Venter of body with sparse microscopic setae; carinal prosternal striae very reduced or obsolete; lateral prosternal striae divergent anteriorly; prosternal foveae absent; apex of prosternal process with sulcus. Meso- and metaventrite almost impunctate; lateral disc of metaventrite + metepisternum punctuate and setose. Mandibles of unequal length, left mandible slightly longer than right. Eyes completely flattened, reduced, invisible from above. Sensory structures of antenna in form of a single stipe-shaped vesicle situated under round sensory area on internal distal part of the antennal club complemented by another round sensory area.

7D320C587B6BD35DF76B3936A26217B7.taxon	distribution	Distribution. Bickhardt (1912: 232) following the description of Satrapister nitens in Latin gave ' South America? ' as its terra typica, but explained further in the text in German that the two specimens he examined were found in Goettingen by Dr. A. Reclaire in ' Peru-Guano', and that was why he opted for South America as the continent of origin. The type locality ' South America? ' was repeated by Mazur (1984, 1997, 2011), followed by ' Peru? '. The three non-type specimens collected in the years before and after WWII originate from two tiny islands off the Peruvian coast: Isla Don Martin and Isla de Pescadores [= Isla Grande]. Both these islands serve as important refugia and nesting grounds for numerous species of seabirds and are known to contain large amounts of guano (Cushman 2014).	en	Lackner, Tomas (2016): Satrapisternitens Bickhardt, 1912: redescription and tentative phylogenetic placement of a mysterious taxon (Coleoptera, Histeridae, Saprininae).

E4E42343E738D8B254604BE495B0614A.taxon	description	Description. Body (Figs 1 - 2) PEL: 1.50 - 1.70 mm; APW: 0.625 - 0.65 mm; PPW: 1.00 - 1.125 mm; EW: 1.25 mm; EL: 1.00 mm; colour (including body appendages) light brown to castaneous, antennal club amber-coloured. Clypeus flat, with scattered punctuation; labrum with wide median depression, with two long labral setae arising from each labral pit; mandibles rather slender, left mandible slightly longer than right, both mandibles pointed apically, sub-apical tooth on left mandible situated approximately in mandibular mid-length, obtuse; vague vestiges of frontal stria present anterad eyes, frontal + supraorbital striae otherwise absent; frontal disc flat, with scattered punctuation, punctures separated by several times their diameter, on posterior margin with distinct fovea medially; occipital stria fine, complete. Antennal scape slightly thickened, antennal club round, sensory structures of antennal club (Fig. 3) in form of one stipe-shaped vesicle situated under round sensory area on internal distal side of the antennal club dorsally, bridge-like connected with another sensory area. Antennomeres 1 - 8 with distinct setae. Eyes small (reduced?), flattened, invisible from above; surface above eyes on frontal lateral margins with distinct regular microscopic setae. Pronotal hypomeron punctate, with distinct regular microscopic setae, lateral pronotal margins (Fig. 1) on basal two-thirds almost sub-parallel, on apical third narrowing, anterior pronotal angles obtuse. Pronotal disc laterally with sparse, rather deep elongate punctures separated by their own to several times their diameter; medially disc with scattered microscopic punctuation. Marginal pronotal stria thin, but carinate and complete; pronotal base with a vague row of tiny punctures. Scutellum small, triangular. Elytral epipleuron with several irregular wrinkles and few punctures, otherwise smooth; marginal epipleural stria fine, complete, marginal elytral stria carinate and complete; apical elytral stria obliterated on half its length. Oblique humeral stria deeply impressed on basal elytral fourth; in one specimen a median fragment of inner subhumeral stria as well as a basal fragments of elytral striae 1 - 2 present; in rest of specimens all other elytral striae, except for short basal fragment of fourth dorsal elytral stria that is basally connected to almost complete sutural elytral stria completely lacking. Elytral disc with scattered punctures separated by several times their diameter. Propygidium and pygidium with punctuation similar to the elytra, but punctures deeper and denser, separated approximately twice their diameter. Prosternal process (Fig. 2) on apical margin with distinct, rather long amber setae; marginal prosternal stria present as a median fragment; carinal prosternal striae very weak, usually present only between procoxae, next evanescent (in two specimens intermittent to almost complete); lateral prosternal striae widely divergent anteriorly and ending in apical sulcus; prosternal foveae absent; prosternal keel even, rounded, impunctate, alutaceous. Mesoventrite (Fig. 2) sub-trapezoid, convex, sparsely punctuate, marginal mesoventral stria thin, weak; meso-metaventral sutural stria absent; metaventrite almost smooth, only with several scattered punctures becoming denser along metaventral base; lateral metaventral stria straight, thin, vaguely impressed, shortened; lateral disc of metaventrite with dense deep, almost confluent punctures fringed with long amber setae; metepisternum with similar punctuation. First visible abdominal ventrite vaguely striate laterally, disc almost glabrous, only with scattered microscopic punctuation. Legs: protibia slightly dilated, with 9 - 11 low teeth topped by rather long thin curved denticles diminishing in size in proximal direction, protarsal groove shallow, protibial spur short and stout, growing out from apical protibial margin, further characters of protibia not examined. Mesotibia on outer margin with a row of low teeth topped by long, slender amber-coloured denticles, setae of outer row dense and rather long; setae of median row finer and shorter; on anterior face of mesotibia another row of shorter dense amber denticles present, mesotibial spur stout and well-developed; metatibia slightly longer than mesotibia, denticles on outer metatibial margin more closely-set; metatarsal claws short, bent, about half-length of terminal metatarsal segment; other characters of legs not examined. Male genitalia: eighth sternite (Figs 4 - 5) longitudinally divided medially, apically with tiny velum topped by several microscopic setae; eighth tergite inwardly arcuate apically; eighth sternite and tergite fused laterally (Fig. 6). Ninth tergite (Figs 7, 9) longitudinally separated medially; tenth tergite (Fig. 8) apically with lateral processes; spiculum gastrale (Fig. 10) apically separated into two arms; base distinctly triangular. Aedeagus (Fig. 12) with rather short phallobase, ratio phallobase: tegmen approximately 1: 5; tegmen sub-parallel, faintly dilating apically; apex with pores and pseudo-pores; parameres fused apically and on their basal 2 / 5; aedeagus laterally curved ventrad (Fig. 13).	en	Lackner, Tomas (2016): Satrapisternitens Bickhardt, 1912: redescription and tentative phylogenetic placement of a mysterious taxon (Coleoptera, Histeridae, Saprininae).
