Sarcofahrtiopsis piscosa
The species described here possesses all the autapomorphic features of the genus Sarcofahrtiopsis Hall, 1930. It differs from all other species of Sarcofahrtiopsis in the curved surstylus and in structural details of the phallus. The vesical extension is tubular only at the base and not sagittally bifurcated, and it soon flattens into an elongated plate that is bent proximally, and is horizontally forked or bilobed at the tip. Distal to the vesical
extension is a single, median row of den.ticles, of which the distalmost is larger than the others and shaped like a small, spiny, recurved process

Male. Length = 5 mm (n = 4). Head. Fronto-orbital and parafacial plates covered with lightly golden microtomentum; parafacial plate with single row of setulae along inner eye margin; frontal vitta well defined, dark, with row of 4–5 frontal setae along its external margin, reaching the midpoint of the second antennal segment, inner and outer vertical setae developed, ocellar setae similar to frontals, one pair of postocellars, two proclinate and one reclinate fronto-orbital setae. Antenna black, first flagellomere with gray microtomentum; arista long plumose on basal 1/2. Thorax. With the usual three longitudinal stripes. Chaetotaxy: Acrosticals 0+1, dorsocentrals 2(-3)+3, intra-alars 1(-2)+2, supra-alars 1(-2)+3, postalars 2,
postpronotals 2, notopleurals 2 (subprimaries absent), katepisternals 3 (middle one weaker, placed at equal distance and at same level from the others), meropleurals 5, postalar wall bare, scutellum with one preapical, 0 apical, two strong and one weak laterals. Wings: hyaline, tegula small and black, R1 and R4+5 both setulose in almost their entire length. Costal spine absent. Legs: anterior femur with a row of setae on
posterodorsal and posteroventral margin; anterior tibia with one posteroventral seta; mid femur with two anterior, one posteroventral and one anteroventral setae, no ctenidium distally on posteroventral margin; mid tibia with one posteroventral and one anteroventral setae; hind femur with one anteroventral and one anterodorsal row of setae; hind tibia with one anterior, one posterodorsal, one posterior and one
posteroventral seta. Abdomen. Brown or red-brown with a dark median stripe and elongate or triangular
lateral spots on T3–4, small spots posteriorly on T5; silver-grey or partly faintly golden microtomentum. T4 with one pair of median marginal setae and two pairs of lateral marginals. T5 with row of about 12 marginals. Sternites quadrangular with rounded posterior corners, covered randomly distributed fine, hair-like setae, darker and stronger setae on posterior margin; fifth sternite subtrapezoidal, posterior margin slightly convex with no median cleft.
Terminalia. Syntergosternite 7+8, epandrium and cercus dark brown with numerous setae, syntergosternite 7+8 with a row of long, marginal setae, epandrium with stronger setae on dorsal surface; cercus almost straight, pointed at tip with longer setae towards base, shorter ones distally; surstylus broad, curved boomerang-like, densely covered with microtrichiae on base, with long setae on distal margin; gonopod short and as long as the paramere, with long setae along the posterior margin; paramere slender, slightly curved, with a long median seta proximally on anterior margin; parameral apodeme slender and elongate. Phallus well sclerotized with a weakly demarcated division between basi- and distiphallus, and a small juxta; lateral and median styli small and apically positioned, lateral styli very simple and unadorned, median stylus with a rounded base and a little rugosity at apex; vesica large with a flattened proximal projection and a spiny ventral margin.
