Comments

This species was placed in Pseudaugochlora by Moure & Hurd (1987) without examining the type material. More recently, Moure (pers. comm.) was able to study the type series and associated the species with Thectochlora .

Similarly to T. alaris , females of T. basiatra also show conspicuous variation in body size; for example, the maximum head width of specimens from Vila Velha, Paraná, varies from 1.78 to 2.02 mm. As mentioned under T. alaris , the females of these two species could not be distinguished on external features. Therefore, a diagnosis is presented only for males.

Based on male features, T. basiatra groups with T. hamata sp. nov. and T. mixta sp. nov. The male antennae in these three species has a small glabrous area in the middle of each flagellomere (character 04- 1 in the cladistic analysis). This kind of pubescence pattern is found in other halictine bees; as an example, McGinley (1986) has named these areas as oval tyli in Lasioglossum (Halictini) . In the phylogenetic analysis, T. basiatra came out as sister-group of T. hamata due to the non-produced posterior border of the male S4 (character 13, Figs. 16 and 18 ).

Male diagnosis

Antennal flagellomeres II to XI subequal in length, short pubescence restricted to basal and apical one-third of the flagellomeres, leaving small glabrous areas in the middle of each flagellomere; face wider than long; fore leg trochanter without dorsal hook; S4 disc with sparse and short pubescence, medially with a tuft of very short setae.

Type material

The type series of Augochloropis basiatra deposited at ZMHB is composed of one male and two females. The male specimen, bearing the following labels “Asuncion,\ Paraguay \ Vila Morra\ 9.XI.05 \ J. D. ANISITS” “Augochlor\ opsis ba-\ siatra n\ Strand det.” “ Type ” “Zool. Mus.\ Berlin” “ Thectochlora \ alaris [male simbol]\ ( Vachal, 1904)\ Pe. J. S. Moure 1996” is here designated lectotype in order to stabilize the taxonomy of the group. The following label was added: “ LECTOTYPE \ Augochloropsis \ (Pseudaugochloropsis) basiatra \ Strand, 1910 \ desig. Gonçalves & Melo, 2006”. Paralectotypes: 1 female ( ZMHB), “Asuncion,\ Paraguay \ Vila Morra\ 30.XI.04 \ J. D. ANISITS” “Augochlor\ opsis ba-\ siatra n\ Strand det.” “ Type ” “Zool. Mus.\ Berlin”; 1 female with same data except “ 19.XI.05 ” and without any type label. The integument color of the lectotype is somewhat faded; it also lacks the left antenna beyond the 1st flagellomere.
