description: Abbrosoga errata Caldwell
(Figs 1, 2, 4)
Type locality. Toro Negro Mts., Puerto Rico.
Amended diagnosis. Thorax with narrow pale median vitta, scutellum pale (Fig. 1A). Forewing embrowned between apices of Sc and RA (Fig. 1C). Frons relatively narrow (frons l:w ratio ~1: 2.15–2.37). Male gonostyli distally with ventral hook in lateral view; aedeagus with single ventral process (Figs 2B, 4A), anal tube dorsocaudally without projection in lateral view.
Amended description. Color. General color stramineous to brownish-yellow, carinae concolorous to body; eyes dark (Figs 1A, 1C). Pro- and mesonotum with narrow pale median vitta, darker laterally; pronotum with small dark spot on either side of median carinae. Mesonotum pale medially, including scutellum, darker laterally. Macropterous wings (Fig. 1C) clear with distal cubital area diffusely fuscous and a small spot on the commissural margin at apex of claval veins and a second on the leading margin between the apices of the Sc and RA. Hind wings hyaline.
Structure. Length male 3.6–3.8 mm with wings (reported as 3.8 for male and 4.2 mm for female in Caldwell & Martorell, 1951); ~2.2 (n=1) without wings. Head. Head (dorsal view, including eyes) just narrower than pronotum (Fig. 1A); in lateral view, slightly projected anteriorly. Vertex with conspicuous carinae (median carina weak), length 0.30 mm, width 0.24–0.26 mm; posterior margin truncate. Frons (Fig. 1B) widest between eyes (0.26–0.27 mm), weakly narrowed dorsally (0.22 mm) and ventrally (0.18–0.20 mm), length 0.56–0.64 mm; l:w ratio 1: 2.15– 2.37; median carina forking near fastigium. Clypeus 0.29–0.30 mm, with median carina. Antennal scape small, longer than wide (length 0.10–0.11 mm), pedicel nearly 3 times longer than scape (0.27–0.29 mm) bearing rows of rhinaria; flagellum long and setose. Thorax. Pronotum shorter than vertex (length at midline 0.18–0.19 mm); lateral carinae of pronotum diverging, not reaching posterior margin; posterior margin straight (weakly notched medially). Mesonotum at midline more than 2x length of pronotum (0.47–0.57 mm); lateral carinae weakly diverging, reaching posterior margin, median carina becoming obsolete on scutellum. Wings macropterous (Fig. 1C), exceeding abdomen (forewing 3.07–3.08 mm); forewing venation with fork of RP at approximately same level as fork of CuA (inner and outer subapical cells subequal), fusion of anal veins (i.e., Pcu and A1) much forks of RP and CuA; Sc and RA unbranched, RP 3 branched, M unbranched, CuA 2 branched. Metatibial spur large (Fig. 1D, 0.31 mm), tectiform and smooth, bearing 24–32 fine, black-tipped teeth on trailing edge. Basitarsus with 7 apical spinules, arranged 5+2, second tarsomere with row of 4 spinules. Abdomen. Male terminalia (Figs 2, 4). Pygofer in lateral view (Figs 2B, 4A) roughly quadrate, narrower dorsally than ventrally; anterior and caudal margin truncate, caudal margin without teeth or processes. In caudal view (Fig. 2A), pygofer opening with smoothly rounded margins; diaphragm developed but not strongly sclerotized; opening for gonostyli small, approximately oval; armature projection parallel sided, rectangular and weekly scoop-shaped. Aedeagus (Figs 2B, 4B) tubular, gradually tapering distally, curved ventrally at midlength, with an acuminate process dorsally originating just past apex of curve; gonopore appearing apical. Subtending the aedeagus is a conspicuous process, ~2/3 length of aedeagus; sinuate, widest at base narrowed to an acuminate apex. Gonostyli weakly flattened and rather parallel sided (Fig. 4C); basal angles small, diverging basally, parallel near midlength and abruptly converging near apex to broad apices, weakly convex in caudal view; in lateral view (Figs 2B, 4A) apices appearing hooked ventrally. Anal segment small, rather truncate in lateral view, processes absent, dorsocaudal angle (in lateral view) not projecting); anal column nearly as elongate as height of anal segment.
Remarks. Caldwell & Martorell (1951) remarked that all the specimens of this species were collected at above 2000’ elevation. Few specimens of this species are reported and none of these with host plant associations.
