Hunting, Wesley M., 2013, A taxonomic revision of the Cymindis (Pinacodera) limbata species group (Coleoptera, Carabidae, Lebiini), including description of a new species from Florida, U. S. A., ZooKeys 259, pp. 1-73 : 14-15

Diagnosis.

Species in the limbata complex are distinguished by pale pronotal and elytral margins; several rows (two to four) of setigerous punctures extended the length of elytral interval 8. Most specimens of species in the limbata complex have contrasting punctation in alternate elytral intervals; intervals 1, 3 and 5 typically with one to two rows, interval 2, 4 and 6 typically with two to three rows. All species are macropterous.

Description.

With character states of limbata species group, restricted as follows.

Color. Dorsum of head, pronotum, and elytra testaceous to rufo- piceous, antennae testaceous to rufo-testaceous, palpi testaceous, abdominal sterna and other thoracic sclerites testaceous to rufo-piceous.

Microsculpture. Head capsule and pronotum smooth, microlines not evident at 50 ×. Elytra with mesh pattern isodiametric, microlines moderately deep.

Macrosculpture and pilosity. Head capsule with shallow, evenly scattered setigerous punctures on dorsal surface from constriction of neck extended anteriorly toward clypeus. Elytra with striae shallowly impressed and punctulate throughout length; intervals almost flat to slightly convex (few with greater convexity in intervals 1, 3 and 5), one-two (mostly one) irregular rows of fine punctules extended the length of intervals 1, 3 and 5; two-three or three (mostly two) irregular rows of fine punctules extended the length of intervals 2, 4 and 6; interval 8 with two to four rows of fine punctules extended the length of the interval. Abdominal sterna with fine pilose punctures throughout.

Fixed setae. Elytra with two setae in stria 3 and one posterior to end of stria 3; one seta at apex of interval 2; 15-17 lateral umbilical setae.

Pronotum. Anterior and posterior transverse impression shallow; median longitudinal impression shallow; posteriolateral angles almost right- angled to rounded; posterior margin slightly lobate.

Hind wings. Macropterous.

Male genitalia. Phallus anopic, cylindrical. Endophallus with a flat to slightly curved sclerite (endophallic plate) ( Lindroth 1969: 1080-1081) apically. Endophallus with or without microtrichial patch on basal lobe of everted sac.

Female genitalia. Gonocoxite 2 (gc2) short and stout to long and narrow. Internal genitalia with long cylindrical spermatheca (sp), associated spermathecal gland (sg), and spermathecal diverticulum (sd) located at base of spermathecal gland duct (sgd).

Geographical distribution.

The range of the limbata complex extends in eastern Canada from southern Quebec west to southern Ontario; in the eastern United States from Maine south to southern Florida, west to eastern Colorado and Nebraska, and south to southern Texas. In Mexico it is known from Nuevo Leon, Mexico, in the northern portion of the Sierra Madre Oriental.

Chorological affinities.

The geographical range of the limbata complex overlaps that of the punctigera complex and the chevrolati complex along the extreme southern and southwestern portion of its range.

Taxonomic composition.

Five taxa are included in this complex: Cymindis complanata Dejean; Cymindis limbata Dejean; Cymindis platicollis platicollis (Say); Cymindis platicollis atripennis (Casey); and Cymindis rufostigma sp. n.
