Praepodothrips causiapeltus Reyes

( Figs 178–184 )

Praepodothrips causiapeltus Reyes, 1994: 469 .

This species was described from Palawan, the Philippines, based on one female and five males collected from Bambusa sp. leaf sheath. Although the type specimens have been unavailable for this study, a series of specimens from Southeast Asia listed below are indistinguishable from the original description. Thus, these specimens are identified as P. causiapeltus in this study, and it is recorded here from Peninsular Malaysia, Thailand and Vietnam for the first time. Contrary to the original description, according to Dang et al. (2014), the holotype female and one paratype male of causiapeltus has (2+2 +1) sense cones on antennal segment IV and two pairs of expanded posteromarginal setae on tergite IX (see Fig. 140 in Dang et al.). Specimens from Southeast Asia also coincide with these features. It is probably very closely related to P. priesneri from India, but it may can be distinguished by the well-developed prothoracic midlateral setae and the expanded S1 and S2 setae on tergite IX. The male of this species shows extreme allometric growth. In addition, the pelta of this species is variable in shape, hat-shaped to trapezoid ( Figs 182 & 183 ). Moreover, the length and shape of the prothoracic anteromarginal setae are also variable, short and pointed to moderately long and weakly dilated.
