Neoidiotypa alamagna sp. nov.

( Figs. 1–18 , 106 )

Comments and diagnosis. Neoidiotypa alamagna is certainly the most distinct species within the genus. In other species, the setae on the head and thorax are reduced, whereas in N. alamagna they are strong and long. Neoidiotypa alamagna is similar to N. nigra in the general coloration, black, but it differs from it and from all others species of Neoidiotypa in having the wing longer than the body, absence of spurious vein, long orbital and ocellar setae (weak and short in the female), katepisternal seta present and strong, and abdomen slightly petiolate, base of syntergite 1+2 only slightly narrower than apex. Furthermore, males of N. alamagna have thick, short, spine-like posteroventral setae on the hind femur arising from a cuticular projection, differing from the conditions found in other known species of Neoidiotypa ; and females have cercus with apical seta very reduced and pointed, not modified and flattened.

Description. Holotype male: Measurements (in mm): body length 11.7; head 1.6; abdomen 6.0; wing 13.0. Head ( Figs. 3–5 ): Black, except lunule, slightly paler in color; covered with thin whitish pollinosity ( Figs. 3 ). Setae and setulae black. Head width-height ratio 1.3. Frons-head ratio 0.4. Frons width-height ratio1.35. Ocellidistance ratio 3 ( Fig. 106 ). Ocellar triangle elongate and black, almost indistinguishable from color of frons ( Fig. 4 ), extended posteriorly beyond posterior ocelli until vertex. Antenna black ( Fig. 5 ). Scape elongate, slightly longer than pedicel ( Fig. 5 ). First flagellomere 3.0 times longer than wide. Arista bare. Ocellar seta long and strong, as long as orbital seta ( Fig. 5 ). Postocellar seta absent. Genal seta present and black. Postgenal seta present, weaker than genal seta. Palpus dark brown; linear, apex as wide as base ( Fig. 5 ). Prementum black ( Fig. 5 ). Thorax: Scutum 1.3 times longer than wide. General color black ( Figs. 1, 2 ), covered with thin and silvery pollinosity. Setae black. Postpronotal seta absent. Postsutural supra-alar seta as long as, but distinctly thinner than, postalar seta; intra-alar seta as long and thin as postsutural supra-alar seta. Postsutural dorsocentral seta long, distinctly longer and more robust than setulae around it. Presutural supra-alar and proepimeral setae present and slightly robust. Katepisternal seta almost as robust as anepisternal seta. Halter yellowish. Legs: Mid femur slightly more swollen than fore and hind femora; fore tarsomeres as thick as mid and hind tarsomeres. Spine-like setae black. Fore leg dark brown, except trochanter pale brown. Mid and hind coxae, femora and tarsomeres 4–5 brown. Mid and hind trochanters and tibiae pale brown. Tarsomeres 1–3 yellow. Pulvilli yellowish. Fore femur with spine-like antero- and posteroventral setae on apical third; spine-like posteroventral setae stronger and more numerous than anteroventral setae. Mid coxa with two long medial setae. Mid femur with spine-like antero- and posteroventral setae on apical fourth; spine-like posteroventral setae stout, short and arising from cuticular projection ( Figs. 6, 7 ), evenly spaced between one another; ventral surface with hollow on apical third. Hind femur with spine-like antero- and posteroventral setae on apical half; dorsal seta absent. Wing: Longer than body length ( Fig. 1 ); dark brown on anterior half and pale brown on posterior half ( Fig. 1 ); spurious vein absent ( Fig. 1 ). Abdomen ( Figs. 1, 8 ): Black, densely covered with black setulae, except syntergite 1+2, bare on median third. Syntergite 1+2 2.3 times longer than tergite 3; base slightly narrower than apex; median portion narrower than apex ( Fig. 8 ); with preapical and apical set of ten strong setae on laterodorsal surface ( Fig. 8 ). Tergites 3–5 similar in length; as wide as apex of syntergite 1+2. Tergites 3–4 with row of preapical and apical long setae on laterodorsal surface ( Fig. 8 ). Sternites 2–5 dark brown covered with dark brown setae. Male terminalia ( Figs. 9–11 ): Epandrium slightly wider than high; densely covered with long setae ( Fig. 9 ). Cerci developed and very sclerotized, densely ciliated; basal and median region with setae of similar lengths, shorter than preapical and apical setae; one apical seta distinctly longer ( Fig. 9 ). Lateral surstylus without medial projection ( Fig. 9 ); slightly ciliated. Medial surstylus with two apical setae, close to prensiseta ( Fig. 10 ); anterior preapical region acuminate ( Fig. 10 ). Prensiseta very developed and curved, with apex almost acuminate ( Fig. 10 ). Distiphallus sparsely ciliated throughout its length; apex with two sclerotized plates ( Fig. 11 ).

Paratype female ( Figs. 12–18 ): Similar to male, except: Measurements (in mm; N=1): body length 11.7; head 1.8; abdomen 5.9; wing 12.0. Head ( Figs. 14, 15 ): Setulae on frons whitish. Ocellar triangle black, indistinguishable from color of frons ( Fig. 15 ). Ocellar seta very thin and short, distinctly smaller than orbital seta ( Fig. 15 ). Postgenal seta as long and strong as genal seta. Thorax: Postpronotal seta present. Legs: Mid femur as thick as fore and hind femora. Legs brown, except mid basitarsus pale brown. Fore femur with spine-like posteroventral setae as thick and numerous as spine-like anteroventral setae. Mid femur with spine-like posteroventral setae normal, similar to spine-like anteroventral setae. Hind femur with spine-like antero- and posteroventral setae on apical third. Abdomen ( Figs. 16, 17 ): Setulae on syntergite 1+2 whitish. Female terminalia ( Figs. 17, 18 ): Not dissected, observed only externally: Oviscape dark brown, densely covered with whitish setulae ( Fig. 17 ). Cerci 0.21 mm long; tip round and large, 0.14 mm in width ( Fig. 18 ). Apical seta very reduced, pointed, not flattened. Basal dorsal and ventral setae long, dorsal seta longer than ventral.

Type material. Holotype male, INBio: “ COSTA RICA. Prov. [Province] Heredia, P [Park]. N [National]\ Braulio Carrillo, Transecto\ altitudinal Barva – La Selva,\ 2300m 17 ABR [April] 2002, M Zumbado [collector],\ Libre, L_N_240000_524300 #83422 {10.403; -84.0082}” “INB0003945533\ INBIOCRI COSTA RICA ”. The holotype is in excellent condition; the abdomen was detached beyond tergite 3, cleared and placed in glycerine in a micro-vial attached to the pin of the specimen.

Paratype: Costa Rica: Puntarenas Province: R.I. Ujarrás-Salitre-Cabagra, from Tararia to Cerro Nai, 3129m, L_S_353000_564700 #68051, Libre, 17.iv.2002, M. Alfaro col. INB0003460636 (1♀, INBio).

Distribution. Costa Rica.

Etymology. The specific epithet is a noun that refers to the long wing, which is longer than the length of the body (from Latin, ala = wing; magna = large).
