(b) RBS1, RBS2, and PES are spread unevenly …Finger-like sensillum (FRS) (Figure 2(b)). The base and tip of this type of sensillum are of the same width, but the shaft is slightly wider in the middle. This type of sensilla has been observed only in the Gelastocorinae (Gelastocoris oculatus Figure 16(f)).Freniale-like sensillum (HLS) (Figure 2(c)). This sensillum is designed as a long, thin hair with a tapered tip. It has been observed in the Gelastocorinae (Gelastocoris oculatus, Figures 16(b), 16(f), and 16(g)).Chaetic sensillum with a bisected tip (CHB) (Figure 2(d)).

The tip of the seta is divided into two short branches. This type of sensillum has been found only in the Nerthra nepaeformis (Figure 17(e)) (Gelastocoridae: Nerthrinae).Star-like sensillum (STS) (Figure 2(e)). It is a short cone divided into four or five narrow lobes. The base of the sensillum is sunken in a socket, and it is situated shallowly in a cavity. The lobes are prominent above the cuticular surface. This type of sensillum has been specific to the Aphelocheiridae (Aphelocheirus aestivalis, Figures 18(c), 18(d), and 18(e) and A. variegatus).Multilobed sensillum (MPS) (Figure 2(f)). This type of sensillum consists of a few narrow lobes, arising from a common stem. The base of the sensillum is sunken in a socket and the lobes evidently protrude above the cuticular surface.

This type of sensillum has been found in the Limnocorinae (Limnocoris lutzi, Figures 21(a) and 21(c)), Cryphocricinae (Cryphocricos hungerfordi, Figures 22(a), 22(b), 22(c), and 22(d); Ambrysus occidentalis, Figures 23(a), 23(c) and 23(e)) and the Naucorinae (Naucoris maculatus, Figure 24(a); Namtokocoris siamensis,Figure 24(d); Neomacrocoris handlirschi,Figure 24(g)) as well as in Ilyocoris cimicoides and Pelocoris femoratus, (Table 2).Figure 21Types and sizes of the sensilla of the Naucoridae: Limnocorinae (Limnocoris lutzi).
