On immature and adult forms of Trichognathus marginipennis Latreille, 1829 (Coleoptera, Carabidae, Galeritini)

Abstract

The pupa of Trichognathus marginipennis Latreille, 1829 is described for the first time and the adult is redescribed. Habitus and important structures of larva, pupa and adult are illustrated. This work improves the knowledge on immatures and adults of Trichognathus marginipennis.

The preimaginal stages of Galerita ruficollis Dejean, 1825 and the position of the tribe Galeritini in the classification of ground beetles (Coleoptera, Carabidae)

“…On the contrary, long outgrowths on abdominal segments II-VI (Fig. 11A, B) have been described in all pupae of Galeritini (Sallé 1846;Schaupp 1882;Costa et al 1988;dos Santos 2012). Based on their topology and chaetotaxy, these outgrowths correspond to larval epipleurites (Fig.…”

“…It seems noteworthy that a gregarious behavior during cooperative hunting of the adults and larvae has been recorded in Trichognathus marginipennis (dos Santos 2012). Moreover, this species shares the same environment and forms of aggregation with species of Tetracha Hope, 1838 (Arndt and Drechsel 1998;dos Santos 2012). Besides Galeritini, multispecies aggregations of different species of Brachinus Weber, 1801 (Wautier 1971;Juliano 1985;Schaller et al 2018), as well as aggregations of some Brachinus species with Anchomenus dorsalis (Pontoppidan, 1763) and/or with Chlaenius chrysocephalus (P. Rossi, 1790) have also been observed (Zaballos 1985;Bonacci et al 2004Bonacci et al , 2011Zetto-Brandmayr et al 2006).…”

“…All previous authors considered the bifurcated protrusion at the anterior margin of the frontale (Figs 7A, 8A-C) as a "nasale" ( van Emden 1942;Thompson 1979;Costa et al 1988;Arndt and Drechsel 1998;Dajoz 2005;Bousquet 2010;dos Santos 2012). Moreover, none of them, except Costa et al (1988), paid attention to the paired teeth lying ventrally at its base (Fig.…”

“…Despite the characteristic, unmistakable, and easily recognizable habitus of the Galeritini larvae, information concerning them is very scant. Third instar larvae of nine species of Galerita (Sallé 1846;Candèze 1861;Hubbard 1875;van Emden 1942;Kawada 1959;Thompson 1979;Kirk 1980;Costa et al 1988;Dajoz 2005;Bousquet 2010) and of Trichognathus marginipennis Latreille, 1829 (Arndt and Drechsel 1998;dos Santos 2012), as well as pupae of three Galerita species (Sallé 1846;Schaupp 1882;Costa et al 1988;Dajoz 2005) and of T. marginipennis (dos Santos 2012) have been described, albeit with a varying degree of detail. The specific features of chaetotaxy in Galeritini larvae have only briefly been mentioned (Arndt and Drechsel 1998;Bousquet 2010).…”
