Neoidiotypa sticta sp. nov.

( Figs. 81–105 , 111 )

Comments and diagnosis. Similar to N. flaviatra and N. mexicana , N. sticta has the postpronotal lobe yellow, the scutum black with two parallel yellow stripes, and the abdomen with yellow basal bands on tergites 3–5. It differs from these species by the presence of two opposite spurious veins on vein R2+3. The wing with two spurious veins is very similar to the wing of N. appendiculata , however, N. sticta differs from this species in the color of the scutum, which is black, and in the presence of golden yellow stripes, black setae on the head and thorax, the ocelli-distance ratio 1.5 and the yellow coxae. Furthermore, N. sticta is the only species in which the female generally has portions of the pleuron, (for instance, anepimeron and/or meron, and/or postmetacoxal bridge areas) with small brown spots; these are absent in the male.

Noto-, meso-and metapleura yellow, except: anteromedian brown band on anepisternum; posterior part of anepimeron and dorsomedian part of meron with small brown spots, similar to spots of a cheetah ( Fig. 86 ); and anatergite dark brown. Subscutellum and mediotergite dark brown. Setae black. Postpronotal seta developed, distinctly longer and thicker than setulae around it. Postsutural supra-alar, postalar, intra-alar and postsutural dorsocentral setae developed, similar in length and thickness, except postalar seta slightly thicker. Presutural supra-alar and katepisternal setae absent. Proepimeral seta very weak. Halter yellowish.

Pulvilli yellowish. Fore femur on apical half with small, spine-like setae on antero- and posteroventral surfaces; spine-like setae similar in number and thickness. Mid coxa with one long black medial seta. Mid femur with spine-like antero- and posteroventral setae on apical half; spine-like posterodorsal setae without modifications, evenly spaced; ventral surface without hollow. Hind femur with spine-like antero- and posteroventral setae on sub-base; two preapical dorsal setae. Wing: Shorter than body length ( Fig. 82 ); brown on anterior half and yellowish on posterior half; two opposites spurious veins on vein R2+3 ( Fig. 96 , photo of paratype). Abdomen: Syntergite 1+2 on basal and apical third, and tergite 3 on apical two-thirds pale brown; syntergite 1+2 on median third and tergite 3 on basal third, yellow; tergite 4 on basal third yellow and on apical two-thirds brown; tergites 5–6 brown; covered with black setulae, except some yellow setulae on lateral margin on syntergite 1+2 and tergite 3. Syntergite 1+2 2.0 times longer than tergite 3; basal three-fourths distinctly narrower than apical fourth; with seven preapical and apical yellow setae arranged randomly on laterodorsal and dorsal surfaces. Tergites 3–4 similar in length, tergite 5 slightly shorter. Tergite 3 gradually wider than apex of syntergite 1+2. Tergites 4–5 gradually narrower than tergite 3; with row of apical black setae on laterodorsal and dorsal surfaces. Sternites 2–6 ( Figs. 91–95 , drawing from paratype) yellowish covered with yellow setae and setulae, except some apical black setae on sternites 3–6. Female terminalia (observed through paratype, Figs. 87‒90 ): Oviscape pale brown, 1.35 mm long ( Fig. 87 ). Taenia brown, long, two-thirds as long as oviscape; almost as sclerotized as oviscape ( Fig. 87 ). Eversible membrane pale brown ( Fig. 87 ).

Basal dorsal and ventral setae slightly long, dorsal seta longer than ventral. Two semispherical spermathecae ( Fig. 88 ).

Variation. Some paratypes females may have the meron on median third, and the katepisternum on anterior and ventral regions brown, and the band on anepisternum may be absent. The paratype deposited in USNM does not have the spots on pleuron similar to spots of cheetah, but those spots are brown marks, on the same regions as the holotype. Females also may have the yellow stripes on tergites 3–5 less or more conspicuous than those in the holotype.

Paratype male ( Figs. 96‒105 ): Similar to female, except: Measurements (in mm; N=1): body length 12.4; head 1.6; abdomen 6.5; wing 10.5. Head ( Figs. 98‒100 ): Brown, without spots; frons and parafacial on eye contour and vertex densely covered with golden pollinosity. Head width -height ratio 1.4. Frons-head ratio 0.4.

Frons width-height ratio 1.3. Scape and pedicel pale brown. Thorax ( Figs. 96, 97 ): Brown spots on pleuron not resembling cheetah spots pattern, present on same regions as holotype. Legs: Spine-like setae on femora orange and black. Male terminalia ( Figs. 101–105 ): Epandrium wider than high; densely covered with setae and setulae ( Fig. 102 ). Cerci developed ( Figs. 101, 102 ) and slightly sclerotized; densely ciliated, especially at base ( Fig. 101 ); basal half with setae shorter than apical and preapical setae; one apical seta distinctly longer ( Figs. 101, 102 ). Lateral surstylus with medial rounded projection; densely ciliated ( Figs. 101, 102 ). Medial surstylus with set of preapical and apical setae, close to prensista ( Fig. 105 ); anterior preapical region rounded and convex ( Fig. 105 ). Prensiseta developed, elongated and curved, with apex slightly acuminated ( Fig. 105 ). Distiphallus slightly ciliated on basal fourth ( Fig. 96 ) and densely ciliated on apical two-fourths ( Figs. 103, 104 ); apex membranous with one small weakly sclerotized plate.
