Gibbasilus centrolobus   Londt, 1990b: 15. figs 4 (wing), 24-27 (♂ terminalia).

Description.

The species was described by Londt (1990), based on a unique holotype ♂ specimen, and both the wing and ♂ terminalia were well illustrated. On re-examination it has been found that two paratypes of arenaceus   , 1♀ and 1(sex unknown) lacking terminalia, listed below, were not conspecific and have been reallocated to centrolobus   . The ♀ ovipositor (which is glued to the pin beneath the specimen) is here illustrated (Fig. 8), its length : depth ratio = 3.6 : 1. These specimens appear to be correctly allocated to centrolobus   as the wings are microtrichose and the only pale mystacal macrosetae are restricted to the epistomal margin. The ♂ of this species cannot be confused with other species as it has distinctive terminalia.

Material examined.

SOUTH AFRICA: 1♂ holotype "Clan William [c. 32°12'S, 18°54'E 165 m] / ix-1928 / Dr. Brauns" ( NMSA)*; 1♀ 1? (paratypes of arenaceus   ) "Van Rhyn's, - / Pass [c. 31°23'S, 19°01'E 620 m], 4-5 11'33 / G. van Son" ( NMSA)*.

Distribution (Fig. 20A), phenology (Table 1) and biology. With the transfer of two specimens from arenaceus   to centrolobus   the species is now known from two localities. Collected in September and November. No biological information is available.
