description: Krameragallia rex (Kramer) comb. nov.
(Figs 1–15; 22)
Agalliopsis rex Kramer, 1960: 63 –65.
Length. Male holotype, 8.80 mm.
Holotype redescription.
Head and thorax (color). Ground color of anterior dorsum black. Face (Figs 2, 22) mostly black; maxillary plates well developed laterally, dark brown and longitudinally striated. Forewings (Figs 1, 2) red, except for distal fourths, which are dark brown. Legs black (Fig. 2). Metathoracic legs: tibial row I with 12 setae, intercalary setae absent; row II with ten primary setae, similar to those of row I, setal bases elevated, intercalary setae present and distinct; row III with 11 setae beginning midway along tibia and becoming progressively larger toward apex; row IV with approximately 45 primary setae.
Male genitalia. Pygofer (Fig. 3), in lateral view, with posterior margin roundish with well developed lobe bearing scattered small setae. Subgenital plates (Fig. 4), in ventral view, fused to valve, not fused to each other; well developed, almost parallel sided to proximal third then broadening for the next third and finally narrowing toward apex; with v-shaped less sclerotized area between valve and plates; in lateral view (Fig. 3) extending posteriorly beyond pygofer apex; surface with scattered setae, dorsoapical setae longer; in dorsal view, median area bearing well sclerotized structure articulated to styles. Style (Fig. 5), in dorsal view, slender, well developed; fork well developed; shaft with elongate lateral subacute process on distal half of outer margin and well developed projection on proximal half of inner margin articulated to subgenital plate; subapical area bearing few long setae; apex truncate. Connective (Fig. 6), in dorsal view, short, Y-shaped, and articulated with aedeagus. Aedeagus (Fig. 7) simple, symmetrical; shaft, in lateral view, long and sinuous, directed anterodorsally on basal portion with ventral process running parallel-sided to shaft and then strongly curved posterodorsally, remaining area gradually curved ventrally and then directed posteriorly; apex (Fig. 8) with pair of lateral elongate processes on each side: shorter one located subapically and longer one apically. Anal tube, in lateral view, with segment X well developed; posteroventral margin bearing pair of anal ring with long processes with apex hook-shaped and directed inward (Figs 9, 10).
Additional material.
Length. Male specimens 7.4–8.9mm; female specimens 8.5–9.0mm.
Females (color). Abdomen mostly red (Fig. 11); pygofer, gonoplacs and base of ovipositor dark-brown. Other color features similar to holotype.
Female genitalia (based on two specimens). Abdominal sternites III to VI rectangular and subequal in length, not reduced or modified. Sternite VII (Fig. 12), in ventral view, large, slightly striated medially; distal margin concave medially with submedial pair of short slightly convex lobes and then by pair of elongate slightly convex lateral lobes; base of ovipositor exposed. First valvulae (Fig. 15), in lateral view, dorsally curved from base; basal area of each valvula bearing well developed semispherical basiventral processes, outer margin with slight median emargination, covered with spiniform processes; ventral interlocking device distinct, located on basiventral portion of shaft; dorsolateral surface with reticulate sculptured area formed by oblique rows of scale-like processes (Fig. 16); ventroapical region with scale-like processes; dorsoapical and ventroapical margins pseudodentate; apex subacute. First valvifer (Figs 13–15), in lateral view, strongly developed, hook-shaped, directed ventrally, bearing numerous denticuli; ventral margin bearing lobe, covered with denticuli. Second valvulae (Fig. 17), in lateral view, slightly curved dorsally from base, with broadest point on apical fourth; dorsal hyaline area present; dorsal prominence pronounced on apical fourth; teeth (Fig. 17) mostly subtriangular, not bearing denticles, positioned on distal half of dorsal margin, mostly uniform in size and shape toward apex; shaft apex subacute. Gonoplacs, in lateral view, with proximal half broadening gradually toward median portion; apex narrowly rounded; surface with tiny spiniform processes.
Intraspecific variation (based on all male and female specimens). Fresh specimens have brighter red and black color pattern. Metathoracic legs with tibial row I setae variable in number from ten to 15; setae may vary in length and thickness. Some specimens have a pair of shallow concavities on the upper area of crown. A male specimen from Colombia differed from males from Ecuador in the following characters: genae brown; pronotum black next to crown, brown medially and pale brown laterally, surface slightly punctured; posterior margin of pygofer truncate rather than rounded; aedeagus slightly smaller; processes of the segment X more elongate.
Material examined. Holotype: male, “ Ecuador \ 3000 ft. (NMNH) No. 64866. Five additional specimens as follows: one male “ ECUADOR: Loja;\ Loja/ Malacatos\ 1900m. 21–22 Aug.1977 \ Luis E. Pena” (MNRJ); one male “ ECUADOR: Napo Prov. \ Hac. Aragon (Sierra\ Azul) 0.67o S. 77.92o W \ 26.iii.–21.iv.1996 \ P. Hibbs. Malaise” (LACM); one male “ Colombia, Caldas\ Mt. Ruiz 4000+m.\ 21 August, 1969\ D.H. Messersmith” (NMNH); one female “ ECUADOR: Pinchincha\ Santo Domingo (79. 6\ km. E.) 2545 m.elev.\ 7 Jan 1978 WNMathis” (NMNH); one female “ ECUADOR: Napo Province\ Oyacachi. 3000m. 0.22o S \ 78.08o W. 15.iv.–16.v. \ 1996. P.Hibbs. Malaise” (MNRJ).
