<p class="Body"><strong>New</strong><strong> </strong><strong>and interesting galumnoid mites (Acari, Oribatida, Galumnoidea) from Malaysia</strong></p>

This work includes taxonomic and faunistic data on oribatid mites (Oribatida) of the superfamily Galumnoidea which were collected in Malaysia. Two new species are described. Galumna perakensis sp. nov. differs from Galumna alata, G. cavernalis and G. tokyoensis by the costate prodorsum and reticulate pteromorphs. Pergalumna titiwangsaensis sp. nov. differs from Pergalumna paraindistincta by the pointed rostrum and relatively long anal setae. Five species (Allogalumna dilatata, A. indonesiensis, Carinogalumna philippinensis, Galumna granalata, Pergalumna paraindistincta), one subgenus (Flagellozetes (Cosmogalumna)) and one genus (Carinogalumna) are recorded in Malaysia for the first time.</jats:p

Neotrombicula elegans Schluger 1966

Neotrombicula elegans Schluger, 1966 Material examined. Location A: 24 larvae from Pellorneum ruficeps (Passeriformes: Pellorneidae), 1 February 2010; 1 larva from Larvivora sibilans (Passeriformes: Muscicapidae), 4 February 2010; larva from Pellorneum ruficeps; 4 February 2010; 2 larvae from Turdus dissimilis (Passeriformes: Turdidae), 4 February 2010. Distribution and hosts. N. elegans infests small rodents Apodemus agrarius, Apodemus flavicollis (Melchior), Apodemus sylvaticus (Linnaeus) (Rodentia: Muridae), Myodes glareolus Schreber, and Microtus arvalis (Pallas) (Rodentia: Critedidae) in Ukraine (Kudryashova 1998). Larvae found in Slovakia were isolated from soil samples (Kalúz & Vrabec 2014). We found N. elegans in Vietnam for the first time. Pellorneum ruficeps, Larvivora sibilans and Turdus dissimilis are new hosts for this chigger. Remarks. Chiggers of this species from Vietnam are identical with N. elegans from Ukraine and Slovakia. The measurements of individuals of N. elegans are presented here: Vietnam (this paper): AW 66–74, PW 83–91, ASB 29–34, PSB 25–34, SD 57–68, SB 29–33, AP 28–34, H 51–56, AM 45–49, AL 45–49, PL 48–52, DS 34–36, VS 30–34, NDV 66–70, S 67–77, pa 278–314, pm 249–289, pp 289–316, Ip 841–902.

SIF = 7B.S-B-3-3111.A000; fsp = 7-7-7; fPp = B.B.bBB; Ga = B; Pc = 3; fSc = AL&gt; PL&gt; AM; SB//PL; fCx = 1.1.1; fSt = 2.2; fD = 2H+8.6.6.4.4.2 = 32; DS = 32; VS = 28; NDV = 60; Ip = 869 (852&ndash;902).&lt;/p&gt; &lt;p&gt; &lt;i&gt;Idiosoma&lt;/i&gt; (Figs. 6, 7). Scutum nearly as wide as long, bearing AM, AL, PL setae and distally expanded (rounded) sensilla (20 long, 18 wide). Posterior part of scutum partially submerged beneath the cuticular striae of dorsum. Posterior striae create concentric pattern in each of lateral halves of scutum. Anterior margin of scutum sinuous with &ldquo;shoulders&rdquo;, lateral margins conical with small medial protrusion. Scutal puncta spread and cover anterior and lateral parts of scutum. Scutal ridge present connecting both bases of sensilla. Rounded eyes (2 + 2) in ocular plate, anterior eye larger than posterior. Humeral setae 57 (54&ndash;61) long, dorsal setae 46 (43&ndash;51) long, arranged in regular rows, the posteriad rows varying in position of setae.

