Condizione: New. 50, 16 col plates, figs. . PB. NEW. . Text French. Identification key, with species descriptions and distributions. This genus is characterised by high intraspecific variability within the same populations. This variability requires the examination of male and female genitalia for species identification. Study of the male genitalia has been the subject of several works, including Burlini and Warchalowski, however, determination of isolated females has been virtually impossible until now. This book presents for the first time drawings of the spermathecae of females for all the species known from France as well as photographs and drawings of all male aedeagi.…

Identification key, with species descriptions and distributions. This leaf beetle genus is characterised by high intraspecific variability within the same populations. This variability requires the examination of male and female genitalia for species identification. Study of the male genitalia has been the subject of several works, including Burlini and Warchalowski, however, determination of isolated females has been virtually impossible until now. Les Pachybrachis de France presents for the first time drawings of the spermathecae of females for all the species known from France as well as photographs and drawings of all male aedeagi. Les esp?ces du genre Pachybrachis se caract?risent par une tr?s grande variabilit? intrasp?cifique des taches jaunes ou noires, y compris au sein d une m?me population. Cette variabilit? impose l examen syst?matique des genitalia m?les et femelles. Si l ?tude des g?nitalia m?les a fait l objet de plusieurs travaux ? notamment ceux de Burlini et Warchalowski, la d?termination des femelles isol?es ?tait pratiquement impossible. Le pr?sent ouvrage propose pour la premi?re fois un dessin des spermath?ques de toutes les femelles des esp?ces de France ainsi qu une photographie et un dessin de tous les ?d?ages m?les. 49 pp., 7 plates with 24 color photos; 47 color & b/w photos and b/w line drawings, 22 b/w distribution maps, paperback 4.…
