Candanius gracillimus (Candéze) comb. n. 
Anitus gracillimus Candéze, 1889 : 103. 
The description is based on an unrecorded number of specimens from Chile 
submitted by Fairmaire. Fleutiaux (1907: 170) described the three specimens 
in the Candéze collection in the IRSNB, Brussels in some detail. He tentatively, 
but correctly, identified them as two males and one female but expressed some 
doubt that they belonged to the same species. I believe that they may be 
conspecific. As Fleutiaux remarks, it is impossible to tell which specimen formed 
the basis of Candéze’s description. For the present I consider that all three 
specimens should be treated as syntypes and they have been labelled to this effect. 
Syntypes examined. CHILE: 9, Anius n.g. gracillimus Cand. Chile [?Fairm.]; 
ex coll. Fairmaire; Collection E. Candéze; Anius gracillimus Cand. 9? Fleutiaux 
det. 1903 [Fleut.]; Anius gracillimus Cd. det. E. Candéze [IRSNB curatorial label].

Candéze placed Anius in the sub-tribe Pomachilites near Psilonicus. However 
all three specimens differ from Psilonicus and its allies in that tibial spurs are 
absent, the claws bear setae at the base and the prosternopleural suture is grooved 
for a greater (9, groove occupies about half the length of the suture) or lesser 
(g, groove occupies slightly less than one third of the length of the suture) part 
of its length for the accommodation of the antennae. I believe that the presence 
of these characters fully justifies the inclusion of gracillimus in the Agrypninae. 
Fleutiaux (1907 : 170) was of the same opinion as he considered that the genus 
should be placed near Adelocera [sensu auct. nec Latreille, =Lacon Castelnau 
of the present work]. 
In general appearance and the possession of short antennal grooves C. gracillimus 
bears a distinct resemblance to the chilean Dilobitarsus vitticollis (Fairmaire and 
Germain) and D. crux (Philippi). It differs from these species in that there are 
no lobes on the tarsi. It is of interest that C. gracillimus resembles D. vitticollis 
and crux in that the prothorax of the female is much more strongly convex than 
that of the male and I consider that this lends support to my belief that the 
syntype specimens are conspecific. It must be admitted that in no other species 
known to me does the length of the antennal groove of the female differ from that 
of the male. Fleutiaux’s (1907: 167) comment that this difference occurs in 
vitticollis is based on the erroneous synonomy of D. vitticollis and D. crux. 
For the present the genus Candanius is retained as a separate entity. Study 
of additional material, when it becomes available, may show that (as in the case 
of Agrypnus) the structure of the tarsi and the length and depth of the groove 
for the accommodation of the antennae are not characters of sufficient impor- 
tance to justify the retention of Dilobitarsus, Lacon and Candanius as separate 
genera.
