Scaberiloricus is a monospecific genus, with its only species being Scaberiloricus samba.
Taxonomy
[edit]Scaberiloricus samba was found using the craft R/V1 Ocean Stalwart. It collected samples from northwest to southeast. It traveled sideways to the continental shelf of Brazil, between São Sebastião and Rio de Janeiro.[1]
To discover the relationships and species of the specimens found, scientists analyzed it along with 25 other species' Higgins-larvae.[1]
Etymology
[edit]Scaberiloricus comes from the Latin scaber-, meaning "rough" and Latin -loricus, meaning "lorica". The name refers to the zigzagged rugae seen in the thorax.[1]
Traits
[edit]The features of adults are unknown.[1]
Higgins-larvae
[edit]Some features of this species' Higgins-larvae include:
- Small rounded heads, the front of which are smooth, while the back sides have multiple folds, except for areas with scalids.[1]
- A compressed area behind the head.[1]
- A lengthy trunk2.[1]
- Eight rows of scalids.[1]
- Mouth cone including eight indented lines and teeth.[1]
- Thorax has over 40 zigzagged folds.[1]
- Abdomen with around 20 straighter folds. The abdomen is very slightly shorter than the thorax.[1]
- Of the frontal hair-like structures, one pair is abdominal, while the other is found on the sides.[1]
- Lengthy, thin toes with tips pointed away from the body. The toes are supported by plates connecting them to the body.[1]
Scalid rows
[edit]Notes
[edit]^1 R/V stands for Research Vessel.[2][3]
^2 In the phases between molts, the trunk has a similar width to the head.[1]
^3 Rows start counting from the inside to the outside, and are found on the introvert.[1]
