Map 12. Figure 38 (e–h).
Type locality. Costa Rica, Puntarenas, Est. las Alturas, 1500m, 8°56'N 82°50'W. Holotype female INBio.
Male. Male unknown.
Female. Head: Black. Face pale on lateral 1/5. Lunule wholly pale to pale only above antennal insertion, central black macula connected to frons color. Frons with white-silver pollen continuous from face and restricted to lateral margin, dull brown-pollinose medially. Vertex with black pile in a single median row; ocellar triangle ~2 times its length from posterior eye margin and ~1 ocellus-width from lateral eye margin. Eye with posterior indentation at level of antennal insertion. Antennal insertions separated. Occiput with dull dark pollen on dorsal 1/ 5, otherwise occiput with white pollen; dorsal ¼ of occiput with 1–2 rows of simple black pile, very short pile when anterior row present; middle ½ with 2–3 rows of scale-like white pile, anterior rows shorter; ventral ¼ with 2–3 irregular rows of scale-like white pile.
Thorax: Scutum black, mostly brown dull pollinose, except white on notopleuron and slightly posterior to transverse suture laterally, and with a pair of inconspicuous short sub-median tapering vittae of pale gray pollen; scutum with short white pile, except longer on notopleuron, and with anterior row of longer shining white pile, interrupted in the middle with shorter pile. Scutellum black, with metallic-shining pollen, with short white pile, subscutellar fringe pile long and white. Pleuron white pilose and black. Plumula white. Calypter white. Halter stem light brown, capitulum light orange.
Wing: Mostly hyaline with anterior margin dark brown (dark on cells bc, c, sc, r, r1 except for anterior subapical oval hyaline spot and r2+3 except hyaline on middle 3/5 of its posterior margin, most of bm light infuscated), entirely microtrichose; alula hyaline, basally 1.4 times to apically 3 times as broad as c cell, entirely microtrichose.
Legs: Proleg dark brown, profemur pale laterally and on apex, basal ½ of protibia pale, probasitarsomere light brown, other protarsomeres black, 2nd to 4th protarsomeres enlarged. Mesoleg dark brown, apex and apico-lateral 1/ 5 of mesofemur and basal 3/5 of mesotibia pale, mesobasitarsomere light brown, other mesotarsomeres black, 2nd to 4th mesotarsomeres enlarged, some ventral setae on mesotarsi orange. Metaleg dark brown, basal ⅓ of metafemur pale, apex of metafemur, base of metatibia, apical ⅓ of the metabasitarsomere until 3rd metatarsomere pale, 4th metatarsomere light brown, apical metatarsomere brown; metacoxa mainly white pilose, pile black ventrally.
Abdomen: Dark brown; ~4 times as long as thorax. First tergite white pilose. Second tergite long, length ~3 times minimum width, constricted medially, apex slightly wider than base, with pair of median sub-lateral oblique fasciate pale maculae; 2nd tergite with central triangular macula of dull black pollen, and mainly with short, appressed and black pile, except slightly longer, erect and white on baso-lateral ⅔. Third tergite trapezoidal, length ~1.5 times minimum width, with pair of baso-median quadrate pale maculae; 3rd tergite with central wide triangular macula of dull black pollen, and mainly with appressed and black pile, except white on baso-lateral corners. Fourth tergite rectangular and wide, entirely black; remaining characteristics as on 3rd. Fifth tergite rectangular, slightly wider than long; with appressed black pile. Sixth segment cylindrical long, ~2 times as long as 5th. Genitalia: 7th tergite mostly rounded apically but with short acute extension on apex, apical 2/5 pilose, basal extensions hyaline, inconspicuous, 4/5 of the length of the 6th segment; 7th segment lateral sclerite rectangular, narrowing to ½ its width apically, without baso-ventral extensions. Eighth tergite unsclerotized medially, basal crest normal, apex acute on lateral view; 8th sternite unsclerotized medially, short. Cercus fused dorsally, weakly sclerotized, with a ventral subbasal short extension.
Length. 11mm; wing 8mm.
Distribution. Costa Rica (Puntarenas).
Primary type. Holotype: Female in good condition with left proleg and genitalia dissected and placed in individual plastic tubes pinned with the specimen. Holotype labels: ‘Est. Las Alturas, 1 Km. Norte de Las // Alturas, Prov. Puntarenas, COSTA // RICA. 1500m. 12–19 AGO 1995. M. // A. Zumbado, L_S_322700_591400 // #6271’ ‘INBIO CRI002 388846’ ‘ Holotype // Pelecinobaccha tica // Miranda’ [red label].
Etymology. The specific epithet refers to how Costa Ricans call themselves, ‘tico’ for men and ‘tica’ for women. It is to be treated as a noun in apposition.
