Zyzzogeton emmrichi View in CoL sp. nov.

( Figures 1 View Figure 1 A–H)

Description

Colour

Crown, pronotum, and mesonotum ( Figure 1A View Figure 1 ) mostly brown, without maculae; posterolateral and posterior margins of pronotum dark brown; mesonotum of a darker brown than crown and pronotum. Forewings ( Figures 1A, B View Figure 1 ) with corium and clavus mostly light green, with yellow costal macula on the apical third; costal margin and apical portion of corium (beyond clavus apex) brown. Face ( Figure 1C View Figure 1 ), lateroventral portions of thorax, and abdomen venter mostly brown.

Length

Length of male, 21.1 mm.

Morphology

Head ( Figure 1A View Figure 1 ) with crown moderately produced, median length considerably less than transocular width; coronal surface with scattered setae; apex of crown truncate, apical portion with pair of lateral conical protuberances ( Figures 1 View Figure 1 A–C) and shallow median fovea; transition from crown to face distinctly carinate medially; ocelli located on a line between anterior angles of eyes, each ocellus approximately equidistant from adjacent eye angle and median line of crown; surface of crown without distinct median fovea, without M-shaped elevation bordering posterior margin, with slight longitudinal carina laterad of each ocellus, with pair of lateral shallow foveae between eyes and ocelli; antennal ledges ( Figure 1A View Figure 1 ), in dorsal view, broadened toward apex, apical portion triangularly produced laterally, apex truncate. Face with frons concave on median portion; muscle impressions distinct, slightly prominent; epistomal suture indistinct; clypeus ( Figure 1C View Figure 1 ) strongly produced and angular in lateral aspect, carinate medially on inferior portion.

Thorax ( Figure 1A View Figure 1 ) with pronotum much wider than head; pronotum with anterior half of lateral margins convergent anteriorly, posterior half of lateral margins divergent anteriorly; disc surface rugose, punctate, and pubescent; with pair of very conspicuous, dorsolaterally directed conical protuberances ( Figures 1 View Figure 1 A–C) on posterior half; posterior margin of pronotum concave; dorsopleural carinae approximately rectilinear, declivous anteriorly. Forewings ( Figures 1A, B View Figure 1 ) with membranous area on apical portion (area beyond apex of clavus); veins elevated but not very distinct (except on membranous portion), veins of corium forming plexus ( Figure 1B View Figure 1 ) apically, with supernumerary anteapical crossveins to costal margin. Hindwings with vein R 2+3 complete. Hindlegs with femoral setal formula 2: 0: 0; first tarsomere shorter than combined length of second and third.

Male genitalia with pygofer ( Figure 1D View Figure 1 ), in lateral view, short; ventral portion longitudinally carinate; posterior margin sinuous with dentiform projection on superior portion; surface with microsetae mostly on and near ventral and posterior margins; pygofer without processes. Subgenital plates ( Figure 1E View Figure 1 ), in ventral view, completely fused basally (without line of fusion), then with line of fusion followed by completely fused area along preapical portion of distal half, clearly separated only on apical portion; plates extending posteriorly much beyond distal pygofer margin; basal third broader than remaining part of plates; apical portion, in lateral view, strongly curved dorsally, forming angle of almost 90 ° with remaining part of plates; apex broadly rounded; surface with numerous microsetae. Valve ( Figure 1E View Figure 1 , VLV), in ventral view, fused to subgenital plates. Connective ( Figure 1F View Figure 1 ), in dorsal view, Yshaped, stem longer than arms with pair of median longitudinal keels. Styles ( Figure 1F View Figure 1 ), in dorsal view, extending posteriorly much beyond apex of connective; without preapical lobe but with distinct, large lobe on median outer portion ( Figure 1F View Figure 1 , OSL); with microsetae on apical portion externally; apical portion digitiform, apex slightly curved inwards. Aedeagus ( Figure 1G View Figure 1 ) symmetrical, slender, elongate; apical portion, in lateral view, curved dorsally with pair of apical processes, each one with two projections ( Figure 1H View Figure 1 ), anterior projection, in dorsal view, smaller, triangular, acute, posterior projection digitiform; gonopore ( Figure 1G View Figure 1 ) preapical, located on ventral margin just before pair of processes. Abdominal segment X (base of anal tube) ( Figure 1D View Figure 1 , LAT), in lateral view, large, conspicuously lobed lateroventrally.

Material

Holotype, male: ‘‘N. [Nueva] Gran. [Granada]’’; ‘‘ Caucathal [Valle del Cauca Department, Colombia]\428’’ ( MTD).

Etymology

The new species is described in honor of Dr Rainer Emmrich (Museum für Tierkunde in Dresden; retired), who published fine contributions on the taxonomy of the Proconiini and arranged the loan of the holotype and other interesting specimens of the tribe.
