Diagnosis

A. linnavuorii   is similar to A. rugosa Osborn, 1924   and A. affinis (Osborn, 1924)   in the shape of the pygofer but can be distinguished from them by the medially unproduced head (produced in A. rugosa   and A. affinis   ) and the shape of the aedeagus which, is longer, more bowed, and apex not spinose in the new species.

Etymology

This species is named in honor of Dr. Rauno E. Linnavuori, author of 5 valid tribes, 2 subtribes, 127 genera and 671 species of Deltocephalinae   .

Type material

Holotype

♂, PERU, Pasco, Villa Rica , 100 m, 23 Nov. 1971, R.T. & J.C. Schuh, coll. AMNH.

 

Paratypes

5 paratype ♂♂: sama data as holotype. Two specimens have an additional label reading: Collected on mud road in forested area just east of town. Two other specimens have pink labels, one with #2885 and the other with #2990. 2 paratypes are at AMNH and the remaining paratypes are at INHS.

Description

SIZE. ♂ 7.5-8.0 mm.

BODY. Head wider than pronotum. Crown dark brown to black in color, sometimes yellowish in part; not produced medially; median length equal to length next to eye; texture strongly striate to rugose; depressed; sharply angled to face. Ocelli on anterior margin of head; 2-3x their diameter from adjacent eyes. Face strongly rugose. Clypellus widening apically. Antennal ledges distinct. Pronotum yellow anteriorly, dark brown to black on posterior 2/3; carinate laterally; lateral carina longer than half basal width of eye. Mesonotum yellow with pair of dark spots medially. Forewing brown; claval veins yellow; sometimes with a few extra crossveins; usually with 1 to several crossveins between A1 and claval suture. Protrochanter with stout apical seta. Profemur row AM with AM1 only; intercalary row with long fine setae; row AV with ~4 to 7 relatively long thick setae. Protibia flattened dorsally; dorsal margins angulate; macrosetae 5+1. Mesotrochanter with stout apical PV seta. Mesofemur row AV with ~4 to 6 relatively long thick setae. Metafemur apical setae 2+1+1. Metatarsomere I plantar setae irregularly arranged.

MALE. Pygofer incised dorsally to midlength; with several rows of macrosetae on posterior half; hind margin notched posterodorsally; lobate ventrally; on either side of basolateral cleft, pygofer lobes overlap, with posterior lobe articulating with dorsal extension of subgenital plate. Subgenital plates constricted medially; macrosetae uniseriate distant from lateral margin. Connective Y -shaped; stem as long as or longer than anterior arms; articulate with aedeagus. Style broadly bilobed basally; apophysis short, digitate. Aedeagus with base of shaft tall, turning dorsad after some length; tapering apically; gonopore subapical on ventral side. Segment X strongly sclerotized dorsally; elongate, narrow; basally with protuberant dorsal lobe.

Remarks

One specimen is especially lightly pigmented but has identical male genitalia. Also collected at the same time were three specimens of A. rugosa   . These individuals, including the new species, were apparently mud-puddling, which has been reported before in A. affinis   by Rakitov et al. (2005).
