FIGURE 3 in Rediscovery, taxonomic status, and phylogenetic relationships of two rare and endemic snakes (Serpentes: Psammophiinae) from the southwestern Angolan plateau
FIGURE 3. Psammophis ansorgii NB 560, Tundavala montane grassland, Huíla province; A: whole body dorsal coloration showing the characteristic reddish brown body; B: Lateral view of head showing scalation and distinctive ivory-coloured pre- and postoculars and dark-edged, pale upper labial stripe; C: Habitat—montane grasslands, Tundavala, Huíla Province; D: Illustration from Boulenger's (1905) description of P. ansorgii showing uniform body coloration, and pale upper labial stripe and pale pre- and postoculars. All photos by N. Baptista.
FIGURE 2 in A phylogenetic analysis of Neotoma varia (Rodentia: Cricetidae), a rediscovered, endemic, and threatened rodent from Datil Island, Sonora, Mexico
FIGURE 2. Phylogenetic trees of the 828-bp fragment of the Cyt b gene generated from the analyzed Neotoma specimens. The numbers of haplotypes and subspecies at the tip of each branch follow Table 1. The trees were constructed using the 50% majority rule consensus algorithm (except in maximum-likelihood). Values in the nodes are branch support for the analyses. The N. leucodon sequence was included as the ingroup and N. picta, N. isthmica, and N. mexicana as the outgroup. (A) Maximum-likelihood tree using the GTR+I model; (B) neighbor-joining tree, genetic distances were calculated using the Jukes-Cantor model, percentage differences per node are in table 2. (C) Bayesian inference performed using the GTR+I model.
Fig. 10 in Larval Description and Phylogenetic Placement of the South African Endemic Genera Coelhydrus Sharp and Darwinhydrus Sharp (Coleoptera: Dytiscidae: Hydroporinae: Hyphydrini)
Fig. 10. One of the most parsimonious trees obtained from the cladistic analysis of nine terminal taxa of Hydroporinae, with character changes mapped for each clade (using ACCTRAN optimization). Solid rectangles indicate unique character state transformations; open rectangles indicate homoplasious character state transformations. Numbers outside parentheses are characters listed in Table 3; numbers within parentheses are character states as given in Table 3.
Figs. 7–8 in Larval Description and Phylogenetic Placement of the South African Endemic Genera Coelhydrus Sharp and Darwinhydrus Sharp (Coleoptera: Dytiscidae: Hydroporinae: Hyphydrini)
Figs. 7–8. Darwinhydrus solidus, instar III, metathoracic leg. 7) Anterior surface; 8) Posterior surface. Scale bar = 0.50 mm.
Figs. 1–2. Coelhydrus brevicollis, instar III. 1 in Larval Description and Phylogenetic Placement of the South African Endemic Genera Coelhydrus Sharp and Darwinhydrus Sharp (Coleoptera: Dytiscidae: Hydroporinae: Hyphydrini)
Figs. 1–2. Coelhydrus brevicollis, instar III. 1) Head capsule, dorsal view; 2) Abdominal segment VIII and proximal portion of urogomphi, dorsal view. Scale bars = 0.50 mm.
FIGURE 19 in Larval morphology of the Madagascan endemic diving beetle genus Hovahydrus Biström, 1982 (Coleoptera: Dytiscidae) and phylogenetic comparison with other known Hyphydrini
FIGURE 19. Single most parsimonious cladogram obtained from the cladistic analysis, with Bremer (in bold) and Bootstrap (higher than 50) support values indicated above branches. Character changes are mapped for each clade, with numbers in bold underlined indicating unique character state transformations. Hovahydrus sp. near H. minutissimus (Régimbart, 1903) is abbreviated to Hovahydrus n.sp. in the cladogram.
