MB#250016 Fig. 29B–C Proceedings of the American Academy of Arts and Sciences 29: 107 ( Thaxter 1894 ) . – Type : “ On Bembidium bimaculatum , Washington (Miss Parker)”; FH . [ USA ] Diagnostic features Cell V oval, as long or longer than cell IV, connected with cell III. Insertion cell not contrasting because it is dark brown like the surrounding cells. Outer appendage unbranched, with similar basal and suprabasal cells, separated with a blackened and constricted septum; upper part of the appendage deteriorating easily with ageing. Inner appendage consisting of a basal cell slightly shorter than basal cell of outer appendage, bearing 1–2 caducous antheridia directly or above its respective supporting cells. Perithecium conspicuously inflated, free, measuring more than the half of the total length of the thallus. [Detailed descriptions: Thaxter 1896 ; Majewski 1994b ; Santamaria 1998 ] Distribution and hosts This species can be found on the legs, especially the tarsi, of Bembidion in a broad sense (Col. Carabidae ) from USA ( type ) and a few countries in Europe ( Spain , Poland , Finland , Sweden , Russia ) ( Majewski 2008 ). Recently recorded from Bulgaria ( Rossi et al. 2019a ).

Although considered a growth form of L. pedicellata and L. luxurians occurring on tarsi by some authors ( Scheloske 1969 ), this conception is questioned because thalli of these two species may be found interspersed with those of L. curtipes ; in such cases all thalli maintain their specific characteristics.
