Diagnosis.

This species is known only from the male. It can be distinguished from other Argentinean species of Schonnherria by the following combination of characters: small body size (body length 17.0-17.7); integument dark brown to black throughout, at most with faint metallic highliths on metasomal terga; compound eyes not enlarged, parallel or nearly so (Fig. 8); metasomal terga uniformly punctate, punctures separated by 1-2 times a puncture width, with distinctly long (≥ 2.0 OD) setae on discs (Fig. 20).

Male.

Body length 17.3 (17.0-17.7); head length 3.5 (3.5-3.6); head width 4.4; mesosoma width 6.0; metasoma width 6.7 (6.6-6.8); forewing length 14; forewing width 3.5 (3.4-3.6). Coloration. Integument dark brown to black except tarsi light reddish brown and cream to yellow maculations as follows: outer surface of mandible (except margins), clypeus, supraclypeal area basally, and paraocular area (except on upper one-third) (Fig. 8). Wings sybhyaline, yellowish, with weak coppery highlights. Pubescence. Long, dense, predominantly yellowish, setae dark brown to black on vertex, metafemur basally, dorsal surface of metatibia, and discs of T2-T7 (variably mixed with yellowish setae) (Fig. 20). Sculpturing. Integument largely imbricate among punctures, nearly smooth and shiny on outer surface of mandible, labrum, maculate areas of face, and discs of mesoscutum and mesocutellum. Upper paraocular area, frons, and interocellar area with coarse, contiguous punctures; vertex and gena with punctures sparser than on upper paraocular area. Discs of mesoscutum and mesoscutellum largely impunctate, otherwise punctures shallower than and about as dense as those on vertex. Discs of metasomal terga uniformly punctate, setiferous punctures circular to ovoid, separated by 1-2 times a puncture width, distal margins impunctate (Fig. 20); sterna more densely punctate than on terga. Structure. Head broader than long (1.2-1.3:1); compound eyes not enlarged, parallel or nearly so (Fig. 8); proportion of upper to lower interocular distance 0.9-1:1; upper interocular distance 6.3 –6.9× OD; middle interocular distance 2.60; distance between median ocellus and posterior margin of vertex 2.6-2.7 OD; orbitoccipital distance 0.60; lateral ocelli on supraorbital line; interocellar distance to ocelocular distance 1.2-1.3:1; interocellar to ocelloccipital 0.5-1.1:1; ocellocular to alveolocellar 0.5-0.6:1; orbitoccipital to ocellocular 1.2 -1.5:1; alveolocular to interalveolar 1.1-1.2:1; clypeoalveolar distance 1.5 times longitudinal diameter of antennal socket; clypeocellar distance to distance between median ocellus and posterior margin of head 1.4-1.5:1; frontal carina elevated, short 0.8-0.9; clypeus broader than long, 0.6:1; proportion of length of scape, pedicel and F1-F4: 2.3:0.4:1:0.4:0.5:0.6, respectively. Mesoscutellum nearly flat, exposed, along same inclined plane with metanotum and base of propodeum; metatibia apically swollen on inner surface. Genitalia as in Figs 26, 31, 36, 41.

Female.

Unknown.

Distribution.

This species is known only from Brazil and the province of Misiones in Argentina, the latter area included in the Paranaense biogeographic province (Fig. 58).

Comments.

Schrottky (1912) suggested that Xylocopa chrysopoda may be the male of Xylocopa pulchra , a species currently known from the female sex. As for Xylocopa bambusae , these two species are rarely collected and are currently known from a limited number of specimens. We did not collect nor examine specimens of Xylocopa chrysopoda from Argentina captured in the last 100 years.
