Description

Mycteroptids were medium-sized to fairly large. Their outer surface had numerous scales and reticulate ornamentation. Their first and possibly second tergites (dorsal surfaces of the abdominal sections) were strongly developed. Their legs resembled those of Stylonurus. The prosoma (head) was subtrapezoid, with small compound eyes.[1]

Classification

The three genera included in the Mycteroptidae, Mycterops, Woodwardopterus and Megarachne might represent different ontogenetic stages of each other based on the sizes of the referred specimens and the patterns of mucronation. This would sink the genera Woodwardopterus and Megarachne into Mycterops.[2]

Mycterops whitei is a fragmentary species that might not be referrable to the genus at all if more complete specimens show that it has a caudal postabdomen.[2]

Species

The species currently seen as valid species of the genus are:[3]

gollark: Idea: rewrite minoteaur again in clojure.
gollark: Alternatively, what if 1-based but 0 is removed completely from the language?
gollark: I have a better compromise. 0-basd arrays, but with index 1 removed.
gollark: Most languages DO NOT have to CARE about low level details that much.
gollark: Bee you.
