Hemicaecilius mockfordi n. sp.

( Figs. 1–15 )

Female. Color. Body dark brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents ( Fig. 3 ). Distal segment of maxillary palps more pigmented than the others. Antennae and legs brown. Wings brown, opaque, R1 dark brown, much more pigmented than the other veins ( Figs 1, 2 and 15 ).

Morphology. Forewing L/W: 2.8; pterostigma long, wider posteriorly, lp/wp: 3.52. Areola postica triangular, slanted posteriorly ( Figs. 1 and 15 ). Hindwing L/W: 2.9 ( Fig. 2 ). Subgenital plate broad, setose; pigmented area concave anteriorly in the middle; posteriorly with two slender, slightly curved inward, acuminate projections of medium length ( Fig. 4 ); posterior border, between projections, straight, with small, pointed projections ( Fig. 4 ). Gonapophyses with proximal half broad, almost rectangular, bearing four setae; distal half triangular, wide based, distally acuminate, with two setae ( Fig. 6 ). Ninth sternum with two oblique, pigmented lines posterior to spermapore; this large, with a broad pigmented ring extended posteriorly in the middle; a large, irregular pigmented arch enclosing the spermapore ( Fig. 6 ). Paraprocts semicircular, setose, with sensory fields bearing ten trichobothria in basal rosettes ( Fig. 5 ). Epiproct trapeziform, with a field of setae on sides and along posterior border, as illustrated ( Fig. 5 ).

Measurements. FW: 1850, HW: 1437, F: 310, T: 585, t1: 202, t2: 92, ctt1: 16, Mx4:100, f1: 175, f2: 146, f3: 113, f4: 100, f5: 60, f6: 62, f7: 50, f8: 60, f9: 50, f10: 50, f11: 70, IO: 315, D: 95, d: 150, IO/d: 2.1.

Male. Color. Same as the female.

Morphology. Forewing L/W: 2.64. Pterostigma as in the female, lp/wp: 3.31. Areola postica triangular, not slanted posteriorly ( Figs. 7 and 14 ). Hindwing L/W: 2.96 ( Fig. 8 ). Hypandrium fused to the distal halves of the claspers, forming a long structure of two arms; each arm stout, wide based, long, distally acuminate, bent inwards ( Fig. 12 ); proximal half of each clasper large, irregularly rounded, with long setae over the surface, separated from the distal half by membranes ( Fig. 12 ). Phallosome ( Fig. 13 ). Paraprocts broad, sclerotized, setose as illustrated ( Figs. 10 and 11 ), with a long, slender, slightly curved mesal prong; sensory fields elliptic, with 9–10 trichobothria in basal rosettes. Epiproct trapeziform, posteriorly with a stout, sclerotized projection in the middle, distally truncate; a setal field on each postero-lateral corner, with long setae ( Figs. 10 and 11 ).

Measurements. FW: 2012, HW: 1575, F: 355, T: 650, t1: 210, t2: 95, ctt1: 18, Mx 4: 95, f1: 200, f2: 190, f3: 156, f4: 120, f5: 70, f6: 75, f7: 60, f8: 70, f9: 55, f10: 62, f11: 80, IO: 350, D: 100, d: 160, IO/d: 2.18.
