Diagnosis. Small (23.55 mm) scorpions. Color is brown, lighter on the legs, with underlying mottling on carapace and mesosoma. (see Figure 1). Pedipalp movable finger usually with 7 ID denticles and fixed finger usually with 6. Carapace of female is longer than the fifth metasomal segment. Pectinal tooth count for females 11.72 [n = 32], males 13.00 [n = 10]. Small, obsolete subaculear tubercle.

Type material. Holotype ♀, (N34.5201°, W111. 5074°), USA: Arizona: Coconino County, Mogollon Rim , 11 September 2011, leg. R. F. Ayrey, specimen RA269 ( USNM) GoogleMaps . Paratypes: same locality, 16 September 2011, leg. R GoogleMaps . F. Ayrey, 2 ♂ ( RA580 , RA581), 2 ♀ ( RA579 , RA583) ( RFA) .

Etymology. This species is named in honor of Trinity Frances Ayrey, my granddaughter and inspiration.

Distribution. Known only from the type locality: USA: Arizona: Coconino County, Mogollon Rim.

Description. Based on holotype female, unless otherwise noted. See Fig. 3 for dorsal and ventral views and

Table 1 for measurements of holotype and four paratypes.

Color. Color is brown, lighter on the legs. Faint underlying mottling on the carapace and mesosoma.

Carapace ( Fig. 4). Anterior margin of carapace moderately emarginated, posterior margin slightly emarginated. Carapace finely granular. Three lateral eyes on each side. Median furrow moderate and traverses entire length of carapace. Ratio of median eyes location from anterior edge/carapace length 0.69; carapace length/ width at median eyes 1.43. Carapace of female is longer than metasomal segment V.

Mesosoma ( Fig. 9). Tergites finely granular with vestigial median carina on Tergites I-VI. Tergite VII with weak median carina on anterior third and strong dorsal lateral and lateral supramedian granular carinae. Sternites III-VI finely granular and without carinae. Sternite VII with granular ventral lateral carinae on middle third. Presternites smooth. Spiracles ovoid with median side rotated 35º from posterior sternite margin. Sternites with variable number of microsetae.

Sternum. Sternum is type 2 (Soleglad & Fet, 2003) and is wider than long.

Genital Operculum. Sclerites separated on posterior one-fifth.

Pectines. Pectinal tooth count for the holotype female 10/10 and 14/15 for the paratype male. All pectinal teeth have exterodistal angling with large sensorial area. Middle lamellae 6/6. Fulcra are present. Each fulcrum with one central seta.

Metasoma ( Fig. 8). Carapace of female is longer than the fifth metasomal segment. Ratio of segment I length/ width 0.74;.of segment II length/width 0.97; of segment III length/width 0.99; of segment IV length/ width 1.34; of segment V length/width 2.05. Segments I-IV: dorsolateral carinae moderate, granular. Lateral supramedian carinae I-IV strong and granular with enlarged spinoid distal denticle on I & II. Lateral inframedian carinae moderately granular on segment I, posterior 3/5 of II, 2/5 of III, and obsolete on IV. Ventrolateral carinae I weak and granular; on II-III moderate, granular; on IV strong, granular. Ventral submedian carinae weak to moderate on segment I, moderate on II, moderate, granular on III and moderate to strong, granular on IV. Dorsal and lateral intercarinal spaces very finely granular. Segment I-IV ventral submedian setae 3/3. Segment V: Dorsolateral carinae weak, distally crenulate, basally granular Lateromedian carinae moderate, granular. Ventrolateral and ventromedian carinae moderate. Intercarinal spaces finely granular. Segment V ventrolateral setae 4/4.

Telson ( Fig. 7). Smooth with 4 pairs of large setae on the ventral surface, 3 large setae along both lateral edges of the vesicle and numerous smaller setae. Small, obsolete subaculear tubercle present.

Chelicerae ( Fig. 6). Dorsal edge of movable cheliceral finger with two subdistal (sd) denticles. Ventral edge is smooth, with well developed serrula on distal half.

Pedipalps ( Figs. 5, 10). Trichobothrial pattern type C ( Vachon, 1974) (see Fig. 10). Trichobothria ib and it located at base of fixed finger. Pedipalp ratios: chela length/width 3.88; femur length/width 3.39; patella length/width 3.14; fixed finger length/carapace length 0.72.

Chela ( Fig. 5). Carinae moderate. Fixed finger with median (MD) denticles aligned and divided into 6 subrows by 5 outer (OD) denticles and usually 6 ID denticles. Movable finger with 6 subrows, 5 OD denticles and usually 7 ID denticles (Soleglad & Sissom, 2001).
