Diagnosis.

This species is distinguished from other congeners by the following combination of characters: Small to moderately small shore-fly species, body length 1.50-2.05 mm; generally black, subshiny to shiny. Head: Frons mostly brownish black to black, sparsely brownish microtomentose, more so on anterior portion, subshiny, some specimens with 2 gray spots along ventral margin just dorsad of antennal bases. Antenna mostly black, only basal flagellomere with ventrobasal area with some yellowish to yellowish orange coloration. Face mostly shiny black, especially medially and laterally, between with some areas sparsely microtomentose and in antennal grooves, dorsal half; antennal grooves evident, dorsad of dorsoclinate facial pair of setae; ventral half of face slightly receded; bearing 2 larger facial setae, dorsal seta at about midfacial height, dorsomesoclinate; ventral seta just dorsad of epistomal margin, slightly dorsoclinate; parafacial thin, black. Gena relatively short, gena-to-eye ratio 0.06-0.07. Thorax: Mesonotum uniformly sparsely microtomentose, brownish black to black; presutural supra-alar seta lacking or indistinguishable from surrounding setae; pleural region black; dorsal 2/3 of anepisternum finely granulose, subshiny, anteroventral portion smooth, shiny. Wing hyaline, lacking any pattern or markings; costal vein ratio 0.75-0.89; M vein ratio 0.58-0.61. Legs, except tarsi, black; tarsi yellow; apical 1-2 tarsomeres darker, tan to brown; forefemur with sparse row of 4-5, stouter, spine-like setae along apical half of posteroventral surface. Abdomen: Generally black, subshiny to mostly shiny, dorsum of tergites very sparsely and finely microtomentose, faintly whitish gray. Male terminalia (Figs 51-54): Epandrium in posterior view (Fig. 51) almost as wide as high, as an inverted U, dorsal arch very thin, vertical, lateral arms essentially parallel sided, wider than width of cercus, in lateral view (Fig. 52) widest at ventral 1/3, ventral margin step-wise rounded, overall as a robust tear drop with an anterior, short, shallowly pointed projection at widest width; cercus in posterior view (Fig. 51) bar-like, elongate, narrow, parallel sided, not fused with ventral margin of cercal cavity, in lateral view (Fig. 52) elongate, dorsal half slightly wider than ventral half; gonite in ventral view (Fig. 53) triangular, with basal angle projected into narrow process, in lateral view (Fig. 54) obtusely angulate, extension toward aedeagal base slightly thinner; aedeagus in lateral view (Fig. 54) irregular, wider apically, margin irregular, in ventral view (Fig. 53) slightly wider subapically, irregularly rounded apically; phallapodeme in lateral view (Fig. 54) angulate, L-shaped, extension toward hypandrium shallowly angulate subapically, in ventral view (Fig. 53) spindle shaped, with basal portion much wider than apical portion; hypandrium in ventral view (Fig. 53) as a very wide and short structure, anterior and posterior emarginations shallow, anterior arms with oblique crossbar, in lateral view (Fig. 54) as an irregular H, with lateral portions of H irregular.

Type material.

The holotype male of Lamproclasiopa zerafael is labeled "BRAZIL. Amazonas: Reserva Ducke (02°55.8'S, 59°58.5'W; 40 m), 5 May 2010, D. & W. N. Mathis/ USNM ENT 00118311 [plastic bar code label]/HOLOTYPE ♂ Lamproclasiopa zerafael Costa, Mathis & Marinoni, INPA [red]." The holotype is double mounted (minuten pin in a plastic block), is in excellent condition, and is deposited in INPA. Fourteen paratypes (11♂, 2♀; DZUP, INPA, USNM) bear the same label data as the holotype. Other paratypes are as follows: BRAZIL. Amazonas: Manaus, Universidade Federal do Amazonas (03°05.9'S, 59°58.2'W; 50 m), 7 May 2010, D. and W. N. Mathis (5♂, 11♀; DZUP, INPA, USNM); Reserva Cuieiras (02°35.2'S, 60°07.2'W; 110 m), 8 May 2010, D. and W. N. Mathis (3♂; INPA, USNM).

Type locality.

Brazil. Amazonas: Reserva Ducke (02°55.8'S, 59°58.5'W; 40 m).

Distribution

(Fig. 104). Neotropical: Brazil (Amazonas).

Etymology.

The species epithet, zerafael , refers to José ( Zé) Albertino Rafael, student of Diptera and Zoraptera (especially the Amazonian fauna) and who kindly hosted and guided us while in Manaus, Amazonas. The name is a noun in apposition.

Remarks.

This species is distinguished from congeners, especially Lamproclasiopa triangularis , by having a sparsely microtomentose body generally, a mostly shiny black face; a short gena (height about half height of basal flagellomere), a hyaline wing, a blackish yellow foretarsus. The shape of structures of the male terminalia also distinguishes this species, especially the relatively gross, thickened aedeagus that is slightly asymmetrical, the wide and thinly dissected hypandrium, and the funnel-shaped gonites in ventral view.
