Distribution. USA (AZ, CA), Mexico (BC, BCS, SIN).

Diagnosis. Adults. General coloration dark; ocular rim with short setae projecting over the eye; labial palpi with distal palpomere greatly swollen; procoxae and profemur with many clavate, clustered white setae; male ectoproct with a very short, almost unnoticeable postventral lobe; gonarcus narrow, slightly twisted on lateral margins; paramere plates sclerotized ventrally; paramere teeth basally not expanded; paramere teeth slender, elongated, slightly curved and pointing posterodorsally; female ectoproct with short digging setae; lateral gonapophysis small, with short digging setae; posterior gonapophysis greatly swollen, with many long hairlike setae; anterior gonapophysis plate-like, with many long hairlike setae; pregenital plate membranous.

Remarks. At first look, G. barberi resembles a dark species of Chaetoleon , however it may be readily diagnosed by its large and welldeveloped tarsal claws and tibial spurs, as well as a swollen distal labial palpomere. It may be further identified by the large number of clustered clavate setae on the profemur, a unique trait among all Brachynemurini . This species was already recorded from Baja California ( Stange, 1970), yet this is the first record of the species for Baja California Sur.
