Treatment

Key to the seven new species of reticulatus View in CoL 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 View in CoL 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 View in CoL 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 View in CoL 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 View in CoL

- 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 View in CoL sp. nov.

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