Prolachesilla casasolaoides  n. sp. Male

( Figs 16–20View FIGURES 16 – 20)

Diagnosis. Differing from P. casasolai  n. sp., in having the phallosome with one body of endophallic denticles and in having the external parameres shorter, broader, with spiny apices shorter, curved outwards ( Fig. 19View FIGURES 16 – 20). Arms of the aedeagal arch shorter than in P. casasolai  ( Fig. 19View FIGURES 16 – 20); posterior border of the hypandrium similarly biconcave, but the postero-lateral corners are distinctly rounded ( Fig. 20View FIGURES 16 – 20). Clunial projection over the area of the epiproct wider and deeper than in P. casasolai  ; projections over the area of the paraprocts larger than in P. casasolai  ( Fig. 18View FIGURES 16 – 20). Differing from all the other species of Prolachesilla  in the arrangement of the endophallic denticles and in the shape of the posterior border of the hypandrium.

Color. Body tawny brown, compound eyes black, legs pale brown, forewings pale yellow, hindwings hyaline, almost transparent ( Fig. 16View FIGURES 16 – 20). Tergal lobes of meso- and metathorax pale brown, abdomen creamy with pale brown subcuticular, transverse bands.

Morphology. As in diagnosis plus the following: Head vertex almost straight, slightly below the level of the upper borders of the compound eyes, these large, prominent ( Fig. 17View FIGURES 16 – 20). Forewing L/W: 2.53 ( Fig. 16View FIGURES 16 – 20). Forewing pterostigma elongate, wider distally, lp/wp: 3.09, without setae in the membrane. Areola postica triangular ( Fig. 16View FIGURES 16 – 20). Hindwing L/W: 2.89 ( Fig. 16View FIGURES 16 – 20). Hypandrium ( Fig. 20View FIGURES 16 – 20) and phallosome ( Fig. 19View FIGURES 16 – 20) as in diagnosis ( Fig. 19View FIGURES 16 – 20). Paraprocts ( Fig. 18View FIGURES 16 – 20), oval; sensory fields with 15 trichobothria on basal rosettes. Epiproct ( Fig. 18View FIGURES 16 – 20), almost trapeziform, slightly rounded posteriorly, setae as illustrated.

Specimens studied. Holotype male. MEXICO  . Oaxaca. Sierra Juárez  . Santa Catarina  Lachatao, “ Las Vigas ”, 17°11’17”N: 96°27’13.5”W, 2790 m., 27.VIII.2013, beating shrubs with dead, hanging leaves, J. A. Casasola González.

Etymology. The specific name refers to the similarity with P. casasolai  n. sp., both species are sympatric, found in the same biotope, date and locality.
