Stem width 60 μm in diameter, in cross section with 7(‒8) cortical cells and 6‒7(‒8) medullary cells. Ventral merophytes two cells wide. Leaves spreading, contiguous to imbricate; lobe ovate, slightly falcate, 290‒340 μm long × 240‒280 μm wide, dorsal margin arched, smooth, ventral margin slightly arched, forming an angle with keel, smooth, apex rounded; basal cells oblong, 30 μm long × 15 μm wide, median cells oblong, 20 μm long × 13 μm wide, thin walled, trigones large, intermediate thickenings occasional; mostly 2‒3 coarsely segmented oil bodies per cell, in young leaves oil bodies completely filling the cell lumen (noted for paratypespecimen 13499); ocelli absent; lobule ovate, strongly inflated, 160‒200 μm long × 100 ‒ 120 μm wide, free margin involute to plane composed by elongate cells, second tooth elongated, hyaline, spinulose, hyaline papilla at distal base of second tooth, apical margin oblique, involute, keel arched, smooth to slightly crenulate. Underleaves small, (120‒)130 ‒ 180 μm long × (100‒)130‒140 μm wide, distant, orbicular to ovate, bifid to 1/2, sinus acute, base cuneate, insertion line curved. Androecia apical or on lateral branches, 2‒4 pairs, bracteole at base of the branch. Gynoecium terminal, innovation pycnolejeuneoid, lobe bracts obovate, 400 μm long × 300 μm wide, margin entire, bracteole bifid, oblong, 490 μm long × 230 μm wide, margin entire, perianth obovate, 690 μm long × 420 μm wide, rostrum long, 60 μm long × 50 μm wide. Additional material examined:―  BRAZIL. Santa Catarina, Passstraβe Urubici-Grão Pará, an sickerfeuchtem Felswenig unterhalb der Passhöhe,  1110 m, 28°00’S, 49°21’W,  30 Dec. 1990,  Schäfer-Verwimp& Verwimp13499( ALCB; SP; hb. Schäfer-Verwimp).   Etymology: The specific epithet refers to the similarity with members of  Cheilolejeuneasect. Cyrtolejeunea(Evans 1903: 533) Ye, Gradstein & Zhuin Ye et al. (2015: 324).   Distribution and ecology: The new species seems to be restricted to the South and Southeast Brazil. Unlike other recently described species for Brazil, which were from Bahia(  C. lacerata Bastos et Gradstein (2006: 133),  C. ornata Bastos (2011: 86)), Minas Gerais(  C. laciniata Peralta & Reiner-Drehwald (2013: 54)), and Amazonas (  C. amazonica Bastos & Zartman (2016: 15)), this is the first species described from Espírito Santoand Santa Catarina.  Cheilolejeunea cyrtolejeuneoidesis growing on humid shady rocks which may be sometimes irrigated, in low woody vegetation along a stream ( holotype) and on shady rocky slope at roadside ( 13499) between 1100 and 1850 m.a.s.l. In the holotypecollection several plants of  Neurolejeunea breutelii(Gottsche in Gottsche et al. 1845: 324) Evans (1907: 13) are admixed beside a few plants of a small  Plagiochilaand a single young plant of  Rhodobryum. The plants of the paratypecollection are growing on and between  Riccardia regnelli( Ångström 1876: 90) Hell (1969: 110)and a species of cyanobacteria (cf.  Schizothrix); a few plants of  Harpalejeunea subacutaEvans (1903: 547)(c. per.) could also be found. 1987-07-26 JE, ALCB, SP Schafer-Verwimp & Verwimp Brazil Type 1850 Serra de Caparao Brazil 1 67 2 Espirito Santo holotype 1990-12-30 ALCB, SP der Passhohe & Schafer-Verwimp & Verwimp Brazil 1110 -28.0 Fels 1234 -49.35 Urubici-Grao 1 67 1 Santa Catarina