Sternal area with two pairs of sternal setae (fSt = 2.2), fCx = 1.1.1. Ventral side with 28 irregularly arranged ciliated setae. Lengths of ventral setae vary, increase from anterior 29 (26&ndash;32) to median 32 (29&ndash;36) and posterior 39 (36&ndash;43).&lt;/p&gt; &lt;p&gt; &lt;i&gt;Gnathosoma&lt;/i&gt; (Fig. 8). Galeala barbed (Ga = B). Palps 71 (67&ndash;82) long, palpotibial claw 21 (18&ndash;23) long with 3 deeply indented prongs. Chelicera anteriorly with tricuspid cap.&lt;/p&gt; &lt;p&gt; &lt;i&gt;Legs&lt;/i&gt; (Fig. 9). With pretarsus, claws and normal empodia. All setae on legs ciliated, slender. Specialized setae on leg segments&mdash;Leg I: Tarsus&mdash;S1 17, f1 3, nude pretarsala 11 (PT&acute;= N), ciliated ST 32 and nude pST 20, 2 tibialae (anterior 20 and posterior 18), microtibiala 3, 3 genualae&mdash;anterior 17, median 23 and posterior 20, microgenuala 3; Leg II: Tarsus&mdash;nude pretarsala 11 (PT&acute;&acute;= N), S2 15, f2 3, 2 tibialae&mdash;anterior 16, posterior 16, genuala 17; Leg III: mastitarsala 56 (A-type; by Vercammen-Grandjean 1968) with 3&ndash;4 cilia, tibiala 17 and genuala 18. Number of barbed setae on leg segments (leg formula from coxa to tarsus): Leg I: 1-1- 1-5-4-8-20; Leg II: 1-1- 2 -4-3-5-16; Leg III: 1-1- 2 -3-3-5-14. Length of tarsi I&ndash;III: I&mdash;82 (80&ndash;83), II&mdash;65 (63&ndash;69), III&mdash;81 (78&ndash;84). Width of tarsi I&ndash;III: I&mdash;18 (17&ndash;20); II&mdash;17 (16&ndash;18); III&mdash;17 (16&ndash;17). Leg length: pa = 308 (301&ndash;320); pm = 264 (258&ndash; 274); pp = 297 (285&ndash;305); Ip = 869 (848&ndash;902).&lt;/p&gt; &lt;p&gt; &lt;b&gt;Differential diagnosis.&lt;/b&gt; The new species is very morphologically close to &lt;i&gt;Neoschoengastia posekanyi&lt;/i&gt; Wharton and Hardcastle, 1946 but differs by having Ga = B; AW 47 (46&ndash;49); PW 64 (63&ndash;67); SB 39 (36&ndash;42). Moreover, tarsus III bears A-type (branched in base) mastisetae and striae on the posterior part of the scutum are concentric. &lt;i&gt;N. posekanyi&lt;/i&gt; differs from new species in having Ga = N; AW 75; PW 80; SB 47 and tarsus III with nude mastisetae. In this species parallel striae on the scutum are posteriorly horizontal. Another species close to the newly described species is &lt;i&gt;Neoschoengastia heynemani&lt;/i&gt; Nadchatram and Upham,1966. &lt;i&gt;N. heynemani&lt;/i&gt; differs from &lt;i&gt;Neoschoengastia vietnamensis&lt;/i&gt; sp. nov. by SIF = 7B.S-N-3-3111.0000, Ga = N, fPp = B.N.NNB, clavate but narrow apical part of sensillum and by lacking mastisetae on the tarsus III. Other differences are in the scutal formula (fSc: PL &ge; 2AM&gt; AL) and length of leg III (pp. 263&ndash;270). On the contrary, &lt;i&gt;Neoschoengastia vietnamensis&lt;/i&gt; sp. nov. has SIF = 7B.S-B-3-3111.A000; Ga = B, and fPp = B.B.NbB. The newly described species has also apically broad rounded sensilla, longer leg III (pp = 285&ndash;305) and fSc: PL&gt; AM&gt; AL, where PL is little longer than AM.&lt;/p&gt;Published as part of &lt;i&gt;Kaluz, Stanislav, Hung, Nguyen Manh, Capek, Miroslav &amp; Literak, Ivan, 2016, Two new species and new records of chiggers (Acari: Leeuwenhoekiidae, Trombiculidae) from birds in Vietnam, pp. 483-503 in Zootaxa 4061 (5)&lt;/i&gt; on pages 491-496, DOI: 10.11646/zootaxa.4061.5.2, &lt;a href="http://zenodo.org/record/267719"&gt;http://zenodo.org/record/267719&lt;/a&gt
