Rather, such variability resulted from the indiscriminate use of traits from three unrelated lineages. From the morphological variability described above we identified three different morphological groups. These morphological groups also correspond to the three unrelated Xestoblatta lineages retrieved in our phylogeny.</p> <p>Our morphological analysis show that different lineages of Blattellidae can be differentiated by the type of tergal modification in the abdomen in males. Brossut &amp; Roth (1977) had already suggested the usefulness of this trait in cockroach taxonomy. Species of the three Xestoblatta lineages can be easily differentiated by the location on abdominal segments I, II, III or VII and by the shape of the tergal modification. On the other hand, assigning females to each lineage continues to be a challenge based only on external morphological characters, and more so in groups morphologically homogeneous as these. Tentatively, body length helps to differentiate females of lineages 2 and 3, being smaller in the latter (less than 19 mm).</p> <p>Rehn (1951) considered wing venation a useful trait to discriminate groups of species in cockroaches. Similarly, Gurney (1939) based on this trait recognized two groups of Xestoblatta species, species with ulnar vein of the hind wings with up to nine branches and species with ulnar vein with more than nine branches. Our analysis showed that despite the high variability of this trait among all the reviewed species, even the intraspecific variation, two groups of species are recognized in agreement with Gurney (1939): species of lineages 1 and 2 with ulnar vein with at least eight branches while species of lineage 3 with ulnar vein with maximum of six branches. According to this, only lineage 3 can be differentiated using this trait from the other two lineages. It is still necessary to add more species in each Xestoblatta lineage to determine the potential taxonomic use of this trait, which appears to be homoplastic.</p> <p>Male genitalia in cockroaches are structurally complex and, as in many other insects, are highly divergent between species (Klass 1997). The process “via” and the sclerite R have the highest interspecific variability. The first character has unique shapes in each species and apparently there are not morphological patterns. In contrast, the sclerite R shows distinct patterns that allows differentiating the three Xestoblatta lineages. For instance, the subregions R1v and R2i and the region R3 tend to be similar in shape and/or complexity within lineage. However, morphometric studies are necessary to quantify the variation in the shapes of these genital structures and thus corroborate these the morphological patterns.</p> </div>	http://treatment.plazi.org/id/A22A39604F7CFFBD39CC3C457BF3F9CE	Public Domain	No known copyright restrictions apply.

The generic name refers to the tergal modification on abdominal segment VII with pocket form, which is unique in the species of this genus. Sinatablatta (in spanish “cucarachas con bolsillo”). Sinus (latin) = pocket.</p> <p>Distribution and biology. Currently, Sinatablatta gen.n. ranges from southern Mexico to southern Brazil (Fig. 1C). The distribution range of this genus and Xestoblatta (sensu stricto) widely overlap (Figs 1C, D). However, Sinatablatta gen.n. has not been recorded in the Guiana shield. Cockroaches are, in general, rarely collected, so the lack of sampling may explain the absence of this genus in this region of South America.At eight locations in Central America, the northern Andes, and the Amazon, we simultaneously collected specimens of Sinatablatta gen.n. and Xestoblatta (sensu stricto). The existence of sympatry between species suggest that these lineages likely share similar biogeographic histories. All species within Sinatablatta gen.n. were observed active during the first hours at night on the vegetation either at low height or on the litter. These cockroaches are strongly attracted to carrion.</p> </div>	http://treatment.plazi.org/id/A22A39604F79FFA639CC3E957C0AFDFA	Public Domain	No known copyright restrictions apply.

The right style located at the end of a column-like projection formed by the projection of the plate from right posterior margin (Fig. 5E).</p> <p>Genital sclerites. Sclerite L2 thin and elongated with region L2a strongly sclerotized unlike the process “via” which is imperceptible (Fig. 5F). The sclerotized region of hla-hook (sclerite L3) with distal area narrow and elongated. In addition to the notch “45”, the hook also exhibits groove “hge” along of its lower margin (Fig. 5G). Basal area of L3 three times longer than its apical area. Membranous tube of hla-hook bare. Sclerite L4 as a strongly sclerotized dorso-lateral plate, except in X. zeteki where is absent.</p> <p>Genital sclerite R formed by the sclerotized regions R1, R2 and R3 (Figs 5H–J). Region R1 as a large and bulky structure at the right postero-lateral region of sclerite R. Upper right corner of R1 (R1c) articulated with lower right corner of region R3 (articulation A3). Subregion R1v extends anteriorly to R 1t partially covering the R 1t +R2 complex. Subregion R 1t merged with region R2, forming the complex R 1t +R2. R2 longer than R 1t. Both elongated and pointed but only apex of R2 extending beyond posterior margin of R3. Subregion R2i articulated from its quadrangular base with left corner of posterior margin of R3. R2i with two projections, proximal projection shorter and thinner than the distal one, and the distal one generally with multiple short digitiform projections with spiniform apexes (Fig. 5J), except in X. zeteki. Region R3 as a slightly sclerotized triangle shaped plate. Corners of posterior margin not aligned, left corner relative to right corner displaced vertically upwards more one-third the length of the right side of R3 (Fig. 5I). Region R4 only present in X. zeteki as a weakly sclerotized plate.</p> <p>Distribution and Biology. Xestoblatta (sensu stricto) species range from southern Mexico to southern Brazil (Fig. 1D). All species of Xestoblatta (sensu stricto) were observed active during the first hours of the night on the vegetation at low altitude and on the litter. These insects are strongly attracted to carrion.</p> </div>	http://treatment.plazi.org/id/A22A39604F66FFA539CC3A607D1CFB0A	Public Domain	No known copyright restrictions apply.
