Bortolanza, Mariza, Carvalho, Claudio José Barros De & Lara, Ana Paula Conter, 2006, A new species of Coenosopsia Malloch (Diptera, Anthomyiidae) from southern Brazil and a reappraisal of the cladistic relationships of the genus, Zootaxa 1242, pp. 37-52 : 40-43

Coenosopsia albuquerquei Bortolanza and Carvalho , sp. nov.

( Figs. 1–4 )

Diagnosis

This species is closely related to C. ferrari but can be distinguished by surstili width, size of pregonite and aedeagus and by other characters provided in the key.

Description

Male. Measurements: 2.29–2.98 mm (body length), 2.36–3.3 mm (wing length). Colour: frons dark brown on upper half; lower half orange­yellow. Ocellar triangle dark brown with silver pollinosity. Gena yellow with silver pollinosity. Palpus, proboscis and antenna brown.

Legs light brown, lighter at base of hind femora. Abdomen brown with yellow maculae at lateral apex of tergites 2–4. Sternite 1 setulose with robust setulae. Terminalia (Figs. A–D): Epandrium in lateral view, with dense robust setulae at lower anterior portion. Cercal plate with downwardly oriented median lobe, tapering to a point at the apex. Surstyli elongate, left surstylus very slender. Pregonite with fine setulae on the anterior apex ( Fig. 2 A).

Female. Measurements: 2.81–4.26 (body length), 2.93–4.37 (wing length).

Remarks

C. albuquerquei and C. ferrari share fine setulae on the anterior apex of the pregonite, however these setulae were unnoticed in the description of C. ferrari (see Nihei & Carvalho 2004). Females cannot be distinguished from females of C. ferrari .

Geographical distribution

Brazil.

Comments on habitat of the species

C. albuquerquei was collected in Malaise traps in two preserved areas of Araucaria moist forest in southern Brazil ( Veloso & Góes­Filho 1982), in a temperate climate ( Maack 1981). Both areas are in the second plateau of the state of Paraná. Most specimens were collected at the type­locality, a biological reserve, in Telêmeco Borba, of about 200 hectares at 750 m elevation. Two specimens collected in Ponta Grossa were found in the forest edge (25º13’5.0"S, 50º2’26.9"W) and one within the forest (25º13’2.9"S; 50º2’14.1"W), the two sites separated by 400 m. Araucaria angustifolia (Bertol.) is the dominant tree, with “campos limpos” and gallery forest along streams ( Marinoni & Dutra 1993). The gallery forest is similar to that found on the Iguassu River. Both conservation units have been very degraded due to deforestation ( Marinoni & Dutra 1993).

Reproductive biology

Some species of Coenosopsia are larviparous ( Michelsen 1991; Nihei & Carvalho 2004), and in our sample, we found eggs, and no larvae, in one gravid female of C. albuquerquei .
