Taxonomy from Wang et al., 2016. Amended diagnosis from Wang et al., 2016, p. 73; "Head massive, circular or cube-like; mandibles curved, strong and sickle-like; pronotum short and wide; the first antennal flagellomere equal to head in length, but eight times as long as the second flagellomere; forewing pterostigma variable, completely sclerotized or partly sclerotized, or just membranous; M diverging from M+Cu at much larger angle than Cu; 1-RS proclival or somewhat vertical; angle between 1-M and RS+M almost 90°; 1cu-a distal to the middle of cell 1mcu or located at middle; 2r-rs almost in line with 2r-m; hind wing with 1r-m rather long, as long as or slightly shorter than 1-M."

From Peng et al. 2015, p. 2: "The systematics of Mesozoic psychopsoids is very complicated and confused. This group of Neuroptera includes taxa with broad and multi-veined wings that are currently classified in five families, i.e. Osmylopsychopidae, Brongniartiellidae, Psychopsidae, Kalligrammatidae and Aetheogrammatidae (Makarkin et al. 2013). Kalligrammatidae and Aetheogrammatidae are easily distinguished from other psychopsoids, whereas the Mesozoic members of the three other families (i.e. Osmylopsychopidae, Brongniartiellidae and Psychopsidae) hardly differ from each other.". Determined in Mai 2023 by Dr. Vladimir N. Makarkin, Institute of Biology and Soil Sciences, Far Eastern Branch of the Russian Academy of Sciences, Vladivostok, Russia: "This is a species of Osmylopsychopidae, possibly new."

Taxonomy from Fossilworks.com. Diagnosis for the genus from Yang et al. 2012, p. 4: 'Large neuropterans (forewing 50–75 mm long) with the following character states: labial palpi stout, relatively short; antennae stout, filiform, apparently much shorter than forewing length; two tibial spurs straight, shorter than basitarsus; claws big, strongly curved; in both wing, humeral veinlet well-developed, strongly recurrent, branched; presumed ScA short, fused with ScP within humeral area; membrane covered with dense, long hairs; RA (or ScP+RA) entering margin well before wing apex; subcostal crossveins numerous; radial crossveins irregularly spaced, not forming gradate series; in the forewing, MP, CuA, CuP dichotomously branched; presumed AA1+2 very short (found in Parakseneura gen. nov.); AA3+4, AP1+2, AP3+4 deeply forked; in hind wing, presumed AA1+2 very short (found in Pseudorapisma gen. nov.); proximal half of hind wings considerably wider than distal.' Determined by Dr. V. Makarkin, Academy of Sciences Vladivostok, Russia, as Paraksneura sp. It might be P. albadelta.

Thoughts on this? 3.26 cm, from Ningcheng, inner Mongolia. Jurassic. Ningcheng is the Daohugou beds of the Tiaojishan Formation. My first thought is it could be a mammal. But thats just a guess becausr of its strangeness.

Taxonomy from Wang et al. 2009. Daouhugounectes primitivus is a predaceous water beetle grub with raptorial forelegs and natatorial mid- and hindlegs. Diagnosis from Wang et al. 2009, p. 653." Head transverse, narrowing anterior of the base; nasale with rounded lateral lobes. Mandible with retinaculum near its middle. Prothoracic tergite somewhat longer than meso- and metathoracic tergites. Legs relatively short; mid- and hindleg distinctly longer than foreleg, their femora, tibiae and tarsi subequal in length, tibae slightly dilated at apex, tarsi roundly dilated anteriorly. Forelegs with sparse strong setae; meso- and metafemora with sparse thin hairs at posterior margin, tibiae and tarsi with short oblique setae and long think hairs along both sides. Abdomen with nine segments, seven of them transverse; sclerites in tergal position; sclerite VIII almost circular, curved ventromedially. Small subquadratic segment IX present between urogomphi. The closing apparatus of the spiracles on segment VIII weakly developed; trachea with helical thickening weak (compared to that of Coptoclava). Urogomphi approximately 2.5 times as long as tergite VIII." Line drawing from Wang et al, 2009 (scale bar 5 mm): Reference: B. Wang, A. G. Ponomarenko, and H.-Ch. Zhang (2009): A new coptoclavid larva (Coleoptera: Adephaga: Dytiscoidea) from the Middle Jurassic of China, and its phylogenetic implication. Paleontological Journal 43(6):652-659.

Taxonomy from Wang & Rose 2005. Revised diagnosis from Wang & Rose 2005, p. 524: "Mesozoic salamander showing combination of larval and adult features indicating neoteny or incomplete metamorphosis. Larval features include: external gills; toothbearing coronoid; larval-shaped pterygoid; short maxillary arcade with underdeveloped maxilla. Adult features include: extensive medial contact of nasals; posteriorly directed, dentigerous vomerine bar in the palate. Differing from other Mesozoic salamanders in the following combination of character states: 15–16 presacrals; vertebrae with short transverse processes; ribs unicapitate and proximally expanded; anterior process of pterygoid directed anteromedially towards vomer, rather than anterolaterally towards posterior end of maxilla; vomer with large tooth patch anteriorly and longitudinal dentigerous bar posteriorly; nasals large with no anterior notch; frontal with no anterolateral extension; alary process of premaxilla about two-fifths width of premaxilla; phalangeal formulae of 2-2-3-2 and 2-2-3-3-2 for manus and pes, respectively."
