Anillinus sinuaticollis Jeannel

(Map fig. 40)

Anillinus sinuaticollis Jeannel, 1963 b:152 . Holotype female glued on rectangle and labeled /Roane Co., Tenn., Feb 23, 38, T-9135 38 -2819/ from soil of peach orchards/ Anillinus sp. /TYPE/ Anillinus sinuaticollis typ R.Jeannel det., 19 / TYPE No 69541 USNM/ deposited USNM.

Holotype examined. Specimen is in good condition, not damaged or dissected.

Description. Small-sized for genus (ABL, 1.51 mm). Habitus subconvex, parallel-sided and elongate (WE/ABL, 0.35) with relatively large head (WH/WPm, 0.79) and narrow pronotum and elytra (WPm/WE, 0.85). Color of body rufotestaceous, appendages testaceous. Dorsal microsculpture indistinct on disc of pronotum, distinct along base of pronotum. Head with distinct microsculpture.

Pronotum moderately convex and transverse (WPm/LP, 1.31), margins moderately constricted posteriad and slightly sinuate before posterior angles (WPm/WPp, 1.28). Anterior angles evident, slightly prominent. Posterior angles nearly rectangular. Width between posterior angles approximately the same as between anterior angles (WPa/WPp, 1.01).

Elytra markedly convex, slightly depressed along suture, relatively short (LE/ABL, 0.56), with traces of only 2 interneurs. Humeri prominent, slightly rounded. Vestiture of elytra short. Genitalia not examined.

Distribution. Known only from the holotype from Roane Co., Tennessee ( Fig. 40).

Habitat. Type specimen bears the label ‘‘from soil of peach orchards.’’

Differential Diagnosis. Anillinus sinuaticollis is the single member of parallelsided species with distinct microsculpture on the head ( Table 2, group V of endogean species). The combination of microsculptured head with absence of microsculpture on the pronotum distinguish these species from the others. Additional specimens and aedeagal examination are required for further diagnosis.
