Figure 11 in The Miocene tortoise Testudo catalaunica Bataller, 1926, and a revised phylogeny of extinct species of genus Testudo (Testudines: Testudinidae)
Figure 11. Results of the cladistic analysis, as depicted by the single most parsimonious tree. Numbers above clades represent bootstrap values, and numbers below clades are Bremer indices; node numbers are used to summarize clade apomorphies in Table S1. Type species of each subgenus are denoted with an asterisk, and extinct species with a dagger.
Figure 10 in The Miocene tortoise Testudo catalaunica Bataller, 1926, and a revised phylogeny of extinct species of genus Testudo (Testudines: Testudinidae)
Figure 10. Detailed schematic drawings of neural plate 1 in dorsal view of Testudo (Chersine) catalaunica from the Valles-Penedes Basin compared with those of selected representatives of Testudo s.l. and Indotestudo. Thick solid lines correspond to scute sulci (the posterior sulcus of vertebral 1), whereas dotted lines denote plate sutures (of neural 1 and surrounding plates); thinner solid lines and areas with oblique lines denote damaged or missing shell portions. (A, B) Testudo (Chersine) catalaunica MGSB31642 (A) and IPS30073 (B); (C) Testudo (Chersine) steinheimensis SMNS 80200; (D) Testudo (Chersine) pyrenaica UCBL1 92865; (E) Testudo (Chersine) lunellensis IPS57549; (F) Testudo (Chersine) antiqua SMNS 4450; (G) Testudo (Chersine) burgenlandica NMW 1981/24/1; (H) Testudo (Paleotestudo) canetoniana SA 1857; (I) Indotestudo elongata MNHN.REP64; (J) Testudo (Testudo) graeca MNHN.REP66; (K) Testudo (Testudo) marginata MNHN.ZA1877.675; (L) Testudo (Testudo) kleinmanni MNHN.ZA1876.416; (M) Testudo (Agrionemys) horsfieldii MNHN.REP51; (N) Testudo (Chersine) hermanni MNHN.REP9.
FIGURES 1–6. Semanopterus kingstoni new species, holotype. 1 in A new, but possibly extinct, species of Semanopterus Hope, 1847 from Lord Howe Island, in the southwestern Pacific Ocean (Coleoptera: Scarabaeidae: Dynastinae)

FIGURE 5. Comparative material. a in A new species of Lethrinops (Cichliformes: Cichlidae) from a Lake Malawi satellite lake, believed to be extinct in the wild
FIGURE 5. Comparative material. a. Three small specimens (BMNH 1935.6.14.2077-9) from Lupembe in northern Lake Malawi match Lethrinops lethrinus, in melanin pattern and low position of mouth on the head. b. A syntype of Lethrinops leptodon BMNH 1921.9.6.201-207, showing two oblique stripes thickened and fused together to form a midlateral blotch. This pattern is distinguishable from those of L. chilingali and L. lethrinus, but is similar to the Nkhata Bay population reported by Eccles & Lewis (1978) and assigned by them to L. lethrinus.

FIGURE 1. Geometric morphometric analyses of Lethrinops lethrinus and Lethrinops chilingali a. Landmarks used to quantify shape variation of preserved specimen (see Materials and methods for details). b. Principal Component Analysis indicates strong separation of L. lethrinus and L. chilingali on PC1, with clear differentiation of the respective holotypes. c. Wireframe plots of mean body shapes of L. lethrinus (blue) and L. chilingali (orange), showing the more ventrally placed mouth, longer snout, and higher back in specimens of L. lethrinus relative to L. chilingali.
