Key to the Teuchothrips species from New Caledonia

1. Maxillary stylets widely separated, about 50% of head width apart, retracted into head no more than one third of distance to posterior margin of eyes................................................................................ 2

- Maxillary stylets close together, no more than 25% of head width apart and sometimes crossing over each other, retracted to posterior margin of eyes................................................................................ 3

2. Fore tibia of both sexes with small tubercle at inner apex; postocular and pronotal major setae pointed; antennal segment III yellow, IV–V bicolored; fore wing with 13–16 duplicated cilia.......................................... cleistanthi

- Fore tibia of both sexes without apical tubercle; postocular and pronotal major setae weakly capitate; antennal segments III–V yellow; fore wing with 10–12 duplicated cilia.......................................................... kraussi

3. Occipital ridge of head simple and transverse ( Fig. 4 ); head extensively reticulate; pronotal anteromarginal setae small, 0.25 as long as antennal segment III, 0.16 as long as epimeral setae............................................... ornatus

-. Occipital ridge of head with curved sculptured area medially ( Fig. 3 ); head with transverse lines, reticulate posterolaterally; pronotal anteromarginal setae well developed, 0.5 as long as antennal segment III, 0.5 as long as epimeral setae..................................................................................................... noumeaensis
