Vertex almost straight.   Remarks.It is similar to  C. vancum  sp. nov.by having the mandibular subupper tooth very small, the apical margin of median clypeal lobe straight, the eyes and ocelli large, the frontal angle of ocellar triangle almost right. However,  C. pongum  sp. nov.has the median lobe of posterior hypopygeal margin convex with median projection short, the membranous region of basiparamere with apical corner strongly developed, and the dorsal paramere slightly longer than ventral paramere, whereas  C. vancum  sp. nov.has the median lobe of posterior hypopygeal margin angulate with median projection long, the apical corner of membranous region of basiparamere not developed, and the dorsal paramere about as long as ventral paramere. It is also similar to  C. salum  sp. nov.by having the anterior region of pronotal disc rounded, the median region of metanotum short and wide, the dorsal paramere slightly longer than ventral paramere, the volsella base with a long sclerite. However,  C. pongum  sp. nov.has the subupper tooth very small, the apical margin of median clypeal lobe straight, the temple slightly divergent, the inner foveae of metanotal furrow not delimited, the hypopygium with posterior margin slightly trilobate, median lobe convex and margin lateral angulate posteriorly, the dorsal paramere more narrow than ventral paramere, whereas  C. salum  sp. nov.has the mandibular teeth equally sized, the apical margin of median clypeal lobe angularly concave, the temple almost parallel, the inner foveae of metanotal furrow delimited, the hypopygium with posterior margin strongly trilobate, median lobe angulate, and lateral margin slightly convex, the dorsal paramere almost as wide as ventral paramere. 1700783625 2008-10-19 2008-10-26 2008-10-19 Yai Thailand Material 200 12.21315 Khao Sam Roi Yot 1 99.9777 Prachuab Khiri Khan 11 232 1 1 holotype 1700783632 2008-09-25 2008-10-02 2008-09-25 Somboon & Daorueng & Yai Thailand 500 14.499534 Huai Mae Kamint 1 98.88392 Khuean Srinagarindra 11 232 1 1 Kanchanaburi holotype 1700783643 2008-10-19 2008-10-26 2008-10-19 Amnad Thailand 200 12.21315 Checkpoint 1 99.9777 11 232 1 1 Kanchanaburi holotype 1700783635 2008-10-26 2008-11-02 2008-10-26 QSBG Thailand 12.21765 Ban Hua Tan Thaeo 1 99.97307 Checkpoint 11 232 1 1 Kanchanaburi holotype
