description: Lagideus boyaca Smith, new species
(Figs. 3, 4, 16, 27, 31)
Female. Length, 9.5 mm. Antenna and head black, mandible reddish brown. Thorax black. Legs yellow orange with coxae black, except fore and midcoxae with apex white and yellow orange on outer surface and extreme apices of tarsomeres white. Abdomen orange, segments 4–6 with narrow anterior margins black, segment 7 black with posterior margin yellow, segments 8 and 9 and sheath black. Wings hyaline with slight yellow tinge; veins and stigma black. Head: Covered with golden-yellow hairs equal in length to diameter of ocellus; shiny, frons with few, scattered fine punctures. Antennal length about 1.5 × head width; antennomeres 3–7 serrate, each broader at apex than at base; antennomeres 3 and 4 subequal in length; antennomeres 5–7 about 2 × longer than broad. Malar space half or less diameter of front ocellus. Thorax: Hind basitarsomere slightly longer than length of remaining tarsomeres combined; inner hind tibial spur about 0.75 length of hind basitarsomere. Abdomen: Sheath rounded at apex in lateral view; in dorsal view broad at base tapering to acute apex, with long lateral hairs (similar to Smith 1990: fig. 293). Lancet (Fig. 16) with 13–14 serrulae with those basally and centrally deeper than apical ones; serrulae with fine anterior and posterior subbasal teeth; annuli 1–5 with very short hairs, annulus 6 with longer hairs almost a third width of segment, annuli 7–11 dorsally with long spines nearly width of segments and ventrally with shorter, less dense hairs, annuli 12 to apex without hairs.
Male. Length, 7.5 mm. Similar to female, except legs entirely orange; pronotum, mesepisternum, mesonotum, and metascutellum orange, and abdomen black with basal plates orange. Antenna (Fig. 24) with antennomeres 3–8 bifurcate, inner ramus of antennomere 3 long, about half length of outer ramus, apical antennomere with length of fork equal to stem. Genitalia as in Figs. 27, 31; apex of parameres rounded, central indentation about half of paramere length; penis valve with valviceps rounded and relatively straight at apex and with dorso-apical lobe.
Type material. Holotype female “ Colombia: Boyaca, SFF Iguaque, 5°25’12”N, 73°27’24”W, 2975m, M.29, Malaise 8, April 1–19, 2000 P. Reina” (HUM). Paratypes: Colombia: Boyaca, Arcabuco, SFF Iguaque, Malaise 7, 2820m, Feb. 28–March 17, 2000, P. Reina, collector (1 Ƥ, USNM); Colombia: Cundinamarca, PNN Chingaza Bosque Palacio, 2930m, 4°31’00”N, 73°45’00”W, July 21-August 3, 2000, M.359, E. Raigoso (1 3, HUM); Colombia: Cundinamarca, PNN Chingaza Bosque Palacio, 4°31’N, 73°45’W, 2930m, Malaise, 3/3/01 – 3/16/01, C. Vinchira & A. Cifuentes leg., M.1492 (1 3, USNM).
Etymology. Named for the type locality, Department of Boyacá, a noun in apposition.
Remarks. This species goes to L. cellius Smith, 1990, couplet 4 in my 1990 key, which was described from Roraima, Brazil. The color of the two are very similar. However, Lagideus cellius has the lateral portions of the lateral lobes brown, hind legs with the apical quarter of the femur and apical two-thirds of the tibia black, malar space equal to the diameter of the front ocellus, hind basitarsomere longer than remaining tarsomeres combined, inner hind tibial spur about 0.66 the length of the hind basitarsomere, and the lancet with dorsal half of annuli 4–10 with long stout spines about half the width of the segments. The male of L. cellius is not known. The male of L. boyaca is associated somewhat by the similar color of the female, but primarily by the similar long golden hairs on the head and thorax. The hairs of the head and thorax of other males I have seen are white. The male will not key in my 1990 revision because I had no males with a long inner ramus on antennomere 3 at that time. The male of L. schmidti described below has similar antennae, but in that species the thorax is entirely black and the head and thorax are covered with white hairs. See the preceding revised key to males for separation from other known males.
