Amphicrossus murrayi sp. n. (Figs 82-90) Specimen examined - "Sarawak: 4th Division, Gn. Mulu NP.", "nr. Camp, c. 1 800 m", "at light", "P.M. Hammond, J.E. Marschall, v-viii.1978" (holotype, male, BMNH). Description of male (holotype) - This new species is rather similar to A. angusticlavis sp. n., so some characters shared by both species are omitted in the description. Length 5.0, width 3.0, height 1.7 mm. Comparatively more convex than other congeners dorsally and slightly ventrally; subunicolorous light brown with lighter appendages (although antennái club dark brown); dorsum with a very faint shine, and underside moderately shining; body with strongly conspicuous fine golden hairs, more than 4-5 times as long as distance between their insertions (on underside pubescence somewhat shorter and less conspicuous) and dorsum also with sparser and much longer hairs; pronotal and elytral sides with dense cilia, consisting of hairs markedly shorter than tarsal claws, becoming very short behind the middle; paramedial brushes of long hairs situated at anterior 2/5 (these hairs about twice as long as hairs in cilia) (Fig. 82). Head, pronotum and elytra with distinct punctures, somewhat smaller than eye facets, interspaces between them somewhat narrower than a puncture diameter, smoothed on head and densely and cellularly microreticulated on pronotum and elytra. Prosternum with obsolete puncturation and smoothed sculpture, but its process with dense indistinct small punctures, interspaces between them smoothly reticulated. Metasternum with distinct and dense punctures, somewhat smaller than those on dorsal sclerites, interspaces between them markedly less than a puncture diameter and rather smoothly microreticulated. Ventrites finely and very densely microgranulose. Antennái club (Fig. 87) comprising about 2/7 of total antennái length, nearly 1 and 1/2 as long as wide, antennomere 3 slightly longer than antennomere 2 and about 1.5 times as long as antennomere 4. Pronotum with posterior edge rather oblique at posterior angles. Elytra slightly shorter as broad combined, their apices rather widely rounded than subtruncate (as those in many congeners). Pygidium very widely rounded to subtruncate at apex. Mentum subquadrangular, about 3 times as wide as long. Prosternum sharply carinate, but its process (Fig. 88) not quite flattened and slightly widened at widely rounded posterior edge. Median plate of mesosternum (Fig. 89) more than 3 times as wide as long, its posterior edge convex. Metasternum subflattened in the middle. Hypopygidium rather deeply and regularly Figs 87-108. 87-90. Amphicrossus murrayi sp. n., male, holotype: 87 = antennái club, 88 = prosternal process, ventral, 89 = median plate of mesosternum, ventral, 90 = apex of last abdominal segment, ventral. 91-100. Amphicrossus opinatus sp. n., male, holotype: 91 = elytron with one of paramedial brushes of long hairs, lateral, 92 = antennái club, 93 = apex of last abdominal segment, ventral, 94 = median process at bottom of apical emargination of hypopygidium, 95 = ventral plate and spiculum gastrale, ventral, 96 = tegmen (left: ventral, right: dorsal, 97 = ibid., lateral, 98 = apex of lateral lobe of tegmen, from view indicated by arrow in Fig. 97,99 = penis trunk, dorsal, 100 = specimen from Laos, apex of lateral lobe of tegmen, from view indicated by arrow in Fig. 97. 101-108. Amphicrossus solodovnikovae sp. n., male, holotype: 101 = elytron with one of paramedial brushes of long hairs, lateral, 102 = apex of last abdominal segment, ventral, 103 = median protuberance at bottom of apical emargination of hypopygidium, 104 = ventral plate and spiculum gastrale, ventral, 105 = tegmen (left: ventral, right: dorsal), 106 - ibid., lateral, 107 = apex of lateral lobe of tegmen, from view indicated by arrow in Fig. 106, 108 = penis trunk, dorsal. Scales: A - to Figs 91,101, B - to Figs 87-90, 92, 93, 102, C - to Figs 95-97, 99, 104-106, 108
