Material examined.

Holotype: Panama • 1 adult female; Parque Nacional San Lorenzo Canopy Crane , Colón; 9.2802°N, 79.9754°W; 15.i.2015; DA Peterson, GE Morse, H Shapiro, S Trujillo leg.; on Embothrium coccineum ; MIUP (D6581C) . Paratypes: • 1 adult female with second-instar exuviae; same data as holotype; USNM (D6581A) ; • 2 adult females; same data as holotype; UMEC (D6581B, D6581E) .

Description

(N = 4). Adult female not pupillarial. Appearance in life not recorded. Slide-mounted adult female 670-1450 μm long (holotype 670), 560-1100 μm wide (holotype 560), broadest at mesothorax or metathorax. Body outline turbinate to nearly oval. Derm membranous throughout at maturity except for pygidium. Antennae simple, each with one long seta. Distance between antennae 100-180 μm. Without disc pores associated with anterior or posterior spiracles. Lobes. L1 well developed, slightly wider than long, inner margins near parallel, with 1 notch on each side or without notches, rounded apically; space between lobes approximately 0.25 times width of L1. L2 and L3 absent. Plates cylindrical, narrow, pointed at apex, simple or with a few fine tines, about as long as L1; 2 plates present in first space, often with 1 or 2 tines near apex giving bifurcate or trifurcate appearance; 1 or 2 plates present in second space, simple or with minute tines; plates absent between L1. Ducts. Dorsal macroducts of 1-barred type, with 2-3 macroducts arising from first space, 8-10 arising from second space, and 7-8 arising from third space in singular rows. Series of marginal macroducts with wide orifices extending from mesothorax to abdominal segment II; at least two present per segment. Groups of ventral submarginal microducts occurring on head, thorax, and abdominal segments I-V. Paraphyses. With 1 pair of paraphysis-like basal scleroses near mesal margins of L1; 1 pair of paraphyses in first space, paraphysis arising from lateral margin of L1 slightly longer than paraphysis arising from medial margin of L2, both mushroom-like in shape with distinctive dome or cap at anterior end; 1 pair of small clavate paraphyses in second space. Anal opening longer than wide, 11-14 μm long, 5-7 μm wide, positioned 17-25 μm (1.5-2 anal lengths) from the base of L1, located within posterior third of pygidium. Perivulvar pores few, 2-6 pores in total, divided into 2-4 groups, with 1-4 in each group.

Remarks.

This new species is most similar in appearance to C. coursetiae (Marlatt) with subtle differences distinguishing the two. Submarginal groups of microducts form a semicircle around the head, thorax, and pre-pygidial abdominal segments of C. selvatica but are more diffusely scattered in C. coursetiae , not organized in an obvious semicircular ring. In C. selvatica , at least two large macroducts are present on the mesothorax, while in C. coursetiae only one at most is present, falling near the posterior margin of the mesothorax. The plates are nearly as long as L1 and fringed in C. selvatica but are short and simple in C. coursetiae . This species is also similar to C. subsimilis (Cockerell) in body shape and the shape of L1 but can be distinguished by possessing perivulvar pores on the pygidium (absent in C. subsimilis ).

Host plant.

Apeiba aspera Aubl. (family Malvaceae ).

Etymology.

The epithet Clavaspis selvatica is the Latin adjective meaning wild, literally "of the forest" (selva). Our choice of this name is influenced by the fact that in modern Spanish, the word selva is identical to its Latin ancestor in form, but now refers specifically to tropical rainforest.

Distribution.

Panama ( Colón).
