Bioacoustics of Typhlocharis toletana

Description of the adult : Length of holotype : 1.2 mm . Length of paratypes : 1.1–1.3 mm . Body long, depressed and parallel, light brownish. Integument microreticulate, mesh pattern isodiametric, with scattered short setae. Head capsule ( Fig. 2 a) robust, slightly narrower than pronotum and almost as wide ( 0.27 mm .) as long ( 0.29 mm .), slightly depressed in the middle of the frons, with two frontal divergent depressions delimiting it. Dorsal surface reticulate, except stridulatory area without microlines ( Fig. 2 f). Clypeus without median tooth. Anophthalmous. Appendages: antennomeres 1–2 cylindrical, 3–11 moniliform ( Fig. 2 c); labial mentum with one tooth and lateral lobes rounded ( Fig. 2 b); penultimate labial palpomere thickened, ultimate palpomere minute. Setation: clypeus with two setae, the external pair longer than the internal; cephalic capsule with 3–4 frontal setae, two median, and three large periorbital setae (supraorbital plus temporal); cephalic capsule and lateral carina with some other minor setae; labrum with five setae, three short and medial, one long and lateral and one external to the latter; labial mentum with two pairs of long setae, one close to the base of tooth and another on the lateral lobes, prebasally there are two other lateral pairs of setae. Prothorax. Pronotum ( Fig. 2 d) longer ( 0.35 mm ) than wide ( 0.29 mm ), surface microreticulate, slightly trapezoidal with maximum width close to the apical margin. Disc flattened. Anterior margin slightly arcuate. Sides slightly crenulate only in the posterior quarter. Hind angle obtuse and distinctly marked with a small acute tooth. Posterior margin arcuate. One seta in anterior quarter of lateral margin and another on hind angle. Three longitudinal series of minute setae. Six pairs of strong setae on the anterior margin and two pairs of setae on the posterior margin. Both anterior and posterior margins with a row of tomentose setae. Prosternum with sparse and short setae. Elytra ( Fig. 2 g; 2h; 2j) twice longer ( 0.60 mm ) than wide ( 0.28 mm ), totally reticulate, with longitudinal carina at seventh stria slight and short, not extended to the apical margin of elytron (it disappears in the posterior fifth), and thus without forming there a small dentiform projection. Basal and lateral margins perpendicular, humeral region clearly marked and humeral angle smoothly rounded. Sides parallel with lateral margin slightly serrate to posterior quarter. Sutural angle not dentate ( Fig. 2 h). There are four longitudinal series of setae. Lateral margin with four setae in the anterior umbilicate group and three setae in the posterior group ( Fig. 2 j). First ventrite of female with slight lateral fovea ( Fig. 2 i). Legs similar in both sexes without special features such as dentiform projections or distally dilated femora. Front tibia with antenna cleaner (toilette organ) long and regularly arcuate, with one securiform clip seta at its proximal border ( Fig. 2 e), also reported in other species (e.g., T. gonzaloi : Ortuño 2005 ; T. martini Andujar et al. 2008 ). Trochanter long with rounded apex ( Fig. 3 a), similar in male and female. Median lobe of male genitalia ( Fig. 3 b) slightly curved, ventral side almost straight and dorsal side with a membranous appearance to the apex. Apex short and acute. Internal sac with a small sclerotized piece. Parameres with two apical setae. Gonocoxite 2 of IX gonocoxa of female genitalia unguiform ( Fig. 3 a), with one internal seta and two external nematiform setae. Spermatheca rounded, sclerotized, spermathecal gland distally dilated. Description of the larva: Material studied . Twenty apparently older-instar larvae were collected in the type locality, ten in June 19, 2007 and another ten in November 12, 2007 . Larvae were labelled “ SPAIN Villarrubia de Santiago Toledo 19.VI-–2007 Spring on a hillside 590m N 40, 0 2 W -3,30 Andújar and Lencina leg., and “ SPAIN Villarrubia de Santiago Toledo 15.IX-2007 Spring on a hillside 590 m N 40, 0 2 W -3,30 Andújar, Lencina and Sánchez leg.. Five larvae of these two dates were mounted on Euparal microscope slides and stored at the Canadian National Collection of Insects, Arachnids and Nematodes, Ottawa, Canada . Larvae are not designated as type specimens.
