Bohmig L 1895 (citation)- mentions p 43, 45.
Wilhelmi J 1913 (citation)- p 12 does not list but refers to it p 67, 82.
Riedel G 1932 (citation)- includes in key of Macrostominae p 86.
Westblad E 1948 (citation)- penis inverts on use in some species and has a secretory cap.  p 23 brain in
	p 50 notes both separate and combined genital pores in this genus.

Marcus E 1948 (citation)- Discusses relation of Aphanostomum and Mecynostomum and species.  Gives
	key to 11 species of Mecynostomum.  Diagnosis from Westblad "mouth ventral without pharynx; a
	seminal bursa which can be lacking, without a nozzle; external duct (vagina) of bursa can open
	combined with the male copulatory organ or separated from this on the ventral side".[Bush translation].
	this a group of species without nozzles to bursa.
	Reference p 112 and literature review to date.  Key to species 112-113, 
	diagnosis p 112 [Paraconvoluta=this p 112, 187.
Marcus E 1950 (citation)- reproduction p 12, mentions 13, 15, 103.	
Marcus E 1951 (citation)- lists as above, refers also to Westblad E 1948 (citation) p 7.
Marcus E 1954 (citation)- good discussion of history of genus and problems with it- type is 
	M. auritum (M. S. Schultze 1851) but both Meixner and Westblad redescribed as of different species.
	insunk epithelium or not  occurs in this genus.  Divides genus into 2 groups:
		1- combined genital pores-
			M. macrobursalium
			M. minima
			M. pellitum
			M. idium
		2- separate genital pores-
			M. lutheri
			M. evelinae
			M. bathycola
			M. auritum
			M. pulchellum
			M. pallidum
			M. sanguineum
	Further changes suggested- not made M. agile and M. macrospiriferum	to neighborhood of
		Avagina, and M. tenuissimum to Faerlea.		
Steinbock O 1966 (citation)- mentions p 116.
Dorjes J 1968 (citation)- p 117 defines genus and lists 2 species, M auritum (M. S. Schultze 1851) and
	M. haplovarium Dorjes 1968.  Discussion of - literature review.  Westblad E 1946 (citation) did not
	have Schultze's species.  Since he said a bursa seminalis present- he notes Meixner, Ax, Luther
	are correct and agrees with them that Schultze's species lacked bursa seminalis.

Rieger RM 1971 (citation)- mentions p 244.
Henley C 1974 (citation)- sperm are her type 1, p 299 on ultra structure of sperm (Hendelberg J 1969 (citation)).
Tyler S 1979 (citation)- used a specimens of this genus in electron microscopy work.
Rieger RM 1981 (citation)- electron microscopy work on p 216.
