Platythyrea janyai

The type series and all material examined of P. janyai were collected from small dead wood on the forest floor in lowland rainforests.

Identification
Phengsi et al. (2018) - Platythyrea janyai and Platythyrea clypeata are very similar in general appearance as they share the following characteristics: body reddish brown; frontal lobe narrow; frontal carinae closely spaced and strongly narrowed posteriorly; mandible triangular, its masticatory margin with a large apical tooth, followed by 9–10 smaller teeth, large and smaller teeth alternating; propodeal spiracle opening elliptical; in dorsal view posterior margin of petiole convex without spines. However, Platythyrea janyai can be easily separated from Platythyrea clypeata by the following characteristics: head relatively shorter (CI 72–74 in Platythyrea janyai; CI 61–69 in Platythyrea clypeata); eye clearly larger (EL 0.20 mm with eleven ommatidia on longest axis in Platythyrea janyai; EL 0.10 mm with five ommatidia on longest axis in Platythyrea clypeata); eye convex (flat in Platythyrea clypeata); dorsum and lateral face of head finely micropunctate without foveae (finely punctate with dense shallow foveae in Platythyrea clypeata); in profile view petiole clearly longer than high and in dorsal view node of petiole anteriorly as broad as posteriorly (slightly longer than high and in dorsal view node of petiole slightly narrower posteriorly in Platythyrea clypeata); ventral outline of petiole weakly convex (feebly concave in Platythyrea clypeata). No overlap is observed in HW / SL between the species. Platythyrea janyai (Malay Peninsula: S Thailand and W. Malaysia) is distinctly allopatric with Platythyrea clypeata (known from from Sri Lanka, Vietnam, Laos, and east Thailand).
