Cyptophania costalis n.sp.

Diagnosis. No distinct whorls of microtriches on antennal flagellomeres beyond f1. Fore wing venation not visible. Ctenidia absent on hind t1. A single tergite sclerotized and pigmented before clunium. See also Key.

Female color (in alcohol 26–51 years). Compound eyes black. Rest of head and prothorax beige to medium brown. Other body parts and appendages medium to light brown (material from Veracruz with slightly rusty hue). Fore wing mottled with colorless areas on brown background ( Fig. 35 ).

Female structural characters. Whorls of microtriches absent on antennal flagellar segments except for extremely vague whorls on some middle segments. Long setae on all antennal flagellomeres, in subapical whorls on f1–f17, the whorls becoming median and less regular on f18 outward. Lacinial tip ( Figs 36–38 ): lateral tine with distinctly double-tipped outer denticle, large, pointed inner denticle, large, pointed median tine. Fore wing venation not visible. Hind wing a minute cuticular flap. Hind coxal rasp ( Figs 39–41 ) slender to moderately broad, occupying about half of inner edge of coxa. Trichobothrium-like setae absent on hind tibia. Hind tibial spurs striated. Ctenidia absent on hind t1. Pretarsal claw with a few lateral spinelets ( Fig. 42 ). One abdominal tergite before clunium sclerotized and pigmented. Ovipositor valvulae ( Fig. 43 ): v1 weakly to moderately sclerotized beyond basal stem. Collar of spermathecal duct ( Figs 44–46 ) short, its orifice near distal end; a short appendage terminating in one or two points near orifice. Cutter of spermathecal sac ( Figs 47, 48 ) curved, occupying about half length of sac in slide preparation. Spermathecal gland reticulate. Telson lobes as described for the genus.

Female measurements (µm). BL = 1808, FW = 715, F = 522, T = 750, t1 = 302, t2 = 58, t3 = 63, f1 = 43, f2 = 41, f3 = 46, f4 = 42, IO = 438, d = 104, D = 226, IO/d = 4.19, IO/D = 1.93.

Material examined. Mexico: Veracruz: Tuxpan, 16–17 August 1965, sifting litter on beach, coll. ELM, 3 female paratypes and 6 nymphs ( ELM). Puerto Rico: San Juan:, 14 August 1961, sifting ground litter, coll. ELM, holotype female (on slide and in alcohol), 5 female paratypes and 7 nymphs ( INHS except 1 paratype ELM). USA: Florida: Monroe Co.: Boca Chica Key, 27 October 1986, coll. J. Wolff, 1 female paratype ( ELM).

Etymology. The name refers to the coastal situation in which each of the collections was made.

Note. Minor differences can be observed among the three populations dealt with here as a single species. Among the 15 characters compared, the single Florida specimen stands apart from the Mexican and Puerto Rican specimens by having a slightly thinner lacinial tip, obvious mottling on the fore wing, and a slightly shorter and thicker hind coxal rasp. The spermathecal cutter appears to be more pointed in the Florida and Mexican specimens than in those from Puerto Rico, but that may be a question of differences in orientation on the slide preparation. Minor differences are seen in the tip of the appendage of the collar of the spermathecal duct, but these cannot be evaluated for lack of enough material. Since the differences noted are minor, and no differences were seen in 10 of the 15 characters, it seems reasonable to treat the three populations as a single species at least until additional material allows more detailed comparisons. It seems likely in view of the absence of males and the small size and wrinkled appearance of the spermathecal sac in each case, that they all represent a parthenogenetic complex found throughout the seacoasts of the area.
