Antrops sierrazulensis sp. nov.

( Figs. 163 , 226 )

Description. Occiput and posterior part of frons black, rest of head orange. Occiput covered with microtomentum, frons with frontal triangle and interfrontal plates mostly shiny, microtomentum around bases of postvertical bristles, microtomentum on orbital plates reaching bases of interfrontal setae, face mostly shiny, microtomentum on lunule and below base of antenna, gena mostly shiny with microtomentum along ventral margin and in a spot below eye. Subvibrissal and anterior genal bristles about 0.3X length of vibrissa.

Halter white.

Trochanters and fore tarsus brown, mid and hind tarsi yellow. Hind tibia with 2 ventroapical bristles.

Sternites heavily sclerotized, black, covered with microtomentum in male.

Male postabdomen: Sternite 5 with curved lateral margins, widest medially, posterior corners projecting strongly and bearing tufts of long setae, posterior margin emarginated forming two shallow lobes, anterior apodeme about as long as external portion, pointed, with a dorsal keel. Surstylus scooped. Pregonite small, distinct. Postgonite with lobes short, well separated, anterior lobe rounded, posterior lobe pointed. Basiphallus with short, broad epiphallus, short, transparent preepiphallus. Distiphallus with long, curved, spinose dorsal tube ( Fig. 163 ).

Female postabdomen: Tergites 6–7 and sternites 6–7 wider than long, sclerotized along anterior and lateral margins only. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 with a deep cleft in anterior margin, strongly pinched medially, distal half covered with microtomentum. Epiproct with short anterior arms, shiny, with 1 pair of setae. Cerci broad. Sclerites of sternite 8 broad, subrectangular, pinched and sculptured medially, distal third with microtomentum. Hypoproct subrectangular, weakly sclerotized. Spermathecae barrelshaped, about 1.2X longer than wide, with an apical invagination, sclerotized duct about as long as spermathecae.

Type material. Holotype ♂: ECUADOR: Napo: SierrAzul Res. , 14 km W Cosanga, 2200 m, dung baits, 8–11 May 2002, M. Buck, debu00195169 ( QCAZ) . Paratypes: same data as holotype (3 ♀, DEBU) ; as above but 10 May 2002, S.A. Marshall (1 ♂, DEBU) ; as above but treefall, yellow pans, 10–11 May 2002, Marshall & Paiero (1 ♀, DEBU) ; Bolivar: Hda. Talahua , 3100 m, 29 Apr 1939, F.M. Brown (1 ♀, AMNH) ; Loja: Podocarpus Natl. Pk., Cajanuma, Bosque Nublado trail, 3000 m, Malaise , 16 Feb–5 Mar 2009, M. Pollet & A. De Braekeleer (2 ♀, DEBU) .

Comments. This species is named after the type locality, the Reserva Ecológica SierrAzul, a remarkable cloud forest reserve with many interesting archiborborine species.
