Abdomen (Fig. 17). Tergites and sternites I–III brown, golden tomentose; tergites and sternites IV–VIII black, sparse golden tomentose, brown apically; tergites II–IV with marginal setae; sternite VIII developed, fused only basally, inner margin angular with long, yellow setae (Fig. 24). Terminalia. Black (Fig. 17); epandrium with dorsal, subapical, internal acute projection (Fig. 18) and with a group of long golden setae apically (Figs. 18, 20, 22); gonocoxite triangular apically (Fig. 25); gonostylus rounded apically (Fig. 25); hypandrium with two ventral projections and ‘U’-shaped medio-apically (Fig. 21); ejaculatory apodeme wide and long proximally, in lateral view (Fig. 23); aedeagus with three thin and short tubes; subepandrial sclerite with a protuberance medially. Lengths: Body 12.2 mm; wing 8.2 mm. Holotype condition. Right antennal style, supraalar, and postalar and left apical scutellar macrosetae lost; right mid leg lost. Detached wing mounted on microslide in Canada balsam. Part of the abdomen and terminalia placed in microvial with glycerin. Variation. Body: 11.3–13.2 mm; wing 8.0– 8.9 mm; mystax with one to eight black macrosetae, remaining yellow; one to two postalar black macrosetae; five to six black and one yellow dorsocentral macrosetae; fore femur basal 2/3 black and apical 1/3 brown; mid and hind femur mostly black, except for base and apex brown; mid and hind tibiae basal 4/5 brown and apical 1/5 black; middle femur with two yellow macrosetae; posterior femur with two yellow and one black anterior macroseta, two yellow and one black anteroventral macroseta; tergites and sternites black with brown apex. Female. (Figs. 26–28): Similar to male except for following: body length (13.6–15.5 mm), wing (8.2–9.3 mm); mystax black in dorsal half and yellow on ventral half; one to two yellow postalar macrosetae; fore femur light brown anteriorly and with a dark brown stripe medially; mid femur basal 1/5 light brown anteriorly and dark brown to black on apical 4/5; hind femur basal 1/3 light brown anteriorly and dark brown to black on apical 2/3; fore tibia brown; mid and hind tibiae basal 4/5 brown and apical 1/5 black; mid femur with two yellow and one black macrosetae anteriorly, and three yellow and one black macrosetae anteroventrally; hind femur with three yellow and one black anteroventral macrosetae; fore tibia with two black macrosetae posteriorly; mid tibia with three yellow macrosetae posteriorly; tergites and sternites I–VII brown, golden tomentose; tergite and sternite VIII dark shining brown; ovipositor long (Figs. 10, 12); sternite VIII twice the length of sternite VII (Figs. 26, 28); median sclerite at posterior end of furca (remnant of tergite IX) absent; genital fork long with narrow arms; three oval sclerotized capsules of spermathecae (Fig. 27). Etymology. From the Latin aurata = gold, referring to the group of long and golden apical setae on epandrium (Figs. 18, 20, 22). Distribution. Guanacaste province, Costa Rica (Fig. 41). Comments. The female of Martintella aurata sp. nov. can be distinguished from Martintella fernandoi sp. nov. mainly by the size of tergite and sternite VIII. In Martintella aurata sp. nov. sternite VIII is long, twice the length of sternite VII (Figs. 26), while in M. fernandoi sp. nov. sternite VIII is less than twice the length of sternite VII (Fig. 39).
