Scutelleridae

description: Scutelleridae are the second most speciose family within Pentatomoidea, with about 450 described species distributed in roughly 80 genera worldwide. They include some of the most colorful true bugs. Also called shield bugs, scutellerids are characterized by the enlarged scutellum, which covers most of the hemelytra and abdominal segments. Their size ranges from 5 to 20 mm (Javahery <i>et al.</i>, 2000). Several species in different infrafamilial groups are strikingly polymorphic. As a consequence, the number of synonyms for these taxa is high. Polymorphic color patterns for species recorded from Argentina were described and illustrated for <i>Pachycoris torridus</i> (Monte, 1937; Sánchez-Soto <i>et al.,</i> 2004; Santos <i>et al</i>., 2005), <i>Agonosoma flavolineata</i> (Paleari, 1992a, 1994), <i>Augocoris illustris</i> (Barber &amp; Bruner, 1932), and occur in other genera as well. Polymorphism is usually sexrelated, as in <i>P. torridus</i>, with 17 morphs described, adult males frequently monochromatic and adult females polycromatic (Santos <i>et al.</i>, 2005). Also in some other Neotropical genera, there is a clear sexual dimorphism, males with a variegated color pattern and females with large spots. Surprisingly, this large group has been little studied, especially in the Neotropical region. Catalogs that treat world scutellerids are Lethierry &amp; Severin (1893) and Kirkaldy (1909). The last published revision and key for world genera is Schouteden (1904). McDonald &amp; Cassis (1984) and Cassis &amp; Vanags (2006) revised the Australian fauna. Palearctic scutellerids have been studied by Fischer (2001) and more recently by Carapezza (2009). Afew Neotropical genera have been revised (Eger, 1987, 1990; Paleari, 1992a). Eger &amp; Lattin (1995) clarified generic placement of some species and proposed new synonymies. The status of Scutelleridae has changed during its taxonomical history, being included by earlier authors as a tribe or subfamily within Pentatomidae (e.g., Stål, 1872; Schouteden, 1904; Kirkaldy, 1909; Leston, 1952). The most recent authors, however, agree with the familial ranking of the group (McDonald, 1966; Gross, 1975; McDonald &amp; Cassis, 1984; Cassis &amp; Vanags, 2006; Grazia <i>et al.</i>, 2008). Their monophyly is widely accepted, although most cladistic studies have included few representatives of this family (e.g., Gapud, 1991; Fischer, 2001; Grazia <i>et al.</i>, 2008) and additional studies are needed. The relationship of Scutelleridae to other pentatomoid families differs among authors, and their phylogenetic position varies from basal to more apomorphic. In a study employing molecular and morphological characters, the position of Scutelleridae within Pentatomoidea was ambiguous, its position dependent on the character set used in the analysis (Grazia <i>et al.</i>, 2008). However, they were usually positioned basally relative to Pentatomidae. The infrafamilial classification has been controversial. Cassis &amp; Vanags (2006) listed five subfamilies: Elvisurinae, Odontotarsinae, Pachycorinae, Scutellerinae, and Tectocorinae. Carapezza (2009) proposed a new subfamily, Hoteinae, to include the Old World genera <i>Hotea</i> and <i>Deroplax</i>. The definition of Pachycorinae was questioned by the author, as they share several characters with Odontotarsinae. Hoteinae were accepted in Rider’s classification (Rider, 2010), but he mantained the status of Pachycorinae, as well as Elvisurinae, Eurygastrinae, Odontoscelinae, Odontotarsinae, Scutellerinae, and Tectocorinae. In the Neotropics, Scutelleridae are represented by 25 genera of Pachycorinae and one genus of Scutellerinae, <i>Augocoris.</i> Argentinean scutellerids were studied by Stål (1870, 1872), Berg (1878, 1879, 1891, 1892a, b), Montandon (1894), Schouteden (1904), Pennington (1923), Bosq (1937, 1940), Pirán (1948, 1963, 1970), Eger (1990), and Paleari (1992a). Diagnosis Small to medium-sized, ovoid to elongate-ovoid in shape; most of Neotropical species are dull coloured, with a few exceptions (<i>Pachycoris</i> spp., <i>Agonosoma</i> spp., and <i>Augocoris</i> spp.). Antennae 3- (Scutellerinae) or 5-segmented (Pachycorinae). Scutellum enlarged and almost entirely covering hemelytra and abdomen. Femora and tibiae unarmed. Hemelytra with frenum reduced or absent, corium and clavus membranous distally. Propleura with laminate carinae (Schuh &amp; Slater, 1995). Ostiolar peritreme of metathoracic glands absent to well developed, variable in shape, length and distance from metacoxae. External genitalia visible or concealed by seventh sternite. Aedeagus usually with three pairs of conjunctival processes. Female gonocoxites 9 (= second valvifers) fused medially (Gapud, 1991), with visible fusion line (Grazia <i>et al.</i>, 2008). Tricobothria paired. All Pachycorinae with stridulatory areas on lateral thirds of abdominal venter (Schuh &amp; Slater, 1995). Biogeography Themajorityof studiedspecimenswere collectedinthe provinces of Buenos Aires, Corrientes, Córdoba, Salta, Tucumán, and Misiones. Thus, most of the records are from the, Pampa, Chaco, and Parana biogeographic provinces, all included in the Chacoan subregion (Morrone, 2006). More collection efforts are needed in the Monte, Neotropical arid zone, and at the limit with the Andean-Patagonian region. Also, extensive collections in Patagonian, Prepuneña and Puneña biogeographic provinces could reveal altitudinal and latitudinal limits of distribution. Biogeographic works using methods of historical biogeography have not included scutellerids, probably because information about their distribution and phylogeny is still scarce. Scutelleridae in Argentinean collections The most representative collections for Argentinean scutellerids are the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” (MACN), Instituto Fundación Miguel Lillo (IFML), and Museo de La Plata (MLP). Since there are no Argentinian researchers currently working on scutellerids, most of the material is represented by specimens studied by former workers on Heteroptera, such as Berg and Pirán. MLP contains the types of Berg’s species, including the holotype of <i>Coptochilus lentiginosus</i>; eight syntypes of <i>Tetyra poecila</i> and one syntype of <i>Diolcus pusillus</i> (= <i>Misippus spinolae</i>) (Coscarón &amp; Froeschner, 2000). Some species, although not yet recorded for Argentina, are deposited in these collections, such as <i>Lobothyreus lobatus</i>, collected in Misiones province. The identification of undetermined specimens deposited in the Argentinean collections would offer a much clearer picture of the diversity in the country.

