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).
