Taxonomy from Fossilworks.org Species diagnosis from Nakamine et al. 2020, p. 20: "Protibia five slight protrusions on the proximal area of ventral ridge, bearing two spines on the distal area of ventral ridge (three in M. cristata). Hindwing RP divided into five branches; one intra-RP crossvein (4rp4-rp5) present." Line drawing of (d) left forewing; (e) right forewing; and (f) left hindwing from Nakamine et al. 2020, p. 21; Scale bar 1 mm. References: Nakamine, H., Yamamoto, S., & Takahashi, Y. (2020).

Taxonomy from Makarkin 2016. From Makarkin 2016, p, 127: "Derivation of name. From the Greek paradoxos [παράδοξος], paradoxical, strange, and Sisyra, a genus-group name of the family, referring to its mouthparts, which are unlike those of other sisyrids. Gender feminine. Diagnosis. May be easily distinguished from all other known genera of Sisyridae by a combination of the following character states: enormously long siphonate mouthparts likely lacking mandibles [mandibulate mouthparts in other sisyrids]; several setiferous calluses on head, pronotum present [absent in other sisyrids]; very long, slender hind legs (hind tibia and tarsus together more than 2/ 3 of forewing length) [hind tibia and tarsus together ca. 1/2 of forewing length or shorter in other sisyrids]; deeply forked CuP, AA1 in forewing [these shallowly forked or simple in other sisyrids]; complete inner gradate series of crossveins in hind wing [incomplete in other sisyrids]; RP with five branches in hind wing [two-three branches in other sisyrids]." Quote from a private message from Dr. V. Makarkin (October 2022): 'Dear Thomas, This specimen belongs certainly to Paradoxosisyrinae and is very similar to Paradoxosisyra groehni. But in Burmese amber, there are rather numerous other species of this subfamily, partly described in the attached paper. So, it may be identified today as 'Paradoxosisyrinae similar to Paradoxosisyra groehni' Identified by Dr. V. Makarkin, Paleontological Institute of Russian Academy of Sciences, Moscow.

Taxonomy according to GBIF: Smarididae are large predatory mites with long oval bodies that are clearly pointed at the front. The (recent) predatory mites are usually red in color and densely hairy with slender, sometimes very long legs. They have either one or two pairs of eyes. Identified by Dr. J. Dunlop (Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science in Berlin, Germany) and Dr. J. Makol (Department of Invertebrate Systematics and Ecology, Wrocław University of Environmental and Life Sciences, Poland) as Smarididae indet. References: Dunlop, Jason A., Frahnert, Konrad, and Makol, Joanna (2018). A giant mite in Cretaceous Burmese amber. Foss. Rec., 21, 285–290. Wohltmann, Andreas (2010).

Proterosceliopsidae are parasitoid wasps that lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these. This is a female. Taxonomy according to Fossilworks.org. Diagnosis for the family Proterosceliopsidae according to Talamas et al. 2019, p. 20: “Antenna with 14 or 15 antennomeres; malar sulcus present (Fig. 7); facial striae absent (Fig. 7); malar striae absent (Fig. 7); pronotal cervical sulcus present as a furrow of fine setation associated with glandular excretion (Figs 16, 48–49, 51–53, 59); mesopleuron with transepisternal line and mesepimeral sulcus (Figs 16, 51–53, 59, 63); T3–T5 and S3–S5 anteriorly with depressions associated with glandular excretion (Figs 29, 34, 56, 58, 62).” Several very similar looking species have been described from amber deposits in Myanmar: P. ambulata, P. plurima, P. torquata, P. masneri, P. nigon and P. wingerathi. A more exact assignment is not possible for me. Identified by oilshale as Proterosceliopsis sp. using Talamas et al. 2019. References: Ortega-Blanco J., McKellar R. C,, Engel M. S.

Taxonomy from Ribero 2003. Between thorax and abdomen sits an undefined ectoparasite, an Acari (mite, belonging to the arachnids), and sucks the body fluid of the crane fly. Diagnosis from Ribeiro 2003, p. 404: "Rostrum ca. 0.5 x the length of head; head ca. 0.81 X the length of palpi; stigma lacking; outer gonostylus almost straight, curved abruptly at tip, not bifid; interbases absent. Wing and head line drawing from Ribeiro 2003, p. 406: Identified by oilshale. Reference: Ribeiro, G.C. 2003. A new fossil Helius (Diptera: Limoniidae) from Burmese amber. Studia Dipterologica, 9: 403–408.

Characteristics of the family Pachytroctidae Head: Antennae usually have 15 segments. The first 4-5 segments of the antennae do not have sculpturing; other segments have ringed sculpturing (annulations). Eyes are relatively large, compared to related families. Legs: Tarsi have 3 segments. Hind legs are long and the femur is not flattened (as in Liposcelidae). Wings: Adults can be have full-length wings or short wings, or can be wingless. Full-length wings are held flat over back when at rest. Forewings are rounded. Forewing veins are distinct: Areola postica is narrow, long and flat. Pterostigma is not thickened (as in Psocomorpha). Vein M has 2 branches. Veins Cu2 and Cu1A reach the wing margin separately. Abdomen: Abdominal segments often partially membranous on back surface. Male: Clunium is absent. Phallosome is closed at the base with complex structures on the posterior end. Female: Subgenital plate sometimes has T-shaped sclerite, as in related families. Gonapophyses are complete and hairless: External valve is large without lobes. References: Dany Azar, Diying Huang, Chenyang Cai, André Nel. 2015.
