C o m m e n t: The original description of D. jebusaea is based on two syntypes ("Deux individus" from " Jérusalem " ( SAULCY 1865a). Neither of these syntypes was found in the collections of the MNHNP and the IRSNB, so that they must be regarded as lost. In view of the similarity of Dinusa species and the previous taxonomic confusion in the genus, a neotype designation is necessary to stabilize the name D. jebusaea .

Dinusa particeps was described from an unspecified number of syntypes, possibly a single specimen, from "Béthel" ( ABEILLE DE PERRIN 1896). One syntype, a female, was located in the Fauvel collection. This specimen is designated as the lectotype.

According to ABEILLE DE PERRIN (1896), D. particeps is distinguished from D. jebusaea by a pronotum of paler coloration and with sparser punctation. However, a comparative

study of the external characters of the lectotype of D. particeps and of material identified as D. jebusaea yielded no clear-cut differences; the coloration and the punctation of the pronotum are subject to some variation in D. jebusaea , as well as in Dinusa species in general. Moreover, the shape of the spermatheca is identical. Consequently, there is little doubt that both names refer to the same species. In order to stabilize this synonymy, the lectotype of D. particeps , which was collected close to the original type locality of D. jebusaea , is designated as the neotype of D. jebusaea , thus rendering the synonymy of both names objective.

Dinusa jebusaea is distinguished from the sympatric D. hierosolymata particularly by the shorter antennae (antennomeres VII-X transverse; Fig. 42 ), the much smaller and differently shaped median lobe of the aedeagus ( Figs 43-44 ), and by the much longer and differently shaped proximal portion of the spermathecal capsule ( Figs 45-47 ). It differs from D. angulicollis by the shape of the pronotum (posterior angles not marked; Figs 40-41 ).
