Review of Coeliaria (Coleoptera: Coccinellidae: Chnoodini)

ABSTRACT

Coeliaria Mulsant, 1850 is revised based on the external morphology and genitalia of the adults and is distinguished from the other Chnoodini by the following characters: dorsal surface pubescent; antenna 11-segmented; hypomera with rounded fovea; tibia flat and angulated; abdominal postcoxal line incomplete, recurved and with oblique line. A new species, Coeliaria castanea sp. nov., from Brazil, and two new combinations, are proposed: Coeliaria bernardinensis comb. nov. and C. luteicornis comb. nov., expanding the distribution of the genus to Bolivia and Paraguay.

KEY WORDS:

INTRODUCTION

Coccinellidae Latreille, 1807 is an ecologically and morphologically diverse group of predators that are often used in biological control programs of insect pests (Hodek and Honěk 1996).

Since the establishment of Coccinellidae as a family, several authors have proposed classification systems for it. Beginning in the second half of the nineteen-century, Mulsant (1846, 1850) proposed a generic classification based on the pubescence patterns. He was followed Crotch (1874) and Chapuis (1876), who divided the family into “Aphidiphages” and “Phytophages”. Casey (1899) recognized 16 tribes, and other authors worked on an improved classification system for the family (Weise 1895, Sicard 1907, 1909). Korschefsky (1931, 1932), in his catalog, recognized three subfamilies and twenty tribes in Coccinellidae, whereas Bouchard et al. (2011) considered only two: Microweiseinae and Coccinellinae. In addition Bouchard et al. (2011) revalidated the name Chnoodini, which was accepted and followed by Seago et al. (2011), González (2013) and Krüger et al. (2016). Nedved and Kovář (2012), however, continued using the name Exoplectrini in their chapter on the phylogeny and classification of Coccinellidae, where they listed 20 genera for the tribe. Although the name Exoplectrini was used by Nedved and Kovář (2012) after the work of Bouchard et al. (2011) to name the tribe, Chnoodini is the correct name for the group, since it was first used by Mulsant (1850) as “Chnoodiens” (Principle of priority) and later Latinized and used by Sicard (1909). Currently, in the Neotropical Region, Chnoodini includes ChnoodesChevrolat, 1849, Coeliaria Mulsant, 1850, Dapolia Mulsant, 1850, Dioria Mulsant, 1850, Exoplectra Chevrolat, 1844, Gordonita González, 2013, Incurvus González, 2013, Neorhizobius Crotch, 1874, Sidonis Mulsant, 1850 and Siola Mulsant, 1850.

Mulsant (1850) described Coeliaria for Exoplectra erythrogaster Mulsant, 1850 based on the presence of “a deep fovea in the hypomera”.

Crotch (1874) briefly redescribed Coeliaria and indicated the presence of thoracic foveae and epipleura subfoveolate in C. erythrogaster. Chapuis (1876) treated Coeliaria as a subgenus of Exoplectra, indicating that the thoracic fovea of C. erythrogaster differs from the condition found in the other species of Exoplectra, which have a flat epipleura. Gemminger and Harold (1876), Korschefsky (1932) and Blackwelder (1945) listed C. erythrogaster in the monotypic genus, in their catalogs/checklist. Gordon (1994) and Fürsch (1990a,b) placed Coeliaria in Exoplectrini, and González (2013) recorded C. erythrogaster from Paraguay.

The Brazilian species of Exoplectra were reviewed by Costa et al. (2008), who provisionally removed E. bernardinensis and E. luteicornis from the genus.

In this paper, Coeliaria is revised based on its external morphology and genitalia. One new species from Brazil and two new combinations are proposed, expanding the size and distribution records of the genus.

MATERIAL AND METHODS

The specimens examined were provided by the California Academy of Sciences, California, USA (CAS); Coleção Entomológica Pe. J.S. Moure, Universidade Federal do Paraná, Curitiba, Paraná, Brazil (DZUP); Museu de Ciências Naturais, Fundação Zoobotânica, Rio Grande do Sul, Porto Alegre, Brazil (MCN); Museé d’Histoire Naturelle de Lyon, France (MHNL); Museu Nacional do Rio de Janeiro, Rio de Janeiro, Brazil (MNRJ); Museu de Zoologia da Universidade de São Paulo, São Paulo, Brazil (MZSP); United States National Collection, Smithsonian Institution, Washington, DC, USA (USNM); and the Zoological Museum, University of Copenhagen, Denmark (ZMUC).

Parts that were dissected from specimens (mouthparts, antennae, legs, abdomen and genitalia) were stored in microvials with glycerin. The microvials were pinned together with the respective specimen. Photographs were taken using a Sony Cyber-shot (DSC-W300) digital camera coupled to a Zeiss Stemi SV6 compound stereomicroscope and a Zeiss Stereo Discovery Standard 20 microscope.

The terminology used in the descriptions follows Costa et al. (2008) and Krüger et al. (2016).

The labels of the type material are arranged in sequence from top to bottom, with the data for each label within double quotes (“ ”); slashes (/) separate the rows, and the information between brackets ([]) provides additional details recorded on the labels.

Type species. Exoplectra erythrogasterMulsant, 1850 (original designation).

Diagnosis. Coeliaria is a Neotropical genus that resembles ExoplectraMulsant, 1850, and GordonitaGonzález, 2013, by the angulation of the tibia. Coeliaria is distinguished from Exoplectra by the presence of a fovea in the hypomera; pronotum with the inner angles more prominent and emarginated. In Gordonita, the fovea of the hypomera is small and deep; the body is elongated and depressed. Coeliaria is distinguished from the other genera of Chnoodini by the following combination of characters: Body black or dark, without spots; dorsal surface pubescent; antenna 11-segmented; labrum truncated; hypomera with rounded fovea; tibia flat and angulated; abdomen with five visible sternites (females) or six sternites (males); abdominal postcoxal line incomplete, recurved, oblique line present.

