The genus Teissierella was proposed by Monard (1935a: 24) to accommodate a new species T. celtica Monard, 1935a, which he regarded as “transitionary” between Robertsonia Brady, 1880a and Amphiascus Sars, 1905a. He also believed Stenhelia knoxi Thompson & Scott, 1903 and, with reservations, Amphiascus bulbifer Sars, 1911a (now in Haloschizopera Lang, 1944), Stenhelia irrasa A. Scott, 1902 and Dactylopus propinquus T. Scott, 1894a (both now in Robertsonia) could be referred to this genus. Monard’s (1935a) expression “n. g. n. sp.” applied to Teissierella celtica effectively designates this species as the name-bearing type of the genus (ICZN Art. 68.2.1). In the same year Monard (1935b: 26) added the new species, T. salammboi and described a second taxon under the name “T. irrasa (A. Scott) var.”. In a footnote (p. 27) he stated that Teissierella (with two egg-sacs) could turn out to be a synonym of Robertsonia if Sars’s (1909b: 335) assertion of the presence of only one egg-sac in Robertsonia tenuis Brady, 1880a were proved wrong. Sewell (1940: 286) discussed the relationships between both genera and described a new species Teissierella adduensis Sewell, 1940.
Lang (1944: 14) listed Teissierella as a junior synonym of Robertsonia and in his monograph (Lang 1948: 638) considered both T. celtica and T. salammboi as species incertae sedis in Robertsonia, the former as being possibly conspecific with Robertsonia knoxi (Thompson & Scott, 1903), the latter as a potential member of the genus Diosaccopsis Brian, 1925a. Monard’s (1935b) Teissierella irrasa var. was regarded as conspecific with Robertsonia angolensis (Monard, 1934). Krishnaswamy (1957: 51) assigned T. adduensis to Robertsonia, albeit without any factual justification, but this course of action has now been validated by Wells and Rao (1987: 99).
Following Roe’s (1958: 248) redescription, the type species Teissierella celtica is now formally considered a valid species of Robertsonia (Hamond 1973c: 433; Wells 2007: 25). Despite Teissierella thus being a junior subjective synonym of the latter, two new species have subsequently been added: Bodin (1964: 157) described T. massiliensis Bodin, 1964 while Apostolov (1968: 400) added T. pontica Apostolov, 1968. The latter was subsequently considered a junior subjective synonym of Robertsonia knoxi (Thompson & Scott, 1903) by Apostolov and Marinov (1988: 151).
The latest state of affairs was summarized by Wells (2007: 25) who listed Teissierella as a genus incertae sedis in the subfamily Diosaccinae (Miraciidae), containing T. salammboi, T. massiliensis and T. pontica. Since the type species is not included (see above) a new generic name is required for this orphaned grouping. Teissierella salammboi Monard, 1935b is here fixed as the type of the new genus Monardius gen. nov. (in memory of Dr André Monard; gender: masculine) which contains the following new combinations: Monardius salammboi (Monard, 1935b) comb. nov. [type] and M. massiliensis (Bodin, 1964) comb. nov. Apostolov’s (1968: 400–401) description of T. pontica shows that this species cannot be placed in Monardius (e.g. antennary exopod 2-segmented; leg 1 exp-3 with 5 elements and endopod 3-segmented; endopodal armature of legs 2–4; form of setae on leg 5 etc.); in addition, Wells (2007: 550) pointed out that Apostolov (1968: Tafel 3) showed two inner setae on the middle exopodal segment of legs 2–4 which is, if proven correct, a character not found in any other copepod (Huys and Boxshall 1991: 23, 28). Apostolov and Marinov’s (1988: 151) generic assignment is adopted here with the caveat that T. pontica is not necessarily a synonym of R. knoxi; pending re-examination of the type material it is best regarded a species incertae sedis in Robertsonia. In order to satisfy the provisions of ICZN Art. 13.1 a generic diagnosis is given below summarizing the characters that are purported to differentiate Monardius from other genera in the Miraciidae.
