Sampling method efficiency. -

Light trapping was the most efficient sampling method, with almost 1000 specimens captured, while day collecting only resulted in the collection of 250 specimens (Fig. 5 View Figure 5 ). As for orthopterans, we observed that many mantises were attracted more efficiently by diffuse light (camp lamp in tents, classic neon, low energy consumption lamps) than by the 250W UV light traditionally used in light traps for moths and beetles. As expected, the proportion of females and nymphs was higher during the day than with light traps, and interestingly the number of species collected with both methods was not significantly different (Fig. 6 View Figure 6 ). Sampling completeness, represented by the % of estimated richness that has been observed in the samples, was higher for light trapping (ca. 92%) than for day collecting (ca. 74%), suggesting that additional sampling effort with this last method would be necessary to reach an accurate estimation of the mantid community diversity. Figure 7 View Figure 7 shows the number of species caught specifically for each method.

DNA barcoding versus traditional taxonomy. -A total of 94 sequences of more than 200°bp were obtained from 119 specimens analysed. Except in a few cases, the delimitation of taxonomic units on the basis of genetic information contained in the barcodes was congruent with the species limits acknowledged by traditional taxonomy (Fig. 8 View Figure 8 ).

Diversity patterns of praying mantids. -

The rarefaction curve obtained for the whole data set (Fig. 9 View Figure 9 ) indicates that the sampling effort was sufficient to provide a representative picture of Mantodea diversity at a regional scale. As exemplified by this figure, doubling the number of collected specimens would only result in the addition to the checklist of a small number of new species. Figure 10 View Figure 10 shows diversity patterns in the three major geographical units of the study region, i.e. Dzanga-Ndoki National Park, Dzanga-Sangha Special Reserve and the rest of Sangha-Mbaere Region.

The higher observed and estimated species richness was found in the Dzanga-Ndoki NP, where the number of species was close to the number observed at the regional scale, meaning that most of the regional species pool was present in this area (Fig. 10 View Figure 10 ).

Vegetation structure.-

Figures 11 View Figure 11 to 13 present the number of individuals and the diversity of mantids collected along a height gradient from the herbaceous layer to the top canopy. Most of the mantids captured were males because the main method of surveying was through the use of light traps. However, both in top canopy and in the tree stratum, a higher proportion of females were collected by active search and light trap, maybe because UV light was placed nearer to the microhabitats where females resided. The number of specimens found in the soil and herbaceous strata was lower than in other strata because the study area is largely situated in a forest context (Fig. 11 View Figure 11 ). Both observed and estimated species richness were the highest between the shrub layer and the top canopy). However, a significant number of species was found in the herbaceous surroundings and edges of the swamps and lakes (Fig. 12 View Figure 12 ). Each stratum of the vegetation harbors species in a specific way but the species also overlap somewhat in different vegetation types (Fig. 13 View Figure 13 ).
