Description. Wing length. 1.8–2.0 mm (♂), 2.0 mm (♀). Length of ultimate section of vein M 4 divided by penultimate section: 1.1–1.2. Eye height divided by gena height: 12–12.5. Ocellar triangle long, almost reaching to posterior ori. Fronto-orbital plate and parafacial not prominent. Lunule higher than wide, narrower near to suture and reaching anterior ori. First flagellomere short, oval, kidney-shaped and with small hairs. Arista long, short pubescent. Gena narrow and rounded, slightly projecting posteriorly ( Fig. 8A–D View Figure 8 ).

Chaetotaxy. Two to three incurved ori, shorter than ors; two to three reclinate ors equally developed. Ocellar and postocellar setae subequal to ors. One row of long and reclinate orbital setulae. Eye pilose in males. Three setae apically on each palpus. Presutural dorsocentral absent, three postsutural dorsocentral setae decreasing in length. Four to five rows of acrostichal setulae. Prescutellar acrostichal setae absent. Lateral scutellar setae reduced, about half of the length of the apical setae. Mid tibia with one short and fine lateromedial seta.

Coloration. Body mostly brown. Fronto-orbital plate and ocellar triangle yellowish brown, slightly shining. Frons brown, with pruinosity. Lunule and face yellowish brown with pruinosity. Scape and pedicel yellowish brown. First flagellomere yellowish brown, darker apically. Clypeus slightly shining brown. Palpus brown. Labellum yellow. Scutum and scutellum slightly shining. Pleurae brown, with a yellow stripe on superior and posterior margins of anepisternum. Wing hyaline, yellow at base. Calypter greyish yellow, margin and hairs brown. Halter yellow. Legs brown, with apex of fore femur and base of fore tibiae yellowish, tarsi yellowish on all legs. Abdomen slightly shining.

Genitalia. Epandrium with well-developed and round- ed supra-anal process, without spines on inner margin. Cerci very short and narrow, setulose, with a distinct long apical seta. Surstylus directed inwards with some setae ( Fig. 9A, B View Figure 9 ). Subepandrial sclerite slightly curved apically. Hypandrium U-shaped. Basiphallus long and tubular, sclerotized laterally. Hypophallus long and narrow, membranous dorsally, with a long and curved clear extension basally. Paraphallus absent. Mesophallus narrow. Distiphallus divided in two long, narrow and slightly S-shaped tubules that is 2.5 times longer than mesophallus, widening to little broad apical cup; slightly recurved apically ( Fig. 9C, D View Figure 9 ). Ejaculatory apodeme small, with blade twice larger than stem; sperm pump round and clear, with a rounded sclerotized process laterally ( Fig. 9E View Figure 9 ).

Etymology. The epithet refers to the type locality of holotype and paratypes.

Host. Unknown.

Distribution. Brazil.

Remarks. This species is very similar to Cerodontha (P.) bambusae Martinez, 1992 , specially of the phallus shape. However, differs in the following characters: longer wing length, without presutural and three postsutural dorsocentrals, a shorter mesophallus with a rounded base, and a longer hypophallus. In contrast, C. (P.) bambusae has a shorter wing length of 1.55 mm, 2+1 dorsocentrals, a longer mesophallus, rectilinear at the base, and a shorter hypophallus.
