Type material examined. Holotype ( BPBM; Figs 33, 38 ): ♂, “ Pakading / 27. 10. 64 ”, “ LAOS:/ Borikhane Prov. / Pakkading/ 22. III. 1965 ”, “ J. A. Rondon / Collection / BISHOP Mus. ”, “ Metipocregyes rondoni mihi/ Typ / Breuning déi.”

Other materials examined. 1♂ ( BPBM), same locality as the holotype, 4. X. 1964, Rondon coll. ; 1♀ ( BPBM), “ Phon Tiou ”, Khammouan Prov., Laos, 17. V. 1965, Rondon coll. ; 1♂ ( BPBM), Ban Thonpheng , Vientiane Prov., Laos, 30. XI. 1965, Rondon coll.

Diagnosis. This species is distinguishable from the other congeners by a combination of the following features: body elongate, relatively large; head with frons clothed with whitish pubescence; pronotum and elytra dominantly with brown pubescence.

Redescription. Male ( Figs 18–19, 29 ; n = 2): LB = 10.0– 14.6 mm, WB = 3.8–5.5 mm.

Color varies from dark to reddish brown. Inferior side of antenna and tibiae with light brown or whitish long setae. Head dominantly covered with whitish pubescence, with light brown pubescence on the areas near the margin of frons, between antennal tubercles, and around eye lobes. Antenna with scape, pedicel and each basal part of antennomere 3–11 with light brown and whitish pubescence, and the reminders with brown pubescence. Pronotum and elytra with brown pubescence mottled with light brown and whitish pubescence; elytra scattered with several small tufts of black pubescence on basal swelling and apical half. Legs with femora and tibiae with sparse light brown and whitish pubescence, of which whitish one forms annulation near each middle of tibiae. Ventral surface dominantly with brown and light brown pubescence.

Eye with LL/WL = 1.0, LL/LG = 1.0–1.1. Antenna 1.4 times as long as body; relative length of each segment as follows: 1.1–1.2: 0.2: 1.4: 1.3: 1.0: 0.9: 0.9: 0.8–0.9: 0.8: 0.7–0.8: 0.7. Pronotum LP/WP = 0.9, LP/LB = 0.2, WP/WEH = 0.7; disk with coarse punctures throughout and three obtuse small tubercles on middle; lateral side with small dull projection near apical margin. Elytra with LE/WEH = 1.7–1.8, LE/LB = 0.7, LE/LP = 2.7–2.8; disk with longitudinal obtuse swelling behind base near each middle, several granules on base, and coarse punctures which are distinct, relatively dense in basal half, then sparser, reduced apically and indistinct near weakly emarginate apex.

Male genitalia ( Figs 69–75 ; n = 1): tegmen slightly curved in lateral view. Paramere in dorsal view slightly shorter than the 1/3 length of tegmen, gently constricted in base, gently curved in apical 2/3; ventral side with inwardly directed cylindroid projection behind base. Median lobe weakly curved in lateral view; median strut disjunct behind middle; ventral plate with apex roundly pointed. Endophallus subequal to the twice length of median lobe; PB relatively long; APH rudimental, with ED on distal part. MSp indistinct. LSp distributed in distal 1/3 of MT+CT. SSp densely covered entire part of PB.

Female (n = 1): LB = 13.2 mm, WB = 5.1 mm. Very similar to male, but antenna 1.1 times as long as body; relative length of each segment as follows: 1.4: 0.3: 1.4: 1.3: 1.0: 0.9: 0.9: 0.8: 0.7: 0.7: 0.6.

Distribution. Laos.

Taxonomic notes. This species was originally described under the genus Metipocregyes Breuning, 1939 ( Breuning 1965a) . The genus was comprised of three species: M. nodieri (Pic, 1933) — the type species of the genus, M. affinis Breuning, 1968 , and M. rondoni Breuning, 1965 . By comparison of these three species, M. nodieri and M. affinis are congeneric because due to share the following structure: mesosternal process sulcate medially with ridged lateral margin; tegmen wide rhombic; paramere with ventral side hardly concaved, without distinct projection; endophallus with APH well swollen. Besides, M. rondoni is obviously different from them especially in the following characteristics: mesosternal process with a tubercle on the center near apex; male genitalia with tegmen slender; paramere with inwardly directed projection on ventral side; endophallus with APH rudimentarily swollen. In addition to those structures, the general external and male genital features are well accorded to the revised definition of Anipocregyes . With these justifications, this species is transferred to Anipocregyes . As a result, the species name becomes a secondary homonym of above redescribed species, Anipocregyes rondoni (Breuning, 1965) comb. nov., therefore, Anipocregyes albifrons Yamasako & Makihara , nom. nov. is proposed as a replacement name.
