Deltochilum (Deltochilum) rosamariae Martínez, 1991

(Figs. 7–8)

Martínez1991: 390 original description (combination: Deltochilum rosamariae )

Type locality. Ecuador, provincia Los Ríos, Quevedo, Pichilingue, XII.1978, A. Martínez.

Distribution. Ecuador.

Material examined (6 males, 15 females). ECUADOR: LOS RÍOS, Estación Experimental Tropical Pichilingue, Quevedo, (1°0'13''S, 79°27'50''W), v.1976, coll. Martínez - 14 females, 5 males (including 19 paratypes) ( CMNC); same locality, iv.1976, coll. Martínez - 1 female (paratype) ( CMNC); same locality, viii.1976, coll. Martínez - 1 male (paratype) ( CMNC).

Remarks. As for D. eurymedon , this species is known only from the original type specimens collected from a single locality. Interestingly, no additional specimens of this species were collected at the Estación Científica Río Palenque located only 50 km north of Estación Experimental Tropical Pichilingue with only a 200 m elevation difference despite extensive dung beetle trapping by H.F. Howden, S.B. Peck and others on several occasions from 1975 to 1979. Externally D. rosamariae is most closely related to D. eurymedon from which it can be separated by its smaller size and the shape of parameres (Figs. 7–8).
