ABSTRACT

The genus Myllaena Erichson, 1837, of the tribe Myllaenini Ganglbauer, 1895, is recorded from Brazil for the first time. A new species, Myllaena brasiliensis sp. nov., is described and illustrated; it is closely related to the insomnis species group, described from the Nearctic region. A short diagnosis of the genus and an annotated catalog of Myllaena species from the Neotropical region are also provided.

Keywords: Brazil; distribution; rove beetles; taxonomy.

RESUMO

O gênero Myllaena Erichson, 1837, da tribo Myllaenini Ganglbauer, 1895, é registrado pela primeira vez no Brasil. Uma nova espécie, Myllaena brasiliensis sp. nov., é descrita e ilustrada; esta espécie é proximamente relacionada ao grupo de espécies insomnis, descritas da região Neártica. Uma breve diagnose do gênero e um catálogo comentado das espécies de Myllaena da região Neotropical são também fornecidos.

Palavras-chave: Brasil; distribuição; estafilinídeos; taxonomia.

The tribe Myllaenini Ganglbauer, 1895 is a monophyletic taxon embracing a group of species whose position appears to be solidly established within the 'higher' Aleocharinae (Ahn & Ashe 2004; Ashe 2005). Myllaena Erichson, 1837 is a small genus with some 205 species worldwide (Newton & Thayer 2005), and 30 species recorded from the Neotropical region (Newton et al. 2005). The species occur in riparian habitats predominantly associated with edges of streams, rivers and lakes (Klimaszewski 1982).

In the present paper, a new species of Myllaena is described and illustrated and the genus is for the first time recorded in Brazil. A short diagnosis of the genus and an annotated catalog of Myllaena species from the Neotropical region are also provided.

MATERIAL AND METHODS

Dried specimens were first macerated in boiling water for five minutes and then cleared in boiling 10% KOH for two minutes. The micro dissections were carried out under the stereoscopic microscope, Zeiss Stemi SV6, and the drawings were made using the same equipment and Zeiss Standard 20 optical microscope with attached drawing tube. Photographs were taken using a stereoscopic microscope Leica MZ 16 with a Leica DFC 500 digital camera. The images were captured with computer software IM 50 (Image Manager) and combined using the image processing software Auto-Montage Pro 5.03.0040. The final versions of drawings and photographs were prepared using Adobe Photoshop software, version 7.0.

Measurements were done using the micrometric ocular in the stereoscopic microscope Wild M5. The following abbreviations were used: BL, body length (from anterior margin of head to posterior margin of tergite VIII); BW, body width (across humeral region); PL, pronotum length (maximum); PW, pronotum width (maximum); EL, elytra length (maximum).

The terminology used in the text is adopted from Blackwelder (1936) and Klimaszewski (1982).

Specimens are deposited in the Coleção de Entomologia Pe. J.S. Moure, Departamento de Zoologia, Universidade Federal do Paraná, Curitiba, Brazil (DZUP); Museu Nacional do Rio de Janeiro, Rio de Janeiro, Brazil (MNRJ); Museu de Zoologia, Universidade de São Paulo, São Paulo, Brazil (MZSP); Museu de Ciências Naturais da Fundação Zoo-Botânica do Rio Grande do Sul, Porto Alegre, Brazil (MCNZ); Field Museum of Natural History, Chicago, United States (FMNH); and the Insectarium R. Martineau, Laurentian Forestry Centre, Quebec, Canada (LFC).

Myllaena brasiliensis sp. nov.

(Figs. 1-16)

Type material. Holotype (male): BRAZIL, Rio Grande do Sul, Rio Grande, Praia do Cassino, 20-I-1993, Gianuca col. (DZUP). Paratypes: same locality and collector, 06-I-1993 (1 male and 2 sex undetermined, FMNH), 20-I-1993 (2 sex undetermined, DZUP), 27-I-1993 (2 males, 1 female and 1 sex undetermined, DZUP; 2 sex undetermined, MCNZ; 1 female and 1 sex undetermined, MZSP; 1 female and 1 sex undetermined, MNRJ; 1 male, 1 female and 3 sex undetermined, LFC), 10-II-1993 (1 male and 2 females, DZUP).

