Psilephydra cyanoprosopa Hendel
Psilephydra cyanoprosopa Hendel, 1914:100.—Cogan and Wirth, 1977:338 [catalog of Oriental species].
Psilephydra cyanocephala [sic] Cresson, 1934:211 [misspelling of specific epithet].
DIAGNOSTIC DESCRIPTION.—Resembling P. fluvialis but differing from it as follows: length 2.47 to 3.15 mm.
Head (Figures 73, 74, 79, 80): Frons generally dull, tomentose, brownish, mesofrons with some metallic reflections, greenish blue; fronto-orbital bristles posterolateroclinate, weakly developed, 1–2; arista mostly bare, microsetulae sparse and restricted to basal one-third; face shallowly and evenly protrudent, subshiny to shiny, mostly silvery but with considerable greenish blue reflections; facial setae uniformly small, including those along oral margin, moderately densely distributed, lacking series extending from dorsal facial prominence to posteroventral angle of face; genal bristle lacking.
Thorax (Figures 75, 88): Anterior scutellar bristle slightly longer than one-half length of posterior pair; humeral callus bare of setulae; anterior notopleural bristle weakly developed as compared to posterior one; posterior notopleural bristle inserted at about same level as anterior bristle; sternopleural bristle weakly developed as compared with mesopleural bristle; forefemur with row of short, spinelike setae along posteroventral surface; apicolateral setae of fourth tarsomere of foreleg as on other tarsomere; wing (Figure 88); costal vein ratio 4.72; vein M ratio 1.92.
Abdomen (Figures 76–78): Male terminalia as in Figures 76–78.
TYPE-LOCALITY.—TAIWAN. Hoozan.
PRIMARY TYPE MATERIAL.—Lectotype male, here designated, is labeled “Hoozan Formosa H. Sauter, 1911/7. I. [“7” handwritten = (?) 7 Jan]/Psilephydra cyanoprosopa H. det. Hendel [species name handwritten]/Coll. Hendel/LECTOTYPE Psilephydra cyanoprosopa Hendel by W. N. Mathis [red, handwritten].” The lectotype is pinned directly, is in fair condition (some setae missing: dirty), and is in the Naturhistorisches Museum, Vienna. Hendel's original description mentioned 12 syntypes. Of these I have examined the lectotype, a second male (NMW), and a female (ANSP) (here designated as paralectotypes). The remaining nine specimens are presumably in Vienna, although this has not been confirmed.
GEOGRAPHIC DISTRIBUTION.—TAIWAN.
