Cyphonia sakakibarai Mckamey 2017, n. sp.

Cyphonia sakakibarai, n. sp.

(Figs. 3–7)

Diagnosis. Body orange except with some black markings; pronotum with suprahumeral spines straight and distal trifurcate process non-bulbous.

Description of male. Dimensions (mm): pronotal length 4.3, width across suprahumeral spines 2.3; width across lateral braches apices of distal trifurcate process 2.4. Pronotal surface smooth, covered with long black setae, overall orange, darker anteriorly, except black posteriorly on suprahumeral spines, on apices of median process, and on base, lateral spines, and at mid length of central spines of distal trifurcate process. Abdominal pygofer black. Pronotum with suprahumeral spines located anteriorly in lateral view, almost straight in dorsal view; distal trifurcate process elevated, lateral spines narrow and attenuate. Forewing veins black, cells hyaline. Genitalia. Aedeagus symmetrical, shaft laterally compressed, with single apical gonopore, apex with 1 pair of apical, flattened processes, serrate along their outer margins, extending ventrally and slightly laterally, to about 2/3 length of shaft, twisted 180 degrees distally at mid length (Fig. 7).

Female. Unknown.

Material examined. Holotype male, “ BRAZIL: Rondonia [sic]. 62 | km SW Ariquemas, nr | Fzda. Rancho Grande | 30-III-10-IV-1992 | J. E. Eger, coll.”, “collected at | mercury vapor & | black lights,” and “ HOLOTYPE | Cyphonia | sakakibarai | S.H. McKamey ” (DZUP).

Distribution. Brazil: Rondônia Sate.

Etymology. This species is named in honor of Dr. A. M. Sakakibara for his significant contributions to our knowledge of Cyphonia.

Discussion. The aedeagus of the new species is unlike any previously described species, most of which are serrate or dentate on the shaft margins distally or have only very short apical processes. Other species of Cyphonia with narrow distal trifurcate processes include: C. longistyla Sakakibara (Fig. 1); and C. trifida (Fabricius) and C. flavomaculata Sakakibara, which are both similar to C. longistyla but with shorter spines.
