Four new species of Eriophyoid mites from Brazil (Acarina, Eriophyoidea)

Abstract

ABSTRACT. Tegonolus lricarinalus n.sp. , Floracarus claviger n.sp., Cosella callipodex o.sp. and Aculus verrUCOSllS n.sp., Acarina, Eriophyoidea, fram Brazil are described and tigured. KEY WORDS. Eriophyoidea, Teg011011lS, Floracarus, Cosella, AculllS, taxonomy A survey on Brazilian plant feeding mites yielded four new species. These are herein described and figured . Measurements represent range, in micrometers. Those of setae are the longest able to be measured since setae are not always in horizontal position and often have very fine tips and break easily off.Tegonotus tricarinatus, n.sp. Fig. 1Diagnose. T. Iricarinalus is the third species described from a Leguminosae host and is distinctive in presenting the first tergite (dorsal annulus) twice as long as each ofthe remain ing ones. Tn the general body outline it resembles T. marinalni (Keifer, 1939), except for the first long tergite. Its opisthosoma presents a longitudinal middorsal conspicuous ridge extending over tergites 2-11/ 13, as in T. marinalni, but is distinctive in having two longitudinal dorsolateral ridges extending from tergites 7-18 (4th tergite from rear), absent in T. marinalni. Dorsal shield setae are well ahead from shield rear margin and dorsal shield is smooth except for two short longitudinal lines in midfield, as in T. scoticus Roivainen, 1950, however, in this latter species the middorsal ridge is very moderate and extends over the entire opisthosoma.Female. Ali Illeasurements are reported in Illicrollleters. Description from six specimens, 140-156 long, spindle shaped, 70-76 wide at the broadest point. Gnathosoma directed downward, 30-31 long; basal setae 5-8 long; antapical setae 4-5 long; chelicerae 19-25 longo Prodorsal shield (including frontal lobe) 51-57 long, 69-75 wide, fi'ontal lobe 13-14 long; lightly punctate, punctuations barely visible. A short pair 01' admedian lines. Dorsal tubercles well ahead 01' shield rear margin, 25-29 apart, directing prodorsal setae upward and centrad; setae 5-9 longo Legs with ali normal setae. Legs l, 32-34 10ng; trochanters 3 long; temora 8-10 long, femoral setae 8-11 long; genua 3-5 long, genual setae 18-21 long; tibiae 6-8 long,

The First Records of Three Eriophyid Mite Species (Acari: Eriophyidae) in Latvia

“…In 2020, two more species were added to the list: Anthocoptes masseei (Nalepa 1925) associated with blackcurrant (Salmane et al 2020) and Aceria erinea damaging walnut (Stalažs et al 2020). Aceria erinea is an alien species of Latvia anf it has been actively spreading across Europe over the last twenty years (Flechtmann et al 2002, Hulme 2009, Stalažs et al 2020.…”

Three eriophyoidea (Acari: Prostigmata) new for the brazilian fauna

“…1) DIAGNOSIS -C. latiscuta is the second Brazilian species in this genus and it is described from the same area as C. callipoda Flechtmann, 1996. It can be distinguished by the broadly rectangular dorsal shield (nearly as long as wide in C. deleoni (Keifer, 1956) and C. cissi Keifer, 1978; ellyptical in C. ichnocarpasia Mondal and Chakrabarti, 1981 and C. callipoda Flechtmann, 1996; semicircular in C. simplicis Manson, 1984) and by the granulated hind coxae, as in C. deleoni (coxae spinulate or with lines in the other species). FEMALE (n = 10) (Measurements of holotype and range of paratypes in parentheses) -From front of shield to terminal lobes 185 (169-198) long; 74 (69-75) wide.…”

“…E T Y M O L O G Y -latiscuta,derived from latus, a Latin word, meaning wide, broad, and scuta, from scutum, Latin, meaning shield, referring to the relative width of the prodorsal shield. Feminine, as Cosella (Amrine, Stasny and Flechtmann, 1996). Keifer, 1960 (Fig.…”
