Lachesilla distanti View in CoL n. sp. Female

( Figs 18–20 View FIGURES 18 – 20 )

Diagnosis. Micropterous. Subgenital plate broad, setose, straight posteriorly. Flap proximally narrow, wider in the middle, posteriorly concave. Gonapophyses stout, of sides parallel, distally rounded, with a sclerotized band along outer border and proximally. Ninth sternum wide in the middle, concave anteriorly, straight posteriorly, almost unpigmented, spermapore with a pigmented rim, located almost in the center.

Description. Color (24 years in 80% ethanol). Body reddish brown. Compound eyes black. Abdomen whitish, first abdominal tergite ochre, other tergites with pale brown subcuticular rings, faded ventrally.

Morphology. As in diagnosis, plus the following: ocelli absent, winglets triangular, compound eyes below the level of the vertex. Subgenital plate ( Fig. 18 View FIGURES 18 – 20 ). Gonapophyses and ninth sternum ( Fig. 19 View FIGURES 18 – 20 ). Paraprocts ( Fig. 20 View FIGURES 18 – 20 ) broadly elliptic, setae as illustrated, two macrosetae in the area of the sensory fields. Epiproct ( Fig. 20 View FIGURES 18 – 20 ) trapeziform, with setae as illustrated.

Measurements. F: 243, T: 394, t1: 112, t2: 71, ctt1: 8, Mx4: 133, f1: 130, f2: 100, f3: 93, f4: 89, f5: 85, f6: 79, f7: 61: f8: 56, f9: 61, f10: 59, IO: 502, D: 176, d: 132, IO/d: 3.80, PO: 0.75.

Specimen studied. Holotype female. MEXICO . Chiapas. 20 km W Tuxtla Gutiérrez , 1020 m. 30.iv.1993. Beating branches of tree in pasture land. A. N. García Aldrete ( CNIN).

Etymology. This species honors the memory of W. L. Distant, author of the Insecta. Rhynchota. Hemiptera- Heteroptera. Volume I (1880–1893), and co-author of the Insecta. Rhynchota. Hemiptera-Homoptera. Volume I (1881–1905), of the Biologia Centrali-Americana.

Remarks. L. albertina García Aldrete (1992) , L. buenoi García Aldrete (2017) , L. contrerasi García Aldrete (2015 b) , and L. michiliensis García Aldrete (1991) have micropterous or brachypterous females; L. distanti n. sp., differs from all of them in the shape of the subgenital plate, and in the shape of the gonapophyses and ninth sternum.
