The predatory stink bugs are well known by their behavior, but the knowledge of the immature morphology and their natural history are scarce. Studies on predatory stink bugs are important to better understand their evolution and their use as biological controllers. Here, we describe the morphology of egg and the five nymphal instars of Oplomus catena (Drury, 1782), using optical and scanning electron microscopy. In general, O. catena immatures are very distinctive from other Asopinae species already studied. The egg is black, with short aero-micropylar processes and similar to those described for Stiretrus species. The nymphs can be diagnosed by the abdominal plates very large and bright blue. The color polymorphism of adults is fully illustrated, and four color patterns are proposed. The natural history of the species is described based on field and laboratory observations. The known prey of the species is reviewed and new preys are reported. The morphological and biological traits here described are discussed in order to better understand the biological role of predatory stink bugs.

“…The presence of three pairs of larval DAGs is considered a plesiomorphy within Pentatomomorpha, occurring in Aradoidea, Pentatomoidea, Pyrrhocoroidea, Lygaeoidea (Artheneidae, Colobathristidae, Heterogastridae, Lygaeidae: Ischnorrhynchinae, Malcidae: Malcinae, Ninidae, most Rhyparochromidae); various reductions in number of DAGs then should be regarded as derived character states (ŠTYS 1964, COBBEN 1978, SCHUH & SLATER 1995, HENRY 1997a, DAVIDOVÁ-VILÍMOVÁ & PODOUBSKÝ 1999, DAVIDOVÁ-VILÍMOVÁ 2006, VILÍMOVÁ & KUTALOVÁ 2012. Reduction of the anterior pair between terga III and IV, with only the middle (IV/V) and the posterior (V/VI) pair of DAGs developed, occurs besides Hyocephalidae also in the remaining Coreoidea (Alydidae, Coreidae, Rhopalidae, and Stenocephalidae), Idiostoloidea and many families of Lygaeoidea (Blissidae; Cryptorhamphidae; Geocoridae; Lygaeidae: Lygaeinae, Orsillinae; Malcidae: Chauliopinae; Oxycarenidae; Pachygronthidae) (e.g.…”

Abstract Hyocephalidae (Hemiptera: Heteroptera: Pentatomomorpha) is a small family of true bugs containing two genera and three species endemic to Australia. For the first time, we examine here selected structures of their external morphology using scanning electron microscopy – the external structures associated with the metathoracic and dorsoabdominal scent glands, the strainer organ on the sternite III, as well as the trichobothrial pattern and ultrastructure. The following character states are confirmed (i, ii, iii) or newly recognised (iv, v) as autapomorphies of Hyocephalidae: i) apically projected scimitar-shaped peritreme of the metathoracic scent glands; ii) presence of a strainer organ on sternite III in both sexes; iii) trichobothria on sternite V placed immediately ventrad of spiracle, iv) trichobothria on each of abdominal segments III–VII all grouped together within a common trichome, and v) presence of crocus-like structures within the trichome. Of particular interest is the presence of a shallow open bothrium (type B) surrounded by a trichome in Hyocephalidae, a probably derived character state shared with Pyrrhocoroidea and most Lygaeoidea, while Stenocephalidae (previously considered to be closely related to Hyocephalidae and used here for comparison) and the remaining Coreoidea possess a recessed bothrium of type A2, lacking the trichome. The morphology of trichobothria in Hyocephalidae may thus suggest either their closer relationship to Lygaeoidea + Pyrrhocoroidea than to Coreoidea, or a parallel evolution of the open bothrium with trichome in Eutrichophora. We highlight the importance of Hyocephalidae for a better understanding of the phylogeny of Eutrichophora and the urgent need to obtain phylogenomic data for future research. A taxonomic catalogue of Hyocephalidae is supplemented. The neotype designation for Hyocephalus aprugnus Bergroth, 1906 made by ŠTYS (1964) and supported by GRANT & ŠTYS (1970) is found invalid.