Description. BL: 1.40-1.74 mm; BW: 0.56-0.64 mm.

Head and abdomen dark brown (segments III-VI); antennae, mouthparts, pronotum, elytra, legs and apex of abdomen (segment VII-VIII) light brown (Figs. 1, 2). Head about as long as wide and without differentiated neck. Eyes large, covering most of the visible lateral region of head. Antennae reaching the base of elytra, scape broad and slightly elongate, pedicel the longest, articles 3-10 elongate but gradually decreasing in length toward antennal apex, the last article somewhat clavate (^{Fig. 3}). Mentum with two short anterior teeth medially (^{Fig. 8}). Pronotum convex, wider than long (^{Fig. 9}) (PW/PL: 1.44), widest behind the middle, posterior margin sinuate. Elytra wider than long (BW/EL: 1.54). Hind wings fully developed. Abdomen with numerous prominent macrosetae. MALE. Tergite VIII elongate, broadly rounded apically and slightly pointed medially (Fig. 11), with four pairs of prominent setae distributed latero-posteriorly. Sternite VIII elongate and rounded posteriorly with four pairs of prominent setae distributed latero-posteriorly (Fig. 12). Median lobe of aedeagus approximately round, moderately sized bulbus, and narrowly elongate tubus with truncate apex (Fig. 14). Internal sac with flagellum as long as the median lobe (Figs. 14, 15). Paramere as illustrated (Fig. 14). FEMALE. Sternite VIII and tergite X similar to those of male. Spermatheca with pitcher-shaped tubular capsule, median invagination moderately deep, stem long with multiple coils (Fig. 16).

Etymology. The specific name derives from Brasil, the name of the country where the type series was discovered.

Distribution. Southeastern Brazil (Rio Grande do Sul: Rio Grande: Praia do Cassino).

Remarks. The shape of the aedeagus (Figs. 14, 15) and the shape of the spermatheca (Fig. 16) of Myllaena brasiliensis sp. nov. are similar to those of the insomnis species group described from the Nearctic region (M. audax Casey, 1911; M. brevicollis Casey, 1911; M. decreta Casey, 1911; M. hopkinton Klimaszewski, 1982; M. insomnis Casey, 1911; and M. magnolia Klimaszewski, 1982). The morphology of the median lobe of the aedeagus and the multiply coiled stem of the spermatheca are matching characteristics of the insomnis group and therefore we regard our newly described species as affiliated to this group.

Many species of Myllaena from the Neotropical region are poorly diagnosed and illustrated. This raises the need of revising all species of this group from the entire region. We did not hesitate to describe M. brasiliensis as a new species because it is the only known species of this genus from all of Brazil.

Note: the record of M. parvicollis Kraatz, 1859 from Chacabuco, Argentina by Lynch (1884) is in fact M. lynchi Fauvel, 1888 (Fauvel 1888). But M. parvicollis was subsequently recorded from Rio Negro, Argentina by Scheerpeltz, 1972 (Dr Alfred F. Newton, FMNH, pers. comm.).

30. Myllaena serrano Klimaszewski, 1982

Myllaena serrano Klimaszewski 1982: 210 [original description]: 204 [map distribution (error: legend)]: 209, 240 [illustrations]. Navarrete-Heredia et al. 2002: 191 [in checklist from Mexico].

Acknowledgments. We wish to thank to Dr. Alfred F. Newton (FMNH) for valuable information about Myllaena species from the Neotropical region; Dr. Cibele S. Ribeiro-Costa (UFPR) and two anonymous reviewers for discussion and suggestions about this paper; Dr. Carla de Lima Bicho (UFPR) for providing the specimens of M. brasilienisis sp. nov..; the Biological Collection Network of Paraná (Taxon-line, UFPR) for the photographs; and the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) for the Scholarships to the first author.
