Anthidulum rozeni sp. nov.

( Figs. 1–7 )

Comments and diagnosis. Head black with small yellow spot behind eyes ( Figs. 3–6 ). Tegula with semicircular light yellow macula; all terga with light yellow bands ( Figs. 4–6 ), medially interrupted on T1-T3 ( Fig. 4 ). Male: clypeus, supraclypeal and lower paraocular area light yellow ( Fig. 1 ); T7 with large lateral lobe ( Fig. 7 ). The semicircular macula of tegula and the T7 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. 1 ) and a small spot on vertex, just behind eyes ( Figs. 3, 5 ). Mandible with yellowish brown dorsal macula ( Fig. 1 ). 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. 3 ). 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; T1 with lateral light yellow bands widely separated; T2 with narrow light yellow band medially interrupted; T3 band little narrower than T2 and weakly interrupted medially; T4-T5 with narrow, complete bands, irregular on sides; T6 with large band, anteriorly and posteriorly sinuous, and distal margin translucent ferruginous; T7 light yellow with narrow black base and brownish distal margin ( Fig. 7 ). 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; S3 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: T7 with wide and flat lateral lobes, space between lobes as wide as lobe width ( Fig. 7 ).

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. 2 ). Pronotal lobe with light yellow spot on apex ( Fig. 4 ). Fore and middle legs with yellowish brown area on tibial base ( Fig. 6 ). First tergum with large light yellow lateral band; T2-T3 with narrower bands, closer than T1; T4-T5 with complete light yellow bands and T6 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 T7, 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, T4-T5 almost totally yellow and A. clausi has a large yellow spot on the mesepisternum laterally and T4-T7 are predominantly yellow.
