Fig. 33E–H
Sterbeeckia 18: 17 (De Kesel 1998). –
Type: “ HOLOTYPUS: De Kesel 991 (BR), die 28.VIII.1987, in locis Heide Kalmthout (Antverpia, Belgia), ad sternitum abdominalis Dromii linearii (Olivier) (Coleoptera, Carabidae) lectus; BR. [Belgium]
Diagnostic features
Cell V oval, slightly shorter than cell IV, not connected with cell III; its inner margin separated from perithecium at least in its distal portion. Insertion cell separated from perithecium. Outer appendage unbranched, brown. Inner appendage once divided above the basal cell, consisting of two simple, hyaline branches, both terminated by solitary, poorly distinguished antheridia. Basal cell of inner appendage much smaller than basal cell of outer appendage. Perithecium bearing a long ligula-like lip.
Distribution and hosts
This species grows hidden near or on the pygidium of Paradromius Dejean, 1826 (often as Dromius) (Col. Carabidae) from Belgium (type), Latvia (De Kesel & Krastina De Kesel 2006), United Kingdom (Lazenby 2017), Sweden and Canary Islands (Huggert 2010).

Remarks
First record from Denmark.A photo of this species is given here for the first time. Laboulbenia hyalopoda often coexists with L. notiophili on the same host and could be suspected as a growth-form, although no morphological variation has been observed in the latter species when growing on less suitable places. We consider L. hyalopoda a good species with striking morphological characteristics. Molecular analysis has been suggested to confirm its distinctiveness by De Kesel et al. (2020). Laboulbenia hyalopoda grows on a very specific position of host, near the copulatory apparatus, and its transmission between hosts seems evidently correlated with mating behaviour. The foot is pale, appearing to have a lateral attachment demonstrated by the presence of dark rings (Fig. 33H, arrows).
