Balboana cameroni Evans 1966

Balboana cameroni new species
Holotype. — 5, Costa Rica: Turrialba, 31 May 1944 (F. Schrader) [USNM].
A specimen of this species from Volcan de Chiriqui, Panama (GCC), is labeled "Pseudagenia hecuba Cam.", but so far as I can determine Cameron never actually described such a species. This species is of about the same size and general appearance as the preceding, but there are enough differences in color, wing venation, and shape of the propodeum to convince me that each deserves specific status.
Description of type female. — Length 13 mm.; fore wing 10.5 mm. Black, marked with ferruginous as follows: antennal segments 4-6 and apex of 3; greater part of clypeus; labrum, mandibles, and palpi; legs, including all coxae, except tibiae and tarsi darker, suffused with fuscous; spurs straw-colored; extreme tip of abdomen weakly suffused with rufous. Pubescence in large part silvery, especially dense and conspicuous on the lower pleura, posterior half of propodeum, and basal portions of abdominal segments; on the vertex, thoracic dorsum, and apices of basal abdominal terga, the pubescence is brownish; front coxae and propodeum with only some very fine, short, pale setae. Hind wings hyaline except the tip weakly infuscated; fore wings hyaline, with a strong whitish spot just outside SMC3, banded with brownish as follows: basal half and apical .4 of anal cell; a broad band across the transverse median and basal veins, extending to fill the basal half of SMC1; a small spot at apex of second discoidal cell; a broad band filling the basal two-thirds of the marginal cell, SMCs 2 and 3, and the outer half of the third discoidal cells, more or less confluent with a weaker band filling the space beyond the third discoidal cell and extending along the outer wing margin. Labrum partially exserted, with a broadly V-shaped apical emargination. Clypeus about as wide as lower front, narrowly separated from the margins on each side, measuring 2.6 X as wide as high, the apical margin broadly truncate, slightly depressed and contracted on the sides. Head 1.15 X as wide as high; MID .50 X TFD; UID .73 X LID, .78 X MID; POL:OOL = 5:4. Third antennal segment 4 X as long as its apical thickness, subequal in length to UID; ninth antennal segment about twice as long as thick, about half the length of the third. Pronotum broadly subangulate behind. Propodeum rather flat in front, with an abrupt, oblique declivity on the posterior third, with some fairly strong rugae on the margin
of the declivity. Middle and hind tibiae with the spines short and sparse, the upper surface of the hind tibiae with very scattered, minute spines. Marginal cell rather pointed, removed from wing tip by only slightly more than half its own length; stigma .47 X as long as marginal cell; basal vein arising from media slightly basad of junction of transverse median vein; SMC2 small, only slightly wider than high; SMC3 also small, much wider below than second but not wider on the radial vein than SMC2; distance from third intercubital vein to tip of marginal cell 1.25 X distance from that vein to stigma. Abdomen weakly compressed apically.
Allotype. — s, Costa Rica: Turrialba, Aug. 1963 (CCP) Description of allotype male. — Length 6 mm.; fore wing 6 mm. Body black, the following parts whitish: apical third of clypeus, lower inner orbits, posterior margin of pronotum, a large spot on apical tergite; labrum and mandibles largely testaceous; antennae pale ferruginous on basal half, deeply infuscated beyond segment six; legs dusky ferruginous, including all coxae, except middle and hind tibiae and tarsi moderately infuscated; tibial spurs white and hind tibiae with a small basal white spot. Wings hyaline, fore wing with a brownish band across the basal and transverse median veins and a broader band filling the marginal cell and extending to the lower wing margin, where it meets a weaker band along the outer margin. Body pubescence coarse, whitish; erect hairs of head and thorax very short, pale, inconspicuous. Labrum with a median notch; clypeus broadly truncate, 2.4 X as wide as high. Head 1.2 X as wide as high, the vertex smoothly arcuate; MID .52 X TFD; UID very slightly exceeding LID; POL:OOL = 3:2. First four antennal segments in a ratio of 15:5:20:17, segment three about 3 X as long as thick; segments 3-5 are slender, unmodified, segments 6-9 and also 12 are somewhat rounded below, segments 10 and 11 are more strongly produced below and each bears a conspicuous sensorium on the apical third. Postnotum a transverse band which is not produced backward medially; propodeum with a strong median impression. Legs rather weakly spinose; longer spur of hind tibia nearly as long as basitarsus. Fore wing as described for the female except SMC3 slightly wider on the radial vein than SMC2, distance from third intercubital vein to tip of marginal cell slightly less than distance from that vein to stigma. Abdomen strongly compressed; SGP very slender and pointed, its sides not expanded at the base (fig. 74). Genitalia as shown in fig. 62, differing from those of auripennis especially in having the apical part of the digiti devoid of setae.
Distribution. — Costa Rica and western Panama. (Map 32.) Paratypes. — Costa Rica: 1 2 , same data as type except 14 May
1944 [MCZ]. Panama: 1 2, Volcan de Chiriqui, 2000-3000 feet
Variation. — The second Turrialba specimen is smaller than the type (fore wing 8.5 mm.) and has the front very narrow, MID .49 X TFD; it is otherwise very similar to the type. The Chiriqui female has the fore wing 9.5 mm. long, the front somewhat broader, MID .52 X TFD; in this specimen antennal segment three measures 1.1 X UID and is more than twice the length of segment nine; aside from some minor deviations from the wing pattern of the type, there are no noticeable color differences.
