Kalopona insigna sp. nov.

( Figs 1–13 , 25, 26 )

Diagnosis. Pygofer (Fig. 7) with posterodorsal margin produced as acute process with apex upturned. Aedeagus (Figs 11, 12) with pair of processes arising from shaft base, apex divided in two acute rami: one long directed anterad and one short and dorsal.

Description. (male) length 7.1–7.4 mm. Head ( Fig. 1 ), in dorsal view, strongly produced, median length of crown almost as long as interocular width; anterior margin of crown rounded, longer in the middle than near the eyes; crown smooth; transocular width of head nine-tenths of humeral width of pronotum. Ocelli, equidistant between median line and eyes and between anterior and posterior margin of crown. Head (Fig. 2), in frontal view, with face wider than long; clypeus 1.6 times longer than wide, lateral margins slightly convergent apically, apex rounded; maxillary plates very narrow, not produced ventrally as far as clypeus apex; gena with ventrolateral margins slightly excavated; frons approximately 1.5 times longer than wide, concave below anterior margin of crown; frontogenal suture distant from eye margins by short distance, approximately equal to the scape diameter and reaching antennal ledges, antennal ledge carinated and contiguous with anterior margin of crown. Head (Fig. 3), in lateral view, with crown-face transition foliaceous, with two narrowly separated carinae; frons flat. Pronotum ( Fig. 1 ), in dorsal view, with inconspicuous transverse striae on disc and posterior third, almost smooth; anterior margin straight in the middle portion and rounded laterally; lateral margins convergent anterad; posterior margin almost rectilinear; in lateral view (Fig. 3), rounded and moderately declivous; head and pronotum in continuous slope. Mesonotum ( Fig. 1 ), in dorsal view, wider than long. Forewing (Fig. 4) without extra crossveins; venation indistinct; appendix strongly reduced. Foreleg with profemur, in frontal view, about five times longer than high; AV and PV rows formed by two setae; protibia in cross-section, triangular-shaped, dorsal surface concave; AV row formed by long setae, all of approximately same length and thickness; PD row with ten long setae; PV row formed by very short setae, slightly longer near apex. Hind leg with femoral setal formula 2:2:1; metatibia AD row with intercalary setae between macrosetae; PV row with setae of apical half long and thin, homogeneous in length and thickness; first tarsomere with external row with very short setae and median row absent; apex with four platellae; second tarsomere apex with two apical platellae.

Coloration. Background ( Figs 25, 26 ) uniform yellow, without maculae.

Male terminalia. Sternite VIII (Fig. 5) 1.6 times wider than long; posterolateral corners rounded; posterior margin with middle portion produced and rounded. Valve (Fig. 6) very wide, about three times wider than long; integument thickened only on anterior margin; posterior margin straight. Pygofer (Fig. 7) about 1.7 times longer than maximum height; macrosetae dispersed on posterodorsal quadrant; dorsal margin rounded, with short basal process; posteroventral margin with broadly rounded lobe; posterodorsal margin produced as acute process with apex upturned. Subgenital plate (Figs 7, 8) long, in lateral view, produced posteriorly as far as pygofer apex; in ventral view, wide, approximately 3.3 times longer than wide; maximum width at mid-portion; internal margin rounded; external margin rounded, with microsetae near apex; apex rounded. Connective (Fig. 9) T-shaped, wider than long; rami long and broad; stalk short and wider apically. Style (Fig. 9), in dorsal view, sigmoid near base; outer lobe rounded, in lateral view (Fig. 10), blade strongly curved dorsally on base, U-shaped, and directed posterad near mid-length, ventral margin not serrated, apex axe-like with two tips, one ventral and one dorsal. Aedeagus (Figs 11, 12) with preatrium developed; dorsal apodeme developed dorsally; atrium without processes; a pair of processes arising from shaft base, as long as shaft length; apex divided in two acute rami: one long directed anterad and one short and dorsal; shaft curved dorsally, flattened laterally; apex, in lateral view, with short and flattened spine-like process. Female unknown.

Etymology. The species epithet, insigna , is based on the Latin word " insignis " and means conspicuous. This refers to the pygofer with posterodorsal margin produced as a conspicuous process.

Material examined. Holotype male: " Brasil, AM, Manaus\ ZF-2 Arm.[armadilha] Luminosa\ 06- 08.VII.2011 \ J. Câmara & C. Floriano", DZUP; Paratypes: 16, " Brasil, Amazonas State,\ Barcelos, Rio Padauari, Com.\ Ararão/Ararinha, 00.50487N \ 064.05831W 04-08/VI/2010 \ Luz\ Rafael; Takiya; Cavichioli", DZUP; 16, " Brasil, Amazonas, Barcelos, Rio\ Aracá, Com.

Remarks. K. insigna sp. nov. is similar to K. bilobata , K. distincta and K. trilobata by the shape of style, curved near base and with axe-like apex and more similar to K. distincta by the shape of pygofer with posterodorsal margin produced as acute process. However, it can be distinguished by the pygofer (Fig. 7) with longer acute process on posterodorsal margin and the aedeagus (Fig. 11) with pair of processes arising from shaft base with apex divided in two acute rami.
