Cyrtodesmus depressus
''Cyrtodesmus depressus'' is a species of millipede in the family Cyrtodesmidae that can be found in San Vito, Costa Rica, where it was found on 17–18 April 1972 by Harold F. Loomis.
==Description==
The males of the species are long and wide, while females are a bit bigger. The convex of dorsum is moderate. Their metazonites and keels are dirty but not everywhere. The tubercles is one of such examples, which also have a shining area. The first segment is almost hidden by the second one, with segments 3-17 are flaring outward. The second segment have keels which are expanded. Their margins aren't lobed and therefore are not undulated either. Segment 15 is almost straight and has no visible marginal lobes. The last segment has 2 tubercles which are submedian.〔
The gonopods look a lot like in ''C. hispidulosus'', with the only 2 differences; the current species doesn't have spicules and have limited organic coating. It is also have a hidden outer joint, with a lateral surface and large tubricle which is also rounded. They also have 2 small and transverse tubercles which are located on their sternum of their ninth row of legs. It has a large anterior marginal lobe which is located on each angle from the outside. Their surface is quite swollen from both sides and covered with tubercles which are sharp and conical in shape. The tubercles themselves are small, low, are poorly defined, and ain't numerous. The species also have 3 tubrcles with blunt ends. Their dorsum convex have a broad and joint coxal, which is ventral and is a little higher than the coxae of the adjacent legs. The females have a nearly straight ventral crest on the third segment which is rising from the sides. ''Cyrtodesmus depressus'' have identical to C. dentatus supplementary margin.〔
