Penthicodes (Penthicodes) farinosus (Weber, 1801)

( Figs 4 , 5E–H , 6D , 7B–D , 9B )

Diagnosis. The species is easy to differentiate from the other Penthicodes species by the vertex wider than long in dorsal view with two patches of white waxy secretion. Only P. (Penthicodes) nicobaricus (Stål, 1869) from An- daman and Nicobar Islands shows waxy patches on the vertex but its vertex is as wide as long in dorsal view ( Constant 2010; Constant & Mohan 2017).

Material examined from photographs. Malaysia (Borneo): 1 specimen ( Fig. 6D ) , Sarawak, Mulu National 96 Kawin Jiaranaisakul & Jérôme Constant

Park, 27.II.2009, on Ailanthus integrifolia Lam. ( Simaroubaceae ), W.K. Fletcher & D.M. Baylis.

Thailand: 1 specimen ( Fig. 7D ), Yala Province, Beto- ng, 31.XII.2020, K. Saechan .

Distribution. Borneo, Indonesia (Java, Sumatra), West Malaysia, Myanmar, Philippines (Distant 1901; Lalle- mand 1963; Seidel & Wessel 2013; Bourgoin 2022) and Thailand (new country record).

Note. The record from Tavoy (currently Dawei, Myan- mar), far north of the Isthmus of Kra, by Distant (1906) is regarded as doubtful and further studies are needed for confirmation.

Biology. Penthicodes (Penthicodes) farinosus has been found only in the southernmost part of Thailand. Alstonia scholaris (L.) R.Br. ( Apocynaceae ) is a host plant of P. (Penthicodes) farinosus in Thailand ( Fig. 7B ), while the species was recorded on Ailanthus integrifolia Lam. in Borneo (W.K. Fletcher & D.M. Baylis pers. com., 2020; Fig. 6D ).
