ypes. -Holotype, male; data: NEW MEXICO. SAN MIGUEL Co.: Las Vegas,
1 Aug [no year], T. D. A. Cockerell, Chamaesaracha coronopus\ deposited: Amer¬
ican Museum of Natural History, New York.
Cockerell & Porter (1899) designated an unknown number of males and females
as the original type series. Cockerell (1937:3) later designated one male from this
series as the holotype
Description.—Female.— Head: (1) width 1.7-2.12 mm (5c = 1.95 ± 0.04; n = 10); (2) 1.39-1.47 (5c = 1.43 ± 0.01; n = 10) times broader than long; (3-19) as in C. persimilis except (7) head coloration dark brown to black with minute, creamy white spots on paraocular area immediately above man¬ dibular acetabulum in some specimens; (9) eyes blue. Mesosoma: (20-33) as in C. persimilis except20) lateral surfaces of pronotum distinctly shiny, glabrous, not imbricate; (26) intertegular distance 1.16-1.50 mm (5c = 1.30 ± 0.03; n = 10); (27) forewing length 3.40-4.20 mm (5c = 3.86 ± 0.08; n = 10); wings without dark spot at apex; (28) legs brown with white spots at base of both foretibia and mesotibia; mesobasitarsus broad (length 1.75-2.4 times width; Fig. 2g). Metasoma: (34-41) as in C. persimilis except (38) pygidial plate slightly more acute.
Male. —Head: (42) width 1.4-2.1 mm (x = 1.71 ± 0.04; n = 10); (43) 1.26-1.38 (* = 1.33 ± 0.01;
n = 10) times broader than long; (44) clypeus granulate-punctate; (45) frons shiny, glabrous except for widely-scattered punctation; (46) vertex shiny with scattered punctation; (47) gena weakly imbricate, shiny; (48) head black to dark brown with white maculation as in C. persimilis except less extensive, barely reaching above antennal sockets and often evanescent or absent on subantennal plates and subantennal area; (49) head setae as in C. persimilis but setae on clypeus much more dense, mostly obscuring surface of clypeus; (50-60) as in C. persimilis. Mesosoma: (61-72) as in C. persimilis except (61) lateral surface of pronotum more shiny; (67) intertegular distance 0.75-1.10 mm (5c = 0.99 ± 0.02; n = 25); (68) forewing length 3.20-4.65 mm (5c = 3.98 ± 0.06; n = 25); (69) yellow on legs as
in C. persimilis but dark spots on outer surface of mid and hind tibiae larger. Metasoma: (73-82) as
in C. persimilis except (76) T7 with broad (width >0.16 mm), weakly-defined, blunt pygidial plate
(Fig. 2f); surface mostly shiny, weakly rugulose; (78) median process on S5 shorter (length two-thirds width of stemite along midline; Fig. 2c); apex laterally flattened, blade-like with dense apical setae
(Fig. 2c); (79) apical prongs of S6 more slender in lateral view but with similar comb of setae (Fig. 2a); (80) S7 with distal lamellate lobes broad and horizontal (Fig. 2b); (81) S8 tapering to acute apex, not notched apically (Fig. 2d); (82) genital capsule as in Fig. 2e, foramen large.
Diagnosis. — This species is very similar to C. persimilis but is slightly larger and differs in the following structural features: Male: apex of S8 rounded, coming
to a point medially (Fig. 2d); apical prong of S5 less acutely pointed and shorter
(Fig. 2c); apical paired projections of S6 acutely pointed in lateral view (Fig. 2a);
large foramen in the genital capsule (Fig. 2e); male T7, pygidial plate broader and ess deeply concave (Fig. 2f); male clypeus with more dense covering of hairs, which overlap the labrum; yellow of clypeus rarely extending above the fronto-clypeal suture along midline of face. Female: pygidial plate more acute; meso-basitarsus broad (length 1.75-2.4 times width; Fig. 2g); black spot at apex of wing
lacking; well-developed yellow or white spot at base of pro- and mesotibiae; eyes
blue in pinned specimens.
