Locality and horizon.

Upper Kalkschieferzone member of Meride Limestone (transition interval to Archelaus and Regoledanus Ammonoid Zones, upper Ladinian), Middle Triassic; VM 12 site (DMS geographical coordinates: 45°53’26’’N; 8°56’49’’E), Val Mara near Meride , Monte San Giorgio, Switzerland GoogleMaps .

Etymology.

The specific epithet is the Latin numeral secundus, meaning “ second ”, and refers to this as the second described species of the genus.

Diagnosis.

Forewing characters only: ma-mp as long as r-ma; distal-most cell between R and MA two times as long as wide.

Description.

Body 1.4 mm long, presence of long macrosetae on the head, thorax, and some wing veins. Head: head apparently orthognathous to prognathous, with a relatively long buccal cone; compound eyes rounded with diameter 0.1 mm; [antenna not preserved]. Thorax: 0.37 mm long, 0.4 mm high; legs partly preserved. Abdomen: broad, 0.9 mm long, 0.7 mm wide; cerci absent. Forewing venation: forewing 1.7 mm long, 0.8 mm wide, pear-shaped, rounded apically, narrow basally; a common stem ScP + R + M + CuA; CuA, cua-cup, and CuP not visible; ScP re-emerging from R 0.8 mm from wing base, perpendicular to C and R, straight, 0.15 mm long; M separating from R 0.6 mm distal of base of CuA; stem of M curved, 0.5 mm long, separating into MA and MP and delimiting a broad elongate closed cell, 0.4 mm long, 0.19 mm wide; both MA and MP with a strong angle distally and ending on posterior margin at right angle; a long ma-mp perpendicular to MA and MP; two elongate, broad cells between R and MA, separated by r-ma perpendicular to R and MA, basal-most cell 0.4 mm long, 0.15 mm wide; distal-most cell 0.46 mm long, 0.23 mm wide; R forming an angle distal of ScP and straight distally, separating into RA and RP 0.5 mm distal of ScP; RA straight, short, rather oblique, nearly orthogonal with RP; RP forming a strong angle, reaching wing apex; straight, elongate rp-ma, 0.12 mm long.
