Creobroter apicalis Saussure, 1869 View in CoL
is documented in Sri Lanka for the first time. The species sampling occurrence (July-October) aligned closely with data reported in the database, GBIF (Global Biodiversity Information Facility: www.gbif.org) indicating a strong coincidence between observed occurrences and documented records.
A taxonomic key was developed to accurately distinguish C. apicalis from C. pictipennis , facilitating precise identification of these two mantid species based on morphological and diagnostic features ( Fig. 3 View FIGURE 3 ) critical for comparative analyses ( Ghate et al. 2000).

General description. Medium to large insects, greenish body, winged. Forewing with yellow band in the middle, bordered by two black semi-circular rings resembling an eye spot, enclosing black dots, typically two; costal and anal areas transparent, base with a yellow spot. Head trapezoidal with prominent lateral lobes; conical eyes with upward projection, black band having white tips, small mid-dorsal spine. Ocelli conspicuous. Antennae slender, filiform. Saddle-shaped pronotum, shorter than forecoxae, well-pronounced supra-coxal dilation, laterally denticulated prozona, spatulated central indistinct carina, pronounced metazonal constriction; forecoxae triangular dorsally, eight obtuse marginal spines, middorsal carina with spines, internal apical lobes convergent; femur longer than coxa with four external, four discoidal and 13 internal spines, of which six are longer, seven are shorter; fore tibia with 16 smaller depressed external spines, 14 longer, closely arranged internal spines and three distal genicular spines; Metatarsus as long as all other tarsal segments combined; Middle and hind femora twice as long as middle tibia; raptorial forelegs; semicircular distal ventral lobe, two genicular spines at the tibia-femur junction. Measurements of various phenotypic features given in Table 2 View TABLE 2 , most female measurements and counts slightly greater than those of male (sexual dimorphism).
Female phenotype (♀: RUH ENTM1). Forewing remigium with a green hue, featuring a central eye-like region comprising brown, yellow, and white shades alongside a yellow proximal area. Cross-venation notably dense, comprising more than four rows of cells across most regions. Proximally, the forewing vannus with a light pink coloration transitioning to a dark brown/black hue distally. Hind wing remigium with a dark pink band with a distinct apex, proximally displaying a pink tone shifting to dark brown towards the distal end. Partial overlapping between the dark pink and dark brown/black areas. Within the dark brown/black region, cross-veins surrounded by clear spaces.
Male Phenotype (♂: RUH ENTM2). Male wings longer and with a less dense arrangement of cross-veins than those of female. Forewing remigium lacking the proximal yellow region observed in females. Forewing vannus with a faint trace of a light pink hue. On the hind wing, a light pink region present proximally, blending with a brownish tone; distal area lacking a distinctive black/brown coloration ( Fig. 2 View FIGURE 2 ).
Mitochondrial COI Barcoding and Phylogenetic Analysis. The average intraspecific genetic divergences, calculated using the Kimura 2-Parameter (K2P) method, ranged from 0.003 (for RUH ENTM1 and RUH ENTM2) to 0.015 (for C. apicalis and RUH ENTM1/M2). Hence, no significant genetic variation was discernible within the sampled individuals, assuming a 0.02 threshold for speciation in C. apicalis . In summary, the genetic variations between species, as indicated by sequence divergences in the mitochondrial COI barcoding gene, were greater than the divergences observed within species ( Table 3 View TABLE 3 ). Moreover, the phylogenetically monophyletic clusters observed in Creobroter spp. underscore the taxonomic validity of identifying C. apicalis ( Fig. 4 View FIGURE 4 ).
