RECLASSIFICATION OF SUBFAMILY AGRYPNINAE gI 
1903.130; Eidolus linearis Cdze, type. [Janson] ex coll. Laferte [Gahan]; Hem. 
agrestis Buq. in mus. e coll. de Laferte [Janson] (BMNH). 
The absence of Candéze’s determination label is probably due to Janson (see 
p. 276). The second syntype, from the Deyrolle collection, has not been located. 
OPATELUS Candéze 
Opatelus Candéze, 1857: 86. Type-species: Opatelus limbatus Candeze, by subsequent 
designation (Hyslop, 1921 : 660). 
GENERIC DIAGNOsIS. Each claw bearing a group of setae near the base (Text-fig. 11) 
Tibial spurs absent. Mesepisternum, does not form part of the margin of the mesocoxal cavity; 
mesepimeron forms part of the margin of the mesocoxal cavity (Text-fig. 3). Second and third 
antennal segments subequal, each smaller than the fourth and following segments. Antennal 
groove long, extending almost the entire length of the prosternopleural suture. The distance 
separating the posterior end of the groove from the anterior coxae is equal to the width of the 
groove. The groove is deep enough to accommodate the rolled antennae. Body clothed with 
narrow scales. Prothorax simple, without constriction behind anterior angles; lateral carinae 
present. Propleurae and metasternum with well defined grooves for the reception of the tarsi 
of the anterior and middle legs. Propleural grooves parallel to antennal grooves; metasternal 
grooves curved, running diagonally across the sternite, the posterior ends, if produced, would 
cut the posterior margin of the metasternum near the posterior lateral angles (Text-fig. 4). 
Scutellum simple, without carina. Fourth tarsal segment with a ventral lobe (Text-fig. 16). 
HIsTORY OF THE GENUS. This distinctive and easily recognized genus was 
established for the four species which are still assigned to it. 
Candéze’s generic diagnosis, which except for the first three characters listed, 
agrees remarkably well with that given above, defines the genus so accurately that 
it is very surprising that he subsequently assigned argentatus (see Lacon argentatus 
(Candéze), p. 56) to the genus. 
SEXUAL DIMORPHISM. The sexes are not distinguishable on external 
characteristics. 
DISTRIBUTION. Brazil, Bolivia. 
BIoLoGy AND HABITS. Nothing is known of the habits or life-history of the 
four species included in the genus. 
SPECIES INCLUDED IN THE GENUS 
Schenkling (1925 : 20) records five species in this genus. The generic attribution 
of three species is confirmed by examination of the type-material and a fourth 
provisionally placed on information available from the description. The fifth, 
argentatus Candéze is transferred to Lacon (see p. 56).

Lacon cribvatus Blanchard, 1845 : 145.
