Uroleucon (Uromelan) lehri Zaitzev, Lelej, Storozhenko & Kurzenko, 2006


Uroleucon (Uromelan) lehri Zaitzev, Lelej, Storozhenko & Kurzenko, 2006  , nomen nudum

In 2000 N.F. Pashtshenko began publishing a series of papers dedicated to aphids of the genus Uroleucon Mordvilko, 1914  from the Russian Far East. As she writes in the first publication: “The results of the study of the genus Uroleucon  will be presented in a series of three papers; the first and second papers dealing with the subgenera Uroleucon  s. str., Divium subgen. n., and Lambersius Olive  , and third paper with the subgenus Uromelan Mordv.  ” ( Pashtshenko, 2000). However, only the first two works were published ( Pashtshenko, 2000, 2001), and the third article dedicated to the subgenus Uromelan  never saw the light for reasons unknown to me. However, Pashtshenko wrote "sp.n." on the labels of those species that she was going to describe in this article as new to science, and sent some of these slides with paratype designations to Dr. G. Remaudière for the collection of Muséum national d'Histoire naturelle. She labelled one of these species Uroleucon (Uromelan) lehri  , in honor of her husband, the eminent Russian entomologist P.A. Lehr. Slides prepared by Pashtshenko are stored in the collection of the Institute of Biology and Soil Science FEB RAS, where she worked. When after the death of Lehr an article was prepared dedicated to his memory (Zaitsev et al., 2006), the name “ Uroleucon (Uromelan) lehri  ” was included in the list of species described in honor of P.A. Lehr, based on labels on the slides of Pashtshenko. Since the species was not described, Favret (2013) rightly catalogued it as a nomen nudum.

Ultimate length 111–170 119–134 rostral length / length of 2 nd segment of hind tarsus 0.81–1.17 0.83–0.96 segment

length of base of last antennal segment 0.65–0.82 0.58–0.70

number of accessory setae 4–5 4–6 Length of hind femura 711–995 832–944 2 nd segment of hind length 109–161 129–157 tarsus length / length of base of last antennal segment 0.69–0.87 0.63–0.80 Setae on number 3–5 4–6 tergite length 43–63 41– 61 VIII length/ articular diameter of 3 rd antennal segment 1.21–1.91 0.86–1.26 Length of siphunculi 410–774 460–521 Length of distal polygonal reticulation on siphunculi/length of siphunculi 0.20–0.27 0.21–0.26 4 — after Hille Ris Lambers (1939), Heie (1995), Lampel (1980) and materials from collection of Zoological Institute RAS (14 apterous viviparous female from Murmansk Region, Russia).

I have examined all slides from the collection of the Institute of Biology and Soil Science FEB RAS and collection of Muséum national d'Histoire naturelle that contain individuals designated by Pashtshenko as holotype and paratypes of U. lehri  . Samples Nr 4091 and 4163, on the basis of which Pashtshenko was going to describe U. lehri  , were collected respectively on 14 and 24 June 1981 to the southeast of the peak Aborigen in the Tenkinskiy district of Magadan region, on Astrocodon kruhseanus Fed.  (= Campanula expansa Rudolph  ). In the first case, the dark brown aphids were located in the upper part of the plant, and in the second case the aphids were brown-black and black and fed on the stem. There are only 5 apterous viviparous females on the slides; 3 in sample Nr 4091 and 2 in sample Nr 4163.

As can be seen from a comparison of morphometric data ( Tabl. 5) specimens labelled by Pashtshenko with the name “ lehri  ” are practically indistinguishable from Uroleucon (Uromelan) campanulae (Kaltenbach, 1843)  and therefore should be attributed to this species.
