( Figs. 5a–c View Figs , 7B,D View Fig )

Type locality. Brazil, Pará, 8 km E of Belém.

Type material. HOLOTYPE: J, ‘ Brazil: Pará: 8 km E. Belém, Ananindéua , April 20-29, 1973, leg. R.T. Schuh’, ( AMNH).

Diagnosis. The eyes of M. paraensis are smaller and less prominent than in M. elytrata , M. longoelytrata , M. longipes sp. nov., and M. amazonica sp. nov. (the head width / pronotum width ratio of M. paraensis is 0.93). In this respect this species resembles M. unicolor Irmler, 1981 , M adisi Irmler, 2007 and M. hangarthi Irmler, 2007 . Having a small endophallus, the aedeagus of M. paraensis resembles that of M. tricolor Irmler, 1981 ; in contrast to M. tricolor the endophallus of M. paraensis is not distinctly spiral. Moreover, the elytral punctation of M. tricolor is distinctly finer and the microsculpture less distinct than in M. paraensis .

Description. Length: 2.3 mm. Colouration: light reddish brown; legs and antennae yellow.

Head 0.30 mm long, 0.40 mm wide; with slightly prominent eyes; with large setiferous punctures; punctation laterally dense, but with impunctate wide midline on disc; distance between punctures half as wide as or narrower than half width of diameter of punctures; microsculpture on punctate areas weak; surface shiny; surface of impunctate areas glossy.

Antennae as long as head plus ¾ of pronotum; 2 nd antennomere oblong; 3 rd conical as long as 2 nd antennomere; antennomeres 4 to 10 increasing in width, but all more or less quadrate or slightly wider than long.

Pronotum 0.35 mm long, 0.43 mm wide; with coarse setiferous punctures; distance between punctures on average ¼ as wide as diameter of punctures; with wide impunctate midline; netlike microsculpture weak; surface shiny.

Elytra 0.50 mm long, 0.50 mm wide; with dense setiferous punctation; punctures large and coarse and partly coriaceous; distance between punctures less than ¼ of diameter of punctures; microsculpture more distinct than on pronotum; surface less shiny.

Abdomen with distinctly finer punctation than those of pronotum and elytra, but with more distinct microsculpture; surface less shiny than that of elytra.

Legs shorter than pronotum; mesotibia without sexual dimorphism.

Median lobe of aedeagus with sinuous apical part and short endophallus with no distinct spirals.

Etymology. The specific name paraensis is an adjective derived from the state of Pará, where this species was collected
