Green Lacewing with Striped Legs - Eremochrysa tibialis

Green Lacewing with Striped Legs - Eremochrysa tibialis
Tonopah Desert, Maricopa County, Arizona, USA
May 11, 2015
Size: 6.5mm Body
This (brown colored) Green Lacewing has hexagonal wing cells, with banded veins that seem to indicate that this might be something in the genus Eremochrysa.
Note, the wings have small hairs and the stigma are almost completely colorless.

ID Update - Keying to species:
Here is a link to the key to the western species: (Banks 1950)(1)

Keying to species of Eremochrysa:
1. - Front and mid tibiae with a dark cross-band about one-third way from base, often also a dark spot at base of these tibiae; venation mostly dotted, vertex usually with reddish lines or spots = tibialis sp. nov.

I read the description for E. tibialis and most of it seems to match this specimen: (Here is a copy.)
Head, thorax, legs whitish; face with a reddish mark each side, divided inwardly; the upper, narrow part borders the antennal socket, the lower and broader reaching nearly to middle of face; clypeus with a dark median spot near lower edge, and a larger black spot at upper corner of clypeus, and extending a bit onto clypeus; cheek with a broad, dark brown (or rich brown) stripe, reaching to upper edge of clypeus; palpi dark, except tips of the joints. The basal antennal joint has a short black line or spot toward the inner tip; a black line on outer side and one above, and the second antennal joint dark (rich brown). The vertex has a dark spot each side on the raised area, with a short line extending forward, and a long dark spot close to the posterior part of eye; the collar (below the front of pronotum), has two dark brown marks on outer side.

The pronotum has a dark margin (formed of dark lines), broken near middle; there is a dark dot near the middle of front margin, another at middle before the cross-groove, and two behind the groove. The lateral lobes of meso- and metanotum have dark spots, and one on each lateral corner of the mid-lobe of mesonotum. Legs pale, all the tibiae have a dark dot near base, and a dark cross-line about one-third way down; the hind femur has a small dark spot near end.

The abdomen above is dull yellowish, with narrow dark hind borders on the segments, broader on the fourth and fifth segments. Pleura and venter dull, with a broad pale border to the fourth and fifth segments; the last two segments wholly pale. Apical process of male straight and rather stout, but tapering, with reclinate bristles, and some long, simple hairs. The tip of upper part has long, slender hairs; elsewhere the numerous hairs are extremely minute and very short, shorter than in E. fraterna.

The venation is mostly pale, with numerous dots, a few of the costals wholly dark; gradates partly dark, three inner, four outer. The divisory cell, rather slender, ends on the cross-vein above. Fifteen costals; eight radials; gradates parallel, inner about as near to radial sector as to outer series. In this male there is but one crossvein from the third cubital cell to margin, two from the fourth cubital cell. Length of fore wing, male 8.5 mm.; female 9.5 to 10 mm.

A male from Florence Jct., Arizona, 18 April 1935 (F. H. Parker) and many specimens from Watson, Utah, 22 July (F. M. Carpenter), also Vidal, California, 9 April (Sperry).

Type: M. C. Z. no. 28358.

I would say you are right
Based on what I've gathered about the genus, and following the description you quoted.

OK, someone deleted the species page. I will add it in today. Thanks for confirming the ID!

Moved from ID Request.

Rescued from evil bowl of water in kitchen sink!
Robert, I tried to capture the wing veins and hairs in one shot, but most of the hairs don't show up very well anyway. I had no idea that they were so hairy.
I'm guessing that the BugGuide needs a few more species pages, but that may take some time and I still have lots to learn about them.
Thanks for your help!
