Kelly and Nel—Revision of some Mesozoic Odonata from England and Antarctica 92(6):1035–1048 1045


material held in Paris at the Muséum National d’Histoire Naturelle (examined by AN), the Late Triassic–Early Jurassic Russian and Central Asian material (checked at the Paleonto- logical Institute of the Russian Academy of Sciences in Moscow by RSK and Dmitry Vassilenko), and the Late Triassic–Early Jurassicmaterial fromChina held at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (examined by RSK). The specimen does not fitwith any family diagnosis already described and so we tentatively erect a new family for this species in the hope that further, better-preserved specimens will be found and described in the future.


Clade Isophlebioptera Bechly, 1996


Family Selenothemistidae Handlirsch, 1939 Genus Caraphlebia Carpenter, 1969


Type species.—Caraphlebia antarctica Carpenter, 1969.


Diagnosis.—A very well-defined CuA2 directed toward pos- terobasal side of hindwing. Caraphlebia antarctica Carpenter, 1969


1969 Caraphlebia antarctica Carpenter, p. 419, fig. 1. 1993 Caraphlebia antarctica; Nel et al., p. 259, fig. 221.


Holotype.—USNM 165874, part and counterpart (Fig. 8), Fer- rar Group, Mawson Formation; Early Jurassic, lower Lias (possibly Hettangian−Sinemurian); Carapace Nunatuk, South Victoria Land, Antarctica.


Diagnosis.—Hindwing CuA2 quite distinct, directed toward posterobasal margin of wing.


Description.—Primary antenodals present, Ax1 basal to arcu- lus, Ax2 distal to it, arculus closer to Ax1 than to Ax2. Cross- veins between RA and RP basal to expected position of subnodus; postnodal crossveins not visible. Pterostigma very long and narrow, but apparently distally incomplete. Post- discoidal area not distally narrowed. Area between RP3/4 and IR2 apparently distally broadened. Oblique veins not preserved. Nodal structures very poorly preserved. RP2 and IR1 not dis- cernible. Discoidal cell poorly preserved, but quite short and with distal side MA2 twice as long as basal side (without any trace of subdivision into hypertriangle and triangle, as figured by Carpenter, 1969). Subdiscoidal space broad, with posterior side (AA and CuA) convex. Basal part of CuA short, CuA2


Figure 8. Holotype of Caraphlebia antarctica Carpenter, 1969 (USNM 165874), Carapace Nunatak (Hettangian to Sinemurian), photograph and reconstruction. Ax0 = first branch of primary antenodal crossvein; Ax1 = second branch of primary antenodal crossvein; Ax2 = third branch of primary antenodal crossvein; Arc = arculus; CuA1 = distal branch of anterior cubitus; IR2 = intercalary radial vein 2; MA = anterior median; MP = posterior median; RA = anterior radius; RP1 = first branch of posterior radius; RP2 = second branch of posterior radius; RP3/4 = third/fourth branch of posterior radius.
