Rhyopsocoides typhicolus View in CoL n. sp. ( Figs. 1–9 View FIGURES 1 – 9 )
Color. Straw yellowish. Compound eyes black. Mx3 and Mx4 reddish brown, strongly contrasting with color of rest of the body. Wings hyaline, veins pale brown.
Morphology. Body elongate, dorsoventrally flattened. Epicranial sulcus well defined, without lateral arms. Ocelli absent. Postclypeus with reticulate pattern ( Fig. 3 View FIGURES 1 – 9 ). Lacinial tips bifid, outer tine larger than inner one ( Fig. 2 View FIGURES 1 – 9 ). Mx4 apically blunt, wider in the middle, setae as illustrated ( Fig. 9 View FIGURES 1 – 9 ). Wings slender, elongate; forewing with pterostigma closed basally, M3 branched ( Fig.1 View FIGURES 1 – 9 ). Gonapophyses stout, with three apical setae, other setae as illustrated ( Fig. 7 View FIGURES 1 – 9 ). A large, stout biramous sclerite associated to the spermapore ( Fig. 8 View FIGURES 1 – 9 ). Spermathecal glands almost spherical, with pores and “finger print” marks ( Fig. 6 View FIGURES 1 – 9 ). Paraprocts elongate, with four trichobothria in line in sensory field; setae as illustrated ( Fig. 5 View FIGURES 1 – 9 ). Epiproct rounded posteriorly, with setal field as illustrated ( Fig. 4 View FIGURES 1 – 9 ).

Material studied. Holotype F. MEXICO. Colima. 5 km N Manzanillo, 2.XI.1988, on dead leaves of Typha sp., on edge of lagoon, A. N. García Aldrete. CNIN.
Etymology. The generic name means “ Rhyopsocus like”, in reference to the similarity in wing venation to that genus, the specific name refers to the plant on which the insect was found.
Remarks. Rhyopsocoides presents two autapomorphies that separate it from the other genera in the family, namely, M3 of forewing branched, and forewing slender, elongate, four times as long as wide; in addition, the strongly contrasting pigmentation of Mx3 and Mx4 could represent a third autapomorphy, but, as I have not seen all the species of the other psoquillid genera, I have chosen not to consider it, although there are no indications in the literature of that character in any psoquillid species. Rhyopsocoides is the sister group to the clade comprising Eosilla , Psoquilla , Rhyopsocus , Rhyopsocidus and Rhyopsoculus (personal information, unpublished). The relationships among the genera of the family Psoquillidae are presently being investigated, and preliminarily indicate that Rhyopsocoides is most similar to Rhyopsocus and Rhyopsocidus .
