description: Kalopona sagytta sp. nov.
(Figs 13 –24, 27, 28)
Diagnosis. Pygofer (Fig. 19) with long spine-like basal process on dorsal margin. Style (Fig. 22) with ventral margin serrated apically, apex enlarged and truncated. Aedeagus (Fig. 24) with apex, in posterior view, arrowshaped, with two short subapical lateral spines..
Description. (male) length 8.4–8.5 mm. Forewing (Fig. 16) with venation distinct. Other characteristics as in the previous description.
Coloration. Background (Figs 27, 28) uniform yellow, without maculae.
Male terminalia. Sternite VIII (Fig. 17) 2.7 times wider than long; posterior margin almost straight, with two shallow notches on each side of middle. Valve (Fig. 18) very wide, 3.3 times wider than long; integument thickening present on anterior and posterior margins; posterior margin curved laterally and straight in middle. Pygofer (Fig. 19) about 1.3 times longer than maximum height; macrosetae dispersed near dorsal margin; dorsal margin rounded, with long spine-like basal process, with approximately half length of pygofer, directed posterad; posteroventral margin rounded forming a small and membranous lobe with short setae apically; posterodorsal margin with a small projection acute directed dorsally. Subgenital plate (Figs 19, 20) very long, in lateral view, produced posteriorly beyond pygofer apex; in ventral view, wide, approximately 2.7 times longer than wide; abruptly enlarged near base; lateral margins approximately parallel; internal margin rounded; external margin straight, with microsetae near apex; apical portion emarginated near apex; apex rounded. Connective (Fig. 21) Tshaped, wider than long; rami long and broad; stalk short and wider apically. Style (Fig. 21), in dorsal view, sigmoid near base; outer lobe rounded, in lateral view (Fig. 22), blade curved on base, U-shaped, and directed posterad near mid-length of blade, ventral margin serrated apically, apex enlarged, truncated and with one dorsal small spine-like process. Aedeagus (Figs 23, 24) with preatrium developed; dorsal apodeme developed laterodorsally; a pair of processes arising from shaft base, very narrow, not extending as far as aedeagus apex; shaft curved dorsally; apex, in lateral view, with a rounded and flattened process on anterior margin and two very small and flattened process on posterior margin, in posterior view, arrow-shaped, with two short lateral subapical spines. Female unknown.
Etymology. The species epithet, sagytta, come from the Latin word " sagitta " and means arrow. This refers to the shape of the aedeagus apex in posterior view, resembling an arrow head.
Material examined. Holotype male: " Brasil, Mato Grosso \ Sinop\ X/1975 \ M. Alvarenga", DZUP; Paratypes: 16, same data of holotype, DZUP.
Remarks. K. sagytta sp. nov. is similar K. distincta by the shape of pygofer (Fig. 19) with a acute process on dorsoapical margin. K. sagytta sp. nov. can be easily distinguished from the other Kalonona species by the stile (Fig. 22) with apex more enlarged and truncated.
