Preservation: Holotype and paratypes dry and well preserved, with a few imperfections; additional material in 70% alcohol, with some missing parts, but complete enough to be identified as the new species.

Diagnosis: Gonostylus crest dark brown,strongly curved distally with thick long setae ( Fig. 4View Figure 4), yellowish brown anteriorly. Another diagnose characteristic is the wing non-hyaline with only the middle of r₃ and r₄ cells lighter than the borders ( Fig. 3View Figure3).

Male ( Figs. 1‑4View Figure 1View Figure 2View Figure3View Figure 4): length: body ca. 6.5 mm, wing ca. 7.3 mm. General color dark brown ( Fig. 1aView Figure 1). Head in shades of brown ( Fig. 1bView Figure 1). Eyes holoptic, slightly grayish brown with the borders in blackish brown, ommatidium facets round; ocellar tubercle dark brown, ocellus light brown. Gena brown, lighter than the eyes. Bare and strongly curved clypeus. Antenna uniformly light brown with short thin setae, 1.6 times smaller than head; scape flattened, pedicel two times longer than scape, first flagellomere tapering toward apex, clearly narrow- er than pedicel and approximately as wide as scape. Maxillary palpus light brown, distally angled with thick medium-sized setae. Proboscis yellowish brown. Occiput grayish brown, with long-sized setae.

Thorax dark brown ( Fig. 1aView Figure 1), wider than long. Meron almost two times wider than long, katepisternum almost as wide as high ( Fig. 2View Figure 2). Coxa dark brown,femur,tibia, and tarsus light yellow ( Fig. 1aView Figure 1). Wing membrane brownish along most veins ( Fig. 3View Figure3); pterostigma, approximately six times smaller than the wing length; R₁ and R₂₊₃ running parallel for the most part, only last third of R₂₊₃ converging towards R₁; R₄ barely curved; CuA and CuP joining far from wing margin, CuA+CuP as long as r-m crossvein; discal cell approximately 4.2x longer than wide, bm cell five times longer than wide, br cell six times longer than wide, cua cell six times longer than wide, c cell placed before pterostigma; alula broad. Halter light brown ( Fig. 1aView Figure 1).

Abdomen dark brown ( Fig. 1aView Figure 1). Gonocoxite dark brown with long setae; gonostylus apex dark brown, protruding curved crest with long setae ( Fig. 4View Figure 4), bottom yellowish brown; gonostylus with a distal concavity ( Fig. 4eView Figure 4). Aedeagus long, half the gonocoxite length ( Fig. 4View Figure 4). Ejaculatory apodeme long, nearly as long as aedeagus. Gonocoxal apodeme approximately half of the aedeagus length; parameral apodeme short, do not extending beyond the gonocoxal apodeme; lateral ejaculatory process short. Cercus dark brown with short setae, distancing each other distally ( Fig. 4bView Figure 4).

Female ( Figs. 5‑7View Figure 5View Figure 6View Figure 7): Same as males, except as follows: length: body 7.8 mm, wing 7.3 mm. Eyes dichoptic.

Cercus dark brown, two-segmented with slightly rounded apex in the distal segment ( Fig. 6View Figure 6), posteroventral cercal lobe two times longer than wide ( Fig. 7aView Figure 7). Sternite VIII slightly rounded anteriorly; hypogynial valves with long and thick setae ( Fig. 7aView Figure 7); genital fork with a slightly elongated anterior protrusion and distal short apodemes.Three spermathecae oblong ( Fig. 7bView Figure 7).

Geographic distribution: Serra da Bodoquena, state of Mato Grosso do Sul, Midwest Brazilian region ( Fig. 8View Figure 8).

Etymology: Based on its general dark color, the species is named after the fiction author Franz Kafka, whose literature mostly deals with the darkness and absurdity of human behavior.

Comments: Chrysopilus kafkai  sp. nov. resembles Chysopilus plaumanni Santos & Amorim  in the general aspect of the male terminalia. However, C. kafkai  sp. nov. has a distinctive crest occupying almost half of the gonostylus, while the crest in C. plaumanni  is restricted to the distal region of the gonostylus ( Fig. 9View Figure 9).

Our molecular characterization of 28S rRNA of Chrysopilus kafkai  sp. nov. expands the geographical representation of molecular data for the genus, now with sequences from species distributed in three biogeographical regions (Nearctic, Neotropical, and Australian).
