sp. nov.

Acrogymnidia catalina Malagón-Aldana  sp. nov. ( Fig. 6View FIGURE 6 a-k)


Female: Length 8.5 mm. Antennal length 2 × head width; scape length 2.5 × pedicel length; scape length 2.3 × its width; pedicel as long as wide; in frontal view, lower interocular distance same as eye length; distance between lateral ocelli subequal to distance between eye and lateral ocellus, and 1.2 × distance between lateral ocellus and posterior margin of head; malar space broad, 0.8 × diameter of median ocellus; clypeus width 2.5 × its length. Metabasitarsus length 0.57 × of tarsus length. Fore wing with cells 1R1 and 1Rs fused, without vein Rs between them; 2Rs cell slightly longer on Rs than in M ( Fig. 6dView FIGURE 6). 1 st valvulae broad, tapering gradually toward apex, slightly curving at middle ( Fig. 6hView FIGURE 6); lamnium with 20 annuli and sawteeth; annuli of uniform width, each annulus bordered anteriorly by short row of ctenidia ( Fig. 6jView FIGURE 6); wall of each annulus with spiniform microtrichia in patches of three or four ( Fig. 6kView FIGURE 6); sclerora ( Ross, 1945) with conspicuous marginal campaniform sensilla, tubular, each tapering ventrally; walls of sclerora with single microtrichium; each sawtooth widening distally with semicircular projection anteriorly, without distinct serrulae ( Fig. 6iView FIGURE 6). Third valvula with apicolateral short lobes (= scopae s. Ross 1937), in dorsal view shorter than apex of valvula, with abundant hairs laterally ( Fig. 6jView FIGURE 6). Color. Head black with interantennal carina, supraclypeal, malar area, clypeus, labrum, and palpi yellow; antenna with scape and pedicel yellow, flagellum black; mandibles yellow proximally, brown distally ( Fig. 6eView FIGURE 6). Thorax yellow, with black spots in median and lateral lobes of mesoscutum, and in ventral areas of mesepisternum; mesoscutellum and axillae black ( Fig. 6a,bView FIGURE 6). Legs yellow; fore and mid legs with tarsomeres brownish yellow; hind legs with distal 2/3 part of tibia, tarsus and pretarsus black. Wings black with yellow discal band, including pterostigma ( Fig. 6dView FIGURE 6). Abdomen yellow with three terminal segments and third valvulae black ( Fig. 6fView FIGURE 6).

Male: Unknown.

Holotype: ♀. COLOMBIA. Bolívar , Santa Catalina, Hacienda el Ceibal. 20m. 10°36’N, 75°17’W. 01-Oct- 1999. E. Flórez leg., deposited at ICN-MHN, ICN-095922.GoogleMaps 

Etymology: The species name refers both, to the sampling location of the specimen and to the “india Catalina”, the historical and symbolic indigenous woman of this country region during times of Spanish conquest.

Remarks: The color pattern of the holotype is unique, with a yellow band in both fore- and hindwing. The 1 st valvulae of A. catalina  and A. surinamensis  are similar; however in A. surinamensis  the 3 rd valvulae have apicolateral lobes much longer, beyond the median apex of 3 rd valvulae. The occurrence of A. catalina  is the northernmost record for the genus (in the Caribbean region of Colombia) in South America; the closest records are of A. udata  from southern Ecuador, and A. surinamensis  from Suriname.
