Hypotelus scheerpeltzi Bortoluzzi & Caron View in CoL sp. nov.

( Figs. 11 View FIGURES 9 – 19 , 49 View FIGURES 48 – 58 , 73, 74 View FIGURES 59 – 74 , 82 View FIGURES 75 – 82 , 106, 107, 108 View FIGURES 83 – 108 , 113 View FIGURE 113 )

Type material. Holotype deposited in DZUP, male (photo, Fig. 11 View FIGURES 9 – 19 ) [damaged specimen: without right anterior leg, tibia and tarsus of right middle leg and tarsus of right hind leg. Dissected, body glued on white card; abdominal segments 8 to 10 and aedeagus fixed on acetate plastic card and covered with Canada balsam], with labels: (1) “ Peru / Lamas ” [old white label, printed in black]; (2) “ Coleção / M. Alvarenga ” [old white label, printed in black]; (3) “ ♂ ” [old white label, printed in black]; (4) “COTYPUS/ Hypotelus / Weyrauchi / O. Scheerpeltz ” [pink label, first and last lines printed in black, except the letter O; other lines, handwritten]; (5) “ HOLOTYPE / Hypotelus scheerpeltzi / Bortoluzzi & Caron ” [red label, printed in black].

Paratype: 1 female, deposited in DZUP [dissected, abdominal segments 8 to 10 and spermatheca fixed on acetate plastic card and covered with Canada balsam], with the same labels of holotype, except: (3) “ ♀ ” [old white label, printed in black]; (4) “ PARATYPE / Hypotelus scheerpeltzi / Bortoluzzi & Caron ” [yellow label, printed in black].

Diagnosis. Hypotelus scheerpeltzi sp. nov. may be distinguished from other species of Hypotelus by the color pattern of the elytra ( Fig. 11 View FIGURES 9 – 19 ); males are distinguished by median lobe of aedeagus thinner in lateral view and apex as a hook ( Fig. 73 View FIGURES 59 – 74 ); females are distinguished by the shape of tergite 10 and bursa copulatrix ( Figs. 106–108 View FIGURES 83 – 108 ).

Description. BL: 3.0– 3.3 mm, BW: 0.8 mm. Body slightly convex; dorsal surface glossy; dark brown, except elytra yellowish (with two transverse darker areas, basal and apical) ( Fig. 11 View FIGURES 9 – 19 ); appendages lighter, except mandibles and antennomeres 4–11. Dorsal integument of head and pronotum with dispersed fine punctures and undulate microstriae absent on basal disc of head and on disc of pronotum; elytra with dispersed fine punctures and only one longitudinal finely punctate stria close to elytral suture.

Male. Head. Supra-antennal area slightly prominent. Antennae inserted ventrally and passing 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=1.5); 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 basal two-third. Elytra somewhat longer than wide (EL/BW=1.2), can partially cover abdominal tergite 3.

Abdomen. Tergite 8 with posterior margin truncate ( Fig. 49 View FIGURES 48 – 58 ); sternite 8 at posterior margin with a small weakly pigmented strip and short setae; tergite 9 with short ventral struts; sternite 9 with posterior margin truncate and with two pairs of long setae; tergite 10 with posterior margin weakly pigmented, short fringes and four setae on each side. Median lobe of aedeagus with slightly bulbous base and apex somewhat pointed in ventral view; curved shape and thin in lateral view, with apex curved as a hook ( Figs. 73–74 View FIGURES 59 – 74 ).

Female. Similar to male except for: abdominal sternite 8 with posterior margin sinuous ( Fig. 82 View FIGURES 75 – 82 ); tergite 10 truncate at apex ( Fig. 107 View FIGURES 83 – 108 ); bursa copulatrix forming like a narrow ring ( Fig. 106 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. 108 View FIGURES 83 – 108 .

Geographical records. Peru (San Martín) ( Fig. 113 View FIGURE 113 ).

Biological notes. No data.

Etymology. The specific name refers to Otto Scheerpeltz, the researcher who first recognized it is as a new species but did not describe it.

Remarks. The type material bears a label handwritten by Otto Scheerpeltz, with the name “ Weyrauchi ” on it. A description for Hypotelus weyrauchi has never been published and is therefore treated as a manuscript name of O. Scheerpeltz. It is probable that there are other specimens labeled alike.
