothoracic leg: femur ca. 0.35 mm long. Tibia ca. 0.27 mm long. Tarsus ca. 0.25 mm long (including claws). Forewing ca. 0.79 mm long. Hindwing ca. 1.53 mm long. Mesothoracic leg: tibia 0.39 mm long, 0.25 mm wide (max width). Tarsus 0.35 mm long. Metathoracic leg: femur 1.36 mm long. Tibia 1.41 mm long, 0.09 mm wide. Tarsus 0.32 mm long. Subapical spurs ca. 0.05 mm long. Apical spurs 0.08 mm long. Cercus 0.19 mm long. Paraproctal lobes 0.3 mm long (not including hairs). Ovipositor (longest valve) 0.17 mm long.</p><p>Head: Morphology uncertain due to internal damage in the amber.</p><p>Thorax: Pronotum without elevation. Very deep laterally, covering the entire height of the thorax. Fore- and hindwings present. Venation undiscernible (lines seen on the wings are fissures in the amber, not actual veins). Hindwings just as long as abdomen.</p><p>Legs: Prothoracic leg: Coxa big, about 2.5 × the width of femur with sparse hair. Trochanter halfway in width between coxa and femur. Femur with numerous hairs. Tibia with numerous hairs, too. Apically with four dactyls, the longest of which is 0.05 mm long. Tarsus damaged. Slender without hair and ending in two claws.</p><p>Mesothoracic leg: only tibia and tarsus can be seen. Tibia with very distinct shape, looking like it is made up of two triangles, where the distal half is inserted into the bigger (both wider and thicker) proximal half. Greatly inflated. Apically with some hairs. Tarsus two-segmented, slender, no hair and with two claws.</p><p>Metathoracic leg: femur apically with sparse hair. Tapering toward apex, only somewhat inflated. Tibial fin with serration. A pair of subapical and apical spurs. Apical spurs with four conspicuous hairs on ventral margin. Tarsus blunt with two rows ventrally, one metatibial fin serrated, the other with hair.</p><p>Abdomen: Proximal to abdominal apex are three fin-like appendages of which the anterior two have singe hair inserted. Posterior fin probably lost the hair during preservation. More fins may be present but are covered by the metafemur. Cercus one-segmented, cylindrical in shape and setulose. Paraproctal lobes two-segmented, longer than cercus. Distal segment swollen, clavate in shape with distinct long hairs, especially on the apex of distal segment. Ovipositor visible, with narrower pointed end.</p><p>Remarks.</p><p>Based on the structure of the external genitalia (cercus one-segmented; paraproctal lobes longer than cercus, modified in shape and with distinct apical hair; ovipositor visible), the new species should be assigned to Ripipterygidae . However, this family is usually recognized by an uninflated mesotibia, too (Heads 2010). Some species from Burmese amber that were previously assigned to Ripipterygidae were noted to have an untypical mesotibia, for example Zhao, Xu, Cao, Jarzembowski, Fang and Xiao (2024) remarked in their description of Kallosripipteryx zhangi “ mesotibia slightly fusiform, not slender as typical of ripipterygids ”. In Naginipteryx pinna, this character is extremely pronounced, with an inflation of the mesotibia surpassing what is common for Tridactylidae (who are characterized by an inflation of the mesotibia) (compare for example Latedactylus longapedi Zheng, Cao &amp; Gu, 2023 or Burmadactylus tenuicerci Fan, Gu &amp; Cao, 2023). As suggested for Abaddonella nwarrngaal gen. et sp. nov. (see above), this strange combination of characters may indicate the presence of an ancestral lineage (or perhaps several ancestral lineages?) of Tridactyloidea in the Burmese amber forest that had not yet completed the evolutionary separation between Tridactylidae and Ripipterygidae .</p></div>	https://treatment.plazi.org/id/D0B2BC8FC1625FD196CAFAD5AD40AD80	Public Domain	No known copyright restrictions apply.

It is also found in the mythology of Myanmar. Nagas are usually portrayed as half-human, half serpent beings, but can also be found as dragons.

External genitalia very similar to Yakkhapipteryx Schall, Cao &amp; Husemann, 2025 more specifically Y. gracilis (Gu, Zheng, Cao &amp; Yue, 2022) (this includes morphology of the cerci, paraproctal lobes and ovipositor valves): cercus one-segmented, cylindrical and setulose with long hairs. Paraproctal lobes two-segmented and longer than cerci, apically swollen and clavate with distinct long hair. Ovipositor visible, approximately as long as cerci, valve rather thick (more similar to Y. gracilis than Y. mira (Gu, Zheng, Cao &amp; Yue, 2022)) . Differs from Yakkhapipteryx by 1) the mesotibia being distinctly inflated and triangular in shape. 2) Ventral appendages with an inserted hair on the abdomen. 3) A blunt (rather than pointed) metatarsus with one row of serration and one row with hairs (rather than no row).</p></div>	https://treatment.plazi.org/id/F6875E61AC1D578D9E1A3AD734FB1A0D	Public Domain	No known copyright restrictions apply.