Economic importance In a broad sense, scutellerids are generalist phytophagous pentatomoids. Excepting for the Holarctic <i>Eurygaster</i>, that feed mainly on grasses such as wheat (Javahery <i>et al.</i>, 2000), most scutellerids are not crop pests (Javahery <i>et al</i>., 2000). In the Neotropics, the only species reported as economically important is the polyphagous <i>P. torridus</i> (Sanchez-Soto <i>et al.</i>, 2004), especially on orchards (Fig. 1, Table I). Biological aspects All species are considered generalist phytophages (Javahery <i>et al.</i>, 2000), but the host plants are known for only a few species (Table I). Euphorbiaceae, Poaceae, Myrtaceae, and Malvaceae are among the most frequently cited families of host plants (Rider, 2010). <i>Pachycoris torridus</i>, by far the most studied scutellerid in the Neotropics, feeds mainly on Euphorbiaceae, although being reported on several phylogenetically unrelated host plant species in Brazil (Santos <i>et al.</i>, 2005). Feeding on euphorbs is possibly related to acquisition of toxic compounds used against predators by this aposematic species (Santos <i>et al.</i>, 2005). Santos <i>et al.</i> (2005) cite <i>Cnidoscolus pubescens</i> (Euphorbiaceae) as the native host plant for <i>P. torridus</i>. Similarly, Cervantes-Peredo (2002), in Central America, reported the occurrence of <i>Pachycoris klugii</i> on <i>Cnidoscolus multilobus</i>. In southern Brazil, we have observed adults and egg masses of <i>Chelycoris haglundi</i> on <i>Croton</i> sp. (Euphorbiaceae), and adults of <i>Ascanius</i> sp. on <i>Rubus erythrocladus</i> (Rosaceae). <i>Croton</i> sp. was also observed as host plant for <i>C. haglundi</i>, <i>Chelycoris lethierryi</i>, <i>Orsilochidesleucoptera,</i> and <i>A. flavolineata</i> in the state of Mato Grosso do Sul, central Brazil. There are few studies of the biology or description of immature stages for Neotropical taxa (Monte, 1937; Paleari, 1992a, b; Peredo, 2002; Santos <i>et al.</i>, 2005). As in other pentatomoids, nymphal development includes five instars. In <i>A. flavolineata</i>, egg masses have a mean number of 14 eggs, laid in two rows. In the laboratory, the total development from egg to adult took about 40 days (Paleari, 1992b). Nymphs of this species are gregarious until third instar, in both field and laboratory conditions (Paleari, 1992b). Santos <i>et al</i>. (2005) observed two egg masses laid by <i>P. torridus</i>, with 75 and 92 eggs, respectively. In the second egg mass, 35.8% of the eggs were parasitized by an undentified Trichogrammatidae (Hymenoptera: Chalcidoidea). These data are very similar to those found by Cervantes-Peredo (2002) for <i>P. klugii</i> (average of 81.4 eggs per mass, 38% of eggs parasitized by a scelionid wasp). Costa Lima (1928) described <i>Pseudotelenomus pachycoris</i> from <i>P. torridus</i> in Brasil. The tachinid flies <i>Trichopoda pennipes</i> and <i>Trichopoda pallipes</i> were reported parasitizing <i>P. torridus</i> in Brasil (Guimarães, 1977). Maternal care was recorded for <i>P. torridus</i> by Hussey (1934) and Santos <i>et al.</i> (2005). Adult females were observed guarding first-instar nymphs. This behavior had also been described for <i>P. klugii</i> on eggs and first-instar nymphs (Cervantes- Peredo, 2002). Inventories carried out in southern Brazil have showed specimens of <i>P. torridus</i> and lessfrequently <i>C. haglundi</i> and <i>Tetyra</i> sp. inside terrestrial bromeliads during the cold season, apparently in diapause (unpublished data, Fig. 2). This habit was also reported for <i>P. klugii</i> (Cervantes-Peredo, 2002). Conclusions The scarcity of information on Argentinean taxa reflects the lack of taxonomical and biological works on Neotropical scutellerids, compared with other biogeographical regions and other pentatomoids. There is an urgent need for basic research, including taxonomic revisions, phylogenetical analyses, inventories, community studies, and acquisition of data on host plants and predator-prey relations. In the Pachycorinae, many genera need revision, such as <i>Symphylus</i> and <i>Tetyra</i> (Figs. 3, 4), a large complex of widely distributed species in the Neotropics.