Redescription. Body rounded or oval, convex, with yellowish or whitish pubescence, fine and dense, with punctuation fine and sparse. Integument brownish or black, with green, bluish, or bronze metallic reflections, without spots. Ventral surface reddish, brown, or black. Head black or brownish; clypeus merged with forehead, without fronto-clypeal suture, expanded laterally and with rounded front edge, distinctly emarginated; eyes divided by the gena (Figs 1, 2) partially covered by the pronotum. Antennae 11-segmented with conspicuous club (Fig. 3). Labrum transverse, truncate anteriorly (Fig. 4); mandibles asymmetric, robust with apex bifid (Figs 5, 6); maxillae with last segment of palpus distinctly securiform; labium with short bristles on ligule (Fig. 7). Pronotum transverse, narrower than elytra, anterior border emarginated with lateral margin straight, rounded above and subsinuous posteriorly. Hypomera with large, deep and rounded fovea (Fig. 9). Prosternal process with rounded apex, without carina (Fig. 8). Elytra expanded with projected humeral callus, with anterior margin truncate; elytral epipleuron wide, deeply excavated for reception of femoral apex, with carina parallel in the inner margin, curved at base (Fig. 10). Legs with relatively wide femora, excavated for reception of tibiae; tibiae flattened, with acute angulation on outer margin (Figs 11, 12); claws bifid. Abdomen with five (females) or six (males) visible ventrites, with descending post-coxal line, attached to the posterior edge of the first ventrite, with oblique line.

Male genitalia. Tegmen with penis guide and symmetrical parameres; penis slender, with developed penis capsule.

Female genitalia. Coxites elongated and sub-triangular; spermatheca C-shaped, simple.

Geographical distribution. Bolivia, Brazil and Paraguay (Fig. 55).

Remarks. Coeliaria erythrogaster, first described in Exoplectra, was characterized by presenting a fovea in the hypomera, differentiating it from all other species of Exoplectra. Since then it was considered the only species of Coeliaria. In addition to this character, C. erythrogaster has strongly expanded elytra, pubescence very dense and uniform, and is larger than the other species of the genus.

Biological data. Costa Lima (1950) published a report of the metamorphosis of C. erythrogaster larvae, and mentioned that it was covered by abundant waxy secretions. Mariconi and Zamith (1959, 1960) described the larvae and adult, as well as biological aspects of E. erythrogaster preying on Mimosicerya hempeli (Cockerell, 1899) (Hemiptera: Margarodidae) on the plant Cassia fistula Linnaeus (Fabaceae) in Piracicaba, São Paulo, Brazil. In their description of the adult they mentioned various bare areas, apparently with shorter and thinner pubescence. This description is consistent with Crotch (1874), who mentioned that recently collected specimens have gray pubescence, giving the impression of bare spots, which is very peculiar. According to those authors, the larvae are completely covered by white secretions that form a mass of conspicuous flaky wax, which extends 30 to 35 mm in length.

Remarks. Coeliaria bernardinensis was first described as Exoplectra bernardinensis, but is herein transferred to Coeliaria based on the presence of a deep fovea in the hypomera, which characterizes Coeliaria. It differs from the other species of Coeliaria by its small size and pattern of genitalia.

Geographical distribution. Brazil (Fig. 55).

Remarks. Coeliaria luteicornis shows a deep fovea in the hypomera, characteristic of Coeliaria; additionally, it has an oval body with whitish or yellowish pubescence. The male genitalia is similar to that of C. erythrogaster, but the female differs in the shape of the spermatheca. The most distinctive characteristic of this species is its oval body.

Description. Holotype female. Length 5.58 mm, width 5.25 mm. Body rounded, integument light brown, white pubescence (Fig. 47-50). Pronotum transverse, narrower than elytra, anterior margin emarginated yellowish, lateral margin rounded, posterior margin subsinuous (Fig. 49), hypomera with rounded fovea (Fig. 48). Prosternal process sub-quadrangular, apex without carinae, as long as wide (Fig. 48). Ventral color lighter than dorsal (Fig. 48). Scutellum brown. Elytra brownish, without spots (Figs 47-50); epipleura wide, narrowing to apex, with fovea for reception of femoral apex. Meso- and metaventrite brownish (Fig. 48). Legs brownish, flattened femora and tibiae, with acute angulation at the outer margin. Abdomen yellowish, with oblique line (Fig. 51). Genitalia symmetrical; coxites very elongated, three times longer than wide, styles with long bristles (Fig. 52). Spermatheca C-shaped, with sclerotized infundibulum (Fig. 53).

Male. Unknown.

Material examined. The holotype female is labeled as follows: Brazil, Santa Catarina “Nova Teutônia/SC, Brasil/XI. 1966/F. Plaumann col.”, “♀”, “HOLOTIPO/Coeliaria castanea” Churata-Salcedo & Almeida [red label], 1 specimen “DZUP/186709” [DZUP] (Fig. 54). The holotype is double mounted, and is in good condition (genitalia on microvial with glycerin).

Etymology. The species epithet, castanea, is a reference to the color pattern of this species.

Geographical distribution. Brazil (Santa Catarina) (Fig. 55).

Remarks. Coeliaria castanea sp. nov. resembles C. erythrogaster by having very conspicuous, deep and rounded fovea, but differs in the brownish color and by the shape of the female genitalia.
