Forewing, RP+MA forking distal to MP forking.
Description
Holotype, CNU-MEC-NN2011076p/c (Figs 5A–D), a well preserved specimen in dorsal view, with outspread clear wings, but parts of body visible. Some segments of head, thorax, legs visible, but faint. Wings: Right forewing, length 8.4 mm, width 5.5 mm, broadly oval with clear venation, RP forking distal to MA forking; MP2+3 forking at about the same level of the forking of MA; the stem of MP3 about three times as long as the stem of MP2+3; with one crossvein between MA and MP1+2+3, and between MP2+3 and MP4. Left forewing is similar to right forewing, but the apex of the wing absent. Right hind wing, length at about 7.5 mm, width 4.6 mm, similar to forewing, but smaller, and overlapping with forewing partially. Left hind wing is similar to left hind wing, but partly folded as preserved. There are many spots on all four wings, symmetric between left and right wings. Paratypes: CNU-MEC-NN2009319 (Fig. 5E), a partially preserved specimen with forewings and one hind wing, but body absent; forewing, length 9.0 mm, width 5.4 mm, RP forking distal to MA forking; MP2+3 forking at about the same level of the forking of MA; the stem of MP3 about three times as long as the stem of MP2+3. CNU-MEC-NN2011074 (Fig. 5F), a specimen with one complete and clear forewing, length 7.4 mm, width 5.2 mm, RP forking distal to MA forking; MP2+3 forking at about the same level of the forking of MA; the stem of MP3 about three times as long as the stem of MP2+3. CNU-MEC-NN2011069 (Figs 6A, B), a partially preserved specimen, with complete left wings and most of body except for the terminalia, but incomplete right wings in dorsal view. Wings: right forewing, length 11.2 mm, width 7.5 mm, broadly oval, field between C and RA wide; RP forking distal to MA forking; MP2+3 forking distal to the forking of MA; the stem of MP3 about twice as long as the stem of MP2+3; CuP, 1A, 2A, single. Right hind wing is similar to forewing, but slightly smaller. Left wings partially preserved. CNU-MEC-NN2011078 (Figs 6C, D), an almost preserved specimen in dorsal view, with outspread clear wings, but parts of body absent. Wings: Left forewing, length 10.7 mm, width 6.4 mm, RP forking at the same level of the forking of MA; MP2+3 forking basal to the forking of MA; the stem of MP3 about four times as long as the stem of MP2+3; with one crossvein between MP3 and MP4, and between 1A and 2A; CuP, 1A, 2A single. Right forewing, similar to left forewing, but individual asymmetry is shown by right wing having MP3 with two branches, not the typical one branch in the left wing. Hind wings, length 8.2 mm, width 6.2 mm, similar to forewings but smaller, and partially preserved. CNU-MEC-NN2011077 (Fig. 6E), a partially preserved specimen with complete hind wings but parts of forewings and body; Forewing, length at about 10.3 mm, RP forking at the same level of the forking of MA; MP2+3 forking basal to the forking of MA; the stem of MP3 about three times as long as the stem of MP2+3; Hind wing, length at about 7.9 mm, width 5.0 mm.
Material
Holotype CNU-MEC-NN2011076p/c, Paratypes CNU-MEC-NN2011078, CNU-MEC-NN2011077, CNU-MEC-NN2011069, CNU-MEC-NN2009319, CNU-MEC-NN2011074, deposited in CNUB.
Type locality and horizon
Daohugou Village, Ningcheng County, Inner Mongolia, China, Jiulongshan Formation, Middle Jurassic (Bathonian-Callovian boundary interval, ca 164–165 Ma).
Etymology
The specific name is dedicated to Ms. Janet Angeline for her professionalism, dedication and accomplishments in her field and providing inspiration and support to CKS’s palaeontology studies.
Remarks
These six specimens exhibit differences in the characters of “RP forking vs. MA forking”, “MP2+3 forking vs. MA forking” and “Length ratio of the stem of MP3 and the stem of MP2+3”, which are considered as intraspecific variations.
