Treatment

Key to the seven new species of reticulatus group with similar wing pattern to C. reticulatus Lutz

(primarily for females)

1. Third palpal segment with multiple shallow, irregular sensory pits on ventral, dorsal and lateral sides of segment ( Fig. 5 View FIGURE 5 F); proboscis moderately long, P/H ratio 0.80–0.94; unequal sized spermathecae ( Fig. 5 View FIGURE 5 E)................. C. irregularis sp. nov.

- Third palpal segment with one or two sensory pits; proboscis and spermathecae various.............................. 2

2. Third palpal segment with two well defined sensory pits on distal 2 / 3 of segment, the basal one on ventral side and the distal one on lateral side ( Fig. 3 View FIGURE 3 D); mandible with 21 teeth; [male tergite 9 with very short and blunt apicolateral processes, with distinctly posteromedial notch; parameres ending in a ventral lobe; basal arch of aedeagus extending to 2 / 3 of total length ( Fig. 3 View FIGURE 3 G)]............................................................................... C. diplus sp. nov.

- Third palpal segment with one sensory pit on ventral side; mandible teeth various.................................. 3

3. Sensory pit deep, round and opening in a small pore ( Fig. 6 View FIGURE 6 E); proboscis moderately long, P/H ratio 0.86–0.95; mandible with 16 teeth............................................................................. C. profundus sp. nov.

- Sensory pit shallow; proboscis long; P/H ratio 1.0– 1.28; mandible with 19–25 teeth................................ 4

4. Large species, wing length 1.30 mm; eyes separated by ½ ommatidium ( Fig. 1 View FIGURE 1 C); [parameres sinuous without ventral lobe ( Fig. 1 View FIGURE 1 K); basal arch of aedeagus extending to ½ of total length ( Fig. 1 View FIGURE 1 J)].......................... C. reticulatus Lutz

- Smaller species, wing length 0.80–1.16; eyes separated by <½ ommatidium....................................... 5

5. Third palpal segment rhomboidal, greatly swollen at middle length; sensory pit irregular occupying the distal ½ of segment ( Fig. 8 View FIGURE 8 F)............................................................................. C. rhombus sp. nov.

- Third palpal segment not rhomboidal, slightly swollen; sensory pit regular, round occupying the middle portion of segment..................................................................................................... 6

6. Wing length 1.03–1.16; a single pale spot over r-m crossvein ( Fig. 4 View FIGURE 4 A)......................... C. fluminensis sp. nov.

- Wing length 0.80–0.95; pale spot over r-m cross vein subdivided................................................ 7

7. Sensory pit small and round, with no well-defined contours on distal ½ ( Fig. 7 View FIGURE 7 E); P.R. 2.0– 2.7; mandible with 19 teeth; two slightly unequal ovoid spermathecae ( Fig. 7 View FIGURE 7 F)....................................... C. pseudoreticulatus sp. nov.

- Sensory pit large and oval, with defined contours ( Fig. 2 View FIGURE 2 G); P.R. 2.6–3.2; mandible with 24 teeth; two unequal ovoid spermathecae ( Fig. 2 View FIGURE 2 E)....................................................................... C. amazonicus sp. nov.
