Maruina ( Maruina) kallyntrona sp. nov.
( Figs. 41–47 View FIGURE 41–47 )
Diagnosis. Combination of the following characters: wing apex long and narrow, with distance from R 5 to R 4 almost 2X the distance from R 4 to R 3; hypandrium expanded medially in a triangular sclerite pointing posteriorly and with sinuous anterior margin; aedeagal sheath with lateral sclerotized areas connected medially; tenaculum distally fimbriated, resembling a hair-brush; female hypogynium with very narrow lobulae.
Description. Male. Head ( Fig. 41 View FIGURE 41–47 ): distance between eyes equivalent to 9 facet diameters, interocular suture present, frons with two patches of setae on lateral gibbosity near antenna insertion; antenna with scape longer than pedicel, 13 flagellomeres, 2–12 with ascoids; palp segment 4 with two apical setae, palpus formula: 1.0:1.3:1.3:2.1. Wing ( Fig. 42 View FIGURE 41–47 ): C with break on anterior margin, at the level of base of R 1, R 2 united to R 4 and R 5, R 3 short, R 5 infuscate ending at wing apex, M 1 united to M 3, M 2 incomplete, Wing length 1,46 mm, maximum width 0,195 mm. Terminalia ( Figs. 43–45 View FIGURE 41–47 ): hypandrium well sclerotized, expanded medially in a triangular sclerite pointing posteriorly and with sinuous anterior margin, resembling a hang-glider, which is continuous with sclerotized aedeagal sheath by a membranous area; gonocoxite with approximately 7–8 setae on dorsal surface, gonostylus simple; aedeagus with anterior long and thin straight spines and a pair of posterior short and thick dagger-like spine; aedeagal sheath with lateral sclerotized areas connected medially by a large distal sclerotized area; ejaculatory apodeme oval; epandrium around 2X wider than long with a single small central aperture, basally with anterolateral arms that extends dorsally until the hypandrium, apical margin concave; subepandrial sclerite V-shaped, anterior portion where arms meet rounded and faint; epiproct largely visible with micropilose caudal digitiform projection medially; hypoproct subquadrate with posterior margin straight; epandrial appendage with a single tenaculum at apex, distally fimbriated, resembling a hair-brush.
Female. Similar to male except: Head: antenna incomplete, palpus formula: 1.0:1.3:1.4:2.5. Wing: length 1,73 mm, maximum width 0,265 mm. Terminalia ( Figs. 46–47 View FIGURE 41–47 ): hypogynial valve with apical lobes narrow and approximately eight true setae inserted apically, internal lateral bristles projecting medially from distinct and small posterolateral lobulae.
Type material. Holotype: ♂ BRAZIL, Roraima, Amajari, Serra Tepequém , 10-12.vi.2010, malaise, col. J. A. Rafael; F. F. Xavier; R. Machado; R. Freitas ( INPA) ; Paratypes: 6 ♀♀, 8 ♂♂ same data .
Etymology. From Greek kallyntron, meaning ‘broom, brush’, in reference to the hairbrush like tenaculum.
Distribution. Brazil ( Roraima).
Holotype condition. Slide mounted, head and wings separated from thorax, antenna complete, terminalia in dorsal view.
Remarks. Among Maruina ( Maruina) species, only M. ( M.) lanceolata , known from British Columbia ( Canada), California ( USA) and Baja California ( Mexico), also has antenna with only 13 flagellomeres. M. ( M.) kallyntrona can be differentiated from M. ( M.) lanceolata by the wing apex, which is conspicuously elongated after R 4 in the first. The long and apically fimbriated tenaculum is also found in M. ( M.) dama Hogue, 1973 , but the two species can be differentiated by the number of flagellomeres ( 14 in M. ( M.) dama ) and morphology of aedeagal spines.
