2B568781A6714C5DE6E4FD21FDA93827.taxon	etymology	Etymology Named for its unique cuticular colour. Greek word hetero for different, chros for pigmentation.	en	Wang, Tianle, Yu, Daoyuan, Zhang, Feng (2013): Two new species of Pogonognathellus (Collembola: Tomoceridae) from China, with a discussion of East Asian species.

2B568781A6714C5DE6E4FD21FDA93827.taxon	discussion	Remarks Pogonognathellus heterochros sp. nov. is similar to P. flavescens in details, such as unguis, dental spines and mucro, but it lacks the long beard-like appendix at the base of maxillary lamella 5, which is a significant character in P. flavescens (Yosii 1967; Fjellberg; 2007; Felderhoff et al. 2010). This new species can be easily recognized by the unique body colour in alcohol.	en	Wang, Tianle, Yu, Daoyuan, Zhang, Feng (2013): Two new species of Pogonognathellus (Collembola: Tomoceridae) from China, with a discussion of East Asian species.

2B568781A6744C51E576FDDDFCBC383F.taxon	discussion	Remarks Pogononathellus mai sp. nov. is most similar to Japanese species P. beckeri in dental spines and stout mucronal shape, but the absence of distinct beard-like appendix, the different colour pattern, one seta on corpus of tenaculum and four, four, four ungual teeth indicate that they are different. It is also similar to P. heterochros sp. nov., but is significantly different from it in its smaller body size, relatively shorter antennae, shapes of unguis and mucro, and distinct colour pattern.	en	Wang, Tianle, Yu, Daoyuan, Zhang, Feng (2013): Two new species of Pogonognathellus (Collembola: Tomoceridae) from China, with a discussion of East Asian species.
