Lachesilla godmani n. sp. Male

( Figs 31–33 )

Diagnosis. Hypandrium wide, with a setal field on each side, posterior processes lateral, proximally wide, curved outward, distally acuminate; phallosome V-shaped anteriorly, apodemes long, slender, with distal halves slightly dilated, smooth, distally acuminate.

Description. Color (36 years in 80% ethanol). Body reddish brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Antennae, maxillary palps and legs reddish brown. Wings hyaline, with an orange hue, veins reddish brown. Abdomen whitish, with ochre subcuticular rings, faded ventrally.

Morphology. As in diagnosis, plus the following: Compound eyes below the level of the slightly emarginate vertex. Forewing pterostigma wider distally, Rs-M fused for a distance, areola postica tall, apically rounded ( Fig. 31 ). Hypandrium and phallosome ( Fig. 32 ), a sclerotized band along posterior border of the hypandrium, between the posterior processes. Paraprocts ( Fig. 33 ) almost circular, setae as illustrated, a sclerotized band on inner borders, next sensory fields, these sensory fields with 11 trichobothria; mesal prongs slender, distally truncate. Epiproct ( Fig. 33 ) slightly concave anteriorly, bilobed posteriorly, setae as illustrated.

Specimen studied. Holotype male. MEXICO . Oaxaca. 9 km NW Telixtlahuaca. 5.vii.1981. Beating dead oak branches. A. N. García Aldrete ( CNIN).

Etymology. This species honors the memory of Frederick DuCane Godman, co-author of the Insecta. Lepidoptera. Rophalocera Volume I (1879–1901), Volume II (1887–1901) and Volume III (1879–1901), of the Biologia Centrali-Americana, and co-editor, with Osbert Salvin, of the same.

Remarks. In L. contrerasi García Aldrete (2015 b) , from the state of Hidalgo, L. curviforceps García Aldrete (1974 c) , from the states of Puebla, San Luis Potosí, Tamaulipas and Veracruz, L. gorhami n. sp., (described below, from Chiapas and Guatemala), and L. lachataoensis García Aldrete & Casasola (2012) , from Oaxaca, the posterior processes of the hypandrium are also lateral and curved outward, and the phallosomes are V-shaped anteriorly; however, in these species the structures mentioned are distinct and clearly separable from the structure of the hypandrium and phallosome in L. godmani n. sp.
