Xylocopa mendozana Enderlein, 1913a: 130 . Syntype: 3♀, 3♂ see Enderlein 1913:131–132, deposited at MIZ. Type locality: Mendoza, Argentina. (Not examined)

Xylocopa (Neoxylocopa) mendozana, Hurd & Moure, 1963: 151 .

Diagnosis. The female of this species can be distinguished from other Argentinian large carpenter bees by the following combination of characters: integument black; T2 and basal third of T3 with median pubescence very short, 0.2–0.4 times MOD and barely protruding from the insertion puncture; rest of T3 with hairs 3–4 times longer than those on T2; supraorbital area wide (3.5–4.1 times DOM). The male can be easily recognized by T2–T3 with median pubescence very short, the hairs barely protruding from the insertion puncture, T2 densely puncture, and metasomal terga with brown apical bands. Females of X. mendozana can be distinguished from all other Argentinian Xylocopa by the punctation and pubescence on T2–3.

Female. Approximate body length 27 (25–29.3); head length 6.6 (6.2–7); head width 7.6 (7–8.2); mesosoma width 9.6 (8.8–10.4); metasoma width 11 (10.4–11.8); forewing length 22.7 (21–24.3); forewing width 6.6 (6.4– 6.8). Coloration. Integument predominantly black, except scape brown; tegula dark. Wing dark brown with violetgreen iridescent. Pubescence. Black, head with abundant hairs scattered and short in vertex and median and inner part of gena ( Fig. 5 ). Mesosoma with abundant plumose hairs, except hairless on disc and posterior area of scutum. Metasoma with long hairs laterally; T1 with plumose hairs; T2 and basal third of T3 with median pubescence very short, 0.2–0.4 times MOD, the hairs barely protruding from insertion puncture; rest of T3 with hairs 3–4 times longer than T2; T4–T6 with long hairs (5–6 times longer than in T2) ( Fig. 14 ). Punctation. Head regularly and densely punctate; dispersed on vertex, supraorbital area and median and inner part of gena. Median longitudinal area of vertex smooth well defined. Scutum densely punctate, except impunctate on disc and posteriorly. Metasomal terga regularly and densely punctate, T1–3 finely punctate and T4–6 with large punctures. Structure. Head broader than long (proportion 1–1.2:1); inner orbits incurved, proportion of upper to lower interocular distance 1:1; middle interocular distance 5–5.8 mm. Vertex broad, distance ocelloccipital (to median ocellus) 4.3– 4.8 times ocellar diameter (median ocellus); orbitoccipital distance long 1.8–2.3 mm. Lateral ocelli below supraocular line, proportions of interocellar to ocelocular distance 0.6–0.8:1, interocellar to ocelloccipital 0.4– 0.5:1, ocellocular to alveolocellar 1–1.2:1, orbitoccipital to ocellocular 1.4–1.6:1, alveolocular to interalveolar 1.2– 1.3:1. Proportion of clypeocellar distance to distance between median ocellus and posterior margin of head (0.7– 0.8:1). Frontal carina moderately elevated, long 1.2–1.3, apex reaching the middle portion between upper and lower level of the antennal sockets. Clypeus broader than long (proportion 2.2–2.3:1); proportion of length of scape, pedicel and first four flagellomeres 2.9–3.1:0.2–0.3:1:0.3–0.4:0.4–0.5:0.4–0.5. Labrum broader than long, with three basal protuberances, the median most developed, the laterals cariniform. Scutellum gently rounded as seen in profile. Apex of basitibial plate beyond length middle of tibia, asymmetrically bifid, posterior apical lobe rounded and shorter than anterior lobe.

Male. As in the female, except as follows: Approximate body length 25 (21.7–26.7); head length 4.9 (4.6–5.3); head width 6 (5.6–6.4); mesosoma width 9.5 (9–10); metasoma width 11.2 (10.2–12.5); forewing length 21.3 (18.7–23.3); forewing width 5.7 (5.2–6.2). Coloration. Integument predominantly brown yellowish, except dark brown as follows: edges of clypeus, subantennal sulcus, middle and apical portion of mandible, coxa, trochanter, femur and propodeum. Apical bands on metasomal terga brown. Tegula yellowish, otherwise translucent brown. Wings hyaline, yellowish with golden iridescent. Pubescence. Yellowish (varying from ferruginous to yellows); T6–7 with yellowish to ferruginous pubescence ( Fig. 25 ). Head with long hairs, scattered on median area of clypeus, superior part of paraocular area and median and internal portion of gena ( Fig. 19 ); scutellum hairless; pubescence of the ventral surface of the posterior tibia restricted to the base ( Fig. 31 ). T2–T3 with median pubescence very short; T4–7 with long and abundant hairs (5–6 times longer than in T2–3). Sculpturing. Head, median longitudinal area of clypeus impunctate. Metasomal terga regularly and densely punctate, T2–3 finely punctate and T1, 4–6 with large punctures. Structure. Head broader than long (proportion 1.2–1.3:1); proportion of upper to lower interocular distance 1–1.1:1; upper interocular distance 5.8–7 times MOD; middle interocular distance 4.2– 3.5 mm. Distance ocelloccipital (to median ocellus) 2.3–2.9 times MOD, orbitoccipital distance longer 1.1–1.4 mm. Proportions of interocellar to ocelocular distance 0.9–1:1, interocellar to ocelloccipital 0.6– 0.8:1; ocellocular to alveolocellar 0.8–1.1:1; orbitoccipital to ocellocular 1.5–1.8:1; alveolocular to interalveolar 1.1–1.4:1. Proportion of clypeocellar distance to distance between median ocellus and posterior margin of head (1– 1.3:1). Frontal carina long 0.9–1.2 mm, apex scarcely exceed upper level of antennal sockets. Clypeus broader than long (proportion 1.6–1.8:1). Proportion of length of scape, pedicel and first four flagellomeres 2.5–3:0.2– 0.4:1:0.3–0.5:0.4–0.5:0.4–0.5. Labrum broader than long with median basal triangular process well defined. Genitalia as in figures 37, 43, 49 and 55.

Variations. Like other black species, this species does not show considerable variation in the color pattern. However, some female specimens have integumental dark brown color in the following areas: legs, genae, scutellum and metasomal terga.

Comments. The syntype (s) of X. mendozana could not be examined; the type series were borrowed to P.J. Moure in the 1960´s and they were never returned to MIZ (Tomasz Huflejt, pers. inf.). As we have not examined the syntype series, ours interpretation of this species is based on the original description.

Distribution ( Fig. 59 ): ARGENTINA: Catamarca, Córdoba, La Pampa, La Rioja, Mendoza, Río Negro, Salta, San Juan, San Luis y Santiago del Estero. Its distribution comprises principally the Monte and part of the Prepuneña, Chaqueña, Patagonia and Pampeana biogeographic provinces and the southernmost record of this species is North of Río Negro province, approximately parallel 40°. Ascher & Pickering (2011) recorded this species for Bolivia.
