Map of valley networks in the northwestern Hellas region, Mars
<p><span>This dataset provides a representation of the valley networks in the northwestern Hellas region. We mapped the valley networks as vector-based polylines within ArcGIS software, using the ~5 m/pixel CTX mosaics with THEMIS daytime IR mosaics as the regional background. Additionally, we used the 200 m/pixel MOLA-HRSC blended DEM for detailed identification, mapping, and derivation of topographic and morphologic parameters of valley networks. The dataset includes the whole valley networks within the study region, the mainstreams of the valley networks, single valleys, and extracted junction angles. Attribute tables are associated with the dataset, providing useful information and morphologic parameters of the valley networks such as length, sinuosity, stream order for each valley networks.</span></p>

Figure 4. Cambarus loughmani sp. nov.; all taken from holotype male, Form I (NCSM 90082), except E and F from morphotype male, Form II (NCSM 90084), and I from allotype female (NCSM 90083): (a) lateral aspect of carapace; (b–d) mesial and lateral aspect of Form I male gonopod; (e–f) mesial and lateral aspect of Form II male gonopod; (g) ventral aspect of epistome; (h) dorsal aspect of carapace; (i) ventral aspect of annulus ventralis; (j) dorsal aspect of the antennal scale; (k) dorsal aspect of distal podomere of right cheliped. Note that the red lining of the rostrum and purpleish hue of the animal during the time of the photo are a byproduct of recent preservation in ethanol and colours in this plate are not representative of those in life.

The tree depicts relationships among Cambarus loughmani sp. nov. (in bold) and several other species formerly considered part of the C. dubius species complex. Also represented are other related burrowing crayfish from the genus Cambarus as well as additional taxa from two other genera that are included as outgroups. Numbers at the nodes of the tree indicate Bayesian posterior probabilities.
