Hippopsis raberi View in CoL sp. nov.
( Figs 1–6 View FIGURES 1 – 10. 1 – 6 )
Description. Holotype male. Integument mostly black; mouthparts reddish-brown; gula and antennomeres brown. Pubescence yellow.
Head. Frons finely, sparsely punctate (punctures sparser, finer toward antennal tubercles); pubescence nearly obscuring integument, except glabrous longitudinal central area, distinctly widened between superior area of lower eye lobes; with one long, erect, dark seta close to lower eye lobes. Fronto-clypeal suture distinct laterally, gradually indistinct toward center. Median groove distinct from clypeus to prothoracic margin. Vertex moderately coarsely punctate (punctures more abundant between upper eye lobes, sparser toward area behind upper eye lobes); pubescence dense between antennal tubercles and closer to upper eye lobes, slightly sparser on remaining surface (partially rubbed in the holotype), not forming distinct bands. Area behind eyes moderately coarsely punctate close to eye, gradually finer, sparser toward prothoracic margin; tumid behind lower eye lobes; pubescence dense, obscuring integument (partially rubbed in the holotype). Antennal tubercles elevated in frontal view ( Fig. 4 View FIGURES 1 – 10. 1 – 6 ); apex of inner side forming triangular lobe; minutely, moderately abundantly punctate; pubescence partially obscuring integument. Genae very finely, transversely striate-punctate except smooth area close to apex; pubescence partially obscuring integument, except glabrous smooth area. Gula smooth, glabrous. Submentum with pubescence nearly obscuring integument, interspersed with some long, erect, dark setae. Postclypeus finely, moderately abundantly punctate centrally, gradually smooth toward sides; pubescence obscuring integument except on glabrous, narrow, longitudinal central area and sides, sparse on narrow transverse area close to anteclypeus; with long, erect, dark setae laterally on narrow transverse area close to anteclypeus. Labrum coplanar with anteclypeus on basal half, inclined on distal half; pubescence sparse (distinctly more abundant close to distal margin), interspersed with long, erect, dark setae, primarily on sides of basal half. Distance between upper eye lobes 0.12 times length of scape; in frontal view, distance between lower eye lobes 0.18 times length of scape; upper eye lobes with 7 rows of ommatidia. Antennae 4.5 times elytral length, reaching elytral apex at basal third of antennomere V; ventral side of scape, pedicel and antennomeres III–VI with long, erect dark setae, gradually shorter, sparser toward VI (on III and IV, about as long as diameter of antennomere); antennomeres VI–X with long, erect dark setae on apex; antennal formula (ratio) based on length of antennomere III: scape = 0.98; pedicel = 0.07; IV = 1.01; V = 1.03; VI = 1.04; VII = 1.05; VIII = 1.11; IX = 1.11; X = 1.08; XI = 1.08.
Thorax. Prothorax 1.25 times longer than wide; with 6 longitudinal, wide, dense bands of pubescence (area between these bands with pubescence exposing integument, primarily on pronotum): two on center of pronotum; one on each side of pronotum; one on each side of prothorax close to prosternum. Pronotum with slightly elevated longitudinal gibbosity centrally, between basal and distal transverse sulci; coarsely, moderately abundantly punctate. Sides of prothorax moderately finely punctate. Prosternum moderately finely, sparsely punctate close to procoxal cavities and base of prosternal process, smooth on remaining surface; with sparse pubescence laterally and on punctate area, nearly smooth on remaining surface. Prosternal process moderately finely, abundantly punctate; pubescence partially obscuring integument. Mesosternum and mesosternal process with pubescence partially obscuring integument; mesepisternum and mesepimeron fused, with pubescence obscuring integument, except glabrous narrow band close to mesepisternum. Metepisternum with pubescence obscuring integument, except narrow band close to elytra with pubescence exposing integument. Metasternum laterally and close to mesocoxal cavities with band of pubescence obscuring integument, except glabrous narrow band close to metepisternum; remaining surface with pubescence abundant, but not obscuring integument. Scutellum with pubescence abundant but not obscuring integument. Elytra. Moderately coarsely, abundantly punctate on basal third, gradually finer, sparser toward apex; apex concavely truncate, with outer angle distinctly projected and sutural angle slightly projected; each elytron with 3 longitudinal bands of pubescence, fused near apex: innermost band gradually inclined toward suture (reaching suture at about midlength); central band narrower than the others, placed near elytral curvature; outermost band gradually inclined toward epipleura (reaching epipleura at about midlength). Legs. Protarsomeres I–III wide; meso- and metatarsomeres elongated; metatarsomere I as long as II– III together.
Abdomen. Ventrites with band of dense pubescence laterally, primarily on I–III; remaining surface with abundant pubescence, partially obscuring integument; ventrite V with short, erect, sparse setae, and apex concavely truncate.
Dimensions in mm. Total length, 11.40; prothorax: length, 2.05; anterior width, 1.50; posterior width, 1.60; largest prothoracic width, 1.65; humeral width, 2.15; elytral length, 7.65.
Type material. Holotype male from PANAMA, Darién : Darién National Park ( Rancho Frio Station ; 90 m; 8.0198°N / 77.7322°W, 1.VI.2015, B. Raber col. ( TAMU) GoogleMaps .
Etymology. The new species is named after Brian Raber, collector of the holotype, colleague and personal friend of the third author.
Remarks. Hippopsis raberi sp. nov. belongs to the group of species with pronotum not transversely rugose and elytral apex concavely truncate. It resembles H. truncatella Bates, 1866 , but differs primarily as follows: in frontal view, head proportionally wider ( Fig. 4 View FIGURES 1 – 10. 1 – 6 ); vertex without distinct longitudinal bands of pubescence ( Fig. 6 View FIGURES 1 – 10. 1 – 6 ); pronotal punctures coarser ( Fig. 6 View FIGURES 1 – 10. 1 – 6 ); innermost longitudinal band of pubescence on elytra reaching suture ( Fig. 1 View FIGURES 1 – 10. 1 – 6 ); protarsomeres I–III wider ( Fig. 5 View FIGURES 1 – 10. 1 – 6 ). In H. truncatella , the head is proportionally narrower ( Fig. 8 View FIGURES 1 – 10. 1 – 6 ), vertex with longitudinal bands of pubescence ( Fig. 9 View FIGURES 1 – 10. 1 – 6 ), pronotal punctures finer ( Fig. 9 View FIGURES 1 – 10. 1 – 6 ), innermost longitudinal band of pubescence on elytra not reaching suture ( Fig. 7 View FIGURES 1 – 10. 1 – 6 ), and protarsomeres I–III distinctly narrower ( Fig. 10 View FIGURES 1 – 10. 1 – 6 ).
