Eurycorypha listed by Griffini (1908)

Material examined. Democratic Republic of Congo, Kinchassa (2♂ of different species) ( RBINS).

Griffini (1908) reported the males of two unidentified species of Eurycorypha , whose characteristics did not match those of known species; however, he remarked that the description of many species of Eurycorypha was from the female sex, and consequently the above listed males could belong to species known only from females and consequently the above listed males could belong to species described only from the female sex. The opportunity to study the specimens listed by Griffini (1908) allowed to take some photographs of their characters, here presented in Figs 5 and 6 . This will consent in the future to ascertain if they belong to undescribed species or to species already described from the female sex. Recently the male of Eurycorypha flavescens (Walker, 1869) and Eurycorypha klaptoczi Karny, 1917 (both known only from the female sex) were described by Massa (2017b), who obtained a series of males and females collected together.

Characters of the species cited by Griffini (1908) are the following.

Species 1. The stridulatory file is sinuous and consist of ca. 80 evenly spaced teeth. The anal segment has an horizontal compressed process, narrowed on the centre and well enlarged at the apex, where it is obliquely cut; it is vertically furrowed and divided into two short dorsal and two ventral tips. Cerci are broad, stout, up-bent after the centre as an elbow, well compressed and curved, apically obtuse. The subgenital plate is short, apically concave without styli ( Figs 5A, 5B, 5C, 5D, 5E ).

Species 2. The stridulatory file is curved and consists of ca. 90 evenly spaced teeth. The anal segment is attenuated from the base to the apex and ends with two parallel, rather broad, short and down-curved apices. Cerci are long and fine, incurved and pointed. The subgenital plate is rather large, apically concave, with short styliform appendices ( Figs 6A, 6B, 6C, 6D, 6E ).
