(Figs. 19 –44, 107)
Neoidiotypa appendiculata (Loew 1873): 183 (pl. 9, fig. 6: wing) (Idiotypa); Lectotype male, paralectotype female, MCZ. Type-locality: Cuba. Refs.: Osten-Sacken 1878: 187 (catalogue); Aldrich 1905: 598 (catalogue); Coquillett 1910: 555, 575 (citation); Hendel 1911a: 389 (note); Hendel 1911b: 40 (citation; plate 3, figs. 60‒63: head, abdomen, wing); Curran 1934; 1965: 282 (fig. 78: head), 283 (fig. 96: wing); Aczél 1950: 40 (catalogue); Steyskal 1968:6 (catalogue); Hancock 2010: 878 (citation).
Comments and diagnosis. The coloration of the scutum of N. appendiculata is peculiar: the scutum has yellowish orange and dark brown marks, differentiating it from the others; although the patterns of bands and stripes on the scutum of this species and N. flaviatra, N. mexicana and N. sticta are similar. Identical to N. sticta, the wing of N.
appendiculata has two opposite spurious veins on vein R2+3, but it differs from that species by having rust brown setae on the head and thorax, coxae dark brown, mid and hind femora with large dark brown or brown marks, and the females have syntergite 1+2 with basal dark brown mark, distinctly darker than the remainder of abdomen.

Wing: Slightly shorter than body length (Fig. 19); pale brown on anterior half and subhyaline on posterior half (Fig. 19); two opposite spurious veins on R2+3 (Fig. 32, photo of paralectotype). Left wing with sinuosity on costal vein where it meets vein R1 (Fig. 19). (It seems to be a deformation in the specimen, since the other wing and the other specimen do not have this aberration). Abdomen (Figs. 19, 20, 28): Rust brown, except syntergite 1+2 rust yellow on median third (Figs. 20, 28), tergites 3–4 with narrow whitish pollinose stripe basally (Figs. 19, 28); covered with yellowish setulae.

Neoidiotypa appendiculata (Loew), paralectotype female: 33–34. Habitus: 33. Dorsal view; 34. Lateral view; 35–38. Head: 35. Frontal view; 36. Dorsal view; 37. Lunule in detail; 38. Lateral view; 39–40. Wing: 39. General view; 40. Ve i n A 1CuA 2 in detail; 41. Thorax, dorsal view; 42. Abdome, dorsal view (black arrow indicates the dark brown mark at base of syntergite 1+2); 43. Oviscape; 44. Cerci in detail (small red mark indicates the tip of cerci width). Scales lines: 1.0 mm; except fig. 37: 0.5 mm.
preapical region rounded and convex (Fig. 29; remarks: the medial surstylus was displaced anteriorly, and it is visible only in anterior view. This displacement frequently happens when the male terminalia are dissected, which makes the examination of the medial surstylus and the general shape of the terminalia difficult). Prensiseta developed and slightly curved, with acuminate apex (Fig. 30). Distiphallus slightly ciliated on basal third (Fig. 31) and densely ciliated on apical two-thirds (Figs. 31, 32); apex membranous with one weakly sclerotized plate (Fig. 31).
Paralectotype female (by present designation) (Figs. 33–44): similar to male, except: Measurement (in mm; N=1): body length 10.2; head 1.4; abdomen 5.0; wing 8.1. Head: Head width-height ratio 1.54 (Fig. 35). Frons width-height ratio 1.15 (Fig. 35). General color yellowish, except: frons with two dark brown bands on ocellar triangle and above lunule (Figs. 35–37); face with two lateral dark brown spots (Figs. 35, 36); occiput with black stripe on upper region (Fig. 36). Thorax (Figs. 33, 34, 41): Stripes and bands similar to male, except large median rust brown stripe on anterior two-thirds; and the following different marks on scutum: lateral to dorsocentral stripe presutural area dark brown, and postsutural area from transverse suture to base of scutellum rust brown (Fig. 34). Abdomen (Fig. 42): Rust orange, except syntergite 1+2 dark brown at base (Fig. 42, region indicated by black arrow) and yellow on median portion. Syntergite 1+2 2.3 times longer than tergite 3. Female terminalia (Figs. 43, 44): Not dissected, observed only externally: Oviscape rust yellow (Fig. 43). Cerci 0.3 mm long; tip straight and slightly large, 0.1 mm in width, 1.5 times length of apical seta (Fig. 44). Basal dorsal and ventral setae slightly long, dorsal seta longer than ventral.
Type material. Lectotype male, by present designation, MCZ (Figs. 19‒28): “288” [small grey label], “Loew\coll.”, “ appendiculata \m.” [handwritten], “ Type \13280” [red label] (Fig. 20); “ Lectotype ” [red] label was added. The lectotype is relatively well preserved (Figs. 19, 20), except for the dirt on body; the abdomen was detached beyond tergite 3, cleared and placed in glycerine in a micro-vial attached to the pin of the specimen.
Paralectotype female, by present designation, MCZ (Figs. 33‒44): “250” [small grey label], “Loew\coll.”, “ Type \13280” [red label], “ N. appendiculata \ *Loew\ Monogr.III.” [handwritten], “ Lectotype ” [red] label was added. Loew (1873, pg. 184) stated in the original description that he examined two males and one female collected in Cuba, however, we found and examined only one male. Hendel (1911a, pg. 389) examined another specimen male from Cuba deposited in the Naturhistorisches Museum Wien, Austria (NMW), but we were not able to examine this specimen. Although in the label there is no indication about the locality, Loew (1873, pg. 186) stated that the material was collected in Cuba. Loew published three monographs in sequence (1862, 1864 and 1873), which he wrote based on material donated by Osten-Sacken. In the winter of 1857‒1858, Osten-Sacken travelled to Cuba and stayed there during five weeks (Osten-Sacken, 1903, pg. 7). As part of an autobiographical account, Osten-Sacken listed the colors of the specimens’ labels and their meanings. The small grey label indicates specimens that were collected in Cuba, described originally as “silver squares mean Cuba (Loew Collection)” (Osten-Sacken, 1903, pg. 94).
Additional material: Dominican Republic, Hato Mayor, Park los Haitises, 3km W, Cueva de Arena, 19º04’N 69º29’W, 20m, 7–9.vii.1992, Mesic lowland forest, R. Davidson, J. Rawlins, S. Thompson, C. Young colls. (1 ♀, USNM).
Comments. The specimen female from Dominican Republic has some differences from the types: the preservation of the specimen is considerable better; the color is more vivid, differently from pale color of the paralectotype. However, the spots on frons, color and marks on thorax (except lateral marks on scutum slightly more elongate, and katepisternum brown with small dorsal part yellow) is identical to paralectotype. The abdomen is brownish golden with contrasting yellow bands at base of tergites, but the dark brown mark at base of syntergite 1+2 is also present. The ocelli-distance ratio is 1.25, slightly larger than in the types, and the spine-like setae on legs are dark brown. The right wing has only one spurious vein on vein R2+3 directed into cell r1, but the left wing has the two opposite spurious veins on R2+3, as well as in the types.
Distribution. Cuba, Dominican Republic (new record).
