Caccomolpus laticollis (Broun, 1893) , comb. nov.

Aphilon laticollis Broun, 1893a: 392 . Type locality: Thames.

Comments. Broun based the description of this species on a single specimen which we located in the BMNH and confirmed as the holotype. He did not mention the sex nor did he include his typical numbered species. This species is transferred to Caccomolpus because of the form of the subcoxal lines on abdominal ventrite 1 which are convex and form a broad axillary space. This species is considered a synyonym of Caccomolpus globosus by M. Daccordi (pers. obs.), but a full revision of the species is needed before formal synonymy is actioned.

Type examined. Holotype ( BMNH): re-pointed with cleared abdomen and female terminalia in media on separate acetate card [right mid-tarsus and right hindleg missing], “3015.
