Condición: 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 espèces du genre Pachybrachis se caractérisent par une très grande variabilité intraspécifique des taches jaunes ou noires, y compris au sein d'une même population. Cette variabilité impose l'examen systématique des genitalia mâles et femelles. Si l'étude des génitalia mâles a fait l'objet de plusieurs travaux notamment ceux de Burlini et Warchalowski, la détermination des femelles isolées était pratiquement impossible. Le présent ouvrage propose pour la première fois un dessin des spermathèques de toutes les femelles des espèces de France ainsi qu'une photographie et un dessin de tous les édéages mâles. 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.
