Figure 1 in Molecular systematics of peppermint and cleaner shrimps: phylogeny and taxonomy of the genera Lysmata and Exhippolysmata (Crustacea: Caridea: Hippolytidae)
Figure 1. Phylogenetic tree obtained from Bayesian inference (BI) analysis of the partial 16S rRNA gene for shrimps from the genus Lysmata, and other selected taxa from the Caridea. Numbers above or below the branches represent the posterior probabilities from the BI analysis and bootstrap values obtained from maximum likelihood (ML) in PAUP* (BI/ML). The white and black squares represent the presence or absence, respectively, of a developed accessory branch in each species. The images of the shrimps (from top to bottom) represent Lysmata wurdemanni, Lysmata grabhami, Lysmata intermedia, and Lysmata hochi.

Figure 13 in Molecular taxonomy reveals an overlooked cryptic species of the tiger moth genus Murzinowatsonia Dubatolov (Lepidoptera, Arctiinae) from Sichuan, China
Figure 13. (a) Chronogram of the multilocus species tree showing estimates of divergence times obtained through the Bayesian dating analyses with BEAST v.2.6.3.0. Horizontal blue bars represent the 95% HPD heights for the major nodes of the chronogram. Numbers at nodes are median ages for the divergence times in Myr. A 5 Myr-timescale is placed at the bottom of the chronogram; (b) DensiTree v. 2.01 visualisation of the multilocus tree sample implemented in BEAST v.2.6.3.0. Gold stars at the corresponding nodes indicate the calibration points used to ultrametrize the topology: a secondary calibration at the stem of Arctiinae and a fossil at the crown of the clade Arctiina +Spilosomina. For the fossil calibration, a picture of the fossilized fore wing of Stauropolia nekrutenkoi Skalski, 1998 retrieved from; Skalski (1988) is presented at the crown of Arctiina+Spilosomina.
