Lachesilla blandfordi View in CoL n. sp. Female

( Figs 4–7 View FIGURES 4 – 7 )

Diagnosis. Subgenital plate posteriorly concave, flap long, proximally narrow, with antero-lateral corners slightly projected outward, flap widening distally, posterior border rounded. Ninth sternum anteriorly straight, flanked by rounded areas with pigmented striae. Gonapophyses stout, distally rounded, with a pigmented band along outer border, slightly projected proximally.

Description. Color (43 years in 80% ethanol). Body tawny brown, compound eyes black, ocelli hyaline, without pigmented centripetal crescents. Maxillary palps dark brown. Antennae and legs pale brown. Wings hyaline, with a faint orange hue, veins brown. Abdomen whitish, with dark brown subcuticular rings, faded ventrally.

Morphology. As in diagnosis, plus the following: Forewing pterostigma elongate, wider posteriorly, Rs-M fused for a short distance, areola postica broadly triangular, apically rounded ( Fig. 4 View FIGURES 4 – 7 ). Subgenital plate broad, distally glabrous, setae as illustrated ( Fig. 5 View FIGURES 4 – 7 ). Gonapophyses ( Fig. 6 View FIGURES 4 – 7 ). Ninth sternum broadly pentagonal, posterior half unpigmented, spermapore with a sclerotized rim ( Fig. 6 View FIGURES 4 – 7 ). Paraprocts ( Fig. 7 View FIGURES 4 – 7 ) semi-elliptic, setae as illustrated, sensory fields with ten trichobothria. Epiproct ( Fig. 7 View FIGURES 4 – 7 ) wide, straight anteriorly, rounded posteriorly, with a field of setae on distal half.

Measurements. FW: 2105, HW: 1614, F: 405, T: 723, t1: 238, t2: 97, ctt1: 12, Mx4: 109, f1: 184, f2: 166, f3: 149, f4: 115, f5: 83, f6: 60, f7: 59, f8: 67, f9: 70, IO: 349, D: 153, d: 100, IO/d: 3.49, PO: 0.65.

Specimen studied. Holotype female. GUATEMALA. 4 km SE Patzún. 29.viii.1973. On Pinus sp. dead leaves. A. N. García Aldrete ( CNIN).

Etymology. This species honors the memory of W. F. H. Blandford, co-author of the Insecta. Coleoptera . Rhynchophora. Volume IV, Part 6 (1895–1907), of the Biologia Centrali-Americana.

Remarks. This species differs from the females of the other species in the group by the shape and size of the flap of the subgenital plate, and by the distinct, rounded striated areas that flank the anterior half of the ninth sternum.
