Hypotelus melanodelta Bortoluzzi & Caron View in CoL sp. nov.
( Figs. 13 View FIGURES 9 – 19 , 79 View FIGURES 75 – 82 , 91 View FIGURES 83 – 108 )
Type material. Holotype deposited in FMNH, female (photo, Fig. 13 View FIGURES 9 – 19 ) [damaged specimen: without right antennomeres 3–11. Dissected , body glued on white card; abdominal segments 8 to 10 and spermatheca fixed on acetate plastic card and covered with Canada balsam], with labels: (1) “ Columbia occ./ Cali, Fassl ” [old white label, printed in black]; (2) “ Chicago NHMus/ M.Bernhauer / Collection ” [old white label, printed in black]; (3) “ micans Shp. ?[?]/var/det. Bernh. ” [old white label, handwritten, last line printed in black]; (4) “ HOLOTYPE / Hypotelus melanodelta / Bortoluzzi & Caron ” [red label, printed in black].
Diagnosis. Hypotelus melanodelta sp. nov. may be distinguished from other species of Hypotelus by the large darker V-shaped area on the elytra and antennomeres 5–10 wider than long ( Fig. 13 View FIGURES 9 – 19 ); sternite 8 with posterior margin sinuous ( Fig. 79 View FIGURES 75 – 82 ).
Description. BL: 2.8 mm, BW: 0.7 mm. Body slightly convex; dorsal surface glossy; brownish, except elytra yellowish (with basal darker area forming somewhat an inverted triangle reaching the middle of elytral suture) ( Fig. 13 View FIGURES 9 – 19 ); legs reddish yellow. Dorsal integument of head and pronotum with dispersed fine punctures and undulate microstriae only on margins; elytra with dispersed fine punctures and only one longitudinal finely punctate stria close to elytral suture.
Female. Head. Supra-antennal area slightly prominent. Antennae reaching humeral angle; antennomeres 2 and 3 of equal length, antennomere 4 shortest and 5–10 wider than long; 11 longer than the preceding antennomeres.
Thorax. Pronotum wider than long (PW/PL=1.2); 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 half; one pair of conspicuous setae on anterior margin. Elytra somewhat longer than wide (EL/BW=1.2), not covering abdominal tergite 3.
Abdomen. Abdominal tergite 8 with posterior margin rounded; sternite 8 with posterior margin sinuous and with short setae ( Fig. 79 View FIGURES 75 – 82 ); tergite 10 with lateral and posterior margins weakly pigmented, with short fringes and four setae on each side at apex; bursa copulatrix as H. pusillus ; 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. 91 View FIGURES 83 – 108 . Male. Unknown.
Geographical records. Colombia.
Biological notes. No data.
Remarks. We received a single specimen (female) from FMNH identified previously as H. micans by Bernhauer, which we consider here as a new species, since the antennomeres 2 and 3 are the same length, in contrast to H. micans that antennomere 3 much shorter than 2 ( Sharp 1876, original description), besides the large darker area on elytra.
Etymology. The specific name refers to the dark color pattern of elytra and it is a compound name: Greek adjective melan - (black, dark), the connective vowel o, and the Greek noun delta (shaped like a triangle). It is a noun in apposition.
