Troilus luridus (Fabricius, 1775) ( Hemiptera , Pentatomidae ,

Asopinae ) (Fig. 1) is a woodland shieldbug that lives on a variety of tree species, both deciduous and conifers

( PÉRICART, 2010; LUPOLI & DUSOULIER, 2015). As occurs with the other asopines, T. luridus is a predatory species that feeds, both as a nymph and in adulthood, of small caterpillars and pupae of Lepidoptera, but also of soft-bodied larvae and adults of other insects ( PÉRICART, 2010). The species has an

Euro-Siberian distribution extending from the Iberian

Peninsula to Russia, China, Korea, India and Myanmar, reaching

England and Scandinavia to the north ( RIDER, 2006;

PÉRICART, 2010).

In Portugal, T. luridus was only recorded from two sites – Mata de Leiria and S. Pedro de Moel ( SEABRA, 1928,

1929, 1939 a, 1939b) – located not only in the same district

(Leiria) but also in what can be effectively considered a single area, since the coastal village of S. Pedro de Moel is Fig. 1.- Specimen of Troilus luridus in Parque surrounded by Mata de Leiria, a large pine tree forest, on its das Ribeiras do Rio Uíma (Santa Maria da Feira, Portugal).

The new records presented raise from one to three the number of Portuguese districts where the presence of Troilus luridus is confirmed, therefore significantly increasing the known distribution of the species in Portugal, as shown in Map 1. Map 1.- Portuguese distribution of Troilus luridus (Fabricius, 1775), with the Furthermore, these records are the first in the country in over

previously known Portuguese district (in 90 years, since the only study with primary records is that of grey), the new Portuguese districts (in SEABRA (1928), the remainder of the references being citations green), and the MGRS 10× 10 km squares of of that earliest one. the collecting/observation sites in Portugal
