Anthidulum rozeni  sp. nov.

( Figs. 1–7View FIGURES 1 – 12)

Comments and diagnosis. Head black with small yellow spot behind eyes ( Figs. 3–6View FIGURES 1 – 12). Tegula with semicircular light yellow macula; all terga with light yellow bands ( Figs. 4–6View FIGURES 1 – 12), medially interrupted on T 1 -T 3 ( Fig. 4View FIGURES 1 – 12). Male: clypeus, supraclypeal and lower paraocular area light yellow ( Fig. 1View FIGURES 1 – 12); T 7 with large lateral lobe ( Fig. 7View FIGURES 1 – 12). The semicircular macula of tegula and the T 7 with a large lobe are unique characteristics of this species.

Description. Holotype male.

Approximate body length 6.1 mm; forewing length 5.4 mm; head width 2.3 mm; eye length 1.5 mm. Color: Integument predominantly black except with yellow as follows: clypeus, lower paraocular area to just above antennal socket, supraclypeal area superiorly concave ( Fig. 1View FIGURES 1 – 12) and a small spot on vertex, just behind eyes ( Figs. 3, 5View FIGURES 1 – 12). Mandible with yellowish brown dorsal macula ( Fig. 1View FIGURES 1 – 12). Antenna brown. Mesoscutum with laterobasal light yellow band; scutellum with narrow distal yellow band, medially interrupted. Tegula brown with semicircular light yellow macula; wing membrane brown, darker at base and at costal margin ( Fig. 3View FIGURES 1 – 12). Legs blackened, fore and middle with irregular yellow maculae on base and apex of tibiae and yellowish ferruginous tinged on internal surface; middle leg with light yellow basal macula on external surface of basitarsus; hind leg with femoral apex and tibial base yellowish brown; basitarsus light yellow with brown apex. Terga black; T 1 with lateral light yellow bands widely separated; T 2 with narrow light yellow band medially interrupted; T 3 band little narrower than T 2 and weakly interrupted medially; T 4 -T 5 with narrow, complete bands, irregular on sides; T 6 with large band, anteriorly and posteriorly sinuous, and distal margin translucent ferruginous; T 7 light yellow with narrow black base and brownish distal margin ( Fig. 7View FIGURES 1 – 12). Sterna blackish basally, brown at middle and with translucent ferruginous margin.

Pilosity: Mostly white and sparse. Hairs up to longer than twice median ocellar diameter; pilosity plumose, conspicuous on sides of mesepisternum. Second sternum with apical fringe of long and plumose hairs; hairs shorter at middle; S 3 with sparse fringe laterally, denser at middle.

Punctures: Head and mesosoma densely punctate; punctures contiguous and slightly larger on mesosoma. Metasoma densely punctate, punctures shallower than on mesosoma.

Structure: T 7 with wide and flat lateral lobes, space between lobes as wide as lobe width ( Fig. 7View FIGURES 1 – 12).

Description. Paratype female. Differs from male in the following characteristics: Approximate body length 6.2 mm; forewing length 4.8 mm; head width 2.2 mm; eye length 1.5 mm. Color: Head almost completely black, except from small yellow spot on vertex, just behind eyes ( Fig. 2View FIGURES 1 – 12). Pronotal lobe with light yellow spot on apex ( Fig. 4View FIGURES 1 – 12). Fore and middle legs with yellowish brown area on tibial base ( Fig. 6View FIGURES 1 – 12). First tergum with large light yellow lateral band; T 2 -T 3 with narrower bands, closer than T 1; T 4 -T 5 with complete light yellow bands and T 6 black.

Pilosity and Punctures: As in male except by more conspicuous pilosity in paraocular area. Scopa light yellow.

Type material. Holotype male. PERU, Lima: “ PERU: Lima Dept./ Sta. Rosa de Quives,/ near Yangas. 1100m./ v- 28-29 - 96 / J. C. Rozen, A. Ugarte” (AMNH). Paratypes: one male and one female of with the same data of holotype (AMNH); one male with the same data of holotype (DZUP); one male with the same data, except by date ‘ v- 28-96 ’ (AMNH); one male without metasoma: “ PERU: Lima Dept./ Ricardo Palma, V- 9-96 / J. C. Rozen, A. Ugarte” (AMNH) and one female with the same data (DZUP); one male: “ PERU: Lambayeque/ Dept. 20 km E. Olmos/ v- 21-96 500–1000m./ J. C. Rozen, A. Ugarte” (AMNH).

Etymology. The specific epithet honors Dr. Jerome G. Rozen, American Museum of Natural History, New York.

Variation. All male paratypes have a yellow spot on the pronotal lobe. In the paratype male collected from Lambayeque, the yellow maculae of mesosoma and metasoma are larger than the remaining specimens.

Comments. Anthidulum rozeni  differs from all other species in the shape of T 7, by its wide lateral lobes, separated by narrow emargination. All other species have narrower lateral lobes, widely separated by more than three times the base of lobe width. Moreover, the new species has a small yellow spot behind the eyes while all other species have a yellow or ferruginous postocellar band extending across the vertex. The two other species of Anthidulum  known from Peru, Anthidulum lamasi Urban, 2003  and Anthidulum clausi Urban, 2003  , have the vertex with a yellow postocellar band and the mesoscutum with a band along the anterior and lateral margins. Anthidulum lamasi  has the supraclypeal area black, T 4 -T 5 almost totally yellow and A. clausi  has a large yellow spot on the mesepisternum laterally and T 4 -T 7 are predominantly yellow.
