Description

Eusynaptomyces enochri Scheloske

MB#330757

Fig. 3A

Parasitologische Schriftenreihe 19: 110 (Scheloske 1969). –

Type: “Auf den Vorderbeinklauen der Männchen und der Unterseite des Halsschildvorderrandes der Weibchen von Enochrus affinis, E. coarctatus. Eine Form. die etwas von der auf den Klauen lebenden abweicht, fand ich an den entsprechenden Körperstellen bei E. testaceus (Col. Hydrophilidae). Die Wirte stammen aus einem Weiher bei Dechsendorf/Erlangen. Holotypus Abb. 20”. [Germany]

Diagnostic features

[Reduced form] Receptacle consisting of up to five cells. Appendage basal cell (above cell VII) extending into one lateral outgrowth (Fig. 3A, arrow). [Detailed descriptions: Majewski 1994b; Santamaria 2003]

Distribution and hosts

On Enochrus (Col. Hydrophilidae) from Germany (type), Poland (Majewski 1990b), Portugal (Santamaria 1999), and Belarus (Majewski 2008).

Collections examined from Denmark

On Enochrus coarctatus (Gredler, 1863) (Col. Hydrophilidae)

Remarks

First record from Denmark. According to Majewski (1994b), thalli of this species are differentiated into two forms which are seemingly related with the host surface points undergoing contact through mating behaviour (Scheloske 1969); the form B between the claws of tarsi of both anterior legs in male insects, and the form A or normal form under the right anterior margin of female pronotum. We have only found the claw form that is regarded to be more frequent (Majewski 2008). Such reduced forms (see also Autoicomyces humilis) pose true taxonomical problems. Moreover, the monotypic genus Phurmomyces has been questioned as a probably similar growth form of Ceratomyces (Tavares 1985).
