Antrops variegatus sp. nov.

( Figs. 62–63 , 210 )

Description. As described for A. anovariegatus . Face mostly shiny with microtomentum covering lunule and below antenna. Pale areas on thorax reddish rather than dark reddish brown. Shiny patch on anepisternum larger, about 0.5X length and 0.7X height of sclerite.

Male postabdomen: Sternite 5 with curved lateral margins, widest at about two-thirds length, anterior apodeme broad, about 1.4X length of external portion ( Fig. 63 ). Surstylus scooped, with a shallow projection along posterior margin. Pregonite distinct. Postgonite with lobes well separated, anterior lobe short and rounded, posterior lobe longer and pointed. Basiphallus with short broad epiphallus and preepiphallus, preepiphallus transparent. Distiphallus with curved spinose dorsal tube flanked by two spike-like sclerites ( Fig. 62 ).

Female postabdomen: Tergites 6–7 slightly wider than long, with anterior and lateral margins sclerotized, tergite 6 also with a medial stripe sclerotized, anterior margin shiny. Sternites 6–7 entirely sclerotized. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 longer than wide, anterior margin emarginated, covered with microtomentum. Epiproct with long anterior arms, distal portion covered with microtomentum, with 2 pairs of setae. Cerci long. Sclerites of sternite 8 pointed anteriorly, pinched medially, distal half covered with microtomentum. Hypoproct subrectangular, with a curved unsclerotized band medially, covered with microtomentum except anterior margin. Spermathecae barrel-shaped, about 1.2X longer than wide, without invaginations, sclerotized duct about 1.5X longer than spermatheca. One dissected female with 32 eggs.

Type material. Holotype ♂: ECUADOR: Pichincha: Tandapi , 35 km E, 24 Jun 1975, S. & J. Peck, debu01039326 ( QCAZ) . Paratypes: same data as holotype (5 ♂, 1 ♀, DEBU, QCAZ) ; as above but bamboo, moss (1 ♀, DEBU) ; Tandapi , 34.5 km E, 2835 m, bamboo shrub, dung trap, 24–29 Jun 1975, S. Peck (1 ♂, 2 ♀, DEBU) ; Napo: 7 km S Baeza , 2000 m, dung trap, 25 Feb 1979, H. & A. Howden (9 ♂, 20 ♀, USNM) ; as above but 22 Feb 1979 (4 ♂, 1 ♀, USNM) ; as above but 23 Feb 1979 (2 ♀, USNM) ; E of Papallacta , 2600 m, 12 Jan 1971, [no collector] (1 ♂, USNM) ; as above but 12–14 Jan 1971 (1 ♂, USNM) .

Comments. The species name refers the the varicoloured thorax. This species is quite similar to A. anovariegatus sp. nov., but appears to occur at lower elevations. See that species for further discussion.
