Fig. 41C–D

Bulletin de la Société d’Histoire Naturelle de l’Afrique du Nord 7: 28 ( Maire 1916a). – Type: [Type lost?!] “ Sur les élytres de Tachys bisulcatus Nic. : Larache ( Maroc), marais de Bou-Charren , 4/5 1910 (P. de Peyerimhoff)” .

Diagnostic features

Cell II up to eight times as long as broad, showing a corrugated surface ( Fig. 41D ). Cell V oval, half of the length of cell IV, not connected with cell III. Outer appendage unbranched, straight. Inner appendage consisting of two short branches borne from the basal cell and each giving rise to a solitary lateral antheridium. [Detailed description: Santamaria 1998]

Distribution and hosts

This species seems exclusive on carabids of the genus Porotachys (often as Tachys ) and allied genera of the subtribe Tachyina ; from Morocco (type), Greece ( Balazuc 1974e), Italy ( Rossi 1975), Lebanon ( Huldén 1985), and Spain ( Santamaria 1989). The record from Japan on Macrotachys Kult, 1961 ( Terada 1998a) was unexpected.

Collections examined from Denmark

On Porotachys bisulcatus (Nicolai, 1822) (Col. Carabidae ) DENMARK – Lolland, Falster, Møn (LFM) • Stensø ved Nakskov ; 54°49.465′ N, 11°7.254′ E; PF37; 7 Jan. 2018; JP 950; JP det.; ZMUC C-F-123456 .

Remarks

First record from Denmark. Although the Danish material consists of only one immature thallus, its classification leave no doubt because of the unique characters of cell II (see the corrugation of its margins in Fig. 41D ) and outer appendage.
