7B5FBE35B14DFFD4E90DFC9D9404FDD5.taxon	etymology	Etymology.

Pronotum. Strongly transverse, lateral margins sinuately converging anteriorly; disk flat with a shallow median depression; anterior and posterior margins concave. Scutellum. Of semicircular shape, wider than long; surface flat without carinae. Hemelytra. Corium about as long as scutellum, clavus distinct; membrane hyaline with distinct veins. Legs. Unarmed. Femora distinctly thickened, tibiae slender, tarsi two-segmented, claws with pulvilli. Abdomen. Lateral margins subparallel and straight, deltg VII truncate posteriorly; pattern of apodemal impressions of deltg II-VII and tergal disk not clearly discernible, supposed to be arranged as 2 (1): 1: 1. Venter. Obscured by impurities; sternites III-VI separated by transverse sutures.	en	HEISS, ERNST (2022): Pachytylaradus cretaceous gen. et sp. nov. from Burmese amber (Heteroptera, Aradidae).

7B5FBE35B14DFFD4E90DFC9D9404FDD5.taxon	discussion	Remarks. The general habitus resembles at first glance a specimen of the subfamily Aradinae or Mezirinae. However Pachytylaradus is distinguished from Aradinae by the structure of head and the presence of pulvilli, from Mezirinae by lack of metathoracic scent glands. This new genus differs from the other extant subfamilies (Aneurinae, Calisiinae, Carventinae, Chinamyersiinae, Isoderminae and Prosympiestinae) (Usinger & Matsuda, 1959) and the Burmese amber fossil Archearadinae Heiss & Grimaldi, 2002, basically by its habitus and the set of body structures listed above but not shared by one of them. Pachytylaradus might be classified as a member of a new subfamily, which should be based on a phylogenetic analysis as a result of a careful comparison and evaluation of all available characters including other Burmese amber taxa. This is a future study, presently not yet feasible.	en	HEISS, ERNST (2022): Pachytylaradus cretaceous gen. et sp. nov. from Burmese amber (Heteroptera, Aradidae).
