Palpipalpus Beard and Seeman, gen. nov.
No full textPalpipalpus Beard and Seeman gen. nov. Type species. Palpipalpus hesperius Beard and Seeman Diagnosis. All life stages: dorsal opisthosoma with 13 pairs of strongly barbed setae; c 2, d 2, e 2, and f 2 present; setae e 2 and f 2 inserted in more-or-less marginal position; setae h 2 similar in size and form to other dorsal setae; palps 5 -segmented, setal formula 0, 0, 0, 2, 3 (1); immature stages with anterior margin of prodorsum smoothly rounded, without projections/notches; ventral plate absent; 2 pairs of pseudanal setae (ps 1–2) on weakly developed anal plates. Adult female: gnathosoma partially concealed by anterior margin of prodorsum (also in male); anterior margin of prodorsum with 1 pair of rounded lobes anterior to, but not bearing, setae v 2 (also in male); genital plate weakly developed, membranous; metapodal plates not developed; coxae I without 1 c; trochanters I–IV 1 - 1 -2- 1; femora I–IV 3 - 3 - 2 - 1; genua 2 - 2 -0-0 (setae d and l′′ present); tibiae 4 - 4 - 3 - 3; tarsi I–IV with tc′′. Solenidia of male much thicker and longer than in female. Etymology. The name Palpipalpus is derived from palpus (a feeler) and is repeated to emphasise and allude to the swollen sensory solenidia of the palps and tarsi I–II in the male. Remarks. Palpipalpus most closely resembles Crossipalpus, with both genera sharing males with enlarged solenidia and only two pairs of ps setae. Palpipalpus differs to Crossipalpus by the presence of prodorsal lobes, seta tc′′ on tarsi I–IV, seta f 2 on the dorsal opisthosoma, and the palp tibial seta (all absent in Crossipalpus).Published as part of Beard, Jennifer J., Seeman, Owen D. & Bauchan, Gary R., 2014, Tenuipalpidae (Acari: Trombidiformes) from Casuarinaceae (Fagales), pp. 1-157 in Zootaxa 3778 (1) on pages 80-81, DOI: 10.11646/zootaxa.3778.1.1, http://zenodo.org/record/25133

Lamington NP, ex M. quaestionis. 2 females, Box Forest Circuit, 13.ii.1996, O. Seeman, beetle #321 (log 1, passalid 1) (QMS 109464–5); 2 females, same data except beetle #322 (log 2, passalid 2) (QMS 109462–3); 1 major male, same data except beetle #332 (log 3, passalid 3) (QMS 109466). Goomburra State Forest, ex M. australasicus (southern form). 1 female, 1 major male, 27°58′S 153°30′E, 18.iv.2012, H. Urbina, J. Bartlett & O. Seeman, beetle BG 12-4-18-14-6-1 (QMS 109474– 5). Jimna State Forest, ex Pharochilus dilatatus. 4 females, 1 major male, 1 minor male, Peter’s Rd, Sunday Ck, 17.iii.1996, O. Seeman, beetle #201 (QMS 109467–72). 1 female, 2 km E Sunday Ck, 17.iii.1996, O. Seeman, beetle #197 (QMS 109473). All in QM. Imbil, ex passalid. 1 major male, 11.ix.1946, F.J. Gay (on several slides: J17337 –43, J17356). 1 female, same data (on several slides: J17345 –17352). 1 female, same data (two slides: J17317, J17344). Lamington NP, ex passalid. 1 female, 1 major male, H. Womersley, 1949 (J17329, J17313). All in SAM. Diagnosis. As per Seeman (2017). Remarks. This common species from southeast Queensland is often found on Mastachilus quaestionis, Australia’s largest passalid beetle, but was also recorded from M. australasicus (the southern form only) and P. dilatatus. Mastachilus quaestionis is found only in rainforests, while M. australasicus tends to be found in sclerophyllous forests; the widespread species P. dilatatus tends to be found in wet sclerophyll to rainforest.Published as part of Seeman, Owen D., 2019, The megisthanid mites (Mesostigmata: Megisthanidae) of Australia, pp. 1-40 in Zootaxa 4563 (1) on pages 13-14, DOI: 10.11646/zootaxa.4563.1.1, http://zenodo.org/record/260085
