Hypotelus testaceus Bierig, 1934: 342 View in CoL (original description, type locality: “ Panamá, cercanía de France Field ( Zona del Canal)”); Herman, 2001: 1786 (distribution).
Type material. Hypotelus testaceus Bierig, 1934: 342 . Four syntypes deposited in FMNH . One female [dissected, abdominal segments 8 to 10 were fixed on acetate plastic card and covered with Canada balsam], with labels: (1) “ France Field/ VI.1930 / Panamá ” [white label, handwritten]; (2) “ TYPUS ” [black label, handwritten]; (3) “ Hypotelus / testaceus / Brg. ” [white label, handwritten]; (4) “ Field Mus. Nat. Hist. /1966/ A. Bierig Colln. / Acc . Z13812 View Materials ” [white label, printed in black]; (5) “FMNHINS/0000 131 009” [white label, printed in black]; (6) “ Photographed / Kelsey Keaton 2014/ Emu Catalog ”[blue label, printed in black]; (7) “ SYNTYPE / Hypotelus testaceus / Bierig , 1934 /det. S. Bortoluzzi, 2016” [red label, printed in black]. Three specimens, one male [dissected], one female [dissected] and one sex undetermined, whit same labels: (1) “ France Field/ VI.1930 / Panamá ” [white label, handwritten]; (2) “ Field Mus. Nat. Hist. /1966/ A. Bierig Colln. / Acc. Z-13812” [white label, printed in black]; (3) “ SYNTYPE / Hypotelus testaceus / Bierig, 1934 /det. S. Bortoluzzi, 2016” [red label, printed in black].
Note: In the original description, Bierig (1934) did not specify how many specimens he observed. We received from FMNH four specimens, one specimen with label “TYPUS”, but we consider all of them as syntypes.
Diagnosis. Hypotelus testaceus may be distinguished from other species of Hypotelus by the body color (see Redescription); male with sternite 8 at posterior margin with short tricuspidate projection medially ( Fig. 53 View FIGURES 48 – 58 ); sternite 8 of female with posterior margin sinuous and shape of spermatheca ( Figs. 88–90 View FIGURES 83 – 108 ).
Redescription. BL: 2.6–3.0 mm, BW: 0.6–0.8 mm. Body somewhat slightly convex; dorsal surface glossy; brown; basal two-thirds of elytra, apical thirds of abdominal segments 3–6 and appendages lighter than body, except mandibles ( Fig. 12 View FIGURES 9 – 19 ). Dorsal integument of head and pronotum entirely with fine punctures and undulate microstriae; elytra with dispersed fine punctures and only one longitudinal finely punctate stria close to elytral suture.
Male. Head. Supra-antennal area slightly prominent. Antennae reaching humeral angle; antennomeres 2 and 3 of equal length, 5–11 gradually increasing in length toward antennal apex. Mandibles symmetrical.
Thorax. Pronotum wider than long (PW/PL=1.4); anterior angles rounded and slightly prominent; apical half with somewhat parallel sides and basal half gradually narrowing toward the base; with complete internal midlongitudinal ridge and slight longitudinal median sulcus only on disc. Elytra somewhat longer than wide (EL/ BW=1.2), not covering abdominal tergite 3.
Abdomen. Tergite 8 with posterior margin rounded; sternite 8 with posterior margin with short tricuspidate projection at middle region and with short setae ( Fig. 53 View FIGURES 48 – 58 ); tergite 9 with short ventral struts; sternite 9 with posterior margin truncate and with two pairs of long setae. Median lobe of aedeagus with bulbous base and apex triangular in ventral view and curved shape in lateral, with apex curved as a hook ( Figs. 65–66 View FIGURES 59 – 74 ).
Female. Similar to male except for: abdominal sternite 8 with posterior margin sinuous ( Fig. 78 View FIGURES 75 – 82 ); tergite 9 without ventral struts; tergite 10 with lateral and posterior margin weakly pigmented ( Fig. 89 View FIGURES 83 – 108 ); bursa copulatrix as Fig. 88 View FIGURES 83 – 108 ; ovipositor consisting of a pair of weakly pigmented hemisternites and a pair of more apical coxites, and with many long setae on apex; spermatheca as Fig. 90 View FIGURES 83 – 108 .
Geographical records. Panama (Colon) ( Fig. 114 View FIGURE 114 ).
Biological notes. No data.
Remarks. In the original description, Bierig (1934) reported that the male of this species is unknown. In the type material, we found one male and it is described it here for the first time.
